    Cardiopulmonary resuscitation (CPR) courses meet all the definitions of an educational activity for prevention of cardiac arrest death by risk patients' parents and/or the general population. The aim is to improve patients' home care and turn parents confident before their children are discharged from hospital, mainly from intensive care units. Currently these courses are part of discharge protocols in many neonatologist services although there are offers that exceed this target, and extend to other areas such as education and caregivers. Locally the experience of neonatal CPR at the Sociedad Argentina de Pediatría stands out in connection with delivering courses to high risk patients' parents as well as designing and spreading learning material.

    Extracorporeal life support (ECLS) is used for patients in isolated or combined cardiopulmonary failures. The use of ECLS to rescue patients with cardiac arrest that is refractory to conventional cardiopulmonary resuscitation has been shown to improve survival in many patient populations. Increasing recognition of the survival benefit associated with extracorporeal cardiopulmonary resuscitation (ECPR) has led to increased use of ECPR during the past decade. This review provides an overview of ECPR utilization; population-based clinical outcomes, resource utilization and costs associated this advanced form of life support therapy.

    Forty-one children aged 11-12 years received tuition in cardiopulmonary resuscitation (CPR) and subsequently completed questionnaires to assess their theoretical knowledge and attitudes their likelihood of performing CPR. Although most children scored well on theoretical knowledge, this did not correlate with an assessment of practical ability using training manikins. In particular only one child correctly called for help after the casualty was found to be unresponsive, and none telephoned for an ambulance before starting resuscitation. These omissions have important implications for the teaching of CPR and the resulting effectiveness of community CPR programmes.

    THE ANCIENT TIMES: Many early civilisations left testimonies about ancient times and resuscitation, as well. Some of them did it successfully and some of them did it less successfully; however, all of them wished to help a dying person and to bring him back to life. The first trustworthy note can be found in the Bible--Old Testament as a very realistic description of resuscitation of a child. THE MIDDLE AGES: The medieval scientists, Paracelsus and Vesalius, described first successful resuscitation attempts in the 15th and 16th century. These two men successfully applied ventilation methods by air inflation with blacksmith bellows. THE MODERN ERA: The first defibrillation was recorded in the 18th century in England, which was conducted by one of the volunteer society members. With the development of mechanics and techniques, the first precursors of modern respirators were introduced in the 19th century. The age of modern cardiopulmonary resuscitation began in the middle of 20th century, when Dr Peter Safar brought in the combination of artificial ventilation and chest compressions as the standard for implementing resuscitation. Adrenalin and defibrillation were introduced into the resuscitation techniques by Dr Redding and Dr Kouwenhaven, respectively; thus beginning the advance life support administration, which has been applied, with minor changes, until today.

  7. Cardiopulmonary resuscitation (CPR)-related posterior rib fractures in neonates and infants following recommended changes in CPR techniques.

    Posterior rib fractures are highly indicative of non-accidental trauma (NAT) in infants. Since 2000, the "two-thumbs" technique for cardiopulmonary resuscitation (CPR) of newborns and infants has been recommended by the American Heart Association (AHA). This technique is similar to the grip on an infant's thorax while shaking. Is it possible that posterior rib fractures in newborns and infants could be caused by the "two-thumbs" technique? Using computerized databases from three German children's hospitals, we identified all infants less than 12 months old who underwent professional CPR within a 10-year period. We included all infants with anterior-posterior chest radiographs taken after CPR. Exclusion criteria were sternotomy, osteopenia, various other bone diseases and NAT. The radiographs were independently reviewed by the Chief of Pediatric Radiology (MB) and a Senior Pediatrician, Head of the local Child Protection Team (IF). Eighty infants with 546 chest radiographs were identified, and 50 of those infants underwent CPR immediately after birth. Data concerning the length of CPR was available for 41 infants. The mean length of CPR was 11min (range: 1-180min, median: 3min). On average, there were seven radiographs per infant. A total of 39 infants had a follow-up radiograph after at least 10 days. No rib fracture was visible on any chest X-ray. The results of this study suggest rib fracture after the use of the "two-thumbs" CPR technique is uncommon. Thus, there should be careful consideration of abuse when these fractures are identified, regardless of whether CPR was performed and what technique used. The discovery of rib fractures in an infant who has undergone CPR without underlying bone disease or major trauma warrants a full child protection investigation.

    Challenged by the continued high mortality rates for patients in cardiac arrest, the American Heart Association and the European Resuscitation Council developed a new set of guidelines in 2000 to help advance several new and promising cardiopulmonary resuscitation (CPR) techniques and devices. This is the first time these organizations have taken such a bold move, in part because of the poor results with standard closed-chest cardiac massage. The new techniques, interposed abdominal counterpulsation and active compression decompression CPR, each provide greater blood flow to the vital organs in animal models of CPR and lead to higher blood pressures in patients in cardiac arrest. In some clinical studies, both techniques have resulted in a significant increase in survival after cardiac arrest in comparison with standard CPR. Three of the four new CPR devices that were recommended in the new guidelines also provide superior vital organ blood flow and increased blood pressures in comparison with standard CPR. The three devices that improve the efficiency of CPR are the circumferential vest, an active compression decompression CPR device, and an inspiratory impedance valve used in combination with the active compression decompression CPR device. The fourth device type, one that compresses the thorax using an automated mechanical piston compression mechanism, was recommended to reduce the number of personnel required to perform CPR. However, no studies on the automated mechanical compression devices have showed an improvement in hemodynamic variables or survival in comparison with standard CPR. Taken together, these new technologies represent an important step forward in the evolution of CPR from a pair of hands to devices designed to enhance CPR efficiency. Each of these advances is described, and the recent literature about each of them is reviewed.

    2007-05-01

    In medical practice, the different scenarios in which cardio respiratory resuscitation (CPR) may be applied must be taken into account. CPR is crucial in subjects that arrive in emergency rooms or suffer a cardiac arrest in public places or at their homes. It is also critical in hospitalized patients with potentially reversible diseases, who suffer cardiac arrest as an unexpected event during their evolution. In intensive care units, the decision is particularly complex. The concepts of therapeutic proportionality, treatment futility and therapeutic tenacity can help physicians in their decision making about when CPR is technically and morally mandatory. The do not resuscitate (DNR) decision in taken when a patient is bearing an irreversible disease and his life is coming to an end. DNR decisions are clearly indicated in intensive care units to limit the therapeutic effort and in other hospital facilities, when death is foreseeable and therapeutic tenacity must be avoided. DNR orders must be renewed and reconsidered on a daily basis. It does not mean that other treatment should be discontinued and by no means should the patient be abandoned. DNR and previous directives, DNR and quality of life and DNR communication are also commented in the present article.

    The optimal management of newborns with asphyxia is closely associated with improved survival and a better quality of life without neuromotor handicaps. Therefore, the training of health professionals who are present at the time of birth in neonatal resuscitation should be a priority. In the present article, we present a program of training courses in neonatal resuscitation. This program has been designed for the training of health care providers and instructors in technical aspects of neonatal resuscitation. The type of courses, their contents and methodology are described.

    Knowledge of the physiological mechanisms that govern cardiopulmonary interactions during cardiopulmonary resuscitation (CPR) allows to better assess risks and benefits of ventilation. Ventilation is required to maintain gas exchange, particularly when CPR is prolonged. Nevertheless, conventional ventilation (bag mask or mechanical ventilation) may be harmful when excessive or when chest compressions are interrupted. In fact large tidal volume and/or rapid respiratory rate may adversely compromise hemodynamic effects of chest compressions. In this regard, international recommendations that give the priority to chest compressions, are meaningful. Continuous flow insufflation with oxygen that generates a moderate positive airway pressure avoids any interruption of chest compressions and prevents the risk of lung injury associated with prolonged resuscitation.

    That endogenous vasopressin levels in successfully resuscitated human patients were significantly higher than in patients who died pointed to the possible benefit of administering vasopressin during cardiopulmonary resuscitation (CPR). Several CPR studies in pigs showed that vasopressin improved blood flow to vital organs, cerebral oxygen delivery, resuscitability and neurological outcome when compared with epinephrine. In a small clinical study, vasopressin significantly improved short-term survival when compared with epinephrine indicating its potential as an alternative pressor to epinephrine during CPR in human beings. As there was little clinical data available at that time, its recommended use was limited to adult human beings with shock-refractory ventricular fibrillation. In this report, we present the case of a dog in which the successful management of intraoperative asystolic cardiac arrest involved vasopressin. Unexpected cardiac arrest occurred during anaesthesia for the surgical removal of multiple mammary adenocarcinomata in a 11-year-old Yorkshire terrier. Despite an ASA physical status assignation of III, the dog was successfully resuscitated with external chest compressions, intermittent positive pressure ventilation and vasopressin (2 doses of 0.8 IU kg(-1)) and was discharged 3 days later without signs of neurological injury. We believe vasopressin contributed to restoring spontaneous circulation. It may prove increasingly useful in perioperative resuscitation in dogs.

    Electrical shock is typically an untoward exposure of human body to any source of electricity that causes a sufficient current to pass through the skin, muscles or hair causing undesirable effects ranging from simple burns to death. Ventricular fibrillation is believed to be the most common cause of death following electrical shock. The case under discussion is of a young man who survived following electrical shock after prolonged cardiopulmonary resuscitation (CPR), multiple defibrillations and artificial ventilation due to poor respiratory effort. Early start of chest compressions played a vital role in successful CPR.

    Community instruction in basic life support and resuscitation techniques has been offered in Brighton Health District since 1978. Classes are held frequently for the general public and businesses, schools, and other organisations. First aid care for unconscious patients, the treatment of respiratory obstruction or failure, and the recognition and management of cardiac arrest is taught in a single two hour session. Over 20 000 people have been taught, up to 40 at a time in multiple groups of six to eight, by lay instructors usually supervised by ambulancemen trained to "paramedic" standards. Fifty four incidents have been reported to us in which techniques learnt in the classes have been implemented. Five patients recovered after first aid support but subsequently did not seek medical treatment. Of the 34 patients reviewed in hospital, at least 20 survived to be discharged. We believe that intervention may have been life saving in 16 instances. The benefit of cardiopulmonary resuscitation for victims who may have been asystolic is, however, difficult to quantify because the outcome without intervention cannot be predicted accurately. Community training in basic life support should be considered in association with ambulances equipped for resuscitation and hospital intensive care and cardiac care units as an integrated service for the victims of sudden circulatory or respiratory emergencies. The results achieved so far in Brighton and in other more advanced schemes, particularly in the United States of America, may encourage other health authorities to adopt similar programmes.

    More than 25% of children survive to hospital discharge after in-hospital cardiac arrests, and 5% to 10% survive after out-of-hospital cardiac arrests. This review of pediatric cardiopulmonary resuscitation addresses the epidemiology of pediatric cardiac arrests, mechanisms of coronary blood flow during cardiopulmonary resuscitation, the 4 phases of cardiac arrest resuscitation, appropriate interventions during each phase, special resuscitation circumstances, extracorporeal membrane oxygenation cardiopulmonary resuscitation, and quality of cardiopulmonary resuscitation. The key elements of pathophysiology that impact and match the timing, intensity, duration, and variability of the hypoxic-ischemic insult to evidence-based interventions are reviewed. Exciting discoveries in basic and applied-science laboratories are now relevant for specific subpopulations of pediatric cardiac arrest victims and circumstances (eg, ventricular fibrillation, neonates, congenital heart disease, extracorporeal cardiopulmonary resuscitation). Improving the quality of interventions is increasingly recognized as a key factor for improving outcomes. Evolving training strategies include simulation training, just-in-time and just-in-place training, and crisis-team training. The difficult issue of when to discontinue resuscitative efforts is addressed. Outcomes from pediatric cardiac arrests are improving. Advances in resuscitation science and state-of-the-art implementation techniques provide the opportunity for further improvement in outcomes among children after cardiac arrest. PMID:18977991

    Cardiopulmonary Resuscitation (CPR) must be attempted if indicated, not done if it is not indicated or if the patient does not accept or has previously rejected it and withdrawn it if it is ineffective. If CPR is considered futile, a Do-Not-Resuscitate Order (DNR) will be recorded. This should be made known to all physicians and nurses involved in patient care. It may be appropriate to limit life-sustaining-treatments for patients with severe anoxic encephalopathy, if the possibility of clinical evolution to brain death is ruled out. After CPR it is necessary to inform and support families and then review the process in order to make future improvements. After limitation of vital support, certain type of non-heart-beating-organ donation can be proposed. In order to acquire CPR skills, it is necessary to practice with simulators and, sometimes, with recently deceased, always with the consent of the family. Research on CPR is essential and must be conducted according to ethical rules and legal frameworks.

    The maximal duration of cardiopulmonary resuscitation (CPR) is unknown. We report a case of prolonged CPR. We have then reviewed all published cases with CPR duration equal to or more than 20 minutes. The objective was to determine the survival rate, the neurological outcome, and the characteristics of the survivors. Measurements and Main Results. The CPR data for 82 patients was reviewed. The median duration of CPR was 75 minutes. Patients mean age was 43 ± 21 years with no significant comorbidities. The main causes of the cardiac arrests were myocardial infarction (29%), hypothermia (21%), and pulmonary emboli (12%). 74% of the arrests were witnessed, with a mean latency to CPR of 2 ± 6 minutes and good quality chest compression provided in 96% of the cases. Adjunct therapy included extracorporeal membrane oxygenation (18%), thrombolysis (15.8%), and rewarming for hypothermia (19.5%). 83% were alive at 1 year, with full neurological recovery reported in 63 patients. Conclusion. Patients undergoing prolonged CPR can survive with good outcome. Young age, myocardial infarction, and potentially reversible causes of cardiac arrest such as hypothermia and pulmonary emboli predict a favorable result, especially when the arrest is witnessed and followed by prompt and good resuscitative efforts.

    Although high quality cardiopulmonary resuscitation is one of the most significant factors related to favourable outcome, its quality depends on many components, such as airway management, compression depth and chest recoil, hands-off time, and early defibrillation. The most common way of controlling the resuscitation efforts is monitoring of end-tidal carbon dioxide. The International Liaison Committee on Resuscitation suggests this method both for in-hospital and out-of-hospital cardiac arrest. However, despite the abundant human and animal studies supporting the usefulness of end-tidal carbon dioxide, its optimal values during cardiopulmonary resuscitation remain controversial. In this review, the advantages and effectiveness of end-tidal carbon dioxide during cardiopulmonary resuscitation are discussed and specific target values are suggested based on the available literature.

    Abstract This paper aims to analyze agreement in the assessment of external chest compressions (ECC) by 3 human raters and dedicated feedback software. While 54 volunteer health workers (medical transport technicians), trained and experienced in cardiopulmonary resuscitation (CPR), performed a complete sequence of basic CPR maneuvers on a manikin incorporating feedback software (Laerdal PC v 4.2.1 Skill Reporting Software) (L), 3 expert CPR instructors (A, B, and C) visually assessed ECC, evaluating hand placement, compression depth, chest decompression, and rate. We analyzed the concordance among the raters (A, B, and C) and between the raters and L with Cohen's kappa coefficient (K), intraclass correlation coefficients (ICC), Bland–Altman plots, and survival–agreement plots. The agreement (expressed as Cohen's K and ICC) was ≥0.54 in only 3 instances and was ≤0.45 in more than half. Bland–Altman plots showed significant dispersion of the data. The survival–agreement plot showed a high degree of discordance between pairs of raters (A–L, B–L, and C–L) when the level of tolerance was set low. In visual assessment of ECC, there is a significant lack of agreement among accredited raters and significant dispersion and inconsistency in data, bringing into question the reliability and validity of this method of measurement.

    Cardiopulmonary resuscitation (CPR) techniques were investigated in microgravity with specific application to planned medical capabilities for Space Station Freedom (SSF). A KC-135 parabolic flight test was performed with the goal of evaluating and quantifying the efficacy of different types of microgravity CPR techniques. The flight followed the standard 40 parabola profile with 20 to 25 seconds of near-zero gravity in each parabola. Three experiments were involved chosen for their clinical background, certification, and practical experience in prior KC-135 parabolic flight. The CPR evaluation was performed using a standard training mannequin (recording resusci-Annie) which was used in practice prior to the actual flight. Aboard the KC-135, the prototype medical restraint system (MRS) for the SSF Health Maintenance Facility (HMF) was used for part of the study. Standard patient and crew restraints were used for interface with the MRS. During the portion of study where CPR was performed without MRS, a set of straps for crew restraint similar to those currently employed for the Space Shuttle program were used. The entire study was recorded via still camera and video.

    This review main purpose is to show nursing the present knowledge about cardiopulmonary resuscitation (CPR) in pregnant women because of the scarce information published by Spanish Nursing Publications. The bibliographical research was made using both the Medline (from January 1982 to March 1998) and Index de Enfermería databases. There, we can find 32 references from which only 23 were selected (all of them belong to the Medline database) in spite of 3 chapters that had already been selected from other different books. Although maternal cardiac arrest rarely happens during pregnancy, it is very important for sanitary staff to be familiarized with the specifics thecnics and equipment (ultrasound and cardiotocograph monitoring). This review describes the physiological changes that take place during pregnancy and have an incidence into CPR. The article also includes the conclusions about the checked papers and the peculiarities that have to be taken into account in each CPR, such as the fetal viability evaluation, right CPR position, airway and breathing, desfibrillation, external cardiac compression and use of pharmacologic therapy and intravenous fluids. Moreover, there is a special mention of the perimortem cesarean delivery features: antecedents, foetus-maternals consequences and managements, due to the fact that this surgical operation should be included inside the CPR protocols of the pregnant.

    Objective: To identify literature evidences related to actions to promote family's presence during cardiopulmonary resuscitation and invasive procedures in children hospitalized in pediatric and neonatal critical care units. Data sources : Integrative literature review in PubMed, SciELO and Lilacs databases, from 2002 to 2012, with the following inclusion criteria: research article in Medicine, or Nursing, published in Portuguese, English or Spanish, using the keywords "family", "invasive procedures", "cardiopulmonary resuscitation", "health staff", and "Pediatrics". Articles that did not refer to the presence of the family in cardiopulmonary resuscitation and invasive procedures were excluded. Therefore, 15 articles were analyzed. Data synthesis : Most articles were published in the United States (80%), in Medicine and Nursing (46%), and were surveys (72%) with healthcare team members (67%) as participants. From the critical analysis, four themes related to the actions to promote family's presence in invasive procedures and cardiopulmonary resuscitation were obtained: a) to develop a sensitizing program for healthcare team; b) to educate the healthcare team to include the family in these circumstances; c) to develop a written institutional policy; d) to ensure the attendance of family's needs. Conclusions: Researches on these issues must be encouraged in order to help healthcare team to modify their practice, implementing the principles of the Patient and Family Centered Care model, especially during critical episodes.

    For decades, survival rates of cardiac arrest following trauma were reported between 0 and 2 %. Since 2005, survival rates have increased with a wide range up to 39 % and good neurological recovery in every second person injured for unknown reasons. Especially in children, high survival rates with good neurologic outcomes are published. Resuscitation following traumatic cardiac arrest differs significantly from nontraumatic causes. Paramount is treatment of reversible causes, which include massive bleeding, hypoxia, tension pneumothorax, and pericardial tamponade. Treatment of reversible causes should be simultaneous. Chest compression is inferior following traumatic cardiac arrest and should never delay treatment of reversible causes of the traumatic cardiac arrest. In massive bleeding, bleeding control has priority. Damage control resuscitation with permissive hypotension, aggressive coagulation therapy, and damage control surgery represent the pillars of initial treatment. Cardiac arrest due to hypoxia should be resolved by airway management and ventilation. Tension pneumothorax should be decompressed by finger thoracostomy, pericardial tamponade by resuscitative thoracotomy. In addition, resuscitative thoracotomy allows direct and indirect bleeding control. Untreated impact brain apnea may rapidly lead to cardiac arrest and requires quick opening of the airway and effective oxygenation. Established algorithms for treatment of cardiac arrest following trauma enable a safe, structured, and effective management.

    A viscoelastic model is presented to describe the dynamic response of the human chest to cyclic loading during manual cardiopulmonary resuscitation (CPR). Sternal force and displacement were measured during 16 clinical resuscitation attempts and during compressions on five CPR training manikins. The model was developed to describe the clinical data and consists of the parallel combination of a spring and dashpot. The human chests' elastic and damping properties were both augmented with increasing displacement. The manikins' elastic properties were stiffer and both elastic and damping properties were less dependent on displacement than the humans'.

Design Laboratory investigation Setting University Laboratory Subjects Pigs Interventions Animals underwent 30-minute untreated ventricular fibrillation cardiac arrest followed by extracorporeal cardiopulmonary resuscitation (ECPR) for 6 hours. Animals were allocated into two experimental groups: t-ECPR, which received Streptokinase 1 MU and c-ECPR which did not receive Streptokinase. In both groups the resuscitation protocol included the following physiologic targets: mean arterial pressure (MAP) > 70 mmHg, Cerebral perfusion pressure (CerPP) > 50 mmHg, PaO2 150 ± 50 mmHg, PaCO2 40 ± 5 mmHg and core temperature 33 ± 1 °C. Defibrillation was attempted after 30 minutes of ECPR. Measurements and Main Results A cardiac resuscitability score was assessed on the basis of: success of defibrillation; return of spontaneous heart beat; weanability form ECPR; and left ventricular systolic function after weaning. The addition of thrombolytic to ECPR significantly improved cardiac resuscitability (3.7 ± 1.6 in t-ECPR vs 1.0 ± 1.5 in c-ECPR). Arterial lactate clearance was higher in t-ECPR than in c-ECPR (40 ± 15% VS 18 ± 21 %). At the end of the experiment, the intracranial pressure was significantly higher in c-ECPR than in t-ECPR. Recovery of brain electrical activity, as assessed by quantitative analysis of EEG signal, and ischemic neuronal injury on histopathologic examination did not differ between groups. Animals in t-ECPR group did not have increased bleeding complications, including intracerebral hemorrhages. Conclusions In a porcine model of prolonged cardiac arrest, thrombolytic-enhanced ECPR improved cardiac resuscitability and reduced brain edema, without increasing bleeding complications. However, early EEG recovery and ischemic neuronal injury were

    "Electrical shock is the physiological reaction or injury caused by electric current passing through the human body. It occurs upon contact of a human body part with any source of electricity that causes a sufficient current through the skin, muscles, or hair causing undesirable effects ranging from simple burns to death." Ventricular fibrillation is believed to be the most common cause of death after electrical shock. "The ideal duration of cardiac resuscitation is unknown. Typically prolonged cardiopulmonary resuscitation is associated with poor neurologic outcomes and reduced long term survival. No consensus statement has been made and traditionally efforts are usually terminated after 15-30 minutes." The case under discussion seems worthy of the somewhat detailed description given. It is for a young man who survived after 65 minutes after electrical shock (ES) after prolonged high-quality cardiopulmonary resuscitation (CPR), multiple defibrillations, and artificial ventilation without any sequelae. Early start of adequate chest compressions and close adherence to advanced cardiac life support protocols played a vital role in successful CPR.

    Purpose Cerebral oxidative stress and metabolic dysfunction impede neurological recovery from cardiac arrest-resuscitation. Pyruvate, a potent antioxidant and energy-yielding fuel, has been shown to protect against oxidant- and ischemia-induced neuronal damage. This study tested whether acute pyruvate treatment during cardiopulmonary resuscitation can prevent neurological dysfunction and cerebral injury following cardiac arrest. Methods Anesthetized, open-chest mongrel dogs underwent 5 min cardiac arrest, 5 min open chest cardiac compression (OCCC), defibrillation and 3 day recovery. Pyruvate (n = 9) or NaCl volume control (n = 8) were administered (0.125 mmol/kg/min iv) throughout OCCC and the first 55 min recovery. Sham dogs (n = 6) underwent surgery and recovery without cardiac arrest-resuscitation. Results Neurological deficit score (NDS), evaluated at 2 day recovery, was sharply increased in NaCl-treated dogs (10.3 ± 3.5) vs. shams (1.2 ± 0.4), but pyruvate treatment mitigated neurological deficit (NDS = 3.3 ± 1.2; P < 0.05 vs. NaCl). Brain samples were taken for histological examination and evaluation of inflammation and cell death at 3 d recovery. Loss of pyramidal neurons in the hippocampal CA1 subregion was greater in the NaCl controls than in pyruvate treated dogs (11.7 ± 2.3% vs. 4.3 ± 1.2%; P < 0.05). Cardiac arrest increased caspase 3 activity, matrix metalloproteinase activity, and DNA fragmentation in the CA1 subregion; pyruvate prevented caspase-3 activation and DNA fragmentation, and suppressed matrix metalloproteinase activity. Conclusion Intravenous pyruvate therapy during cardiopulmonary resuscitation prevents initial oxidative stress and neuronal injury and enhances neurological recovery from cardiac arrest.

    Since the 1970s, most of the research and debate regarding interventions for cardiopulmonary arrest have focused on advanced life support (ALS) therapies and early defibrillation strategies. During the past decade, however, international guidelines for cardiopulmonary resuscitation (CPR) have not only emphasized the concept of uninterrupted chest compressions, but also improvements in the timing, rate and quality of those compressions. In essence, it has been a ''revolution'' in resuscitation medicine in terms of ''coming full circle'' to the 1960s when basic CPR was first developed. Recent data have indicated the need for minimally-interrupted chest compressions with an accompanying emphasis toward removing rescue ventilation altogether in sudden cardiac arrest, at least in the few minutes after a sudden unheralded collapse. In other studies, transient delays in defibrillation attempts and ALS interventions are even recommended so that basic CPR can be prioritized to first restore and maintain better coronary artery perfusion. New devices have now been developed to modify, in real-time, the performance of basic CPR, during both training and an actual resuscitative effort. Several new adjuncts have been created to augment chest compressions or enhance venous return and evolving technology may now be able to identify ventricular fibrillation (VF) without interrupting chest compressions. A renewed focus on widespread CPR training for the average person has also returned to center stage with ground-breaking training initiatives including validated video-based adult learning courses that can reliably teach and enable long term retention of basic CPR skills and automated external defibrillator (AED) use.

    BACKGROUND: Dentists as health care providers should maintain a competence in resuscitation. This cannot be overemphasized by the fact that the population in our country is living longer with an increasing proportion of medically compromised persons in the general population. This preliminary study aimed to assess the knowledge and attitude of general dentists towards cardiopulmonary resuscitation (CPR). METHODS: A cross-sectional study was carried out among 250 licensed general dental practitioners working in ministry of health. Data were obtained through electronic self-administered questionnaire consisting of demographic data of general dentists, and their experience, attitude and knowledge about CPR based on the 2010 American Heart Association guidelines update for CPR. RESULTS: Totally 208 general dentists took part in the present study giving a response rate of 83.2%. Only 36% of the participants demonstrated high knowledge on CPR, while 64% demonstrated low knowledge. Participants’ age, gender, nationality, years of experience, career hierarchy, and formal CPR training were associated significantly with CPR knowledge. Almost all the participants (99%) felt that dentists needed to be competent in basic resuscitation skills and showed a positive attitude towards attending continuing dental educational programs on CPR. CONCLUSION: This study showed that majority of general dental practitioners in Kuwait had inadequate knowledge on CPR. It was also found that CPR training significantly influenced the CPR knowledge of the participants. Therefore, training courses on CPR should be regularly provided to general dentists in the country.

    In light of the medically relevant features of the ancient Egyptian mouth-opening ceremony, the question of the effectiveness of medical practices in Egypt thousands of years ago is examined, whereby the religious and cultural framework also plays a significant role. In the Land on the Nile myth and reality clearly generated special conditions which favoured the systematic treatment of questions of resuscitation. Numerous examples show that this had practical consequences in the area of everyday medicine. In addition, rebirth and resurrection were central elements of the cult of the dead which had exact medical equivalents. These equivalents may demonstrate the advanced state of resuscitation practices in Egypt at that time. In this context, a reconstruction of an ancient Egyptian mouth-opening instrument is presented. In the cult of the dead, this instrument played a role which can be compared to the function of a modern laryngoscope. It appears possible that at the time of the pyramids the Egyptians already had an understanding of the technology required to perform instrument-aided artificial respiration. Whether or not they actually possessed a fundamental knowledge of the principles of cardio-pulmonary resuscitation remains unclear. Nevertheless, the astonishingly functional characteristics of the reconstructed mouth-opening instrument suggest that it was developed for more than purely symbolic purposes.

    Although early cardiopulmonary resuscitation (CPR) is associated with increased survival of sudden cardiac arrest victims, it may also result in miscellaneous injuries. A 25-year-old inebriated man rescued from drowning in a swimming pool was apnoeic and pulseless after being pulled out of the water. Successful CPR was provided by untrained bystanders, including abdominal thrusts thought to remove water from the airways and chest compressions to provide haemodynamic support. As the patient progressively improved during his subsequent hospital stay, he complained of right upper abdominal and thoracic pain. A computed tomographic scan showed a 11 cm subcapsular haematoma contiguous to the right hepatic lobe. A favourable outcome was obtained after conservative, non-operative treatment. Subcapsular haematoma of the liver is a potentially life threatening complication that warrants consideration in survivors of cardiac arrest who have received closed chest compression and/or abdominal thrusts.

    Abstract We investigated the effects of dyadic training on medical students’ resuscitation performance during cardiopulmonary resuscitation (CPR) training. We provided students with a 2-hour training session on CPR for simulated cardiac arrest. Student teams were split into double groups (Dyad training groups: Groups A and B) or Single Groups. All groups received 2 CPR simulation rounds. CPR simulation training began with peer demonstration for Group A, and peer observation for Group B. Then the 2 groups switched roles. Single Groups completed CPR simulation without peer observation or demonstration. Teams were then evaluated based on leadership, teamwork, and team member skills. Group B had the highest first simulation round scores overall (P = 0.004) and in teamwork (P = 0.001) and team member skills (P = 0.031). Group B also had the highest second simulation round scores overall (P < 0.001) and in leadership (P = 0.033), teamwork (P < 0.001), and team member skills (P < 0.001). In the first simulation, there were no differences between Dyad training groups with those of Single Groups in overall scores, leadership scores, teamwork scores, and team member scores. In the second simulation, Dyad training groups scored higher in overall scores (P = 0.002), leadership scores (P = 0.044), teamwork scores (P = 0.005), and team member scores (P = 0.008). Dyad training groups also displayed higher improvement in overall scores (P = 0.010) and team member scores (P = 0.022). Dyad training was effective for CPR training. Both peer observation and demonstration for peers in dyad training can improve student resuscitation performance. PMID:28353555

    Mass cardiopulmonary resuscitation (CPR) 99 in Singapore was a large-scale multi-organisational effort to increase awareness and impart basic cardiac life support skills to the lay public. Mass CPR demonstrations followed by small group manikin practice with instructor guidance was conducted simultaneously in three centres, four times a day. The exercise enlisted 15 community organisations and received the support of 19 other organisations. Three hundred and ninety-eight manikins and 500 instructors ('I's) were mobilised to teach an audience of 6000 participants ('P's). Two surveys, for 'I's and 'P's were conducted with respondent rates of 65.8% and 50%, respectively. 73.6% of the P-respondents ('P-R's) indicated that they attended the event to increase their knowledge. 66.9% were willing to attend a more comprehensive CPR course. Concerns and perceptions in performing bystander CPR were assessed.

    The group of experts appointed to review specific resuscitation topics and identify knowledge gaps. The experts compiled and organized these knowledge gaps and, through a process of consultation and consensus, identified areas of priority for clinical research. The process included evidence evaluation, review of the literature, and focused analysis. The results, recommendations and guidelines were published 2007 in basic journals for CPR (Circulation and Resuscitation). We compared some of them with the clinical trials in cardiopulmonary resuscitation in Center for Emergency Medicine Maribor.

    Background Diseases of the circulatory system are the most common cause of death in Brazil. Because the general population is often the first to identify problems related to the circulatory system, it is important that they are trained. However, training is challenging owing to the number of persons to be trained and the maintenance of training. Objectives To assess the delivery of a medical-student led cardiopulmonary resuscitation (CPR) training program and to assess prior knowledge of CPR as well as immediate and delayed retention of CPR training among middle school students. Methods Two public and two private schools were selected. CPR training consisted of a video class followed by practice on manikins that was supervised by medical students. Multiple choice questionnaires were provided before, immediately after, and at 6 months after CPR training. The questions were related to general knowledge, the sequence of procedures, and the method to administer each component (ventilation, chest compression, and automated external defibrillation). The instructors met in a focus group after the sessions to identify the potential problems faced. Results In total, 147 students completed the 6-month follow-up. The public school students had a lower prior knowledge, but this difference disappeared immediately after training. After the 6-month follow-up period, these public school students demonstrated lower retention. The main problem faced was teaching mouth-to-mouth resuscitation. Conclusions The method used by medical students to teach middle school students was based on the watch-and-practice technique. This method was effective in achieving both immediate and late retention of acquired knowledge. The greater retention of knowledge among private school students may reflect cultural factors.

    Objectives. Studies have shown that healthcare personnel hesitate to perform defibrillation due to individual or organisational attitudes. We aimed to assess trainers' attitudes towards cardiopulmonary resuscitation and defibrillation (CPR-D), Current Care Guidelines, and associated training. Methods. A questionnaire was distributed to CPR trainers attending seminars in Finland (N = 185) focusing on the updated national Current Care Guidelines 2011. The questions were answered using Likert scale (1 = totally disagree, 7 = totally agree). Factor loading of the questionnaire was made using maximum likelihood analysis and varimax rotation. Seven scales were constructed (Hesitation, Nurse's Role, Nontechnical Skill, Usefulness, Restrictions, Personal, and Organisation). Cronbach's alphas were 0.92-0.51. Statistics were Student's t-test, ANOVA, stepwise regression analysis, and Pearson Correlation. Results. The questionnaire was returned by 124/185, 67% CPR trainers, of whom two-thirds felt that their undergraduate training in CPR-D had not been adequate. Satisfaction with undergraduate defibrillation training correlated with the Nontechnical Skills scale (p < 0.01). Participants scoring high on Hesitation scale (p < 0.01) were less confident about their Nurse's Role (p < 0.01) and Nontechnical Skills (p < 0.01). Conclusion. Quality of undergraduate education affects the work of CPR trainers and some feel uncertain of defibrillation. The train-the-trainers courses and undergraduate medical education should focus more on practical scenarios with defibrillators and nontechnical skills.

    Objective The objective of this study was to analyze the clinical profile of patients with in-hospital cardiac arrest using the Utstein style. Methods This study is an observational, prospective, longitudinal study of patients with cardiac arrest treated in intensive care units over a period of 1 year. Results The study included 89 patients who underwent cardiopulmonary resuscitation maneuvers. The cohort was 51.6% male with a mean age 59.0 years. The episodes occurred during the daytime in 64.6% of cases. Asystole/bradyarrhythmia was the most frequent initial rhythm (42.7%). Most patients who exhibited a spontaneous return of circulation experienced recurrent cardiac arrest, especially within the first 24 hours (61.4%). The mean time elapsed between hospital admission and the occurrence of cardiac arrest was 10.3 days, the mean time between cardiac arrest and cardiopulmonary resuscitation was 0.68 min, the mean time between cardiac arrest and defibrillation was 7.1 min, and the mean duration of cardiopulmonary resuscitation was 16.3 min. Associations between gender and the duration of cardiopulmonary resuscitation (19.2 min in women versus 13.5 min in men, p = 0.02), the duration of cardiopulmonary resuscitation and the return of spontaneous circulation (10.8 min versus 30.7 min, p < 0.001) and heart disease and age (60.6 years versus 53.6, p < 0.001) were identified. The immediate survival rates after cardiac arrest, until hospital discharge and 6 months after discharge were 71%, 9% and 6%, respectively. Conclusions The main initial rhythm detected was asystole/bradyarrhythmia; the interval between cardiac arrest and cardiopulmonary resuscitation was short, but defibrillation was delayed. Women received cardiopulmonary resuscitation for longer periods than men. The in-hospital survival rate was low. PMID:28099640

    Background: One dilemma in the end-of-life care is making decisions for conducting cardiopulmonary resuscitation (CPR). This dilemma is perceived in different ways due to the influence of culture and religion. This study aimed to understand the experiences of CPR team members about the do-not-resuscitate order. Methods: CPR team members were interviewed, and data were analyzed using a conventional content analysis method. Results: Three categories and six subcategories emerged: “The dilemma between revival and suffering” with the subcategories of “revival likelihood” and “death as a cause for comfort;” “conflicting situation” with the subcategories of “latent decision” and “ambivalent order;” and “low-quality CPR” with the subcategories of “team member demotivation” and “disrupting CPR performance.” Conclusion: There is a need for the development of a contextual guideline, which is required for respecting the rights of patients and their families and providing legal support to health-care professionals during CPR.

    Research Objective. This study determined the outcome of cardiopulmonary resuscitation (CPR) after in-hospital cardiac arrest and factors influencing it in two training hospitals in Ahvaz. Method. Patients hospitalized in the pediatric wards and exposed to CPR during hospital stay were included in the study (September 2013 to May 2014). The primary outcome of CPR was assumed to be the return of spontaneous circulation (ROSC) and the secondary outcome was assumed to be survival to discharge. The neurological outcome of survivors was assessed using the Pediatric Cerebral Performance Category (PCPC) method. Results. Of the 279 study participants, 138 patients (49.4%) showed ROSC, 81 patients (29%) survived for 24 hours after the CPR, and 33 patients (11.8%) survived to discharge. Of the surviving patients, 16 (48.5%) had favorable neurological outcome. The resuscitation during holidays resulted in fewer ROSC. Multivariate analysis showed that longer CPR duration, CPR by junior residents, growth deficiency, and prearrest vasoactive drug infusion were associated with decreased survival to discharge (p < 0.05). Infants and patients with respiratory disease had higher survival rates. Conclusion. The rate of successful CPR in our study was lower than rates reported by developed countries. However, factors influencing the outcome of CPR were similar. These results reflect the necessity of paying more attention to pediatric CPR training, postresuscitation conditions, and expansion of intensive care facilities. PMID:27293983

    Cardiopulmonary resuscitation is required training for all astronauts. No studies thus far have investigated how chest compressions may be affected in lunar and Martian gravities. Therefore a theoretical quantitative study was performed. The maximum downward force an unrestrained person can apply is mg N (g(sub Earth) = 9.78 ms(sup -2), g(sub moon) = 1.63 ms(sup -2), g(sub Mars) = 3.69 ms(sup -2). Tsitlik et a1 (Critical Care Medicine, 1983) described the human sternal elastic force-displacement relationship (compliance) by: F = betaD(sub s) + gammaD(sub s)(sup 2) (beta = 54.9 plus or minus 29.4 Ncm(sup -1) and gamma = 10.8 plus or minus 4.1 Ncm(sup -2)). Maximum forces in the 3 gravitational fields produced by 76 kg (US population mean), 41 kg and 93 kg (masses derived from the limits for astronaut height), produced solutions for compression depth using Tsitlik equations for chests of: mean compliance (beta = 54.9, gamma = 10.8), low compliance (beta = 84.3, gamma = 14.9) and high compliance (beta = 25.5, gamma = 6.7). The mass for minimum adequate adult compression, 3.8 cm (AHA guidelines), was also calculated. 76 kg compresses the mean compliance chest by: Earth, 6.1 cm, Mars, 3.2 cm, Moon, 1.7 cm. In lunar gravity, the high compliance chest is compressed only 3.2 cm by 93 kg, 120 kg being required for 3.8 cm. In Martian gravity, on the mean chest, 93 kg compresses 3.6 cm; 99 kg is required for 3.8 cm. On Mars, the high compliance chest is compressed 4.8 cm with 76 kg, 5.5 cm with 93 kg, with 52 kg required for 3.8 cm.

    The microgravity environment presents several challenges for delivering effective cardiopulmonary resuscitation (CPR). Chest compressions must be driven by muscular force rather than by the weight of the rescuer's upper torso. Airway stabilization is influenced by the neutral body posture. Rescuers will consist of crew members of varying sizes and degrees of physical deconditioning from space flight. Several methods of CPR designed to accommodate these factors were tested in the one G environment, in parabolic flight, and on a recent shuttle flight. Methods: Utilizing study participants of varying sizes, different techniques of CPR delivery were evaluated using a recording CPR manikin to assess adequacy of compressive force and frequency. Under conditions of parabolic flight, methods tested included conventional positioning of rescuer and victim, free floating 'Heimlich type' compressions, straddling the patient with active and passive restraints, and utilizing a mechanical cardiac compression assist device (CCAD). Multiple restrain systems and ventilation methods were also assessed. Results: Delivery of effective CPR was possible in all configurations tested. Reliance on muscular force alone was quickly fatiguing to the rescuer. Effectiveness of CPR was dependent on technique, adequate restraint of the rescuer and patient, and rescuer size and preference. Free floating CPR was adequate but rapidly fatiguing. The CCAD was able to provide adequate compressive force but positioning was problematic. Conclusions: Delivery of effective CPR in microgravity will be dependent on adequate resuer and patient restraint, technique, and rescuer size and preference. Free floating CPR may be employed as a stop gap method until patient restraint is available. Development of an adequate CCAD would be desirable to compensate for the effects of deconditioning.

    The alleviation of brain injury is a key issue following cardiopulmonary resuscitation (CPR). Hydrogen sulfide (H2S) is hypothesized to be involved in the pathophysiological process of ischemia-reperfusion injury, and exerts a protective effect on neurons. The aim of the present study was to investigate the effects of H2S on neural functions following cardiac arrest (CA) in rats. A total of 60 rats were allocated at random into three groups. CA was induced to establish the model and CPR was performed after 6 min. Subsequently, sodium hydrosulfide (NaHS), hydroxylamine or saline was administered to the rats. Serum levels of H2S, neuron-specific enolase (NSE) and S100β were determined following CPR. In addition, neurological deficit scoring (NDS), the beam walking test (BWT), prehensile traction test and Morris water maze experiment were conducted. Neuronal apoptosis rates were detected in the hippocampal region following sacrifice. After CPR, as the H2S levels increased or decreased, the serum NSE and S100β concentrations decreased or increased, respectively (P<0.0w. The NDS results of the NaHS group were improved compared with those of the hydroxylamine group at 24 h after CPR (P<0.05). In the Morris water maze experiment, BWT and prehensile traction test the animals in the NaHS group performed best and rats in the hydroxylamine group performed worst. At day 7, the apoptotic index and the expression of caspase-3 were reduced in the hippocampal CA1 region, while the expression of Bcl-2 increased in the NaHS group; and results of the hydroxylamine group were in contrast. Therefore, the results of the present study indicate that H2S is able to improve neural function in rats following CPR.

    Abstract Following a chemical, biological, radiation, and nuclear incident, prompt cardiopulmonary resuscitation (CPR) procedure is essential for patients who suffer cardiac arrest. But CPR when wearing personal protection equipment (PPE) before decontamination becomes a challenge for healthcare workers (HCW). Although previous studies have assessed the impact of PPE on airway management, there is little research available regarding the quality of chest compression (CC) when wearing PPE. A present randomized cross-over simulation study was designed to evaluate the effect of PPE on CC performance using mannequins. The study was set in one university medical center in the China. Forty anesthesia residents participated in this randomized cross-over study. Each participant performed 2 min of CC on a manikin with and without PPE, respectively. Participants were randomized into 2 groups that either performed CC with PPE first, followed by a trial without PPE after a 180-min rest, or vice versa. CPR recording technology was used to objectively quantify the quality of CC. Additionally, participants’ physiological parameters and subjective fatigue score values were recorded. With the use of PPE, a significant decrease of the percentage of effective compressions (41.3 ± 17.1% with PPE vs 67.5 ± 15.6% without PPE, P < 0.001) and the percentage of adequate compressions (67.7 ± 18.9% with PPE vs 80.7 ± 15.5% without PPE, P < 0.001) were observed. Furthermore, the increases in heart rate, mean arterial pressure, and subjective fatigue score values were more obvious with the use of PPE (all P < 0.01). We found significant deterioration of CC performance in HCW with the use of a level-C PPE, which may be a disadvantage for enhancing survival of cardiac arrest. PMID:27057878

    The adequacy of initial ventilation in 21 preterm babies (25-36 weeks' gestation), who required endotracheal intubation and positive pressure ventilation, were studied. Pressure and flow were measured at the proximal end of the endotracheal intubation tube and expiratory volume calculated from the flow trace. The results were compared with those from a group of 26 term infants who also required resuscitation. Five of 21 preterm babies (24%) had adequate tidal ventilation with the first inflation. This rose to seven of 21 (33%) by the third inflation. This was significantly less than the results in the term infants (chi 2 = 4.38 p less than 0.05). Respiratory reflex responses to resuscitation were seen in 41% of inflations in preterm and 56% of inflations in term infants. There was a significant correlation between reflex activity and adequate ventilation in the preterm group (chi 2 = 11.83, p less than 0.001) but not in the term group (chi 2 = 0.212, p = NS). No correlation was seen between initial ventilation and outcome.

    Objectives To examine the effectiveness of a “cardiopulmonary resuscitation song” in improving the basic life support skills of secondary school students. Methods This pre-test/post-test control design study enrolled secondary school students from two middle schools randomly chosen in Córdoba, Andalucia, Spain. The study included 608 teenagers. A random sample of 87 students in the intervention group and 35 in the control group, aged 12-14 years were selected. The intervention included a cardiopulmonary resuscitation song and video. A questionnaire was conducted at three-time points: pre-intervention, one month and eight months post-intervention. Results On global knowledge of cardiopulmonary resuscitation, there were no significant differences between the intervention group and the control group in the trial pre-intervention and at the month post-intervention. However, at 8 months there were significant differences with a p-value = 0.000 (intervention group, 95% CI: 6.39 to 7.13 vs. control group, 95% CI: 4.75 to 5.92), (F (1,120)=16.644, p= 0.000). In addition, significant differences about students’ basic life support knowledge about chest compressions at eight months post-intervention (F(1,120)=15.561, p=0.000) were found. Conclusions Our study showed that incorporating the song component in the cardiopulmonary resuscitation teaching increased its effectiveness and the ability to remember the cardiopulmonary resuscitation algorithm. Our study highlights the need for different methods in the cardiopulmonary resuscitation teaching to facilitate knowledge retention and increase the number of positive outcomes after sudden cardiac arrest.

    Background: Insufficient knowledge of the risks and complications of cardiopulmonary resuscitation (CPR) may be an obstructive factor for CPR, however, particularly for patients who are not clearly suffering out of hospital cardiopulmonary arrest (OH-CPA). The object of this study was to clarify the potential complication, the safety of bystander CPR in such cases. Materials and Methods: This study was a population-based observational case series. To be enrolled, patients had to have undergone CPR with chest compressions performed by lay persons, had to be confirmed not to have suffered OHCPA. Complications of bystander CPR were identified from the patients’ medical records and included rib fracture, lung injury, abdominal organ injury, and chest and/or abdominal pain requiring analgesics. In our emergency department, one doctor gathered information while others performed X-ray and blood examinations, electrocardiograms, and chest and abdominal ultrasonography. Results: A total of 26 cases were the subjects. The mean duration of bystander CPR was 6.5 minutes (ranging from 1 to 26). Nine patients died of a causative pathological condition and pneumonia, and the remaining 17 survived to discharge. Three patients suffered from complications (tracheal bleeding, minor gastric mucosal laceration, and chest pain), all of which were minimal and easily treated. No case required special examination or treatment for the complication itself. Conclusion: The risk and frequency of complications due to bystander CPR is thought to be very low. It is reasonable to perform immediate CPR for unconscious victims with inadequate respiration, and to help bystanders perform CPR using the T-CPR system. PMID:22416146

  17. Case report. Successful use of tenecteplase in massive pulmonary embolism with cardiopulmonary resuscitation immediately following tracheostomy.

    The use of thrombolytics for the treatment of massive pulmonary embolism with cardiopulmonary resuscitation is being controversially discussed. This is one of the first reports on the successful use of tenecteplase in a 59-year-old man who survived a massive pulmonary embolism after tracheostomy followed by a 30-minute cardiopulmonary resuscitation without cerebral damage. In such a dramatic clinical event, the immediate and simple use of this modern thrombolytic appears to be a justifiable last-resort treatment option until controlled studies in sufficiently sized patient populations will have proven or refuted its efficacy and safety.

    Background: The participation of pharmacists on cardiopulmonary resuscitation (CPR) teams has been associated with improvements in patient outcomes secondary to lower rates of adverse drug events and higher rates of compliance with guidelines for advanced cardiac life support (ACLS). The degree to which Canadian pharmacists participate on CPR teams and the services they provide have not previously been assessed. Objectives: To measure the frequency of pharmacists’ involvement on CPR teams in Canadian health care delivery organizations, to characterize the services provided by these pharmacists, to identify positive predictors of participation, and, for health care delivery organizations without pharmacists on CPR teams, to determine the reasons for the lack of involvement. Methods: An electronic survey was distributed to key informants in Canadian health care delivery organizations. The survey consisted of questions about characteristics of the health care delivery organizations, pharmacists’ participation and role on the CPR team, training, and barriers to implementation. The primary outcome was the percentage of health care delivery organizations with pharmacists participating on CPR teams in at least one centre within the organization. The secondary outcomes were pharmacists’ activities, training, and reasons for not participating on CPR teams. Results: Forty-three of 99 key informants responded to the survey. Twenty-nine respondents (67%) indicated that their organization had a CPR team, and 10 (23%) indicated participation by pharmacists on a CPR team. Roles reported to be performed by pharmacists during CPR events were provision of drug information, preparation and administration of medications, record-keeping, and chest compressions. Training for these pharmacists was variable: ACLS training for 4 (40%) of the 10 organizations with pharmacist participation, in-house training for 3 (30%), and no training for 2 (20%); one respondent (10%) did not report

  2. Echocardiography for patients undergoing extracorporeal cardiopulmonary resuscitation: a primer for intensive care physicians.

    Echocardiography is an invaluable tool in the management of patients with extracorporeal cardiopulmonary resuscitation (ECPR) and subsequent extracorporeal membrane oxygenation (ECMO) support and weaning. At the very beginning, echocardiography can identify the etiology of cardiac arrest, such as massive pulmonary embolism and cardiac tamponade. Eliminating these culprits saves life and may avoid the initiation of extracorporeal cardiopulmonary resuscitation. If the underlying causes are not identified or intrinsic to the heart (e.g., such as those caused by cardiomyopathy and myocarditis), conventional cardiopulmonary resuscitation (CCPR) will continue to maintain cardiac output. The quality of CCPR can be monitored, and if cardiac output cannot be maintained, early institution of extracorporeal cardiopulmonary resuscitation may be reasonable. Cannulation is sometimes challenging for extracorporeal cardiopulmonary resuscitation patients. Fortunately, with the help of ultrasonography procedures including localization of vessels, selecting a cannula of appropriate size and confirmation of catheter tip may become easy under sophisticated hand. Monitoring of cardiac function and complications during extracorporeal membrane oxygenation support can be done with echocardiography. However, the cardiac parameters should be interpreted with understanding of hemodynamic configuration of extracorporeal membrane oxygenation. Thrombus and blood stasis can be identified with ultrasound, which may prompt mechanical and pharmacological interventions. The final step is extracorporeal membrane oxygenation weaning. A number of studies investigated the accuracy of some echocardiographic parameters in predicting success rate and demonstrated promising results. Parameters and threshold for successful weaning include aortic VTI ≥ 10 cm, LVEF > 20-25%, and lateral mitral annulus peak systolic velocity >6 cm/s. However, the effectiveness of echocardiography in ECPR patients

    Delayed responses during cardiac arrest are common. Timely interventions during cardiac arrest have a direct impact on patient survival. Integration of technology in nursing education is crucial to enhance teaching effectiveness. The goal of this study was to investigate the effect of animation on nursing students' response time to cardiac arrest, including initiation of timely chest compression. Nursing students were randomized into experimental and control groups prior to practicing in a high-fidelity simulation laboratory. The experimental group was educated, by discussion and animation, about the importance of starting cardiopulmonary resuscitation upon recognizing an unresponsive patient. Afterward, a discussion session allowed students in the experimental group to gain more in-depth knowledge about the most recent changes in the cardiac resuscitation guidelines from the American Heart Association. A linear mixed model was run to investigate differences in time of response between the experimental and control groups while controlling for differences in those with additional degrees, prior code experience, and basic life support certification. The experimental group had a faster response time compared with the control group and initiated timely cardiopulmonary resuscitation upon recognition of deteriorating conditions (P < .0001). The results demonstrated the efficacy of combined teaching modalities for timely cardiopulmonary resuscitation. Providing opportunities for repetitious practice when a patient's condition is deteriorating is crucial for teaching safe practice.

    The greatest potential for survival of sudden cardiac arrest can be achieved only by providing early intervention using evidence-based therapies that have been studied over time. Emergency cardiac care and the 2000 advanced cardiac life support guidelines encompass all therapies that have been shown to improve outcomes in patients who experience life-threatening events that involve the cardiovascular, cerebrovascular, and pulmonary systems. Early recognition of warning signs, activation of emergency medical systems within the community, basic cardiopulmonary resuscitation, early defibrillation, airway management, and intravenous medication administration are key factors in improving resuscitation outcomes.

  7. New perspectives of nitric oxide donors in cardiac arrest and cardiopulmonary resuscitation treatment.

    PubMed

    Kruzliak, Peter; Pechanova, Olga; Kara, Tomas

    2014-05-01

    Nitric oxide (NO) is often used to treat heart failure accompanied with pulmonary edema. According to present knowledge, however, NO donors are contraindicated when systolic blood pressure is less than 90 mmHg. Based on recent findings and our own clinical experience, we formulated a hypothesis about the new breakthrough complex lifesaving effects of NO donors in patients with cardiac arrest and cardiopulmonary resuscitation therapy. It includes a direct hemodynamic effect of NO donors mediated through vasodilation of coronary arteries in cooperation with improvement of cardiac function and cardiac output through reversible inhibition of mitochondrial complex I and mitochondrial NO synthase, followed by reduction in reactive oxygen species and correction of myocardial stunning. Simultaneously, an increase in vascular sensitivity to sympathetic stimulation could lead to an increase in diastolic blood pressure. Confirmation of this hypothesis in clinical practice would mean a milestone in the treatment for cardiac arrest and cardiopulmonary resuscitation.

    We wanted to identify incidents that led or could have led to patient harm during prehospital cardiopulmonary resuscitation. A nationwide anonymous and Internet-based critical incident reporting system gave the data. During a 4-year period we received 548 reports of which 74 occurred during cardiopulmonary resuscitation. Human error was responsible for 85% of the incidents, whereas equipment failure contributed to 15% of the reports. Equipment failure was considered to be preventable in 61% of all the cases, whereas incidents because of human error could have been prevented in almost all the cases. In most cases, prevention can be accomplished by simple strategies with the Poka-Yoke technique. Insufficient training of emergency medical service physicians in Germany requires special attention. The critical incident reports raise concerns regarding the level of expertize provided by emergency medical service doctors.

    2016-02-02

    A 64-year-old man with a history of ascending aortic surgery and pulmonary embolus presented with shortness of breath. He rapidly decompensated, prompting intubation, after which he lost pulses. Manual resuscitation was initiated immediately, with subsequent use of a LUCAS-2 mechanical compression device. The patient was given bolus thrombolytic therapy and regained pulses after 7 min of CPR. Compressions were reinitiated with the LUCAS-2 twice more during resuscitation over the subsequent hour for brief episodes of PEA. After confirmation of massive pulmonary embolism on CT, the patient underwent interventional radiology-guided ultrasonic catheter placement with local thrombolytic therapy and experienced immediate improvement in oxygenation. He later developed abdominal compartment syndrome, despite cessation of thrombolytic and anticoagulation therapy. Bedside exploratory abdominal laparotomy revealed a ruptured subcapsular haematoma of the liver. The patient's haemodynamics improved following surgery and he was extubated 11 days postarrest with intact neurological function.

    In a 12-month prospective survey of CPR (cardiopulmonary resuscitation), 32 out of 192 patients (16.6%) survived to go home. This is a clear improvement compared with 7 years previously. This is attributed to better training in the use and management of CPR and more widespread availability of defibrillators. Certain patients could not be resuscitated--those with electromechanical dissociation, carcinoma, or multiple pathology. Age by itself was not a bar to resuscitation. There is still a high rate of inappropriate calls, often because of uncertainty by nurses about the use of CPR. This could be improved with clearer guidelines in hospitals about the value of CPR in selected patients. PMID:2152462

    Cardiopulmonary resuscitation manikins are used for training personnel in performing cardiopulmonary resuscitation. State-of-the-art cardiopulmonary resuscitation manikins are still anatomically and physiologically low-fidelity designs. The aim of this research was to design a manikin that offers high anatomical and physiological fidelity and has a cardiac and respiratory system along with integrated flow sensors to monitor cardiac output and air displacement in response to cardiopulmonary resuscitation. This manikin was designed in accordance with anatomical dimensions using a polyoxymethylene rib cage connected to a vertebral column from an anatomical female model. The respiratory system was composed of silicon-coated memory foam mimicking lungs, a polyvinylchloride bronchus and a latex trachea. The cardiovascular system was composed of two sets of latex tubing representing the pulmonary and aortic arteries which were connected to latex balloons mimicking the ventricles and lumped abdominal volumes, respectively. These balloons were filled with Life/form simulation blood and placed inside polyether foam. The respiratory and cardiovascular systems were equipped with flow sensors to gather data in response to chest compressions. Three non-medical professionals performed chest compressions on this manikin yielding data corresponding to force-displacement while the flow sensors provided feedback. The force-displacement tests on this manikin show a desirable nonlinear behaviour mimicking chest compressions during cardiopulmonary resuscitation in humans. In addition, the flow sensors provide valuable data on the internal effects of cardiopulmonary resuscitation. In conclusion, scientifically designed and anatomically high-fidelity designs of cardiopulmonary resuscitation manikins that embed flow sensors can improve physiological fidelity and provide useful feedback data.

    2004-01-01

    INTRODUCTION: The International Space Station will need to be as capable as possible in providing Advanced Cardiac Life Support (ACLS) and cardiopulmonary resuscitation (CPR). Previous studies with manikins in parabolic microgravity (0 G) have shown that delivering CPR in microgravity is difficult. End tidal carbon dioxide (PetCO2) has been previously shown to be an effective non-invasive tool for estimating cardiac output during cardiopulmonary resuscitation. Animal models have shown that this diagnostic adjunct can be used as a predictor of survival when PetCO2 values are maintained above 25% of pre-arrest values. METHODS: Eleven anesthetized Yorkshire swine were flown in microgravity during parabolic flight. Physiologic parameters, including PetCO2, were monitored. Standard ACLS protocols were used to resuscitate these models after chemical induction of cardiac arrest. Chest compressions were administered using conventional body positioning with waist restraint and unconventional vertical-inverted body positioning. RESULTS: PetCO2 values were maintained above 25% of both 1-G and O-G pre-arrest values in the microgravity environment (33% +/- 3 and 41 +/- 3). No significant difference between 1-G CPR and O-G CPR was found in these animal models. Effective CPR was delivered in both body positions although conventional body positioning was found to be quickly fatiguing as compared with the vertical-inverted. CONCLUSIONS: Cardiopulmonary resuscitation can be effectively administered in microgravity (0 G). Validation of this model has demonstrated that PetCO2 levels were maintained above a level previously reported to be predictive of survival. The unconventional vertical-inverted position provided effective CPR and was less fatiguing as compared with the conventional body position with waist restraints.

    Cardiac arrest occurs in approximately 1:12,000 parturients. Among nonpregnant patients who have in-hospital cardiac arrest, those whose spontaneous circulation does not return within 15 to 20 minutes have a high risk of death and disability, so life support efforts are generally stopped after this period. However, among parturients, witnessed in-hospital arrest is often reversible and has a better prognosis. We describe a successful clinical outcome after maternal cardiac arrest and 55 minutes of advanced cardiac life support. This case underscores the importance of high-quality cardiopulmonary resuscitation and raises questions about the appropriate duration of resuscitation efforts in otherwise healthy young mothers with a potentially reversible cause of arrest.

    BACKGROUND: There are several reasons why resuscitation measures may lead to inferior results: difficulties in team building, delayed realization of the emergency and interruption of chest compression. This study investigated the outcome of a new form of in-hospital cardiopulmonary resuscitation (CPR) training with special focus on changes in self-assurance of potential helpers when faced with emergency situations. METHODS: Following a 12-month period of CPR training, questionnaires were distributed to participants and non-participants. Those non-participants who intended to undergo the training at a later date served as control group. RESULTS: The study showed that participants experienced a significant improvement in self-assurance, compared with their remembered self-assurance before the training. Their self-assurance also was significantly greater than that of the control group of non-participants. CONCLUSION: Short lessons in CPR have an impact on the self-assurance of medical and non-medical personnel. PMID:27942341

    Background: After CPR, the follow-up of survival rate and caused complications are the most important practices of the medical group. This study was performed aimed at determining the follow-up results after CPR in patients of university hospitals in Kermanshah in 2014. Methods: In this prospective study, 320 samples were examined. A purposive sampling method was used, and data was collected using a researcher-made information form with content and face validity and reliability of r= 0.79. Data was analyzed with STATA9 software and statistical tests, including calculation of the success rate, relative risk (RR), chi-square and Fisher at significance level of P < 0.05. Results: The initial success rate of cardiopulmonary resuscitation was equal to 15.3%, while the ultimate success rate (discharged alive from the hospital) was as 10.6%. The six-month success rate after resuscitation was 8.78% than those who were discharged alive. There were no significant statistical differences between different age groups regarding the initial success rate of resuscitation (P = 0.14), and the initial resuscitation success rate was higher in patients in morning shift (P = 0.02). Conclusion: By the results of study, it is recommended to increase the medical - nursing knowledge and techniques for personnel in the evening and night shifts. Also, an appropriate dissemination of health care staff in working shifts should be done to increase the success rate of CPR procedure. PMID:25560341

    Despite significant advances in perinatal medicine, the management of extremely preterm infants in the delivery room remains a challenge. There is an increasing evidence for improved outcomes regarding the resuscitation and stabilisation of extremely preterm infants but there is a lack of evidence in the periviable (gestational age 23-25 wk) preterm subgroup. Presence of an experienced team during the delivery of extremely preterm infant to improve outcome is reviewed. Adaptation from foetal to neonatal cardiorespiratory haemodynamics is dependent on establishing an optimal functional residual capacity in the extremely preterm infants, thus enabling adequate gas exchange. There is sufficient evidence for a gentle approach to stabilisation of these fragile infants in the delivery room. Evidence for antenatal steroids especially in the periviable infants, delayed cord clamping, strategies to establish optimal functional residual capacity, importance of temperature control and oxygenation in delivery room in extremely premature infants is reviewed in this article.

    Empirical evidence suggests that family presence during cardiopulmonary resuscitation (CPR) has beneficial effects. Although many American professional organizations have endorsed the idea of family presence, there is less formal support in Europe. In addition, the attitude of nurses from Anglo-Saxon countries, such as United Kingdom and Ireland, is more positive toward family presence than the attitude of nurses of mainland Europe. In order to support existing guidelines and to stimulate health care organizations to develop a formal policy with respect to family witnessed CPR, 3 important European nursing organizations have recently developed a joint position statement.

In this questionnaire survey, G2010 AHA-BLS Healthcare Provider Course participants answered four questions about CPR caveats which should be considered during pregnancy. The correct answer ratio is generally low among the four questions. Special situation explanation addition such as left uterine displacement in the AHA-BLS healthcare provider course may be needed for the empowerment of knowledge about cardiopulmonary resuscitation during pregnancy.

    Objective Extracorporeal cardiopulmonary resuscitation (ECPR) may be considered as a rescue therapy for patients with refractory cardiac arrest. Identifying patients who might benefit from this potential life-saving procedure is crucial for implementation of ECPR. The objective of this study was to estimate the number of patients who fulfilled a hypothetical set of ECPR criteria and to evaluate the outcome of ECPR candidates treated with conventional cardiopulmonary resuscitation. Methods We performed an observational study using data from a prospective registry of consecutive adults (≥18 years) with non-traumatic out-of-hospital cardiac arrest in a tertiary hospital between January 2011 and December 2015. We developed a hypothetical set of ECPR criteria including age ≤75 years, witnessed cardiac arrest, no-flow time ≤5 minutes, low-flow time ≤30 minutes, refractory arrest at emergency department >10 minutes, and no exclusion criteria. The primary endpoint was the proportion of good neurologic outcome of ECPR-eligible patients. Results Of 568 out-of-hospital cardiac arrest cases, 60 cases (10.6%) fulfilled our ECPR criteria. ECPR was performed for 10 of 60 ECPR-eligible patients (16.7%). Three of the 10 patients with ECPR (30.0%), but only 2 of the other 50 patients without ECPR (4.0%) had a good neurologic outcome at 1 month. Conclusion ECPR implementation might be a rescue option for increasing the probability of survival in potentially hopeless but ECPR-eligible patients. PMID:27752631

    Outcomes from cardiopulmonary resuscitation (CPR) remain distressingly poor. Overuse of CPR is attributable to unrealistic expectations, unintended consequences of existing policies and failure to honour patient refusal of CPR. We analyzed the CPR outcomes literature using the bioethical principles of beneficence, non-maleficence, autonomy and justice and developed a proposal for selective use of CPR. Beneficence supports use of CPR when most effective. Non-maleficence argues against performing CPR when the outcomes are harmful or usage inappropriate. Additionally, policies which usurp good clinical judgment and moral responsibility, thereby contributing to inappropriate CPR usage, should be considered maleficent. Autonomy restricts CPR use when refused but cannot create a right to CPR. Justice requires that we define which medical interventions contribute sufficiently to health and happiness that they should be made universally available. This ordering is necessary whether one believes in the utilitarian standard or wishes medical care to be universally available on fairness grounds. Low-yield CPR fails justice criteria. Cardiopulmonary resuscitation should be performed when justified by the extensive outcomes literature; not performed when not desired by the patient or not indicated; and performed infrequently when relatively contraindicated.

    In an effort to determine the actual conduct of neonatal resuscitation and the errors that may be occurring during this process, we developed a method of video recording neonatal resuscitations as an ongoing quality assurance project. We initiated video recordings of resuscitations using simple video recorders attached to an overhead warmer and reviewed the resultant tapes during biweekly quality improvement meetings. We also added the continuous recording of analog information such as heart rate, oximeter values, fraction of inspired oxygen and airway pressure. We subsequently developed a checklist that includes a preresuscitation briefing and a postresuscitation debriefing, all of which are reviewed at the same time as the video recording. We have examined the use of oxygen in the very preterm infant, the effectiveness of bag and mask ventilation, including the detection of airway obstruction during such ventilation, intubation in the delivery area and environment. In addition, we have trained our teams and leaders using Crew Resource Management and focused on improved communication. The availability of a dedicated room for resuscitation allows an increased ambient environment and the ability to provide a user-friendly setting similar to the neonatal intensive care unit to optimize performance. There are numerous opportunities for improving team and leader performance and outcomes following neonatal resuscitation. Further prospective studies are required to evaluate specific interventions.

    Advanced cardiovascular life support guidelines exist, yet there are variations in clinical practice. Our study aims to describe the utilization of medications during resuscitation from in-hospital cardiopulmonary arrest. A retrospective review of patients who suffered a cardiopulmonary arrest from May 2008 to June 2014 was performed. Clinical and resuscitation data, including timing and dose of medications used, were extracted from the electronic medical record and comparisons made. A total of 94 patients were included in the study. Patients were divided into different groups based on the medication combination used during resuscitation: (1) epinephrine; (2) epinephrine and bicarbonate; (3) epinephrine, bicarbonate, and calcium; (4) epinephrine, bicarbonate, and epinephrine drip; and (5) epinephrine, bicarbonate, calcium, and epinephrine drip. No difference in baseline demographics or clinical data was present, apart from history of dementia and the use of calcium channel blockers. The number of medications given was correlated with resuscitation duration (Spearman's rank correlation = 0.50, p <0.001). The proportion of patients who died during the arrest was 12.5% in those who received epinephrine alone, 30.0% in those who received only epinephrine and bicarbonate, and 46.7% to 57.9% in the remaining groups. Patients receiving only epinephrine had shorter resuscitation durations compared to that of the other groups (p <0.001) and improved survival (p = 0.003). In conclusion, providers frequently use nonguideline medications in resuscitation efforts for in-hospital cardiopulmonary arrests. Increased duration and mortality rates were found in those resuscitations compared with epinephrine alone, likely due to the longer resuscitation duration in the former groups.

    Cardiopulmonary resuscitation in patients with severe sepsis and septic shock is challenging and usually unsuccessful. The aim of the present study is to describe our swine model of cardiac arrest and resuscitation in severe sepsis and septic shock. In this prospective randomized animal study, 10 healthy female Landrace-Large White pigs with an average weight of 20 ± 1 kg (aged 19 - 21 weeks) were the study subjects. Septicemia was induced by an intravenous infusion of a bolus of 20-mL bacterial suspension in 2 min, followed by a continuous infusion during the rest of the experiment. After septic shock was confirmed, the animals were left untreated until cardiac arrest occurred. All animals developed pulseless electrical activity between the fifth and sixth hours of septicemia, whereas five (50%) of 10 animals were successfully resuscitated. Coronary perfusion pressure was statistically significantly different between surviving and nonsurviving animals. We found a statistically significant correlation between mean arterial pressure and unsuccessful resuscitation (P = 0.046), whereas there was no difference in end-tidal carbon dioxide (23.05 ± 1.73 vs. 23.56 ± 1.70; P = 0.735) between animals with return of spontaneous circulation and nonsurviving animals. During the 45-min postresuscitation monitoring, we noted a significant decrease in hemodynamic parameters, although oxygenation indices and lactate clearance were constantly increased (P = 0.001). This successful basic swine model was for the first time developed and may prove extremely useful in future studies on the periarrest period in severe sepsis and septic shock.

    Early defibrillation in cardiopulmonary resuscitation (CPR) receives increasing emphasis on its priority and rapidity. This is an experience report about the implementation of a training program in CPR using a defibrillator in a private university. The training program in basic CPR maneuvers was based on global guidelines, including a theorical course with practical demonstration of CPR maneuvers with the defibrillator, individual practical training and theoretical and practical assessments. About the performance of students in the practical assessment the mean scores obtained by students in the first stage of the course was 26.4 points, while in the second stage the mean was 252.8 points, in the theoretical assessment the mean in the first stage was 3.06 points and in the second 9.0 points. The implementation of programs like this contribute to the effective acquisition of knowledge (theory) and skill (pratice) for the care of CPR victims.

    Sudden cardiac arrest is one of the critical clinical syndromes in emergency situations. A cardiopulmonary resuscitation (CPR) is a necessary curing means for those patients with sudden cardiac arrest. In order to simulate effectively the hemodynamic effects of human under AEI-CPR, which is active compression-decompression CPR coupled with enhanced external counter-pulsation and inspiratory impedance threshold valve, and research physiological parameters of each part of lower limbs in more detail, a CPR simulation model established by Babbs was refined. The part of lower limbs was divided into iliac, thigh and calf, which had 15 physiological parameters. Then, these 15 physiological parameters based on genetic algorithm were optimized, and ideal simulation results were obtained finally.

    Effective cardiopulmonary resuscitation (CPR) skills are essential for better patient survival, but whether these skills are associated with knowledge of and self-efficacy in CPR is not well known. The purpose of this study was to assess the quality of CPR skills and identify the association of the psychomotor skills with knowledge and self-efficacy at the time of CPR skills training. A convenience sample of 124 nursing students participated in a one-group posttest-only study. The quality of CPR psychomotor skills, as assessed by structured observation using a manikin, was suboptimal. Nursing students who performed correct chest compression skills reported higher self-efficacy, but there was no association between CPR psychomotor skills and total knowledge. Rigorous skills training sessions with more objective feedback on performance and individual coaching are warranted to enable mastery learning and self-efficacy.

    Cardiac arrest (CA) patients can experience neurological sequelae or even death after successful cardiopulmonary resuscitation (CPR) due to cerebral hypoxia- and ischemia-reperfusion-mediated brain injury. Thus, it is important to perform early prognostic evaluations in CA patients. Electroencephalography (EEG) is an important tool for determining the prognosis of hypoxic-ischemic encephalopathy due to its real-time measurement of brain function. Based on EEG, burst suppression, a burst suppression ratio >0.239, periodic discharges, status epilepticus, stimulus-induced rhythmic, periodic or ictal discharges, non-reactive EEG, and the BIS value based on quantitative EEG may be associated with the prognosis of CA after successful CPR. As measures of neural network integrity, the values of small-world characteristics of the neural network derived from EEG patterns have potential applications.

    Abstract To determine the relationship between acid–base findings, such as pH, pCO2, and serum lactate levels, obtained immediately after starting cardiopulmonary resuscitation and the return of spontaneous circulation (ROSC). A prospective observational study of adult, nontraumatic out-of-hospital cardiac arrest (OHCA) patients was conducted at an urban academic teaching institution between April 1, 2013 and March 31, 2015. Arterial blood sample for acid–base data was taken from all OHCA patients on arrival to the emergency department. Of 224 OHCA patients, 88 patients with unavailable blood samples or delayed blood sampling or ROSC within 4 minutes were excluded, leaving 136 patients for analysis. The pH in the ROSC group was significantly higher than in the non-ROSC group (6.96 vs. 6.85; P = 0.009). pCO2 and lactate levels in the ROSC group were significantly lower than those in the non-ROSC group (74.0 vs. 89.5 mmHg, P < 0.009; 11.6 vs. 13.6 mmol/L, P = 0.044, respectively). In a multivariate regression analysis, pCO2 was the only independent biochemical predictor for sustained ROSC (OR 0.979; 95% CI 0.960–0.997; P = 0.025) and pCO2 of <75 mmHg was 3.3 times more likely to achieve ROSC (OR 0.302; 95% CI 0.146–0.627; P = 0.001). pCO2 levels obtained during cardiopulmonary resuscitation on ER arrival was associated with ROSC in OHCA patients. It might be a potentially marker for reflecting the status of the ischemic insult. These preliminary results need to be confirmed in a larger population. PMID:27336894

    Semiautomated external defibrillators are widely used by prehospital emergency personnel. Some of the devices have a rhythm display and some show only text commands on the screen. To evaluate the effects on cardiopulmonary resuscitation (CPR) performance of seeing the rhythm during resuscitation, 60 fire-fighter students were randomly divided in two groups and trained to use either a defibrillator with a rhythm display or one without a display. The students in both groups formed teams of two rescuers, and their performance of CPR on a manikin was tested using a predefined rhythm sequence in a simulated cardiac arrest situation. The teams using a defibrillator with a rhythm display more often interrupted CPR for pulse checks than those who did not see the rhythm (P=0.003). The duration of CPR between rhythm analyses was shorter in the group who saw the rhythm on the screen (P=0.002). Our data suggest that seeing an organised rhythm on a monitor during CPR interferes with adherence to CPR algorithms which may have a negative influence on the performance of CPR.

    Mortality during pregnancy in a well-resourced setting is rare, but acute pulmonary embolism is one of the leading causes. We present the successful use of extracorporeal cardiopulmonary resuscitation (eCPR) in a 22-year old woman who experienced cardiopulmonary collapse following urgent caesarean section in the setting of a sub-massive pulmonary embolus. Resources and personnel to perform eCPR were not available at the maternity hospital and were recruited from an adjacent pediatric hospital. Initial care used low blood flow extracorporeal membrane oxygenation (ECMO) with pediatric ECMO circuitry, which was optimized when the team from a nearby adult cardiac hospital arrived. Following ECMO support, the patient experienced massive hemorrhage which was managed with uterotonic agents, targeted transfusion, bilateral uterine artery embolisation and abdominal re-exploration. The patient was transferred to an adult unit where she remained on ECMO for five days. She was discharged home with normal cognitive function. This case highlights the role ECMO plays in providing extracorporeal respiratory or mechanical circulatory support in a high risk obstetric patient.

    Objective The aim of this study was to evaluate the relative frequency of pediatric in-hospital CPR events occurring in intensive care units (ICUs) compared to general wards. We hypothesized that the proportion of pediatric CPR provided in ICUs versus general wards has increased over the past decade and this shift is associated with improved resuscitation outcomes. Design Prospective, observational study. Setting Total of 315 hospitals in the American Heart Association’s Get With The Guidelines-Resuscitation (GTWG-R) database. Patients Total of 5,870 pediatric cardiopulmonary resuscitation (CPR) events between January 1, 2000 and September 14, 2010. CPR events were defined as external chest compressions >1minute. Measurements and Results The primary outcome was proportion of total ICU versus general ward CPR events over time evaluated by chi square test for trend. Secondary outcome included return of spontaneous circulation (ROSC) following the CPR event. Among 5870 pediatric CPR events, 5477 (93.3%) occurred in ICUs compared to 393 (6.7%) on inpatient wards. Over time, significantly more of these CPR events occurred in the ICU compared to the wards (test for trend: p<0.01), with a prominent shift noted between 2003 and 2004 (2000-2003: 87 - 91% vs. 2004-2010: 94 - 96%). In a multivariable model controlling for within center variability and other potential confounders, ROSC increased in 2004-2010 compared with 2000-2003 (RR 1.08, 95% confidence interval: 1.03-1.13). Conclusions In-hospital pediatric CPR is much more commonly provided in ICUs vs. Wards and the proportion has increased significantly over the past decade with concomitant increases in return of spontaneous circulation.

    Background Despite several studies, there is no agreement on factors that affect survival after in-hospital cardiopulmonary resuscitation (CPR). Objectives This study aimed to evaluate the survival rate of in-hospital CPR and its related factors at Shahid Beheshti hospital in Kashan, Iran, in 2014. Patients and Methods A descriptive study was conducted on all cases of CPR performed in Kashan Shahid Beheshti hospital during a 6-month period in 2014. Through a consecutive sampling method, 250 cases of CPR were studied. A three-part researcher-made instrument was used. The outcome of CPR was documented as either survival to hospital discharge or unsuccessful (death of the patient). Chi-square test, t test, and logistic regression analysis were used to analyze the data. Results Of all CPR cases, 238 (95.2%) were unsuccessful and 12 (4.8%) survived to hospital discharge. Only 2.6% of patients who were resuscitated in medical units survived to hospital discharge, whereas this rate was 11.4% in the emergency department. Only 45 (18%) patients were defibrillated during resuscitation; in 11 patients, defibrillation was performed between 15 to 45 minutes after the initiation of CPR. The mean time from initiation of CPR to the first DC shock was 13.93 ± 8.88 minutes. Moreover, the mean duration of CPR was 35.11 ± 11.42 minutes. The survival rate was higher in the morning shift and lower during the time of shift change (9.4% vs. 0). The duration of CPR and speed of arrival of the CPR team were identified as factors that predicted the outcome of CPR. Conclusions The survival rate after in-hospital CPR was very low. The duration of CPR and the time of initiating CPR effects patients’ outcomes. These findings highlight the crucial role of an organized, skilled, well-established and timely CPR team. PMID:27218061

    Background No systematic evaluation of smartphone/mobile apps for resuscitation training and real incident support is available to date. To provide medical, usability, and additional quality criteria for the development of apps, we conducted a mixed-methods sequential evaluation combining the perspective of medical experts and end-users. Objective The study aims to assess the quality of current mobile apps for cardiopulmonary resuscitation (CPR) training and real incident support from expert as well as end-user perspective. Methods Two independent medical experts evaluated the medical content of CPR apps from the Google Play store and the Apple App store. The evaluation was based on pre-defined minimum medical content requirements according to current Basic Life Support (BLS) guidelines. In a second phase, non-medical end-users tested usability and appeal of the apps that had at least met the minimum requirements. Usability was assessed with the System Usability Scale (SUS); appeal was measured with the self-developed ReactionDeck toolkit. Results Out of 61 apps, 46 were included in the experts’ evaluation. A consolidated list of 13 apps resulted for the following layperson evaluation. The interrater reliability was substantial (kappa=.61). Layperson end-users (n=14) had a high interrater reliability (intraclass correlation 1 [ICC1]=.83, P<.001, 95% CI 0.75-0.882 and ICC2=.79, P<.001, 95% CI 0.695-0.869). Their evaluation resulted in a list of 5 recommendable apps. Conclusions Although several apps for resuscitation training and real incident support are available, very few are designed according to current BLS guidelines and offer an acceptable level of usability and hedonic quality for laypersons. The results of this study are intended to optimize the development of CPR mobile apps. The app ranking supports the informed selection of mobile apps for training situations and CPR campaigns as well as for real incident support. PMID:24647361

    Background Cardiopulmonary resuscitation (CPR) is an emergency procedure used to treat victims following cardiopulmonary arrest. Graduate health professionals at the University of Gondar Teaching Hospital manage many trauma and critically ill patients. The chance of survival after cardiopulmonary arrest may be increased with sufficient attitude and skill levels. The study aimed to assess the attitude and skill levels of graduate health professionals in performing CPR. Methods A hospital-based cross-sectional study was conducted from May 1 to 30, 2013, at the University of Gondar Teaching Hospital. The mean attitude and skill scores were compared for sex, original residence, and department of the participants using Student’s t-test and analysis of variance (Scheffe’s test). P-values <0.05 were considered to be statistically significant. Results Of the 506 graduates, 461 were included in this study with a response rate of 91.1%. The mean attitude scores of nurse, interns, health officer, midwifery, anesthesia, and psychiatric nursing graduates were 1.15 (standard deviation [SD] =1.67), 8.21 (SD =1.24), 7.2 (SD =1.49), 6.69 (SD =1.83), 8.19 (SD =1.77), and 7.29 (SD =2.01), respectively, and the mean skill scores were 2.34 (SD =1.95), 3.77 (SD =1.58), 1.18 (SD =1.52), 2.16 (SD =1.93), 3.88 (SD =1.36), and 1.21 (SD =1.77), respectively. Conclusion and recommendations Attitude and skill level of graduate health professionals with regard to CPR were insufficient. Training on CPR for graduate health professionals needs to be given emphasis. PMID:28123315

    Objective While cardiopulmonary resuscitation (CPR) chest compression fraction (CCF) is associated with out-of-hospital cardiac arrest (OHCA) outcomes, there is no standard method for the determination of CCF. We compared nine methods for calculating CCF. Methods We studied consecutive adult OHCA patients treated by Alabama Emergency Medical Services (EMS) agencies of the Resuscitation Outcomes Consortium (ROC) during Jan. 1, 2010 - Oct. 28, 2010. Paramedics used portable cardiac monitors with real-time chest compression detection technology (LifePak 12, Physio-Control, Redmond, Washington). We performed both automated CCF calculation for the entire care episode as well as manual review of CPR data in 1-minute epochs, defining CCF as the proportion of each treatment interval with active chest compressions. We compared the CCF values resulting from 9 calculation methods: 1) mean CCF for the entire patient care episode (automated calculation by manufacturer software), 2) mean CCF for first 3 minutes of patient care, 3) mean CCF for first 5 minutes, 4) mean CCF for first 10 minutes, 5) mean CCF for the entire episode except first 5 minutes, 6) mean CCF for last 5 minutes, 7) mean CCF from start to first shock, 8) mean CCF for the first half of resuscitation, 9) mean CCF for the second half of resuscitation. We compared CCF for Methods 2-9 with Method 1 using paired t-tests with a Bonferroni-adjusted p-value of 0.006 (99.5% confidence intervals). Results Among 102 adult OHCA, patient demographics were: mean age 60.3 years (SD 20.8 years), African American 56.9%, male 63.7%, and shockable ECG rhythm 23.5%. Mean CPR duration was 728 seconds (95% CI: 647-809 seconds). Mean CCF for the 9 CCF calculation methods were: 1) 0.587; 2) 0.526; 3) 0.541; 4) 0.566; 5) 0.562; 6) 0.597; 7) 0.530; 8) 0.550; 9) 0.590%. Compared with Method 1, Method 7 CCF (start to first shock) was slightly lower (−0.057; 99.5% CI: −0.100 – (−0.014)). There were no other statistically

    Cerebral metabolic alterations during cardiac arrest, cardiopulmonary resuscitation (CPR) and extracorporeal cardiopulmonary life support (ECLS) are poorly explored. Markers are needed for a more personalized resuscitation and post—resuscitation care. Aim of this study was to investigate early metabolic changes in the hippocampal CA1 region during ventricular fibrillation cardiac arrest (VF-CA) and ECLS versus conventional CPR. Male Sprague-Dawley rats (350g) underwent 8min untreated VF-CA followed by ECLS (n = 8; bloodflow 100ml/kg), mechanical CPR (n = 18; 200/min) until return of spontaneous circulation (ROSC). Shams (n = 2) were included. Glucose, glutamate and lactate/pyruvate ratio were compared between treatment groups and animals with and without ROSC. Ten animals (39%) achieved ROSC (ECLS 5/8 vs. CPR 5/18; OR 4,3;CI:0.7–25;p = 0.189). During VF-CA central nervous glucose decreased (0.32±0.1mmol/l to 0.04±0.01mmol/l; p<0.001) and showed a significant rise (0.53±0.1;p<0.001) after resuscitation. Lactate/pyruvate (L/P) ratio showed a 5fold increase (31 to 164; p<0.001; maximum 8min post ROSC). Glutamate showed a 3.5-fold increase to (2.06±1.5 to 7.12±5.1μmol/L; p<0.001) after CA. All parameters normalized after ROSC with no significant differences between ECLS and CPR. Metabolic changes during ischemia and resuscitation can be displayed by cerebral microdialysis in our VF-CA CPR and ECLS rat model. We found similar microdialysate concentrations and patterns of normalization in both resuscitation methods used. Institutional Protocol Number: GZ0064.11/3b/2011 PMID:27175905

    There is increasing evidence that ischemic brain injury is modulated by peripheral signaling. Peripheral organ ischemia can induce brain inflammation and injury. We therefore hypothesized that brain injury sustained after cardiac arrest (CA) is influenced by peripheral organ ischemia and that peripheral organ protection can reduce brain injury after CA and cardiopulmonary resuscitation (CPR). Male C57Bl/6 mice were subjected to CA/CPR. Brain temperature was maintained at 37.5°C ± 0.0°C in all animals. Body temperature was maintained at 35.1°C ± 0.1°C (normothermia) or 28.8°C ± 1.5°C (extracranial hypothermia [ExHy]) during CA. Body temperature after resuscitation was maintained at 35°C in all animals. Behavioral testing was performed at 1, 3, 5, and 7 days after CA/CPR. Either 3 or 7 days after CA/CPR, blood was analyzed for serum urea nitrogen, creatinine, alanine aminotransferase, aspartate aminotransferase, and interleukin-1β; mice were euthanized; and brains were sectioned. CA/CPR caused peripheral organ and brain injury. ExHy animals experienced transient reduction in brain temperature after resuscitation (2.1°C ± 0.5°C for 4 minutes). Surprisingly, ExHy did not change peripheral organ damage. In contrast, hippocampal injury was reduced at 3 days after CA/CPR in ExHy animals (22.4% ± 6.2% vs. 45.7% ± 9.1%, p=0.04, n=15/group). This study has two main findings. Hypothermia limited to CA does not reduce peripheral organ injury. This unexpected finding suggests that after brief ischemia, such as during CA/CPR, signaling or events after reperfusion may be more injurious than those during the ischemic period. Second, peripheral organ hypothermia during CA reduces hippocampal injury independent of peripheral organ protection. While it is possible that this protection is due to subtle differences in brain temperature during early reperfusion, we speculate that additional mechanisms may be involved. Our findings add to the growing understanding of

    Background Mechanical ventilation via automated in-hospital ventilators is quite common during cardiopulmonary resuscitation. It is not known whether different inspiratory triggering sensitivity settings of ordinary ventilators have different effects on actual ventilation, gas exchange and hemodynamics during resuscitation. Methods 18 pigs enrolled in this study were anaesthetized and intubated. Continuous chest compressions and mechanical ventilation (volume-controlled mode, 100% O2, respiratory rate 10/min, and tidal volumes 10ml/kg) were performed after 3 minutes of ventricular fibrillation. Group trig-4, trig-10 and trig-20 (six pigs each) were characterized by triggering sensitivities of 4, 10 and 20 (cmH2O for pressure-triggering and L/min for flow-triggering), respectively. Additionally, each pig in each group was mechanically ventilated using three types of inspiratory triggering (pressure-triggering, flow-triggering and turned-off triggering) of 5 minutes duration each, and each animal matched with one of six random assortments of the three different triggering settings. Blood gas samples, respiratory and hemodynamic parameters for each period were all collected and analyzed. Results In each group, significantly lower actual respiratory rate, minute ventilation volume, mean airway pressure, arterial pH, PaO2, and higher end-tidal carbon dioxide, aortic blood pressure, coronary perfusion pressure, PaCO2 and venous oxygen saturation were observed in the ventilation periods with a turned-off triggering setting compared to those with pressure- or flow- triggering (all P<0.05), except when compared with pressure-triggering of 20 cmH2O (respiratory rate 10.5[10/11.3]/min vs 12.5[10.8/13.3]/min, P = 0.07; coronary perfusion pressure 30.3[24.5/31.6] mmHg vs 27.4[23.7/29] mmHg, P = 0.173; venous oxygen saturation 46.5[32/56.8]% vs 41.5[33.5/48.5]%, P = 0.575).

    We evaluated the association of body temperature patterns with neurological outcomes after extracorporeal cardiopulmonary resuscitation (ECPR). Between December 2013 and December 2015, we enrolled 48 patients with cardiac arrest who survived for at least 24 hours after ECPR. Based on their body temperature patterns and the intention to control fever, we divided the patients into those in whom fever was actively controlled (N = 25), those with normothermia (N = 17), and those with unintended hypothermia (N = 6). The primary outcome was the Cerebral Performance Categories (CPC) scale at discharge. Of the 48 ECPR patients, 23 patients (47.9%) had good neurological outcomes (CPC 1 and 2) and 27 patients (56.3%) survived to discharge. The normothermia group showed a pattern of higher temperatures compared with the other groups during 48 hours after ECPR. Not only poor neurological outcomes but also intensive care unit (ICU) mortality occurred more often in the unintended hypothermia group than in the other two groups, regardless of the fever control strategy (p = 0.023 and p = 0.002, respectively). There were no differences in neurological outcomes and ICU mortality between the actively controlled fever group and the normothermia group (p = 0.845 and p = 0.616, respectively). Unintentionally sustained hypothermia may be associated with poor neurological outcomes after ECPR. These findings suggest that patients who are unable to generate a fever following ECPR may incur severe hypoxic brain injury.

    Postcardiac arrest brain injury significantly contributes to mortality and morbidity in patients suffering from cardiac arrest (CA). Evidence that shows that mitochondrial dysfunction appears to be a key factor in tissue damage after ischemia/reperfusion is accumulating. However, limited data are available regarding the cerebral mitochondrial dysfunction during CA and cardiopulmonary resuscitation (CPR) and its relationship to the alterations of high-energy phosphate. Here, we sought to identify alterations of mitochondrial morphology and oxidative phosphorylation function as well as high-energy phosphates during CA and CPR in a rat model of ventricular fibrillation (VF). We found that impairment of mitochondrial respiration and partial depletion of adenosine triphosphate (ATP) and phosphocreatine (PCr) developed in the cerebral cortex and hippocampus following a prolonged cardiac arrest. Optimal CPR might ameliorate the deranged phosphorus metabolism and preserve mitochondrial function. No obvious ultrastructural abnormalities of mitochondria have been found during CA. We conclude that CA causes cerebral mitochondrial dysfunction along with decay of high-energy phosphates, which would be mitigated with CPR. This study may broaden our understanding of the pathogenic processes underlying global cerebral ischemic injury and provide a potential therapeutic strategy that aimed at preserving cerebral mitochondrial function during CA.

    Objective. There are many smartphone-based applications (apps) for cardiopulmonary resuscitation (CPR) training. We investigated the conformity and the learnability/usability of these apps for CPR training and real-life supports. Methods. We conducted a mixed-method, sequential explanatory study to assess CPR training apps downloaded on two apps stores in South Korea. Apps were collected with inclusion criteria as follows, Korean-language instruction, training features, and emergency supports for real-life incidents, and analyzed with two tests; 15 medical experts evaluated the apps' contents according to current Basic Life Support guidelines in conformity test, and 15 nonmedical individuals examined the apps using System Usability Scale (SUS) in the learnability/usability test. Results. Out of 79 selected apps, five apps were included and analyzed. For conformity (ICC, 0.95, p < 0.001), means of all apps were greater than 12 of 20 points, indicating that they were well designed according to current guidelines. Three of the five apps yielded acceptable level (greater than 68 of 100 points) for learnability/usability. Conclusion. All the included apps followed current BLS guidelines and a majority offered acceptable learnability/usability for layperson. Current and developmental smartphone-based CPR training apps should include accurate CPR information and be easy to use for laypersons that are potential rescuers in real-life incidents. For Clinical Trials. This is a clinical trial, registered at the Clinical Research Information Service (CRIS, cris.nih.go.kr), number KCT0001840. PMID:27668257

    Cardiac arrest, though not common during coronary angiography, is increasingly occurring in the catheterization laboratory because of the expanding complexity of percutaneous interventions (PCI) and the patient population being treated. Manual chest compression in the cath lab is not easily performed, often interrupted, and can result in the provider experiencing excessive radiation exposure. Mechanical cardiopulmonary resuscitation (CPR) provides unique advantages over manual performance of chest compression for treating cardiac arrest in the cardiac cath lab. Such advantages include the potential for uninterrupted chest compressions, less radiation exposure, better quality chest compressions, and less crowded conditions around the catheterization table, allowing more attention to ongoing PCI efforts during CPR. Out-of-hospital cardiac arrest patients not responding to standard ACLS therapy can be transported to the hospital while mechanical CPR is being performed to provide safe and continuous chest compressions en route. Once at the hospital, advanced circulatory support can be instituted during ongoing mechanical CPR. This article summarizes the epidemiology, pathophysiology and nature of cardiac arrest in the cardiac cath lab and discusses the mechanics of CPR and defibrillation in that setting. It also reviews the various types of mechanical CPR and their potential roles in and on the way to the laboratory. (Circ J 2016; 80: 1292-1299).

    Knowledge and skills relating to cardiopulmonary resuscitation tend to be lost over time. The combination of simulation sessions with online video records and online feedback allows for an enduring record of skills sessions to assist students in retaining and revising their learning. This paper reports a qualitative evaluation of such a combination used in inter-disciplinary sessions for volunteer nursing and medical students. Methods included focus groups and free text questionnaires; data were gathered from fourteen students and three teachers. Students had used the online material in a variety of personal ways, and found that the addition to their learning was significant. Their memories of the simulation sessions and of the feedback received immediately afterwards were incomplete, and repeated viewing enabled them to identify good and poor practice with more confidence, and to reflect more carefully on their own and others' practice. Teachers found it easier to give more detailed feedback when given the chance to watch the video than immediately after the session. All felt that the sessions would ideally be embedded in the curriculum.

    ABSTRACT Objective: to compare the rate of return of spontaneous circulation (ROSC) and death after cardiac arrest, with and without the use of a metronome during cardiopulmonary resuscitation (CPR). Method: case-control study nested in a cohort study including 285 adults who experienced cardiac arrest and received CPR in an emergency service. Data were collected using In-hospital Utstein Style. The control group (n=60) was selected by matching patients considering their neurological condition before cardiac arrest, the immediate cause, initial arrest rhythm, whether epinephrine was used, and the duration of CPR. The case group (n=51) received conventional CPR guided by a metronome set at 110 beats/min. Chi-square and likelihood ratio were used to compare ROSC rates considering p≤0.05. Results: ROSC occurred in 57.7% of the cases, though 92.8% of these patients died in the following 24 hours. No statistically significant difference was found between groups in regard to ROSC (p=0.2017) or the occurrence of death (p=0.8112). Conclusion: the outcomes of patients after cardiac arrest with and without the use of a metronome during CPR were similar and no differences were found between groups in regard to survival rates and ROSC.

    Good quality cardiopulmonary resuscitation (CPR) is the mainstay of treatment for managing patients with out-of-hospital cardiac arrest (OHCA). Assessment of the quality of the CPR delivered is now possible through the electrocardiography (ECG) signal that can be collected by an automated external defibrillator (AED). This study evaluates a nonlinear approximation of the CPR given to the asystole patients. The raw ECG signal is filtered using ensemble empirical mode decomposition (EEMD), and the CPR-related intrinsic mode functions (IMF) are chosen to be evaluated. In addition, sample entropy (SE), complexity index (CI), and detrended fluctuation algorithm (DFA) are collated and statistical analysis is performed using ANOVA. The primary outcome measure assessed is the patient survival rate after two hours. CPR pattern of 951 asystole patients was analyzed for quality of CPR delivered. There was no significant difference observed in the CPR-related IMFs peak-to-peak interval analysis for patients who are younger or older than 60 years of age, similarly to the amplitude difference evaluation for SE and DFA. However, there is a difference noted for the CI (p < 0.05). The results show that patients group younger than 60 years have higher survival rate with high complexity of the CPR-IMFs amplitude differences. PMID:27529068

    We present an original method using a low cost accelerometer and a Kalman-filter based algorithm to monitor cardiopulmonary resuscitation chest compressions (CC) depth. A three-axis accelerometer connected to a computer was used during CC. A Kalman filter was used to retrieve speed and position from acceleration data. We first tested the algorithm for its accuracy and stability on surrogate data. The device was implemented for CC performed on a manikin. Different accelerometer locations were tested. We used a classical inertial navigation algorithm to reconstruct CPR depth and frequency. The device was found accurate enough to monitor CPR depth and its stability was checked for half an hour without any drift. Average error on displacement was ±0.5mm. We showed that depth measurement was dependent on the device location on the patient or the rescuer. The accuracy and stability of this small low-cost accelerometer coupled to a Kalman-filter based algorithm to reconstruct CC depth and frequency, was found well adapted and could be easily implemented.

    OBJECTIVE: The goal of the present study was to examine the decisions of pediatricians who teach neonatal resuscitation in Brazil, particularly those who start resuscitation in the delivery room for newborns born at 23-26 gestational weeks. METHODS: The present study was a cross-sectional study that used electronic questionnaires (Dec/11-Sep/13) sent to instructors of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics. The primary outcome was the gestational age at which the respondent said that he/she would initiate positive pressure ventilation in the delivery room. Latent class analysis was used to identify the major profiles of these instructors, and logistic regression was used to identify variables associated with belonging to one of the derived classes. RESULTS: Of 685 instructors, 82% agreed to participate. Two latent classes were identified: ‘pro-resuscitation' (instructors with a high probability of performing ventilation on infants born at 23-26 weeks) and ‘pro-limitation' (instructors with a high probability of starting ventilation only for infants born at 25-26 weeks). In the multivariate model, compared with the ‘pro-limitation' class, ‘pro-resuscitation' pediatricians were more likely to be board-certified neonatologists and less likely to base their decision on the probability of the infant's death or on moral/religious considerations. CONCLUSION: The pediatricians in the most aggressive group were more likely to be specialists in neonatology and to use less subjective criteria to make delivery room decisions. PMID:27166771

    Background Quality of cardiopulmonary resuscitation (CPR) is key to increase survival from cardiac arrest. Providing chest compressions with adequate rate and depth is difficult even for well-trained rescuers. The use of real-time feedback devices is intended to contribute to enhance chest compression quality. These devices are typically based on the double integration of the acceleration to obtain the chest displacement during compressions. The integration process is inherently unstable and leads to important errors unless boundary conditions are applied for each compression cycle. Commercial solutions use additional reference signals to establish these conditions, requiring additional sensors. Our aim was to study the accuracy of three methods based solely on the acceleration signal to provide feedback on the compression rate and depth. Materials and Methods We simulated a CPR scenario with several volunteers grouped in couples providing chest compressions on a resuscitation manikin. Different target rates (80, 100, 120, and 140 compressions per minute) and a target depth of at least 50 mm were indicated. The manikin was equipped with a displacement sensor. The accelerometer was placed between the rescuer’s hands and the manikin’s chest. We designed three alternatives to direct integration based on different principles (linear filtering, analysis of velocity, and spectral analysis of acceleration). We evaluated their accuracy by comparing the estimated depth and rate with the values obtained from the reference displacement sensor. Results The median (IQR) percent error was 5.9% (2.8–10.3), 6.3% (2.9–11.3), and 2.5% (1.2–4.4) for depth and 1.7% (0.0–2.3), 0.0% (0.0–2.0), and 0.9% (0.4–1.6) for rate, respectively. Depth accuracy depended on the target rate (p < 0.001) and on the rescuer couple (p < 0.001) within each method. Conclusions Accurate feedback on chest compression depth and rate during CPR is possible using exclusively the chest

    BACKGROUND It is unknown whether survival after in-hospital cardiopulmonary resuscitation (CPR) is improving and which patient and hospital characteristics predict survival. METHODS We examined fee-for-service Medicare data from 1992 to 2005 to identify beneficiaries ≥ 65 years old who received CPR in US hospitals. We examined temporal trends in the incidence of and survival after CPR, as well as patient and hospital-level predictors of survival to discharge. RESULTS We identified 433,985 cases of in-hospital CPR and 18.3% survived to discharge (95% CI 18.2-18.5%). Survival was static during this period. The incidence of CPR was 2.73 events per 1000 admissions and was higher among non-white patients. The proportion of dying patients receiving in-hospital CPR prior to death increased over time and was higher for non-white patients. Patients who were male, older, had more co-morbid illness, or were admitted from a skilled nursing facility had lower survival. Adjusted odds of survival for black patients were 23.6% lower than similar white patients (95% CI 21.2%-25.9%). The association between race and survival was partially explained by hospital effects: black patients were more likely to receive CPR in hospitals with lower post-CPR survival. Among patients surviving in-hospital CPR, the proportion of patients discharged home decreased over time. CONCLUSIONS Survival following in-hospital CPR did not improve from 1992-2005 and the proportion of patients receiving in-hospital CPR prior to death increased while the proportion of survivors discharged home after CPR decreased. Black race was associated with higher rates of CPR, but lower survival after CPR. PMID:19571280

    BACKGROUND: Few studies have examined the association of layperson characteristics with cardiopulmonary resuscitation (CPR) provision. Previous studies suggested provider characteristics, including age and gender, were associated with CPR quality, particularly chest compression (CC) depth. We sought to determine the association of subject characteristics, including age and gender with layperson CPR quality during an unannounced simulated CPR event. We hypothesized shallower CC depth in females, and older-aged subjects. METHODS: As part of a larger multicenter randomized controlled trial of CPR training for cardiac patients’ caregivers, CPR skills were assessed 6 months after training. We analyzed associations between subject characteristics and CC rate, CC depth and no-flow time. Each variable was analyzed independently; significant predictors determined via univariate analysis were assessed in a multivariate regression model. RESULTS: A total of 521 laypersons completed a 6-month CPR skills assessment and were included in the analysis. Mean age was 51.8±13.7 years, 75% were female, 57% were Caucasian. Overall, mean CC rate was 88.5±25.0 per minute, CC depth was 50.9±2.0 mm, and mean no-flow time was 15.9±2.7 sec/min. CC depth decreased significantly in subjects >62 years (P<0.001). Male subjects performed deeper CCs than female subjects (47.5±1.7 vs. 41.9±0.6, P<0.001). CONCLUSION: We found that layperson age >62 years and female gender are associated with shallower CC depth.

    Context: Cardiopulmonary resuscitation (CPR) and emergency cardiovascular care guidelines are periodically renewed and published by the American Heart Association. Formal training programs are conducted based on these guidelines. Despite widespread training CPR is often poorly performed. Hospital educators spend a significant amount of time and money in training health professionals and maintaining basic life support (BLS) and advanced cardiac life support (ACLS) skills among them. However, very little data are available in the literature highlighting the long-term impact of these training. Aims: To evaluate the impact of formal certified CPR training program on the knowledge and skill of CPR among nurses, to identify self-reported outcomes of attempted CPR and training needs of nurses. Setting and Design: Tertiary care hospital, Prospective, repeated-measures design. Subjects and Methods: A series of certified BLS and ACLS training programs were conducted during 2010 and 2011. Written and practical performance tests were done. Final testing was undertaken 3–4 years after training. The sample included all available, willing CPR certified nurses and experience matched CPR noncertified nurses. Statistical Analysis Used: SPSS for Windows version 21.0. Results: The majority of the 206 nurses (93 CPR certified and 113 noncertified) were females. There was a statistically significant increase in mean knowledge level and overall performance before and after the formal certified CPR training program (P = 0.000). However, the mean knowledge scores were equivalent among the CPR certified and noncertified nurses, although the certified nurses scored a higher mean score (P = 0.140). Conclusions: Formal certified CPR training program increases CPR knowledge and skill. However, significant long-term effects could not be found. There is a need for regular and periodic recertification. PMID:27303137

    This paper describes a new method for calculating chest compression depth and a simple chest-compression gauge for validating the accuracy of the method. The chest-compression gauge has two plates incorporating two magnetic coils, a spring, and an accelerometer. The coils are located at both ends of the spring, and the accelerometer is set on the bottom plate. Waveforms obtained using the magnetic coils (hereafter, "magnetic waveforms"), which are proportional to compression-force waveforms and the acceleration waveforms were measured at the same time. The weight factor expressing the relationship between the second derivatives of the magnetic waveforms and the measured acceleration waveforms was calculated. An estimated-compression-displacement (depth) waveform was obtained by multiplying the weight factor and the magnetic waveforms. Displacements of two large springs (with similar spring constants) within a thorax and displacements of a cardiopulmonary resuscitation training manikin were measured using the gauge to validate the accuracy of the calculated waveform. A laser-displacement detection system was used to compare the real displacement waveform and the estimated waveform. Intraclass correlation coefficients (ICCs) between the real displacement using the laser system and the estimated displacement waveforms were calculated. The estimated displacement error of the compression depth was within 2 mm (<1 standard deviation). All ICCs (two springs and a manikin) were above 0.85 (0.99 in the case of one of the springs). The developed simple chest-compression gauge, based on a new calculation method, provides an accurate compression depth (estimation error < 2 mm).

    Background The decision whether or not to undertake cardiopulmonary resuscitation (CPR) is a major ethical challenge. Patient preferences may be influenced by multiple factors, including information given by the media. Objectives We wanted to assess whether patients’ knowledge about CPR survival and outcomes was related to presentation by the media. Methods 100 consecutive patients with COPD and chronic respiratory failure (CRF) and 100 patients at their first hospital admission for respiratory problems were enrolled. A questionnaire was administered to the patients seeking to ascertain their exposure to health information from the media, and to obtain their opinions on 1) the probability of survival after CPR, 2) the maximal length of time from collapse to CPR that allows a reasonable chance of survival, and 3) long-term outcomes of CPR survivors. Results The patients overestimated the success rate of CPR (63% of them estimated a hospital survival >40%), while the estimate of long-term outcome and timing of the procedure were more realistic. Bivariate correlations analysis showed significant correlation between the rate of correct responses and the viewing of educational television programs (p = 0.039), but not medical stories, reading of health-oriented newspapers, use of the internet, age, educational level, and the presence of CRF. Conclusions In conclusion, we have shown that both COPD and “newly admitted” patients’ estimate of survival after CPR is much higher than reported by the current literature. A correct knowledge of CPR procedures and outcomes is significantly correlated with the exposure to “educational” medical TV programs, but not medical stories, newspapers, or internet sources.

    Background: There are several evaluation models that can be used to evaluate the effect of in-service training; one of them is the Kirkpatrick model. The aim of the present study is to assess the in-service training of cardiopulmonary resuscitation (CPR) for nurses based on the Kirkpatrick's model. Materials and Methods: This study is a cross-sectional study based on the Kirkpatrick's model in which the efficacy of in-service training of CPR to nurses was assessed in the Shahadaye Lenjan Hospital in Isfahan province in 2014. 80 nurses and Nurse's aides participated in the study after providing informed consent. The in-service training course was evaluated in reaction, learning, behavior, and results level of the Kirkpatrick model. Data were collected through a researcher-made questionnaire. Results: The mean age of the participants was 35 ± 8.5 years. The effectiveness score obtained in the reaction level (first level in the Kirkpatrick model) was 4.2 ± 0.32. The effectiveness score in the second level of model or the learning level was 4.70 ± 0.09, which is statistically significant (P < 0.001). The effectiveness score at the third and fourth level were 4.1 ± 0.34 and 4.3 ± 0.12, respectively. Total effectiveness score was 4.35. Conclusions: The results of this study showed that CPR in-service training has a favorable effect on all four levels of the Kirkpatrick model for nurses and nurse's aides. PMID:27904633

    Introduction Sudden cardiac arrest (CA) is a leading cause of death worldwide. Breathing nitric oxide (NO) reduces ischemia-reperfusion (IR) injury in animal models and in patients. The objective of this study was to learn whether inhaled NO improves outcomes after CA and cardiopulmonary resuscitation (CPR). Methods and Results Adult male mice were subjected to potassium-induced CA for 7.5 min whereupon CPR was performed with chest compression and mechanical ventilation. One hour after CPR, mice were extubated and breathed air alone or air supplemented with 40 parts per million (ppm) NO for 23h. Mice that were subjected to CA/CPR and breathed air exhibited a poor 10-day survival rate (4/13), depressed neurological and left ventricular (LV) function, and increased caspase-3 activation and inflammatory cytokine induction in the brain. Magnetic resonance imaging revealed brain regions with marked water diffusion abnormality 24h after CA/CPR in mice that breathed air. Breathing air supplemented with NO for 23h starting 1h after CPR attenuated neurological and LV dysfunction 4 days after CA/CPR and markedly improved 10-day survival rate (11/13, P=0.003 vs Air). The protective effects of inhaled NO on the outcome after CA/CPR were associated with reduced water diffusion abnormality, caspase-3 activation, and cytokine induction in the brain and increased serum NOx levels. Deficiency of the α1 subunit of soluble guanylate cyclase (sGC), a primary target of NO, abrogated the ability of inhaled NO to improve outcomes after CA/CPR. Conclusions These results suggest that NO inhalation after CA and successful CPR improves outcome via sGC-dependent mechanisms. PMID:21931083

    It is a bibliographic study about the identification of the motor capacities involved in the psychomotor skills of the cardiopulmonary resuscitation (CPR) which aims to obtain subsidies to the planning of the teaching-learning process of this skill. It was found that: the motor capacities involved in the psychomotor skill of the CPR technique are predominantly cognitive and motor, involving 9 perceptive-motor capacities and 8 physical proficiency capacities. The CPR technique is a psychomotor skill classified as open, done in series and categorized as a thin and global skill and the teaching-learning process of the CPR technique has an elevated degree of complexity.

    Background Out-of-hospital cardiac arrest (CA) is a prevalent medical crisis resulting in severe injury to the heart and brain and an overall survival of less than 10 percent. Mitochondrial dysfunction is predicted to be a key determinant of poor outcomes following prolonged CA. However, the onset and severity of mitochondrial dysfunction during CA and cardiopulmonary resuscitation (CPR) is not fully understood. Ischemic postconditioning (IPC), controlled pauses during the initiation of CPR, has been shown to improve cardiac function and neurologically favorable outcomes after fifteen minutes of CA. We tested the hypothesis that mitochondrial dysfunction develops during prolonged CA and can be rescued with IPC during CPR (IPC-CPR).

    In a recent German multicenter study, 25% of the patients who suffered a witnessed cardiac arrest outside the hospital were resuscitated successfully and were discharged from the hospital. Approximately 100,000 people suffer a fatal cardiac arrest in Germany annually, which is about ten times more than deaths resulting from motor vehicle accidents. New devices and techniques for cardiopulmonary resuscitation (CPR) have been developed in order to enhance the efficacy of chest compressions during CPR. The purpose of the present article is to review mechanisms of blood flow during CPR, to discuss CPR devices and techniques (vest CPR, CPR with interposed abdominal compressions, active compression-decompression (ACD) CPR, phased chest and abdominal compression-decompression CPR, and to further evaluate results from subsequently published laboratory and clinical studies. Vest CPR performs chest compressions with a pneumatic pump, which is able to compress the entire thorax with great force while minimizing injury. This device was developed to achieve an optimal driving force of the thoracic-pump mechanism during CPR. After promising results in laboratory studies and further technical development, vest CPR increased coronary perfusion pressure (CPP) in a clinical study even after 45 min of unsuccessful advanced cardiac life support. Currently, this device is being evaluated in an international multicenter study in Europe and the United States. A vest for employment by the emergency medical service (EMS) is in preparation. Interposed abdominal compressions during relaxation of the chest may augment artificial blood flow. In some laboratory studies, this mechanism resulted, in part, in promising data, and in another did not achieve better survival rates in comparison with standard CPR. No benefit of abdominal compressions was shown in an investigation in an EMS, whereas in a clinical study patients who were treated with interposed abdominal compressions were more likely to

    Post-mortem cross-sectional imaging in the form of CT and, less frequently, MRI is an emerging facility in the evaluation of cause-of-death and human identification for the coronial service as well as in assisting the forensic investigation of suspicious deaths and homicide. There are marked differences between the radiological evaluation and interpretation of the CT and MRI features of the live patient (i.e. antemortem imaging) and the evaluation and interpretation of post-mortem CT and MRI appearances. In addition to the absence of frequently utilized tissue enhancement following intravenous contrast administration in antemortem imaging, there are a number of variable changes which occur in the tissues and organs of the body as a normal process following death, some of which are, in addition, affected significantly by environmental factors. Many patients and victims will also have undergone aggressive attempts at cardiopulmonary resuscitation in the perimortem period which will also significantly alter post-mortem CT and MRI appearances. It is paramount that the radiologist and pathologist engaged in the interpretation of such post-mortem imaging are familiar with the appropriate non-pathological imaging changes germane to death, the post-mortem interval and cardiopulmonary resuscitation in order to avoid erroneously attributing such changes to trauma or pathology. Some of the more frequently encountered radiological imaging considerations of this nature will be reviewed. PMID:26562099

    2014-01-01

    Background Hypothermia has been used in cardiac surgery for many years for neuroprotection. Mild hypothermia (MH) [body temperature (BT) kept at 32–35°C] has been shown to reduce both mortality and poor neurological outcome in patients after cardiopulmonary resuscitation (CPR). This study investigated whether patients who were expected to benefit neurologically from therapeutic hypothermia (TH) also had improved cardiac function. Methods The study included 30 patients who developed in-hospital cardiac arrest between September 17, 2012, and September 20, 2013, and had return of spontaneous circulation (ROSC) following successful CPR. Patient BTs were cooled to 33°C using intravascular heat change. Basal BT, systolic artery pressure (SAP), diastolic artery pressure (DAP), mean arterial pressure (MAP), heart rate, central venous pressure, cardiac output (CO), cardiac index (CI), global end-diastolic volume index (GEDI), extravascular lung water index (ELWI), and systemic vascular resistance index (SVRI) were measured at 36°C, 35°C, 34°C and 33°C during cooling. BT was held at 33°C for 24 hours prior to rewarming. Rewarming was conducted 0.25°C/h. During rewarming, measurements were repeated at 33°C, 34°C, 35°C and 36°C. A final measurement was performed once patients spontaneously returned to basal BT. We compared cooling and rewarming cardiac measurements at the same BTs. Results SAP values during rewarming (34°C, 35°C and 36°C) were lower than during cooling (P < 0.05). DAP values during rewarming (basal temperature, 34°C, 35°C and 36°C) were lower than during cooling. MAP values during rewarming (34°C, 35°C and 36°C) were lower than during cooling (P < 0.05). CO and CI values were higher during rewarming than during cooling. GEDI and ELWI did not differ during cooling and rewarming. SVRI values during rewarming (34°C, 35°C, 36°C and basal temperature) were lower than during cooling (P < 0.05). Conclusions To our knowledge

    Aim: To evaluate, using a simulated haemodynamic circulation model, whether passive leg raising (PLR) is able to improve the effect during cardiopulmonary resuscitation (CPR); to expose the possible reasons why PLR works or not. Materials and Methods: We adapted a circulatory model for CPR with PLR. First we compared cardiac output (CO), coronary perfusion pressure (CPP), blood flow to heart (Qheart), and blood flow to neck and brain (Qhead) of standard chest compression-only CPR with and without PLR; second we simulated the effects of PLR in different situations, by varying the thoracic pump factor (TPF) from 0 to 1; third we simulated the effects when the legs are lifted to the different heights. Finally, we compared our results with those obtained from a published clinical study. Results: According to the simulation model, (1) When TPF is in the interval (0,1), CPP, CO, Qheart, and Qhead are improved with PLR, among them with half-thoracic/half-cardiac pump effect (TPF is 0.5), CPP, CO, Qhead, and Qheart increase the most (by 14, 14, 15, and 17%). (2) When TPF is 1 (pure thoracic pump, with an emphysema or extremely thick thorax), PLR has almost no effect on CPP, CO, and Qheart (−1, 2, and 0%), whereas Qhead is increased by 9%; (3) Regardless of whether there is a cardiac or thoracic pump effect, PLR is able to increase Qhead by 9–15%. (4) When the legs are lifted to 30° to the ground, the volume transferred from legs to upper body is 36% of the initial volume in legs; when the legs are lifted to 45°, the volume transferred is 43%; when the legs are lifted to 60°, the volume transferred is 47%; when the legs are lifted to 90°, the volume transferred is 50%. Conclusion: Generally PLR is able to achieve improved cerebral perfusion and coronary perfusion. In some extreme situations, it has no effect on cardiac output and coronary perfusion, but still improves cerebral perfusion. PLR could be a beneficial supplement to CPR, and it is not necessary to lift

    Performance of efficient single-person cardiopulmonary resuscitation (CPR) is vital to maintain cardiac and cerebral perfusion during the 2-4 min it takes for deployment of advanced life support during a space mission. The aim of the present study was to investigate potential differences in upper body muscle activity during CPR performance at terrestrial gravity (+1Gz) and in simulated microgravity (μG). Muscle activity of the triceps brachii, erector spinae, rectus abdominis and pectoralis major was measured via superficial electromyography in 20 healthy male volunteers. Four sets of 30 external chest compressions (ECCs) were performed on a mannequin. Microgravity was simulated using a body suspension device and harness; the Evetts-Russomano (ER) method was adopted for CPR performance in simulated microgravity. Heart rate and perceived exertion via Borg scores were also measured. While a significantly lower depth of ECCs was observed in simulated microgravity, compared with +1Gz, it was still within the target range of 40-50 mm. There was a 7.7% decrease of the mean (±SEM) ECC depth from 48 ± 0.3 mm at +1Gz, to 44.3 ± 0.5 mm during microgravity simulation (p < 0.001). No significant difference in number or rate of compressions was found between the two conditions. Heart rate displayed a significantly larger increase during CPR in simulated microgravity than at +1Gz, the former presenting a mean (±SEM) of 23.6 ± 2.91 bpm and the latter, 76.6 ± 3.8 bpm (p < 0.001). Borg scores were 70% higher post-microgravity compressions (17 ± 1) than post +1Gz compressions (10 ± 1) (p < 0.001). Intermuscular comparisons showed the triceps brachii to have significantly lower muscle activity than each of the other three tested muscles, in both +1Gz and microgravity. As shown by greater Borg scores and heart rate increases, CPR performance in simulated microgravity is more fatiguing than at +1Gz. Nevertheless, no significant difference in muscle activity between conditions

    Accumulating evidence illustrates the beneficial effects of dietary docosahexaenoic acid (DHA) on cardiovascular diseases. However, its effects on cardiac arrest (CA) remain controversial in epidemiological studies and have not been reported in controlled animal studies. Here, we examined whether dietary DHA can improve survival, the most important endpoint in CA. Male Sprague-Dawley rats were randomized into two groups and received either a control diet or a DHA-supplemented diet for 7–8 weeks. Rats were then subjected to 20 min asphyxia-induced cardiac arrest followed by 30 min cardiopulmonary bypass resuscitation. Rat survival was monitored for additional 3.5 h following resuscitation. In the control group, 1 of 9 rats survived for 4 h, whereas 6 of 9 rats survived in the DHA-treated group. Surviving rats in the DHA-treated group displayed moderately improved hemodynamics compared to rats in the control group 1 h after the start of resuscitation. Rats in the control group showed no sign of brain function whereas rats in the DHA-treated group had recurrent seizures and spontaneous respiration, suggesting dietary DHA also protects the brain. Overall, our study shows that dietary DHA significantly improves rat survival following 20 min of severe CA. PMID:27811958

  9. 'Resuscitation' of extremely preterm and/or low-birth-weight infants - time to 'call it'?

    Since ancient times, various methods have been used to revive apparently stillborn infants; many were of dubious efficacy and had the potential to cause harm. Based largely on studies of acutely asphyxiated term animal models, clinical assessment and positive pressure ventilation have become the cornerstones of neonatal resuscitation over the last 40 years. Over the last 25 years, care of extremely preterm infants in the delivery room has evolved from a policy of indifference to one of increasingly aggressive support. The survival of these infants has improved considerably in recent years; this has not, however, necessarily been due to more aggressive resuscitation. Urban myths have evolved that all extremely preterm infants died before they were intubated, and that all such infants need to immediately intubated or they will quickly die. This has never been true. Clinical assessment of infants at birth is subjective. Also, many techniques used to support preterm infants at birth have not been well studied and there is evidence that they may be harmful. It may thus be argued that many of our well-intentioned resuscitation interventions are of dubious efficacy and have the potential to cause harm. 'Resuscitation' is an emotive term which means 'restoration of life'. Death, thankfully, is a rare presentation in the delivery room. Therefore, concerning neonatal 'resuscitation', it is time to 'call it' something else. This will allow us to dispassionately distinguish preterm infants who are dead, or nearly dead, from those who are merely at high risk of parenchymal lung disease. We may then be able to refine our interventions and determine what methods of support benefit these infants most.

    End-of-life (EOL) decision making is based on the values and wishes of terminally ill patients. However, little is known on the extent to which cultural factors affect personal attitudes toward life-sustaining treatments (LSTs) such as cardiopulmonary resuscitation (CPR) in China. This study evaluated the cultural and ethical considerations during EOL decisions and assessed the factors that affect pursuing LSTs in China. We used a case-control study design and compared their baseline characteristics with the provided EOL care and treatments. The CPR treatment among patients with cancer at EOL was affected by Chinese family traditions and Western influences. Our results reflect the need to improve EOL care and treatment in China.

    The management of patients with acute stroke regarding treatment of thromboembolism is supported by a limited evidence base. We present the case of a 55-year-old female patient who initially presented with an ischaemic cerebral infarct with haemorrhagic transformation. Her clinical recovery was complicated by cardiac arrest secondary to massive pulmonary embolism. This was successfully treated with cardiopulmonary resuscitation and thrombolysis using Alteplase, which led to a full recovery to the pre-arrest state with no evidence of haemorrhagic complication. The patient was successfully discharged to a specialist centre for on-going stroke rehabilitation with no additional neurological impact. Despite the limited evidence base we believe this case highlights that thrombolysis can be used in select patients with haemorrhagic transformation of stroke and serious thromboembolic complications to achieve a positive outcome.

    BACKGROUND: This meta-analysis aimed to determine whether extracorporeal cardiopulmonary resuscitation (ECPR), compared with conventional cardiopulmonary resuscitation (CCPR), improves outcomes in adult patients with cardiac arrest (CA). DATA RESOURCES: PubMed, EMBASE, Web of Science, and China Biological Medicine Database were searched for relevant articles. The baseline information and outcome data (survival, good neurological outcome at discharge, at 3–6 months, and at 1 year after CA) were collected and extracted by two authors. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using Review Manager 5.3. RESULTS: In six studies 2 260 patients were enrolled to study the survival rate to discharge and long-term neurological outcome published since 2000. A significant effect of ECPR was observed on survival rate to discharge compared to CCPR in CA patients (RR 2.37, 95%CI 1.63–3.45, P<0.001), and patients who underwent ECPR had a better long-term neurological outcome than those who received CCPR (RR 2.79, 95%CI 1.96–3.97, P<0.001). In subgroup analysis, there was a significant difference in survival to discharge favoring ECPR over CCPR group in OHCA patients (RR 2.69, 95%CI 1.48–4.91, P=0.001). However, no significant difference was found in IHCA patients (RR 1.84, 95%CI 0.91–3.73, P=0.09). CONCLUSION: ECPR showed a beneficial effect on survival rate to discharge and long-term neurological outcome over CCPR in adult patients with CA. PMID:28123613

    Abstract Background. Survival outcomes from out-of-hospital cardiac arrest (OHCA) in Asia are poor (2-11%). Bystander cardiopulmonary resuscitation (CPR) rates are relatively low in Asia. Dispatcher-assisted CPR (DA-CPR) has recently emerged as a potentially cost-effective intervention to increase bystander CPR and survival from OHCA. The Pan-Asian Resuscitation Outcomes Study (PAROS), an Asia-Pacific cardiac arrest registry, was set up in 2009, with the aim of understanding OHCA as a disease in Asia and improving OHCA survival. The network has adopted DA-CPR as part of its strategy to improve OHCA survival. Objective. This article aims to describe the conceptualization, study design, potential benefits, and difficulties for implementation of DA-CPR trial in the Asia-Pacific. Methods. Two levels of intervention, basic and comprehensive, will be offered to PAROS participating sites. The basic level consists of implementation of a DA-CPR protocol and training program, while the comprehensive level consists of implementation of the basic level, with the addition of a dispatch quality measurement tool, quality improvement program, and community education program. Sites that are not able to implement the package will contribute control data. The primary outcome of the study is survival to hospital discharge or survival to 30 days post cardiac arrest. DA-CPR and bystander CPR are secondary outcomes. Conclusion. Implementation of DA-CPR requires concerted efforts by EMS leaders and supervisors, dispatchers, hospital stakeholders, policy makers, and the general public. The DA-CPR trial implemented by the PAROS sites, if successful, can serve as a model for other countries considering such an intervention in their EMS systems.

    Survival of very-low-birth-weight infants (VLBWI) depends on professional perinatal management that begins at delivery. Korean Neonatal Network data on neonatal resuscitation management and initial care of VLBWI of less than 33 weeks gestation born from January 2013 to June 2014 were reviewed to investigate the current practice of neonatal resuscitation in Korea. Antenatal data, perinatal data, and short-term morbidities were analyzed. Out of 2,132 neonates, 91.7% needed resuscitation at birth, chest compression was performed on only 104 infants (5.4%) and epinephrine was administered to 80 infants (4.1%). Infants who received cardiac compression and/or epinephrine administration at birth (DR-CPR) were significantly more acidotic (P < 0.001) and hypothermic (P < 0.001) than those who only needed positive pressure ventilation (PPV). On logistic regression, DR-CPR resulted in greater early mortality of less than 7 days (OR, 5.64; 95% CI 3.25-9.77) increased intraventricular hemorrhage ≥ grade 3 (OR, 2.71; 95% CI 1.57-4.68), periventricular leukomalacia (OR, 2.94; 95% CI 1.72-5.01), and necrotizing enterocolitis (OR, 2.12; 95% CI 1.15-3.91) compared with those infants who needed only PPV. Meticulous and aggressive management of infants who needed DR-CPR at birth and quality improvement of the delivery room management will result in reduced morbidities and early death for the vulnerable VLBWI.

    In cases of out-of hospital cardiac arrest (OHCA), falling to the ground can cause brain and neck trauma to the patient. We present a case of a man in his mid-60s who suffered from an OHCA resulting in a violent collapse. The patient received immediate cardiopulmonary resuscitation, but his spine was immobilised only after a large frontal haematoma was found. The resuscitation efforts resulted in return of spontaneous circulation and discharge from hospital. After this, doctors performed angioplasty, followed by a cardiopulmonary bypass. Later, CT scan examination reported a displaced and unstable fracture of the 6th vertebra without bone marrow involvement. The patient underwent a second operation. 40 days later, he was able to return home without sequela. This case shows the importance of analysing the circumstances of a fall, considering the possibility of two concomitant diagnoses and prioritising investigations and treatment.

    Objective We aimed to evaluate the attitudes of doctors about cardiopulmonary resuscitation (CPR) in this research. Methods Overall, 234 doctors who were working in Abant İzzet Baysal University Health Research and Application Center and who accepted to participate in this research were included. Research data were obtained by a questionnaire containing questions about demographic characteristics of doctors and their knowledge about CPR. Questionnaires were applied between 27.02.2012 and 04.06.2012. The chi-square test was used for categorical variables. A value of p<0.05 was considered statistically significant. Results It was determined that 90% of the participants included in the study applied and/or observed CPR, and 62% of participants did not attend any CPR course. In addition, 64.1% of the doctors were found to be aware of guidelines prepared every 5 years. Although 65.2% of the doctors who attended a course previously gave a correct answer for the question about the number of cardiac compressions during adult CPR, 47.6% of the doctors who did not attend a course gave the correct answer (p=0.014). Additionally, 71.9% of participants who attended a course previously and 51.7% of participants who did not replied correctly to the question ‘What should be done immediately after defibrillation during CPR?’ And also the results for the question about how many joules is necessary to begin defibrillation with a monophasic defibrillator were statistically significant according to the attendance for a CPR course (p<0.005). Conclusion In this study, we have identified the lack of knowledge of the doctors about resuscitation. PMID:27366577

    Purpose Decision making regarding cardiopulmonary resuscitation (CPR) is challenging. This study examined the effect of a video decision support tool on CPR preferences among patients with advanced cancer. Patients and Methods We performed a randomized controlled trial of 150 patients with advanced cancer from four oncology centers. Participants in the control arm (n = 80) listened to a verbal narrative describing CPR and the likelihood of successful resuscitation. Participants in the intervention arm (n = 70) listened to the identical narrative and viewed a 3-minute video depicting a patient on a ventilator and CPR being performed on a simulated patient. The primary outcome was participants' preference for or against CPR measured immediately after exposure to either modality. Secondary outcomes were participants' knowledge of CPR (score range of 0 to 4, with higher score indicating more knowledge) and comfort with video. Results The mean age of participants was 62 years (standard deviation, 11 years); 49% were women, 44% were African American or Latino, and 47% had lung or colon cancer. After the verbal narrative, in the control arm, 38 participants (48%) wanted CPR, 41 (51%) wanted no CPR, and one (1%) was uncertain. In contrast, in the intervention arm, 14 participants (20%) wanted CPR, 55 (79%) wanted no CPR, and 1 (1%) was uncertain (unadjusted odds ratio, 3.5; 95% CI, 1.7 to 7.2; P < .001). Mean knowledge scores were higher in the intervention arm than in the control arm (3.3 ± 1.0 v 2.6 ± 1.3, respectively; P < .001), and 65 participants (93%) in the intervention arm were comfortable watching the video. Conclusion Participants with advanced cancer who viewed a video of CPR were less likely to opt for CPR than those who listened to a verbal narrative. PMID:23233708

    Objective We compared training using a voice advisory manikin (VAM) with an instructor-led (IL) course in terms of acquisition of initial cardiopulmonary resuscitation (CPR) skills, as defined by the 2010 resuscitation guidelines. Methods This study was a randomized, controlled, blinded, parallel-group trial. We recruited 82 first-year emergency medical technician students and distributed them randomly into two groups: the IL group (n=41) and the VAM group (n=37). In the IL-group, participants were trained in “single-rescuer, adult CPR” according to the American Heart Association’s Basic Life Support course for healthcare providers. In the VAM group, all subjects received a 20-minute lesson about CPR. After the lesson, each student trained individually with the VAM for 1 hour, receiving real-time feedback. After the training, all subjects were evaluated as they performed basic CPR (30 compressions, 2 ventilations) for 4 minutes. Results The proportion of participants with a mean compression depth ≥50 mm was 34.1% in the IL group and 27.0% in the VAM group, and the proportion with a mean compression depth ≥40 mm had increased significantly in both groups compared with ≥50 mm (IL group, 82.9%; VAM group, 86.5%). However, no significant differences were detected between the groups in this regard. The proportion of ventilations of the appropriate volume was relatively low in both groups (IL group, 26.4%; VAM group, 12.5%; P=0.396). Conclusion Both methods, the IL training using a practice-while-watching video and the VAM training, facilitated initial CPR skill acquisition, especially in terms of correct chest compression.

    Background Sudden cardiac arrest (CA) is one of the leading causes of death worldwide. We sought to evaluate the impact of hydrogen sulfide (H2S) on the outcome after CA and cardiopulmonary resuscitation (CPR) in mouse. Methods and Results Mice were subjected to 8 min of normothermic CA and resuscitated with chest compression and mechanical ventilation. Seven minutes after the onset of CA, mice received sodium sulfide (Na2S, 0.55 mg/kg i.v.) or vehicle 1 min before CPR. There was no difference in the rate of return of spontaneous circulation (ROSC), CPR time to ROSC, and left ventricular (LV) function at ROSC between groups. Administration of Na2S 1 min before CPR markedly improved survival rate at 24h after CPR (15/15) compared to vehicle (10/26, P=0.0001 vs Na2S). Administration of Na2S prevented CA/CPR-induced oxidative stress and ameliorated LV and neurological dysfunction 24h after CPR. Delayed administration of Na2S at 10 min after CPR did not improve outcomes after CA/CPR. Cardioprotective effects of Na2S were confirmed in isolated-perfused mouse hearts subjected to global ischemia and reperfusion. Cardiomyocyte-specific overexpression of cystathionine γ-lyase (CGL, an enzyme that produces H2S) markedly improved outcomes of CA/CPR. Na2S increased phosphorylation of NOS3 in LV and brain cortex, increased serum nitrite/nitrate levels, and attenuated CA-induced mitochondrial injury and cell death. NOS3 deficiency abrogated the protective effects of Na2S on the outcome of CA/CPR. Conclusions These results suggest that administration of Na2S at the time of CPR improves outcome after cardiac arrest possibly via an NOS3-dependent signaling pathway. PMID:19704099

    Background Therapeutic hypothermia (TH) improves neurological outcomes after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). Although nitric oxide prevents organ injury induced by ischemia and reperfusion, role of nitric oxide during TH after CPR remains unclear. Here, we examined the impact of endogenous nitric oxide synthesis on the beneficial effects of hypothermia after CA/CPR. We also examined whether or not inhaled nitric oxide during hypothermia further improves outcomes after CA/CPR in mice treated with TH. Methods Wild-type (WT) mice and mice deficient for nitric oxide synthase 3 (NOS3−/−) were subjected to CA at 37°C and then resuscitated with chest compression. Body temperature was maintained at 37°C (normothermia) or reduced to 33°C (TH) for 24 hours after resuscitation. Mice breathed air or air mixed with nitric oxide at 10, 20, 40, 60, or 80 ppm during hypothermia. To evaluate brain injury and cerebral blood flow, magnetic resonance imaging was performed in WT mice after CA/CPR. Results Hypothermia up-regulated the NOS3-dependent signaling in the brain (n=6–7). Deficiency of NOS3 abolished the beneficial effects of hypothermia after CA/CPR (n=5–6). Breathing nitric oxide at 40 ppm improved survival rate in hypothermia-treated NOS3−/− mice (n=6) after CA/CPR compared to NOS3−/− mice that were treated with hypothermia alone (n=6, P<0.05). Breathing nitric oxide at 40 (n=9) or 60 (n=9) ppm markedly improved survival rates in TH-treated WT mice (n=51) (both P<0.05 vs TH-treated WT mice). Inhaled nitric oxide during TH (n=7) prevented brain injury compared to TH alone (n=7) without affecting cerebral blood flow after CA/CPR (n=6). Conclusions NOS3 is required for the beneficial effects of TH. Inhaled nitric oxide during TH remains beneficial and further improves outcomes after CA/CPR. Nitric oxide breathing exerts protective effects after CA/CPR even when TH is ineffective due to impaired endogenous nitric oxide production

    In this series of animal experiments on resuscitation after cardiac arrest we had a unique opportunity to measure hyperspectral near-infrared spectroscopy (hNIRS) parameters directly on the brain dura, or on the brain through the intact pig skull, and simultaneously the muscle hNIRS parameters. Simultaneously the arterial blood pressure and carotid and femoral blood flow were recorded in real time using invasive sensors. We used a novel hyperspectral signalprocessing algorithm to extract time-dependent concentrations of water, hemoglobin, and redox state of cytochrome c oxidase during cardiac arrest and resuscitation. In addition in order to assess the validity of the non-invasive brain measurements the obtained results from the open brain was compared to the results acquired through the skull. The comparison of hNIRS data acquired on brain surface and through the adult pig skull shows that in both cases the hemoglobin and the redox state cytochrome c oxidase changed in similar ways in similar situations and in agreement with blood pressure and flow changes. The comparison of simultaneously measured brain and muscle changes showed expected differences. Overall the results show feasibility of transcranial hNIRS measurements cerebral parameters including the redox state of cytochrome oxidase in human cardiac arrest patients.

    "Organ preserving cardiopulmonary resuscitation (OP-CPR)" is defined as the use of CPR in cases of cardiac arrest to preserve organs for transplantation, rather than to revive the patient. Is it ethical to provide OP-CPR in a brain-dead organ donor to save organs that would otherwise be lost? To answer this question, we review the literature on brain-dead organ donors, conduct an ethical analysis, and make recommendations. We conclude that OP-CPR can benefit patients and families by fulfilling the wish to donate. However, it is an aggressive procedure that can cause physical damage to patients, and risks psychological harm to families and healthcare professionals. In a brain-dead organ donor, OP-CPR is acceptable without specific informed consent to OP-CPR, although advance discussion with next of kin regarding this possibility is strongly advised. In a patient where brain death is yet to be determined, but there is known wish for organ donation, OP-CPR would only be acceptable with a specific informed consent from the next of kin. When futility of treatment has not been established or it is as yet unknown if the patient wished to be an organ donor then OP-CPR should be prohibited, in order to avoid any conflict of interest.

    Objective(s): The aim of this study was to investigate the effects of mild hypothermia therapy on oxidative stress injury of rabbit brain tissue after cardiopulmonary resuscitation (CPR). Materials and Methods: Rabbit models of cardiac arrest were established. After the restoration of spontaneous circulation, 50 rabbits were randomly divided into normothermia and hypothermia groups. The following five time points were selected: before CPR, immediately after CPR, 2 hr after CPR (hypothermia group reached the target temperature), 14 hr after CPR (hypothermia group before rewarming), and 24 hr after CPR (hypothermia group recovered to normal temperature). Glutathione (GSH) concentrations in both the blood and cerebrospinal fluid of the normothermia and hypothermia groups were measured. Results: At 2, 14, and 24 hr after CPR, the GSH concentrations in both the blood and cerebrospinal fluid were significantly higher in the hypothermia group than in the nomorthermia group. Conclusion: Mild hypothermia therapy may increase GSH concentrations in rabbit blood and cerebrospinal fluid after CPR as well as promote the recovery of cerebral function. PMID:25810895

  5. Effect of continuous compression and 30:2 cardiopulmonary resuscitation on cerebral microcirculation in a porcine model of cardiac arrest

    2013-01-01

    Background The effect of rescue breathing on neurologic prognosis after cardiopulmonary resuscitation (CPR) is controversial. Therefore, we investigated the cerebral microcirculatory and oxygen metabolism during continuous compression (CC) and 30:2 CPR (VC) in a porcine model of cardiac arrest to determine which is better for neurologic prognosis after CPR. Methods After 4 min of ventricular fibrillation, 20 pigs were randomised into two groups (n=10/group) receiving CC-CPR or VC-CPR. Cerebral oxygen metabolism and blood flow were measured continuously using laser Doppler flowmetry. Haemodynamic data were recorded at baseline and 5 min, 30 min, 2 h and 4 h after restoration of spontaneous circulation (ROSC). Results Compared with the VC group, the mean cortical cerebral blood flow was significantly higher at 5 min ROSC in the CC group (P<0.05), but the difference disappeared after that time point. Brain percutaneous oxygen partial pressures were higher, and brain percutaneous carbon dioxide partial pressures were lower, in the VC group from 30 min to 4 h after ROSC; significant differences were found between the two groups (P<0.05). However, no significant difference of the cerebral oxygen extraction fraction existed between the two groups. Conclusions Inconsistency of systemic circulation and cerebral microcirculation with regard to blood perfusion and oxygen metabolism is common after CPR. No significant differences in cortical blood flow and oxygen metabolism were found between the CC-CPR and VC-CPR groups after ROSC. PMID:23849600

    Electroencephalogram reactivity (EEG-R) is a positive predictive factor for assessing outcomes in comatose patients. Most studies assess the prognostic value of EEG-R utilizing visual analysis; however, this method is prone to subjectivity. We sought to categorize EEG-R with a quantitative approach. We retrospectively studied consecutive comatose patients who had an EEG-R recording performed 1-3 days after cardiopulmonary resuscitation (CPR) or during normothermia after therapeutic hypothermia. EEG-R was assessed via visual analysis and quantitative analysis separately. Clinical outcomes were followed-up at 3-month and dichotomized as recovery of awareness or no recovery of awareness. A total of 96 patients met the inclusion criteria, and 38 (40%) patients recovered awareness at 3-month followed-up. Of 27 patients with EEG-R measured with visual analysis, 22 patients recovered awareness; and of the 69 patients who did not demonstrated EEG-R, 16 patients recovered awareness. The sensitivity and specificity of visually measured EEG-R were 58% and 91%, respectively. The area under the receiver operating characteristic curve for the quantitative analysis was 0.92 (95% confidence interval, 0.87-0.97), with the best cut-off value of 0.10. EEG-R through quantitative analysis might be a good method in predicting the recovery of awareness in patients with post-anoxic coma after CPR.

    Utstein-style guidelines contribute to improved public health internationally by providing a structured framework with which to compare emergency medical services systems. Advances in resuscitation science, new insights into important predictors of outcome from out-of-hospital cardiac arrest, and lessons learned from methodological research prompted this review and update of the 2004 Utstein guidelines. Representatives of the International Liaison Committee on Resuscitation developed an updated Utstein reporting framework iteratively by meeting face to face, by teleconference, and by Web survey during 2012 through 2014. Herein are recommendations for reporting out-of-hospital cardiac arrest. Data elements were grouped by system factors, dispatch/recognition, patient variables, resuscitation/postresuscitation processes, and outcomes. Elements were classified as core or supplemental using a modified Delphi process primarily based on respondents' assessment of the evidence-based importance of capturing those elements, tempered by the challenges to collect them. New or modified elements reflected consensus on the need to account for emergency medical services system factors, increasing availability of automated external defibrillators, data collection processes, epidemiology trends, increasing use of dispatcher-assisted cardiopulmonary resuscitation, emerging field treatments, postresuscitation care, prognostication tools, and trends in organ recovery. A standard reporting template is recommended to promote standardized reporting. This template facilitates reporting of the bystander-witnessed, shockable rhythm as a measure of emergency medical services system efficacy and all emergency medical services system-treated arrests as a measure of system effectiveness. Several additional important subgroups are identified that enable an estimate of the specific contribution of rhythm and bystander actions that are key determinants of outcome.

    Dantrolene was introduced for treatment of malignant hyperthermia. It also has antiarrhythmic properties and may thus be an alternative to amiodarone for the treatment of ventricular fibrillation (VF). Aim of this study was to compare the return of spontaneous circulation (ROSC) with dantrolene and amiodarone in a pig model of cardiac arrest. VF was induced in anesthetized pigs. After 8 min of untreated VF, chest compressions and ventilation were started and one of the drugs (amiodarone 5 mg kg−1, dantrolene 2.5 mg kg−1 or saline) was applied. After 4 min of initial CPR, defibrillation was attempted. ROSC rates, hemodynamics and cerebral perfusion measurements were measured. Initial ROSC rates were 7 of 14 animals in the dantrolene group vs. 5 of 14 for amiodarone, and 3 of 10 for saline). ROSC persisted for the 120 min follow-up in 6 animals in the dantrolene group, 4 after amiodarone and 2 in the saline group (n.s.). Hemodynamics were comparable in both dantrolene group amiodarone group after obtaining ROSC. Dantrolene and amiodarone had similar outcomes in our model of prolonged cardiac arrest, However, hemodynamic stability was not significantly improved using dantrolene. Dantrolene might be an alternative drug for resuscitation and should be further investigated. PMID:28098197

    Rosuvastatin, a potent HMG-CoA reductase inhibitor, is cholesterol-lowering drugs and reduce the risk of myocardial infarction and stroke. This study is to explore whether rosuvastatin improves outcomes after cardiac arrest in rats. Male Sprague-Dawley rats were subjected to 8min of cardiac arrest (CA) by asphyxia and randomly assigned to three experimental groups immediately following successful resuscitation: Sham; Control; and Rosuvastatin. The survival, hemodynamics, myocardial function, neurological outcomes and apoptosis were assessed. The 7-d survival rate was greater in the rosuvastatin treated group compared to the Control group (P=0.019 by log-rank test). Myocardial function, as measured by cardiac output and ejection fraction, was significantly impaired after CA and notably improved in the animals treated with rosuvastatin beginning at 60min after return of spontaneous circulation (ROSC) (P<0.05). Moreover, rosuvastatin treatment significantly ameliorated brain injury after ROSC, which was characterized by the increase of neurological function scores, and reduction of brain edema in cortex and hippocampus (P<0.05). Meanwhile, the levels of cardiac troponin T and neuron-specific enolase and the caspase-3 activity were significantly decreased in the Rosuvastatin group when compared with the Control group (P<0.05). In conclusion, rosuvastatin treatment substantially improves the 7-d survival rate as well as myocardial function and neurological outcomes after ROSC.

    Background Emergency medical practices are often team efforts. Training for various tasks and collaborations may be carried out in virtual environments. Although promising results exist from studies of serious games, little is known about the subjective reactions of learners when using multiplayer virtual world (MVW) training in medicine. Objective The objective of this study was to reach a better understanding of the learners’ reactions and experiences when using an MVW for team training of cardiopulmonary resuscitation (CPR). Methods Twelve Swedish medical students participated in semistructured focus group discussions after CPR training in an MVW with partially preset options. The students’ perceptions and feelings related to use of this educational tool were investigated. Using qualitative methodology, discussions were analyzed by a phenomenological data-driven approach. Quality measures included negotiations, back-and-forth reading, triangulation, and validation with the informants. Results Four categories characterizing the students’ experiences could be defined: (1) Focused Mental Training, (2) Interface Diverting Focus From Training, (3) Benefits of Practicing in a Group, and (4) Easy Loss of Focus When Passive. We interpreted the results, compared them to findings of others, and propose advantages and risks of using virtual worlds for learning. Conclusions Beneficial aspects of learning CPR in a virtual world were confirmed. To achieve high participant engagement and create good conditions for training, well-established procedures should be practiced. Furthermore, students should be kept in an active mode and frequent feedback should be utilized. It cannot be completely ruled out that the use of virtual training may contribute to erroneous self-beliefs that can affect later clinical performance. PMID:27986645

    Most frequent complications of infusion therapy in children include thrombosis and thrombophlebitis of the umbilical and subclavian veins. In the perinatal period thrombophlebitis of the umbilical vein is due to exogenous infection and becomes the source of umbilical sepsis. Thrombophlebitis of the subclavian vein in nurslings results more frequently from endogenous infection. Because of morpho-functional immaturity in infancy, hyperhydration of tissues is extreme, with vacuolar dystrophy of cells up to their necrosis, particularly in the liver and kidneys. Artificial pulmonary ventilation (APV), particularly in premature newborns, is frequently accompanied by breaks of alveolar septae, development of bullous and interstitial emphysema, pneumothorax. In deeply premature infants APV may be ineffective because of immaturity of the lung tissue.

    This study was conducted to identify the educational effects of a blended e-learning program for graduating nursing students on self-efficacy, problem solving, and psychomotor skills for core basic nursing skills. A one-group pretest/posttest quasi-experimental design was used with 79 nursing students in Korea. The subjects took a conventional 2-week lecture-based practical course, together with spending an average of 60 minutes at least twice a week during 2 weeks on the self-guided e-learning content for basic cardiopulmonary resuscitation and defibrillation using Mosby's Nursing Skills database. Self- and examiner-reported data were collected between September and November 2014 and analyzed using descriptive statistics, paired t test, and Pearson correlation. The results showed that subjects who received blended e-learning education had improved problem-solving abilities (t = 2.654) and self-efficacy for nursing practice related to cardiopulmonary resuscitation and defibrillation (t = 3.426). There was also an 80% to 90% rate of excellent postintervention performance for the majority of psychomotor skills, but the location of chest compressions, compression rate per minute, artificial respiration, and verification of patient outcome still showed low levels of performance. In conclusion, blended E-learning, which allows self-directed repetitive learning, may be more effective in enhancing nursing competencies than conventional practice education.

    Comparative data of thoracic compression response between live vs. post mortem human subjects (PMHS) has been reported, but the live subject tests are often at low deflections and include the effects of muscle tensing. Novel technology has been developed that overcomes several of these limitations. Specifically, a load cell and accelerometer has been integrated into a clinical monitor-defibrillator to measure chest compression and applied force during live human cardio-pulmonary resuscitation (CPR). The sensor is interposed between the hands of the person administering CPR and the sternum of the patient. The objective of this study was to compare the thoracic force-deflection measured during adult CPR to that measured during hub-based loading of adult PMHS. CPR represents a unique setting in which to study the mechanics of the chest as the thorax is loaded to a maximum chest deflection similar to that seen in a frontal crash environment and the effects of muscle tensing are minimized. PMHS and CPR data were modeled with a progressive spring in parallel with a viscous damper. Statistical comparison of the model parameters used to describe the compliance of the thorax during large compressions revealed that under the specific loading conditions tested, chest compressions during CPR generated less force at equivalent deflections than the PMHS. Specifically, the spring force at 40 mm deflection was 286 N for the CPR data and 588 N for the PMHS. Differences in area of load application and thoracic structures engaged, however, may partially explain these differences. In addition, the chest response during CPR demonstrated more hysteresis than the PMHS suggesting that the viscoelastic nature of the thorax is more pronounced when tissues are naturally perfused and substantial tissue autolysis has not begun. This study presents fundamental biomechanical data on the mechanical response of the adult thorax that increases our understanding of any potential differences between

This document has been developed to provide guidance for the full range of healthcare professionals who may encounter people with CIEDs in the situations described and for healthcare managers and commissioners. The authors recognise that some patients and people close to patients may also wish to refer to this document. It is intended as an initial step to help to ensure that people who have CIEDs, or are considering implantation of one, receive explanation of and understand the practical implications and decisions that this entails; to promote a good standard of care and service provision for people in the UK with CIEDs in the circumstances described; to offer relevant ethical and legal guidance on this topic; to offer guidance on the delivery of services in relation to deactivation of CIEDs where appropriate; to offer guidance on whether any special measures are needed when a person with a CIED receives cardiopulmonary resuscitation; and to offer guidance on the actions needed when a person with a CIED dies.

    In this study, we aimed to compare the effects of low- and high-quality cardiopulmonary resuscitation (CPR) on cardioprotection by induced hypothermia (IH) at 34 °C and examine whether extracellular signal-regulated kinase or endothelial nitric oxide synthase mediates this cardioprotection. Left ventricle infarct sizes were evaluated in six groups of rat hearts (n = 6) following Langendorff perfusion and triphenyltetrazolium chloride staining. Controls underwent 30 min of global ischemia at 37 °C, followed by 10 min of simulated low- or high-quality CPR reperfusion and 90 min of reperfusion at 75 mmHg. The IH groups underwent IH at 34 °C during reperfusion. The U0126 group received U0126 (60 μM)-an extracellular signal-regulated kinase inhibitor-during reperfusion at 34 °C. The L-NIO (N-(1-iminoethyl)-L-ornithine dihydrochloride) group received L-NIO (2 μM)-an endothelial nitric oxide synthase inhibitor-5 min before global ischemia at 37 °C to the end of reperfusion at 34 °C. Infarct size did not significantly differ between the control and IH groups receiving low-quality CPR. However, IH with high-quality CPR reduced the infarct size from 47.2% ± 10.2% to 26.0% ± 9.4% (P = 0.005). U0126 reversed the IH-induced cardioprotection (45.9% ± 9.4%, P = 0.010), whereas L-NIO had no significant effect. Cardiopulmonary resuscitation quality affects IH-induced cardioprotection. Extracellular signal-regulated kinase may mediate IH-induced cardioprotection.

    Extracorporeal cardiopulmonary resuscitation (ECPR) in children with cardiac arrest refractory to conventional cardiopulmonary resuscitation (CPR) has been reported with encouraging results. We reviewed outcomes of neonates with functional single ventricle (FSV) surviving post-cardiotomy ECPR after hospital discharge. Fifty-eight patients who required post-cardiotomy extracorporeal membrane oxygenation (ECMO) since the introduction of our ECPR protocol (January 2007-December 2011) were identified. Forty-one were neonates. Survival analysis was conducted. Of 41 neonates receiving post-cardiotomy ECMO, 32 had FSV. Twenty-one had ECPR. Fourteen underwent Norwood operation (NO) for hypoplastic left heart syndrome (HLHS). Seven had non-HLHS FSV. Four (of 7) underwent modified NO/DKS with systemic-to-pulmonary shunt (SPS), 2 SPS only and 1 SPS with anomalous pulmonary venous connection repair. Mean age was 6.8 ± 2.1 days. ECMO median duration was 7 days [interquartile range (IQR25-75: 4-18)]. Survival to ECMO discontinuation was 72% (15 of 21 patients) and at hospital discharge 62% (13 of 21 patients). The most common cause of late attrition was cardiac. At last follow-up (median: 22 months; IQR25-75: 3-36), 47% of patients were alive. Duration of ECMO and failure of lactate clearance within 24 h from ECMO deployment determined late survival after hospital discharge (p < 0.05). Rescue post-cardiotomy ECMO support in neonates with FSV carries significant late attrition. ECMO duration and failure in lactate clearance after deployment are associated with unfavorable outcome. Emphasis on CPR quality, refinement of management directives early during ECMO and aggressive early identification of patients requiring heart transplantation might improve late survival.

    Across Canada, the rate of preterm birth (i.e., at < 37 weeks' gestation) has been steadily increasing. Advances in perinatal medicine and neonatal intensive care have resulted in an increased capacity to intervene at the extremes of prematurity, leading to an increase in the overall survival of infants born at early gestations. There has been little corresponding decrease in long-term complications. As a result, additional stresses are placed on neonatal intensive care units across the country, impacting families, health care professionals, and society as a whole. Moral distress and moral residue are often cited in the neonatal-perinatal literature as stressors experienced by those who participate in the resuscitation decision-making process. They are directly related to the challenge of making a concrete decision about life and death at extremely early gestations in the context of long-term uncertainty. In this review, we performed a systematic search of medical and ethics literature pertaining to resuscitation at the extremes of prematurity. The perspective of health care professionals is explored, including how definitions of viability and parental perspectives contribute to the decision-making process. We argue for the necessity of further research exploring the inter-professional context of ethical decision making at the extremes of prematurity.

    Near-infrared spectroscopy (NIRS) is a non-invasive tool to measure real-time tissue oxygenation in the brain. In an invasive animal experiment we were able to directly compare non-invasive NIRS measurements on the skull with invasive measurements directly on the brain dura matter. We used a broad-band, continuous-wave hyper-spectral approach to measure tissue oxygenation in the brain of pigs under the conditions of cardiac arrest, cardiopulmonary resuscitation (CPR), and defibrillation. An additional purpose of this research was to find a correlation between mortality due to cardiac arrest and inadequacy of the tissue perfusion during attempts at resuscitation. Using this technique we measured the changes in concentrations of oxy-hemoglobin [HbO2] and deoxy-hemoglobin [HHb] to quantify the tissue oxygenation in the brain. We also extracted cytochrome c oxidase changes Δ[Cyt-Ox] under the same conditions to determine increase or decrease in cerebral oxygen delivery. In this paper we proved that applying CPR, [HbO2] concentration and tissue oxygenation in the brain increase while [HHb] concentration decreases which was not possible using other measurement techniques. We also discovered a similar trend in changes of both [Cyt-Ox] concentration and tissue oxygen saturation (StO2). Both invasive and non-invasive measurements showed similar results.

    Prevention of aortocaval compression is essential for effective cardiopulmonary resuscitation in late pregnancy. This can be achieved by either lateral maternal tilt or lateral uterine displacement. Results from a previous manikin study show that a firm foam-rubber wedge allowed successful chest compressions whilst providing stable and reliable lateral tilt. However, it did not investigate resuscitation in the supine position with manual uterine displacement. The aim of this study was to compare the effectiveness of chest compressions in a manikin in the supine position vs lateral tilt using a foam-rubber wedge, both on the floor and on a typical patient bed. Overall, we found that compressions were easier to perform in the supine position (p = 0.007 (bed) and 0.048 (floor)), and with greater stability in the supine position on the floor (p = 0.011). The effectiveness of chest compressions was similar in both the supine/uterine displacement and the lateral tilt positions, suggesting that either method may be suitable for CPR.

    Mild hypothermia improves survival and neurological recovery after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). However, the mechanism underlying this phenomenon is not fully elucidated. The aim of this study was to determine whether mild hypothermia alleviates early blood–brain barrier (BBB) disruption. We investigated the effects of mild hypothermia on neurologic outcome, survival rate, brain water content, BBB permeability and changes in tight junctions (TJs) and adherens junctions (AJs) after CA and CPR. Pigs were subjected to 8 min of untreated ventricular fibrillation followed by CPR. Mild hypothermia (33°C) was intravascularly induced and maintained at this temperature for 12 h, followed by active rewarming. Mild hypothermia significantly reduced cortical water content, decreased BBB permeability and attenuated TJ ultrastructural and basement membrane breakdown in brain cortical microvessels. Mild hypothermia also attenuated the CPR-induced decreases in TJ (occludin, claudin-5, ZO-1) and AJ (VE-cadherin) protein and mRNA expression. Furthermore, mild hypothermia decreased the CA- and CPR-induced increases in matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) expression and increased angiogenin-1 (Ang-1) expression. Our findings suggest that mild hypothermia attenuates the CA- and resuscitation-induced early brain oedema and BBB disruption, and this improvement might be at least partially associated with attenuation of the breakdown of TJ and AJ, suppression of MMP-9 and VEGF expression, and upregulation of Ang-1 expression.

    Nonanaphylactic noncardiogenic pulmonary edema leading to cardiorespiratory arrest related to the magnetic resonance imaging contrast agent gadobutrol has rarely been reported in the literature. Rarer is the association of hypokalemia with acidosis. We report 2 patients who had severe pulmonary edema associated with the use of gadobutrol contrast in the absence of other inciting agents or events. These cases were unique not only for their rare and severe presentations but also because they exemplified the increasing role of extracorporeal membrane oxygenation in resuscitation. Emergency extracorporeal membrane oxygenation resuscitation can be rapidly initiated and successful in the setting of a well-organized workflow, and it is a viable alternative and helps improve patient outcome in cases refractory to conventional resuscitative measures.

    Cardiac arrest has a high mortality in children. To improve the performance of cardiopulmonary resuscitation, it is essential to disseminate the international recommendations and the training of health professionals and the general population in resuscitation. This article summarises the 2015 European Paediatric Cardiopulmonary Resuscitation recommendations, which are based on a review of the advances in cardiopulmonary resuscitation and consensus in the science and treatment by the International Council on Resuscitation. The Spanish Paediatric Cardiopulmonary Resuscitation recommendations, developed by the Spanish Group of Paediatric and Neonatal Resuscitation, are an adaptation of the European recommendations, and will be used for training health professionals and the general population in resuscitation. This article highlights the main changes from the previous 2010 recommendations on prevention of cardiac arrest, the diagnosis of cardiac arrest, basic life support, advanced life support and post-resuscitation care, as well as reviewing the algorithms of treatment of basic life support, obstruction of the airway and advanced life support.

    Since the advent of cardiopulmonary resuscitation more than 40 years ago, we have achieved a return to spontaneous circulation in a growing proportion of patients with cardiac arrest. Nevertheless, most of these patients die in the first few days after admission to the intensive care unit (ICU), and this situation has not improved over the years. Mortality in these patients is mainly associated to brain damage. Perhaps recognizing that cardiopulmonary resuscitation does not end with the return of spontaneous circulation but rather with the return of normal brain function and total stabilization of the patient would help improve the therapeutic management of these patients in the ICU. In this sense, the term cardiocerebral resuscitation proposed by some authors might be more appropriate. The International Liaison Committee on Resuscitation recently published a consensus document on the "Post-Cardiac Arrest Syndrome" and diverse authors have proposed that post-arrest care be integrated as the fifth link in the survival chain, after early warning, early cardiopulmonary resuscitation by witnesses, early defibrillation, and early advanced life support. The therapeutic management of patients that recover spontaneous circulation after cardiopulmonary resuscitation maneuvers based on life support measures and a series of improvised actions based on "clinical judgment" might not be the best way to treat patients with post-cardiac arrest syndrome. Recent studies indicate that using goal-guided protocols to manage these patients including therapeutic measures of proven efficacy, such as inducing mild therapeutic hypothermia and early revascularization, when indicated, can improve the prognosis considerably in these patients. Given that there is no current protocol based on universally accepted evidence, the Steering Committee of the National Cardiopulmonary Resuscitation Plan of the Spanish Society of Intensive Medicine and Cardiac Units has elaborated this document after a

    Aim To analyze the initial rhythm, bystander cardiopulmonary resuscitation (CPR) rate, and survival after out-of-hospital cardiac arrests (OHCA) in Varaždin County (Croatia), and to investigate whether physician’s inexperience in emergency medical services (EMS) has an impact on resuscitation management. Methods We reviewed clinical records and Revised Utstein cardiac arrest forms of all out-of-hospital resuscitations performed by EMS Varaždin (EMSVz), Croatia, from 2007-2013. To analyze the impact of physician’s inexperience in EMS (<1 year in EMS) on resuscitation management, we assessed physician’s turnover in EMSVz, as well as OHCA survival, airway management, and adherence to resuscitation guidelines in regard to physician’s EMS experience. Results Of 276 patients (median age 68 years, interquartile range [IQR] 16; 198 male; 37% ventricular fibrillation/ventricular tachycardia, bystander CPR rate 25%), 80 were transferred to hospital and 39 were discharged (median survival after discharge 23 months, IQR 46 months). During the 7-year study period, 29 newly graduated physicians inexperienced in EMS started to work in EMSVz (performing 77 resuscitations), while 48% of them stayed for less than one year. Airway management depended on physician’s EMS experience (P = 0.018): inexperienced physicians performed bag-valve-mask ventilation (BMV) more than the experienced, with no impact on survival rate. Physician’s EMS experience did not influence adherence to resuscitation guidelines (P = 0.668), survival to hospital discharge (P = 0.791), or survival time (P = 0.405). Conclusion OHCA survival rate of EMSVz resuscitations was higher than in Europe, but bystander CPR needs to be improved. Compared to experienced physicians, inexperienced physicians preferred BMV over intubation, but with similar adherence to resuscitation guidelines and survival after OHCA. PMID:28051284

    Astronaut crew medical officers (CMO) aboard the International Space Station (ISS) receive 40 hours of medical training during the 18 months preceding each mission. Part of this training ilncludes twoperson cardiopulmonary resuscitation (CPR) per training guidelines from the American Heart Association (AHA). Recent studies concluded that the use of metronomic tones improves the coordination of CPR by trained clinicians. Similar data for bystander or "trained lay people" (e.g. CMO) performance of CPR (BCPR) have been limited. The purpose of this study was to evailuate whether use of timing devices, such as audible metronomic tones, would improve BCPR perfomance by trained bystanders. Twenty pairs of bystanders trained in two-person BCPR performled BCPR for 4 minutes on a simulated cardiopulmonary arrest patient using three interventions: 1) BCPR with no timing devices, 2) BCPR plus metronomic tones for coordinating compression rate only, 3) BCPR with a timing device and metronome for coordinating ventilation and compression rates, respectively. Bystanders were evaluated on their ability to meet international and AHA CPR guidelines. Bystanders failed to provide the recommended number of breaths and number of compressions in the absence of a timing device and in the presence of audible metronomic tones for only coordinating compression rate. Bystanders using timing devices to coordinate both components of BCPR provided the reco number of breaths and were closer to providing the recommended number of compressions compared with the other interventions. Survey results indicated that bystanders preferred to use a metronome for delivery of compressions during BCPR. BCPR performance is improved by timing devices that coordinate both compressions and breaths.

    Objective: To evaluate the effect of implementing real-time audiovisual feedback with and without postevent debriefing on survival and quality of cardiopulmonary resuscitation quality at in-hospital cardiac arrest. Design: A two-phase, multicentre prospective cohort study. Setting: Three UK hospitals, all part of one National Health Service Acute Trust. Patients: One thousand three hundred and ninety-five adult patients who sustained an in-hospital cardiac arrest at the study hospitals and were treated by hospital emergency teams between November 2009 and May 2013. Interventions: During phase 1, quality of cardiopulmonary resuscitation and patient outcomes were measured with no intervention implemented. During phase 2, staff at hospital 1 received real-time audiovisual feedback, whereas staff at hospital 2 received real-time audiovisual feedback supplemented by postevent debriefing. No intervention was implemented at hospital 3 during phase 2. Measurements and Main Results: The primary outcome was return of spontaneous circulation. Secondary endpoints included other patient-focused outcomes, such as survival to hospital discharge, and process-focused outcomes, such as chest compression depth. Random-effect logistic and linear regression models, adjusted for baseline patient characteristics, were used to analyze the effect of the interventions on study outcomes. In comparison with no intervention, neither real-time audiovisual feedback (adjusted odds ratio, 0.62; 95% CI, 0.31–1.22; p = 0.17) nor real-time audiovisual feedback supplemented by postevent debriefing (adjusted odds ratio, 0.65; 95% CI, 0.35–1.21; p = 0.17) was associated with a statistically significant improvement in return of spontaneous circulation or any process-focused outcome. Despite this, there was evidence of a system-wide improvement in phase 2, leading to improvements in return of spontaneous circulation (adjusted odds ratio, 1.87; 95% CI, 1.06–3.30; p = 0.03) and process

    Acute lung injury (ALI) frequently occurs in infants after cardiopulmonary bypass (CPB) surgery and it sometimes develops into acute respiratory distress syndrome in critically ill infants, which can be life threatening. This study investigated the effects of open lung ventilation on the haemodynamics and respiratory mechanics of 64 infants (34 males; 30 females) with a mean +/- SD age of 8.3 +/- 0.3 months who developed ALI following CPB surgery. Open lung ventilation significantly improved the respiratory mechanics and oxygenation parameters of the infants, including the partial pressure of oxygen in arterial blood (PaO(2)), the ratio of PaO(2)/FiO(2) (fraction of inspired oxygen), peak inspiratory pressure, static compliance and airway resistance. It is concluded that open lung ventilation can greatly improve oxygenation and respiratory mechanics in infants with ALI following CPB surgery.

    Drawings made by training children into cardiopulmonary resuscitation (CPR) during the special education week called "School otherwise" can be used as non-verbal means of expression and communication to assess the impact of such training. We analyzed the questionnaires and drawings completed by 327 schoolchildren in different stages of education. After a brief overview of the basic life support (BLS) steps and after watching a video presenting the dynamic performance of the BLS sequence, subjects were asked to complete a questionnaire and make a drawing to express main CPR messages. Questionnaires were filled completely in 97.6 % and drawings were done in 90.2 % cases. Half of the subjects had already witnessed a kind of medical emergency and 96.94 % knew the correct "112" emergency phone number. The drawings were single images (83.81 %) and less cartoon strips (16.18 %). Main themes of the slogans were "Save a life!", "Help!", "Call 112!", "Do not be indifferent/insensible/apathic!" through the use of drawings interpretation, CPR trainers can use art as a way to build a better relation with schoolchildren, to connect to their thoughts and feelings and obtain the highest quality education.

    Purpose Ineffective leadership during cardiopulmonary resuscitation (“code”) can negatively affect a patient’s likelihood of survival. In most teaching hospitals, internal medicine residents lead codes. In this study, the authors explored internal medicine residents’ experiences leading codes, with a particular focus on how gender influences the code leadership experience. Method The authors conducted individual, semi-structured telephone or in-person interviews with 25 residents (May 2012 to February 2013) from 9 U.S. internal medicine residency programs. They audio recorded and transcribed the interviews then thematically analyzed the transcribed text. Results Participants viewed a successful code as one with effective leadership. They agreed that the ideal code leader was an authoritative presence; spoke with a deep, loud voice; used clear, direct communication; and appeared calm. Although equally able to lead codes as their male colleagues, female participants described feeling stress from having to violate gender behavioral norms in the role of code leader. In response, some female participants adopted rituals to signal the suspension of gender norms while leading a code. Others apologized afterwards for their counter normative behavior. Conclusions Ideal code leadership embodies highly agentic, stereotypical male behaviors. Female residents employed strategies to better integrate the competing identities of code leader and female gender. In the future, residency training should acknowledge how female gender stereotypes may conflict with the behaviors required to enact code leadership and offer some strategies, such as those used by the female residents in this study, to help women integrate these dual identities.

    Cardiac arrest (CA) causes hippocampal neuronal death that frequently leads to severe loss of memory function in survivors. No specific treatment is available to reduce neuronal death and improve functional outcome. The brain's inflammatory response to ischemia can exacerbate injury and provides a potential treatment target. We hypothesized that microglia are activated by CA and contribute to neuronal loss. We used a mouse model to determine whether pharmacologic inhibition of the proinflammatory microglial enzyme soluble epoxide hydrolase (sEH) after CA alters microglial activation and neuronal death. The sEH inhibitor 4-phenylchalcone oxide (4-PCO) was administered after successful cardiopulmonary resuscitation (CPR). The 4-PCO treatment significantly reduced neuronal death and improved memory function after CA/CPR. We found early activation of microglia and increased expression of inflammatory tumor necrosis factor (TNF)-α and interleukin (IL)-1β in the hippocampus after CA/CPR, which was unchanged after 4-PCO treatment, while expression of antiinflammatory IL-10 increased significantly. We conclude that sEH inhibition after CA/CPR can alter the transcription profile in activated microglia to selectively induce antiinflammatory and neuroprotective IL-10 and reduce subsequent neuronal death. Switching microglial gene expression toward a neuroprotective phenotype is a promising new therapeutic approach for ischemic brain injury.

    Objectives To assess how the quality of metronome-guided cardiopulmonary resuscitation (CPR) was affected by the chest compression rate familiarised by training before the performance and to determine a possible mechanism for any effect shown. Design Prospective crossover trial of a simulated, one-person, chest-compression-only CPR. Setting Participants were recruited from a medical school and two paramedic schools of South Korea. Participants 42 senior students of a medical school and two paramedic schools were enrolled but five dropped out due to physical restraints. Intervention Senior medical and paramedic students performed 1 min of metronome-guided CPR with chest compressions only at a speed of 120 compressions/min after training for chest compression with three different rates (100, 120 and 140 compressions/min). Friedman's test was used to compare average compression depths based on the different rates used during training. Results Average compression depths were significantly different according to the rate used in training (p<0.001). A post hoc analysis showed that average compression depths were significantly different between trials after training at a speed of 100 compressions/min and those at speeds of 120 and 140 compressions/min (both p<0.001). Conclusions The depth of chest compression during metronome-guided CPR is affected by the relative difference between the rate of metronome guidance and the chest compression rate practised in previous training.

    During the initial assessment of the injured athlete, the Sports Physical Therapist (PT) must first be concerned with life-threatening emergencies such as absence of breathing and pulse. The sports PT must also be aware of the possibility of "sudden cardiac death" that could occur in others, including coaches, officials, and fans. If the PT assumes the role of "most medical" person at the contest or event, the responsibility for life saving action falls squarely on their shoulders. Therefore, skills and ongoing certification in cardio- pulmonary resuscitation techniques and the use of an automated external defibrillator are a basic necessity. These skills are required as part of the specialty practice of sports PT (BLS Healthcare Provider course or CPR for the Professional Rescuer in addition to completion of the First Responder Course OR credentials as an EMT or ATC), and are mandatory for being qualified to sit for the exam to become a sports certified specialist (SCS) by the American Board of Physical Therapy Specialties (ABPTS).(3).

    Background The impact of dispatcher‐assisted bystander cardiopulmonary resuscitation (CPR) on neurological outcomes in children is unclear. We investigated whether dispatcher‐assisted bystander CPR shows favorable neurological outcomes (Cerebral Performance Category scale 1 or 2) in children with out‐of‐hospital cardiac arrest (OHCA). Methods and Results Children (n=5009, age<18 years) with OHCA were selected from a nationwide Utstein‐style Japanese database (2008–2010) and divided into 3 groups: no bystander CPR (n=2287); bystander CPR with dispatcher instruction (n=2019); and bystander CPR without dispatcher instruction (n=703) groups. The primary endpoint was favorable neurological outcome at 1 month post‐OHCA. Dispatcher CPR instruction was offered to 53.9% of patients, significantly increasing bystander CPR provision rate (adjusted odds ratio [aOR], 7.51; 95% confidence interval [CI], 6.60 to 8.57). Bystander CPR with and without dispatcher instruction were significantly associated with improved 1‐month favorable neurological outcomes (aOR, 1.81 and 1.68; 95% CI, 1.24 to 2.67 and 1.07 to 2.62, respectively), compared to no bystander CPR. Conventional CPR was associated with increased odds of 1‐month favorable neurological outcomes irrespective of etiology of cardiac arrest (aOR, 2.30; 95% CI, 1.56 to 3.41). However, chest‐compression‐only CPR was not associated with 1‐month meaningful outcomes (aOR, 1.05; 95% CI, 0.67 to 1.64). Conclusions In children with OHCA, dispatcher‐assisted bystander CPR increased bystander CPR provision rate and was associated with improved 1‐month favorable neurological outcomes, compared to no bystander CPR. Conventional bystander CPR was associated with greater likelihood of neurologically intact survival, compared to chest‐compression‐only CPR, irrespective of cardiac arrest etiology. PMID:24785780

    Our objective was to compare the impact of a training program in pediatric cardiopulmonary resuscitation (CPR) on the knowledge and skills of in-service and preservice nurses at prespecified time points. This repeated-measures quasiexperimental study was conducted in the pediatric emergency and ICU of a tertiary care teaching hospital between January and March 2011. We assessed the baseline knowledge and skills of nursing staff (in-service nurses) and final year undergraduate nursing students (preservice nurses) using a validated questionnaire and a skill checklist, respectively. The participants were then trained on pediatric CPR using standard guidelines. The knowledge and skills were reassessed immediately after training and at 6 weeks after training. A total of 74 participants-28 in-service and 46 preservice professionals-were enrolled. At initial assessment, in-service nurses were found to have insignificant higher mean knowledge scores (6.6 versus 5.8, P = 0.08) while the preservice nurses had significantly higher skill scores (6.5 versus 3.2, P < 0.001). Immediately after training, the scores improved in both groups. At 6 weeks however, we observed a nonuniform decline in performance in both groups-in-service nurses performing better in knowledge test (10.5 versus 9.1, P = 0.01) and the preservice nurses performing better in skill test (9.8 versus 7.4, P < 0.001). Thus, knowledge and skills of in-service and preservice nurses in pediatric CPR improved with training. In comparison to preservice nurses, the in-service nurses seemed to retain knowledge better with time than skills.

    Cardiopulmonary bypass (CPB) management in neonates, infants, and children requires extensive alterations in temperature, pump flow rate, and perfusion pressure, with occasional periods of circulatory arrest. The effect of these alterations on cerebral blood flow (CBF) are unknown. This study was designed to determine the relation of temperature and mean arterial pressure to CBF during hypothermic CPB (18-32{degrees}C), with and without periods of total circulatory arrest. CBF was measured before, during, and after hypothermic CPB with xenon-clearance techniques in 67 pediatric patients, aged 1 day-16 years. Patients were grouped based on different CPB techniques: group A, repair during moderate-hypothermic bypass at 25-32{degrees}C; group B, repair during deep-hypothermic bypass at 18-22{degrees}C; and group C, repair with total circulatory arrest at 18{degrees}C. There was a significant correlation of CBF with temperature during CPB. CBF significantly decreased under hypothermic conditions in all groups compared with prebypass levels under normothermia. In groups A and B, CBF returned to baseline levels in the rewarming phase of CPB and exceeded baseline levels after bypass. In group C, no significant increase in CBF was observed during rewarming after total circulatory arrest (32 {plus minus} 12 minutes) or after weaning from CPB. During moderate-hypothermic CPB (25-32{degrees}C), there was no association between CBF and mean arterial pressure. However, during deep-hypothermic CPB (18-22{degrees}C), there was a association between CBF and mean arterial pressure.

    It is rare for newborn infants to require prolonged resuscitation at birth. While there are detailed national and international guidelines on when and how to provide resuscitation to newborns, there is little existing guidance on when newborn resuscitation should be stopped. In this paper we review current guidance surrounding adult, paediatric and neonatal resuscitation as well as recent evidence of outcome for newborn infants requiring prolonged resuscitation. We discuss the ethical principles that can potentially guide decisions surrounding resuscitation and post-resuscitation care. We also propose a structured approach to stopping resuscitation.

    At birth approximately 10 % of term or near-term neonates require initial stabilization maneuvers to establish a cry or regular breathing, maintain a heart rate greater than 100 beats per minute (bpm), and good color and muscular tone. About 1 % requires ventilation and very few infants receive chest compressions or medication. However, birth asphyxia is a worldwide problem and can lead to death or serious sequelae. Recently, the European Resuscitation Council (ERC) and the International Liaison Committee on Resuscitation (ILCOR) published new guidelines on resuscitation at birth. These guidelines review specific questions such as the use of air or 100 % oxygen in the delivery room, dose and routes of adrenaline delivery, the peripartum management of meconium-stained amniotic fluid, and temperature control. Assisted ventilation in preterm infants is briefly described. New devices to improve the care of newborn infants, such as the laryngeal mask airway or CO2 detectors to confirm tracheal tube placement, are also discussed. Significant changes have occurred in some practices and are included in this document.

    Introduction Current prevalence estimates of gastrostomy tube (GT) /tracheostomy placement in hospitalized patients with anoxic/hypoxic ischemic encephalopathic injury (AHIE) post cardiopulmonary resuscitation (CPR) are unknown. We sought, to estimate the prevalence of AHIE in hospitalized patients who had CPR and to identify patient/hospital level factors that predict the performance of GT/tracheostomy in those with AHIE. Methods We performed a retrospective analysis of the Nationwide Inpatient Sample (years 2004–2010). All patients who developed AHIE following CPR were included. In this cohort the odds of having GT and tracheostomy was computed by multivariable logistic regression analysis. Patient and hospital level factors were the independent variables. Results During the study period, a total of 686,578 CPR events occurred in hospitalized patients. Of these, 94,336 (13.7%) patients developed AHIE. In this AHIE cohort, 6.8% received GT and 8.3% tracheostomy. When compared to the 40–49 yrs age group, those aged >70 yrs were associated with lower odds for GT (OR = 0.65, 95% CI:0.53–0.80, p<0.0001). Those aged <18 years & those >60 years were associated with lower odds for having tracheostomy when compared to the 40–49 years group (p<0.0001). Each one unit increase in co-morbid burden was associated with higher odds for having GT (OR = 1.23,p<0.0001) or tracheostomy (OR = 1.17, p<0.0001). Blacks, Hispanics, Asians/Pacific Islanders, and other races were associated with higher odds for having GT or tracheostomy when compared to whites (p<0.05). Hospitals located in northeastern regions were associated with higher odds for performing GT (OR = 1.48, p<0.0001) or tracheostomy (OR = 1.63, p<0.0001) when compared to those in Western regions. Teaching hospitals (TH) were associated with higher odds for performing tracheostomy when compared to non-TH (OR = 1.36, 1.20–1.54, p<0.0001). Conclusions AHIE injury occurs in a significant number of in-hospital arrests

    Background During pediatric cardiopulmonary resuscitation (CPR), vasoactive drug preparation for continuous infusion is both complex and time-consuming, placing children at higher risk than adults for medication errors. Following an evidence-based ergonomic-driven approach, we developed a mobile device app called Pediatric Accurate Medication in Emergency Situations (PedAMINES), intended to guide caregivers step-by-step from preparation to delivery of drugs requiring continuous infusion. Objective The aim of our study was to determine whether the use of PedAMINES reduces drug preparation time (TDP) and time to delivery (TDD; primary outcome), as well as medication errors (secondary outcomes) when compared with conventional preparation methods. Methods The study was a randomized controlled crossover trial with 2 parallel groups comparing PedAMINES with a conventional and internationally used drugs infusion rate table in the preparation of continuous drug infusion. We used a simulation-based pediatric CPR cardiac arrest scenario with a high-fidelity manikin in the shock room of a tertiary care pediatric emergency department. After epinephrine-induced return of spontaneous circulation, pediatric emergency nurses were first asked to prepare a continuous infusion of dopamine, using either PedAMINES (intervention group) or the infusion table (control group), and second, a continuous infusion of norepinephrine by crossing the procedure. The primary outcome was the elapsed time in seconds, in each allocation group, from the oral prescription by the physician to TDD by the nurse. TDD included TDP. The secondary outcome was the medication dosage error rate during the sequence from drug preparation to drug injection. Results A total of 20 nurses were randomized into 2 groups. During the first study period, mean TDP while using PedAMINES and conventional preparation methods was 128.1 s (95% CI 102-154) and 308.1 s (95% CI 216-400), respectively (180 s reduction, P=.002).

    Background Sustained lung inflations (SLI) during neonatal resuscitation may promote alveolar recruitment in preterm infants. While most of the studies focus on respiratory outcome, the impact of SLI on the brain hasn’t been investigated yet. Objective Do SLI affect cerebral blood volume (CBV) in preterm infants? Methods Preterm infants of gestation 28 weeks 0 days to 33 weeks 6 days with requirement for respiratory support (RS) were included in this randomized controlled pilot trial. Within the first 15 minutes after birth near-infrared spectroscopy (NIRS) measurements using ‘NIRO-200-NX’ (Hamamatsu, Japan) were performed to evaluate changes in CBV and cerebral tissue oxygenation. Two groups were compared based on RS: In SLI group RS was given by applying 1–3 SLI (30 cmH2O for 15 s) continued by respiratory standard care. Control group received respiratory standard care only. Results 40 infants (20 in each group) with mean gestational age of 32 weeks one day (±2 days) and birth weight of 1707 (±470) g were included. In the control group ΔCBV was significantly decreasing, whereas in SLI group ΔCBV showed similar values during the whole period of 15 minutes. Comparing both groups within the first 15 minutes ΔCBV showed a tendency toward different overall courses (p = 0.051). Conclusion This is the first study demonstrating an impact of SLI on CBV. Further studies are warranted including reconfirmation of the present findings in infants with lower gestational age. Future investigations on SLI should not only focus on respiratory outcome but also on the consequences on the developing brain.

    Cardiopulmonary resuscitation (CPR) is an essential skill taught within undergraduate nursing programmes. At the author's institution, students must pass the CPR objective structured clinical examination (OSCE) before progressing to second year. However, some students have difficulties developing competence in CPR and evidence suggests that resuscitation skills may only be retained for several months. This has implications for practice as nurses are required to be competent in CPR. Therefore, further opportunities for students to develop these skills are necessary. An action research project was conducted with six students who were assessed by an examiner at a video-recorded mock OSCE. Students self-assessed their skills using the video and a checklist. Semi-structured interviews were conducted to compare checklist scores, and explore students' thoughts and experiences of the OSCE. The findings indicate that students may need to repeat this exercise by comparing their previous and current performances to develop both their self-assessment and CPR skills. Although there were some differences between the examiner's and student's checklist scores, all students reported the benefits of participating in this project, e.g. discussion and identification of knowledge and skills deficits, thus emphasising the benefits of formative assessments to prepare students for summative assessments and ultimately clinical practice.

    Background Optimizing resuscitation is important to prevent morbidity and mortality from perinatal asphyxia. The metabolism of cells and tissues is severely disturbed during asphyxia and resuscitation, and metabolomic analyses provide a snapshot of many small molecular weight metabolites in body fluids or tissues. In this study metabolomics profiles were studied in newborn pigs that were asphyxiated and resuscitated using different protocols to identify biomarkers for subject characterization, intervention effects and possibly prognosis. Methods A total of 125 newborn Noroc pigs were anesthetized, mechanically ventilated and inflicted progressive asphyxia until asystole. Pigs were randomized to resuscitation with a FiO2 0.21 or 1.0, different duration of ventilation before initiation of chest compressions (CC), and different CC to ventilation ratios. Plasma and urine samples were obtained at baseline, and 2 h and 4 h after return of spontaneous circulation (ROSC, heart rate > = 100 bpm). Metabolomics profiles of the samples were analyzed by nuclear magnetic resonance spectroscopy. Results Plasma and urine showed severe metabolic alterations consistent with hypoxia and acidosis 2 h and 4 h after ROSC. Baseline plasma hypoxanthine and lipoprotein concentrations were inversely correlated to the duration of hypoxia sustained before asystole occurred, but there was no evidence for a differential metabolic response to the different resuscitation protocols or in terms of survival. Conclusions Metabolic profiles of asphyxiated newborn pigs showed severe metabolic alterations. Consistent with previously published reports, we found no evidence of differences between established and alternative resuscitation protocols. Lactate and pyruvate may have a prognostic value, but have to be independently confirmed. PMID:27529347

    Background Triiodothyronine levels decrease in infants and children after cardiopulmonary bypass. We tested the primary hypothesis that triiodothyronine (T3) repletion is safe in this population and produces improvements in postoperative clinical outcome. Methods and Results The TRICC study was a prospective, multicenter, double-blind, randomized, placebo-controlled trial in children younger than 2 years old undergoing heart surgery with cardiopulmonary bypass. Enrollment was stratified by surgical diagnosis. Time to extubation (TTE) was the primary outcome. Patients received intravenous T3 as Triostat (n=98) or placebo (n=95), and data were analyzed using Cox proportional hazards. Overall, TTE was similar between groups. There were no differences in adverse event rates, including arrhythmia. Prespecified analyses showed a significant interaction between age and treatment (P=0.0012). For patients younger than 5 months, the hazard ratio (chance of extubation) for Triostat was 1.72. (P=0.0216). Placebo median TTE was 98 hours with 95% confidence interval (CI) of 71 to 142 compared to Triostat TTE at 55 hours with CI of 44 to 92. TTE shortening corresponded to a reduction in inotropic agent use and improvement in cardiac function. For children 5 months of age, or older, Triostat produced a significant delay in median TTE: 16 hours (CI, 7–22) for placebo and 20 hours (CI, 16–45) for Triostat and (hazard ratio, 0.60; P=0.0220). Conclusions T3 supplementation is safe. Analyses using age stratification indicate that T3 supplementation provides clinical advantages in patients younger than 5 months and no benefit for those older than 5 months.

  8. Are chest compressions safe for the patient reconstructed with sternal plates? Evaluating the safety of cardiopulmonary resuscitation using a human cadaveric model

    PubMed Central

    2010-01-01

    Background Plate and screw fixation is a recent addition to the sternal wound treatment armamentarium. Patients undergoing cardiac and major vascular surgery have a higher risk of postoperative arrest than other elective patients. Those who undergo sternotomy for either cardiac or major vascular procedures are at a higher risk of postoperative arrest. Sternal plate design allows quick access to the mediastinum facilitating open cardiac massage, but chest compressions are the mainstay of re-establishing cardiac output in the event of arrest. The response of sternal plates and the chest wall to compressions when plated has not been studied. The safety of performing this maneuver is unknown. This study intends to demonstrate compressions are safe after sternal plating. Methods We investigated the effect of chest compressions on the plated sternum using a human cadaveric model. Cadavers were plated, an arrest was simulated, and an experienced physician performed a simulated resuscitation. Intrathoracic pressure was monitored throughout to ensure the plates encountered an appropriate degree of force. The hardware and viscera were evaluated for failure and trauma respectively. Results No hardware failure or obvious visceral trauma was observed. Rib fractures beyond the boundaries of the plates were noted but the incidence was comparable to control and to the fracture incidence after resuscitation previously cited in the literature. Conclusions From this work we believe chest compressions are safe for the patient with sternal plates when proper plating technique is used. We advocate the use of this life-saving maneuver as part of an ACLS resuscitation in the event of an arrest for rapidly re-establishing circulation. PMID:20718981

    Objective This pilot study assesses the degree of hemolysis induced by cardiopulmonary bypass (CPB) and determines its association with acute kidney injury (AKI) in pediatric patients. Further, it evaluates the degree to which the use of urinary biomarkers neutrophil gelatinase-associated lipocalin (NGAL) and cystatin C correlate with the presence of AKI and hemolysis following CPB. Design Prospective observational study Setting A 13-bed pediatric cardiac intensive care unit in a university hospital Patients Children undergoing cardiac surgery with the use of CPB Interventions None Measurements and Main Results Blood and urine samples were obtained at multiple time points before and after CPB. Hemolysis was assessed by measuring levels of plasma hemoglobin and haptoglobin. AKI was defined as a doubling in serum creatinine from preoperative baseline and by using the pediatric-modified RIFLE criteria. Urinary NGAL and Cystatin C levels were measured. A total of 40 patients (range: 3 days to 4.8 years) were enrolled. Plasma hemoglobin levels increased markedly on separation from CPB with a concurrent decrease in haptoglobin. This was associated with an increase in protein oxidation in the plasma. Hemolysis was more evident in younger patients with a longer duration of bypass and in those requiring a blood-primed circuit. 40% of patients had a doubling in serum creatinine and 88% of patients developed acute kidney injury when defined by the pediatric-modified RIFLE criteria. Controlling for CPB time, persistently elevated levels of plasma hemoglobin were associated with a 5 fold increase in AKI. Further, urinary NGAL measured 2 hours after separation from CPB was associated with AKI and with elevations in plasma hemoglobin. Conclusions CPB in pediatric patients results in significant hemolysis, which is associated with the development of AKI. The biomarker NGAL correlates with both AKI and hemolysis in this population.

    Purpose. Rapid advanced airway management is important in maternal cardiopulmonary resuscitation (CPR). This study aimed to compare intubation performances among Pentax-AWS (AWS), Glidescope (GVL), and Macintosh laryngoscope (MCL) during mechanical chest compression in 15° and 30° left lateral tilt. Methods. In 19 emergency physicians, a prospective randomized crossover study was conducted to examine the three laryngoscopes. Primary outcomes were the intubation time and the success rate for intubation. Results. The median intubation time using AWS was shorter than that of GVL and MCL in both tilt degrees. The time to visualize the glottic view in GVL and AWS was significantly lower than that of MCL (all P < 0.05), whereas there was no significant difference between the two video laryngoscopes (in 15° tilt, P = 1; in 30° tilt, P = 0.71). The progression of tracheal tube using AWS was faster than that of MCL and GVL in both degrees (all P < 0.001). Intubations using AWS and GVL showed higher success rate than that of Macintosh laryngoscopes. Conclusions. The AWS could be an appropriate laryngoscope for airway management of pregnant women in tilt CPR considering intubation time and success rate. PMID:26161426

    Laryngeal Mask Airway (LMA) has been indicated as an effective device for airway management when face-mask ventilation and intubation have both failed in infants weighing >2000 g or delivered ≥34 weeks of gestation. All previous studies used a classic LMA. The current report describes the first case of a very low birthweight infant (1470 g, <3rd centile; 36+3gestational weeks) with micrognathia and palate cleft with Cornelia De Lange syndrome, resuscitated at birth with a new supraglottic airway device, i-gel size-1, positioned by a trainee paediatrician at first attempt. The procedure allowed reaching prompt effective ventilation and oxygenation of the patient, who was stabilised and intubated through i-gel. PMID:25809435

    Objective Our aim was to compare the compression quality, exercise intensity, and energy expenditure in 5-minute single-rescuer cardiopulmonary resuscitation (CPR) using 15:1 or 30:2 compression-to-ventilation (C:V) ratios or chest compression only (CCO). Methods This was a randomized, crossover manikin study. Medical students were randomized to perform either type of CPR and do the others with intervals of at least 1 day. We measured compression quality, ratings of perceived exertion (RPE) score, heart rate, maximal oxygen uptake, and energy expenditure during CPR. Results Forty-seven students were recruited. Mean compression rates did not differ between the 3 groups. However, the mean percentage of adequate compressions in the CCO group was significantly lower than that of the 15:1 or 30:2 group (31.2±30.3% vs. 55.1±37.5% vs. 54.0±36.9%, respectively; P<0.001) and the difference occurred within the first minute. The RPE score in each minute and heart rate change in the CCO group was significantly higher than those of the C:V ratio groups. There was no significant difference in maximal oxygen uptake between the 3 groups. Energy expenditure in the CCO group was relatively lower than that of the 2 C:V ratio groups. Conclusion CPR using a 15:1 C:V ratio may provide a compression quality and exercise intensity comparable to those obtained using a 30:2 C:V ratio. An earlier decrease in compression quality and increase in RPE and heart rate could be produced by CCO CPR compared with 15:1 or 30:2 C:V ratios with relatively lower oxygen uptake and energy expenditure.

    Sudden death due to cardiac arrest represents one of the greatest challenges facing modern medicine, not only because of the massive number of cases involved but also because of its tremendous social and economic impact. For many years, the magic figure of 1 per 1000 inhabitants per year was generally accepted as an estimate of the annual incidence of sudden death in the industrialized world, with a survival rate of 6 %. This estimate was based on large numbers of published reports of local, regional, national and multinational experience in the management of cardiac arrest. Measuring the global incidence of cardiac arrest is challenging as many different definitions of patient populations are used. Randomized controlled trials (RCT) provide insights into the value of specific treatments or treatment strategies in a well-defined section of a population. Registries do not compete with clinical studies, but represent a useful supplement to them. Surveys and registries provide insights into the ways in which scientific findings and guidelines are being implemented in clinical practice. However, as with clinical studies, comprehensive preparations are needed in order to establish a registry. This is all the more decisive because not all of the questions that may arise are known at the time when the registry is established. The German resuscitation registry started in May 2007 and currently more than 230 paramedic services and hospitals take part. More than 45,000 cases of out-of-hospital cardiac arrest and in-hospital cardiac arrest are included. With this background the German resuscitation registry is one of the largest databases in emergency medicine in Germany. After 5 years of running the preclinical care dataset was revised in 2012. Data variables that reflect current or new treatment were added to the registry. The postresuscitation basic care and telephone cardiopulmonary resuscitation (CPR) datasets were developed in 2012 and 2013 as well. The German

    Background Cardiopulmonary resuscitation (CPR) is an intervention used in cases of cardiac arrest to revive patients whose heart has stopped. Because cardiac arrest can have potentially devastating outcomes such as severe neurological deficits even if CPR is performed, patients must be involved in determining in advance if they want CPR in the case of an unexpected arrest. Shared decision making (SDM) facilitates discussions about goals of care regarding CPR in intensive care units (ICUs). Patient decision aids (DAs) are proven to support the implementation of SDM. Many patient DAs about CPR exist, but they are not universally implemented in ICUs in part due to lack of context and cultural adaptation. Adaptation to local context is an important phase of implementing any type of knowledge tool such as patient DAs. User-centered design supported by a wiki platform to perform rapid prototyping has previously been successful in creating knowledge tools adapted to the needs of patients and health professionals (eg, asthma action plans). This project aims to explore how user-centered design and a wiki platform can support the adaptation of an existing DA for CPR to the local context. Objective The primary objective is to use an existing DA about CPR to create a wiki-based DA that is adapted to the context of a single ICU and tailorable to individual patient’s risk factors while employing user-centered design. The secondary objective is to document the use of a wiki platform for the adaptation of patient DAs. Methods This study will be conducted in a mixed surgical and medical ICU at Hôtel-Dieu de Lévis, Quebec, Canada. We plan to involve all 5 intensivists and recruit at least 20 alert and oriented patients admitted to the ICU and their family members if available. In the first phase of this study, we will observe 3 weeks of daily interactions between patients, families, intensivists, and other allied health professionals. We will specifically observe 5 dyads of

    Triiodothyronine (T3) supplementation improves clinical outcomes in infants after cardiac surgery using cardiopulmonary bypass by unknown mechanisms. We utilized a translational model of infant cardiopulmonary bypass to test the hypothesis that T3 modulates pyruvate entry into the citric acid cycle (CAC), thereby providing the energy support for improved cardiac function after ischemia-reperfusion (I/R). Neonatal piglets received intracoronary [2-(13)Carbon((13)C)]pyruvate for 40 min (8 mM) during control aerobic conditions (control) or immediately after reperfusion (I/R) from global hypothermic ischemia. A third group (I/R-Tr) received T3 (1.2 μg/kg) during reperfusion. We assessed absolute CAC intermediate levels and flux parameters into the CAC through oxidative pyruvate decarboxylation (PDC) and anaplerotic carboxylation (PC) using [2-(13)C]pyruvate and isotopomer analysis by gas and liquid chromatography-mass spectrometry and (13)C-nuclear magnetic resonance spectroscopy. When compared with I/R, T3 (group I/R-Tr) increased cardiac power and oxygen consumption after I/R while elevating flux of both PDC and PC (∼4-fold). Although neither I/R nor I/R-Tr modified absolute CAC levels, T3 inhibited I/R-induced reductions in their molar percent enrichment. Furthermore, (13)C-labeling of CAC intermediates suggests that T3 may decrease entry of unlabeled carbons at the level of oxaloacetate through anaplerosis or exchange reaction with asparate. T3 markedly enhances PC and PDC fluxes, thereby providing potential substrate for elevated cardiac function after reperfusion. This T3-induced increase in pyruvate fluxes occurs with preservation of the CAC intermediate pool. Our labeling data raise the possibility that T3 reduces reliance on amino acids for anaplerosis after reperfusion.

    The modern treatment of cardiac arrest is an increasingly complex medical procedure with a rapidly changing array of therapeutic approaches designed to restore life to victims of sudden death. The 2 primary goals of providing artificial circulation and defibrillation to halt ventricular fibrillation remain of paramount importance for saving lives. They have undergone significant improvements in technology and dissemination into the community subsequent to their establishment 60 years ago. The evolution of artificial circulation includes efforts to optimize manual cardiopulmonary resuscitation, external mechanical cardiopulmonary resuscitation devices designed to augment circulation, and may soon advance further into the rapid deployment of specially designed internal emergency cardiopulmonary bypass devices. The development of defibrillation technologies has progressed from bulky internal defibrillators paddles applied directly to the heart, to manually controlled external defibrillators, to automatic external defibrillators that can now be obtained over-the-counter for widespread use in the community or home. But the modern treatment of cardiac arrest now involves more than merely providing circulation and defibrillation. As suggested by a 3-phase model of treatment, newer approaches targeting patients who have had a more prolonged cardiac arrest include treatment of the metabolic phase of cardiac arrest with therapeutic hypothermia, agents to treat or prevent reperfusion injury, new strategies specifically focused on pulseless electric activity, which is the presenting rhythm in at least one third of cardiac arrests, and aggressive post resuscitation care. There are discoveries at the cellular and molecular level about ischemia and reperfusion pathobiology that may be translated into future new therapies. On the near horizon is the combination of advanced cardiopulmonary bypass plus a cocktail of multiple agents targeted at restoration of normal metabolism and

    Suspended animation is defined as the therapeutic induction of a state of tolerance to temporary complete systemic ischemia, i.w., protection-preservation of the whole organism during prolonged circulatory arrest ( > or = 1 hr), followed by resuscitation to survival without brain damage. The objectives of suspended animation include: a) helping to save victims of temporarily uncontrollable (internal) traumatic (e.g., combat casualties) or nontraumatic (e.g., ruptured aortic aneurysm) exsanguination, without severe brain trauma, by enabling evacuation and resuscitative surgery during circulatory arrest, followed by delayed resuscitation; b) helping to save some nontraumatic cases of sudden death, seemingly unresuscitable before definite repair; and c) enabling selected (elective) surgical procedures to be performed which are only feasible during a state of no blood flow. In the discussion session, investigators with suspended animation-relevant research interests brainstorm on present knowledge, future research potentials, and the advisability of a major research effort concerning this subject. The following topics are addressed: the epidemiologic facts of sudden death in combat casualties, which require a totally new resuscitative approach; the limits and potentials of reanimation research; complete reversibility of circulatory arrest of 1 hr in dogs under profound hypothermia ( < 10 degrees C), induced and reversed by portable cardiopulmonary bypass; the need for a still elusive pharmacologic or chemical induction of suspended animation in the field; asanguinous profound hypothermic low-flow with cardiopulmonary bypass; electric anesthesia; opiate therapy; lessons learned by hypoxia tolerant vertebrate animals, hibernators, and freeze-tolerant animals (cryobiology); myocardial preservation during open-heart surgery; organ preservation for transplantation; and reperfusion-reoxygenation injury in vital organs, including the roles of nitric oxide and free radicals

    Cardiac arrest is a major public health problem affecting thousands of individuals each year in both the before hospital and in-hospital settings. However, although the scope of the problem is large, the quality of care provided during resuscitation attempts frequently does not meet quality of care standards, despite evidence-based cardiopulmonary resuscitation (CPR) guidelines, extensive provider training, and provider credentialing in resuscitation medicine. Although this fact may be disappointing, it should not be surprising. Resuscitation of the cardiac arrest victim is a highly complex task requiring coordination between various levels and disciplines of care providers during a stressful and relatively infrequent clinical situation. Moreover, it requires a targeted, high-quality response to improve clinical outcomes of patients. Therefore, solutions to improve care provided during resuscitation attempts must be multifaceted and targeted to the diverse number of care providers to be successful. PMID:22107978

    Dispatch-assisted bystander cardiopulmonary resuscitation in out-of-hospital cardiac arrest has been shown as an effective measure to improve the survival of this process. The development of a unified protocol for all dispatch centers of the different emergency medical services can be a first step towards this goal in our environment. The process of developing a recommendations document and the realization of posters of dispatch-assisted cardiopulmonary resuscitation, agreed by different actors and promoted by the Spanish Resuscitation Council, is presented.

    The extent to which Emergency Medical Service personnel are placed in situations in which difficult cardiopulmonary resuscitation decisions must be made has been poorly explored. Further, it is not known whether this kind of decision making is troubling to emergency medical technicians. Although it is likely that emergency medical service systems handle withholding cardiopulmonary resuscitation in a variety of ways, the authors chose to examine a cross-section of New Mexico emergency medical technicians. Using a survey instrument, emergency medical technicians of all training levels, representing several emergency medical service systems around the state were asked how many times in their career they had been in a situation in which cardiopulmonary resuscitation had been withheld without a direct physician order. Of 310 individuals surveyed, 211 (66.8%) responded that this had occurred at least once. When asked whether they had been troubled by one of these situations, 86 of 211 (41%) individuals responded "yes." When a variety of demographic factors were evaluated, only training to the paramedic level was identified as being an independent predictor of those who were troubled (P = .019). Emergency medical technician training, protocols, and do not resuscitate programs may need to be expanded to give further guidance to prehospital personnel when making difficult resuscitation decisions.

    Acute poisonings in USA are a leading cause of cardiac arrest, especially in youngsters. Primary survey and cardiopulmonary resuscitation for poisoning is based on ABCDE procedure. One of the most common manifestation of acute poisoning is coma. An open airway should be ensured. Endotracheal intubation should be performed by an experienced person. The mouth-to mouth method of artificial respiration can be applied ultimately. In case of cyanide, hydrogen sulfide, organophosphates and corrosives poisonings a special caution is needed and pocket mask or self-inflating bag with a face mask should be rather used. A quick poison identification and a contact with regional poison information centre regarding patient management are crucial. Different procedures include prolonged cardiopulmonary resuscitation.

    PubMed/MEDLINE (1966-November 2014) was searched to identify relevant published studies on the overall frequency, types, and examples of medication errors during medical emergencies involving cardiopulmonary resuscitation and related situations, and the breakdown by type of error. The overall frequency of medication errors during medical emergencies, specifically situations related to resuscitation, is highly variable. Medication errors during such emergencies, particularly cardiopulmonary resuscitation and surrounding events, are not well characterized in the literature but may be more frequent than previously thought. Depending on whether research methods included database mining, simulation, or prospective observation of clinical practice, reported occurrence of medication errors during cardiopulmonary resuscitation and surrounding events has ranged from less than 1% to 50%. Because of the chaos of the resuscitation environment, errors in prescribing, dosing, preparing, labeling, and administering drugs are prone to occur. System-based strategies, such as infusion pump policies and code cart management, as well as personal strategies exist to minimize medication errors during emergency situations.

    Attempt to resuscitate asphyxiated neonates dates back to 1940's described in the Japanese obstetric textbook. These resuscitation methods simply employed moving the chest by applying external forces, such as bending the torso or flipping over the baby's body. In 1953, Virginia Apgar, an obstetric anesthesiologist, proposed her score to assess newborn status, which has been used worldwide thereafter. American Academy of Pediatrics and American Heart Association developed neonatal resuscitation guidelines in 1980's, the most recent guideline having been issued in 2005. The Japanese Society of Perinatal and Neonatal Medicine modified this guideline and started training courses for neonatal cardiopulmonary resuscitation (NCPR). Many resuscitation skills and medications are familiar to anesthesiologists, and many anesthesiologists are expected to be certified in NCPR in the future. Guideline is to be revised on regular basis, as the scientific and clinical evidence accumulates, and the next one will likely recommend reduced FI(O2) during resuscitation.

    In Mexico, out-of-hospital cardiac arrest is a health problem that represents 33,000 to 150,000 or more deaths per year. The few existent reports show mortality as high as 100% in contrast to some international reports that show higher survival rates. In Queretaro, during the last 5 years there were no successful resuscitation cases. However, in 2012 some patients were reported to have return of spontaneous circulation. We report in this article 3 cases with return of spontaneous circulation and pulse at arrival to the hospital. Two of the patients were discharged alive, one of them with poor cerebral performance category. Community cardiopulmonary resuscitation, early defibrillation and better emergency medical system response times, are related with survival. This poorly explored health problem in Queretaro could be increased with quality and good public education, bystander assisted cardiopulmonary resuscitation, police involvement in cardiopulmonary resuscitation and defibrillation, public access defibrillation programs and measurement of indicators and feedback for better results.

    Medicolegal issues in cardiopulmonary resuscitation (CPR) and emergency cardiac care were considered in the United States by the National Conference on Cardiopulmonary Resuscitation in 1985. This paper discusses these issues in the Canadian context. Although there is little legislation or case precedent in Canada to guide providers of CPR in decision-making, there appears to be little risk of liability or prosecution for competently rendered care. Providers should be cautious in withholding or withdrawing resuscitative measures from incompetent patients when brain death has not occurred and cardiovascular unresponsiveness has not been demonstrated. However, resuscitation may be withheld when a competent patient refuses it or if there is another medically and legally valid reason to do so. PMID:2644006

    Cardiovascular diseases are still the most common cause of death, and heart failure is the most common reason for hospitalization of patients older than 65 years. However, Cardiology attributes low importance to end-of-life care. Cardiac patients' perception of their disease's prognosis and the results of cardiopulmonary resuscitation differ greatly from reality. The "do not resuscitate" order allows patients to pre-emptively express their rejection for cardiopulmonary resuscitation, thereby avoiding its potentially negative consequences. However, these orders are still underused and misinterpreted in cardiac patients. Most of these patients usually have no opportunity to have the necessary conversations with their attending physician on their resuscitation preferences. In this review, we performed an analysis of the causes that could explain this situation.

    This study examined whether biases concerning age and/or disability status influenced resuscitation decisions. Medical students were randomly chosen to read 1 of 4 vignettes, organized in a 2 (age: infant vs school-age) × 2 (disability: preexisting vs no preexisting) between-subjects design. The vignettes described a pediatric patient experiencing an acute episode who required resuscitation. Following resuscitation, patients with existing disability would continue to have disability, whereas those without would develop disability. Participants indicated whether they would resuscitate, given a 10% chance of success. There was a significant main effect of disability: Medical students displayed a preference for resuscitating previously disabled children compared with previously healthy children when prognosis was held constant, F(1, 121) = 4.89, p = .03. This differential treatment of the two groups cannot easily be morally justified and poses a quandary for educators.

    Cardiopulmonary arrest is the final result of many diseases and therefore, need for a careful implementation of cardiopulmonary resuscitation (CPR) protocols in these cases is undeniably important. The introduction of ultrasound into the emergency department has potentially allowed the addition of an extra data point in the decision about when to cease cardiopulmonary resuscitation (CPR). The aim of this study is to evaluate the ability of cardiac ultrasonography performed by emergency physicians to predict resuscitation outcome in adult cardiac arrest patients. Ultrasonographic examination of the subxiphoid cardiac area was made immediately after admission to the emergency department with pulseless cardiac arrest. Sonographic cardiac activity was defined as any detectable motion within the heart including the atria, ventricles or valves. Successful resuscitation was defined as: return of spontaneous circulation for ≥ 20 min; return of breathing; palpable pulse; measurable blood pressure. The present study includes 159 patients. The presence of sonographic cardiac activity at the beginning of resuscitation was significantly associated with a successful outcome (41/49 [83.7%] versus 15/110 [13.6%] patients without cardiac activity at the beginning of resuscitation). Ultrasonographic detection of cardiac activity may be useful in determining prognosis during cardiac arrest. Further studies are needed to elucidate the predictive value of ultrasonography in cardiac arrest patients. PMID:27829827

    This publication contains the pediatric and neonatal sections of the 2005 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (COSTR). The consensus process that produced this document was sponsored by the International Liaison Committee on Resuscitation (ILCOR). ILCOR was formed in 1993 and consists of representatives of resuscitation councils from all over the world. Its mission is to identify and review international science and knowledge relevant to cardiopulmonary resuscitation (CPR) and emergency cardiovascular care (ECC) and to generate consensus on treatment recommendations. ECC includes all responses necessary to treat life-threatening cardiovascular and respiratory events. The COSTR document presents international consensus statements on the science of resuscitation. ILCOR member organizations are each publishing resuscitation guidelines that are consistent with the science in this consensus document, but they also take into consideration geographic, economic, and system differences in practice and the regional availability of medical devices and drugs. The American Heart Association (AHA) pediatric and the American Academy of Pediatrics/AHA neonatal sections of the resuscitation guidelines are reprinted in this issue of Pediatrics (see pages e978-e988). The 2005 evidence evaluation process began shortly after publication of the 2000 International Guidelines for CPR and ECC. The process included topic identification, expert topic review, discussion and debate at 6 international meetings, further review, and debate within ILCOR member organizations and ultimate approval by the member organizations, an Editorial Board, and peer reviewers.

    2012-12-01

    Several changes in the way patients with hemorrhagic shock are resuscitated have occurred over the past decades, including permissive hypotension, minimal crystalloid resuscitation, earlier blood transfusion, and higher plasma and platelet-to-red cell ratios. Hemostatic adjuncts, such as tranexamic acid and prothrombin complex, and the use of new methods of assessing coagulopathy are also being incorporated into resuscitation of the bleeding patient. These ideas have been incorporated by many trauma centers into institutional massive transfusion protocols, and adoption of these protocols has resulted in improvements in mortality and morbidity. This article discusses each of these new resuscitation strategies and the evidence supporting their use.

    Objective Assess the relationship between umbilical cord blood magnesium concentration and level of delivery room resuscitation received by neonates. Study design Secondary analysis of a controlled fetal neuroprotection trial that enrolled women at imminent risk for delivery between 24 and 31 weeks’ gestation and randomly allocated them to receive intravenous magnesium sulfate or placebo. The cohort included 1507 infants for whom total cord blood magnesium concentration and delivery room resuscitation information were available. Multivariable logistic regression was used to estimate the association between cord blood magnesium concentration and highest level of delivery room resuscitation, using the following hierarchy: none, oxygen only, bag-mask ventilation with oxygen, intubation or chest compressions. Results There was no relationship between cord blood magnesium and delivery room resuscitation (odds ratio [OR] 0.92 for each 1.0 mEq/L increase in magnesium; 95% confidence interval [CI]: 0.83-1.03). Maternal general anesthesia was associated with increased neonatal resuscitation (OR 2.51; 95% CI: 1.72-3.68). Each 1-week increase in gestational age at birth was associated with decreased neonatal resuscitation (OR 0.63; 95% CI: 0.60 – 0.66). Conclusion Cord blood magnesium concentration does not correlate with the level of delivery room resuscitation of infants exposed to magnesium sulfate for fetal neuroprotection. PMID:22056282

    2014-04-01

    Intraosseous vascular access is a time-tested procedure which has been incorporated into the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation. Intravenous access is often difficult to achieve in shock patients, and central line placement can be time consuming. Intraosseous vascular access, however, can be achieved quickly with minimal disruption of chest compressions. Newer insertion devices are easy to use, making the intraosseous route an attractive alternative for venous access during a resuscitation event. It is critical that anesthesiologists, who are often at the forefront of patient resuscitation, understand how to properly use this potentially life-saving procedure.

    2011-01-01

    The automated external defibrillator (AED), in combination with effective cardiopulmonary resuscitation (CPR), is a critical part of the American Heart Association's "Chain of survival." Newer guidelines have simplified resuscitation and emphasized the importance of CPR in providing rapid and deep compressions with minimal interruptions; in fact, CPR should resume immediately after the shock given by the AED, without the delay entailed in checking for pulse or rhythm conversion. Our experience with the AED aboard aircraft, showing 40% long-term survival with the AED in ventricular fibrillation, demonstrated the safety and efficacy of the device. Despite this and other reports of successful AED deployment, AEDs are not yet available at all public locations. Prospective research, as undertaken by the Resuscitation Outcomes Consortium, will be the key to future refinements of the guidelines and enhanced survival with use of the AED in sudden cardiac arrest.

  17. Resuscitation and DNR: ethical aspects for anaesthetists.

    PubMed

    Layon, A J; Dirk, L

    1995-02-01

    Autonomy is a central ethical principle of medical practice. The physician's autonomy is usually expressed in concert with the other, overriding, ethic of medical care: beneficence. The autonomy of patients, however, has had a growing influence on medical decision-making and can complicate the process. One area where this is especially true is the manner in which cardiopulmonary resuscitation is disallowed: the do-not-resuscitate (DNR) order. Cardiopulmonary resuscitation initially was a therapy automatically instituted in emergencies because it was life-saving. Data began to show, however, that this drastic measure was not always effective. Therefore, its use began to be limited through DNR orders, and policies about DNR orders have been developed to ensure it, in turn, is instituted properly. Besides being used when CPR is futile, the DNR order also serves as a formal means of accounting for a patient's autonomy. Data show, however, that patients are not routinely consulted on this issue even though they want to discuss it. In these cases, quality of life, a patient's subjective evaluation, serves as the basis of a DNR order and makes mandatory communication between physician and patient. Such communication, however, can be obstructed by social values about life and death and the urgent nature of medical care in these situations. To show how such communication ought to be incorporated into medical decision-making, one of the most difficult situations is examined hypothetically: the patient who has a DNR order but who consents to undergo anaesthesia and surgery. In these cases, frequent communication between physician and patient about each therapy and its effect most often will resolve dilemmas.

    Cardiac arrest is associated with a very high rate of mortality, in part due to inadequate tissue perfusion during attempts at resuscitation. Parameters such as mean arterial pressure and end-tidal carbon dioxide may not accurately reflect adequacy of tissue perfusion during cardiac resuscitation. We hypothesised that quantitative measurements of tissue oxygen tension would more accurately reflect adequacy of tissue perfusion during experimental cardiac arrest. Using oxygen-dependent quenching of phosphorescence, we made measurements of oxygen in the microcirculation and in the interstitial space of the brain and muscle in a porcine model of ventricular fibrillation and cardiopulmonary resuscitation. Measurements were performed at baseline, during untreated ventricular fibrillation, during resuscitation and after return of spontaneous circulation. After achieving stable baseline brain tissue oxygen tension, as measured using an Oxyphor G4-based phosphorescent microsensor, ventricular fibrillation resulted in an immediate reduction in all measured parameters. During cardiopulmonary resuscitation, brain oxygen tension remained unchanged. After the return of spontaneous circulation, all measured parameters including brain oxygen tension recovered to baseline levels. Muscle tissue oxygen tension followed a similar trend as the brain, but with slower response times. We conclude that measurements of brain tissue oxygen tension, which more accurately reflect adequacy of tissue perfusion during cardiac arrest and resuscitation, may contribute to the development of new strategies to optimise perfusion during cardiac resuscitation and improve patient outcomes after cardiac arrest.

    Human exposure to high altitude is increasing, through inhabitation of areas of high altitude, expansion of tourism into more remote areas, and air travel exposing passengers to typical altitudes equivalent to 8005 ft (2440 m). With ascent to high altitude, a number of acute and chronic physiological changes occur, influencing all systems of the human body. When considering that cardiac arrest is the second most common cause of death in the mountains and that up to 60% of the elderly have significant heart disease or other health problems, these changes are of particular importance as they may have a significant impact on resuscitation efforts. Current guidelines for resuscitation lack specific recommendations regarding treatment of cardiac arrest after ascent to high altitude or in aircraft. Therefore, we performed a comprehensive search in PubMed, CINAHL, Cochrane Library, and Scopus databases for studies relevant to resuscitation at high altitude. As no randomized trials evaluating the effects of physiological changes after ascent to high altitude on cardiopulmonary resuscitation were identified, our search was expanded to include all studies addressing important aspects on high altitude physiology which could have a potential impact on the resuscitation of cardiac arrest victims. The aim of this review is to discuss the major physiological changes occurring after ascent to high altitude and their potential effects on cardiopulmonary resuscitation. Based on the available data, specific suggestions are proposed regarding resuscitation at high altitude.

    Effective resuscitation requires the integration of several cognitive, technical, and behavioral skills. Because resuscitation is performed by teams of health care professionals, these individuals must be able to work together in a coordinated and efficient manner, making teamwork a critical skill for care of patients in distress. Despite the importance of teamwork in health care, little consensus exists as to what it is, how it can most effectively be learned, and how it should be assessed. This article reviews current knowledge on the measurement, training, and importance of teamwork in pediatric resuscitation.

    2017-01-10

    Extracorporeal cardiopulmonary resuscitation can be used as a rescue strategy in cases of prolonged cardiac arrest caused by massive pulmonary embolism. We present a case of a male patient who was in prolonged cardiac arrest following massive pulmonary embolism. Veno-arterial extracorporeal membrane oxygenation was initiated approximately 93 min after prolonged cardiopulmonary resuscitation. After resuscitation, bedside echocardiography and a chest computed tomography angiogram revealed a massive pulmonary embolism during extracorporeal membrane oxygenation support. The patient received transcatheter mechanical thrombectomy without haemodynamic instability in extracorporeal membrane oxygenation support. He was also treated with therapeutic hypothermia to improve neurological outcome. Renal replacement therapy for acute kidney injury was continued for 36 days. The patient was discharged at 60 days after admission with no serious complications. This case demonstrates that veno-arterial extracorporeal membrane oxygenation and therapeutic hypothermia are an effective treatment strategy for prolonged cardiac arrest caused by massive pulmonary embolism.

    Medical algorithms, technical skills, and repeated training are the classical cornerstones for successful cardiopulmonary resuscitation (CPR). Increasing evidence suggests that human factors, including team interaction, communication, and leadership, also influence the performance of CPR. Guidelines, however, do not yet include these human factors, partly because of the difficulties of their measurement in real-life cardiac arrest. Recently, clinical studies of cardiac arrest scenarios with high-fidelity video-assisted simulations have provided opportunities to better delineate the influence of human factors on resuscitation team performance. This review focuses on evidence from simulator studies that focus on human factors and their influence on the performance of resuscitation teams. Similar to studies in real patients, simulated cardiac arrest scenarios revealed many unnecessary interruptions of CPR as well as significant delays in defibrillation. These studies also showed that human factors play a major role in these shortcomings and that the medical performance depends on the quality of leadership and team-structuring. Moreover, simulated video-taped medical emergencies revealed that a substantial part of information transfer during communication is erroneous. Understanding the impact of human factors on the performance of a complex medical intervention like resuscitation requires detailed, second-by-second, analysis of factors involving the patient, resuscitative equipment such as the defibrillator, and all team members. Thus, high-fidelity simulator studies provide an important research method in this challenging field. PMID:21063563

    The rate of bystander CPR is much lower in China than in developed countries. This survey was implemented to assess the current status of layperson CPR training, to analyze the willingness of bystanders to perform CPR, and to identify barriers to improving bystander CPR rates. The questionnaire included individual information, current status of bystander CPR training, and individual's willingness and attitude towards performing CPR. There were 25.6% laypersons who took CPR training. The majority (98.6%) of laypersons would perform CPR on their family members, but fewer laypersons (76.3%) were willing to perform CPR on strangers. Most respondents (53.2%) were worried about legal issues. If laws were implemented to protect bystanders who give aid, the number of laypersons who were not willing to perform CPR on strangers dropped from 23.7% to 2.4%. An increasing number of people in China know CPR compared with the situation in the past. CPR training in China is much less common than in many developed countries. The barriers are that laypersons are not well-trained and they fear being prosecuted for unsuccessful CPR. More accredited CPR training courses are needed in China. The laws should be passed to protect bystanders who provide assistance. PMID:28367441

    Choking is a common emergency problem. The Heimlich maneuver is unquestionably effective in relieving airway obstruction. Serious and life-threatening complications may arise, however, if the maneuver is applied incorrectly. Two cases of gastric rupture after Heimlich maneuver are reported. Lay public, paramedics and the medical professionals should be educated with the correct technique of Heimlich maneuver and its potential complications. All patients receiving Heimlich maneuver should be examined by an experienced physician.

    Potassium levels are regularly used as a prognostic factor to cease resuscitation in significant hypothermia. In this case report, we highlight how survival is still possible with extreme hyperkalaemia in severe hypothermia. We present a case of a 65-year-old Caucasian man who presented with metformin associated lactic acidosis. On presentation he had potassium of 9.1 mmol/l and a temperature of 31.5 °C. Cardiopulmonary resuscitation was commenced when he went into asystolic arrest. This presentation would commonly make attempts at resuscitation futile with a 100% death rate. However, with appropriate management this patient's condition improved and survival was possible. We provide evidence that survival is possible in profound hyperkalaemia and hypothermia. Effective cardiopulmonary resuscitation with early haemofiltration can be successful.

    Since previous publication in 2005, the most significant changes that have been addressed in the 2010 International Liaison Committee on Resuscitation (ILCOR) recommendations are as follows: (i) use of 2 vital characteristics (heart rate and breathing) to initially evaluate progression to the following step in resuscitation; (ii) oximetry monitoring for the evaluation of oxygenation (assessment of color is unreliable); (iii) for babies born at term it is better to start resuscitation with air rather than 100% oxygen; (iv) administration of supplementary oxygen should be regulated by blending oxygen and air; (v) controversy about endotraqueal suctioning of depressed infants born through meconium-stained amniotic fluid; (vi) chest compression-ventilation ratio should remain at 3/1 for neonates unless the arrest is known to be of cardiac etiology, in which case a higher ratio should be considered; (vii) use of therapeutic hypothermia for infants born at term or near term evolving to moderate or severe hypoxic-ischemic encephalopathy, with protocol and follow-up coordinated through a regional perinatal system (post-resuscitation management); (viii) cord clamping delay for at least 1 minute in babies who do not require resuscitation (there is insufficient evidence to recommend a time for clamping in those who require resuscitation) and, (ix) it is appropriate to consider discontinuing resuscitation if there has been no detectable heart rate for 10 minutes, although many factors contribute to the decision to continue beyond 10 minutes. Under certain circumstances, non-initiation of resuscitation could be proposed taking into consideration general recommendations, own results and parents' opinion.

    Children who require cardiopulmonary resuscitation present high mortality and morbidity. The few studies that have been published on this subject use different terminology and methodology in data collection, which makes comparisons, evaluation of efficacy, and the performance of meta-analyses, etc. difficult. Consequently, standardized data collection both in clinical studies on cardiorespiratory arrest and in cardiopulmonary resuscitation in the pediatric age group are required. The Spanish Group of Pediatric Cardiopulmonary Resuscitation emphasizes that recommendations must be simple and easy to understand. The first step in the elaboration of guidelines on data collection is to develop uniform definitions (glossary of terms). The second step comprises the so-called time intervals that include time periods between two events. To describe the intervals of cardiorespiratory arrest different clocks are used: the patient's watch, that of the ambulance, the interval between call and response, etc.Thirdly, a series of clinical results are gathered to determine whether the efforts of cardiopulmonary resuscitation have a positive effect on the patient, the patient's family and society. With the information gathered a registry of data that includes the patient's personal details, general data of the cardiopulmonary resuscitation, treatment, times of performance and definitive patient outcome is made.

    We utilized a translational model of infant CPB to test the hypothesis that T3 modulates pyruvate entry into the citric acid cycle (CAC) thereby providing the energy support for improved cardiac function after ischemia-reperfusion. Methods and Results: Neonatal piglets received intracoronary [2-13Carbon(13C)]-pyruvate for 40 minutes (8 mM) during control aerobic conditions (Cont) or immediately after reperfusion (IR) from global hypothermic ischemia. A third group (IR-Tr) received T3 (1.2 ug/kg) during reperfusion. We assessed absolute CAC intermediate levels (aCAC) and flux parameters into the CAC through oxidative pyruvate decarboxylation (PDC ) and anaplerotic carboxylation (PC; ) using 13C-labeled pyruvate and isotopomer analysis by gas and liquid chromatography-mass spectrometry and 13C NMR. Neither IR nor IR-Tr modified aCAC. However, compared to IR, T3 (group IR-Tr) increased cardiac power and oxygen consumption after CPB while elevating both PDC and PC (~ four-fold). T3 inhibited IR induced reductions in CAC intermediate molar percent enrichment (MPE) and oxaloacetate(citrate)/malate MPE ratio; an index of aspartate entry into the CAC. Conclusions: T3 markedly enhances PC and PDC thereby providing substrate for elevated cardiac function and work after reperfusion. The increases in pyruvate flux occur with preservation of the CAC intermediate pool. Additionally, T3 inhibition of reductions in CAC intermediate MPEs indicates that T3 reduces the reliance on amino acids (AA) for anaplerosis after reperfusion. Thus, AA should be more available for other functions such as protein synthesis.

    Cardiac arrest remains a leading cause of death and permanent disability worldwide. Although many victims are initially resuscitated, they often succumb to the extensive ischemia-reperfusion injury inflicted on the internal organs, especially the brain. Cardiac arrest initiates a complex cellular injury cascade encompassing reactive oxygen and nitrogen species, Ca2+ overload, ATP depletion, pro- and anti-apoptotic proteins, mitochondrial dysfunction, and neuronal glutamate excitotoxity, which injures and kills cells, compromises function of internal organs and ignites a destructive systemic inflammatory response. The sheer complexity and scope of this cascade challenges the development of experimental models of and effective treatments for cardiac arrest. Many experimental animal preparations have been developed to decipher the mechanisms of damage to vital internal organs following cardiac arrest and cardiopulmonary resuscitation (CPR), and to develop treatments to interrupt the lethal injury cascades. Porcine models of cardiac arrest and resuscitation offer several important advantages over other species, and outcomes in this large animal are readily translated to the clinical setting. This review summarizes porcine cardiac arrest-CPR models reported in the literature, describes clinically relevant phenomena observed during cardiac arrest and resuscitation in pigs, and discusses numerous methodological considerations in modeling cardiac arrest/CPR. Collectively, published reports show the domestic pig to be a suitable large animal model of cardiac arrest which is responsive to CPR, defibrillatory countershocks and medications, and yields extensive information to foster advances in clinical treatment of cardiac arrest.

    2016-01-01

    Hemorrhagic shock is a principal cause of death among trauma patients within the first 24 hours after injury. Optimal fluid resuscitation strategies have been examined for nearly a century, more recently with several randomized controlled trials. Hypotensive resuscitation, also called permissive hypotension, is a resuscitation strategy that uses limited fluids and blood products during the early stages of treatment for hemorrhagic shock. A lower-than-normal blood pressure is maintained until operative control of the bleeding can occur. The randomized controlled trials examining restricted fluid resuscitation have demonstrated that aggressive fluid resuscitation in the prehospital and hospital setting leads to more complications than hypotensive resuscitation, with disparate findings on the survival benefit. Since the populations studied in each randomized controlled trial are slightly different, as is the timing of intervention and targeted vitals, there is still a need for a large, multicenter trial that can examine the benefit of hypotensive resuscitation in both blunt and penetrating trauma patients.

    Singapore has a long way to go to becoming a 'heartsafe' society. Given our small size and culture of hard work in our country, we can achieve a state of good first response by our community citizens through public cardiopulmonary resuscitation and automated external defibrillators training programmes at various key sectors and through the implementation of public access defibrillation in a committed manner. For our second-line responders, investing in technology to improve response times and quality of chest compressions with earlier interventions will go a long way toward strengthening the chain of survival in the community. Building on this strong foundation and having a strong hospital-based cardiac arrest management system will ensure that those who achieve return of spontaneous circulation will more likely remain alive and be discharged from hospital in a neurologically optimal state.

    2017-02-01

    Resuscitation goals for the patient with sepsis and septic shock are to return the patient to a physiologic state that promotes adequate end-organ perfusion along with matching metabolic supply and demand. Ideal resuscitation end points should assess the adequacy of tissue oxygen delivery and oxygen consumption, and be quantifiable and reproducible. Despite years of research, a single resuscitation end point to assess adequacy of resuscitation has yet to be found. Thus, the clinician must rely on multiple end points to assess the patient's overall response to therapy. This review will discuss the role and limitations of central venous pressure (CVP), mean arterial pressure (MAP), and cardiac output/index as macrocirculatory resuscitation targets along with lactate, central venous oxygen saturation (ScvO2), central venous-arterial CO2 gradient, urine output, and capillary refill time as microcirculatory resuscitation endpoints in patients with sepsis.

    Vasoplegia syndrome, characterized by hypotension refractory to fluid resuscitation or high-dose vasopressors, low systemic vascular resistance, and normal-to-increased cardiac index, is associated with increased morbidity and mortality after cardiothoracic surgery. Methylene blue inhibits inducible nitric oxide synthase and guanylyl cyclase, and has been used to treat vasoplegia during cardiopulmonary bypass. However, because methylene blue is associated with increased pulmonary vascular resistance, its use in patients undergoing lung transplantion has been limited. Herein, we report the use of methylene blue to treat refractory vasoplegia during cardiopulmonary bypass in a patient undergoing double-lung transplantation.

    Life sciences research in the cardiopulmonary discipline must identify possible consequences of space flight on the cardiopulmonary system, understand the mechanisms of these effects, and develop effective and operationally practical countermeasures to protect crewmembers inflight and upon return to a gravitational environment. The long-range goal of the NASA Cardiopulmonary Discipline Research Program is to foster research to better understand the acute and long-term cardiovascular and pulmonary adaptation to space and to develop physiological countermeasures to ensure crew health in space and on return to Earth. The purpose of this Discipline Plan is to provide a conceptual strategy for NASA's Life Sciences Division research and development activities in the comprehensive area of cardiopulmonary sciences. It covers the significant research areas critical to NASA's programmatic requirements for the Extended-Duration Orbiter, Space Station Freedom, and exploration mission science activities. These science activities include ground-based and flight; basic, applied, and operational; and animal and human research and development. This document summarizes the current status of the program, outlines available knowledge, establishes goals and objectives, identifies science priorities, and defines critical questions in the subdiscipline areas of both cardiovascular and pulmonary function. It contains a general plan that will be used by both NASA Headquarters Program Offices and the field centers to review and plan basic, applied, and operational (intramural and extramural) research and development activities in this area.

    Drowning is a leading cause of accidental death. Survivors may sustain severe neurologic morbidity. There is negligible research specific to brain injury in drowning making current clinical management non-specific to this disorder. This review represents an evidence-based consensus effort to provide recommendations for management and investigation of the drowning victim. Epidemiology, brain-oriented prehospital and intensive care, therapeutic hypothermia, neuroimaging/monitoring, biomarkers, and neuroresuscitative pharmacology are addressed. When cardiac arrest is present, chest compressions with rescue breathing are recommended due to the asphyxial insult. In the comatose patient with restoration of spontaneous circulation, hypoxemia and hyperoxemia should be avoided, hyperthermia treated, and induced hypothermia (32–34 °C) considered. Arterial hypotension/hypertension should be recognized and treated. Prevent hypoglycemia and treat hyperglycemia. Treat clinical seizures and consider treating non-convulsive status epilepticus. Serial neurologic examinations should be provided. Brain imaging and serial biomarker measurement may aid prognostication. Continuous electroencephalography and N20 somatosensory evoked potential monitoring may be considered. Serial biomarker measurement (e.g., neuron specific enolase) may aid prognostication. There is insufficient evidence to recommend use of any specific brain-oriented neuroresuscitative pharmacologic therapy other than that required to restore and maintain normal physiology. Following initial stabilization, victims should be transferred to centers with expertise in age-specific post-resuscitation neurocritical care. Care should be documented, reviewed, and quality improvement assessment performed. Preclinical research should focus on models of asphyxial cardiac arrest. Clinical research should focus on improved cardiopulmonary resuscitation, re-oxygenation/reperfusion strategies, therapeutic hypothermia

    First year pupils at a Cardiff comprehensive school were trained in cardiopulmonary resuscitation, 106 by the teacher only and 137 by the teacher assisted by older pupils (peer tutoring). Scores in a multiple choice theory test and in practical skill assessment showed no significant difference between instruction methods, but boys taught by the teacher assisted by older pupils expressed less willingness to resuscitate in an emergency than girls instructed by either method (P < 0.01). Girls had higher scores in the multiple choice paper (P < 0.025) and in the skills assessment (P < 0.01). Those pupils who reported some prior knowledge of resuscitation techniques performed better during skill assessment than novice trainees (P < 0.025).

    2009-12-01

    It is widely believed in neonatology and obstetrics that there are situations in which it is inappropriate to attempt newborn resuscitation, and other times when newborn resuscitation is obligatory despite parental refusal. In each case, an ethical justification for the decision needs to be identified. This essay is intended to provide guidance in deciding when resuscitation should be attempted, and in identifying ethical considerations that should be taken into account. It specifically addresses the issue of extreme prematurity, including an analysis of current recommendations, the data, relevant rights of patient and parents, and a discussion of the relative merits of withholding resuscitation vs providing resuscitation and possibly withdrawing intensive care later. In addition to extreme prematurity, the considerations presented are also relevant to a wider spectrum of newborn problems, including Trisomy 13, Trisomy 18, and severe congenital anomalies.

    2016-01-01

    Do-not-resuscitate (DNR) orders are necessary if resuscitation, the default option in hospitals, should be avoided because a patient is known to be dying and attempted resuscitation would be inappropriate. To avoid inappropriate resuscitation at night, if no DNR order has been recorded, after-hours medical staff are often asked to have a DNR discussion with patients whose condition is deteriorating, but with whom they are unfamiliar. Participants in two qualitative studies of cancer patients’ views on how to present DNR discussions recognized that such patients are at different stages of understanding of their situation and may not be ready for a DNR discussion; therefore, a one-policy-fits-all approach was thought to be inappropriate. To formulate a policy that incorporates the patient’s views, we propose that a standard form which mandates a DNR discussion is replaced by a “blank sheet” with instructions to record the progress of the discussion with the patient, and a medical recommendation for a DNR decision to guide the nursing staff in case of a cardiac arrest. Such an advance care directive would have to honor specifically expressed patient or guardian wishes whilst allowing for flexibility, yet would direct nurses or other staff so that they can avoid inappropriate cardiopulmonary resuscitation of a patient dying of cancer.

    Improving teamwork in healthcare may help reduce and manage errors. This paper takes a step toward that goal by (1) proposing a set of teamwork behaviours, or behavioural markers, for neonatal resuscitation; (2) presenting a data form for recording observations about these markers; and (3) comparing and contrasting different sets of teamwork behaviours that have been developed for healthcare. Data from focus groups of neonatal providers, surveys, and video recordings of neonatal resuscitations were used to identify some new teamwork behaviours, to translate existing aviation team behaviours to this setting, and to develop a data collection form. This behavioural marker audit form for neonatal resuscitation lists and defines 10 markers that describe specific, observable behaviours seen during the resuscitation of newborn infants. These markers are compared with those developed by other groups. Future research should determine the relations among these behaviours and errors, and test their usefulness in measuring the impact of team training interventions.

    Cardiac arrest induces whole-body ischemia, which causes damage to multiple organs. Understanding how each organ responds to ischemia/reperfusion is important to develop better resuscitation strategies. Because direct measurement of organ function is not practicable in most animal models, we attempt to use mitochondrial respiration to test efficacy of resuscitation on the brain, heart, kidney, and liver following prolonged cardiac arrest. Male Sprague-Dawley rats are subjected to asphyxia-induced cardiac arrest for 30 min or 45 min, or 30 min cardiac arrest followed by 60 min cardiopulmonary bypass resuscitation. Mitochondria are isolated from brain, heart, kidney, and liver tissues and examined for respiration activity. Following cardiac arrest, a time-dependent decrease in state-3 respiration is observed in mitochondria from all four tissues. Following 60 min resuscitation, the respiration activity of brain mitochondria varies greatly in different animals. The activity after resuscitation remains the same in heart mitochondria and significantly increases in kidney and liver mitochondria. The result shows that inhibition of state-3 respiration is a good marker to evaluate the efficacy of resuscitation for each organ. The resulting state-3 respiration of brain and heart mitochondria following resuscitation reenforces the need for developing better strategies to resuscitate these critical organs following prolonged cardiac arrest.

    2011-01-01

    Abstract Intensive cardiopulmonary management is frequently undertaken in patients with spinal cord injury (SCI), particularly due to the occurrence of neurogenic shock and ventilatory insufficiency and in an attempt to reduce secondary injury. We undertook a systematic review of the literature to examine the evidence that intensive care management improves outcome after SCI and to attempt to define key parameters for cardiopulmonary support/resuscitation. We review the literature in five areas: management of SCI patients in specialized centers, risk in SCI patients of cardiopulmonary complications, parameters for blood pressure and oxygenation/ventilation support following SCI, risk factors for cardiopulmonary insufficiency requiring ICU care after SCI, and preventative strategies to reduce the risks of cardiopulmonary complications in SCI patients. The literature supports that, in light of the significant incidence of cardiorespiratory complications, SCI patients should be managed in a monitored special care unit. There is weak evidence supporting the maintenance of MAP >85 mmHg for a period extending up to 1 week following SCI. PMID:20030558

    Due to familiarity, short half-life, ease of monitoring, and the availability of a reversal agent, heparin remains the anticoagulant of choice for cardiac operations requiring cardiopulmonary bypass (CPB). However, occasionally patients require CPB but should not receive heparin, most often because of acute or subacute heparin-induced thrombocytopenia (HIT). In these cases, if it is not feasible to wait for the disappearance of HIT antibodies, an alternative anticoagulant must be selected. A number of non-heparin anticoagulant options have been explored. However, current recommendations suggest the use of a direct thrombin inhibitor such as bivalirudin. This review describes the use of heparin alternatives for the conduct of CPB with a focus on the direct thrombin inhibitors.

    Coronary artery spasm can lead to sudden cardiac death due to ventricular arrhythmias or heart block. Cardiopulmonary resuscitation guidelines recommend the use of epinephrine during cardiopulmonary arrest. However, in the event of cardiac arrest caused by coronary artery spasm, the use of epinephrine may be harmful. We report 2 cases who had witnessed cardiac arrest due to ventricular fibrillation and complete heart block. Intravenous epinephrine was administered during resuscitation.Their hemodynamics did not improve. Emergent coronary angiography revealed that the entire right and left coronary artery systems diffuse spasm. One patient's coronary artery spasm was successfully reversed immediately with administration of intracoronary boluses of nitroglycerin. The other patient's hemodynamic instability persisted,requiring temporary mechanical circulatory support with an intra aortic balloon pump. His hemodynamics finally improved with administration of intravenous diltiazem and nitroglycerin under the intraaortic balloon pump support. They both were discharged from the hospital without any other complications.

  9. Indications for Cardiopulmonary Bypass During Pregnancy and Impact on Fetal Outcomes

    Yuan, S.-M.

    2014-01-01

    Background: Cardiac operations in pregnant patients are a challenge for physicians in multidisciplinary teams due to the complexity of the condition which affects both mother and baby. Management strategies vary on a case-by-case basis. Feto-neonatal and maternal outcomes after cardiopulmonary bypass (CPB) in pregnancy, especially long-term follow-up results, have not been sufficiently described. Methods: This review was based on a complete literature retrieval of articles published between 1991 and April 30, 2013. Results: Indications for CPB during pregnancy were cardiac surgery in 150 (96.8 %) patients, most of which consisted of valve replacements for mitral and/or aortic valve disorders, resuscitation due to amniotic fluid embolism, autotransfusion, and circulatory support during cesarean section to improve patient survival in 5 (3.2 %) patients. During CPB, fetuses showed either a brief heart rate drop with natural recovery after surgery or, in most cases, fetal heart rate remained normal throughout the whole course of CPB. Overall feto-neonatal mortality was 18.6 %. In comparison with pregnant patients whose baby survived, feto-neonatal death occurred after a significantly shorter gestational period at the time of onset of cardiac symptoms, cardiac surgery/resuscitation under CPB in the whole patient setting, or cardiac surgery/resuscitation with CPB prior to delivery. Conclusions: The most common surgical indications for CPB during pregnancy were cardiac surgery, followed by resuscitation for cardiopulmonary collapse. CPB was used most frequently in maternal cardiac surgery/resuscitation in the second trimester. Improved CPB conditions including high flow, high pressure and normothermia or mild hypothermia during pregnancy have benefited maternal and feto-neonatal outcomes. A shorter gestational period and the use of CPB during pregnancy were closely associated with feto-neonatal mortality. It is therefore important to attempt delivery ahead of

    INTRODUCTION Out-of-hospital cardiopulmonary arrest (CPA) in children is rare but significant, with poor survival rates and high morbidity. Asystole is the most common dysrhythmia, and cardiopulmonary resuscitation (CPR) is of great importance in such cases. We aimed to survey the knowledge, attitudes and perceptions of parents in Singapore regarding infant basic life support (IBLS). METHODS A questionnaire survey was administered to parents of children managed at the Neonatal Department of Singapore General Hospital, Singapore, between 1 September and 31 December 2008. The questionnaire consisted of three sections – section A collected demographic data, section B included questions on knowledge, and section C explored attitudes and perceptions. Knowledge T-scores were analysed for the entire cohort and subanalysed with respect to prior IBLS training. RESULTS In our study cohort (n = 375), the median Basic Knowledge (BK) T-score was 7 (range 1–9) and the pass rate was 55%. Median BK T-scores were significantly different between untrained (6; range 3 –9) and previously trained (8; range 3–9) participants. A majority of the trained participants obtained pass marks. Median Total Knowledge T-score, involving advanced questions, for previously trained participants was 11 (range 3–14), but pass rate was low (35.7%). Higher educational qualification was a significant factor impacting all scores. Untrained participants indicated interest in attending IBLS courses, while trained participants were interested in refresher courses. CONCLUSION IBLS training, as part of basic cardiac life support training, is important given that CPR can significantly alter the outcome in children with CPA. Our survey revealed knowledge gaps that could be bridged through formal training. Refresher courses to regularly update parents’ knowledge are recommended. PMID:24664380

    Occipitally joined craniopagus Siamese twins were separated with the use of cardiopulmonary bypass and hypothermic circulatory arrest. The 7-month-old infants shared a large sagittal venous sinus that precluded conventional neurosurgical approach because of risk of exsanguination and air embolism. After craniotomy and preliminary exposure of the sinus, each twin underwent sternotomy and total cardiopulmonary bypass with deep hypothermia. Hypothermic circulatory arrest allowed safe division and subsequent reconstruction of the sinus remnants. Several unusual problems were encountered, including transfusion of a large blood volume from one extracorporeal circuit to the other through the common venous sinus, deleterious warming of the exposed brain during circulatory arrest, and thrombosis of both pump oxygenators. Both infants survived, although recovery was complicated in each by neurologic injury, cranial wound infection, and hydrocephalus. This case demonstrates the valuable supportive role of cardiopulmonary bypass and hypothermic circulatory arrest in the management of complex surgical problems of otherwise inoperable patients.

Recent studies demonstrated that hydrogen sulfide (H2S) donor compounds preserve mitochondrial morphology and function during ischemia-reperfusion injury. In this study, we sought to explore the effects of sodium hydrosulfide (NaHS) on brain mitochondria 24h after cardiac arrest and resuscitation. Male Sprague-Dawley rats were subjected to 6min cardiac arrest and then resuscitated successfully. Rats received NaHS (0.5mg/kg) or vehicle (0.9% NaCl, 1.67ml/kg) 1min before the start of CPR intravenously, followed by a continuous infusion of NaHS (1.5mg/kg/h) or vehicle (5ml/kg/h) for 3h. Neurological deficit was evaluated 24h after resuscitation and then cortex was collected for assessments. As a result, we found that rats treated with NaHS revealed an improved neurological outcome and cortex mitochondrial morphology 24h after resuscitation. We also observed that NaHS therapy reduced intracellular reactive oxygen species generation and calcium overload, inhibited mitochondrial permeability transition pores, preserved mitochondrial membrane potential, elevated ATP level and ameliorated the cytochrome c abnormal distribution. Further studies indicated that NaHS administration increased mitochondrial biogenesis in cortex at the same time. Our findings suggested that administration of NaHS 1min prior CPR and followed by a continuous infusion ameliorated neurological dysfunction 24h after resuscitation, possibly through mitochondria preservation as well as by promoting mitochondrial biogenesis.

    This paper introduces adult basic life support (BLS) guidelines for lay rescuers of the resuscitation council of Asia (RCA) developed for the first time. The RCA BLS guidelines for lay rescuers have been established by expert consensus among BLS Guidelines Taskforce of the RCA on the basis of the 2015 International Consensus on Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care Science with Treatment Recommendations. The RCA recommends compression-only CPR for lay rescuers and emphasizes high-quality CPR with chest compression depth of approximately 5cm and chest compression rate of 100-120min(-1). Role of emergency medical dispatchers in helping lay rescuers recognize cardiac arrest and perform CPR is also emphasized. The RCA guidelines will contribute to help Asian countries establish and implement their own CPR guidelines in the context of their domestic circumstances.

  16. The Ethical and Legal Framework for the Decision Not to Resuscitate

    Practicing physicians are frequently faced with the question of whether or not to institute cardiopulmonary resuscitation in case of cardiac or respiratory arrest in a patient in hospital. Medical training has usually not included any systematic analysis of this issue from either an ethical or a legal standpoint. Many physicians may be unaware that ethical and legal principles, as well as professional guidelines, exist to guide such decision making. In practice, physicians make this decision without the benefit of training in ethical analysis. The problem is especially acute in teaching hospitals when young physicians unacquainted with formal ethics or the law must often make decisions emergently. Studies show some discrepancy between ethical and legal principles and the actual decision making by physicians. For this reason, we recommend an approach that will enable physicians to make and implement decisions not to resuscitate that are consistent with current ethical and legal standards. PMID:6702189

    The lung is profoundly affected by gravity. The absence of gravity (microgravity) removes the mechanical stresses acting on the lung paranchyma itself, resulting in a reduction in the deformation of the lung due to its own weight, and consequently altering the distribution of fresh gas ventilation within the lung. There are also changes in the mechanical forces acting on the rib cage and abdomen, which alters the manner in which the lung expands. The other way in which microgravity affects the lung is through the removal of the gravitationally induced hydrostatic gradients in vascular pressures, both within the lung itself, and within the entire body. The abolition of a pressure gradient within the pulmonary circulation would be expected to result in a greater degree of uniformity of blood flow within the lung, while the removal of the hydrostatic gradient within the body should result in an increase in venous return and intra-thoracic blood volume, with attendant changes in cardiac output, stroke volume, and pulmonary diffusing capacity. During the 9 day flight of Spacelab Life Sciences-1 (SLS-1) we collected pulmonary function test data on the crew of the mission. We compared the results obtained in microgravity with those obtained on the ground in both the standing and supine positions, preflight and in the week immediately following the mission. A number of the tests in the package were aimed at studying the anticipated changes in cardiopulmonary function, and we report those in this communication.

    Cardiopulmonary resuscitation (CPR) is relatively novel branch of medical science, however first descriptions of mouth-to-mouth ventilation are to be found in the Bible and literature is full of descriptions of different resuscitation methods - from flagellation and ventilation with bellows through hanging the victims upside down and compressing the chest in order to stimulate ventilation to rectal fumigation with tobacco smoke. The modern history of CPR starts with Kouwenhoven et al. who in 1960 published a paper regarding heart massage through chest compressions. Shortly after that in 1961Peter Safar presented a paradigm promoting opening the airway, performing rescue breaths and chest compressions. First CPR guidelines were published in 1966. Since that time guidelines were modified and improved numerously by two leading world expert organizations ERC (European Resuscitation Council) and AHA (American Heart Association) and published in a new version every 5 years. Currently 2010 guidelines should be obliged. In this paper authors made an attempt to present history of development of resuscitation techniques and methods and assess the influence of previous lifesaving methods on nowadays technologies, equipment and guidelines which allow to help those women and men whose life is in danger due to sudden cardiac arrest.

    Each year in the US, some four hundred thousand newborns need help breathing when they are born. Due to the frequent need for resuscitation at birth, it is vital to have evidence-based care guidelines and to provide effective neonatal resuscitation training. Every five years, the International Liaison Committee on Resuscitation (ILCOR) reviews the science of neonatal resuscitation. In the US, the American Heart Association (AHA) develops treatment guidelines based on the ILCOR science review, and the Neonatal Resuscitation Program (NRP) translates the AHA guidelines into an educational curriculum. In this report, we review recent advances in neonatal resuscitation training and practice. We begin with a review of the new 7th edition NRP training curriculum. Then, we examine key changes to the 2015 AHA neonatal resuscitation guidelines. The four components of the NRP curriculum reviewed here include eSim®, Performance Skills Stations, Integrated Skills Station, and Simulation and Debriefing. The key changes to the AHA neonatal resuscitation guidelines reviewed include initial steps of newborn care, positive-pressure ventilation, endotracheal intubation and use of laryngeal mask, chest compressions, medications, resuscitation of preterm newborns, and ethics and end-of-life care. We hope this report provides a succinct review of recent advances in neonatal resuscitation. PMID:28096704

    We retrospectively evaluated early outcome and conducted this study to determine the predictive factors for percutaneous cardiopulmonary support (PCPS) weaning and hospital discharge. From January 2004 to December 2006, 92 patients diagnosed as cardiac or respiratory failure underwent PCPS using the Capiox emergent bypass system (Terumo, Tokyo, Japan). The mean+/-S.D. age was 56+/-18 (range, 14-85) years and 59 (64%) were male. The mean duration of PCPS was 90.9+/-126.0 h and that of cardiopulmonary resuscitation (CPR) was 51.1+/-27.8 min. The rate of weaning was 59/92 (64%) and the rate of survival to discharge was 39/92 (42%). The results indicated that the etiologic disease (myocarditis) and the cause of PCPS (cardiopulmonary arrest) are significantly correlated with weaning, whereas cardiopulmonary arrest and a shorter CPR duration (<60 min) are considerably correlated with survival. On the contrary, elderly patients (>75 years) have similar rates of weaning and survival compared with younger patients. PCPS provides an acceptable survival rate and outcome in patients with cardiac or respiratory failure. Prompt application and selection of patients with a specific disease (myocarditis) provides good results. It is also effective in elderly patients, providing hospital survival similar to that for younger patients.

    This study aims to compare the Jostra HL-20 roller pump to the Medos DeltaStream DP1 rotary pump in terms of pressure and flow waveforms, as well as calculated energies based on pressure/flow relationships, in a simulated pediatric cardiopulmonary perfusion system. The flow rate was set at 1,000 ml/min for each pump, under both pulsatile and nonpulsatile perfusion modes. Mean arterial pressure (MAP) was maintained at 40 mm Hg. Pressure and flow measurements and waveforms were recorded at precannula site in the bypass circuit. Blood analog test fluid was used to simulate blood properties. A total of 24 experiments were performed (n = 12 nonpulsatile and n = 12 pulsatile). A significant increase in surplus hemodynamic energy (SHE) was observed in both pumps under pulsatile perfusion. In contrast, nonpulsatile perfusion generated very little SHE in the Jostra roller pump, whereas no SHE was generated in the Medos rotary pump. However, under pulsatile perfusion, the Medos rotary pump generated more than twice the amount of SHE or "extra" energy than the Jostra roller pump. The total hemodynamic energy was also significantly higher in the Medos rotary pump than the Jostra roller pump, under pulsatile perfusion. This pilot study suggests that the Medos DeltaStream DP1 rotary pump may produce greater hemodynamic energy levels and higher quality physiologic pressure/flow waveforms than the Jostra roller pump. Further investigation of the Medos DeltaStream DP1 rotary pump is necessary to evaluate hemodynamic energy generation under various pump settings, in contrast to different flow rates.

    This study evaluated the interrater reliability and perceived importance of components of a developed neonatal adaption score, Neonatal Resuscitation Adaptation Score (NRAS), for evaluation of resuscitation need in the delivery room for extremely premature to term infants. Similar to the Apgar, the NRAS highest score was 10, but greater weight was given to respiratory and cardiovascular parameters. Evaluation of provider (N = 17) perception and scoring pattern was recorded for 5 clinical scenarios of gestational ages 23 to 40 weeks at 1 and 5 minutes and documenting NRAS and Apgar score. Providers assessed the tool twice within a 1-month interval. NRAS showed superior interrater reliability (P < .001) and respiratory component reliability (P < .001) for all gestational ages compared to the Apgar score. These findings identify an objective tool in resuscitation assessment of infants, especially those of smaller gestation age, allowing for greater discrimination of postbirth transition in the delivery room.

    Abstract Patients with multiple traumas associated with cardiopulmonary failure have a high mortality rate; however, such patients can be temporarily stabilized using extracorporeal membrane oxygenation (ECMO), providing a bridge to rescue therapy. Using a retrospective study design, we aimed to clarify the prognostic factors of post-traumatic ECMO support. From March 2006 to July 2016, 43 adult patients (mean age, 37.3 ± 15.2 years; 7 females [16.3%]) underwent ECMO because of post-traumatic cardiopulmonary failure. Pre-ECMO demographics, peri-ECMO events, and post-ECMO recoveries were compared between survivors and nonsurvivors. The most common traumatic insult was traffic collision (n = 30, 69.8%), and involved injury areas included the chest (n = 33, 76.7%), head (n = 14, 32.6%), abdomen (n = 21, 48.8%), and fractures (n = 21, 48.8%). Fifteen patients (34.9%) underwent cardiopulmonary resuscitation and 22 (51.2%) received rescue interventions before ECMO deployment. The mean time interval between trauma and ECMO was 90.6 ± 130.1 hours, and the mode of support was venovenous in 26 patients (60.5%). A total of 26 patients (60.5%) were weaned off of ECMO and 22 (51.6%) survived to discharge, with an overall mean support time of 162.9 ± 182.7 hours. A multivariate regression analysis identified 2 significant predictors for in-hospital mortality: an injury severity score (ISS) >30 (odds ratio [OR], 9.48; 95% confidence interval [CI], 1.04–18.47; P = 0.042), and the requirement of renal replacement therapy (RRT) during ECMO (OR, 8.64; 95% CI, 1.73–26.09; P = 0.020). These two factors were also significant for the 1-year survival (ISS >30: 12.5%; ISS ≤30, 48.1%, P = 0.001) (RRT required, 15.0%; RRT not required, 52.2%, P = 0.006). Using ECMO in selected traumatized patients with cardiopulmonary failure can be a salvage therapy. Prompt intervention before shock-impaired systemic organ perfusion and acute

    Background End-tidal CO2 (ETCO2), partial pressure of exhaled CO2 (PECO2), and volume of expired CO2 (VCO2) can be continuously monitored non-invasively to reflect pulmonary ventilation and perfusion status. Although ETCO2 ≥14mmHg has been shown to be associated with return of an adequate heart rate in neonatal resuscitation and quantifying the PECO2 has the potential to serve as an indicator of resuscitation quality, there is little information regarding capnometric measurement of PECO2 and ETCO2 in detecting return of spontaneous circulation (ROSC) and survivability in asphyxiated neonates receiving cardiopulmonary resuscitation (CPR). Methods Seventeen newborn piglets were anesthetized, intubated, instrumented, and exposed to 45-minute normocapnic hypoxia followed by apnea to induce asphyxia. Protocolized resuscitation was initiated when heart rate decreased to 25% of baseline. Respiratory and hemodynamic parameters including ETCO2, PECO2, VCO2, heart rate, cardiac output, and carotid artery flow were continuously measured and analyzed. Results There were no differences in respiratory and hemodynamic parameters between surviving and non-surviving piglets prior to CPR. Surviving piglets had significantly higher ETCO2, PECO2, VCO2, cardiac index, and carotid artery flow values during CPR compared to non-surviving piglets. Conclusion Surviving piglets had significantly better respiratory and hemodynamic parameters during resuscitation compared to non-surviving piglets. In addition to optimizing resuscitation efforts, capnometry can assist by predicting outcomes of newborns requiring chest compressions. PMID:26766424

    One approach to reducing avoidable mortality from coronary artery disease is to provide resuscitation capability in the community. In Manitoba this is the function of the Heart-Alert program, sponsored by the Manitoba Heart Foundation. The program is based on public and professional education dealing with the recognition and immediate care of cardiac emergencies, including cardiopulmonary resuscitation (CPR). The three components to the program are (a) training in basic CPR for all health care and community rescue groups; (b) training in definitive CPR for physicians, critical care nurses and advanced emergency medical technicians; and (c) education of the public to recognize the signs of impending or actual cardiac emergencies and to take appropriate action to summon quickly an emergency rescue team. The initial emphasis of the program has been on developing an organizational structure and a training network for basic CPR. A corps of instructor-trainers and instructors has been certified to implement CPR training in the medical and community target groups. Developmental problems include problems of quality control, of providing for self-sustaining and continued expansion, and of evaluation of the overall results. It is suggested that widespread implementation of CPR training is facilitated by the incorporation of CPR into existing training activities, particularly those of the medical, nursing and other health care disciplines, those of community protection agencies such as police, fire and ambulance departments, and those of volunteer groups concerned with rescue work and first-aid. If the impetus, organizational structure and instructor training are provided by a strategic agency, wide dissemination of CPR training is then possible at relatively modest cost. PMID:589540

    Multiply injured patients represent a particularly demanding subgroup of trauma patients as they require urgent simultaneous clinical assessments using physical examination, ultrasound and invasive monitoring together with critical management, including tracheal intubation, thoracostomies and central venous access. Concurrent access to multiple body regions is essential to facilitate the concept of 'horizontal' resuscitation. The current positioning of trauma patient, with arms adducted, restricts this approach. Instead, the therapeutic cruciform positioning, with arms abducted at 90°, allows planning and performing of multiple life-saving interventions simultaneously. This positioning also provides a practical surgical field with improved sterility and procedural access.

    Extracorporeal cardiopulmonary support (ECS) of donors after cardiac death (DCD) has been shown to improve abdominal organs for transplantation. This study assesses whether pulmonary congestion occurs during ECS with the heart arrested and describes an in vivo method to assess if lungs are suitable for transplantation from DCD donors after ECS resuscitation. Cardiac arrest was induced in 30 kg pigs, followed by 10 min of warm ischemia. Cannulae were placed into the right atrium (RA) and iliac artery, and veno-arterial ECS was initiated for 90 min with lungs inflated, group 1 (n = 5) or deflated, group 2 (n = 3). Left atrial pressures were measured as a marker for pulmonary congestion. After 90 min of ECS, lung function was evaluated. Cannulae were placed into the pulmonary artery (PA) and left ventricle (LV). A second pump was included, and ECS was converted to a bi-ventricular (bi-VAD) system. The RVAD drained from the RA and pumped into the PA, and the LVAD drained the LV and pumped into the iliac. This brought the lungs back into circulation for a 1-hr assessment period. The oxygenator was turned off, and ventilation was restarted. Flows, blood gases, PA and left atrial pressures, and compliance were recorded. In both the groups, LA pressure was <15 mm Hg during ECS. During the lung assessment period, PA flows were 1.4-2.2 L/min. PO2 was >300 mm Hg, with normal PCO2. Extracorporeal cardiopulmonary support resuscitation of DCD donors is feasible and allows for assessment of function before procurement. Extracorporeal cardiopulmonary support does not cause pulmonary congestion, and the lungs retain adequate function for transplantation. Compliance correlated with lung function.

    There is strong evidence to suggest that angiotensin-converting enzyme inhibitors (ACEIs) protect against local myocardial ischemia/reperfusion (I/R) injury. This study was designed to explore whether ACEIs exert cardioprotective effects in a swine model of cardiac arrest (CA) and resuscitation. Male pigs were randomly assigned to three groups: sham-operated group, saline treatment group and enalapril treatment group. Thirty minutes after drug infusion, the animals in the saline and enalapril groups were subjected to ventricular fibrillation (8 min) followed by cardiopulmonary resuscitation (up to 30 min). Cardiac function was monitored, and myocardial tissue and blood were collected for analysis. Enalapril pre-treatment did not improve cardiac function or the 6-h survival rate after CA and resuscitation; however, this intervention ameliorated myocardial ultrastructural damage, reduced the level of plasma cardiac troponin I and decreased myocardial apoptosis. Plasma angiotensin (Ang) II and Ang-(1–7) levels were enhanced in the model of CA and resuscitation. Enalapril reduced the plasma Ang II level at 4 and 6 h after the return of spontaneous circulation whereas enalapril did not affect the plasma Ang-(1–7) level. Enalapril pre-treatment decreased the myocardial mRNA and protein expression of angiotensin-converting enzyme (ACE). Enalapril treatment also reduced the myocardial ACE/ACE2 ratio, both at the mRNA and the protein level. Enalapril pre-treatment did not affect the upregulation of ACE2, Ang II type 1 receptor (AT1R) and MAS after CA and resuscitation. Taken together, these findings suggest that enalapril protects against ischemic injury through the attenuation of the ACE/Ang II/AT1R axis after CA and resuscitation in pigs. These results suggest the potential therapeutic value of ACEIs in patients with CA. PMID:27633002

    Sepsis results in widespread inflammatory responses altering homeostasis. Associated circulatory abnormalities (peripheral vasodilation, intravascular volume depletion, increased cellular metabolism, and myocardial depression) lead to an imbalance between oxygen delivery and demand, triggering end organ injury and failure. Fluid resuscitation is a key part of treatment, but there is little agreement on choice, amount, and end points for fluid resuscitation. Over the past few years, the safety of some fluid preparations has been questioned. Our paper highlights current concerns, reviews the science behind current practices, and aims to clarify some of the controversies surrounding fluid resuscitation in sepsis. PMID:25180196

    Our results may be briefly summarized: 1. Blood, when defibrinated, soon loses its power to maintain the activity of the higher nervous centers, and its nutritive properties for all tissues quickly diminish. 2. Artificial fluids, as a substitute for blood, are not satisfactory. 3. The proper oxygenation of the blood is an indispensable adjunct in the resuscitation of an animal. 4. The heart usually continues to beat for some minutes after it ceases to affect a mercury manometer, and resuscitation of it within this period by extra-thoracic massage and artificial respiration is sometimes successful. 5. Resuscitation of the heart by direct massage is the most certain method at our command. 6. A proper blood-pressure is an indispensable condition for the continued normal activity of the heart. 7. Anæsthetics, hemorrhage and induced currents applied to the heart render resuscitation more difficult than asphyxia alone. PMID:19867138

    The development of cardiopulmonary bypass (CPB), thereby permitting open-heart surgery, is one of the most important advances in medicine in the 20th century. Many currently practicing cardiac anesthesiologists, cardiac surgeons, and perfusionists are unaware of how recently it came into use (60 years) and how much the practice of CPB has changed during its short existence. In this paper, the development of CPB and the many changes and progress that has taken place over this brief period of time, making it a remarkably safe endeavor, are reviewed. The many as yet unresolved questions are also identified, which sets the stage for the other papers in this issue of this journal.

    The objective of this study was to develop an educational software program for nursing continuing education. This program was intended to incorporate applied methodological research that used the learning management system methodology created by Galvis Panqueva in association with contextualized instructional design for software design. As a result of this study, we created a computerized educational product (CEP) called ENFNET. This study describes all the necessary steps taken during its development. The creation of a CEP demands a great deal of study, dedication and investment as well as the necessity of specialized technical personnel to construct it. At the end of the study, the software was positively evaluated and shown to be a useful strategy to help users in their education, skills development and professional training.

    Background To assess the level of knowledge of CPR among House-Officers (HO) and some factors determining accuracy of knowledge. Methods A total of 50 structured questionnaires were administered to HO with 35 (70%) questionnaires duly filled and returned. Data on the participants’ brief biodata and the understanding of basic skills of BLS were collected and analyzed using International Business Machine SPSS Statistics version 21 for Windows. The t-test for independent samples was applied for the grouped data with P < 0.05 taken as level of significance. Results The age of the respondents ranged from 20-37 years with the mean age of 25.4 + SD2.7 years and the male/female ratio was 1:1.3. Eleven (31.4%) out of the 35 HO had no prior CPR training while 68.6% had prior training; Eighteen (51.4%) had training within the last 2 years. Twenty (57.1%) had performed CPR in a real situation, while 42.9% had not. Six (17.1%) HO scored above 50% while 82.9% scored below 50%. The female HO got more correct answers than the males (25% versus 6.7%, p = 0.167). The number of respondents who had prior CPR training had more correct answers than those who did not (25% versus 0%, p = 0.083) while those who had previously performed CPR had more correct answers than those who had not (33.3% versus 5%, P <0.05). Conclusion There was a general poor knowledge of the performance of basic CPR amongst HOs. However, previous experience of having performed CPR in real setting, or the use of mannequins, improved their theoretical knowledge of CPR. PMID:25419335

    Records of cardiac arrest are not usually made, or are incomplete, and should contain more information. This study aimed at applying a tool developed to record in-hospital cardiac arrest. The tool was previously validated by experts, and then applied by registered nurses in six wards. Fifty-four cases of in-hospital cardiac arrest were recorded, and over 90% positive answers, relative to evaluation criteria, were obtained. In the analysis of entry per data set, the average was higher than 70%. It was concluded that the tool supplied the needs of cardiac arrest recording for this hospital.

    Objective: To examine how commonly barriers to telephone CPR occur and whether this affects the time it takes to perform the intervention. Method: A retrospective quantitative analysis was undertaken using a convenience sample of 100 emergency calls. Calls were identified in the emergency control room as cardiac arrests and confirmed by the responding paramedics as cardiac arrests. The calls were listened to, established if CPR instructions were given, if the instructions were followed, if anything hindered the instructions undertaken, and the time taken to reach key points. Findings: 18 cases had bystander CPR administered. An additional 56 of cases had CPR instructions provided but "barriers" in 49% (n = 27) hindered the effectiveness of these. The median time to recognition of cardiac arrest was 40 seconds, with time to first ventilation being 4 min 10 s and time to first compression 5 min 30 s. These times were notably higher in those cases where a barrier to effective telephone CPR existed. Conclusions: Barriers to undertaking telephone CPR occurred with a high degree of frequency. These barriers affect the ability of the caller to perform rapid and effective telephone CPR. PMID:14988359

  3. Pediatric trauma resuscitation: initial fluid management.

    PubMed

    Schweer, Lynn

    Fluid management is a vital component in the resuscitative care of the injured child. The goal of fluid resuscitation is to restore tissue perfusion without compromising the body's natural compensatory mechanism. Recent literature has questioned the timing, type, and amount of fluid administration during the resuscitative phase. When managing a pediatric resuscitation, it is imperative to use a variety of age-appropriate physiologic parameters because reliance on blood pressure alone will lead to delayed recognition of shock. Establishing vascular access, via peripheral intravenous, central venous, or intraosseous catheter, should be a high nursing priority. Hemorrhage control and fluid resuscitation of an injured child remains a top priority of trauma care. Early intravenous access with appropriate fluid administration continues to be a universal treatment for the hypotensive trauma patient. Fluid resuscitation in the early phase of care, whether in the field, emergency department, or operating room, should be targeted toward perfusing critical organs, such as the brain and heart. Once obvious bleeding is controlled, the overall goal for fluid management centers on maintaining oxygen delivery to perfuse vital structures with enough oxygen and energy substrates to maintain cellular function, thus avoiding tissue ischemia. However, specific issues around timing and type of fluid administration, once thought to be straightforward, have triggered increasing investigation of current beliefs.

    Patients with pulmonary thromboembolism (PE) often decompensate suddenly, and once hemodynamic compromise has developed, mortality is extremely high. Currently, thrombolytic therapy for PE is still controversial. We retrospectively evaluated 34 patients with PE between January 2010 and December 2013 in the Department of Pulmonary Medicine, Medical Park Samsun Hospital, Samsun, Turkey. The demographic and disease characteristics of patients who received thrombolytic treatment were retrospectively analyzed. The female to male ratio was 19/15 and the mean age was 63.1±13.2 years. PE diagnosis was made using echocardiography (64.7%) or contrast-enhanced thorax computed tomography with echocardiography (32.4%). Twenty-two (64.7%) patients went into the cardiopulmonary arrest due to massive PE and 17 (50%) patients recovered without sequelae. Eleven (32.4%) patients were diagnosed with massive PE during cardiopulmonary arrest with clinical and echocardiographic findings. Alteplase (recombinant tissue plasminogen activator [rt-PA]) was administered during cardiopulmonary resuscitation (CPR) and four (36.3%) patients responded and survived without sequelae. The complications of rt-PA treatment were hemorrhage in five (14.7%) patients and allergic reactions in two (5.9%) patients. There was no mortality due to rt-PA treatment complications. In conclusion, mortality due to massive PE is much more than estimated and alteplase can be used safely in patients with massive PE. This thrombolytic treatment was not associated with any fatal hemorrhage complication. If there is any sign of acute PE, echocardiography should be used during cardiopulmonary arrest/instability. Alteplase should be given to patients with suspected massive PE.

  11. 'Scoop and run' strategy for a resuscitative sternotomy following unstable penetrating chest injury.

    2010-03-01

    The optimal management strategy of an unstable penetrating thoracic trauma remains a debate. It is unclear whether a 'stay and treat' or 'scoop and run' to the nearest operating theatre with cardiothoracic expertise is the best strategy. We describe a successful outcome of a young patient with injuries to the left internal mammary artery, upper lobe and main pulmonary artery following a stab injury to his left chest. He was transferred to the nearest cardiac centre for emergency sternotomy. Thoracotomy is the classical surgical approach in emergency setting but sternotomy allows adequate exposure to repair any cardiac injury, institution of cardiopulmonary bypass, and careful inspection of the mediastinal structures to prevent any late complications including pulmonary artery pseudoaneurysm. An immediate transfer, where possible, to the nearest trauma centre with cardiothoracic expertise for 'resuscitative' sternotomy is advocated in penetrating thoracic injury for optimal outcome. An emergency room thoracotomy should be reserved to those in the extremis.

    The readjustment of cardiopulmonary variables in human volunteers at various tilt angles on a tilt board is studied. Five healthy subjects (18-31 yr) with thorough knowledge of the experimental protocol are tested, passively tilted from the supine to the upright position in 15-deg increments in random sequence. The parameters measured are cardiac output (Q), heart rate (HR), stroke volume (SV), minute and alveolar ventilation /V(E) and V(A)/, functional residual capacity (FRC), and arterial-end-tidal P(CO2) pressure difference. It is found that changes in Q and FRC are linearly related to the sine of the tilt angle, indicating that either reflexes are absent or their net effect is proportional to the effects of gravity. This is clearly not the case for other variables /HR, SV, V(E), V(A)/, where it is possible to demonstrate threshold values for the appearance of secondary changes.

  13. Mini cardiopulmonary bypass: Anesthetic considerations

    2012-01-01

    This review article is going to elaborate on the description, components, and advantages of mini-cardiopulmonary bypass (mini-CPB), with special reference to the anesthetic management and fast track anesthesia with mini-CPB. There are several clinical advantages of mini-CPB like, reduced inflammatory reaction to the pump, reduced need for allogenic blood transfusion and lower incidence of postoperative neurological complications. There are certainly important points that have to be considered by anesthesiologists to avoid sever perturbation in the cardiac output and blood pressure during mini-CPB. Fast-track anesthesia provides advantages regarding fast postoperative recovery from anesthesia, and reduction of postoperative ventilation time. Mini bypass offers a sound alternative to conventional CPB, and has definite advantages. It has its limitations, but even with that it has a definite place in the current practice of cardiac surgery.

    2012-01-01

    Infants born with hypoplastic left heart syndrome or other lesions resulting in a single right ventricle face the highest risk of mortality among all forms of congenital heart disease. Before the modern era of surgical palliation, these conditions were universally lethal; recent refinements in surgical technique and perioperative management have translated into dramatic improvements in survival. Nonetheless, these infants remain at a high risk of morbidity and mortality, and an appreciation of single ventricle physiology is fundamental to the care of these high-risk patients. Herein, resuscitation and perioperative management of infants with hypoplastic left heart syndrome are reviewed. Basic neonatal and pediatric life support recommendations are summarized, and perioperative first-stage clinical management strategies are reviewed.

    Background The neonatal resuscitation program (NRP) recommends close monitoring of oxygenation during the resuscitation of newborns using a pulse oximeter. However, there are no guidelines for monitoring carbon dioxide (CO2) to assess ventilation. Considering that cerebral blood flow (CBF) correlates directly with PaCO2, continuous capnography monitoring of end-tidal CO2 (ETCO2) may limit fluctuations in PaCO2 and, therefore, CBF during resuscitation of asphyxiated infants. Objective To evaluate if continuous monitoring of ETCO2 with capnography during resuscitation of asphyxiated term lambs with meconium aspiration will prevent fluctuations in PaCO2 and carotid arterial blood flow (CABF). Methods Fifty-four asphyxiated term lambs with meconium aspiration syndrome were mechanically ventilated from birth to 60 min of age. Ventilatory parameters were adjusted based on clinical observation (chest excursion) and frequent arterial blood gas analysis in 24 lambs (control group) and 30 lambs (capnography group) received additional continuous ETCO2 monitoring. Left CABF was monitored. We aimed to maintain PaCO2 between 35–50 mmHg and ETCO2 between 30–45 mmHg. Results There was a significant correlation between ETCO2 and PaCO2 (R=0.7, p<0.001), between PaCO2 and carotid flow (R=0.52, p<0.001), and between ETCO2 and carotid flow (R=0.5, p<0.001). PaCO2 and CABF during the first 60 minutes of age showed significantly higher fluctuation in the control group compared to the capnography group. Conclusion Continuous monitoring of ETCO2 using capnography with mechanical ventilation during and after resuscitation in asphyxiated term lambs with meconium aspiration limits fluctuations in PaCO2 and CABF, and may potentially limit brain injury.

    Objective To describe the association of lactate levels within the first 12 hours after successful resuscitation from pediatric cardiopulmonary arrest with hospital mortality. Design Retrospective cohort study. Setting Fifteen children’s hospital associated with the Pediatric Emergency Care Applied Research Network. Patients Patients between 1 day and 18 years old who had a cardiopulmonary arrest, received chest compressions more than 1 minute, had a return of spontaneous circulation more than 20 minutes, and had lactate measurements within 6 hours of arrest. Interventions None. Measurements and Main Results Two hundred sixty-four patients had a lactate sampled between 0 and 6 hours (lactate0–6) and were evaluable. Of those, 153 patients had a lactate sampled between 7 and 12 hours (lactate7–12). One hundred thirty-eight patients (52%) died. After controlling for arrest location, total number of epinephrine doses, initial rhythm, and other potential confounders, the odds of death per 1 mmol/L increase in lactate 0–6 was 1.14 (1.08, 1.19) (p < 0.001) and the odds of death per 1 mmol/L increase in lactate7–12 was 1.20 (1.11, 1.30) (p < 0.0001). Area under the curve for in-hospital arrest mortality for lactate0–6 was 0.72 and for lactate7–12 was 0.76. Area under the curve for out-of-hospital arrest mortality for lactate0–6 was 0.8 and for lactate7–12 was 0.75. Conclusions Elevated lactate levels in the first 12 hours after successful resuscitation from pediatric cardiac arrest are associated with increased mortality. Lactate levels alone are not able to predict outcomes accurately enough for definitive prognostication but may approximate mortality observed in this large cohort of children’s hospitals.

    The present survey was carried out to investigate the prevalence of cardiopulmonary helminths in red foxes in Pyrenees area and to evaluate the role of foxes in the eco-epidemiology of these nematodes. Hearts and entire respiratory tracts were obtained from 87 foxes from Vall d'Aran region, Pyrenees, Catalonia, north-eastern Spain. The cardiopulmonary tracts were dissected, flushed and examined for nematodes using sedimented flushing water. Of the 87 examined foxes, 53 (61%) were positive for cardiopulmonary helminths. The identified nematodes were Crenosoma vulpis (44.8%), Eucoleus aerophilus (29.9%) and Angiostrongylus vasorum (3.4%). Statistical differences were observed only on comparing age and C.vulpis prevalence, with young foxes being more infected than adults. The high prevalence of cardiopulmonary nematodes suggested that red foxes may play an important role in their transmission and maintenance in the studied area.

    The combined use of phenoxybenzamine and dopamine was applied in infants and children when it was difficult to come off cardiopulmonary bypass for low cardiac output. The rationale of this method is to prevent the alpha-adrenergic action of dopamine by phenoxybenzamine and to encourage the beta-adrenergic and direct specific action of dopamine. Dopamine was used in dosage of 10 to 30 micrograms/kg per min after the additional administration of a half of the initial dosage of phenoxybenzamine; this was infused by drip always in a dosage of 0.5 to 1.0 mg/kg during the first half of cardiopulmonary bypass. It was possible to come off cardiopulmonary bypass with a stable haemodynamic state (mean arterial pressure more than 60 mmHg and total peripheral vascular resistance less than 2000 bynes s cm-5) and a good urinary output.

    Since the initial hour after injury is the most crucial time for trauma patients, resuscitation technique is of vital importance. Standardized courses for first-hour management (ATLAS) have been widely accepted. A teaching format based upon video recording of every resuscitation has been developed. Tapes are reviewed by the staff and by the individuals involved in a particular resuscitation. In a weekly resuscitation review conference, actual footage is presented to the trauma team members, specific aspects of a resuscitation are critiqued, and supplemental didactic information is presented. Legal problems have been avoided by making the review and conference a part of the quality assurance process. Patient anonymity is preserved by positioning the video camera at the foot of the resuscitation bed. Tapes are erased after each conference. Video recording allows analysis of: 1) priorities during the resuscitation; 2) cognitive integration of the workup by the team leader; 3) physical integration of the workup by the team leader; 4) team member adherence to assigned responsibilities, resuscitation time, errors or breaks in technique; and 5) behavior change over time. In 3 1/2 years, more than 2,500 resuscitations have been recorded. Over a 3-month period, average resuscitation time to definitive care decreased for age- and injury severity-matched patient groups cared for by one team. Resuscitations have become more efficient and adherence to assigned responsibilities better. Weekly review of resuscitation contributes to improved technique and trauma care.

    For almost 25 years, the Neonatal Resuscitation Program of the American Academy of Pediatrics has provided educational tools that are used in the United States and throughout the world to teach neonatal resuscitation. Over that time period, the guidelines for resuscitation have been increasingly evidence-based and a formal system has been established to determine which steps should be updated on the basis of available information. The most recent update occurred in 2010. This article describes the evidence review process and the specific evidence that lead to a number of significant changes in practice that were included in the 2010 guidelines.

    2017-02-16

    Cardiac arrest is the leading cause of death in Europe and the United States. Many patients who are initially resuscitated die in the hospital, and hospital survivors often have substantial neurologic dysfunction. Most cardiac arrests are caused by coronary artery disease; patients with coronary artery disease likely benefit from early coronary angiography and intervention. After resuscitation, cardiac arrest patients remain critically ill and frequently suffer cardiogenic shock and multiorgan failure. Early cardiopulmonary stabilization is important to prevent worsening organ injury. To achieve best patient outcomes, comprehensive critical care management is needed, with primary goals of stabilizing hemodynamics and preventing progressive brain injury. Targeted temperature management is frequently recommended for comatose survivors of cardiac arrest to mitigate the neurologic injury that drives outcomes. Accurate neurologic assessment is central to managing care of cardiac arrest survivors and should combine physical examination with objective neurologic testing, with the caveat that delaying neurologic prognosis is essential to avoid premature withdrawal of supportive care. A combination of clinical findings and diagnostic results should be used to estimate the likelihood of functional recovery. This review focuses on recent advances in care and specific cardiac intensive care strategies that may improve morbidity and mortality for patients after cardiac arrest.

  6. Identifying Prognostic Criteria for Survival after Resuscitation Assisted by Extracorporeal Membrane Oxygenation

    To improve survival rates during CPR, some patients are put on extracorporeal membrane oxygenation (ECMO). Among children who have undergone ECMO cardiopulmonary resuscitation (ECPR), the overall rate of survival to discharge is close to 40%. However, despite its wide acceptance and use, the appropriate indications and organizational requirements for ECPR have yet to be defined. Our objective was to assess the clinical outcomes of children after ECPR and to determine pre-ECPR prognostic factors for survival to guide its indication. Among the 19 patients who underwent ECPR between 2008 and 2014 in our center, 16 patients (84%, 95% confidence interval: 62–95%) died during their hospital stay, including nine (47%) who were on ECMO and seven (37%) after successful weaning from ECMO. All three survivors had normal cognitive status, but one child suffered from spastic quadriplegia. Survivors tended to have lower lactate, higher bicarbonate, and higher pH levels before ECMO initiation, as well as shorter length of resuscitation. In conclusion, in our center, ECPR has a poorer outcome than expected. Therefore, it might be important to identify, a priori, patients who might benefit from this treatment. PMID:27006826

    Objective Pulmonary edema is frequently observed after a successful resuscitation in out-of-hospital cardiac arrest (OHCA) patients. Currently, its risk factors and prognostic implications are mostly unknown. Methods Adult OHCA patients with a presumed cardiac etiology who achieved sustained return of spontaneous circulation (ROSC) in emergency department were retrospectively analyzed. The patients were grouped according to the severity of consolidation on their initial chest X-ray (group I, no consolidation; group II, patchy consolidations; group III, consolidation involving an entire lobe; group IV, total white-out of any lung). The primary objective was to identify the risk factors of developing severe pulmonary edema (group III or IV). The secondary objective was to evaluate the association between long-term prognosis and the severity of pulmonary edema. Results One hundred and seven patients were included. Total duration of cardiopulmonary resuscitation (CPR) and initial pCO2 level were both independent predictors of developing severe pulmonary edema with their odds ratio (OR) being 1.02 (95% confidence interval [CI], 1.00 to 1.04; per 1 minute) and 1.04 (95% CI, 1.01 to 1.07; per 1 mmHg), respectively. The long term prognosis was significantly poor in patients with severe pulmonary edema with a OR for good outcome (6-month cerebral performance category 1 or 2) being 0.22 (95% CI, 0.06 to 0.79) in group III and 0.16 (95% CI, 0.04 to 0.63) in group IV compared to group I. Conclusion The duration of CPR and initial pCO2 level were both independent predictors for the development of severe pulmonary edema after resuscitation in emergency department. The severity of the pulmonary edema was significantly associated with long-term outcome. PMID:27752581

    Abstract Aims and objectives The aim of this paper is to determine the influence of do not attempt cardiopulmonary resuscitation (DNACPR) orders and the Universal Form of Treatment Options (‘UFTO’: an alternative approach that contextualizes the resuscitation decision within an overall treatment plan) on nurses' decision making about a deteriorating patient. Methods An online survey with a developing case scenario across three timeframes was used on 231 nurses from 10 National Health Service Trusts. Nurses were randomised into three groups: DNACPR, the UFTO and no‐form. Statements were pooled into four subcategories: Increasing Monitoring, Escalating Concern, Initiating Treatments and Comfort Measures. Results Reported decisions were different across the three groups. Nurses in the DNACPR group agreed or strongly agreed to initiate fewer intense nursing interventions than the UFTO and no‐form groups (P < 0.001) overall and across subcategories of Increase Monitoring, Escalate Concern and Initiate Treatments (all P < 0.001). There was no difference between the UFTO and no‐form groups overall (P = 0.795) or in the subcategories. No difference in Comfort Measures were observed (P = 0.201) between the three groups. Conclusion The presence of a DNACPR order appears to influence nurse decision making in a deteriorating patient vignette. Differences were not observed in the UFTO and no‐form group. The UFTO may improve the way nurses modulate their behaviours towards critically ill patients with DNACPR status. More hospitals should consider adopting an approach where the resuscitation decisions are contextualised within overall goals of care. PMID:27237130

    Background Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions. Methods This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching. Results In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1%) underwent emergency resuscitative thoracotomy and 893 (64.9%) received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001) and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001). Multivariable generalized mixed-effects regression analysis with and without a propensity score-matched dataset revealed that the odds ratio for an unfavorable survival rate after 24 h

    Shock, or tissue hypoperfusion, is a frequent complication from traumatic injury. Despite the etiology of the shock state, there is always some component of hypovolemia. The body's innate ability to compensate for impaired perfusion may mask clinical signs, leading to delays in treatment. This article presents an overview of these compensatory mechanisms and resuscitation strategies from the vantage point of routine hemodynamic monitoring.

    Timely fluid administration is crucial to maintain tissue perfusion in septic shock patients. However, the question concerning which fluid should be used for septic shock resuscitation remains a matter of debate. A growing body of evidence suggests that the type, amount and timing of fluid administration during the course of sepsis may affect patient outcomes. Crystalloids have been recommended as the first-line fluids for septic shock resuscitation. Nevertheless, given the inconclusive nature of the available literature, no definitive recommendations about the most appropriate crystalloid solution can be made. Resuscitation of septic and non-septic critically ill patients with unbalanced crystalloids, mainly 0.9% saline, has been associated with a higher incidence of acid-base balance and electrolyte disorders and might be associated with a higher incidence of acute kidney injury. This can result in greater demand for renal replacement therapy and increased mortality. Balanced crystalloids have been proposed as an alternative to unbalanced solutions in order to mitigate their detrimental effects. Nevertheless, the safety and effectiveness of balanced crystalloids for septic shock resuscitation need to be further addressed in a well-designed, multicenter, pragmatic, randomized controlled trial.

    2016-01-01

    The American Heart Association reports the annual incidence of out-of-hospital cardiopulmonary arrests (OHCA) is greater than 300,000 with a survival rate of 9.5%. Bystander cardiopulmonary resuscitation (CPR) saves one life for every 30, with a 10% decrease in survival associated with every minute of delay in CPR initiation. Bystander CPR and training vary widely by region. We conducted a retrospective study of 320 persons who suffered OHCA in South Florida over 25 months. Increased survival, overall and with bystander CPR, was seen with increasing income (p = 0.05), with a stronger disparity between low- and high-income neighborhoods (p = 0.01 and p = 0.03, resp.). Survival with bystander CPR was statistically greater in white- versus black-predominant neighborhoods (p = 0.04). Increased survival, overall and with bystander CPR, was seen with high- versus low-education neighborhoods (p = 0.03). Neighborhoods with more high school age persons displayed the lowest survival. We discovered a significant disparity in OHCA survival within neighborhoods of low-income, black-predominance, and low-education. Reduced survival was seen in neighborhoods with larger populations of high school students. This group is a potential target for training, and instruction can conceivably change survival outcomes in these neighborhoods, closing the gap, thus improving survival for all. PMID:27379186

    Postnatal cardiopulmonary adaptations to high altitude constitute a key component of any set of responses developed to face high altitude hypoxia. Such responses are required ultimately to meet the energy demands necessary for adequate functioning at cell and organism level. After a brief insight on general and cardiopulmonary comparative studies in growing and adult organisms, differences and possible explanations for varying cardiopulmonary pathology, pulmonary artery hypertension, persistent right ventricular predominance and subacute high altitude pulmonary hypertension in different populations of children living at high altitude are discussed. Potential long-term implications of early chronic hypoxic exposure on later diseases are also presented. It is hoped that this review will help the practicing physician working at high altitude to make informed decisions concerning individual pediatric patients, specifically with regard to diagnosis and management of altitude-related cardiopulmonary pathology. Finally, plausibility and the knowledge-base of public health interventions to reduce the risks posed by suboptimal or inadequate postnatal cardiopulmonary responses to high altitude are discussed.

    2016-09-01

    Although there are known detrimental effects of obesity on the heart and lungs, few data exist showing obesity as risk factor for cardiopulmonary disorders in dogs and cats. It is probable that increased abdominal fat is detrimental as it is in humans, and there is evidence of negative effects of increased intrathoracic fat. As well as physical effects of fat, increased inflammatory mediators and neurohormonal effects of obesity likely contribute to cardiopulmonary disorders. Weight loss in overweight individuals improves cardiac parameters and exercise tolerance. Obesity in patients with obstructive airway disorders is recognized to increase disease severity.

    AIM To determine the feasibility of introducing video recording (VR) of neonatal resuscitation (NR) in a perinatal centre. METHODS This was a prospective cohort quality improvement study on preterm infants and their caregivers. Based on evidence and experience of other centers using VR intervention, a contextually relevant implementation and evaluation strategy was designed in the planning phase. The components of intervention were pre-resuscitation team huddle, VR of NR and video debriefing (VD), all occurring on the same day. Various domains of feasibility and sustainability as well as feasibility criteria were predefined. Data for analysis was collected using quantitative and qualitative methods. RESULTS Seventy-one caregivers participated in VD of 14 NRs facilitated by six trained instructors. Ninety-one percent of caregivers perceived enhanced learning and patient safety and, 48 issues were identified related to policy, caregiver roles, and latent safety threats. Ninety percent of caregivers expressed their willingness to participate in VD activity and supported the idea of integrating it into a resuscitation team routine. Eighty-three percent and 50% of instructors expressed satisfaction with video review software and quality of audio VR. No issues about maintenance of infant or caregivers’ confidentiality and erasure of videos were reported. Criteria for feasibility were met (refusal rate of < 10%, VR performed on > 50% of occasions, and < 20% caregivers’ perceiving a negative impact on team performance). Necessary adaptations to enhance sustainability were identified. CONCLUSION VR of NR as a standard of care quality assurance activity to enhance caregivers’ learning and create opportunities that improve patient safety is feasible. Despite its complexity with inherent challenges in implementation, the intervention was acceptable, implementable, and potentially sustainable with adaptations. PMID:28224098

    Airway management is an important component of resuscitation from out-of-hospital cardiac arrest (OHCA). The optimal approach to advanced airway management is unknown. The Pragmatic Airway Resuscitation Trial (PART) will compare the effectiveness of endotracheal intubation (ETI) and Laryngeal Tube (LT) insertion upon 72-hour survival in adult OHCA. Encompassing United States Emergency Medical Services agencies affiliated with the Resuscitation Outcomes Consortium (ROC), PART will use a cluster-crossover randomized design. Participating subjects will include adult, non-traumatic OHCA requiring bag-valve-mask ventilation. Trial interventions will include 1) initial airway management with ETI and 2) initial airway management with LT. The primary and secondary trial outcomes are 72-hour survival and return of spontaneous circulation. Additional clinical outcomes will include airway management process and adverse events. The trial will enroll a total of 3,000 subjects. Results of PART may guide the selection of advanced airway management strategies in OHCA. PMID:26851059

    Emboli in the brain microvasculature may inhibit brain activity during cardiopulmonary bypass. Such hypothetical blockade, if confirmed, may be responsible for the reduction of cerebral metabolic rate for glucose observed in animals subjected to cardiopulmonary bypass. In previous studies of cerebral blood flow during bypass, brain microcirculation was not evaluated. In the present study in animals (pigs), reduction of the number of perfused capillaries was estimated by measurements of the capillary diffusion capacity for hydrophilic tracers of low permeability. Capillary diffusion capacity, cerebral blood flow, and cerebral metabolic rate for glucose were measured simultaneously by the integral method, different tracers being used with different circulation times. In eight animals subjected to normothermic cardiopulmonary bypass, and seven subjected to hypothermic bypass, cerebral blood flow, cerebral metabolic rate for glucose, and capillary diffusion capacity decreased significantly: cerebral blood flow from 63 to 43 ml/100 gm/min in normothermia and to 34 ml/100 gm/min in hypothermia and cerebral metabolic rate for glucose from 43.0 to 23.0 mumol/100 gm/min in normothermia and to 14.1 mumol/100 gm/min in hypothermia. The capillary diffusion capacity declined markedly from 0.15 to 0.03 ml/100 gm/min in normothermia but only to 0.08 ml/100 gm/min in hypothermia. We conclude that the decrease of cerebral metabolic rate for glucose during normothermic cardiopulmonary bypass is caused by interruption of blood flow through a part of the capillary bed, possibly by microemboli, and that cerebral blood flow is an inadequate indicator of capillary blood flow. Further studies must clarify why normal microvascular function appears to be preserved during hypothermic cardiopulmonary bypass.

    Infant botulism is a rare disease that affects infant less than 12 months of age. The illness results from absorption of botulinum toxin produced in situ by neurotoxigenic clostridia that can temporarily colonize the intestinal tract of infants. To date, all inhabited continents except Africa have reported cases of infant botulism. Recognition of cases seem directly related to physician awareness and clinical suspicion. This review summarizes microbiological, clinical and epidemiological features of infant botulism.

    Patients with multiple traumas associated with cardiopulmonary failure have a high mortality rate; however, such patients can be temporarily stabilized using extracorporeal membrane oxygenation (ECMO), providing a bridge to rescue therapy. Using a retrospective study design, we aimed to clarify the prognostic factors of post-traumatic ECMO support.From March 2006 to July 2016, 43 adult patients (mean age, 37.3 ± 15.2 years; 7 females [16.3%]) underwent ECMO because of post-traumatic cardiopulmonary failure. Pre-ECMO demographics, peri-ECMO events, and post-ECMO recoveries were compared between survivors and nonsurvivors.The most common traumatic insult was traffic collision (n = 30, 69.8%), and involved injury areas included the chest (n = 33, 76.7%), head (n = 14, 32.6%), abdomen (n = 21, 48.8%), and fractures (n = 21, 48.8%). Fifteen patients (34.9%) underwent cardiopulmonary resuscitation and 22 (51.2%) received rescue interventions before ECMO deployment. The mean time interval between trauma and ECMO was 90.6 ± 130.1 hours, and the mode of support was venovenous in 26 patients (60.5%). A total of 26 patients (60.5%) were weaned off of ECMO and 22 (51.6%) survived to discharge, with an overall mean support time of 162.9 ± 182.7 hours. A multivariate regression analysis identified 2 significant predictors for in-hospital mortality: an injury severity score (ISS) >30 (odds ratio [OR], 9.48; 95% confidence interval [CI], 1.04-18.47; P = 0.042), and the requirement of renal replacement therapy (RRT) during ECMO (OR, 8.64; 95% CI, 1.73-26.09; P = 0.020). These two factors were also significant for the 1-year survival (ISS >30: 12.5%; ISS ≤30, 48.1%, P = 0.001) (RRT required, 15.0%; RRT not required, 52.2%, P = 0.006).Using ECMO in selected traumatized patients with cardiopulmonary failure can be a salvage therapy.

    This article reviews the evidence for an association between infant colic and migraine. Infant colic, or excessive crying in an otherwise healthy and well-fed infant, affects approximately 5–19% of infants. Multiple case-control studies, a cross-sectional study, and a prospective cohort study have all found an association between infant colic and migraine. While infant colic is often assumed to have a gastrointestinal cause, several treatment trials aimed at gastrointestinal etiologies have been negative. Teaching parents how best to respond to inconsolable crying may be helpful and important for preventing shaken baby syndrome. Given accumulating evidence for a connection between infant colic and pediatric migraine, future studies should examine migraine-oriented treatments for infant colic. Infant colic should be moved into the main body of International Classification of Headache Disorders (ICHD-III beta) as one of the “Episodic syndromes that may be associated with migraine”.

    One of the major advances in medicine has been the use of cardiopulmonary resuscitation (CPR) procedure since the 1960s in order to save human lives. This procedure has so far saved thousands of lives. Although CPR has helped to save lives, in some cases, it prolongs the process of dying, suffering, and pain in patients. This study was conducted to explain the experience of Iranian physicians regarding do not resuscitate order (DNR). This study was a directed qualitative content analysis which analyzed the perspective of 8 physicians on different aspects of DNR guidelines. Semi-structured, in-depth interview was used to collect data (35 to 60 minutes). First, literature review of 6 main categories, including clinical, patient and family, moral, legal, religious, and economic aspects, was carried out through content analysis. At the end of each session, interviews were transcribed verbatim. Then, the text was broken into the smallest meaningful unit (code) and the codes were classified into main categories. The codes were classified into 6 main categories, which were extracted from the literature. In the clinical domain 4 codes, in patient and family 3 codes, in moral domain 4 codes, in religious domain 3 codes, and in economic domain 1 code were extracted. According to the findings of this study, it can be said that Iranian physicians approve the DNR order as it provides dying patients with a dignified death. However, they do not issue DNR order due to the lack of legal and religious support. Nevertheless, if legislators and the Iranian jurisprudence pass a bill in this regard, physicians with the help of clinical guidelines can issue DNR order for dying patients who require it.

    Background The themes of qualitative assessments that characterize the experience of family members offered the choice of observing cardiopulmonary resuscitation (CPR) of a loved one have not been formally identified. Methods and Findings In the context of a multicenter randomized clinical trial offering family members the choice of observing CPR of a patient with sudden cardiac arrest, a qualitative analysis, with a sequential explanatory design, was conducted. The aim of the study was to understand family members’ experience during CPR. All participants were interviewed by phone at home three months after cardiac arrest. Saturation was reached after analysis of 30 interviews of a randomly selected sample of 75 family members included in the trial. Four themes were identified: 1- choosing to be actively involved in the resuscitation; 2- communication between the relative and the emergency care team; 3- perception of the reality of the death, promoting acceptance of the loss; 4- experience and reactions of the relatives who did or did not witness the CPR, describing their feelings. Twelve sub-themes further defining these four themes were identified. Transferability of our findings should take into account the country-specific medical system. Conclusions Family presence can help to ameliorate the pain of the death, through the feeling of having helped to support the patient during the passage from life to death and of having participated in this important moment. Our results showed the central role of communication between the family and the emergency care team in facilitating the acceptance of the reality of death. PMID:27253993

    2016-11-01

    The goal of the Neonatal Resuscitation Program is to have a trained provider in neonatal resuscitation at every delivery. The Neonatal Resuscitation Program develops its course content on review of the scientific evidence available for the resuscitation of newborns. Just as importantly, the educational structure and delivery of the course are based on evidence and educational theory. Thus, as simulation became a more accepted model in medical education and evidence was developing suggesting benefit of simulation, the Neonatal Resuscitation Program officially added simulation into its courses in 2010. Simulation-based medical education is now an integral part of the Neonatal Resuscitation Program courses both in teaching the psychomotor skills as well as the teamwork skills needed for effective newborn resuscitations. While there is evidence, as in other fields, suggesting that simulation for teaching newborn resuscitation is beneficial whether using high- or low-technology manikins or video-assisted debriefing or not, there are still many unanswered questions as to best practice and patient outcome effects.

    Regionalization of medical resources by designating specialty receiving centers, such as trauma and stroke centers, within emergency medical services (EMS) systems is intended to ensure the highest-quality patient care in the most efficient and fiscally responsible fashion. Significant advances in the past decade such as induction of therapeutic hypothermia following resuscitation from cardiac arrest and a time-driven, algorithmic approach to management of septic patients have created compelling arguments for similar designation for specialized resuscitative interventions. Resuscitation of critically ill patients is both labor- and resource-intensive. It can significantly interrupt emergency department (ED) patient throughput. In addition, clinical progress in developing resuscitation techniques is often dependent on the presence of a strong research infrastructure to generate and validate new therapies. It is not feasible for many hospitals to make the commitment to care for large numbers of critically ill patients and the accompanying investigational activities, whether in the prehospital, ED, or inpatient arena. Because of this, the question of whether EMS systems should designate specific hospitals as "resuscitation centers" has now come center stage. Just as EMS systems currently delineate criteria and monitor compliance for trauma, ST-elevation myocardial infarction (STEMI), and stroke centers, strong logic now exists to develop similar standards for resuscitation facilities. Accordingly, this discussion reviews the current applicable trends in resuscitation science and presents a rationale for resuscitation center designation within EMS systems. Potential barriers to the establishment of such centers are discussed and strategies to overcome them are proposed.

    We present a case that elegantly illustrates the utility of two novel noninvasive imaging techniques, computed tomography (CT) coronary angiography and cardiac MRI, in the diagnosis and management of a 27-year-old man with exertion-induced cardiac arrest caused by an anomalous right coronary artery. CT coronary angiography with 3D reformatting delineated the interarterial course of an anomalous right coronary artery compressed between the aorta and pulmonary artery, whereas cardiac MRI showed a small myocardial infarction in the right coronary artery territory not detected on echocardiography. This case highlights the value of novel multimodality imaging techniques in the risk stratification and management of patients with resuscitated cardiac arrest.

    The baroreflex, chemoreflex, pulmonary reflexes, Bezold-Jarisch and Bainbridge reflexes and their interaction with local mechanisms, are a demonstration of the richness of cardiovascular responses that occur in human beings. As well as these, the anesthesiologist must contend with other variables that interact by attenuating or accentuating cardiopulmonary reflexes such as, anesthetic drugs, surgical manipulation, and patient positioning. In the present article we review these reflexes and their clinical relevance in anesthesiology.

    The Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) is a major mediator of physiological glutamate signaling, but its role in pathological glutamate signaling (excitotoxicity) remains less clear, with indications for both neuro-toxic and neuro-protective functions. Here, the role of CaMKII in ischemic injury is assessed utilizing our mouse model of cardiac arrest and cardiopulmonary resuscitation (CA/CPR). CaMKII inhibition (with tatCN21 or tatCN19o) at clinically relevant time points (30 min after resuscitation) greatly reduces neuronal injury. Importantly, CaMKII inhibition also works in combination with mild hypothermia, the current standard of care. The relevant drug target is specifically Ca(2+)-independent "autonomous" CaMKII activity generated by T286 autophosphorylation, as indicated by substantial reduction in injury in autonomy-incompetent T286A mutant mice. In addition to reducing cell death, tatCN19o also protects the surviving neurons from functional plasticity impairments and prevents behavioral learning deficits, even at extremely low doses (0.01 mg/kg), further highlighting the clinical potential of our findings.

  4. The role of simulation in teaching pediatric resuscitation: current perspectives

    The use of simulation for teaching the knowledge, skills, and behaviors necessary for effective pediatric resuscitation has seen widespread growth and adoption across pediatric institutions. In this paper, we describe the application of simulation in pediatric resuscitation training and review the evidence for the use of simulation in neonatal resuscitation, pediatric advanced life support, procedural skills training, and crisis resource management training. We also highlight studies supporting several key instructional design elements that enhance learning, including the use of high-fidelity simulation, distributed practice, deliberate practice, feedback, and debriefing. Simulation-based training is an effective modality for teaching pediatric resuscitation concepts. Current literature has revealed some research gaps in simulation-based education, which could indicate the direction for the future of pediatric resuscitation research. PMID:25878517

    Computer-based simulation has intuitive appeal to both educators and learners with the flexibility of time, place, immediate feedback, and self-paced and consistent curriculum. The purpose of this study was to assess the effects of computer-based simulation on nursing students' performance, self-efficacy, post-code stress, and satisfaction between computer-based simulation plus instructor-led cardiopulmonary resuscitation training group and instructor-led resuscitation training-only group. This study was a nonequivalent control group posttest-only design. There were 213 second year nursing students randomly assigned to one of two groups: 109 nursing students with computer-based simulation or 104 with control group. Overall nursing students' performance score was higher in the computer-based simulation group than in the control group but reached no statistical significance (t = 1.086, p = .283). There were no significant differences in resuscitation-specific self-efficacy, post-code stress, and satisfaction between the two groups. Computer-based simulation combined with hands-on practice did not affect in nursing students' performance, self-efficacy, post-code stress, and satisfaction in nursing students. Further study must be conducted to inform instructional design and help integrate computer-based simulation and rigorous scoring rubrics.

    No specific treatment exists for poisoning with most fat-soluble drugs. Intravenous lipid emulsion (ILE) may be effective therapy against such drugs, but effects of ILE treatment are unclear. A 24-year-old woman with depression seen sleeping in the morning was found comatose in the evening, and an emerging lifesaving technologies service was called. After emerging lifesaving technologies departure to hospital, she stopped breathing, became pulseless, and cardiopulmonary life support was started immediately. Electrocardiographic monitoring showed asystole during resuscitation even after arrival at hospital. Empty packaging sheets of 60-tablet chlorpromazine (CPZ) (50 mg/tablet) and 66-tablet mirtazapine (MZP) (15 mg/tablet) found at the scene suggested drug-related cardiopulmonary arrest. Along with conventional administration of adrenaline (total dose, 5 mg), 20% Intralipid 100 mLwas given intravenously 8 minutes after hospital arrival and readministered 27 minutes after hospital arrival because of continued asystole. Return of spontaneous circulation occurred 29 minutes after arrival (70 minutes after cardiac arrest). The patient recovered without any major complications and was transferred to another hospital for psychiatric treatment 70 days after admission. Concentrations of CPZ and MZP were still high when return of spontaneous circulation was achieved with ILE. This case suggested the possible benefit of ILE in treating life threatening cardiotoxicity from CPZ and MZP overdose.

    Infant botulism is a paralytic syndrome which manifests as a result of ingesting spores of the toxin secreting bacterium Clostridium botulinum by infants. As opposed to botulism in adults, treating infant botulism with horse antiserum was not approved due to several safety issues. This restriction has led to the development of Human Botulism Immune Globulin Intravenous (BIG-IV; sells under BabyBIG). In this article we review infant botulism and the advantages of treating it with BIG-IV.

    Fluid resuscitation is essential for the survival of critically ill patients in shock, regardless of the origin of shock. A number of crystalloids and colloids (synthetic and natural) are currently available, and there is strong controversy regarding which type of fluid should be administered and the potential adverse effects associated with the use of these products, especially the development of renal failure requiring renal replacement therapy. Recently, several clinical trials and metaanalyses have suggested the use of hydroxyethyl starch (130/0.4) to be associated with an increased risk of death and kidney failure, and data have been obtained showing clinical benefit with the use of crystalloids that contain a lesser concentration of sodium and chlorine than normal saline. This new information has increased uncertainty among clinicians regarding which type of fluid should be used. We therefore have conducted a review of the literature with a view to developing practical recommendations on the use of fluids in the resuscitation phase in critically ill adults.

    All transcatheter aortic valve implantation (TAVI) cases are done in our hybrid operating room with a multidisciplinary team and a primed cardiopulmonary bypass (CPB) circuit on pump stand-by. We decided that we would resuscitate all patients undergoing a TAVI procedure via a transfemoral, transapical or transaortic approach, if required. Perfusion plays an essential role in providing rescue CPB for patient salvage when catastrophic complications occur. To coordinate the multidisciplinary effort, we have developed a written safety checklist that assigns a pre-determined role for team members for the rapid sequence initiation of CPB. Although many TAVI patients are not candidates for conventional aortic valve replacements, we feel strongly that rescue CPB should be offered to all TAVI patients to allow the correction of potentially reversible complications. This protocol is included in every surgical "Time Out" involving a TAVI procedure (Figure 1). The protocol has led to rapid and safe CPB initiation in less than five minutes of cardiac arrest. It has also led to a coordinated and consistent team, with pre-specified roles and improved communication. We discuss a case series of four TAVI patients who required emergent use of CPB. The first few cases did not have a written protocol. The experience from these cases led to the development of our protocol. We identified a lack of coordination, wasted movements, unnecessary delayed resuscitation and overall chaos, each of which was targeted for correction with the protocol. We will discuss the merits of the protocol in two recent TAVI cases which required emergent CPB.

    Children with significant envenomation require early first aid, resuscitation, and the administration of antivenom at the earliest possible time to survive. The case of a nine-month-old infant with life-threatening massive envenomation from the Sydney funnel-web spider (Atrax robustus) is presented. The infant was administered life-saving first aid (pressure immobilization bandage) and resuscitation measures prior to and during the administration of funnel-web-specific antivenom. The infant was discharged two days after the initial envenomation, without sequelae from the envenomation or antivenom. The survival of this infant is attributed to the immediate use of first aid, together with aggressive supportive measures and the administration of repeated doses of specific antivenom.

  18. The Significance of Strong Ion Gap for Predicting Return of Spontaneous Circulation in Patients with Cardiopulmonary Arrest

    Abstract Useful parameters that can predict return of spontaneous circulation (ROSC) in patients with cardiopulmonary arrest (CPA) have not been established. We previously reported the usefulness of anion gap (AG) and albumin-corrected anion gap (ACAG) calculated from a blood sample obtained on arrival at the hospital for the prediction of ROSC. Otherwise, it has been reported that strong ion gap (SIG), which shows the difference between the levels of fully dissociated cations and anions in the serum, is useful to predict the prognosis of critically ill patients. This was a prospective and observational clinical study. Patients with CPA transferred to the emergency department of our hospital between January 2013 and December 2014 were evaluated. Patients were divided into two groups: patients who obtained ROSC [ROSC(+) group] and those who did not [ROSC(−) group]. We compared AG, ACAG and SIG between the two groups. A total of 170 patients were enrolled. Fifty patients were included in the ROSC(+) group, and the remaining 120 in the ROSC(−) group. Both AG and ACAG were significantly better in the ROSC(+) group; however, there was no significant difference in SIG between the two groups. The area under the receiver operating characteristic curves (AUC) for ROSC of both AG and ACAG were almost the same (0.72 and 0.708, respectively); the AUC of SIG (0.57) was inferior to those of AG and ACAG. Our results suggest that AG and ACAG can better predict ROSC following cardiopulmonary resuscitation (CPR) compared with SIG.

  19. Fluid resuscitation in human sepsis: Time to rewrite history?

    PubMed

    Byrne, Liam; Van Haren, Frank

    2017-12-01

    Fluid resuscitation continues to be recommended as the first-line resuscitative therapy for all patients with severe sepsis and septic shock. The current acceptance of the therapy is based in part on long history and familiarity with its use in the resuscitation of other forms of shock, as well as on an incomplete and incorrect understanding of the pathophysiology of sepsis. Recently, the safety of intravenous fluids in patients with sepsis has been called into question with both prospective and observational data suggesting improved outcomes with less fluid or no fluid. The current evidence for the continued use of fluid resuscitation for sepsis remains contentious with no prospective evidence demonstrating benefit to fluid resuscitation as a therapy in isolation. This article reviews the historical and physiological rationale for the introduction of fluid resuscitation as treatment for sepsis and highlights a number of significant concerns based on current experimental and clinical evidence. The research agenda should focus on the development of hyperdynamic animal sepsis models which more closely mimic human sepsis and on experimental and clinical studies designed to evaluate minimal or no fluid strategies in the resuscitation phase of sepsis.

    An emergency thoracotomy may be life-saving by achieving four goals: (i) releasing cardiac tamponade, (ii) controlling haemorrhage, (iii) allowing access for internal cardiac massage and (iv) clamping the descending aorta to isolate circulation to the upper torso in damage control surgery. We theorize that a new goal should be achieving rapid, large-volume fluid resuscitation and we describe a technique to achieve this. PMID:27887010

    Introduction Leadership skills are described by the American College of Surgeons’ Advanced Trauma Life Support (ATLS) course as necessary to provide care for patients during resuscitations. However, leadership is a complex concept, and the tools used to assess the quality of leadership are poorly described, inadequately validated, and infrequently used. Despite its importance, dedicated leadership education is rarely part of physician training programs. The goals of this investigation were the following: 1. Describe how leadership and leadership style affect patient care; 2. Describe how effective leadership is measured; and 3. Describe how to train future physician leaders. Methods We searched the PubMed database using the keywords “leadership” and then either “trauma” or “resuscitation” as title search terms, and an expert in emergency medicine and trauma then identified prospective observational and randomized controlled studies measuring leadership and teamwork quality. Study results were categorized as follows: 1) how leadership affects patient care; 2) which tools are available to measure leadership; and 3) methods to train physicians to become better leaders. Results We included 16 relevant studies in this review. Overall, these studies showed that strong leadership improves processes of care in trauma resuscitation including speed and completion of the primary and secondary surveys. The optimal style and structure of leadership are influenced by patient characteristics and team composition. Directive leadership is most effective when Injury Severity Score (ISS) is high or teams are inexperienced, while empowering leadership is most effective when ISS is low or teams more experienced. Many scales were employed to measure leadership. The Leader Behavior Description Questionnaire (LBDQ) was the only scale used in more than one study. Seven studies described methods for training leaders. Leadership training programs included didactic teaching

    The aim of this study was to characterize attitudes and practices among health care providers (HCPs) in Mongolia regarding parental involvement in neonatal resuscitation (NR)-related decisions. A voluntary, anonymous questionnaire was administered to 210 HCPs across 19 of 21 Mongolia provinces. Eligible HCPs included midwives, neonatologists, pediatricians, and obstetricians involved in neonatal-perinatal care in both rural and urban hospitals. A total of 210 pediatric HCPs were surveyed and 100 % completed all questions (response rate 100 %). Despite the absence of nation-wide guidelines, NR is uniformly performed at 32-weeks gestation across HCP professions and across rural/urban settings. Most HCPs (67 %) indicate that parents should be counseled about resuscitation, but only 9 % ask the parents if they want their extremely premature child resuscitated and only 17 % counsel the parents prior to birth of an at-risk infant. Most HCPs (72 %) prefer to unilaterally decide when to withdraw NR, and only 28 % indicated that both parents should be involved in the decision. Following a newborn's death, 75 % of all HCPs reported that they do explain the death to parents, although only 28 % reported receiving any training in parental grief counseling. For HCPs in Mongolia, a discrepancy exists between the perceived value of parental involvement and the actual practice of NR-related counseling. This report is a necessary first step toward understanding the factors that influence NR-related practices in Mongolia, and may serve as model for collecting these types of data in other low and middle income countries.

    Both commercial aviation and resuscitation are complex activities in which team members must respond to unexpected emergencies in a consistent, high quality manner. Lives are at stake in both activities and the two disciplines have similar leadership structures, standard setting processes, training methods, and operational tools. Commercial aviation crews operate with remarkable consistency and safety, while resuscitation team performance and outcomes are highly variable. This commentary provides the perspective of two physician-pilots showing how commercial aviation training, operations, and safety principles can be adapted to resuscitation team training and performance.

    Cerebral blood flow was measured by xenon-133 washout in 13 patients 6-46 hours after being resuscitated from cardiac arrest. Patients regaining consciousness had relatively normal cerebral blood flow before regaining consciousness, but all patients who died without regaining consciousness had increased cerebral blood flow that appeared within 24 hours after resuscitation (except in one patient in whom the first measurement was delayed until 28 hours after resuscitation, by which time cerebral blood flow was increased). The cause of the delayed-onset increase in cerebral blood flow is not known, but the increase may have adverse effects on brain function and may indicate the onset of irreversible brain damage.

    Background Resuscitation promoting factors (RPF) are secreted proteins involved in reactivation of dormant actinobacteria, including Mycobacterium tuberculosis. They have been considered as prospective targets for the development of new anti-tuberculosis drugs preventing reactivation of dormant tubercle bacilli, generally associated with latent tuberculosis. However, no inhibitors of Rpf activity have been reported so far. The goal of this study was to find low molecular weight compounds inhibiting the enzymatic and biological activities of Rpfs. Methodology/Principal Findings Here we describe a novel class of 2-nitrophenylthiocyanates (NPT) compounds that inhibit muralytic activity of Rpfs with IC50 1–7 µg/ml. Fluorescence studies revealed interaction of active NPTs with the internal regions of the Rpf molecule. Candidate inhibitors of Rpf enzymatic activity showed a bacteriostatic effect on growth of Micrococcus luteus (in which Rpf is essential for growth protein) at concentrations close to IC50. The candidate compounds suppressed resuscitation of dormant (“non-culturable”) cells of M. smegmatis at 1 µg/ml or delayed resuscitation of dormant M. tuberculosis obtained in laboratory conditions at 10 µg/ml. However, they did not inhibit growth of active mycobacteria under these concentrations. Conclusions/Significance NPT are the first example of low molecular weight compounds that inhibit the enzymatic and biological activities of Rpf proteins. PMID:20016836

    Background: It is unknown whether this burden of disease of lower respiratory tract infections is comparable across the Canadian Arctic. The objectives of this surveillance study were to compare the rates of hospital admission for lower respiratory tract infection and the severity of infection across Arctic Canada, and to describe the responsible viruses. Methods: We performed a prospective multicentre surveillance study of infants less than 1 year of age admitted in 2009 with lower respiratory tract infection to all hospitals (5 regional, 4 tertiary) in the Northwest Territories, Nunavut and Nunavik to assess for regional differences. Nasopharyngeal aspirates were processed by means of a polymerase chain reaction respiratory viral panel, testing for 20 respiratory viruses and influenza A (H1N1). The role of coinfection was assessed by means of regression analysis for length of stay (short: < 7 d; long: > 14 d). Outcomes compared included rates of lower respiratory tract infection, respiratory syncytial virus infection, transfer to tertiary hospital and severe lower respiratory tract infection (respiratory failure, intubation and mechanical ventilation, and/or cardiopulmonary resuscitation). Results: There were 348 admissions for lower respiratory tract infection in the population of interest in 2009. Rates of admission per 1000 live births varied significantly, from 39 in the Northwest Territories to 456 in Nunavik (p < 0.001). The rates of tertiary admissions and severe lower respiratory tract infection per 1000 live births in the Northwest Territories were 5.6 and 1.4, respectively, compared to 55.9 and 17.1, respectively, in Nunavut and 52.0 and 20.0, respectively, in Nunavik (p ≤ 0.001). Respiratory syncytial virus was the most common virus identified (124 cases [41.6% of those tested]), and coinfection was detected in 51 cases (41.1%) of infection with this virus. Longer length of stay was associated with coinfection (odds ratio [OR] 2.64) and underlying

    Sarcoidosis is a multi-system disease with a wide range of phenotypes. Pulmonary involvement is the most frequently identified target for sarcoidosis and is responsible for the majority of deaths. Cardiac sarcoid is less commonly identified, may be occult, is significantly influenced by race, and can portend an unpredictable and sometimes fatal outcome. Sarcoidosis remains an enigmatic disease spectrum of unknown aetiology, frequently difficult to diagnose and with a variable disease course. This article summarises current views on the diagnosis and management of cardiopulmonary involvement.

    Objective To provide a brief review of the development of cardiopulmonary bypass. Methods A review of the literature on the development of extracorporeal circulation techniques, their essential role in cardiovascular surgery, and the complications associated with their use, including hemolysis and inflammation. Results The advancement of extracorporeal circulation techniques has played an essential role in minimizing the complications of cardiopulmonary bypass, which can range from various degrees of tissue injury to multiple organ dysfunction syndrome. Investigators have long researched the ways in which cardiopulmonary bypass may insult the human body. Potential solutions arose and laid the groundwork for development of safer postoperative care strategies. Conclusion Steady progress has been made in cardiopulmonary bypass in the decades since it was first conceived of by Gibbon. Despite the constant evolution of cardiopulmonary bypass techniques and attempts to minimize their complications, it is still essential that clinicians respect the particularities of each patient's physiological function.

  7. LMA Supreme for neonatal resuscitation: study protocol for a randomized controlled trial

    PubMed Central

    2014-01-01

    Background The most important action in the resuscitation of a newborn in the delivery room is to establish effective assisted ventilation. The face mask and endotracheal tube are the devices used to achieve this goal. Laryngeal mask airways that fit over the laryngeal inlet have been shown to be effective for ventilating newborns at birth and should be considered as an alternative to facemask ventilation or endotracheal intubation among newborns weighing >2,000 g or delivered ≥34 weeks’ gestation. A recent systematic review and meta-analysis of supraglottic airways in neonatal resuscitation reported the results of four randomized controlled trials (RCTs) stating that fewer infants in the group using laryngeal mask airways required endotracheal intubation (1.5%) compared to the group using face masks (12.0%). However, there were methodological concerns over all the RCTs including the fact that the majority of the operators in the trials were anesthesiologists. Our hypothesis is based on the assumption that ventilating newborns needing positive pressure ventilation with a laryngeal mask airway will be more effective than ventilating with a face mask in a setting where neonatal resuscitation is performed by midwives, nurses, and pediatricians. The primary aim of this study will be to assess the effectiveness of the laryngeal mask airway over the face mask in preventing the need for endotracheal intubation. Methods/design This will be an open, prospective, randomized, single center, clinical trial. In this study, 142 newborns weighing >1,500 g or delivered ≥34 weeks gestation needing positive pressure ventilation at birth will be randomized to be ventilated with a laryngeal mask airway (LMA SupremeTM, LMA Company, UK - intervention group) or with a face mask (control group). Primary outcome: Proportion of newborns needing endotracheal intubation. Secondary outcomes: Apgar score at 5 minutes, time to first breath, onset of the first cry, duration of

    Investigations of compressive frequency, duty cycle, or waveform during CPR are typically rooted in animal research or computer simulations. Our goal was to generate a mechanical model incorporating alternate stiffness settings and an integrated blood flow system, enabling defined, reproducible comparisons of CPR efficacy. Based on thoracic stiffness data measured in human cadavers, such a model was constructed using valve-controlled pneumatic pistons and an artificial heart. This model offers two realistic levels of chest elasticity, with a blood flow apparatus that reflects compressive depth and waveform changes. We conducted CPR at opposing levels of physiologic stiffness, using a LUCAS device, a motor-driven plunger, and a group of volunteers. In high-stiffness mode, blood flow generated by volunteers was significantly less after just 2min of CPR, whereas flow generated by LUCAS device was superior by comparison. Optimal blood flow was obtained via motor-driven plunger, with trapezoidal waveform.

  11. Resuscitation and coagulation in the severely injured trauma patient

    PubMed Central

    Midwinter, Mark J.; Woolley, Tom

    2011-01-01

    Developments in the resuscitation of the severely injured trauma patient in the last decade have been through the increased understanding of the early pathophysiological consequences of injury together with some observations and experiences of recent casualties of conflict. In particular, the recognition of early derangements of haemostasis with hypocoagulopathy being associated with increased mortality and morbidity and the prime importance of tissue hypoperfusion as a central driver to this process in this population of patients has led to new resuscitation strategies. These strategies have focused on haemostatic resuscitation and the development of the ideas of damage control resuscitation and damage control surgery continuum. This in turn has led to a requirement to be able to more closely monitor the physiological status, of major trauma patients, including their coagulation status, and react in an anticipatory fashion.

  12. To hold her hand: family presence during patient resuscitation.

    PubMed

    Atwood, Denise A

    2008-01-01

    Family presence at the bedside during resuscitation is an important component of the patient's care. Many families report feeling that their presence at such a time is helpful to both them and the patient. Some studies suggest that family presence may reduce the chance of legal action regarding the patient's outcome because it decreases the mystery surrounding the level of effort undertaken to save the patient's life. However, many facilities are reluctant to allow family presence during resuscitation typically because of the belief that family presence will somehow disrupt the providers' ability to conduct the resuscitation. This article explores the background behind this issue and the studies done to date on family presence and makes suggestions for adopting policies allowing family presence during resuscitation.

  13. Assessing Exercise Limitation Using Cardiopulmonary Exercise Testing

    PubMed Central

    Stickland, Michael K.; Butcher, Scott J.; Marciniuk, Darcy D.; Bhutani, Mohit

    2012-01-01

    The cardiopulmonary exercise test (CPET) is an important physiological investigation that can aid clinicians in their evaluation of exercise intolerance and dyspnea. Maximal oxygen consumption (V˙O2max) is the gold-standard measure of aerobic fitness and is determined by the variables that define oxygen delivery in the Fick equation (V˙O2 = cardiac output × arterial-venous O2 content difference). In healthy subjects, of the variables involved in oxygen delivery, it is the limitations of the cardiovascular system that are most responsible for limiting exercise, as ventilation and gas exchange are sufficient to maintain arterial O2 content up to peak exercise. Patients with lung disease can develop a pulmonary limitation to exercise which can contribute to exercise intolerance and dyspnea. In these patients, ventilation may be insufficient for metabolic demand, as demonstrated by an inadequate breathing reserve, expiratory flow limitation, dynamic hyperinflation, and/or retention of arterial CO2. Lung disease patients can also develop gas exchange impairments with exercise as demonstrated by an increased alveolar-to-arterial O2 pressure difference. CPET testing data, when combined with other clinical/investigation studies, can provide the clinician with an objective method to evaluate cardiopulmonary physiology and determination of exercise intolerance.

    2014-01-01

    Background Umbilical cord milking (UCM) improves blood pressure and urine output, and decreases the need for transfusions in comparison to immediate cord clamping (ICC). The immediate effect of UCM in the first few minutes of life and the impact on neonatal resuscitation has not been described. Methods Women admitted to a tertiary care center and delivering before 32 weeks gestation were randomized to receive UCM or ICC. A blinded analysis of physiologic data collected on the newborns in the delivery room was performed using a data acquisition system. Heart rate (HR), SpO2, mean airway pressure (MAP), and FiO2 in the delivery room were compared between infants receiving UCM and infants with ICC. Results 41 of 60 neonates who were enrolled and randomized had data from analog tracings at birth. 20 of these infants received UCM and 21 had ICC. Infants receiving UCM had higher heart rates and higher SpO2 over the first 5 minutes of life, were exposed to less FiO2 over the first 10 minutes of life than infants with ICC. Conclusions UCM when compared to ICC had decreased need for support immediately following delivery, and in situations where resuscitation interventions were needed immediately, UCM has the advantage of being completed in a very short time to improve stability following delivery.

    We examined the relationship of changes in partial pressure of carbon dioxide on cerebral blood flow responsiveness in 20 pediatric patients undergoing hypothermic cardiopulmonary bypass. Cerebral blood flow was measured during steady-state hypothermic cardiopulmonary bypass with the use of xenon 133 clearance methodology at two different arterial carbon dioxide tensions. During these measurements there was no significant change in mean arterial pressure, nasopharyngeal temperature, pump flow rate, or hematocrit value. Cerebral blood flow was found to be significantly greater at higher arterial carbon dioxide tensions (p less than 0.01), so that for every millimeter of mercury rise in arterial carbon dioxide tension there was a 1.2 ml.100 gm-1.min-1 increase in cerebral blood flow. Two factors, deep hypothermia (18 degrees to 22 degrees C) and reduced age (less than 1 year), diminished the effect carbon dioxide had on cerebral blood flow responsiveness but did not eliminate it. We conclude that cerebral blood flow remains responsive to changes in arterial carbon dioxide tension during hypothermic cardiopulmonary bypass in infants and children; that is, increasing arterial carbon dioxide tension will independently increase cerebral blood flow.

  18. What people with Down Syndrome can teach us about cardiopulmonary disease.

    PubMed

    Colvin, Kelley L; Yeager, Michael E

    2017-01-01

    Down syndrome is the most common chromosomal abnormality among live-born infants. Through full or partial trisomy of chromosome 21, Down syndrome is associated with cognitive impairment, congenital malformations (particularly cardiovascular) and dysmorphic features. Immune disturbances in Down syndrome account for an enormous disease burden ranging from quality-of-life issues (autoimmune alopecia) to more serious health issues (autoimmune thyroiditis) and life-threatening issues (leukaemia, respiratory tract infections and pulmonary hypertension). Cardiovascular and pulmonary diseases account for ∼75% of the mortality seen in persons with Down syndrome. This review summarises the cardiovascular, respiratory and immune challenges faced by individuals with Down syndrome, and the genetic underpinnings of their pathobiology. We strongly advocate increased comparative studies of cardiopulmonary disease in persons with and without Down syndrome, as we believe these will lead to new strategies to prevent and treat diseases affecting millions of people worldwide.

    This study describes a hand-held, battery-powered, programmable instrument (Calculator Model SR-52) that can be taken directly into the operating room by cardiopulmonary perfusionists. Three programs are described in detail: 1) Cardiopulmonary perfusion parameters and estimated blood volume; 2) blood gas parameters and saturations, with temperature corrections; and 3) cardiopulmonary oxygen transfer and oxygenator efficiency. This inexpensive calculator allows perfusion personnel to manipulate easily-derived data into values which heretofore have required elaborate nomograms or special slide rules-or were not available within a reasonable computational time.

  20. Transient Diabetes Insipidus Following Cardiopulmonary Bypass.

    PubMed

    Ekim, Meral; Ekim, Hasan; Yilmaz, Yunus Keser; Bolat, Ali

    2015-04-01

    Diabetes insipidus (DI) results from inadequate output of Antidiuretic Hormone (ADH) from the pituitary gland (central DI) or the inability of the kidney tubules to respond to ADH (nephrogenic DI). ADH is an octapeptide produced in the supraoptic and paraventricular nuclei of the hypothalamus and stored in the posterior lobe of the pituitary gland. Cardiopulmonary Bypass (CPB) has been shown to cause a six-fold increased circulating ADH levels 12 hours after surgery. However, in some cases, ADH release may be transiently suppressed due to cardioplegia (cardiac standstill) or CPB leading to DI. We present the postoperative course of a 60-year-old man who developed transient DI after CPB. He was successfully treated by applying nasal desmopressin therapy. Relevant biochemical parameters should be monitored closely in patients who produce excessive urine after open heart surgery.

  1. Cardiopulmonary Exercise Test in Hypertrophic Cardiomyopathy.

    PubMed

    Magri, Damiano; Santolamazza, Caterina

    2017-04-04

    Understanding the functional limitation in hypertrophic cardiomyopathy, the most common inherited heart disease, is challenging. Beside the occurrence of disease-related complications, several factors are potential determinants of exercise limitation, including left ventricular hypertrophy, myocardial fiber disarray, left ventricular outflow tract obstruction, microvascular ischemia, and interstitial fibrosis. Furthermore, drugs commonly used in the daily management of these patients may interfere with exercise capacity, especially those with a negative chronotropic effect. Cardiopulmonary exercise testing can safely and objectively evaluate the functional capacity of these patients and help the physician in understanding the mechanisms that underlie this limitation. Features that reduce exercise capacity may predict progression to heart failure in these patients and even the risk of sudden cardiac death.

  2. Miniaturized cardiopulmonary bypass: the Hammersmith technique

    PubMed Central

    2013-01-01

    Background Conventional Cardiopulmonary Bypass (cCPB) is a trigger of systemic inflammatory reactions, hemodilution, coagulopathy, and organ failure. Miniaturised Cardiopulmonary Bypass (mCPB) has the potential to reduce these deleterious effects. Here, we describe our standardised ‘Hammersmith’ mCPB technique, used in all types of adult cardiac operations including major aortic surgery. Methods The use of mCPB remains limited by the diversity of technologies which range from extremely complex, micro systems to ones very similar to cCPB. Our approach is designed around the principle of balancing the benefits of miniaturisation; reducing foreign surface area while maintaining patient safety. Results From January 2010 to March 2011, a single surgeon performed 184 consecutive operations (Euro score Logistic 8.4+/-9.9): 61 aortic valve replacements, 78 CABGs, 25 aortic valve replacement and CABG and 17 other procedures (major aortic surgery, re-do operations or double/triple valve replacements). Our clinical experience suggests that: i. Venous drainage is optimally maintained using kinetic energy. ii. Venous collapse pressure depends on the patient’s anatomy and cannula size, but most importantly on the negative pressure generated by venous drainage. iii. The patient-prime interaction is optimised with antegrade and retrograde autologous priming, which mixes the blood and prime away from the tissues and results in a reduced oncotic destabilization. iv. mCPB is a safe and reproducible technique Conclusion The Hammersmith mCPB is a “next generation” system which uses standard commercially available components. It aims to maintain safety margin and the benefit of miniaturised system whilst reducing the human factor demands. PMID:23731623

    PubMed

    Wang, D; Xiang, L; Luo, J

    1996-12-01

    The ideal colloid osmotic pressure is beneficial to decrease the fluid accumulated in the pulmonary and other tissue during cardiopulmonary bypass. Schupbach reported the proper colloidosmotic pressure for cardiopulmonary bypass was 2.1 kPa (16 mmHg). Colloid osmotic pressures of blood and priming fluid during cardiopulmonary bypass were measured in 28 patients with heart disease by using colloid osmotic pressure detection apparatus. The value of colloid osmotic pressure suitable for the designed standard was apparently different among the Gelofusine group and other groups. P value was 0.005. Priming fluid for cardiopulmonary bypass needs to satisfy the quality and the quantity of colloid osmotic pressure. Using Albumin isn't economical. Whole blood and plazma are not suitable for increasing colloid osmotic pressure. Hydroxyethyl starch or Gelofusine is best choice in priming to get designed standard of colloid osmotic pressure. The ratio of hydroxyethyl starch or Gelofusine in priming fluid should beyond 1/2.

  6. Resuscitation following injury: an end or a means?

    PubMed

    Civil, I D

    1993-12-01

    It is known that a successful outcome after injury requires haemostasis and replacement of intra- and extracellular fluid losses. In situations of controlled haemorrhage rapid replacement of these fluid losses is likely to be associated with the least morbidity. When considering uncontrolled haemorrhage, however, there is good evidence that effective resuscitative devices and strategies have proven to be associated with a worse outcome when used initially than when their use follows surgical control of bleeding. Despite newer developments in resuscitative technique, surgeons must continue to be involved in the early management of the severely injured so that they are in the best position to employ their skills and provide surgical haemostasis when and where it is required. The 'end' therefore in resuscitation of the injured is a normovolaemic, normotensive patient who is physiologically stable and able to have definitive management of his/her anatomic injuries. The 'means' are good prehospital care, accurate initial assessment and resuscitation that employs temporary and definitive haemostasis combined with adequate volumes of appropriately chosen and delivered resuscitation fluid.

  7. Microcirculatory and mitochondrial hypoxia in sepsis, shock, and resuscitation.

    PubMed

    Ince, Can; Mik, Egbert G

    2016-01-15

    After shock, persistent oxygen extraction deficit despite the apparent adequate recovery of systemic hemodynamic and oxygen-derived variables has been a source of uncertainty and controversy. Dysfunction of oxygen transport pathways during intensive care underlies the sequelae that lead to organ failure, and the limitations of techniques used to measure tissue oxygenation in vivo have contributed to the lack of progress in this area. Novel techniques have provided detailed quantitative insight into the determinants of microcirculatory and mitochondrial oxygenation. These techniques, which are based on the oxygen-dependent quenching of phosphorescence or delayed luminescence are briefly reviewed. The application of these techniques to animal models of shock and resuscitation revealed the heterogeneous nature of oxygen distributions and the alterations in oxygen distribution in the microcirculation and in mitochondria. These studies identified functional shunting in the microcirculation as an underlying cause of oxygen extraction deficit observed in states of shock and resuscitation. The translation of these concepts to the bedside has been enabled by our development and clinical introduction of hand-held microscopy. This tool facilitates the direct observation of the microcirculation and its alterations at the bedside under the conditions of shock and resuscitation. Studies identified loss of coherence between the macrocirculation and the microcirculation, in which resuscitation successfully restored systemic circulation but did not alleviate microcirculatory perfusion alterations. Various mechanisms responsible for these alterations underlie the loss of hemodynamic coherence during unsuccessful resuscitation procedures. Therapeutic resolution of persistent heterogeneous microcirculatory alterations is expected to improve outcomes in critically ill patients.

  8. [Simulation of neonatal resuscitation in the delivery room].

    PubMed

    Pfister, R E; Savoldelli, G L

    2011-07-01

    Neonatal resuscitation is one of the most cost-effective medical interventions, most often an emergency procedure involving a multidisciplinary team in the delivery room: doctors, nurses, midwives, obstetricians, anesthetists and other theatre staff. The success of resuscitation depends not only on individual competence but also on efficient teamwork between healthcare professionals in the delivery room; failure often results from the weakest link. Initiation of basic resuscitation procedures must be rapid and effective. Simple procedures must therefore be known by a large number of healthcare professionals, in fact all those potentially present at a delivery. Many complex neonatal diseases on the other hand are too infrequent for all to acquire sufficient personal experience. In addition, synchronization between the interventions of the different members in a perinatal team is complex. It is therefore necessary to train both individuals and teams to better manage perinatal crisis situations. The educational approach should remain multimodal, combining teaching of technical and non-techniques skills. Simulation of resuscitation scenarios can mimic emergency situations without any risk to the patient. It can be used for teaching and/or evaluation of the effectiveness of procedures and collaboration between actors. For maximum performance in complex pathologies, multidisciplinary teaching sessions are necessary. Simulation techniques adapted to neonatal resuscitation in the delivery room appear of great educational interest and proof of their efficiency gradually appears in literature.

    Nutritional quality during the first weeks of life can influence health during both infancy and adulthood. Exclusive long-term breast feeding is strongly recommended, particularly for infants at risk of allergy. It protects against gastrointestinal and respiratory infections, and has been shown to enhance cognitive and intellectual development. Breast-feeding is also associated with a lower risk of obesity and type 1 diabetes in infants and of cardiovascular disease in adults. Breast-feeding is rarely contraindicated. Multiple European and French guidelines and regulations govern the composition of infant formulas, which may be given during the first year of life when breast-feeding is unavailable. Hypoallergenic and soy-based formulas are not recommended for healthy infants.

    Introduction Non-pediatric trainees working in pediatrics in the UK are expected to attend newborn deliveries and provide initial newborn life support if needed. In Swindon, new junior doctors receive a 90-minute teaching session at the start of their pediatrics rotation, but the content has not previously been standardized, and it may be several weeks before a doctor attends a newborn delivery. Thus, the confidence and competence in newborn resuscitation of doctors attending deliveries can vastly vary. Methods A standardized teaching package was developed as part of the pediatrics induction program. This includes an interactive lecture on the physiology of the newborn, skills stations, and mini-simulations to consolidate skills. This is accompanied by a program of regular neonatal mini-simulations as part of the departmental morning teaching program. These sessions allow junior doctors to practice their skills in a safe, simulated environment and reinforce the newborn life support pathway. Results Qualitative and quantitative feedback was sought following delivery of the induction training session. Junior doctors were asked to rate their confidence before and after the induction session using Likert scales from 1 (least confident) to 5 (most confident). Median confidence in attending term deliveries increased from 2 (range 1 - 4) to 4 (2 - 5), P=0.008. There was evidence that confidence was maintained at one month following induction. Conclusions A simulation program has been successful at improving confidence among junior doctors in attending newborn deliveries. This has the potential to improve patient care and trainees’ experiences of their pediatrics placement. PMID:27774358

    We report a case of botulism in a 40 day old infant. The patient presented a descending flaccid paralysis requiring mechanical ventilation for 12 days. She is the first European patient treated with Human Botulism Immune Globulin. A few weeks later a second case of infant botulism was detected in our geographical region in Southern Spain. We emphasise the importance of an early diagnosis and treatment with Human Botulism Immune Globulin to decrease morbidity.

    The pediatric sepsis syndrome remains a common cause of morbidity, mortality, and health care utilization costs worldwide. The initial resuscitation and management of pediatric sepsis is focused on 1) rapid recognition of abnormal tissue perfusion and restoration of adequate cardiovascular function, 2) eradication of the inciting invasive infection, including prompt administration of empiric broad-spectrum antimicrobial medications, and 3) supportive care of organ system dysfunction. Efforts to improve early and aggressive initial resuscitation and ongoing management strategies have improved outcomes in pediatric severe sepsis and septic shock, though many questions still remain as to the optimal therapeutic strategies for many patients. In this article, we will briefly review the definitions, epidemiology, clinical manifestations, and pathophysiology of sepsis and provide an extensive overview of both current and novel therapeutic strategies used to resuscitate and manage pediatric patients with severe sepsis and septic shock.

    PubMed Central

    2009-01-01

    Background Initiation of ventilation using high tidal volumes in preterm lambs causes lung injury and inflammation. Antenatal corticosteroids mature the lungs of preterm infants and postnatal corticosteroids are used to treat bronchopulmonary dysplasia. Objective To test if antenatal or postnatal corticosteroids would decrease resuscitation induced lung injury. Methods 129 d gestational age lambs (n = 5-8/gp; term = 150 d) were operatively delivered and ventilated after exposure to either 1) no medication, 2) antenatal maternal IM Betamethasone 0.5 mg/kg 24 h prior to delivery, 3) 0.5 mg/kg Dexamethasone IV at delivery or 4) Cortisol 2 mg/kg IV at delivery. Lambs then were ventilated with no PEEP and escalating tidal volumes (VT) to 15 mL/kg for 15 min and then given surfactant. The lambs were ventilated with VT 8 mL/kg and PEEP 5 cmH20 for 2 h 45 min. Results High VT ventilation caused a deterioration of lung physiology, lung inflammation and injury. Antenatal betamethasone improved ventilation, decreased inflammatory cytokine mRNA expression and alveolar protein leak, but did not prevent neutrophil influx. Postnatal dexamethasone decreased pro-inflammatory cytokine expression, but had no beneficial effect on ventilation, and postnatal cortisol had no effect. Ventilation increased liver serum amyloid mRNA expression, which was unaffected by corticosteroids. Conclusions Antenatal betamethasone decreased lung injury without decreasing lung inflammatory cells or systemic acute phase responses. Postnatal dexamethasone or cortisol, at the doses tested, did not have important effects on lung function or injury, suggesting that corticosteroids given at birth will not decrease resuscitation mediated injury.

    The aim of this discussion is to raise awareness of the negative aspects of witnessed resuscitation. The historical precedents associated with the introduction of the concept are outlined. The disadvantages of introducing witnessed resuscitation are delineated. These include issues of human dignity, personal privacy and the provision of adequately trained staff to help relatives cope with the emotional trauma the experience of being a witness may invoke. The paper concludes by calling for more widespread debate and research into the efficacy of introducing such policies into practice.

    Objective This study was designed to evaluate the cardiotoxicity of a QX-314 analog (QX-OH) and a mixture of QX-OH and levobupivacaine (LL-1) and to compare the ability to resuscitate rats after asystole induced by levobupivacaine (Levo-BUP), QX-314, QX-OH, and LL-1. Methods First, we used the “up-and-down” method to determine median dose resulting in appearance of cardiotoxicity (CD50C) and asystole (CD50A) of Levo-BUP, QX-314, QX-OH, and LL-1 in rats. Safety index (SI; ratio of CD50C compared with 2-fold median effective dose needed to produce sensory blockade) of the 4 drugs was calculated. Isobolograms were used for drug interaction analysis. Second, rats received 1.2-fold CD50A in the 4 groups. When asystole occurred, standard cardiopulmonary resuscitation was started and continued for 30 min or until return of spontaneous circulation (ROSC) with native rate–pressure product ≥30% baseline for 5 min. Results Ranking of CD50C was Levo-BUP < QX-314 ≈ QX-OH. Ranking of CD50A was Levo-BUP < QX-314 < QX-OH. However, the SI of Levo-BUP was significantly higher than that of QX-314 (10.60 vs. 1.20) or QX-OH (10.60 vs. 1.44). The SI of LL-1 was similar to that of Levo-BUP. Nonsynergistic interaction was observed for cardiac effects between QX-OH and Levo-BUP. ROSC was attained initially by 8 of 8 rats in the Levo-BUP group, 3 of 8 in the QX-314 group, 6 of 8 in the QX-OH group, and 8 of 8 in the LL-1 group. Sustained recovery was achieved in the Levo-BUP group but not in the other groups. Conclusion Levo-BUP and LL-1 are safer than QX-314 or QX-OH. Cardiac effects between QX-OH and Levo-BUP were nonsynergistic. Initial successful resuscitation could be achieved in the QX-OH- and LL-1-induced asystole, but advanced life support might be needed.

    Cardiopulmonary exercise test (CPET) has been gaining importance as a method of functional assessment in Brazil and worldwide. In its most frequent applications, CPET consists in applying a gradually increasing intensity exercise until exhaustion or until the appearance of limiting symptoms and/or signs. The following parameters are measured: ventilation; oxygen consumption (VO2); carbon dioxide production (VCO2); and the other variables of conventional exercise testing. In addition, in specific situations, pulse oximetry and flow-volume loops during and after exertion are measured. The CPET provides joint data analysis that allows complete assessment of the cardiovascular, respiratory, muscular and metabolic systems during exertion, being considered gold standard for cardiorespiratory functional assessment.1-6 The CPET allows defining mechanisms related to low functional capacity that can cause symptoms, such as dyspnea, and correlate them with changes in the cardiovascular, pulmonary and skeletal muscle systems. Furthermore, it can be used to provide the prognostic assessment of patients with heart or lung diseases, and in the preoperative period, in addition to aiding in a more careful exercise prescription to healthy subjects, athletes and patients with heart or lung diseases. Similarly to CPET clinical use, its research also increases, with the publication of several scientific contributions from Brazilian researchers in high-impact journals. Therefore, this study aimed at providing a comprehensive review on the applicability of CPET to different clinical situations, in addition to serving as a practical guide for the interpretation of that test.

    In patients affected by chronic obstructive pulmonary disease (COPD), cardiopulmonary response to exercise was never related to the severity of emphysema (E) measured by high resolution computed tomography (HRCT). Sixteen patients (age=65±8 yrs; FEV(1)=54±18%pred; RV=160±28%pred) with moderate to severe E (quantified by lung HRCT as % voxels <-910 HU) were exercised on a cycle-ergometer to exhaustion. Oxygen uptake (V˙(O2)), carbon dioxide output (V˙(CO2)), ventilation (V˙(E)), tidal volume (V(T)), and end-tidal P(CO2) (PET(CO2)) derived variables were measured breath-by-breath. The % of E correlated with: (1) the ratio V(Tpeak) (r=0.74; p=0.001); (2) the V˙(E)/V˙(CO2) slope (r=-0.77; p=0.0004); (3) PET(CO2) values at peak exercise (r=0.80; p=0.0001). Also, the %E was strongly predicted by the following exercise equation: %E(EST) = 58.1 + 11.9 × ΔV˙(E)/V˙(CO2) (r=0.94; p<0.0001). A V(Tpeak)/FEV1 ratio>1 is typically observed in severe E patients; furthermore, the V˙(E)/V˙(CO2) slope and the PET(CO2peak) values decrease and increase respectively as more as the emphysema is severe.

    Hantavirus (Bunyaviridae) cardiopulmonary syndrome (HCPS) is an emerging health problem in South America due to urban growth and to the expansion of agriculture and cattle-raising areas into ecosystems containing most of the species of Sigmodontinae rodents that act as hantavirus reservoirs. About 4000 HCPS cases have been reported in South America up to 2013, associated with the following hantaviruses: Andes, Anajatuba, Araraquara (ARQV), Paranoá, Bermejo, Castelo dos Sonhos, Juquitiba, Araucária, Laguna Negra, Lechiguanas, Maripa, Oran, Rio Mamore and Tunari. The transmission of hantavirus to man occurs by contact with or through aerosols of excreta and secretions of infected rodents. Person-to-person transmission of hantavirus has also been reported in Argentina and Chile. HCPS courses with a capillary leaking syndrome produced by the hantavirus infecting lung endothelial cells and mostly with a severe inflammatory process associated with a cytokine storm. HCPS starts as a dengue-like acute febrile illness but after about 3 days progresses to respiratory failure and cardiogenic shock, leading to a high fatality rate that reaches 50% for patients infected with ARQV.

    Dilemmas about resuscitation and life-prolonging treatment for severely compromised infants have become increasingly complex as skills in neonatal care have developed. Quality of life and resource issues necessarily influence management. Our Institute of Medical Ethics working party, on whose behalf this paper is written, recognises that the ultimate responsibility for the final decision rests with the doctor in clinical charge of the infant. However, we advocate a team approach to decision-making, emphasising the important role of parents and nurses in the process. Assessing the relative burdens and benefits can be troubling, but doctors and parents need to retain a measure of discretion; legislation which would determine action in all cases is inappropriate. Caution should be exercised in involving committees in decision-making and, where they exist, their remit should remain to advise rather than to decide. Support for families who bear the consequences of their decisions is often inadequate, and facilitating access to such services is part of the wider responsibilities of the intensive care team. The authors believe that allowing death by withholding or withdrawing treatment is legitimate, where those closely involved in the care of the infant together deem the burdens to be unacceptable without compensating benefits for the infant. As part of the process accurate and careful recording is essential.

    Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD) newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB), has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN) measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P < 0.01) during CPB and at the end of the surgical procedure. Moreover, ADN showed a flat pattern and no significant differences (P > 0.05) have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Infants are vulnerable: their growth and their development depend largely on their nutritional status. It is important to propose for them an optimal food. The human milk is unquestionably the best choice for the infant. When breastfeeding is not possible, the choice of the milk is made among hundreds of formulas for infants. They are regulated by a European directive. The healthcare professionals have to recommend as often as possible an infant formula: low protein content, predominance of whey proteins, enrichment with long chain fatty acids, lactose, addition of pre- or probiotics. The formulas for specific indications will be recommended in case of particular situations after verification that the complaints (constipation, regurgitations, stomach pains) cannot be corrected by simple dietary measures (increasing of the intakes of meals with a concomitant reduction of the volume of the meals). The food diversification is recommended between 17 and 26 weeks according to the neuromuscular capacities of the infant. These meals must be presented with a spoon to assure a sufficient nutritional intake. In Belgium, the use is to begin with fruits. One should avoid adding biscuits or sugar. The meal of vegetables will be introduced a little later. It should consist of starchy foods, vegetables with some fat to which the meat will be added. Numerous foods (biscuits, croissants and similar products, chips) should never be part of the ordinary menu, but should be reserved for particular occasions. The education of the children should begin from this age on.

    Handoffs for neonatal resuscitation involve communicating critical delivery information (CDI). The authors sought to achieve ≥95% communication of CDI during resuscitation team requests. CDI included name of caller, urgency of request, location of delivery, gestation of fetus, status of amniotic fluid, and indication for presence of the resuscitation team. Three interventions were implemented: verbal scripted handoff, Spök text messaging, and Engage text messaging. Percentages of CDI communications were analyzed using statistical process control. Following implementation of Engage, the communication of all CDI, except for indication, was ≥95%; communication of indication occurred 93% of the time. Control limits for most CDI were narrower with Engage, indicating greater reliability of communication compared to the verbal handoff and Spök. Delayed resuscitation team arrival, a countermeasure, was not higher with text messaging compared to verbal handoff (P = 1.00). Text messaging improved communication during high-risk deliveries, and it may represent an effective tool for other delivery centers.

    Currently, the aim of the resuscitation of burn patients is to maintain end-organ perfusion with fluid intake as minimal as possible. To avoid excess intake, we can improve the estimation using computer methods. Parkland and Brooke are the commonly used formulas, and recently, a new, an easy formula is been used, i.e. the 'Rule of TEN'. Fluid resuscitation should be titrated to maintain the urine output of approximately 30-35 mL/h for an average-sized adult. The most commonly used fluids are crystalloid, but the phenomenon of creep flow has renewed interest in albumin. In severely burn patients, monitoring with transpulmonary thermodilution together with lactate, ScvO2 and intraabdominal pressures is a good option. Nurse-driven protocols or computer-based resuscitation algorithms reduce the dependence on clinical decision making and decrease fluid resuscitation intake. High-dose vitamin C, propranolol, the avoidance of excessive use of morphine and mechanical ventilation are other useful resources.

This guide is expected to be adapted by local groups or committees on resuscitation, according to their own circumstances. The objective of this review is to analyse the main changes, to discuss several of the controversies that have appeared since 2010, and contrasting with other national and international organisations, such as European Resuscitation Council (ERC), American Heart Association (AHA), or the Australian-New Zealand Committee on Resuscitation (ANZCOR). Thus, the Neonatal Resuscitation Group of the Spanish Society of Neonatology (GRN-SENeo) aims to give clear answers to many of the questions when different options are available, generating the forthcoming recommendations of our country to support the transition and/or resuscitation of a newborn after birth, safely and effectively.

    Smartphones are ubiquitous now, but it is still unclear what physiological functions they can monitor at clinical quality. Pulmonary function is a standard measure of health status for cardiopulmonary patients. We have shown that predictive models can accurately classify cardiopulmonary conditions from healthy status, as well as different severity levels within cardiopulmonary disease, the GOLD stages. Here we propose several universal models to monitor cardiopulmonary conditions, including DPClass, a novel learning approach we designed. We carefully prepare motion dataset covering status from GOLD 0 (healthy), GOLD 1 (mild), GOLD 2 (moderate), all the way to GOLD 3 (severe). Sixty-six subjects participate in this study. After de-identification, their walking data are applied to train the predictive models. The RBF-SVM model yields the highest accuracy while the DPClass model provides better interpretation of the model mechanisms. We not only provide promising solutions to monitor health status by simply carrying a smartphone, but also demonstrate how demographics influences predictive models of cardiopulmonary disease.

    PubMed

    Fadel, Paul J; Raven, Peter B

    2012-01-01

    After considerable debate and key experimental evidence, the importance of the arterial baroreflex in contributing to and maintaining the appropriate neural cardiovascular adjustments to exercise is now well accepted. Indeed, the arterial baroreflex resets during exercise in an intensity-dependent manner to continue to regulate blood pressure as effectively as at rest. Studies have indicated that the exercise resetting of the arterial baroreflex is mediated by both the feedforward mechanism of central command and the feedback mechanism associated with skeletal muscle afferents (the exercise pressor reflex). Another perhaps less appreciated neural mechanism involved in evoking and maintaining neural cardiovascular responses to exercise is the cardiopulmonary baroreflex. The limited information available regarding the cardiopulmonary baroreflex during exercise provides evidence for a role in mediating sympathetic nerve activity and blood pressure responses. In addition, recent investigations have demonstrated an interaction between cardiopulmonary baroreceptors and the arterial baroreflex during dynamic exercise, which contributes to the magnitude of exercise-induced increases in blood pressure as well as the resetting of the arterial baroreflex. Furthermore, neural inputs from the cardiopulmonary baroreceptors appear to play an important role in establishing the operating point of the arterial baroreflex. This symposium review highlights recent studies in these important areas indicating that the interactions of four neural mechanisms (central command, the exercise pressor reflex, the arterial baroreflex and cardiopulmonary baroreflex) are integral in mediating the neural cardiovascular adjustments to exercise.

    Background Many neonatal deaths can be prevented globally through effective resuscitation. South Africa (SA) committed towards attaining the Millennium Development Goal 4 (MDG4) set by the World Health Organization (WHO). However, SA’s district hospitals have the highest early neonatal mortality rates. Modifiable and avoidable causes associated with patient-related, administrative and health care provider factors contribute to neonatal mortality. A quality improvement initiative in neonatal resuscitation could contribute towards decreasing neonatal mortality, thereby contributing towards the attainment of the MDG4. Aim The aim of this study was, (1) to explore and describe the existing situation regarding neonatal resuscitation in a district hospital, (2) to develop strategies to sustain a neonatal resuscitation quality improvement initiative and (3) to decrease neonatal mortality. Changes that occurred and the sustainability of strategies were evaluated. Setting A maternity section of a district hospital in South Africa. Methods The National Health Service (NHS) Sustainability Model formed the theoretical framework for the study. The Problem Resolving Action Research model was applied and the study was conducted in three cycles. Purposive sampling was used for the quantitative and qualitative aspects of data collection. Data was analysed accordingly. Results The findings indicated that the strategies formulated and implemented to address factors related to neonatal resuscitation (training, equipment and stock, staff shortages, staff attitude, neonatal transport and protocols) had probable sustainability and contributed towards a reduction in neonatal mortality in the setting. Conclusion These strategies had the probability of sustainability and could potentially improve neonatal outcomes and reduce neonatal mortality to contribute toward South Africa’s’ drive to attain the MDG4.

    Abstract: Neurologic injury after cardiac surgery is principally associated with emboli. Although much work has focused on surgical sources of emboli, less attention has been focused on emboli associated with the heart–lung machine. We tested whether emboli are associated with discrete processes during cardiopulmonary bypass (CPB). One hundred patients undergoing cardiothoracic surgery were enrolled between April 2008 and May 2011 at a single medical center. During each surgical procedure, emboli were counted in three CPB locations: the venous side (Channel 1), before the arterial line filter (Channel 2), and after the arterial line filter (Channel 3). We used prespecified event markers to identify perfusionist interventions. Identical circuits were used on all patients. Of the 100 patients enrolled, 62 underwent isolated coronary artery bypass grafting (CABG), 17 underwent isolated valve operations, and 21 underwent CABG plus valve. Median counts across Channels 1, 2, and 3 were 69,853, 3,017, and 1,251, respectively. The greatest contributor to emboli in Channels 1, 2, and 3, respectively, were achieving the calculated CPB flow, opening of the electronic arterial line clamp, and introducing a hemofilter. The circuit technology was efficient in reducing total emboli counts from Channels 1–2 irrespective of the size of the emboli. Nearly 71% of all emboli 30–100 mm in size were removed from the circuit between Channels 2 and 3. No significant association was found between emboli counts and S100B release. Emboli occur frequently during CPB and are predominantly associated with the initiation of bypass, operation of the electronic arterial line clamp, and the initiation of a hemofilter. Continued work to reduce the occurrence of emboli is warranted. PMID:25208432

  17. Gravity and Development of Cardiopulmonary Reflex

    Cardio-pulmonary reflex, which our cardiac activity is synchronized to the respiration by autonomic nervous system regulation, is called as "respiratory sinus arrhythmia" and commonly found in adult. The physiological function of the espiratory sinus arrhythmia is considered to maximize the gas exchange during respiration cycle. This respiration induced heart rate variability (RHRV) is only found in mammals and avian showing a remarkable postnatal development, whereas no RHRV in aquatic species such as fish or amphibian. To elucidate our hypothesis that gravity exposure may plays a key role in the postnatal development of RHRV as well as its evolutional origin in these ground animals, we have studied effects of hypergravity (2G) on the postnatal development of RHRV using rat. Pregnant Wister rats were kept in centrifugal cages system for 38 days from 6th days of pregnant mother to have neonates until 23 days old. Electrocardiograph was recorded from the neonates in 2 to 23 days old in 2G group with simultaneous control (1G) group. The RHRV analysis was performed by calculating a component of Fourier power spectral coincide with the respiration frequency. In both groups, averaged resting heart rate gradually increase from 2 to 23 days old. When comparing the heart rate between the two groups, the 2G group indicated significantly lower (240± 8 bpm) than 1G control (326±21 bpm, p¡0.001) in 2 days old, where as no significance in 23 days old. The RHRV of 2 days old neonates in both groups indicated very small magnitude but significantly lower in 2G group than 1G control (p¡0.01). The RHRV gradually increase during the first 2 weeks and then rapid increased to reached 45 fold of magnitude in 1G control, whereas 69 fold in 2G group. The results strongly suggested that the postnatal innervation from respiration to cardiovascular centers was gravity dependent.

    Brain damage due to an episode of hypoxia remains a major problem in infants causing deficit in motor and sensory function. Molecular processes regulating the dopamine receptors play a very important role in motor and cognitive functions. Disturbances in the development of the dopaminergic system lead to dyskinesia, dystonia, tics and abnormal eye movements. The present study is to understand the hypoxic damage to the dopamine content and dopamine D(1), dopamine D(2) receptors in cerebellum and the neuroprotective effect of glucose supplementation prior to the current sequence of resuscitation-oxygen and epinephrine supplementation in neonatal rats. Dopamine content in the cerebellum showed a significant decrease in hypoxic neonatal rats when compared to control. Dopamine D(1) and dopamine D(2) receptors showed a decrease in B(max) during hypoxia. The cerebellar dopamine, dopamine D(1) and dopamine D(2) receptors showed significant decrease on supplementation of 100% oxygen alone to hypoxic rats when compared to control rats. Dopamine D(1) and dopamine D(2) receptors mRNA showed significant decrease during epinephrine supplementation prior to resuscitation. These dopaminergic receptor alterations were reversed to near control by glucose supplementation. Thus our results suggest that glucose acts as a neuroprotective agent in dopaminergic receptors function. This has immense clinical significance to correct the resuscitation sequence in neonatal care.

    Hantavirus cardiopulmonary syndrome has a high mortality rate, and early connection to extracorporeal membrane oxygenation has been suggested to improve outcomes. We report the case of a patient with demonstrated Hantavirus cardiopulmonary syndrome and refractory shock who fulfilled the criteria for extracorporeal membrane oxygenation and responded successfully to high volume continuous hemofiltration. The implementation of high volume continuous hemofiltration along with protective ventilation reversed the shock within a few hours and may have prompted recovery. In patients with Hantavirus cardiopulmonary syndrome, a short course of high volume continuous hemofiltration may help differentiate patients who can be treated with conventional intensive care unit management from those who will require more complex therapies, such as extracorporeal membrane oxygenation.

    1982-01-01

    The anaesthetic management of cardiopulmonary bypass (CPB) for a patient with biopsy-proven malignant hyperthermia is reported. Specific changes in the technique used, such as venting the oxygenator before use, monitoring mixed venous PO2 and PCO2, as well as the safety of cold hyperkalaemic cardioplegia are described. Controversial aspects of malignant hyperthermia management such as the safety of calcium and catechol inotropes are discussed in relationship to the successful use of cardio-pulmonary bypass in our patient. We chose to treat left ventricular dysfunction by aggressive vasodilator (nitroglycerine) therapy. We detected no myocardial or respiratory depression secondary to dantrolene therapy either before or after operation.

  11. DC information preservation for cardiopulmonary monitor utilizing CW Doppler radar.

    PubMed

    Vergara, Alexander M; Boric-Lubecke, Olga; Lubecke, Victor M

    Direct conversion RF receivers introduce large DC offsets, reducing the dynamic range of the baseband signal. Coupled with the relatively small time varying signals in human vital sign monitoring using CW Doppler radar, extraction of cardio-pulmonary information becomes difficult. Previous DC offset compensation techniques utilizing AC coupling have proven detrimental to the performance of the system and the integrity of the low-frequency cardiopulmonary signals. A proposed system utilizing digitally controlled voltage feedback and center finding preserves the important DC information for optimal extraction of phase information in the quadrature system.

    Findings indicate a dynamical coupling between respiratory and cardiac function. However, the nature of this nonlinear interaction remains not well understood. We investigate transient patterns in the cardio-pulmonary interaction under healthy conditions by means of cross-correlation and nonlinear synchronization techniques, and we compare how these patterns change under pathologic conditions such as obstructive sleep apnea --- a periodic cessation of breathing during sleep. We find that during apnea episodes the nonlinear features of cardio-pulmonary interaction change intermittently, and can exhibit variations characterized by different time delays in the phase synchronization between breathing and heartbeat dynamics.

  13. Confirmation of correct tracheal tube placement in newborn infants.

    2013-06-01

    Tracheal intubation remains a common procedure during neonatal intensive care. Rapid confirmation of correct tube placement is important because tube malposition is associated with serious adverse outcomes. The current gold standard test to confirm tube position is a chest radiograph, however this is often delayed until after ventilation has commenced. Hence, point of care methods to confirm correct tube placement have been developed. The aim of this article is to review the available literature on tube placement in newborn infants. We reviewed books, resuscitation manuals and articles from 1830 to the present with the search terms "Infant, Newborn", "Endotracheal intubation", "Resuscitation", "Clinical signs", "Radiography", "Respiratory Function Tests", "Laryngoscopy", "Ultrasonography", and "Bronchoscopy". Various techniques have been studied to help clinicians assess tube placement. However, despite 85 years of clinical practice, the search for higher success rates and quicker intubation continues. Currently, chest radiography remains the gold standard test to confirm tube position. However, rigorous evaluation of new techniques is required to ensure the safety of newborn infants.

    Background Traumatic injury is a leading cause of morbidity and mortality in developed countries worldwide. Recent studies suggest that many deaths are preventable if injuries are recognized and treated in an expeditious manner – the so called 'golden hour' of trauma. Ultrasound revolutionized the care of the trauma patient with the introduction of the FAST (Focused Assessment with Sonography for Trauma) examination; a rapid assessment of the hemodynamically unstable patient to identify the presence of peritoneal and/or pericardial fluid. Since that time the use of ultrasound has expanded to include a rapid assessment of almost every facet of the trauma patient. As a result, ultrasound is not only viewed as a diagnostic test, but actually as an extension of the physical exam. Methods A review of the medical literature was performed and articles pertaining to ultrasound-assisted assessment of the trauma patient were obtained. The literature selected was based on the preference and clinical expertise of authors. Discussion In this review we explore the benefits and pitfalls of applying resuscitative ultrasound to every aspect of the initial assessment of the critically injured trauma patient. PMID:19660123

  16. The protective effects of high-dose ascorbic acid on myocardium against reperfusion injury during and after cardiopulmonary bypass.

    PubMed

    Dingchao, H; Zhiduan, Q; Liye, H; Xiaodong, F

    1994-10-01

    The protective effects of high-dose ascorbic acid (250 mg/kg) on the myocardium were observed in 85 patients undergoing Cardiopulmonary Bypass (CPB). The changes in serum Malonyldialdehyde (MDA). Creatine Phosphokinase (CPK), Creatine Phosphokinase isozyme (CPK-MB) and Lactic Dehydrogenase (LDH) in group B (n = 45, receiving ascorbic acid) were lower (p < 0.05) than in group A (n = 40, no ascorbic acid) during and after CPB. The MDA remained at a higher level two days postoperatively; CPK and CPK-MB, the sensitive and specific reflectors of myocardial injury, recovered very slowly in the control group (A) after the operation. The hearts in all the patients of group B resuscitated automatically intraoperatively while five cases (12.5%) needed defibrillation in group A. The cardiac index (CI) measured in ICU in group B was higher than in group A (p < 0.05). The patients needed shorter ICU and hospital stays in group B than in group A. The results indicate that ascorbic acid can act as a scavenger of free radicals to decrease the peroxidation of the lipids present in the cell membrane and remove the radicals to protect the myocardium from ischemia-reperfusion injury effectively during and after open-heart operation.

    Background. Basic life support (BLS) training with hands-on practice can improve performance during simulated cardiac arrest, although the optimal duration for BLS training is unknown. This study aimed to assess the effectiveness of various BLS training durations for acquiring cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) skills. Methods. We randomised 485 South Korean nonmedical college students into four levels of BLS training: level 1 (40 min), level 2 (80 min), level 3 (120 min), and level 4 (180 min). Before and after each level, the participants completed questionnaires regarding their willingness to perform CPR and use AEDs, and their psychomotor skills for CPR and AED use were assessed using a manikin with Skill-Reporter™ software. Results. There were no significant differences between levels 1 and 2, although levels 3 and 4 exhibited significant differences in the proportion of overall adequate chest compressions (p < 0.001) and average chest compression depth (p = 0.003). All levels exhibited a greater posttest willingness to perform CPR and use AEDs (all, p < 0.001). Conclusions. Brief BLS training provided a moderate level of skill for performing CPR and using AEDs. However, high-quality skills for CPR required longer and hands-on training, particularly hands-on training with AEDs.

    Objective The objective of the present study was to explore the resuscitative effect of small-volume resuscitation on uncontrolled hemorrhagic shock in emergency. Methods In this study, the resuscitative effects in 200 trauma patients with uncontrolled hemorrhagic shock in emergency were studied. Half of these patients were infused with hypertonic/hyperoncotic fluid (small-volume resuscitation group, n=100), whereas the rest were infused with Hespan and lactated Ringer’s solution (conventional fluid resuscitation group, n=100). The changes in hemodynamics, coagulation function, blood biochemistry, blood hematology, and the average infusion volume in both the groups were comparatively studied. Results It was found that the hemodynamics were improved in both the groups after resuscitation. Interestingly, compared with trauma patients infused with Hespan and lactated Ringer’s solution, the growth rate, range, and time duration of the mean arterial pressure of the patients in small-volume resuscitation group increased significantly, and the shock index decreased progressively; in the 60th min after the resuscitation, blood index including hemoglobin, hematocrit, red blood cells, white blood cells, and platelet declined, whereas prothrombin time and activated partial thromboplastin time were prolonged in both the groups, but these changes were less obvious in the small-volume group. In addition, the average infusion volume of patients in the small-volume group was less than that of patients in conventional fluid resuscitation group. Conclusion Featured with small infusion volume and less influence to coagulation function and homeostasis of human body, small-volume resuscitation possesses a significantly higher resuscitative effect. Therefore, trauma patients may have a better chance to maintain the hemodynamic stability and the survival rate, or recovery speed will be increased when traditional aggressive fluid resuscitation is replaced by small-volume resuscitation

    Introduction The 2010 cardiopulmonary resuscitation guidelines recommend emergency medical services (EMS) personnel consider prehospital termination-of-resuscitation (TOR) rules for out-of-hospital cardiac arrest (OHCA) following basic life support and/or advanced life support efforts in the field. However, the rate of implementation of international TOR rules is still low. Here, we aimed to develop and validate a new TOR rule for emergency department physicians to replace the international TOR rules for EMS personnel in the field. This rule aims to guide physicians in deciding whether to withhold further resuscitation attempts or terminate on-going resuscitation immediately after patient arrival. Methods We analyzed data prospectively collected in a nationwide Utstein-style Japanese database between 2005 and 2009, from 495,607 adult patients with OHCA. Patients were divided into development (n = 390,577) and validation (n = 105,030) groups. The main outcome measures were specificity, positive predictive value (PPV), and area under the receiver operating characteristic (ROC) curve for the newly developed TOR rule. Results We developed a new TOR rule that includes 3 criteria based on the results of multivariate logistic regression analysis for predicting a 1-month death after OHCA: no prehospital return of spontaneous circulation (adjusted odds ratio [OR], 25.8; 95% confidence interval [CI], 24.7–26.9), unshockable initial rhythm (adjusted OR, 2.76; 95% CI, 2.54–3.01), and unwitnessed by bystanders (adjusted OR, 2.18; 95% CI, 2.09–2.28). The specificity, PPV, and area under the ROC curve for this new TOR rule for predicting 1-month death in the validation group were 0.903 (95% CI, 0.894–0.911), 0.993 (95% CI, 0.992–0.993), and 0.874 (95% CI, 0.872–0.876), respectively. Conclusions We developed and validated a new TOR rule for emergency department physicians consisting of 3 prehospital variables (no prehospital ROSC, unshockable initial rhythm, and

    Calf blood flow was measured by venous occlusion plethysmography using a mercury in rubber strain gauge in infants with transposition of the great vessels. (TGV), and in comparable infants free from cardiopulmonary disease. Resting calf blood flow in the infants with TGV was 3.6 +/- 0.8 ml/100 ml/min, while in the control group flow was 6.8 +/- 2.3 ml/100 ml/min, a highly significant difference. We postulate that newborns with TGV decrease their resting calf flow in response to chronic hypoxia.

    Since the early 1960's "resuscitation" following major trauma involved use of replacement crystalloid fluid/estimated blood loss in volumes of 3/1, in the ambulance, emergency room, operating room and surgical intensive care unit. During the past 20 years, MAJOR paradigm shifts have occurred in this concept. As a result hypotensive resuscitation with a view towards restriction of crystalloid, and prevention of complications has occurred. Improved results in both civilian and military environments have been reported. As a result there is new focus on trauma surgical involvement in all aspects of trauma patient management, focus on early aggressive surgical approaches (which may or may not involve an operation), and movement from crystalloid to blood, plasma, and platelet replacement therapy.

    This research investigated leadership and effectiveness of teams operating in a high-velocity environment, specifically trauma resuscitation teams. On the basis of the literature and their own ethnographic work, the authors proposed and tested a contingency model in which the influence of leadership on team effectiveness during trauma resuscitation differs according to the situation. Results indicated that empowering leadership was more effective when trauma severity was low and when team experience was high. Directive leadership was more effective when trauma severity was high or when the team was inexperienced. Findings also suggested that an empowering leader provided more learning opportunities than did a directive leader. The major contribution of this article is the linkage of leadership to team effectiveness, as moderated by relatively specific situational contingencies.

    Hemodynamic instability is associated with significant morbidity and mortality. Goal-directed therapeutic algorithms have been used in various clinical settings to reverse or prevent organ damage and death that could occur with a low oxygen delivery state. Most current resuscitative algorithms use static physiologic measures to determine if a patient will respond to proven therapies. While static parameters are useful in identifying the potential for clinical instability, they cannot tell us how patients will respond to an intervention. Applied physiology, through the use of functional hemodynamic monitoring can predict the body's reaction to therapy because they are based on cardiovascular dynamics. A growing body of evidence supports the use of applied physiologic principles in goal directed therapeutic algorithms for appropriate and effective resuscitation/optimization. Over time, applied physiology should be incorporated into standardized protocol-driven care to improve outcomes in patients experiencing, or at risk for hemodynamic instability. PMID:25479921

    Neonatal resuscitation is one of the most frequently performed procedures, and it is often successful if the ventilation applied is adequate. Over the last decade, interest in seeking objectivity in evaluating the infant’s condition at birth or the adequacy and effect of the interventions applied has markedly increased. Clinical parameters such as heart rate, color, and chest excursions are difficult to interpret and can be very subjective and subtle. The use of ECG, pulse oximetry, capnography, and respiratory function monitoring can add objectivity to the clinical assessment. These physiological parameters, with or without the combination of video recordings, can not only be used directly to guide care but also be used later for audit and teaching purposes. Further studies are needed to investigate whether this will improve the quality of delivery room management. In this narrative review, we will give an update of the current developments in monitoring neonatal resuscitation. PMID:27148507

    Noonan syndrome, an autosomal dominant disease occurring with an incidence of 1 in 1,000 to 1 in 2,500 live births, is characterized by its particular cardiovascular abnormalities, including pulmonic valve stenosis, pulmonary artery stenosis, and, more rarely, septal defects and coarctation of the aorta. The case of a 20-year-old man admitted for inpatient cardiopulmonary rehabilitation after pulmonic valve repair, left pulmonary artery angioplasty, and pectus excavatum repair is presented. His endurance was markedly decreased, thus limiting his ability to perform activities of daily living and reducing his exercise tolerance. With participation in a comprehensive cardiopulmonary rehabilitation program, he experienced marked improvement with independence in his activities of daily living and an increase in his metabolic equivalent levels from to 2.8 to 5.4. After inpatient rehabilitation, he underwent left pulmonary stent placement before being discharged home. Subsequent outpatient cardiopulmonary rehabilitation has continued to improve significantly his overall exercise tolerance. Given that Noonan syndrome is viewed as the most common syndrome associated with congenital heart disease after Down syndrome, physiatrists must be familiar with its presentation, its associated abnormalities, and the treatment approach to optimize the patient's cardiopulmonary, musculoskeletal, and psychological status.

    To examine the hypothesis that activated protein C system during cardiopulmonary bypass surgery may increase fibrinolytic activity during cardiopulmonary bypass, protein C activity, protein C antigen and thrombomodulin of sixteen patients undergoing elective cardiopulmonary bypass surgery were investigated after induction of anesthesia, before and after cardiopulmonary bypass, and at the end of operation. Protein C activity decreased and thrombomodulin increased significantly after the cardiopulmonary bypass. There were no significant correlations of thrombomodulin with protein C activity and protein C antigen. In conclusion, we have demonstrated that protein C system is activated and circulating thrombomodulin appears in the systemic circulation during cardiopulmonary bypass surgery and this enhanced activation of protein C system is possibly related to the reported increase of fibrinolytic activity during cardiopulmonary bypass.

    Newborns who are compromised at birth require rapid attention to stabilize their respiration attempts. Lack of knowledge regarding basic newborn resuscitation is a contributing factor to poor newborn health outcomes and increased mortality. The purpose of this study was to explore Jordanian midwives' experiences, education, and support needs to competently perform basic newborn resuscitation. Qualitative descriptive methodology was used to analyze a convenience sample of 20 midwives. A thematic approach was used to analyze the data. Participants discussed their experiences of basic newborn resuscitation including knowledge, skills, and barriers and suggested solutions to improve practice. Four themes were revealed: lack of knowledge and skills in newborn resuscitation, organizational constraints, inadequate teamwork, and educational needs. The midwives perceived that their ability to perform newborn resuscitation was hindered by lack of knowledge and skills in newborn resuscitation, organizational constraints (such as lack of equipment), and poor co-ordination and communication among team members.

    Tuberculosis (TB) is responsible for death of nearly two million people in the world annually. Upon infection, Mycobacterium tuberculosis (Mtb) causes formation of granuloma where the pathogen goes into dormant state and can live for decades before resuscitation to develop active disease when the immune system of the host is weakened and/or suppressed. In an attempt to better understand host-pathogen interactions, several groups have been developing in vitro models of human tuberculosis granuloma. However, to date, an in vitro granuloma model in which Mtb goes into dormancy and can subsequently resuscitate under conditions that mimic weakening of the immune system has not been reported. We describe the development of a biomimetic in vitro model of human tuberculosis granuloma using human primary leukocytes, in which the Mtb exhibited characteristics of dormant mycobacteria as demonstrated by (1) loss of acid-fastness, (2) accumulation of lipid bodies (3) development of rifampicin-tolerance and (4) gene expression changes. Further, when these micro granulomas were treated with immunosuppressant anti-tumor necrosis factor-alpha monoclonal antibodies (anti-TNFα mAbs), resuscitation of Mtb was observed as has been found in humans. In this human in vitro granuloma model triacylglycerol synthase 1deletion mutant (Δtgs1) with impaired ability to accumulate triacylglycerides (TG), but not the complemented mutant, could not go into dormancy. Deletion mutant of lipY, with compromised ability to mobilize the stored TG, but not the complemented mutant, was unable to come out of dormancy upon treatment with anti-TNFα mAbs. In conclusion, we have developed an in vitro human tuberculosis granuloma model that largely exhibits functional features of dormancy and resuscitation observed in human tuberculosis.
