To explore the use of oximetry as a guide for using respiratory aids and tracheotomy in the treatment of patients with amyotrophic lateral sclerosis (ALS). A retrospective review of all ALS patients presenting to a neuromuscular disease clinic since 1996. Patients who were symptomatic for nocturnal hypoventilation were prescribed noninvasive ventilation (NIV). Patients with assisted cough peak flows of < 300 L/min were prescribed oximeters and access to mechanically assisted coughing (MAC) to prevent or reverse decreases in baseline pulse oximetric saturation (Spo(2)) levels of < 95%. The number of decreases in baseline Spo(2) that could be normalized by any combination of NIV and MAC and the duration of normalization were recorded. When the baseline was not or could not be normalized, the time to acute respiratory failure and tracheotomy or death were recorded. Twenty-five patients became dependent on NIV, including 13 patients who received NIV continuously for a mean (+/- SD) period of 19.7 +/- 16.9 months, without desaturation (group 1). For another 76 patients, the daytime baseline Spo(2) level decreased to < 95% 78 times. For 41 patients, the baseline level was corrected by NIV/MAC (group 2) for a mean duration of 11.1 +/- 8.7 months before desaturation reoccurred for 27 patients. Of the latter patients, 11 underwent tracheotomy, 14 died in < 2 months, and 2 had their condition again corrected by the addition of MAC therapy. For 35 patients, the desaturation was not or could not be normalized (group 3). Thirty-three of these 35 patients required tracheotomy or died within 2 months. The only significant difference between groups 1 and 2 and group 3 was significantly poorer glottic function in the patients in group 3. Tracheotomy or death is highly likely within 2 months of a decrease in baseline Spo(2) that cannot be corrected by NIV or MAC. The long-term use of NIV and MAC, and the avoidance of tracheotomy is dependent on glottic function rather than on inspiratory or expiratory muscle failure.

Objective: To investigate the optimal time of tracheotomy/arytenoidectomy and the improvement of dyspnoea, dysphonia and dysphagia after arytenoidectomy with CO₂ laser in iatrogenic bilateral vocal folds paralysis patients. Method: Thirty patients [29 females, 56 (49-60) years, one male, 49 years] with bilateral vocal cords paralysis resulted from neck surgery were retrospectively analyzed by case archived information and following-up questionnaire. The data included patients' dysponea time, degree and duration from tracheotomy/arytenoidectomy to neck surgery. Twenty sixty patients required unilateral partial/total arytenoidectomy. The results of treatment were evaluated by questionnaire including dyspnoea, dysphonia and dysphagia. Result: All patients whose bilateral vocal paralysis were resulted from thyroid gland surgery. Dysponea occurred immediately after thyroidectomy surgery in 14 cases (46.7%), and 2 years later after thyroidectomy in 13 cases (43.3%), 8 years later in 3 cases (10.0%). There was one (3.3%) patient without tracheotomy. The duration of tracheotomy/arytenoidectomy to neck surgery was significantly correlated with duration of tracheotomy/arytenoidectomy to dyspnoea appearance ( r =0.879, P <0.05), not correlated with duration of thyroid surgery to dyspnoea appearance. There is significantly negative correlation between degree of dyspnoea and duration of tracheotomy/arytenoidectomy to neck surgery ( r =0.452, P <0.05). Twenty six patients appeared dyspnoea and underwent CO₂ laser arytenoidectomy after thyoidectomy 0.5-23 years. Five patients did unilateral total arytenoidectomy and 21 patients did unilateral partial arytenoidectomy. After 12-96 months following up, dyspnoea improved in 24 patients, no improved in 2 patients. Dysphonia improved and remained in 17 patients, being worse mildly in 8 patients and obviously in one patient. Dysphagia improved and remained in 24 patients, being worse in 2 patients. There was no difference between total and partial arytenoidectomy in dyspnoea, dysphonia and dysphagia. Conclusion: The morbidity of dyspnoea was correlated with time after neck surgery. It was rarely necessary to take tracheotomy immediately in bilateral vocal fords paralysis patients after neck surgery. The severer degree of dyspnoea led to shorter duration between neck surgery and tracheotomy/arytenoidectomy. There was obvious improvement after arytenoidectomy in dyspnoea, no significant change in dysphonia and dysphagia. The effect of total arytenoidectomy on bilateral vocal paralysis was similar to partial arytenoidectomy.

Conventional cuffed tracheotomy tubes do not prevent aspiration of secretions. Aspiration of saliva may be decreased with the use of a subglottic suction port. Prospective. Shiley Disposable Cuffed Tracheotomy (DCT) tubes sizes 4, 6, and 8 (Tyco Healthcare, Pleasanton, CA) were compared to Portex Blue Line Ultra Suctionaid (BLUS) tracheotomy tubes sizes 6, 7, and 8 (Fig 1; Smiths Medical, Watford, UK). All tubes were tested in a simulated tracheal model using 10 cc of human saliva with no suction, intermittent suction, and constant suction (15 minutes). There was a significant decrease in aspirate between the larger Shiley and BLUS tubes with intermittent suction (mean 8.38 mL Shiley 6 vs 1.60 mL BLUS 7; 8.50 mL Shiley 8 vs 2.80 mL BLUS 8). There was a significant decrease in aspirate between all sizes of Shiley and BLUS tubes with continuous suction. For BLUS 7 and 8, there was a significant difference between intermittent suction (mean, 1.60 mL, 2.80 mL, respectively) and continuous suction (mean, 0.20 mL, 0.60 mL respectively). Shiley and BLUS without suction were equivalent. Subglottic suction tracheotomy tubes reduce the risk of aspiration beyond the cuff in a bench-top model.

To investigate physiologic parameters, voice production abilities, and functional verbal communication ratings of the Blom low profile voice inner cannula and Passy-Muir one-way tracheotomy tube speaking valves. Case series with planned data collection. Large, urban, tertiary care teaching hospital. Referred sample of 30 consecutively enrolled adults requiring a tracheotomy tube and tested with Blom and Passy-Muir valves. Physiologic parameters recorded were oxygen saturation, respiration rate, and heart rate. Voice production abilities included maximum voice intensity in relation to ambient room noise and maximum phonation duration of the vowel/a/. Functional verbal communication was determined from randomized and blinded listener ratings of counting 1-10, saying the days of the week, and reading aloud the sentence, "There is according to legend a boiling pot of gold at one end." There were no significant differences (p>0.05) between the Blom and Passy-Muir valves for the physiologic parameters of oxygen saturation, respiration rate, and heart rate; voice production abilities of both maximum intensity and duration of/a/; and functional verbal communication ratings. Both valves allowed for significantly greater maximum voice intensity over ambient room noise (p<0.001). The Blom low profile voice inner cannula and Passy-Muir one-way speaking valves exhibited equipoise regarding patient physiologic parameters, voice production abilities, and functional verbal communication ratings. Readers will understand the importance of verbal communication for patients who require a tracheotomy tube; will be able to determine the differences between the Blom low profile voice inner cannula and Passy-Muir one-way tracheotomy tube speaking valves; and will be confident in knowing that both the Blom and Passy-Muir one-way tracheotomy tube speaking valves are equivalent regarding physiological functioning and speech production abilities.

The purpose of this study was to evaluate the safety and efficacy of direct intralesional ethanol sclerotherapy for venous malformations (VMs) with oropharyngeal involvement after a temporary tracheotomy. A retrospective assessment was carried out to evaluate the efficacy of direct intralesional ethanol sclerotherapy on 21 consecutive patients presenting with extensive VMs involving the oropharynx in the head and neck and who had undergone tracheotomy. Of the 21 patients, 4 were treated once and 17 were treated from 2 to 5 times. The duration of follow-up was, on average, 9.1 months. Of the 21 patients, 7 (33.3%) had complete palliation, whereas the rest (66.7%) achieved partial palliation. Minor complications occurred in 12 of the 21 patients. Direct intralesional ethanol sclerotherapy after a temporary tracheotomy is a safe and effective treatment for extensive VMs involving oropharyngeal areas of the head and neck. © 2016 Wiley Periodicals, Inc.

We describe an innovative computer-based method for the analysis of gas flow using a modified airway management technique to perform percutaneous dilatational tracheotomy (PDT) with a rigid tracheotomy endoscope (TED). A test lung was connected via an artificial trachea with the tracheotomy endoscope and ventilated using superimposed high-frequency jet ventilation. Red packed cells were instilled during the puncture phase of a simulated percutaneous tracheotomy in a trachea model and migration of the red packed cells during breathing was continuously measured. Simultaneously, the calculation of the gas-flow within the endoscope was numerically simulated. In the experimental study, no backflow of blood occurred during the use of superimposed high-frequency jet ventilation (SHFJV) from the trachea into the endoscope nor did any transportation of blood into the lower respiratory tract occur. In parallel, the numerical simulations of the openings of TED show almost positive volume flows. Under the conditions investigated there is no risk of blood aspiration during PDT using the TED and simultaneous ventilation with SHFJV. In addition, no risk of impairment of endoscopic visibility exists through a backflow of blood into the TED. The method of numerical simulation offers excellent insight into the fluid flow even under highly transient conditions like jet ventilation.

The aim of the work was to assess early complications of Griggs percutaneous tracheotomy in the own material. The study covered 155 patients aged 17-88, including 36 women and 119 men. The patients were treated at the Department of Anaesthesiology and Intensive Therapy between 2006-2010. They underwent Griggs percutaneous tracheostomy by a laryngologist or a trained anaesthesiologist. Each surgical procedure was conducted with the use of Portex Blue Line Ultra Percutaneous Tracheotomy Kit (Smiths Medical Co., USA), the trachea was intubated while the patient was under general anaesthesia with propofol, fentanyl and relaxation with atracurium. The studied material revealed Griggs percutaneous tracheotomy complications in 26 patients (16.8%), in which 11 patients (7.1%) presented complications within the perioperative period while 15 patients (9.7%) reported early complications. Haemorrhage, usually not very profuse, occurred 7 times (4.6%), mainly in tracheopunction, and was the most often perioperative complication. Moreover, in the perioperative period, 3 patients (1.9%) had trachea identifications difficulties, which required tracheopunction many a time, and 1 patient (0.65%) encountered sudden circulatory arrest with asystolia and effective CPR. In the early postoperative period after Griggs percutaneous tracheotomy, the most common complication was haemorrhage in the operative twenty-four hours, which was noted in 10 patients (6.5%). Among other adverse complications were found: infection of the tissues near the tracheostomal region in 3 patients (1.9%), subcutaneous oedema in 1 patient (0.65%), accidental removing the tube from an unformed tracheostoma in 1 patient (0.65%). In the studied material, complications after Griggs percutaneous tracheotomy amounted to 16.8%, of which 7.1% occurred in the perioperative period while 9.7% were early complications, mainly light bleeding. This may prove good preparation of the surgical team for the surgical procedures. Copyright © 2012 Polish Otolaryngology Society. Published by Elsevier Urban & Partner Sp. z.o.o.

To estimate the current birth prevalence of isolated and syndromic Pierre Robin sequence (iPRS and sPRS), including demographic variations. To assess for regional variations in surgical airway interventions for PRS, and to determine the mean length of stay (LOS), cost of admission, complication rate, and rate of associated procedures related to tongue-lip adhesion (TLA), neonatal mandibular distraction osteogenesis (MDO), and tracheotomy. Retrospective cross-sectional study. The 2006 and 2009 Kids Inpatient Databases were used to identify newborns and infants with PRS; analysis using cross tabulations and linear regression modeling was performed. In 2006 and 2009, the estimated birth prevalence of iPRS was 1.8:10,000 live births and sPRS 1.4:10,000 live births. The highest rate was in whites and the lowest in non-Hispanic blacks. There were 145 TLAs (36%), 176 MDOs (43%), and 85 tracheotomies (21%). The Northeast favored a TLA strategy; the Midwest favored MDO. The mean LOS for TLA was 24.5 days, MDO 36.7 days, tracheotomy (iPRS) 44.9 days, and tracheotomy (sPRS) 53.0 days. The birth prevalence of PRS may be higher than previously described, especially in whites. Surgical management strategies vary between regions. The overall cost of a TLA admission is lower than an MDO or tracheotomy admission, owing primarily to shorter LOS. This study was limited by not taking into account outpatient expenses (nursing care, monitoring) or need for further airway/feeding intervention over subsequent admissions. 2c. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

To analyze the safety of a standardized pediatric tracheostomy care protocol in the immediate postoperative period and its impact on tracheostomy related complications. Retrospective case series. Pediatric patients undergoing tracheotomy from February 2010-February 2014. In 2012, a standardized protocol was established regarding postoperative pediatric tracheostomy care. This protocol included securing newly placed tracheostomy tubes using a foam strap with hook and loop fastener rather than twill ties, placing a fresh drain sponge around the tracheostomy tube daily, and performing the first tracheostomy tube change on postoperative day 3 or 4. Outcome measures included rate of skin breakdown and presence of a mature stoma allowing for a safe first tracheostomy tube change. Two types of tracheotomy were performed based on patient age: standard pediatric tracheotomy and adult-style tracheotomy with a Bjork flap. Patients were analyzed separately based on age and the type of tracheotomy performed. Thirty-seven patients in the pre-protocol group and 35 in the post-protocol group were analyzed. The rate of skin breakdown was significantly lower in the post-protocol group (standard: p=0.0048; Bjork flap: p=0.0003). In the post-protocol group, all tube changes were safely accomplished on postoperative day three or four, and the stomas were deemed to be adequately matured to do so in all cases. A standardized postoperative pediatric tracheostomy care protocol resulted in decreased rates of skin breakdown and demonstrated that pediatric tracheostomy tubes can be safely changed as early as 3 days postoperatively.

Pierre-Robin syndrome (PRS) is often associated with difficulty in endotracheal intubation. We present the use of percutaneous dilational tracheotomy (PDT) for airway management of a newborn with PRS and a glossopharyngeal web. A 2-day-old term newborn with PRS and severe obstructive dyspnea was evaluated by the anesthesiology team for airway management. A direct laryngoscopy revealed a glossopharyngeal web extending from the base of the tongue to the posterior pharyngeal wall. The infant was spontaneously breathing through a 2 mm diameter fistula in the center of this web. It was decided that endotracheal intubation was impossible, and a PDT was planned. The trachea of the newborn was cannulated, using a 20 gauge peripheral venous catheter and a 0.71 mm guide wire was introduced through this catheter. Using 5 French, 7 French, 9 French, and 11 French central venous catheter kit dilators, staged tracheotomy stoma dilation was performed. By inserting a size 3.0 tracheotomy cannula, PDT was successfully completed in this newborn. This case describes the successful use of PDT for emergency airway management of a newborn with PRS and glossopharyngeal web.

Although tracheotomy had been described in the Middle Ages and especially in the 17th century in writings (Fabricius d'Aquapendente 1620) and illustrations (Scultetus 1645), there was hardly any possibility of actually performing this operation as a life-saving intervention until the middle of the 19th century. It was only after suitable cannulae had been introduced by Trousseau in 1851 (double cannula with removeable insert) that tracheotomy became a routine procedure, and it was immediately carried out in a great many cases of diphtheria, croup, typhus, and lues, which often caused critical dispnea. Within the following 25 years, all technical modifications of cannulae were devised that are in use up to this day: the flap valve for the artificial larynx (1861), inflatable cuff (1871), and extra long flexible cannula. Beginning in 1885, O'Dwyer's method of intubation became established as an alternative to tracheotomy. Both procedures, like the underlying disease itself, frequently resulted in a permanent stenosis of the larynx or the trachea rendering decannulation impossible. Since about 1870 the treatment of these stenoses, primarily by bougienage, became an important issue in laryngology, which had just been established as a discipline in its own right. The history of this evolution and the therapeutic approaches by Schrötter in Vienna and Thost in Hamburg are described in detail, including their specially devised equipment. Apart from that, other medical aspects of historical interest around the turn of the century are mentioned, such as artificial nutrition by subcutaneous injections and tracheotomy in horses.(ABSTRACT TRUNCATED AT 250 WORDS)

Successful Kissing Balloon Expandable Stent Graft Treatment for a Right Common Carotid Pseudoaneurysm Caused by Tracheotomy.

A rare complication following tracheotomy is common carotid artery (CCA) pseudoaneurysm. Treatment modalities for CCA pseudoaneurysm include surgical repair and single-artery balloon-covered stent graft technique. We describe successful treatment of tracheotomy-related CCA pseudoaneurysm with the "kissing balloon" expandable stent graft technique. We successfully implemented the kissing balloon expandable stent graft technique for treatment of a large, narrow-necked, bilobed CCA pseudoaneurysm that arose owing to a tracheotomy complication. The pseudoaneurysm was detected while performing a diagnostic angiogram of the aortic arch and surrounding vessels. The stent was deployed while the 2 balloons were introduced in a kissing manner such that they faced one another to avoid occlusion of either branch of the innominate artery coming into contact; 1 balloon was inflated at the origin of the right subclavian artery, and the other was inflated at the right innominate artery simultaneously. The pseudoaneurysm was successfully contained; normal blood flow was restored in the CCA. The balloons were deflated and withdrawn. The patient remained neurologically intact after the procedure. The kissing balloon technique is a safe and effective alternative to surgical repair, as it prevents morbidities associated with the surgical procedure. Also, this technique decreases the risk of major side-branch occlusion associated with the single-artery balloon-covered stent graft technique. Copyright © 2018 Elsevier Inc. All rights reserved.

2006-01-01

In patients presenting a bilateral laryngeal immobility, the potential reversibility of certain cases, the refusal or the bad tolerance of long term tracheotomy bring up the question of the choice of the surgical technique if it is indicated. To report our experience with the technique of lateralization of the paralyzed vocal fold (arytenoidopexy) suggested by Lichtenberger. After having described the technique, we report 5 cases (3 pos-thyroidectomy, I of central origine, 1 post-burn). From 1 to 12 months after surgery 2 patients were fully satisfied, a patient (central origin) recovered spontaneously at the end of a month and the 2 last had a partial result. Only one patient required several surgical gestures. The Lichtenberger's technique combines theoretical reversibility and conservation of a functional glottic plan. It avoids tracheotomy. This approach can according to us validly replace the traditional techniques, medium or long term tracheotomy , or endoscopic arythenoid or posterior vocal fold resection.

Bilateral vocal cord paralysis in children with its many causes presents a challenging problem to the pediatric otolaryngologist. Traditionally, management of bilateral vocal cord paralysis includes securing the airway with a tracheotomy and waiting for spontaneous recovery. Surgeons have tried a variety of surgical procedures in lieu of or in addition to tracheotomy, but none are perfect solutions to the problem. This article reviews the current surgical procedures for bilateral vocal cord paralysis in the pediatric population with a particular focus on the senior author's experience with the endoscopic posterior costal cartilage grafting procedure.

Forced vital capacity (FVC) <80% is one of the key indications for starting non-invasive ventilation (NIV) in amyotrophic lateral sclerosis (ALS). It was hypothesized that a very early start of NIV could lengthen the free interval before death compared to later-start NIV; as a secondary outcome, the survival rate of patients on NIV without tracheotomy was also evaluated. This retrospective study was conducted on 194 ALS patients, divided into a later group (LG) with FVC <80% at NIV prescription (n = 129) and a very early group (VEG) with FVC ≥80% at NIV prescription (n = 65). Clinical and respiratory functional data and time free to death between groups over a 3-year follow-up were compared. At 36 months from diagnosis, mortality was 35% for the VEG versus 52.7% for the LG (P = 0.022). Kaplan-Meier survival curves adjusted for tracheotomy showed a lower probability of death (P = 0.001) for the VEG as a whole (P = 0.001) and for the non-bulbar (NB) subgroup (P = 0.007). Very early NIV was protective of survival for all patients [hazard ratio (HR) 0.45; 95% confidence interval (CI) 0.28-0.74; P = 0.001] and for the NB subgroup (HR 0.43; 95% CI 0.23-0.79; P = 0.007), whilst a tracheotomy was protective for all patients (HR 0.27; 95% CI 0.15-0.50; P = 0.000) and both NB (HR 0.26; 95% CI 0.12-0.56; P = 0.001) and bulbar subgroups (HR 0.29; 95% CI 0.11-0.77; P = 0.013). Survival in VEG patients on NIV without tracheotomy was three times that for the LG (43.1% vs. 14.7%). Very early NIV prescription prolongs the free time from diagnosis to death in NB ALS patients whilst tracheotomy reduces the mortality risk in all patients. © 2017 EAN.

Dilatational tracheotomy techniques are widely used in the long-term management of the respiratory tract in patients in intensive care units (ICU). The translaryngeal tracheotomy technique (TLT) was first described by Fantoni in 1993 and rapidly asserted itself, especially in Europe. This technique basically differs from the other percutaneous techniques in that it involves a progressive, retrograde, dilatation of the trachea in a single session conducted from inside the trachea, working outward, simultaneously exerting a counter-pressure on the pre-tracheal soft tissues with the fingers. The present study involves an endoscopy follow-up of 130 patients who had undergone TLT at the Intensive Care Unit of our Hospital between November 2000 and May 2001. The pre-operative oro-tracheal intubation time varied from 1 to 42 days. All patients filled out a brief questionnaire containing validated questions on their general health and quality of life with particular attention focused on respiratory conditions. Then, after receiving informed consent, the patients underwent laryngo-tracheoscopy with local anesthetic using a flexible tracheobronchoscope. All tests were recorded and viewed later by two operators in order to identify and divide the patients according to the level of execution of the tracheotomy and the presence of sequelae. The results obtained have shown that, like other percutaneous tracheotomy techniques, TLT provides some benefits including the fact that procedure can be performed at the bedside in a short time, with few post-operative complications, simpler nursing and fewer sequelae in time. Analysis of data concerning time of tracheostomy execution, tracheal level of stomia and nursing times has revealed three factors that determine severe sequelae: delay in tracheostomy execution, high level of execution with cricoid involvement and onset of problems during first tracheal cannula change.

Respiratory-related electromyographic (EMG) activity of the superior pharyngeal constrictor (SPC) muscle was analyzed during the early stage of forced breathing. Four adult dogs anesthetized with sodium pentobarbital were used. In the first part of the study, oral and nasal breathing tubes were placed into the respective cavities, and a tracheotomy tube was placed in the second part of the study. Two conditions, the presence (oral-nasal tube breathing) and absence (tracheotomy breathing) of airflow in the upper airway, were achieved in each dog. Following quiet breathing, animals were connected to a closed breathing system, first by an oral-nasal tube and then by a tracheotomy tube. We proposed to induce a forced breathing condition mechanically by using this system for 1 minute. We increased resistance to airflow during forced breathing by means of connecting tubes and a bag. Our aim was not to produce chemical drive but to produce a forced respiration by increasing the resistance to airflow. Tidal volume, breathing frequency, minute volume, chest wall movement, and EMG activity of the SPC muscle were measured and analyzed. During quiet breathing through an oral-nasal or tracheotomy tube, low-amplitude EMG activity of the SPC muscle corresponding to the expiratory cycle of the respiration was observed. In both study conditions, phasic expiratory EMG activity increased immediately after the advent of the breathing from the closed system. Tidal volumes and frequencies also increased rapidly during forced breathing. An increase in the resistance to airflow increased the activity of the SPC muscle. This augmented respiratory activity probably assists the patency of the upper airway. The augmented respiratory activity was independent of the local reflex pathways. Respiratory-related activity of the SPC muscle may help dilate and stiffen the pharyngeal airway, promoting airway patency.

Two 16 g needles and one 1/0 nylon thread were used for the procedure with 1 cm skin incision; no tracheotomy or tissue excision was required. Pre-post-operative photographs of the glottic region were taken from the endoscopic records, and the areas of rima glottis openings were calculated with the Image-J programme. Forty-seven patients were analyzed. The mean pre-post-operative rima glottis areas were 1.11 ± 0.56 and 2.24 ± 0.93 mm(2), respectively (p < 0.001). Five patients with previous tracheotomy were decannulated within a few days after the operation. In three patients, mild complications developed in the early post-operative period (two laryngeal edemas, one submucosal hematoma). Tracheotomy was performed to only one pregnant patient in the post-operative first day. None of the patients had granulation formation or synechia.

Assessment of humidifying function of tracheotomy speaking valves with integrated heat and moisture exchanger. Ex vivo measurement of water exchange and storage capacity of three tracheotomy speaking valves: Humidiphon Plus, Spiro and ProTrach DualCare (with two different heat and moisture exchangers: XtraMoist and Regular). Comprehensive Cancer Centre. Healthy volunteer. Difference between end-inspiratory and end-expiratory weight as measure for water exchange capacity, weight after 10 min breathing as measure for water storage capacity, weighing at 1-min intervals to assess residual water exchange potential in speaking mode and absolute humidity in mg/L as measure for environmental and respiratory humidity. None of the tracheotomy speaking valves provides humidification while in speaking mode. Only the ProTrach DualCare allows blocking the speaking valve and breathing through the heat and moisture exchanger during inhalation and exhalation (heat and moisture exchanger mode). This leads to an increase in inspiratory humidity of 2.5 mg (XtraMoist) and 1.6 mg (Regular). There was no measurable water storage in speaking mode in any of the three tracheotomy speaking valves. In breathing mode, water storage in the DualCare heat and moisture exchangers was 47 and 37 mg, respectively. The remaining humidifying potential in speaking mode after 10 min breathing in heat and moisture exchanger mode for XtraMoist was 38%, 15% and 10% at 1, 2 and 3 min, respectively. For Regular, this was 47%, 24% and 13%, respectively. Tracheostoma valves with integrated heat and moisture exchanger have no humidification function in speaking mode. Only ProTrach DualCare, allowing blocking the speaking mode, in heat and moisture exchanger mode enables a significant increase in humidification. Regular switching between speaking and heat and moisture exchanger mode with this latter device prolongs the humidification in speaking mode. © 2015 John Wiley & Sons Ltd.

The purpose of this study was to establish a rat model of a brain injury with tracheotomy and compared the wetting effects of different airway humidification liquids, afterward, the best airway humidification liquid was selected for the clinical trial, thus providing a theoretical basis for selecting a proper airway humidification liquid in a clinical setting. Rats were divided into a sham group, group A (0.9% NaCl), group B (0.45% NaCl), group C (0.9% NaCl+ambroxol) and group D (0.9% NaCl+Pulmicort). An established rat model of traumatic brain injury with tracheotomy was used. Brain tissue samples were taken to determine water content, while lung tissue samples were taken to determine wet/dry weight ratio (W/D), histological changes and expression levels of SP-A mRNA and SP-A protein. 30 patients with brain injury and tracheotomy were selected and divided into two groups based on the airway humidification liquid instilled in the trachea tube, 0.45% NaCl and 0.9% NaCl+ambroxol. Blood was then extracted from the patients to measure the levels of SP-A, interleukin-6 (IL-6), interleukin-8 (IL-8) and tumour necrosis factor-α (TNF-α). The difference between group C and other groups in lung W/D and expression levels of SP-A mRNA and SP-A protein was significant (P<0.05). In comparison, the histological changes showed that the lung tissue damage was smallest in group C compared to the three other groups. Aspect of patients, 0.45% NaCl group and 0.9% NaCl+ambroxol group were significantly different in the levels of SP-A, IL-6, IL-8 and TNF-α (P<0.01). In the present study, 0.9% NaCl+ambroxol promote the synthesis and secretion of pulmonary surfactant, and has anti-inflammatory and antioxidant effects, which inhibit the release of inflammatory factors and cytokines, making it an ideal airway humidification liquid.

Management of complex glottic stenosis in children with recurrent respiratory papillomatosis.

Siegel, Bianca; Smith, Lee P

2013-10-01

To describe our management of complex glottic stenosis in tracheotomy dependent children with severe recurrent respiratory papillomatosis. Retrospective chart review at a tertiary care children's hospital. Three children with complex glottic stenosis secondary to severe recurrent respiratory papillomatosis were treated at our institution since 2011. Two patients had complete stenosis, and the third had near-complete stenosis. Two patients were managed using balloon dilation alone, and the third also underwent laryngotracheal reconstruction with posterior costal cartilage grafting. Two patients have been successfully decannulated and the third has been tolerating continuous tracheotomy capping for greater than twelve months. All three patients underwent aggressive debridement of papillomatosis and balloon dilation every 4-6 weeks until their burden of disease was controlled. In two patients, the glottic airway was patent, and the third continued to have complete restenosis between procedures and required laryngotracheoplasty with multiple post-operative dilation procedures to establish an adequate glottic airway. Severe laryngeal stenosis is a well-described complication of recurrent respiratory papillomatosis, but its management is not well-defined. Aggressive management of papillomatosis with frequent debridement is critical in successfully managing laryngeal stenosis. Balloon dilation alone may be surprisingly effective in these patients, and laryngotracheoplasty can be used as an adjunct procedure in those patients who fail balloon dilation. Given the quality of life issues and concerns regarding distal spread of disease with tracheotomies in these patients, we feel that aggressive management and early decannulation is in the patient's best interest.

To evaluate the incidence of pharyngocutaneous fistula after total laryngectomy and try to identify its predictors. From May 2005 to April 2010, 93 patients underwent total laryngectomy. We evaluated complications during and after surgery and compared them with the following variables: gender, nutritional status, previous tracheotomy, tumor location, type of surgery, TNM staging, prior treatment with chemotherapy and/or radiotherapy, use of flaps for reconstruction and surgical margin. All patients presented with advanced neoplastic disease according to TNM. 14 (15.1%) patients developed postoperative salivary fistula. The mean time to onset of salivary fistula was 3.5 days, with a standard deviation of 13.7 days. Comparing salivary fistula with TNM variables, type of operation and neck dissection, prior tracheotomy, use of flap, preoperative radio and chemotherapy and surgical margin, there was no statistically significant difference (p> 0,05). The incidence of salivary fistula was 15.1% and no predictive factor for its formation was found.

Tracheostomy cannulas and voice prosthesis

Cannulas and voice prostheses are mechanical aids for patients who had to undergo tracheotomy or laryngectomy for different reasons. For better understanding of the function of those artificial devices, first the indications and particularities of the previous surgical intervention are described in the context of this review. Despite the established procedure of percutaneous dilatation tracheotomy e.g. in intensive care units, the application of epithelised tracheostomas has its own position, especially when airway obstruction is persistent (e.g. caused by traumata, inflammations, or tumors) and a longer artificial ventilation or special care of the patient are required. In order to keep the airways open after tracheotomy, tracheostomy cannulas of different materials with different functions are available. For each patient the most appropriate type of cannula must be found. Voice prostheses are meanwhile the device of choice for rapid and efficient voice rehabilitation after laryngectomy. Individual sizes and materials allow adaptation of the voice prostheses to the individual anatomical situation of the patients. The combined application of voice prostheses with HME (Head and Moisture Exchanger) allows a good vocal as well as pulmonary rehabilitation. Precondition for efficient voice prosthesis is the observation of certain surgical principles during laryngectomy. The duration of the prosthesis mainly depends on material properties and biofilms, mostly consisting of funguses and bacteries. The quality of voice with valve prosthesis is clearly superior to esophagus prosthesis or electro-laryngeal voice. Whenever possible, tracheostoma valves for free-hand speech should be applied. Physicians taking care of patients with speech prostheses after laryngectomy should know exactly what to do in case the device fails or gets lost. PMID:22073098

Objectives Elective tracheotomy (ET) procedures in intensive care units (ICU) might be different in accordance with countries and ICUs’ features. The aim of the present study was to search the epidemiology of ET procedures in Turkey. Methods A questionnaire which consists of 43 questions was sent by e-mail to 238 ICUs which were officially recognized by The Turkish Ministry of Health. All answers were obtained between August 1, 2015 and August 31, 2015. Results Two hundred and three ICUs (85.3%) participated in this study. 177 (87.2%) and 169 (83.4%) of ICU’s were level III and mixed ICUs respectively. Anesthesiologists were the director of 189 (93.0%) ICUs. Estimated total count of admitted, mechanically ventilated and tracheotomized patients in 2014 were 126282, 80569 (63.8%) and 8989 (7.1%) respectively. Most common indication for ET was prolonged mechanical ventilation (76.9%). The first choice for ET procedure was percutaneous in 162 (79.8%) ICUs. Griggs guide wire dilatational forceps (GWDF) technique was used as the first choice for elective percutaneous tracheotomy (EPT) by 143 (70.4%) ICUs. Most common early EPT complication was bleeding (68.0%) and late EPT complication was stenosis (35.0%). While facilitation of weaning was most important advantage (26.1%), bleeding and tracheal complications were most important disadvantages for EPT (29.1%). Conclusions Most common indications for ET are prolonged MV and coma in Turkish ICUs. EPT is the preferred procedure for ET and GWDF is the most common technique. Bronchoscopy and USG are rarely used as a guide. PMID:27846248

To analyse the efficacy of CO(2) laser arytenoidectomy in the management of bilateral vocal cord paralysis in children. Retrospective series of 17 patients who underwent laser arytenoidectomy for bilateral vocal cord between 1995 and 2008 in a tertiary care institution. All patients had bilateral laryngeal paralysis, in isolation (n=5) or associated with concomitant airway conditions (n=12). All cases had anterior prolapse of the arytenoids with partial obstruction of the airway on inspiration. 12/17 patients (70.5%) were tracheotomy-dependant, 2/17 were in-extubatable, and 3/17 had severe airway limitation, effort dyspnea and poor sleep pattern. Main outcome measures were decannulation rate for patients with tracheotomy, occurrence of aspiration and quality of voice. The mean age was 2.8 years old. 9/12 patients with tracheotomy (75%) were decannulated with a median delay of 2 months (2 days to 18 months). Both of the intubated patients were extubated with a median delay of 36h. One of the decannulated patients who re-presented with a residual dyspnea after the arytenoidectomy was improved by a further laser cordotomy. 2/17 patients (11.7%) had post-operative persistent aspirations (with pneumopathies in one case), 5/17 patients were dysphonic, 3 improved with speech therapy and 2 with intracordal lipoinjection. Laser arytenoidectomy is effective for improving the breathing in children presenting with a bilateral vocal fold paralysis associated with obstructive arytenoid prolapse. Results are good as a first-line surgery or following laryngo-tracheal surgery. Voice outcomes are satisfactory. However, aspiration is a rare complication. Copyright (c) 2010 Elsevier Ireland Ltd.

To Analyze the influence factors on the complications of percutaneous dilational tracheotomy. Between August 2008 and February 2014, there were 3 450 patients with the indications of tracheotomy accepted percutaneous dilational tracheostomy, mainly using percutaneous dilational and percutaneous guide wire forceps in these cases. Statistical analysis was performed by SPSS 19.0 software on postoperative complications, the possible influence factors including age, gender, etiology, preoperative hypoxia, obesity, preoperative pulmonary infection, state of consciousness, operation method, operation doctor and whether with tracheal intubation. Among 3 450 patients, there were 164 cases with intraoperative or postoperative complications, including postoperative bleeding in 74 cases (2.14%), subcutaneous emphysema in 54 cases (1.57%), wound infection in 16 cases (0.46%), pneumothorax in 6 cases (0.17%), mediastinal emphysema in 5 cases (0.14%), operation failed and change to conventional incision in 4 cases (0.12%), tracheoesophageal fistula in 2 cases (0.06%), death in 3 cases(0.09%).Obesity, etiology, preoperative hypoxia, preoperative pulmonary infection, state of consciousness and operation method were the main influence factors, with significant statistical difference (χ(2) value was 0.010, 0.000, 0.002, 0.000, 0.000, 0.000, all P < 0.05). Gender, age, operation doctor and whether there was the endotracheal intubation were not the main influence factors. There was no significant statistical difference (P > 0.05). Although percutaneous dilational tracheostomy is safe, but the complications can also happen. In order to reduce the complications, it is need to pay attention to the factors of obesity, etiology, preoperative hypoxia, preoperative pulmonary infection, state of consciousness and operation method.

Home care for respiratory patients includes a complex array of services delivered in an uncontrolled setting. The role of a respiratory specialist inside the home healthcare team has been scarcely studied up to now. Our aims were to analyse the number and quality of episodic home visits performed by respiratory physicians to severe bedridden Chronic Respiratory Failure (CRF) patients, and also to evaluate the safety of tracheotomy tube substitutions at home. 231 home interventions (59.8/year) in 123 CRF patients (59 males; age 63 +/- 17 y, 24 on oxygen therapy, 35 under non invasive mechanical ventilation, 46 under invasive ventilation, 74 with tracheostomy) located 35 +/- 16 km far from referred hospital, were revised in a period of 4 years (2005-2008). Chronic Obstructive Pulmonary Disease (COPD) (31%) and amyotrophic lateral sclerosis (ALS) (28%) were the more frequent diagnoses. Interventions were: tracheotomy tube substitution (64%) presenting 22% of minor adverse events and 1.4% of major adverse events; change or new oxygen prescription (37%); nocturnal pulsed saturimetric trend prescription (24%); change in mechanical ventilation (MV) setting (4%); new MV adaptation (7%). After medical intervention, new home medical equipment devices (oxygen and MV) were prescribed in 36% of the cases while rehabilitative hospital admission and home respiratory physiotherapy prescription was proposed in 9% and 6% of the cases respectively. Patient/caregiver's satisfaction was reported on average 8.48 +/- 0.79 (1 = the worst; 10 = the higher). The local health care system (HCS) reimbursed 70 euros for each home intervention. Families saved 42 +/- 20 euros per visit for ambulance transportation. Home visits performed by a respiratory physician to bedridden patients with chronic respiratory failure: 1. include predominantly patients affected by COPD and ALS; 2. determine a very good satisfaction to patients/caregivers; 3. allow money saving to caregivers; 4. are predominantly made up to change tracheotomy tube without severe adverse events.

Bioresorbable distraction device for the treatment of airway problems for infants with Robin sequence.

Pierre Robin sequence is a well known craniofacial entity. There are numerous ways to treat the respiratory insufficiency, but sometimes surgical intervention is needed. Tracheotomy could be associated with morbidity, and distraction osteogenesis has been established as a stable method to obtain a safe airway. Distraction osteogenesis has traditionally been performed with an external device. In this manuscript we describe the feasibility of an internal bioresorbable device. Retrospective descriptive study was performed in a tertiary academic children's hospital. After multidisciplinary team consultation, 12 consecutive patients with Robin sequence were treated with this internal distraction device. The mean age at surgery was 32 days, and the average amount of mandibular distraction was 18 mm. All patients were extubated after an average of 7.5 days after the surgery. The average length of stay in the hospital was 17 days after surgery. There were no major surgical complications. A tracheotomy was prevented in all our patients, and complications were limited. Long-term studies are needed to evaluate the influence that internal distraction has on the growth of the mandible and teeth. The internal distraction system seems safe for infants with micrognathia and has certain benefits when compared to the external distractor.

Surgical management of obstructive sleep apnea in children with cerebral palsy.

Magardino, T M; Tom, L W

1999-10-01

To evaluate the surgical management of obstructive sleep apnea in children with cerebral palsy. Retrospective review of 27 children with cerebral palsy who underwent surgical treatment for obstructive sleep apnea. Charts were reviewed. Data gathered included primary complaint, coexisting illnesses, initial procedure performed, age at initial surgery, number of days the child was monitored postoperatively in the intensive care unit, notation of postoperative respiratory distress and management, and outcome. Nineteen children underwent adenotonsillectomy for initial treatment of obstructive sleep apnea. Three of these children also had a uvulectomy. Six children had an adenoidectomy alone as their initial procedure. Neither uvulopalatopharyngoplasty nor tracheostomy was performed as an initial procedure. Mean follow-up was 34 months. Seventy-six percent of these children have not required any further surgery. Of the six children who have undergone further surgery, one has required a revision adenoidectomy, and another underwent a tonsillectomy and uvulectomy 2 months after the initial adenoidectomy. Four children ultimately required a tracheotomy. Eighty-four percent of these children were successfully managed without a tracheotomy. We recommend tonsillectomy and/or adenoidectomy for initial surgical treatment of obstructive sleep apnea in children with cerebral palsy.

Differential lung ventilation via tracheostomy using two endotracheal tubes in an infant: a case report.

This case report presents differential lung ventilation in an infant. The aim is to define an alternative technique for performing differential lung ventilation in children. To the best of our knowledge, this is the first report of this kind. A 4.2-kg, 2.5-month-old Asian boy was referred to our facility with refractory hypoxemia and hypercarbia due to asymmetric lung disease with atelectasis of the left lung and hyperinflation of the right lung. He was unresponsive to conventional ventilator strategies; different ventilator settings were required. To perform differential lung ventilation, two separate single-lumen endotracheal tubes were inserted into the main bronchus of each lung by tracheotomy; the tracheal tubes were attached to discrete ventilators. The left lung was ventilated with a lung salvage strategy using high-frequency oscillatory ventilation, and the right lung was ventilated with a lung-protective strategy using pressure-regulated volume control mode. Differential lung ventilation was performed successfully with this technique without complications. Differential lung ventilation may be a lifesaving procedure in select patients who have asymmetric lung disease. Inserting two single-lumen endotracheal tubes via tracheotomy for differential lung ventilation can be an effective and safe alternative method.

We report obstructive sleep apnea in a 3-year-old boy with tracheomalacia secondary to tracheotomy that resolved after placement of a metallic stent in the region of tracheomalacia. The tracheal location of obstruction during sleep in this case contrasts with the usual location in the pharynx or, less often, the larynx. This case also demonstrates the utility of polysomnography in managing decannulation of tracheostomies.

Development of the Connecticut Airway Risk Evaluation (CARE) system to improve handoff communication in pediatric patients with tracheotomy.

National attention has focused on the importance of handoffs in medicine. Our practice during airway patient handoffs is to communicate a patient-specific emergency plan for airway reestablishment; patients who are not intubatable by standard means are at higher risk for failure. There is currently no standard classification system describing airway risk in tracheotomized patients. To introduce and assess the interrater reliability of a simple airway risk classification system, the Connecticut Airway Risk Evaluation (CARE) system. We created a novel classification system, the CARE system, based on ease of intubation and the need for ventilation: group 1, easily intubatable; group 2, intubatable with special equipment and/or maneuvers; group 3, not intubatable. A "v" was appended to any group number to indicate the need for mechanical ventilation. We performed a retrospective medical chart review of patients aged 0 to 18 years who were undergoing tracheotomy at our tertiary care pediatric hospital between January 2000 and April 2011. INTERVENTIONS Each patient's medical history, including airway disease and means of intubation, was reviewed by 4 raters. Patient airways were separately rated as CARE groups 1, 2, or 3, each group with or without a v appended, as appropriate, based on the available information. After the patients were assigned to an airway group by each of the 4 raters, the interrater reliability was calculated to determine the ease of use of the rating system. We identified complete data for 155 of 169 patients (92%), resulting in a total of 620 ratings. Based on the patient's ease of intubation, raters categorized tracheotomized patients into group 1 (70%, 432 of 620); group 2 (25%, 157 of 620); or group 3 (5%, 29 of 620), each with a v appended if appropriate. The interrater reliability was κ = 0.95. We propose an airway risk classification system for tracheotomized patients, CARE, that has high interrater reliability and is easy to use and interpret. As medical providers and national organizations place more focus on improvements in interprovider communication, the creation of an airway handoff tool is integral to improving patient safety and airway management strategies following tracheotomy complications.

Swallowing Mechanics Associated With Artificial Airways, Bolus Properties, and Penetration-Aspiration Status in Trauma Patients.

2017-09-18

Artificial airway procedures such as intubation and tracheotomy are common in the treatment of traumatic injuries, and bolus modifications may be implemented to help manage swallowing disorders. This study assessed artificial airway status, bolus properties (volume and viscosity), and the occurrence of laryngeal penetration and/or aspiration in relation to mechanical features of swallowing. Coordinates of anatomical landmarks were extracted at minimum and maximum hyolaryngeal excursion from 228 videofluoroscopic swallowing studies representing 69 traumatically injured U.S. military service members with dysphagia. Morphometric canonical variate and regression analyses examined associations between swallowing mechanics and bolus properties based on artificial airway and penetration-aspiration status. Significant differences in swallowing mechanics were detected between extubated versus tracheotomized (D = 1.32, p < .0001), extubated versus decannulated (D = 1.74, p < .0001), and decannulated versus tracheotomized (D = 1.24, p < .0001) groups per post hoc discriminant function analysis. Tracheotomy-in-situ and decannulated subgroups exhibited increased head/neck extension and posterior relocation of the larynx. Swallowing mechanics associated with (a) penetration-aspiration status and (b) bolus properties were moderately related for extubated and decannulated subgroups, but not the tracheotomized subgroup, per morphometric regression analysis. Specific differences in swallowing mechanics associated with artificial airway status and certain bolus properties may guide therapeutic intervention in trauma-based dysphagia.

Injuries due to traffic accidents are frequent in childhood, and they have high mortality and morbidity. Laryngeal injury due to a traffic accident is a rare pathology and might be missed if not suspected. Here we present a laryngeal fracture in a child after a blunt chest trauma during a traffic accident that presented with pneumomediastinum and pneumothorax. A 14-year-old girl was referred for pneumomediastinum. Her physical examination was normal except subcutaneous emphysema, edema and tenderness in the cervical area, hoarseness, facial and extremity abrasions and ecchymoses. Chest tomography revealed pneumothorax and pneumomediastinum, and cranial tomography revealed maxillofacial fractures. Upper airway damage was suspected, flexible endoscopy revealed right vocal cord paralysis and cervical tomography revealed thyroid cartilage fracture. The fracture was repaired and tracheotomy was performed. She was discharged on postoperative day 6. Facial fractures were repaired in another center. Tracheotomy was removed on postoperative day 20. Her hoarseness, although decreased, still persists. Pneumomediastinum is a rare result of a laryngeal fracture and if not suspected, the fracture can easily be missed. It should be kept in mind after blunt cervical trauma with pneumomediastinum and/or pneumothorax. Direct endoscopy and cervical tomography may be necessary for the differential diagnosis.

Aspiration in critically ill patients frequently causes severe co-morbidity. We evaluated a diagnostic protocol using routine FEES in critically ill patients at risk to develop aspiration following extubation. We instructed intensive care unit physicians on specific risk factors for and clinical signs of aspiration following extubation in critically ill patients and offered bedside FEES for such patients. Over a 45-month period, we were called to perform 913 endoscopic examinations in 553 patients. Silent aspiration or aspiration with acute symptoms (cough or gag reflex as the bolus passed into the trachea) was detected in 69.3% of all patients. Prolonged non-oral feeding via a naso-gastric tube was initiated in 49.7% of all patients. In 13.2% of patients, a percutaneous endoscopic gastrostomy was initiated as a result of FEES findings, and in 6.3% an additional tracheotomy to prevent aspiration had to be initiated. In 59 out of 258 patients (22.9%), tracheotomies were closed, and 30.7% of all 553 patients could be managed with the immediate onset of an oral diet and compensatory treatment procedures. Additional radiological examinations were not required. FEES in critically ill patients allows for a rapid evaluation of deglutition and for the immediate initiation of symptom-related rehabilitation or for an early resumption of oral feeding.

The incidence of cricoarytenoid joint fixation in case of rheumatoid arthritis is 17 to 33%. In later stages of rheumatoid arthritis, a gradual fixation of cricoarytenoid joint develops and both halves of the larynx become less movable which calls for endotracheal intubation; while total fixation of this joint demands surgical tracheotomy. Hashimoto thyroiditis can display symptoms which are difficult to distinguish from the ones present in total fixation of cricoarytenoid joint caused by rheumatoid arthritis. A 60-year-old woman in terminal stage of rheumatoid arthritis and Hashimoto thyroiditis, diagnosed after clinical and other examinations. She was treated for strident breathing with surgical tracheotomy. The microscopic examination of the larynx with the use of laryngoscopic pincers suggested the immovability of the right and very limited movability of the left arytenoid cartilage. A computerized endovideostroboscopy showed only passive vertical vibrating movements of the right vocal cord and irregular vibrations of the left vocal cord. Total fixation of the cricoarytenoid joint can be caused by many pathological processes, but so far references have shown no case of rheumatoid arthritis and Hashimoto thyroiditis. In differential diagnostics, one of many examinations is the microscopic examination of the larynx, but it is very important to determine the movability of the arytenoid cartilage with the use of appropriate instruments in total endotracheal anaesthesia while the patient is fully relaxed. Movements in cricoarytenoid joints in patients with Hashimoto thyroiditis and the same conditions are preserved.

The objective of this study was to determine the predictors of sleep quality among head and neck cancer patients 1 year after diagnosis. This was a prospective, multisite cohort study of head and neck cancer patients (N = 457). Patients were surveyed at baseline and 1 year after diagnosis. Chart audits were also conducted. The dependent variable was a self-assessed sleep score 1 year after diagnosis. The independent variables were a 1 year pain score, xerostomia, treatment received (radiation, chemotherapy, and/or surgery), presence of a feeding tube and/or tracheotomy, tumor site and stage, comorbidities, depression, smoking, problem drinking, age, and sex. Both baseline (67.1) and 1-year postdiagnosis (69.3) sleep scores were slightly lower than population means (72). Multivariate analyses showed that pain, xerostomia, depression, presence of a tracheotomy tube, comorbidities, and younger age were statistically significant predictors of poor sleep 1 year after diagnosis of head and neck cancer (P < .05). Smoking, problem drinking, and female sex were marginally significant (P < .09). Type of treatment (surgery, radiation and/or chemotherapy), primary tumor site, and cancer stage were not significantly associated with 1-year sleep scores. Many factors adversely affecting sleep in head and neck cancer patients are potentially modifiable and appear to contribute to decreased quality of life. Strategies to reduce pain, xerostomia, depression, smoking, and problem drinking may be warranted, not only for their own inherent value, but also for improvement of sleep and the enhancement of quality of life.

To analysis the causes of benign tracheal stenosis and evaluate the curative effect of intraluminal bronchoscopic treatment. 158 patients with benign tracheal stenosis in our hospital from September 2005 to September 2012 were collected to retrospectively analysis the causes and clinic features of tracheal stenosis. Interventional treatments through bronchoscopy were used to treat the benign tracheal stenosis and the curative effects were evaluated. 158 cases of benign tracheal stenosis were recruited to our study, 69.6% of them were young and middle-aged. The main causes of benign tracheal stenosis were as follows: secondary to postintubation or tracheotomy in 61.4% (97/158), tuberculosis in 16% (26/158), benign tumor in 5.1% (8/158) and other 27 cases. 94.3% patients improved in symptoms with alleviation immediately after bronchoscopic treatment, the average tracheal diameter increased form (4.22 ± 2.06) mm to (10.16 ± 2.99) mm (t = 21.48, P < 0.01), dyspnea index decreased from 2.29 ± 0.75 to 0.63 ± 0.67 (t = 19.85, P < 0.01). The recurrence rate in 1 and 3 month after interventional treatment were 38.3% and 26.8%, respectively. The cases of benign tracheal stenosis were increasing year by year. The most common cause of benign tracheal stenosis was postintubation and tracheotomy. Interventional treatments through bronchoscopy is effective in treating benign tracheal stenosis, but repeated interventional procedures may be required to maintain the favorable long-term effects.

Familial congenital bilateral vocal fold paralysis: a novel gene translocation.

2015-03-01

True vocal fold (TVF) paralysis is a common cause of neonatal stridor and airway obstruction, though bilateral TVF paralysis is seen less frequently. Rare cases of familial congenital TVF paralysis have been described with implied genetic origin, but few genetic abnormalities have been discovered to date. The purpose of this study is to describe a novel chromosomal translocation responsible for congenital bilateral TVF immobility. The charts of three patients were retrospectively reviewed: a 35 year-old woman and her two children. The mother had bilateral TVF paralysis at birth requiring tracheotomy. Her oldest child had a similar presentation at birth and also required tracheotomy, while the younger child had laryngomalacia without TVF paralysis. Standard karyotype analysis was done using samples from all three patients and the parents of the mother, to assess whether a chromosomal abnormality was responsible. Karyotype analysis revealed the same balanced translocation between chromosomes 5 and 14, t(5;14) (p15.3, q11.2) in the mother and her two daughters. No other genetic abnormalities were identified. Neither maternal grandparent had the translocation, which appeared to be a spontaneous mutation in the mother with autosomal dominant inheritance and variable penetrance. A novel chromosomal translocation was identified that appears to be responsible for familial congenital bilateral TVF paralysis. While there are other reports of genetic abnormalities responsible for this condition, we believe this is the first describing this particular translocation. Copyright © 2014 Elsevier Ireland Ltd.

Goltz-Gorlin syndrome is a rare autosomal dominant hereditary disease associated with a high rate of spontaneous mutation. Diagnosis is based on clinically defined major and minor criteria. The disease is caused by a gene mutation locating to chromosome 9q22-31. We report on a young Goltz-Gorlin syndrome patient with obstructive sleep apnea syndrome. Due to intolerance to continuous positive airway pressure (CPAP) therapy and in order to avoid a tracheotomy, we opted for an alternative therapy comprising interdisciplinary multi-level surgery.

We report obstructive sleep apnea in a 3-year-old boy with tracheomalacia secondary to tracheotomy that resolved after placement of a metallic stent in the region of tracheomalacia. The tracheal location of obstruction during sleep in this case contrasts with the usual location in the pharynx or, less often, the larynx. This case also demonstrates the utility of polysomnography in managing decannulation of tracheostomies. Citation: Muzumdar H; Nandalike K; Bent J; Arens R.

Tracheotomy is a frequent procedure in extended head and neck cancer surgery and known to be a risk factor for prolonged hospitalization. The authors hypothesized that the clinical course and delayed decannulation of patients are not only influenced by airway narrowing, but also by a compromised postoperative swallowing function. The investigators implemented a retrospective cohort study. The sample was composed of a tertiary care center patients who underwent major head and neck cancer surgery, each receiving a tracheostomy. Data collected include general clinical data as well as endoscopical evaluation of swallowing function and aspiration rate. Descriptive and bivariate statistics were computed and the P value was set at.05. The sample was composed of 96 patients with an average age of 64.2 and sex ratio of 1.4:1 (m:f). There was a strong statistically significant relation between swallowing function and timing of decannulation (P < 0.001) and duration of hospitalization (P < 0.001). Age (P = 0.55), sex (P = 0.54), tumor size (P = 0.12), general diseases (P = 0.24), distant metastases (P = 0.15), or extent of neck dissection (P = 0.15) were not significantly associated to swallowing function. Permanent cannulation was significantly correlated to a primary cancer of the soft palate or base of the tonge (P < 0.001). The results of this study confirm the importance of the evaluation of swallowing function before the removal of the tracheotomy cannula in head and neck cancer patients.

The French national health insurance reimbursement system has recently changed from a global hospital funding system to casemix-based funding. The authors studied the factors likely to influence the length of hospital stay for free flap reconstructions after surgery for cancers of the oral cavity or pharynx. Data concerning 207 oral cavity or pharynx free flap reconstructions were extracted from a prospective registration. Lengths of hospital stay were compared by an analysis of variance F test or a nonparametric Kruskal-Wallis test, and transfusion rates were compared by Chi-square test or Fisher's exact test, as appropriate. The median length of hospital stay was 24 days (range: 7-145 days). Length of hospital stay was significantly longer according to the type of flap (p<0.005), in N2-N3 patients (p<0.02), a PINI score more than 10, a 3-4 American Society of Anesthesiologists (ASA) score, the presence of a tracheotomy and in patients requiring transfusion (p<0.0001). As the nodal status, the American Society of Anesthesiologists (ASA) score of the patient, the need of tracheotomy and the type of flap cannot be corrected, the management of preoperative haemoglobin and nutritional status are the sole factors which can improve the length of hospital stay. In the context of the new casemix-based funding, this study raises the problem of harvesting of the fibula flap, management of preoperative haemoglobin and nutritional status. (c) 2009 Elsevier Ltd.

A 17-year-old man was injured in a motorcycle accident, leading to a complex cerebral contusion and hepatic injury. Approximately one month after being discharged from the hospital, the patient experienced gradually progressive dyspnea on exertion. Chest computed tomography revealed severe upper tracheal stenosis; thus, emergency tracheotomy and subsequent tracheoplasty were performed. Microscopically, the deformation of tracheal cartilage and extensive interstitial ossification/fibro-elastic changes were observed. To our knowledge, this is the first report documenting the ossification of the trachea that rapidly progressed after injury, which was confirmed by surgical resection of the upper trachea.

We present the techniques of various operations on the larynx and pharynx (incision of abscesses of the tonsils, tonsillectomy, tracheotomy, uvulectomy, and removal of foreign bodies) found in the Greek texts of Byzantine physicians. The techniques of these operations were the first to be so meticulously described and were compiled from the texts, now lost, of the ancient Greek physicians. These medical texts, which followed and enriched the Hippocratic, Hellenistic, Roman, and Galenic medical traditions, later influenced medieval European surgery, either directly through Latin translations or indirectly through works of Arab physicians.

Objective: To analyze the clinical data and summarize therapeutic experiences of cervicofacial venous malformations involving isthmus faucium area. Methods: Clinical records from 143 patients with venous malformations involving isthmus faucium area treated at our hospital between January 2012 and January 2016 were reviewed. There were 70 males and 73 females. Age ranged from 1 to 52 years old, with a median age of 14.5 years. There were 19 cases with lesions involving in only 1 subanatomic area above and 124 cases with lesions involving in more than 1 subanatomic areas, including 63 cases with lesions involving in more than 2 areas. There were 50 patients presenting with additional maxillofacial and cervical lesions. Clinical symptoms included snoring ( n =98), indistinct phonation ( n =49), and tonsil hypertrophy more than degree Ⅱ ( n =19). Tracheotomy was performed in 3 patients prior to hospitalization, contigency tracheotomy during hospitalization in 10 patients, and oral trachea cannula in other patients. All therapeutic procedures, including single chemical ablation with ethanol injection ( n =94), single lesion resection ( n =9) and both of them ( n =40), were performed under general anesthesia. Treatment remedies included mesh suture, macroglossia reduction and excision of maxillofacial and cervical lesions for patients presenting with extensive malformations extending to maxillofacial and cervical area. Tonsil resection were done in patients having tonsil venous malformations or tonsil hypertrophy more than degree II. Achauer's 4-grade criterion was applied to evaluate the treatment outcomes. SPSS 18.0 software was used to analyze the data. Results: Trachea cannula were not extubated untill 24 to 48 hours after treatment. Emergency tracheotomy was done in 2 cases after extubations because of dyspnea, and successful extubations were obtained in other cases. There were no advents of pulmonary vascular spasm or pulmonary embolism. There was significant difference between before and after operation (snore: χ(2)=105.431, ambiguous pronunciation: χ(2)=59.698, tonsil hypertrophy more than degree Ⅱ: χ(2)=33.530, all P <0.01). The patients were followed-up for 1-4 years, and there were 123 cases at grade Ⅳ (complete disappear of lesions in 62 cases without recurrence), 17 at grade Ⅲ , 3 at grade Ⅱ, and no case at gradeⅠ. Conclusions: Chemical ablation with ethanol injection for venous malformations involving isthmus faucium area is recommended, wheras combined remedies including injection, mesh suture, macroglossia reduction, and excision of cervicofacial lesions are suggested in treatment of extensive lesions extending to maxillofacial and cervical area. Tonsil resection should be done in patients having tonsil venous malformations or tonsil hypertrophy more than degree Ⅱ, which is safe and highly effective, with good reservation of function, in the treatment of maxillofacial and cervical venous malformations involving isthmus faucium area.

Background To ascertain current chest radiography practice in intensive care units (ICUs) in the Netherlands. Methods Postal survey: a questionnaire was sent to all ICUs with > 5 beds suitable for mechanical ventilation; pediatric ICUs were excluded. When an ICU performed daily-routine chest radiographs in any group of patients it was considered to be a "daily-routine chest radiography" ICU. Results From the number of ICUs responding, 63% practice a daily-routine strategy, in which chest radiographs are obtained on a daily basis without any specific reason. A daily-routine chest radiography strategy is practiced less frequently in university-affiliated ICUs (50%) as compared to other ICUs (68%), as well as in larger ICUs (> 20 beds, 50%) as compared to smaller ICUs (< 20 beds, 65%) (P > 0.05). Remarkably, physicians that practice a daily-routine strategy consider daily-routine radiographs helpful in guiding daily practice in less than 30% of all performed radiographs. Chest radiographs are considered essential for verification of the position of invasive devices (81%) and for diagnosing pneumothorax, pneumonia or acute respiratory distress syndrome (82%, 74% and 69%, respectively). On demand chest radiographs are obtained after introduction of thoracic drains, central venous lines and endotracheal tubes in 98%, 84% and 75% of responding ICUs, respectively. Chest films are also obtained in case of ventilatory deterioration (49% of responding ICUs), and after cardiopulmonary resuscitation (59%), tracheotomy (58%) and mini-tracheotomy (23%). Conclusion There is notable lack of consensus on chest radiography practice in the Netherlands. This survey suggests that a large number of intensivists may doubt the value of daily-routine chest radiography, but still practice a daily-routine strategy. PMID:16848892

Serial office-based steroid injections for treatment of idiopathic subglottic stenosis.

Current treatment options for idiopathic subglottic stenosis include endoscopic interventions, resection, and tracheotomy. Recently, serial office-based steroid injections were proposed as an alternative that may stabilize or induce regression of airway stenosis without the need for repeated operations. Procedure completion rate, pain, complications, effect on stenosis, time since the last operation, and limitations have not been described. Retrospective case series. Retrospective series of 19 patients undergoing serial office-based steroid injection for idiopathic subglottic stenosis. Outcome measures included completion rate, procedure-related pain scores, complications, percentage of airway stenosis, and time since the last operative intervention. Procedure completion rate was 98.8%. Average pain score during the procedure was 2.3 ± 1.7 on a 10-point scale. There were no immediate complications. One patient underwent awake tracheotomy 8 days after her second injection and was later decannulated. Average stenosis decreased from 35% ± 15% to 25% ± 15% (n = 16; P = .086) over the first of three injections and 40% ± 15% to 25% ± 10% to 20% ± 10% (n = 8; P = .002) for those patients completing two sets of three injections. Fourteen of 17 patients undergoing at least three injections have not returned to the operating room since the first injection. Office-based steroid injection represents a promising new treatment pathway for a disease that requires long-term management, offering a purely pharmacologic approach to a disorder that has traditionally been approached from a mechanical perspective. It is safe, well tolerated, and effective. Furthermore, it may help patients and physicians avoid repeated trips to the operating room and the associated risks. 4.

Objective: To evaluate the feasibility and efficacy of the integrallty submucosal resection of adult-onset laryngeal papilloma by CO 2 laser. Methods: A group of 64 cases (36 males and 28 females, multipe lesions 54 cases and single lesion 10 cases, aged 18-75 years, mean age 43.13 years) with adult-onset laryngeal papilloma encountered in the first affliated hospital of Sun Yatsen university from 2009 to 2015 was retrospectively analyzed. All cases were treated with integrallty submucosal dissection of the tumor by CO 2 laser, and observed the changes of tumor integral scope, inter-operative, operative processes, postoperative voice quality, postoperative scarring, and the tracheotomy conditions, which were analysed and evaluated. Results: A total of 64 patients were followed up from 1 year to 5 years. Preoperative tumor integral scope of these patients averaged of 7.00. A total of 62 cases kept 0 score of the tumor integral scope for at least one year, which lead to a clinical cure rate of 96.9%. The inter-operative averaged of 25.7 months. The total operative processes of these patients were 87 times (mean time 1.36). Four cases resulted in postoperative scarring. However these was a good result in postoperative voice quality with a mean score 4.25. As to the changes of tumor integral scope, all cases got a declining score (mean score 6.72), which resulted in a remission rate of 100%. Conclusion: The integrallty submucosal dissection of adult-onset 1aryngeal papilloma by CO 2 laser was an effective way to reduce the tumor integral scope; lengthen their inter-operative; decrease the operative processes, avoid the occurrence of tracheotomy; and improve the postoperative voice quality. Most of the patients could even be cured ultimately.

To provide preliminary clinical data regarding endoscopically placed nitinol stents for children with tracheal obstruction as a temporizing measure to allow for trach tube decannulation while awaiting growth to allow for tracheal resection. This case series describes the experiences of two children (ages 5 and 15) who were dependent upon tracheotomy because of acquired tracheal obstruction. Both patients had combined tracheomalacia and tracheal stenosis. After failing tracheoplasty with rib graft augmentation both patients suffered from extensive tracheal disease, which was too long to allow for immediate tracheal resection. Endoscopic placement of nitinol stents in the obstructed tracheal segment using fluoroscopic guidance. All tracheotomy tubes were removed immediately after successful stent deployment with the patient still under general anesthesia. Four stents were placed in total. The first patient's initial stent was too narrow and was, therefore, removed and replaced at a later date with a larger diameter stent. The second patient experienced distal migration of his initial stent requiring stent removal and replacement at a later date. Both patients remain successfully decannulated (follow-up, 25 and 26 months) and are currently living more normal lives as they grow and await tracheal resection. Preliminary use of nitinol stents for pediatric tracheal obstruction has enabled successful decannulation in two children with complicated airways. Our results with this series of patients suggest that nitinol stents can be safely used in children as a temporizing measure until tracheal resection can be safely performed. With this approach children can live free from the hassles of trach care, social isolation and peer ridicule. Limited pediatric experience exists in the literature about nitinol stents. Thus, our experience with stent selection and placement will help others avoid problems encountered in this initial series. Copyright 2002 Elsevier Science Ireland Ltd.

Application of Electrocautery Needle Knife Combined with Balloon Dilatation versus Balloon Dilatation in the Treatment of Tracheal Fibrotic Scar Stenosis.

Electrocautery needle knives can largely reduce scar and granulation tissue hyperplasia and play an important role in treating patients with benign stricture. The aim of this retrospective study was to evaluate the efficacy and safety of electrocautery needle knife combined with balloon dilatation versus balloon dilatation alone in the treatment of tracheal stenosis caused by tracheal intubation or tracheotomy. We retrospectively analysed the clinical data of 43 patients with tracheal stenosis caused by tracheotomy or tracheal intubation in our department from January 2013 to January 2016. Among these 43 patients, 23 had simple web-like stenosis and 20 had complex steno sis. All patients were treated under general anaesthesia, and the treatment methods were (1) balloon dilatation alone, (2) needle knife excision of fibrotic tissue combined with balloon dilatation, and (3) needle knife radial incision of fibrotic tissue combined with balloon dilatation. After treatment the symptoms, such as shortness of breath, were markedly improved immediately in all cases. The stenosis degree of patients who were treated with the elec-trocautery needle knife combined with balloon dilatation had better improvement compared with that of those treated with balloon dilatation treatment alone after 3 months (0.45 ± 0.04 vs. 0.67 ± 0.05, p < 0.01), and the proportion of restenosis occurrence that required further treatment was decreased at 6 months (46.9 vs. 81.8%), especially for the web-like stenosis patients, as most of their stenoses dilated with no obvious restenosis and achieved clinical cure. Electrocautery needle knife combined with balloon dilatation is an effective and safe treatment for tracheal fibrotic stenosis compared with balloon dilatation alone. © 2017 S. Karger AG, Basel.

19th century pioneers of intensive therapy in North America. Part 2: Joseph O'Dwyer.

Dr Joseph O'Dwyer's principal distinction lies in his dedication and achievements in battling laryngeal diphtheria among children at the New York Foundling Asylum, where he was a physician from 1872. He was also active at the Presbyterian Hospital of New York and in private practice. Some of his pioneering work anticipated methods of intensive care medicine. His achievements included: * Introduction of a practical system of intralaryngeal intubation, including designs of tubes and a technique for inserting them, after many years of careful study and experimentation - always "without borrowed inspiration". * Use of his tubes in children with diphtheritic pseudomembranes in the larynx, to substantially increase their survival chances at a time when tracheotomy for this problem still had a high failure rate. The first intubated patient recovered, November 1882, only after change to prolonged wearing of a tracheotomy tube, so O'Dwyer did not date his first intubation success until 21 May 1884. * Introduction of his tubes into the Fell method of forced respiration, with the resultant Fell-O'Dwyer apparatus supplying practical instrumentation for intermittent positive pressure ventilation. * Demonstration that this apparatus, primarily used for saving lives after acute opiate poisoning, was also useful with some intracranial disasters, 1894. * Provision of a system, which others then applied, enabling surgeons to overcome the great "pneumothorax problem" of intrathoracic operations, and thereby conduct safe surgery inside the chest, 1898. * Development of an intubating method using successive short-term dilatations for treating chronic laryngeal stenosis, usually syphilitic, in adults, 1885. Throughout his medical lifetime, O'Dwyer was held in the highest regard as an altruistic, compassionate person of "sincere simplicity and frank goodness of character".

To compare intra-operative and post-operative effectiveness of fiber delivered CO 2 laser to monopolar electrocautery in robot assisted tongue base surgery. Prospective non-randomized clinical study. Twenty moderate to severe obstructive sleep apnea (OSA) patients, non-compliant with Continuous Positive Airway Pressure (CPAP), underwent Transoral Robotic Surgery (TORS) using the Da Vinci surgical robot in our University Hospital. OSA was treated with monopolar electrocautery in 10 patients, and with flexible CO 2 laser fiber in another 10 patients. The following parameters in the two sets are analyzed: Intraoperative bleeding that required cauterization, robot operating time, need for tracheotomy, postoperative self-limiting bleeding, length of hospitalization, duration until start of oral intake, pre-operative and post-operative minimum arterial oxygen saturation, pre-operative and post-operative Epworth Sleepiness Scale score, postoperative airway complication and postoperative pain. Mean follow-up was 12 months. None of the patients required tracheotomy and there were no intraoperative complications related to the use of the robot or the CO 2 laser. The use of CO 2 laser in TORS-assisted tongue base surgery resulted in less intraoperative bleeding that required cauterization, shorter robot operating time, shorter length of hospitalization, shorter duration until start of oral intake and less postoperative pain, when compared to electrocautery. Postoperative apnea-hypopnea index scores showed better efficacy of CO 2 laser than electrocautery. Comparison of postoperative airway complication rates and Epworth sleepiness scale scores were found to be statistically insignificant between the two groups. The use of CO 2 laser in robot assisted tongue base surgery has various intraoperative and post-operative advantages when compared to monopolar electrocautery.

We evaluated late intensive care unit admission in liver transplant recipients to identify incidences and causes of acute respiratory failure in the postoperative period and to compare these results with results in patients who did not have acute respiratory failure. We retrospectively screened the data of 173 consecutive adult liver transplant recipients from January 2005 through March 2015 to identify patients with late admission (> 30 d posttransplant) to an intensive care unit. Patients were divided into 2 groups: patients with and without acute respiratory failure. Acute respiratory failure was defined as severe dyspnea, respiratory distress, decreased oxygen saturation, hypoxemia or hypercapnia on room air, or need for noninvasive or invasive mechanical ventilation. Demographic, laboratory, clinical, and respiratory data were collected. Model for End-Stage Liver Disease, Acute Physiology and Chronic Health Evaluation II, and Sequential Organ Failure Assessment scores; lengths of intensive care unit and hospital stays; and hospital mortality were assessed. Among 173 patients, 37 (21.4%) were admitted to an intensive care unit, including 22 (59.5%) with acute respiratory failure. The leading cause of acute respiratory failure was pneumonia (n = 19, 86.4%). Patients with acute respiratory failure had significantly lower levels of albumin before intensive care unit admission (P = .003). In patients with acute respiratory failure, severe sepsis and septic shock were more frequently observed and tracheotomy was more frequently performed (P = .041). Acute respiratory failure developed in 59.5% of liver transplant recipients with late intensive care unit admission. The leading cause was pneumonia, with this group of patients having higher requirements for invasive mechanical ventilation and tracheotomy, longer stays in an intensive care unit, and higher mortality.

Only two cases of juvenile xanthogranuloma of the larynx have been previously reported in the literature. We report a new case, which occurred in an 18-month-old girl. The patient was brought to us for treatment of stridor and respiratory distress. During examination, she was found to have a subglottic mass. The lesion was treated with laser microlaryngoscopy, which relieved the patient's respiratory distress and obviated the need for tracheotomy. Pathologic examination of the mass revealed that it was consistent with a juvenile xanthogranuloma. Juvenile xanthogranuloma is generally a benign and self-limiting disease, but complications can occur when the space that the tumor occupies causes functional impairment.

Hereditary angioedema is a rare familial disease caused by the defect of complement C1esterase inhibitor (C1-INH). It is characterized by recurrent acute edema of the extremities, the face, the respiratory tract and the gastrointestinal tract. Acute laryngeal edema usually produces laryngeal obstruction. Two cases have been treated since 1986, one of them had been admitted for forty-five times because of recurrent acute laryngeal edema. Investigations showed two families with a high incidence of this disease. Laboratory examination showed a remarkable decrease of C1-INH and C4. Tracheotomy is indicated in patients with laryngeal edema. Great success was achieved in two patients treated with danazol.

Pycnodysostosis is an autosomal recessive disorder due to a mutation in the cathepsin K gene, which causes a decrease of the bone turnover; a review of the literature suggests that pycnodysostosis is frequently associated with severe respiratory obstruction, which needs surgical treatment. The aim of this paper is to describe the surgical treatment of a 3½-year-old girl affected by Pycnodysostosis complicated by a severe sleep-related respiratory disorder. The surgical treatment, consisting of adenotonsillectomy and palatoplasty, resulted in a striking amelioration of respiratory parameters and increased posterior airway space, and allowed the patient to avoid tracheotomy while awaiting for maxillo-mandibular surgery. © 2014 Wiley Periodicals, Inc.

Neurolymphomatosis (NL) is an extremely rare disease and tracheal asphyxia due to NL has not been previously reported. A 54-year-old Chinese woman with a history of diffuse large B-cell lymphoma in her first complete remission developed peripheral neuropathy and tracheal asphyxia. Neurolymphomatosis involving the right brachial plexus and the right vagus nerve was demonstrated by PET/CT, but not by MRI. She underwent urgent tracheotomy and impact chemotherapy using rituximab combined with high dose methotrexate and involved field radiotherapy. She achieved a second complete remission. PET/CT plays valuable role in differentiating NL from other neuropathies in patients with lymphoma. Complete remission can be achieved in NL due to large B-cell lymphoma.

Standardizing adult tracheostomy tube styles: what is the clinical and cost-effective impact?

2006-01-01

Tracheostomy tubes are made of a variety of materials, components, and styles. In a recent merger of our hospitals, we noted a large assortment of tubes available for clinicians. The different tubes resulted in complaints from staff, which included confusion, delays in obtaining preferred tubes, and inconsistent shelf stock. A multidisciplinary task force was formed to recommend standardizing the styles of tracheostomy tubes. A comparison of tracheotomy procedures, tracheostomy tube usage, and tube costs were done 6 months before and 6 months after the standardization. The number of tube styles decreased from 9 to 4; specialty extra-long tubes decreased from 3 to 2. There were no cost savings in standardizing the tracheostomy tubes.

Role of Aquaporin Water Channels in Airway Fluid Transport, Humidification, and Surface Liquid Hydration

Several aquaporin-type water channels are expressed in mammalian airways and lung: AQP1 in microvascular endothelia, AQP3 in upper airway epithelia, AQP4 in upper and lower airway epithelia, and AQP5 in alveolar epithelia. Novel quantitative methods were developed to compare airway fluid transport–related functions in wild-type mice and knockout mice deficient in these aquaporins. Lower airway humidification, measured from the moisture content of expired air during mechanical ventilation with dry air through a tracheotomy, was 54–56% efficient in wild-type mice, and reduced by only 3–4% in AQP1/AQP5 or AQP3/AQP4 double knockout mice. Upper airway humidification, measured from the moisture gained by dry air passed through the upper airways in mice breathing through a tracheotomy, decreased from 91 to 50% with increasing ventilation from 20 to 220 ml/min, and reduced by 3–5% in AQP3/AQP4 knockout mice. The depth and salt concentration of the airway surface liquid in trachea was measured in vivo using fluorescent probes and confocal and ratio imaging microscopy. Airway surface liquid depth was 45 ± 5 μm and [Na+] was 115 ± 4 mM in wild-type mice, and not significantly different in AQP3/AQP4 knockout mice. Osmotic water permeability in upper airways, measured by an in vivo instillation/sample method, was reduced by ∼40% by AQP3/AQP4 deletion. In doing these measurements, we discovered a novel amiloride-sensitive isosmolar fluid absorption process in upper airways (13% in 5 min) that was not affected by aquaporin deletion. These results establish the fluid transporting properties of mouse airways, and indicate that aquaporins play at most a minor role in airway humidification, ASL hydration, and isosmolar fluid absorption.

Chronic critical illness is a devastating syndrome for which treatment offers limited clinical benefit but imposes heavy burdens on patients, families, clinicians, and the health care system. We studied the availability of advance directives and appropriate surrogates to guide decisions about life-sustaining treatment for the chronically critically ill and the extent and timing of treatment limitation. Prospective cohort study. Respiratory Care Unit (RCU) in a large, tertiary, urban, university-affiliated, hospital. Two hundred three chronically critically ill adults transferred to RCU after tracheotomy for failure to wean from mechanical ventilation in the intensive care unit. None. We interviewed RCU caregivers and reviewed patient records to identify proxy appointments, living wills, or oral statements of treatment preferences, resuscitation directives, and withholding/withdrawal of mechanical ventilation, nutrition, hydration, renal replacement and vasopressors. Forty-three of 203 patients (21.2%) appointed a proxy and 33 (16.2%) expressed preferences in advance directives. Do not resuscitate directives were given for 71 patients (35.0%). Treatment was limited for 39 patients (19.2%). Variables significantly associated with treatment limitation were proxy appointment prior to study entry (time of tracheotomy/RCU transfer) (odds ratio = 6.7, 95% confidence interval [CI], 2.3-20.0, p = 0.0006) and palliative care consultation in the RCU (OR = 40.9, 95% CI, 13.1-127.4, p < 0.0001). Median (interquartile range) time to first treatment limitation was 39 (31.0-45.0) days after hospital admission and 13 (8.0-29.0) days after RCU admission. For patients dying after treatment limitation, median time from first limitation to death ranged from 3 days for mechanical ventilation and hydration to 7 days for renal replacement. Most chronically critically ill patients fail to designate a surrogate decision-maker or express preferences regarding life-sustaining treatments. Despite burdensome symptoms and poor outcomes, limitation of such treatments was rare and occurred late, when patients were near death. Opportunities exist to improve communication and decision-making in chronic critical illness.

Williams-Beuren syndrome is a rare neurodevelopmental disorder caused by deletion of 1.5-1.8Mb genes on chromosome 7q11.23. The syndrome was first described as a triad of supra-valvular aortic stenosis, mental retardation, and distinctive facial features. Our patient was referred due to audible inspiratory stridor when he was seven days old. Following endoscopy he was diagnosed with bilateral vocal cord paralysis and was eventually intubated due to respiratory de-compensation followed by tracheotomy. On further workup he was diagnosed with hypothyroidism. Genetic workup supported the diagnosis of Williams-Beuren syndrome. We report here a case with an unusual clinical presentation.

We report two 45 year old men with Duchenne muscular dystrophy. Case 1 showed a deleted exon 50 of the dystrophin gene by MLPA analysis, and Case 2 showed deleted exons 46-52. Both patients presented with severe weakness of the skeletal muscles and respiratory dysfunction, while cardiac involvement was mild and cognitive function was almost normal. The patients are able to shop at a mall, participate in activities, and attend hobbies, although they are bedridden with artificial respiration through tracheotomy. With the progress of the respiratory care and cardiac protective therapy, the prognosis of Duchenne muscular dystrophy has improved remarkably. At present, it is possible to survive over 40 years with maintenance of quality of life, if cardiac damage is not severe.

[Transoral laser resection for head and neck cancers].

PubMed

Hartl, Dana

2007-12-01

Transoral laser surgery has become a therapeutic option and even a standard for certain tumors of the larynx and pharynx. The postoperative course after this type of minimally invasive surgery has been shown to be significantly simpler, with less need for temporary tracheotomy and enteral feeding. For selected tumors amenable to this approach, the oncologic results have been shown to be equivalent to those obtained by classic external approaches. Transoral laser surgery requires specific equipment and training of the surgeon, the anaesthesiologist, the operating room team and the pathologist. Despite this specificity, but because of the simplified postoperative course, transoral laser surgery has already supplanted several external approaches and will in the future probably replace other techniques, as experience with the technique increases and the indications evolve.

2005-06-07

Tracheal malignancies are usual victim of delay in diagnosis by virtue of their symptoms resembling asthma. Sometimes delayed diagnosis may lead to almost total airway obstruction. For difficult airways, not leaving any possibility of manipulation into neck region or endoscopic intervention, femorofemoral cardiopulmonary bypass can be a promising approach. We are presenting a case of tracheal adenoid cystic carcinoma (cylindroma) occupying about 90% of the tracheal lumen. It was successfully managed by surgical excision of mass by sternotomy and tracheotomy under femorofemoral cardiopulmonary bypass (CPB). Any patient with recurrent respiratory symptoms should be evaluated by radiological and endoscopic means earlier to avoid delay in diagnosis of such conditions. Femorofemoral cardiopulmonary bypass is a relatively safe way of managing certain airway obstructions.

The left wing of a whooping crane (Grus americana) was amputated for treatment of severe nonunion and malunion fractures of the radius and ulna. During the postoperative convalescent period, the bird aspirated a corn kernel and subsequently suffered episodic bouts of dyspnea. The bird was anesthetized with tiletamine-zolazepam. Attempts to deliver the kernel through the glottis with endoscopic instruments were unsuccessful. The corn kernel was retrieved via a tracheotomy incision. Endoscopy of the trachea 2 mo postoperatively showed complete healing of the tracheal incision. Mucosal integrity had been reestablished, and tracheal lumen diameter was not compromised. The bird continues in good health 2.5 yr after surgery, shows no sign of respiratory disease, and currently is in a captive breeding program.

The use of intravenous thrombolytic agents has revolutionised the treatment of acute myocardial infarction. However, the improvement in mortality rate achieved with these drugs is tempered by the risk of serious bleeding complications, including intracranial haemorrhage. Tenecteplase is a genetically engineered mutant tissue plasminogen activator. Haemorrhagic complications of tissue plasminogen activator (tPA) are well known. Compared to other tPAs, tenecteplase use leads to lower rates of bleeding complications. Here, we report a case of unusual site of spontaneous bleeding, intralingual haematoma during tenecteplase therapy following acute myocardial infarction, which caused significant upper airway obstruction and required tracheotomy to maintain the patient's airway. Clinical dilemmas related to securing the airway or reversing the effects of tissue plasminogen activator are discussed. PMID:23862086

Surgical management of congenital saccular cysts of the larynx.

PubMed

Ward, R F; Jones, J; Arnold, J A

1995-09-01

Congenital saccular cysts of the larynx are unusual lesions that commonly present with respiratory obstruction in infants and children. The saccular cyst may result from an atresia of the laryngeal saccule orifice or may represent the retention of mucus in the collecting ducts of submucosal glands located around the ventricle. Traditionally, the treatment of the lesions has been endoscopic unroofing or marsupialization. Frequently, this modality requires multiple procedures as well as concomitant tracheotomy. There also have been reports of acquired subglottic stenosis. We have found that removal of the recurrent saccular cyst can be achieved relatively safely and effectively via a lateral cervical approach to the thyrohyoid membrane. We review our experience with four patients with congenital saccular cysts and detail the evaluation and surgical management of these lesions.

Since the outbreak of West Nile virus (WNV) in the United States in 1999, the WNV neuroinvasive disease has been increasingly reported with a wide spectrum of neuromuscular manifestations. We submit a case of a 46-year-old male with a history of alcohol abuse, diabetes, hypertension, and hepatitis C who presented with fever, nausea, shortness of breath, and dysphagia. The patient rapidly developed hypercapnic respiratory failure and was found to have WNV meningoencephalitis without obvious neuromuscular weakness. His hospital course was significant for repeated failures of extubation secondary to persistent bulbar weakness eventually requiring tracheotomy. This is a unique case of WNV meningoencephalitis with bulbar palsy without other neuromuscular manifestations resulting in recurrent hypercapnic respiratory failure. © The Author(s) 2015.

To assess the efficacy of recombinant human erythropoietin (rhEPO) in amyotrophic lateral sclerosis (ALS). Patients with probable laboratory-supported, probable or definite ALS were enrolled by 25 Italian centres and randomly assigned (1:1) to receive intravenous rhEPO 40,000 IU or placebo fortnightly as add-on treatment to riluzole 100 mg daily for 12 months. The primary composite outcome was survival, tracheotomy or >23 h non-invasive ventilation (NIV). Secondary outcomes were ALSFRS-R, slow vital capacity (sVC) and quality of life (ALSAQ-40) decline. Tolerability was evaluated analysing adverse events (AEs) causing withdrawal. The randomisation sequence was computer-generated by blocks, stratified by centre, disease severity (ALSFRS-R cut-off score of 33) and onset (spinal or bulbar). The main outcome analysis was performed in all randomised patients and by intention-to-treat for the entire population and patients stratified by severity and onset. The study is registered, EudraCT 2009-016066-91. We randomly assigned 208 patients, of whom 5 (1 rhEPO and 4 placebo) withdrew consent and 3 (placebo) became ineligible (retinal thrombosis, respiratory insufficiency, SOD1 mutation) before receiving treatment; 103 receiving rhEPO and 97 placebo were eligible for analysis. At 12 months, the annualised rate of death (rhEPO 0.11, 95% CI 0.06 to 0.20; placebo: 0.08, CI 0.04 to 0.17), tracheotomy or >23 h NIV (rhEPO 0.16, CI 0.10 to 0.27; placebo 0.18, CI 0.11 to 0.30) did not differ between groups, also after stratification by onset and ALSFRS-R at baseline. Withdrawal due to AE was 16.5% in rhEPO and 8.3% in placebo. No differences were found for secondary outcomes. RhEPO 40,000 IU fortnightly did not change the course of ALS.

1993-07-01

Narrowing of the trachea due to tracheomalacia or compression can lead to life-threatening asphyxia and may require tracheotomy with intubation or endoscopic introduction of a stent. The use of a self-expanding elastic metal prosthesis in 4 patients with airway obstruction has proved a satisfactory alternative to conventional plastic prostheses, both in the acute phase and over a long period of time. After 4 weeks total epithelium cover of the stent could be demonstrated; biopsies after 3 and 4 months showed differentiation into respiratory ciliated epithelium. Patient acceptance was excellent since there was no sensation of a foreign body, retention of secretions or cough. The physical properties of the wall stent made it a suitable mechanical replacement for an unstable or narrowed trachea during the period of observation.

The ideal laser produces discrete wounds in a reproducible manner. The CO2 laser with its 10.6 micron wavelength is highly absorbed by water, its energy concentrated at the point of impact and the longer wavelength creates less scatter in tissue. The development of binocular endoscopic delivery system for use with binocular microlaryngoscopes have aided in using CO2 laser to treat patients with subglottic and tracheal stenosis. Often, patients with these disease processes require multiple endoscopic or open reconstructive procedures and my ultimately become tracheotomy dependent. The canine model of subglottic stenosis that has been develop allows testing of new agents as adjuncts to laser treatment. Mitomycin-C is an antibiotic with antitumor activity used in chemotherapy and also in ophthalmologic surgery due to its known inhibition of fibroblast proliferation. Current studies indicate this drug to have significant potential for improving our current management of this disease process.

Beneath the different reasons for cervical masses, a spontaneous hemorrhage presents a rare and life-threatening condition. We present the rare case of a 62-year-old man who was presented with a dramatically enlarging cervical mass causing respiratory distress because of upper airway compression. An endotracheal intubation was lifesaving and avoided tracheotomy. A CT scan revealed a hematoma in the region of the left external carotid artery. An emergency angiography embolized a ruptured branch of the superior thyroid artery and surgery evacuated the hematoma. We discuss the rarity of the condition, reasons for a spontaneous rupture of the artery, and the diagnostic and treatment strategy. In addition, we review the literature on spontaneous thyroid artery hemorrhages, which, up to now, have been described only for the inferior thyroid artery. We conclude that the optimal management for cases of cervical hematoma is intubation, diagnosis, and angiography before surgery.

Conversion disorder is a condition in which psychological stress in response to difficult situations manifests as physical symptoms. Here, we report a case of postoperative coma due to conversion disorder in an elderly oral cancer patient. An 82-year-old woman was referred to Tokyo Dental College Chiba Hospital with a mass lesion on the tongue. A biopsy revealed a well-differentiated squamous cell carcinoma. Surgical treatment was performed for the tongue carcinoma and tracheotomy for management of the airway. On postoperative day 5, the patient exhibited loss of consciousness (Glasgow Coma Scale: E1, VT, M1; Japan Coma Scale: III-300). The patient's vital signs were all normal, as were the results of a full blood count, brain-CT, MRI, and MRA. Only the arm dropping test was positive. Therefore, the cause of the coma was diagnosed as conversion disorder. Seven hours later, the patient showed a complete recovery.

2015-07-01

Exogenous lipoid pneumonia (ELP) is a rare (incidence 1.0%-2.5%), often under-diagnosed disease, caused by the aspiration and accumulation of exogenous lipids within the pulmonary alveoli. Various cases have been described due to inhalation of lubricants via the nasal passages and oropharynx, aspiration of mineral oils in laxatives in patients with eating disorders, application of lip gloss, occupational exposure to liquid paraffin or mineral oils ("fire-eaters", industrial use in washing of machinery, automobile workshops, plastic paints, etc.) and application of Vaseline during the insertion of nasogastric tubes and in the care of tracheotomy patients. ELP usually presents radiologically as areas of low-attenuation peribronchial consolidation and ground glass opacities, with a predominantly bibasal distribution. We present 5 cases of long-standing laryngectomy patients diagnosed with ELP who admitted using Vaseline in their tracheal stoma care. Copyright © 2014 SEPAR. Published by Elsevier Espana.

Haddock, Nicholas T; DeLacure, Mark D; Saadeh, Pierre B

2008-07-01

The vertical rectus abdominus myocutaneous (VRAM) flap is a valuable option for tongue reconstruction. However, the traditional inset (skin to remaining oral mucosa) obviates a more anatomic reconstruction. Eight patients underwent total or subtotal glossectomy with VRAM reconstruction. The muscle inset was supported at the inferior mandibular border attached to the remaining lingual mucosa or gingiva. The neotongue, consisting of skin and subcutaneous fat, was sutured posteriorly to the remaining tongue base, and the other surfaces were trimmed and left unsutured. Reconstruction was successful in all patients. The neotongue assumed palatal configuration, and within 2 weeks uniform granulation tissue followed by mucosalization occurred. One year postoperatively, all patients tolerated ad lib diets, spoke intelligibly, were gastrostomy tube and tracheotomy free and had no evidence of aspiration. This neotongue sits on the mandible under voluntary control, permitting effective obturation against the hard palate and providing successful speech and swallowing.

Coagulation disorders and an immune-altered state are common among total artificial heart patients. In this context, we sought to evaluate the safety of percutaneous dilatational tracheostomy in cases of prolonged need for mechanical ventilatory support. We retrospectively analysed the charts of 11 total artificial heart patients who received percutaneous dilatational tracheostomy. We focused on early and late complications. We observed no major complications and no procedure-related deaths. Early minor complications included venous oozing (45.4%) and one case of local infection. Late complications, including subglottic stenosis, stomal infection or infections of the lower respiratory tract, were not observed. In conclusion, percutaneous dilatational tracheostomy in total artificial heart patients is safe. Considering the well-known benefits of early tracheotomy over prolonged translaryngeal intubation, we advocate early timing of therapy in cases of prolonged mechanical ventilation. © The Author 2015.

2016-06-01

Sarcopenic dysphagia is characterized by the loss of swallowing muscle mass and function associated with generalized loss of skeletal muscle mass and function. In this report, the authors describe a patient with possible sarcopenic dysphagia after lung cancer surgery and was treated subsequently by rehabilitation nutrition. A 71-year-old man with lung cancer experienced complications of an acute myocardial infarction and pneumonia after surgery. He was ventilated artificially, and a tracheotomy was performed. The patient received diagnoses of malnutrition, severe sarcopenia, and possible sarcopenic dysphagia. His dysphagia was improved by a combination of dysphagia rehabilitation including physical and speech therapy and an improvement in nutrition initiated by a nutrition support team. Finally, he no longer had dysphagia and malnutrition. Sarcopenic dysphagia should be considered in patients with sarcopenia and dysphagia. Rehabilitation nutrition using a combination of both rehabilitation and nutritional care management is presumptively useful for treating sarcopenic dysphagia.

We report a case of persistent bilateral vocal cord paralysis which developed after spine surgery under general anesthesia in a patient with multiple system atrophy. A 64-year-old woman was scheduled to receive spinal fusion surgery for kyphoscoliosis. She did not have apparent symptoms of vocal cord paralysis such as hoarseness before surgery. The surgery was performed smoothly under general anesthesia with endotracheal intubation. However, immediately after extubation, the patient developed severe upper airway obstruction and was re-intubated. Fiberoptic laryngoscopy revealed bilateral vocal cord abductor paralysis. Vocal cord paralysis did not improve and she received tracheotomy on the 12th day after surgery. She also showed symptoms of autonomic nervous system dysfunction and cerebellar ataxia, and was diagnosed as multiple system atrophy on postoperative day 64. We discuss differential diagnosis of persistent vocal cord paralysis after general anesthesia, and anesthetic management of a patient with multiple system atrophy.

A modification of the Bjork flap in tracheostomies for head and neck cancer patients.

PubMed

Stathopoulos, P; Stassen, L

The etymology of the word tracheotomy derives from two Ancient Greek words: the word trachea (Greek τραχɛία tracheía) and the word stoma (Greek στóμα stóma) meaning "mouth," and refers to the making of an opening. It is believed that an early tracheostomy was performed by the Greek physician Asclepiades of Bithynia, in order to treat upper airway obstruction. A secure airway in the intraoperative and early postoperative period is of paramount importance for a number patients undergoing head and neck cancer surgery. We describe a modification of the Bjork flap used in tracheostomies for head and neck cancer patients, which allows tracheal outline reconstitution and significantly decreases the risk of respiratory obstruction and clinically evident tracheal stenosis, as our results have shown, at least five years after the last patient was discharged.

The involvement of the thyroid by tuberculosis (TB) is rare. Hypothyroidism caused by tissue destruction is an extremely rare report. Our aim was to report a patient with primary thyroid TB emphasizing the importance of diagnosis, despite the rarity of the occurrence. Women, 62 years old, showing extensive cervical mass since four months, referring lack of appetite, weight loss, dysphagia and dysphonia. Laboratorial investigation revealed primary hypothyroidism. Cervical ultrasound: expansive lesion in left thyroid lobe, involving adjacent muscle. Computed tomography scan: 13 cm diameter cervical mass with central necrosis. Fine needle biopsy: hemorrhagic material. total thyroidectomy, left radical neck dissection and protective tracheotomy. The pathological examination showed chronic granulomatous inflammatory process with areas of caseous necrosis and lymph node involvement. The thyroid baciloscopy was positive. Pulmonary disease was absent. The patient was treated with antituberculosis drugs. Thyroid TB is not frequent, and should be considered as differential diagnosis of hypothyroidism and anterior cervical mass.

The aim of this study was to investigate the factors associated with infection at the recipient site of pectoralis major myocutaneous flap (PMMF) of head and neck cancer patients. We retrospectively reviewed head and neck cancer patients who underwent PMMF reconstruction and identified those with recipient site infection. Variables of patients with and without infection were compared and associated factors were investigated by logistic regression model. A total of 478 patients were included in the final analysis and 183 patients (38.3%) developed recipient site infection. Lower margin of skin island, concurrent tracheotomy, diabetes mellitus, mandibular plate reconstruction, prior radiation, and peri-operative blood transfusion were independent factors associated with recipient site infection of PMMF. Skin island of PMMF beyond the eighth intercostal space markedly increased the risk of recipient site infection after major head and neck cancer surgery. Recognition of relevant factors associated with infection may help surgeons to identify those at risk.

We report a child with vocal cord adhesion encountered during induction of anesthesia. A 4-month-old girl was scheduled for bilateral lip plasty. She was intubated for one week due to pneumonia at the age of 3 days. Hoarseness and stridor appeared just after extubation. Although laryngo-fiberoptic examination had been tried several times, otorhinologists could not find any abnormality. We once decided to postpone the operation because of severe stridor. However, laryngofiberoptic examination could not reveal any abnormality, and we rescheduled the operation. Tracheal intubation using laryngoscope was not possible due to vocal cord adhesion. Finally, 2.5 mm ID tracheal tube was intubated by using a fiberscope, and lip plasty was performed. The patient stayed in the ICU for 7 days after surgery. Tracheotomy was performed 3 weeks after the operation. We should pay attention to stridor in an infant before general anesthesia, since it suggests severe airway narrowing although laryngo-fiberoptic examination could not find any abnormalities.

Vocal cord paralysis in children.

King, Ericka F; Blumin, Joel H

Vocal fold paralysis (VFP) is an increasingly commonly identified problem in the pediatric patient. Diagnostic and management techniques honed in adult laryngologic practice have been successfully applied to children. Iatrogenic causes, including cardiothoracic procedures, remain a common cause of unilateral VFP. Neurologic disorders predominate in the cause of bilateral VFP. Diagnosis with electromyography is currently being evaluated in children. Treatment of VFP is centered around symptomology, which is commonly divided between voice and airway concerns. Speech therapy shows promise in older children. Surgical management for unilateral VFP with injection laryngoplasty is commonly performed and well tolerated. Laryngeal reinnervation is currently being applied to the pediatric population as a permanent treatment and offers several advantages over laryngeal framework procedures. For bilateral VFP, tracheotomy is still commonly performed. Glottic dilation procedures are performed both openly and endoscopically with a high degree of success. VFP is a well recognized problem in pediatric patients with disordered voice and breathing. Some patients will spontaneously recover their laryngeal function. For those who do not, a variety of reliable techniques are available for rehabilitative treatment.

Robots have invaded industry and, more recently, the field of medicine. Following the development of various prototypes, Intuitive Surgical® has developed the Da Vinci surgical robot. This robot, designed for abdominal surgery, has been widely used in urology since 2000. The many advantages of this transoral robotic surgery (TORS) are described in this article. Its disadvantages are essentially its high cost and the absence of tactile feedback. The first feasibility studies in head and neck cancer, conducted in animals, dummies and cadavers, were performed in 2005, followed by the first publications in patients in 2006. The first series including more than 20 patients treated by TORS demonstrated the feasibility for the following sites: oropharynx, supraglottic larynx and hypopharynx. However, these studies did not validate the oncological results of the TORS technique. TORS decreases the number of tracheotomies, and allows more rapid swallowing rehabilitation and a shorter length of hospital stay. Technical improvements are expected. Smaller, more ergonomic, new generation robots, therefore more adapted to the head and neck, will probably be available in the future. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

Heimlich's maneuver-assisted bronchoscopic removal of airway foreign body

Solanki, Sohan Lal; Bansal, Shivendu; Khare, Arvind; Jain, Amit

2011-01-01

Aspiration of foreign bodies (FBs) by children can lead to serious illness and sometimes even death. Bronchoscopic removal of the FB is necessary to prevent from any catastrophic event. Sometimes bronchoscopic removal is not possible due to the larger size of the FB, sharp FB, or long duration FB. Tracheostomy is normally used for the removal of such FBs. The aim of this case report is to highlight the use of Heimlich maneuver for the removal of such FBs before opting invasive procedures. In the present case, a 5-year-old child was presented with history of FB aspiration 5 h back. After multiple failed bronchoscopic attempts to remove the FB it was decided to use Heimlich maneuver in the supine position. A single attempt of Heimlich maneuver expelled the FB into the oral cavity, which was removed by Magill's forceps. On repeated bronchoscope check, there was no remnant of FB. Child's further course of stay in hospital was uneventful. In conclusion, Heimlich maneuver may be useful in patient with failed bronchoscope removal of airway FBs before proceeding for tracheotomy or other invasive procedures. PMID:25885389

A 1-day-old male infant was referred to our department for evaluation of multiple malformations in his oral cavity. He was diagnosed duplication of the pituitary gland-plus syndrome with epignathus, cleft palate, duplication of the mandible, and a lobulated tongue. A thumb-sized mass lesion was visible on the hard palate. The duplicated mandible and lower lip was fused at the midline. The alveolar ridge was protruding through a wide-cleft soft palate involving the uvula. Further examination showed a lobulated tongue, which was seen behind the duplicated part of the mandible. Five days after birth, tracheotomy and epignathus resection were performed. At 7 months of age, the excess tissue of the duplicated mandible was resected at the area of adhesion on the lingual side, and the duplicated tongue and lip were reconstructed. A palatoplasty was performed at 20 months of age. Thereafter, the patient's progress was uneventful, with no abnormality in swallowing. No recurrence of epignathus has been observed during 2 years of follow-up.

This study aimed to clarify the energy requirement in patients with amyotrophic lateral sclerosis (ALS) undergoing tracheostomy positive pressure ventilation with tracheostomy. Total energy expenditure (TEE) was measured in 10 hospitalized bedridden ALS patients using the doubly-labeled water (DLW) method. The mean TEE/day and TEE/fat- free mass estimated by DLW method were 934 ± 201 kcal/day and 34.8 ± 5.5 kcal/kg/day, respectively. The mean TEE/resting metabolic rate (RMR) was 0.85 when RMR was estimated by the Harris-Benedict equation, 0.91 by Dietary Reference Intake (DRI), and 0.97 by Ganpule's equation using fat-free mass (FFM). The ratios of TEE to measured RMR were 1.05, 1.15 and 1.23 in three patients. In conclusion, multiplying measured RMR by 1.1 to 1.2 is considered to be appropriate to estimate energy need. However, because it is difficult to measure RMR directly in a clinical setting, an appropriate equation for estimating RMR for ALS patient should be developed.

A major obstacle to lung transplantation and combined heart- lung transplantation is dehiscence of the tracheobronchial anastomosis. We explored the possibility of laser welded anastomoses in canine tracheas in vivo. Laser anastomoses were performed on three-quarter circumferential anterior tracheotomies. A continous wave diode laser (808 +1 nm) at a power density of 9.6 watts/cm was used. Human fibrinogen was mixed with indocyanine green dye (ICG, max absorbance 805 nm) and applied to the anastomosis site prior to laser exposure. Animals were sacrificed at 0, 21 and 28 days post-operatively. At sacrifice weld bursting pressures were measured by raising intratracheal pressure using forced ventilation via an endotracheal tube. Sutured and laser welded anastomoses had similar bursting pressures, and exhibited satisfactory histologic evidence of healing. However, compared to polypropylene sutured controls, the laser welded anastomoses exhibited less peritracheal inflammatory reaction and showed visibly smoother luminal surfaces at 21 and 28 days post- operatively. Tracheal anastomosis using ICG dye enhanced fibrinogen combined with the near-infrared diode laser is a promising extension of the technology of laser tissue fusion and deserves further study.

A database was developed for prospective, longitudinal study of recurrent respiratory papillomatosis (RRP) in a large population of pediatric patients. Data recorded for each patient included epidemiological factors, human papilloma virus (HPV) type, clinical course, staged severity of disease at each surgical intervention, and frequency of surgical intervention. The study hypothesizes that patients with HPV type 11 (HPV-11) and patients younger than 3 years of age at diagnosis are at risk for more aggressive and extensive disease. The 10-year prospective epidemiological study used disease staging for each patient with an original scoring system. Severity scores were updated at each surgical procedure. Parents of children with RRP referred to the authors' hospital completed a detailed epidemiological questionnaire at the initial visit or at the first return visit after the study began. At the first endoscopic debridement after study enrollment, tissue was obtained and submitted for HPV typing using polymerase chain reaction techniques and in situ hybridization. Staging of disease severity was performed in real time at each endoscopic procedure using an RRP scoring system developed by one of the authors (B.J.W.). The frequency of endoscopic operative debridement was recorded for each patient. Information in the database was analyzed to identify statistically significant relationships between extent of disease and/or HPV type, patient age at diagnosis, and selected epidemiological factors. The study may represent the first longitudinal prospective analysis of a large pediatric RRP population. Fifty-eight of the 73 patients in the study underwent HPV typing. Patients infected with HPV-11 were significantly more likely to have higher severity scores, require more frequent surgical intervention, and require adjuvant therapy to control disease progression. In addition, patients with HPV-11 RRP were significantly more likely to develop tracheal disease, to require tracheotomy, and to develop pulmonary disease. Patients receiving a diagnosis of RRP before 3 years of age had significantly higher severity scores, higher frequencies of surgical intervention, and greater likelihood of requiring adjuvant medical therapy. Patients with Medicaid insurance had significantly higher severity scores and required more frequent surgical debridement. Birth by cesarean section appeared to be a significant risk factor for more severe disease and necessity of more frequent surgical intervention. Statistical analysis of the relationships among epidemiological factors, HPV type, and clinical course revealed that patients with HPV-11 and patients younger than 3 years of age at RRP diagnosis are prone to develop more aggressive disease as represented by higher severity scores at endoscopic debridement, more frequent operative debridement procedures per year, a greater requirement for adjuvant therapy, and greater likelihood of tracheal disease with tracheotomy.

Introduction Radiotherapy or chemoradiotherapy can result in severe swallowing disorders with potential risk for aspiration and can negatively impact the patient's quality of life (QOL). Objective To assess swallowing-related QOL in patients who underwent radiotherapy/chemoradiotherapy for head and neck cancer. Methods We interviewed 110 patients (85 men and 25 women) who had undergone exclusive radiotherapy (25.5%) or concomitant chemoradiotherapy (74.5%) from 6 to 12 months before the study. The Quality of Life in Swallowing Disorders (SWAL-QOL) questionnaire was employed to evaluate dysphagia-related QOL. Results The QOL was reduced in all domains for all patients. The scores were worse among men. There was a relationship between oral cavity as the primary cancer site and the fatigue domain and also between advanced cancer stage and the impact of food selection, communication, and social function domains. Chemoradiotherapy association, the presence of nasogastric tube and tracheotomy, and the persistence of alcoholism and smoking had also a negative effect on the QOL. Conclusions According to the SWAL-QOL questionnaire, the dysphagia-related impact on QOL was observed 6 to 12 months after the treatment ended. PMID:25992151

With improved survival, more AIDS patients, especially heavy smokers and alcohol abusers, may be confronted with laryngeal squamous cell carcinoma. Since curative treatment may require aggressive combined therapy, these patients, often suffering from immunosupression and poor general condition, present unique therapeutic challenges. The objective of the study was to describe treatment dilemmas. This case report presents a detailed description of an AIDS patient with carcinoma of the larynx. A patient with T3N0M0 laryngeal carcinoma and AIDS underwent tracheotomy and biopsy, followed by severe neck and pulmonary infection. After convalescence, radiotherapy was administered, with no evidence of a disease during a 3.5-year follow-up. During his remaining life, the patient developed severe psychoaffective disorder, his immune state deteriorated until he demised from sepsis. In conclusion, patients with HIV infection, especially having a history of tobacco or alcohol abuse, should be carefully examined for head and neck carcinoma that is likely to be more aggressive. Following surgery, AIDS patients may have worse wound healing and a greater tendency to contract infections. Radiotherapy and especially chemotherapy may cause life-threatening complications. Although early detection may increase survival, curative treatment should involve many disciplines and extra caution.

We report the case of a 2-year-old boy who experienced total asphyxia at 4 months of age, and suffered abnormalities at specific phases of the respiratory cycle. The patient was bedridden due to severe tetraplegia and showed little response to external stimuli. He has been tube-fed since the initial asphyxia and a tracheotomy was performed after recurrent hypoxic episodes as a result of the respiratory dysfunction. Upon examination, his respiratory pattern was characterized by arrest during the inspiratory phase with a possible over-riding secondary inspiration. The respiratory pause at the inspiratory phase was markedly prolonged during an episode of pulmonary infection, resulting in recurrent cyanosis that necessitated artificial ventilation. The "second" inspiration typically occurred during the mid- or late-inspiratory phases, with this pattern often shown to be variable after epileptic seizures. The characteristic breathing of this patient suggested that difficulty in forming a normal respiratory cycle, other than during periods of hypoventilation or apnoea, could be a significant respiratory dysfunction following asphyxiation. Strategies for the management of such patients should be carefully designed after close observation of breathing patterns within the respiratory cycle, and with consideration for the influence of epileptic seizures and other inputs from somatic afferents.

The use of a stapler for pharyngeal closure during total laryngectomy was first described in 1971. It provides rapid watertight closure without surgical field contamination. The objective of our study was to compare the incidence of pharyngocutaneous fistula after total laryngectomy with manual and mechanical closures of the pharynx. This was a non-randomised, prospective clinical study conducted at two tertiary medical centres from 1996 to 2011 including consecutive patients with laryngeal tumours who underwent total laryngectomy. We compared the incidence of pharyngocutaneous fistula between two groups of patients: in 20 patients, 75 mm linear stapler closure was applied, whereas in 67 patients a manual suture was used. Clinical data were compared between groups. The groups were statistically similar in terms of gender, age, diabetes mellitus, smoking and alcohol consumption and tumour site. The group of patients who underwent stapler-assisted pharyngeal closure had a higher number of patients with previous tracheotomy (p < 0.001) and previous chemoradiation (p < 0.001). The incidence of pharyngocutaneous fistula was 30% in the mechanical closure group and 20.9% in the manual suture group (p = 0.42). In conclusion the use of the stapler does not increase the rate of fistulae.

Tracheostomy is a mainstay modality for airway management for patients with head-neck cancer undergoing surgery. This study aims to define factors predicting need of tracheostomy and define an effective objective criterion to predict tracheostomy need. 486 patients undergoing composite resections were studied. Factors analyzed were age, previous surgery, extent of surgery, trismus, extent of mandibular resection and reconstruction etc. Factors were divided into major and minor, using the clinical assessment scoring system for tracheostomy (CASST) criterion. Sixty seven (13.7%) patients required tracheostomy for their peri-operative management. Elective tracheostomies were done in 53 cases during surgery and post-operatively in 14 patients. All patients in whom tracheostomies were anticipated had a score of seven or more. A decision on whether or not an elective tracheotomy in head and neck surgery is necessary and can be facilitated using CASST criterion, which has a sensitivity of 95.5% and a negative predictive value (NPV) of 99.3%. It may reduce post-operative complications and contribute to safer treatment. Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

2009-03-01

Two previous articles in this series have described the reintroduction of forced respiration for ventilatory difficulties, particularly in opiate poisoning (by George Fell), and successful use of intralaryngeal tubes designed for treating airway obstruction in diphtheritic acute laryngitis (by Joseph O'Dwyer). In 1891, O'Dwyer extended the applications of Fell's system, introducing a longer orolaryngeal tube, replacing Fell's methods of inflating the lungs, which had been with a somewhat unsatisfactory facemask or through a tracheotomy tube. The combined system became known as the "Fell-O'Dwyer apparatus". Use of the apparatus widened, to include treating apnoea from intracranial disasters (by William P Northrup, especially) and, on the initiative of Rudolph Matas, in delivering anaesthesia and maintaining lung inflation to enable intrathoracic surgery (by FW Parham). Although the apparatus was used beyond New York (eg, in New Orleans by J D Bloom, especially for neonatal apnoea), it is difficult to find other than nonspecific references. Matas and Bloom improved O'Dwyer's original system, but after the clinical success of Charles Elsberg's continuous insufflation anaesthesia for thoracic surgery, 1909, American anaesthetists came to prefer that.

To develop strategies that may assist the surgeon to prevent and manage severe bleeding complications after adenoidectomy and tonsillectomy. Retrospective. Expert reports for malpractice lawsuits or professional boards were reviewed. The review was restricted to "deaths" and "permanent generalized neurological deficiencies." Forty-three cases matched our search criteria, including 32 deaths. Adenoidectomy cases (2) were associated with immediate bleeding because of direct vascular injury resulting in one death. Tonsillectomy cases were associated with delayed and repeated episodes of bleeding resulting in 31 deaths, including 19 children. Autopsy verified predominantly aspiration and vascular injuries. An apallic syndrome prevailed in surviving patients. Careful inspection of the nasopharynx immediately before adenoidectomy and curettage in a piecemeal fashion under visual control is helpful to prevent direct injury to aberrant arteries. Tonsillectomy cases are associated with delayed and episodic bleeding with spontaneous cessation and young age. Inpatient observation should be strongly considered in cases with repeated bleeding episodes to provide immediate treatment. The follow-up should be focused on disturbed wound healing. Outcome appears to be dependent on adequate airway management. Rigid instruments and tracheotomy in case of intubation failure are highly recommended to facilitate airway protection and ventilation.

Rapid resolution of fetal goiter associated with maternal Grave's disease: a case report.

The incidence of abnormal fetal thyroid function with maternal Grave's disease is about 2-12%. The development of larger fetal goiters can complicate labor and precipitate life-threatening airway obstruction at delivery. A case is presented of a large stable goiter confirmed by sonography, which unexpectedly resolved by the time of parturition. A 3 x 6 cm fetal goiter was detected at 34 weeks gestation in a mother treated with propylthiouracil for Grave's disease. A repeat sonogram at 36 weeks showed no change in goiter size. Umbilical blood sampling showed the fetus to be markedly hyperthyroid. Planned Cesarean section took place 11 days after the final sonogram. A multi-disciplinary operative team was present including the Otolaryngology service with equipment for emergency intubation, bronchoscopy and tracheotomy. Upon delivery, the infant had no evidence of goiter and no airway compromise. Fetal goiter is a rare entity, and recent advances in the field of maternal-fetal medicine have enabled intra-uterine diagnosis and treatment of such conditions. A review of published case reports demonstrates two trends in treated fetuses: preterm progressive resolution of the goiter, or delivery with gross evidence of goiter. This reported case is unique, as a persistent goiter resolved completely in less than 2 weeks. Otolaryngologic response to and management of potential congenital airway compromise is discussed.

Vocal cord paralysis after tracheal intubation is rare. It causes severe hoarseness and aspiration, and delays recovery and discharge. Arytenoid cartilage dislocation and recurrent nerve paralysis are main causes of vocal cord paralysis. Physical stimulation of the tracheal tube as well as patient and surgical characteristics also contribute. Vocal cord paralysis occurs in 1 (0.07%) of 1,500 general surgery patients and on the left side in 70% of cases. It is associated with surgery/anesthesia time (two-fold, 3-6 hours; 15-fold, over 6 hours), age (three-fold, over 50 years), and diabetes mellitus or hypertension (two-fold). Symptoms resolve in 2-3 months. In adult cardiovascular surgery, vocal cord paralysis occurs in 1 (0.7-2%) of 50-100 cardiac surgery patients and 1 (8.6-32%) of 3-10 thoracic aortic surgery patients. In pediatric cardiac surgery, vocal cord paralysis occurs in 1 (0.1-0.5%) of 200-1,000 patients. We classified the severity of vocal cord paralysis as I, severe hoarseness; II, aspiration or dysphagia; and III, bilateral vocal cord paralysis, aspiration pneumonia, or the need for tracheal re-intubation or tracheotomy. We discuss the importance of informed consent for the patient and family.

Aim: To summary the experience for prevention and treatment of recurrent laryngeal nerve (RLN) injury in thyroid surgery. Methods: Clinical features of 623 patients who received thyroid surgery from January 2010 to December 2012 were analyzed retrospectively, and the features of RLN injury and intraoperative as well as postoperative treatments were reviewed. Results: RLN injury occurred in 31 patients (4.98%), in which, unilateral RLN injury occurred in 27 patients and bilateral RLN injuries occurred in 4 patients (temporary injury in 28 patients and permanent injury in 3 patients). 6 patients underwent RLN anastomosis during surgery and exhibited transient hoarseness after surgery. RLN exploration and decompression was given in 1 patient and the patient got normal vocal cord motion 2 months after surgery. 1 patient with bilateral injuries received tracheotomy and CO2 laser resection of arytenoid cartilage and achieved recovery 1 year later. Conclusions: In order to prevent RLN injury, the anatomic variations of RLN should be mastered. Routine exposure of RLN can effectively prevent the injury in patients receiving the second or multiple surgeries. Early interventions for RLN injury include mainly early discovery, early exploration and early anastomosis, and the function of RLN in some patients can recover completely. Subsequent treatments mainly focus on the improvement of the voice, expansion of glottis and melioration of dyspnea. PMID:24482694

Objective The treatment of laryngotracheal stenosis is a major therapeutic challenge. Various treatments include observation, medical management, and surgical management. The most effective surgical management is resection and reconstruction. To the authors’ knowledge, no reports have described the use of xenogenic acellular dermal matrix (ADM) for laryngotracheal stenosis. Methods A 27-year-old man presented with hemoptysis of the neck due to a traffic accident. Emergency orotracheal intubation was performed. Tracheostomy was then performed under local anesthesia. Computed tomography revealed fractures of the right thyroid cartilage and posterior arc of the cricoid cartilage and stenosis of the subglottis and first and second tracheal rings. We used a composite hyoid–sternohyoid osseomuscular flap with xenogenic ADM and a straight silicone tube as a lumen stent to reconstruct the laryngotracheal stenosis. Results Surgical recovery was uneventful. The tracheotomy opening was changed to a metal tube 5 days postoperatively. Four months postoperatively, the silicone tube was endoscopically removed under local anesthesia. The patient was decannulated 20 days later. The patient satisfied with his voice, respiration, and deglutition at the 16-month postoperative follow-up. Conclusion The use of ADM for laryngotracheal stenosis may reduce the growth of granulation tissues and promote the repair process. PMID:28480810

Objective The treatment of laryngotracheal stenosis is a major therapeutic challenge. Various treatments include observation, medical management, and surgical management. The most effective surgical management is resection and reconstruction.

[Ventilatory dysfunction in motor neuron disease: when and how to act?].

Amyotrophic lateral sclerosis is a devastating progressive neurodegenerative disorder, involving motor neurons in the cerebral cortex, brainstem and spinal cord. Mean duration of survival from the time of diagnosis is around 15 months, being pulmonary complications and respiratory failure responsible for more than 85% of deaths. Albeit the inevitability of respiratory failure and short-term death, standardized intervention protocols have been shown to significantly delay the need for invasive ventilatory support, thus prolonging survival and enhancing quality of life. The authors present an intervention protocol based on clinical progression and respiratory parameters. Decisions regarding initiation of non-invasive positive pressure ventilation (NIPPV) and mechanically assisted coughing, depend on development of symptoms of hypoventilation and on objective deterioration of respiratory parameters especially in what concerns bulbar muscle function. These include maximum inspiratory capacity (MIC), difference between MIC and vital capacity (MIC-VC), and assisted peak cough flow (PCF). These standardized protocols along with patient and caregivers education, allow for improved quality of life, prolonged survival and delay or eventually prevent the need for tracheotomy and invasive ventilatory support. Supplemental oxygen should be avoided in these patients, since it precludes use of oxymetry as feedback for titrating NIPPV and MAC, and is associated with decreased ventilatory drive and aggravated hypercapnia.

Kenny Caffey syndrome (KCS) is a rare syndrome reported almost exclusively in Middle Eastern populations. It is characterized by severe growth retardation—short stature, dysmorphic features, episodic hypocalcaemia, hypoparathyroidism, seizures, and medullary stenosis of long bones with thickened cortices. We report a 10-year-old boy with KCS with an unusually severe respiratory and gastrointestinal system involvement—features not previously described in the literature. He had severe psychomotor retardation and regressed developmentally from walking unaided to sitting with support. MRI brain showed bilateral hippocampal sclerosis, marked supra-tentorial volume loss and numerous calcifications. A 12 bp deletion of exon 2 of tubulin-specific chaperone E (TBCE) gene was identified and the diagnosis of KCS was confirmed. Hypercarbia following a sleep study warranted nocturnal continuous positive airway pressure (CPAP) when aged 6. When boy aged 8, persistent hypercarbia with increasing oxygen requirement and increased frequency and severity of lower respiratory tract infections led to progressive respiratory failure. He became fully dependent on non-invasive ventilation and by 9 years he had a tracheotomy and was established on long-term ventilation. He developed retching, vomiting and diarrhea. Chest CT showed changes consistent with chronic aspiration, but no interstitial pulmonary fibrosis. He died aged 10 from respiratory complications. PMID:26029652

2017-12-01

Neuromuscular diseases include a wide range of conditions that may involve potentially life-threatening respiratory complications (infection, respiratory failure). For patients with neuromuscular diseases, clinical assessment of respiratory function and regular pulmonary function tests are needed to screen for nocturnal respiratory disorders, weakness of the diaphragm and potential restrictive disorders and/or chronic hypercapnic respiratory insufficiency, possibly with couch deficiency. MANAGEMENT OF NOCTURNAL RESPIRATORY DISORDERS AND CHRONIC RESPIRATORY FAILURE: Nocturnal respiratory assistance is an important phase of care for nocturnal respiratory disorders and chronic respiratory failure. This may involve continuous positive airway pressure, adaptative servo-ventilation or non-invasive ventilation with a facial or nasal mask. As needed, diurnal assistance may be proposed by mouthpiece ventilation. Should non-invasive ventilation prove insufficient, or if significant swallowing disorders or recurrent bronchial obstruction develop, or in case of prolonged intubation, tracheotomy may be required. In case of lower airway infection with ineffective cough, physical therapy, associated with air stacking, intermittent positive pressure breathing or mechanical in-exsufflation may be proposed. Care for swallowing disorders, nutritional counseling (cachexia, obesity), vaccinations and therapeutic education are integral elements of patient-centered management aiming to prevent the negative impact of infection and to manage respiratory failure of chronic neuromuscular disease.

Observations on a set of Greco-Roman eye, ear, nose, and throat surgical instruments.

PubMed

Dedo, Herbert H

2017-02-01

The tools described in this article are verified to be Greco-Roman medical and surgical instruments for the eye, ear, nose, and throat. They include three myrtle leaf-shaped scalpels, three ear spoons, a "Q-tip," a forceps, a needle, and two arrow-pointed scalpels. One of the arrow-pointed scalpels is nearly identical to a Juerger keratome, suggesting that in Roman times, cataracts were extracted, not just "couched" into the posterior chamber. The description presented here goes beyond traditional archeological claims, because as a head and neck surgeon, I evaluated these instruments from a surgeon's point of view. For example, nonsurgeon medical historians have claimed the myrtle leaf-shaped items were used as handles or for blunt dissection, which I feel is mistaken. Review of the literature reveals the Greco-Roman surgeons were doing tonsillectomies, tracheotomies, and cataract extractions, and recognized that swimming in dirty water could cause ear infection. However, it is clear that with poor or no anesthesia, the pain from blunt dissection would have been intolerable, and unnecessary tissue planes would have been opened increasing wound infection risks. Therefore, there would have been no need for the myrtle leaf-shaped blade if it were just a handle.

Laryngeal dislocation after ventral fusion of the cervical spine

2013-01-01

We report on a 70-year-old patient who underwent ventral fusion of the cervical spine (C3/4 and C4/5) for spinal canal stenosis performed by the neurosurgery department. The patient suffered an exceedingly rare complication of the surgery – laryngeal dislocation. Had the deformed laryngeal structures been overlooked and the patient extubated as usual after surgery, reintubation would have been impossible due to the associated swelling, which might have had disastrous consequences. Leftward dislocation of the larynx became apparent post-operatively, but prior to extubation. Extubation was therefore postponed and a subsequent computed tomography (CT) scan revealed entrapment of laryngeal structures within the osteosynthesis. A trial of repositioning using microlaryngoscopy performed by otolaryngology (ears, nose and throat) specialists failed, making open surgical revision necessary. At surgery, the entrapped laryngeal tissue was successfully mobilised. Laryngeal oedema developed despite prompt repositioning; thus, necessitating tracheotomy and long-term ventilation. Laryngeal dislocation may be an unusual cause of post-operative neck swelling after anterior cervical spine surgery and should be considered in the differential diagnosis if surgical site haematoma and other causes have been ruled out. Imaging studies including CT of the neck may be needed before extubation to confirm the suspicion and should be promptly obtained to facilitate specific treatment. PMID:23983289

Impact of a viral respiratory epidemic on the practice of medicine and rehabilitation: severe acute respiratory syndrome.

PubMed

Lim, Peter A; Ng, Yee Sien; Tay, Boon Keng

2004-08-01

Severe acute respiratory syndrome (SARS) is a new respiratory viral epidemic that originated in China but has affected many parts of the world, with devastating impact on economies and the practice of medicine and rehabilitation. A novel coronavirus has been implicated, with transmission through respiratory droplets. Rehabilitation was significantly affected by SARS, because strict infection control measures run counter to principles such as multidisciplinary interactions, patients encouraging and learning from each other, and close physical contact during therapy. Immunocompromised patients who may silently carry SARS are common in rehabilitation and include those with renal failure, diabetes, and cancer. Routine procedures such as management of feces and respiratory secretions (eg, airway suctioning, tracheotomy care) have been classified as high risk. Personal protection equipment presented not only a physical but also a psychologic barrier to therapeutic human contact. Visitor restriction to decrease chances of disease transmission are particularly difficult for long-staying rehabilitation patients. At the height of the epidemic, curtailment of patient movement stopped all transfers for rehabilitation, and physiatrists had to function as general internists. Our experiences strongly suggest that rehabilitation institutions should have emergency preparedness plans because such epidemics may recur, whether as a result of nature or of bioterrorism.

Vocal cord dysfunction in a child.

Juliá, J C; Martorell, A; Armengot, M A; Lluch, R; Boluda, C F; Cerdá, J C; Alvarez, V

1999-07-01

Vocal cord dysfunction (VCD) involves paradoxical adduction of the vocal cord during the respiratory cycle. This usually occurs during inspiration, but can also be seen in expiration. Vocal cord appositioning produces airflow obstruction sufficient to cause wheezing, shortness of breath, chest tightness, and coughing. These symptoms often imitate the respiratory alterations of asthma, thus leading to inappropriate treatment; intubation or tracheotomy may prove necessary. An 11-year-old girl was admitted with intractable dyspnea. She had been diagnosed with atopic asthma, although she failed to respond to an increase in antiasthma medication, including high-dose oral steroids. Flow-volume loops were abnormal, with evidence of variable extrathoracic airway obstruction, manifested as a flat inspiratory loop. No structural abnormalities were seen with either computed tomography (CT) or magnetic resonance imaging (MRI). Fibroscopy revealed paradoxical adduction of the vocal cords during the respiratory cycle, no obstructive disorder being observed. After the diagnosis of VCD, the clinical manifestations resolved with psychiatric treatment. Adduction was not demonstrable at repeat fibroscopy after treatment. VCD may simulate bronchial asthma; it may also be associated with that disorder, thus masking the diagnosis. It should be suspected in patients with recurrent wheezing who fail to respond to usual asthma treatment. An early diagnosis avoids unnecessary aggressive management. Treatment should consist of respiratory and phonatory exercises; psychotherapy may be useful.

Efficacy and tolerance of a new silicone stent for the treatment of benign tracheal stenosis: preliminary results.

Vergnon, J M; Costes, F; Polio, J C

2000-08-01

In inoperable patients with tracheal stenosis who are treated using silicone stents, stent migration occurs in 18.6% of cases. To decrease the migration rate, we have designed a new silicone stent with narrow central and larger distal parts. This study analyzes the stability and tolerance of this new stent. Preliminary prospective study conducted in two French university hospitals. Thirteen inoperable patients with benign complex tracheal stenosis due to intubation or tracheotomy. Tracheal stent insertion was performed under general anesthesia with a rigid bronchoscope. The patients were followed up clinically up to stent removal, which was planned at 18 months. Stent insertion or removal was very simple and did not differ from other silicone stents. No migration occurred after a mean follow-up of 22.8 months. Minimal granuloma formation occurred in only one patient (7.7%). Sputum retention remained similar to that with other silicone stents and could be improved by a smoother internal wall. Stents have been removed in seven patients after a mean duration of 19.6 months, with a complete stenosis cure in four cases. This new stent combines the excellent stability of the metallic stents and the tolerance and easy removal of straight silicone stents. This allows a prolonged use in order to obtain curative action.

To evaluate the feasibility and effectiveness of emergency endotracheal intubation (EEI) under fluoroscopy guidance for patients with acute dyspnea or asphyxia. From October 2011 to October 2014, of 1521 patients with acute dyspnea or asphyxia who required EEI in 6 departments, 43 patients who experienced intubation difficulty or failure were entered into this study. Data on technical success, procedure time, complications, and clinical outcome were collected. The pulse oxygen saturation and Hugh-Jones classification changes were analyzed. Fluoroscopy-guided EEI was technically successful in all patients. Acute dyspnea had resolved in all patients with clinical success rate 100% after the procedure. There were no serious complications during or after the procedure. The pulse oxygen saturation and Hugh-Jones classification showed significant increase after EEI (P < .05). Further treatments, including tracheal stents (n = 21), surgical resection (n = 16), palliative tracheotomy (n = 4), and bronchoscopic treatment (n = 2), were performed 1 to 72 hours after EEI. During a mean follow-up period of 13.2 months, 13 patients had died and 30 patients remained alive without dyspnea. Fluoroscopy-guided EEI is a safe and feasible procedure, and may serve as an alternative treatment option for patients when traditional EEI is unsuccessful. Copyright © 2016 Elsevier Inc.

2017-10-30

The objective of this study was to describe a patient with idiopathic supraglottic stenosis who experienced persistent disease despite multiple office-based and operative interventions, whose disease is now better controlled with scheduled serial office-based steroid injections. This is a case report and literature review. A 42-year-old female was referred for worsening supraglottic stenosis despite systemic steroids. She underwent awake tracheotomy. A thorough historical, histologic, and laboratory workup did not reveal an etiology to her stenosis. She later underwent endoscopic partial laryngectomy and was able to be decannulated. She underwent a second endoscopic partial laryngectomy two years later for worsening disease and then was managed over the next seven years with intermittent systemic steroids. Over the last year, she has undergone eight office-based steroid injections with improvement in her degree of stenosis and symptom burden. There are only four prior reported cases of idiopathic supraglottic stenosis, none of which has been managed with serial office-based steroid injections. This case report adds to the small body of literature on the management of this rare disease and proposes a new office-based treatment pathway that may help induce regression of stenosis.

A 33-year-old woman presented with an unusual subglottic bulging mass accompanied by prolonged cough and wheeze. Laryngeal endoscopy revealed a bilateral, symmetrical mass immediately below the vocal cords with marked airway obstruction. Chronic subglottic laryngitis with inflammation or another condition such as amyloidosis was initially suspected. Cervicothoracic computed tomography revealed an obvious reduction of laryngeal caliber caused by an engulfing mass extending from just under the vocal cords to the cricoid ring, which was associated with thyroid, arytenoid, and cricoid cartilage destruction. Histopathological diagnosis of a biopsy specimen collected via a tracheotomy revealed that the lesion was a cT4aN0M0 adenoid cystic carcinoma (ACC) originating from the laryngeal minor salivary glands. The patient was treated by total laryngectomy with elective bilateral neck dissection under general anesthesia. Gross inspection of resected tissue confirmed yellowish-white, solid tumor mainly circumferentially encompassing the lumina of the cricoid ring. The histopathological findings confirmed typical ACC accompanied by a predominant cribriform appearance with no evidence of lymph node metastasis. The patient remains well and free of recurrence or metastasis. We herein describe laryngeal ACC and discuss radiological images and the surgical pathology. Copyright © 2016 Elsevier Ireland Ltd.

To describe a homogeneous idiopathic subglottic stenosis (ISS) population undergoing endoscopic balloon dilation and evaluate factors affecting inter-dilation interval (IDI). Retrospective review of 37 patients. Co-morbidity prevalence versus normal population was evaluated using chi-square tests. Correlations were evaluated using Pearson product moment tests. Independent samples t tests/rank sum tests assessed differences between groups of interest. All patients were female aged 45.9 ± 15.4 years at diagnosis. Four required a tracheotomy during management. Most prevalent co-morbidity was gastroesophageal reflux disease (GERD) (64.9%; P = .036). Body mass indices (BMI) at first and most recent dilation were 29.8 and 30.8 ( P = .564). Degree of stenosis before first dilation was 53 ± 14%. Patients underwent 3.8 ± 1.8 dilations (range, 1-11). Average IDI was 635 ± 615 days (range, 49-3130 days), including 556 ± 397 days for patients receiving concomitant steroid injection and 283 ± 36 for those who did not ( P = .079). Inter-dilation interval was not correlated with BMI ( r = 0.0486; P = .802) or number of co-morbidities ( r = -0.225, P = .223). Most patients with ISS can be managed endoscopically, and IDI may be increased with steroid injection. Gastroesophageal reflux disease is a common co-morbidity. Body mass index did not change over time despite potential effects on exercise tolerance; BMI did not affect IDI. Methods to determine optimal timing for next intervention are warranted.

Postoperative pneumonia (POP) is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC) surgery. Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016. We individually traced each OC patient for a period to discharge from the hospital or 45 days after surgery, whichever occur later. The incidence of POP after major OC surgery with free flap construction or major OC surgery was 11.6% or 4.5%, respectively. Patient-related risk factors for POP were male sex, T stage, N stage, clinical stage and preoperative serum albumin level. Among the investigated procedure-related variables, incision grade, mandibulectomy, free flap reconstruction, tracheotomy, intraoperative blood loss, and the length of the operation were shown to be associated with the development of POP. Postoperative hospital stay was also significantly related to increased incidence of POP. Using a multivariable logistic regression model, we identified male sex, preoperative serum albumin level, operation time and postoperative hospital stay as independent risk factors for POP. Several perioperative risk factors can be identified that are associated with POP. At-risk oral cancer patients should be subjected to intensified postoperative pulmonary care.

Results and Complications of 1104 Surgeries for Velopharyngeal Insufficiency

PubMed Central

Hirschberg, Jenő

Velopharyngeal insufficiency (VPI) means that the velopharyngeal closure is inadequate or disturbed. VPI may be organic or functional, congenital or acquired and is caused by structural alterations or paresis. The symptoms are primarily to be found in speech (hypernasality), more rarely in swallowing and hearing. The management types are as follows: speech therapy, surgery, speech bulb, and others. Surgery is indicated if the symptoms of VPI cannot be improved by speech therapy. Among the operative methods, velopharyngoplasty constitutes the basis of the surgery. The pharyngeal flap was incorporated and survived in 98.1% of the cases, hyperrhinophony disappeared or became minimal in 90% after surgery in our material (1104 cases). The speech results seemed to be the same with superiorly or inferiorly based pharyngeal flap. The Furlow technique, push-back procedure, the sphincteroplasty, and the augmentation were indicated by us if the VP gap was less than 7 mm; these methods may also be used as secondary operation. We observed among 1104 various surgeries severe hemorrhage in 5 cases, aspiration in 2 cases, significant nasal obstruction in 68 patients, OSAS in 5 cases; tracheotomy was necessary in 2 cases. Although the complication rate is rare, it must always be considered that this is not a life-saving but a speech-correcting operation. A tailor-made superiorly based pharyngeal flap is suggested today, possibly in the age of 5 years. PMID:23724266

Positron emission tomography with 15 O-labeled gases ( 15 O-PET) is important for in vivo measurement of cerebral oxygen metabolism both in clinical and basic settings. However, there are currently no reports concerning 15 O-PET in mice. Here, we developed an 15 O-PET method applicable to mice with spontaneous respiration of 15 O-gas without a tracheotomy catheter. Sequential 15 O-PET was also performed in a mouse model of chronic cerebral hypoperfusion with bilateral common carotid artery stenosis (BCAS) induced by placement of microcoils. 15 O-gas with isoflurane was supplied to the nose of mouse with evacuation of excess 15 O-gas surrounding the body. 15 O-PET was performed on days 3, 7, 14, 21, and 28 after surgery. Cerebral blood flow (CBF), cerebral blood volume, oxygen extraction fraction (OEF), and cerebral metabolic rate of oxygen (CMRO 2 ) were calculated in whole brains. A significant decrease in CBF and compensatory increase in OEF in the BCAS group produced CMRO 2 values comparable to that of the sham group at three days post-operation. Although CBF and OEF in the BCAS group gradually recovered over the first 28 days, the CMRO 2 showed a gradual decrease to 68% of sham values at 28 days post-operation. In conclusion, we successfully developed a noninvasive 15 O-PET method for mice.

Morbidity and case fatality from rattlesnake envenomation is regionally specific because of variability in relative toxicity of the species of snake encountered. A previous report of rattlesnake envenomation in New World camelids (NWC) from the western coastal United States documented high case fatality rates and guarded prognosis for survival. To describe clinical findings, treatments, and outcome of NWC with prairie rattlesnake (Crotalus viridis viridis) envenomation in the Rocky Mountain region of the United States. Twenty-seven NWC admitted to the Colorado State University Veterinary Teaching Hospital for evaluation of acute rattlesnake envenomation between 1992 and 2012. Medical records of NWC evaluated for rattlesnake envenomation as coded by the attending clinician and identified by a database search were reviewed retrospectively. Month of admission, signalment, area of bite, clinical and clinicopathologic data, treatments, and outcome were recorded. Twenty-five llamas and 2 alpacas were admitted for envenomation. Llamas were overrepresented compared to hospital caseload. The face was the most common site of envenomation, observed in 96% of recorded cases. Presenting clinical signs included fever, tachypnea, tachycardia, and respiratory distress. Nine animals required a tracheotomy. Median hospitalization time was 3 days and overall survival rate was 69%. Case fatality rate for prairie rattlesnake envenomation in NWC was lower than that reported in the Western coastal region of the United States and similar to that reported for prairie rattlesnake envenomation in horses.

2000-01-01

The purpose of this study was to compare on the basis of up to date papers currently applied methods of the percutaneous tracheostomy (PT). There are four main PT methods by: Ciaglia, Schachner, Griggs and Fantoni. In these methods a wire is introduced into the trachea serving as a guide for special forceps or series of dilatators of increasing diameter to dilate the wall and allow cannulation of the trachea. In the literature authors found a low incidence of complications after PT. Acute complications were documented in 6-18% and late complications in 1-3% of the patients. Follow-up showed no late obstructive complications at the level of stomia and very low (0.3-0.36%) mortality risk. Translaryngeal tracheostomy (TLT) by Fantoni ensures minimal risk of complications and tissue trauma. In the TLT method through a needle inserted in to the trachea a guide wire is retrogradely pushed out of the mouth and attached to special flexible tracheostomy tube by flexible plastic cone with pointed metal tip. This device is then pulled back through larynx and outwards across the trachea and neck wall by traction on the wire. TLT can also be used in infants and children and in difficult patients in whom other techniques are riskier Review of the literature suggests that the PT can be safe and also cost-effective for properly selected patients in intensive care and other hospital units.

Bilateral vocal fold immobility: a 13 year review of etiologies, management and the utility of the Empey index.

PubMed

Brake, Maria K; Anderson, Jennifer

2015-06-26

Bilateral vocal fold immobility (BVFI) is a rare diagnosis causing dyspnea, dysphonia and dysphagia. Management depends on respiratory performance, airway patency, vocal ability, and quality-of-life priorities. The authors review the presentation, management and outcome in patients diagnosed with BVFI. The utility and efficacy of the Empey index (EI) and the Expiratory Disproportion Index (EDI) are evaluated as an objective monitoring tools for BVFI patients. A 13-year retrospective review was performed of BVFI patients at St. Michael's Hospital, University of Toronto, a tertiary referral centre for laryngology. Forty-eight patients were included; 46 presented with airway obstruction symptoms. Tracheotomy was required for airway management in 40% of patients throughout the course of their treatment, which was reduced to 19% at the end of the study period. Twenty-one patients underwent endoscopic arytenoidectomy/cordotomy. Non-operative management included continuous positive airway pressure devices. Pulmonary function testing was carried out in 29 patients. Only a portion of the BVFI patients met the defined upper airway obstruction criteria (45% EI and 52% EDI). Seven patients had complete pre- and post-operative PFTs for comparison and all seven had ratios that significantly improved post-operatively which correlated clinically. The EI and EDI have limited use in evaluating patients with who have variable upper airway obstruction, but may be helpful in monitoring within subject airway function changes.

Transoral robotic supraglottic laryngectomy is a new surgical way to perform endolaryngeal resection of supraglottic laryngeal carcinoma. The aim of this report was to present our initial experience about transoral robotic supraglottic laryngectomy for early supraglottic cancer. Subjects with early squamous cell carcinoma (T1-T2) of supraglottic region who managed using transoral robotic surgery in a tertiary referral center were included in the study. The technique of robot-assisted resection, intraoperative blood loss, mean robotic operating time, pathologic margin status, postoperative extubation, need for a tracheotomy, and length of hospitalization, complications, duration of oral nutrition, and neck dissection and radiotherapy needs were evaluated. Thirteen subjects (12 men, 1 woman) with T1-T2 supraglottic carcinoma were successfully operated on with transoral robotic surgery. In all subjects, negative margins were obtained. The mean total robotic surgery time was 31.6 (SD, 16.2) minutes (range, 20-80 minutes). Mean total blood loss was less than 40 mL. Subjects started oral nutrition with a mean of 10.8 (SD, 8.9) days (range, 4-30 days) postoperatively. The mean hospitalization was 15.4 (SD, 10.4) days (range, 7-42 days). Transoral robotic supraglottic laryngectomy with the da Vinci robotic system can be regarded as a feasible, safe, and effective technique. Although short-term results seem discouraging, long-term results are needed to evaluate the oncologic safety.

To reflect on lessons learned placing endotracheal nitinol stents in children. Case series with chart review. Tertiary care children's hospital. All children who underwent nitinol cervical tracheal stenting were included. Records were carefully reviewed for intraoperative and postoperative complications, management choices, outcomes, and factors that influenced results. Between 1999 and 2011, 7 children underwent 13 stent placements. Median follow-up was 5 years (range, 1-12 years). Six patients underwent stenting as a salvage procedure following open attempts at airway reconstruction. Four patients remain decannulated with their stent in place (median follow-up 7 years). The fifth patient had his stent removed endoscopically after 50 days because it became apparent that his obstruction was primarily laryngeal. The sixth child had his stent removed via a tracheal fissure after 14 months because of recalcitrant subglottic inflammation at the superior stent border. The seventh patient was decannulated for over 2 years but ultimately required tracheotomy replacement because of stenosis with the stent lumen. Complications included stent migration (23%), restenosis (29%), edema (29%), and granulation (57%). Endotracheal nitinol stents provide a realistic opportunity for decannulation in children for whom other options have failed but should be reserved only as a salvage procedure in severely complicated airways. Our experience has taught valuable lessons about stent indications, sizing, characteristics, and deployment, as well as means to avoid and manage their complications.

Non-invasive ventilation (NIV) or tracheotomy with invasive ventilation (TIV) are treatment options in ALS. However, a proportion of patients receiving long-term ventilation decide to have it withdrawn. The objective of this study was to analyse the clinical characteristics and palliative approaches in ALS patients withdrawing from long-term ventilation (WLTV). In a cohort study, two different palliative concepts in WLTV were studied: (1) augmented symptom control (ASC; sedation not intended) in patients with ventilator-free tolerance; (2) continuous deep sedation (CDS; sedation intended) in patients without ventilator-free tolerance. Results showed that WLTV was realised in 49 ALS patients (NIV = 13; TIV = 36). Mean daily ventilation was 23.4 h. The ALS Functional Rating Scale (ALSFRS-R) was low (5.6 of 48). Forty-one per cent of patients (n = 20) presented with ophthalmoplegia. ASC was performed in 20 patients, CDS in 29 patients. The mean time to death following disconnection was 32 (0.3-164) h during ASC and 0.3 (0.2-0.6) h in CDS. In conclusion, a low ALSFRS-R, high incidence of ophthalmoplegia and extended ventilator dependency were found before WLTV. The presence or absence of ventilator-free tolerance determined the approach to the management of symptoms, the setting for immediate end-of-life care and the course of dying in WLTV.

ARDS: challenges in patient care and frontiers in research.

This review discusses the clinical challenges associated with ventilatory support and pharmacological interventions in patients with acute respiratory distress syndrome (ARDS). In addition, it discusses current scientific challenges facing researchers when planning and performing trials of ventilatory support or pharmacological interventions in these patients.Noninvasive mechanical ventilation is used in some patients with ARDS. When intubated and mechanically ventilated, ARDS patients should be ventilated with low tidal volumes. A plateau pressure <30 cmH 2 O is recommended in all patients. It is suggested that a plateau pressure <15 cmH 2 O should be considered safe. Patient with moderate and severe ARDS should receive higher levels of positive end-expiratory pressure (PEEP). Rescue therapies include prone position and neuromuscular blocking agents. Extracorporeal support for decapneisation and oxygenation should only be considered when lung-protective ventilation is no longer possible, or in cases of refractory hypoxaemia, respectively. Tracheotomy is only recommended when prolonged mechanical ventilation is expected.Of all tested pharmacological interventions for ARDS, only treatment with steroids is considered to have benefit.Proper identification of phenotypes, known to respond differently to specific interventions, is increasingly considered important for clinical trials of interventions for ARDS. Such phenotypes could be defined based on clinical parameters, such as the arterial oxygen tension/inspiratory oxygen fraction ratio, but biological marker profiles could be more promising.

Benign cicatricial airway stenosis (BCAS) is a potentially life-threatening disease. Recurrence occurs frequently after endoscopic treatment. Paclitaxel is known to prevent restenosis, but its clinical efficacy and safety is undetermined. Therefore, in this study, we investigated the efficacy and associated complications of paclitaxel as adjuvant treatment for BCAS of different etiologies. The study cohort included 28 patients with BCAS resulting from tuberculosis, intubation, tracheotomy, and other etiologies. All patients were treated at the Department of Respiratory Diseases, Beijing Tian Tan Hospital, Capital Medical University, China, between January 2010 and August 2014. After primary treatment by balloon dilation, cryotherapy, and/or high-frequency needle-knife treatment, paclitaxel was applied to the airway mucosa at the site of stenosis using a newly developed local instillation catheter. The primary outcome measures were the therapeutic efficacy of paclitaxel as adjuvant treatment, and the incidence of complications was observed as well. According to our criteria for evaluating the clinical effects on BCAS, 24 of the 28 cases achieved durable remission, three cases had remission, and one case showed no remission. Thus, the durable remission rate was 85.7%, and the combined effective rate was 96.4%. No differences in outcomes were observed among the different BCAS etiologies (P=0.144), and few complications were observed. Our results indicated that paclitaxel as an adjuvant treatment has greater efficacy than previously reported BCAS treatment methods.

The majority of patients with Pierre Robin sequence in the subdivision Fairbairn- Robin triad (FRT), are born with glossoptosis, retro-/micrognathia and cleft or agenesis of the palate leading to feeding difficulties and airway obstruction. There is limited literature on these problems, and on methods used to address them. Community nurses in the Facial Cleft Deformity Clinic evaluate associated airway obstruction and feeding problems and devise nursing interactions to address these. This retrospective study examined the incidence of airway and feeding difficulties in the neonatal, pre-surgical period, as well as the surgical and nutritional management of these infants. Retrospective records of 215 infants with FRT were examined and data on incidence, airway and feeding difficulties and surgical and nutritional management was collected. Descriptive statistics, including average and percentage values, were compiled. The incidence of FRT amongst the cleft palate patients was 6.0%, with 37.7% of these having feeding difficulties. However, surgical interventions such as glossopexy (5.6%), distraction osteogenesis (0.9%) and tracheotomy (2.3%) for airway management were seldom required. Most of the infants who had upper airway obstruction and feeding problems were handled by means of suction and drinking plates, along with additional specific feeding aids. This reduced airway obstruction in 70.6%, and feeding problems in 62.4% of these infants. Based on this study’s finding the introduction of the suction and drinking plate and the use of specific types of feeding devices and surgical management can improve growth and development in infants with FRT.

To evaluate the results of combined multilevel surgery with transoral robotic surgery (TORS) in patients with obstructive sleep apnea/hypopnea syndrome for multilevel upper airway obstruction. Subjects who underwent combined sleep surgery via TORS were evaluated. The drug-induced sleep endoscopy was used in diagnosing the presence of level-specific upper airway collapse and to detect the type of surgery. Pre- and postoperative Apnea-hypopnea index, Epworth sleepiness scale lowest oxygen saturation, total operation time, robotic set-up time and robotic surgery time, blood loss value, and complications were recorded. Twenty five subjects were identified. All subjects underwent base of tongue (BOT) + epiglottoplasty. The tracheotomy was not performed for any patient. Overall, 72% of patients met the criteria for cure, 8% met the criteria for cure, and 20% of patients met the criteria for failure. There was a significant decrease between preoperative and postoperative Apnea-hypopnea index scores (28.7 ± 17.8 SD versus 9.4 ± 12.4, P = 0.000) and Epworth sleepiness scale scores (13.5 ± 2.8 versus 3.4 ± 1.6, P = 0.000). There was a significant increase between preoperative and postoperative ED SPO2 levels (80.7 ± 7.6 versus 82.6 ± 18.1, P = 0.001). TORS BOT, epiglottoplasty, and multilevel procedures in patients with obstructive sleep apnea/hypopnea syndrome can be regarded as feasible, safe, and effective technique.

Necrotizing fasciitis in the cervical region is a rare entity, characterized by a fulminant infection that causes extensive necrosis of the subcutaneous tissue and fascial planes, with high mortality and morbidity rates. The origin is generally odontogenic or pharyngeal, involving a mixed flora of microorganisms. Descending infection and mediastinal involvement are usually associated and are the main complications. The aim of the present study was to review the cases treated in our department and analyze diagnosis and treatment, supplementing the understanding of the disease. A retrospective study was performed on the clinical records of patients admitted to our center between January 2005 and June 2010 with diagnosis of necrotizing cervical fasciitis. Six clinical records were reviewed. The origin of the infection was mainly oropharyngeal and odontogenic, with a mixed flora of Prevotella, Peptostreptococcus and coagulase-negative Staphylococcus. All patients presented mediastinal involvement: superior mediastinitis in 4 patients and superior and postero-inferior mediastinitis in 2 cases. All patients underwent early drainage by bilateral cervicotomy with mediastinal drainage by a cervical approach in those with superior mediastinal affection, and associated thoracotomy, in a single surgical step, for postero-inferior mediastinitis. Temporary tracheotomy was performed in all cases. All received broad spectrum antibiotics, with a medium hospital stay of 37 days. There were no deaths reported. Concerning cervical necrotizing fasciitis, early diagnosis and surgical treatment associated to antibiotics and intensive medical care are essential to obtain a favorable outcome.

To identify clinical predictors of quality of life (QoL) in a head and neck cancer patient population. A convenience sample of 570 patients with upper aerodigestive tract cancers were surveyed at a tertiary care oncology clinic and Veterans Affairs otolaryngology clinic. A self-administered health survey was constructed to collect demographic, health, smoking, alcohol, depression symptom, and QoL information. Tumor site and tumor stage, clinical, and treatment data were abstracted from the patient medical records. Quality of life was assessed using the Medical Outcomes Study Short-Form 36-Item Health Survey (SF-36) and the Head and Neck QoL (HNQoL) instrument. Of the 570 eligible respondents, the presence of a feeding tube had the most negative impact on QoL, with significant decrements in 6 of the 8 SF-36 scales and all 4 HNQoL scales (P<.01). In descending order of severity, medical comorbid conditions, presence of a tracheotomy tube, chemotherapy, and neck dissection were also associated with significant (P<.05) decrements in QoL domains. Patients who took the survey more than 1 year after diagnosis had improved QoL in 7 of 12 domains. Hospital site, age, education level, sex, race, and marital status were also significant predictors of QoL. There are at least 13 demographic and clinical characteristics that are significant predictors of QoL in patients with head and neck cancer, which should be considered when treating patients and conducting QoL studies in the future.

This case report deals with the unsatisfying pain management of a 44 year old patient with cardiac arrest and subsequent cardiopulmonary resuscitation. The patient has (1) a reduced consciousness, (2) is isolated due to an infection with multi-resistant germs, (3) has a tracheotomy and (4) contractures of the muscles in fingers and hands. During nursing care he shows facial expressions and body postures that indicate pain which is insufficiently addressed. The case was processed according to the model of reflexive case report by Johns (1995) and interpreted by theoretical expertise and the change of the perspective. Therefore the following questions were answered: Which factors made the nurse who brought the case to the case deliberation feeling dissatisfied with the pain management? Insufficient pain management due to a lack of knowledge, no assessment of the state of consciousness, pain and isolation probably led to unnecessary burden of the patient, next of kin and nurses. Training, systematic pain management and multi-disciplinary case conferences might facilitate dealing with comparable complex situations of caring in the future. The present case report shows that pain can only be treated successfully if pain-triggering factors are recognized, systematically assessed and treated. An adequate external assessment of the pain situation is especially important when dealing with patients who suffer from disorders of consciousness. In complex cases, in which multiple factors influence the pain situation, interdisciplinary case conferences may help to improve the quality of pain management.

Management of the difficult airway.

PubMed

Schwartz, D E; Wiener-Kronish, J P

1991-09-01

For clinicians involved in airway management, a plan of action for dealing with the difficult airway or a failed intubation should be developed well in advance of encountering a patient in whom intubation is not routine. When difficulty is anticipated, the equipment necessary for performing a difficult intubation should be immediately available. It also is prudent to have a surgeon skilled in performing a tracheotomy and a criothyroidotomy stand by. The intubation should be attempted in the awake state, preferably using the fiberoptic bronchoscope. The more challenging situation is when the difficult airway is confronted unexpectedly. After the first failed attempt at laryngoscopy, head position should be checked and the patient ventilated with oxygen by mask. A smaller styletted tube and possibly a different laryngoscope blade should be selected for a second attempt at intubation. The fiberoptic bronchoscope and other equipment for difficult intubation should be obtained. A second attempt should then be made. If this is unsuccessful, the patient should be reoxygenated, and assistance including a skilled anesthesiologist and surgeon should be summoned. On a third attempt, traction to the tongue can be applied by an assistant, a tube changer could be used to enter the larynx, or one of the other special techniques previously described can be used. If this third attempt fails, it may be helpful to have a physician more experienced in airway management attempt intubation after oxygen has been administered to the patient. If all attempts are unsuccessful, then invasive techniques to secure the airway will have to be performed.

Laryngeal transplantation offers the potential for patients without a larynx to recover their voice, which is critical in our communication age. We report clinical and functional outcomes from a laryngotracheal transplant. Widespread adoption of this technique has been slowed due to the ethical concerns of life-long immunosuppression after a nonvital organ transplant. Our patient was already on immunosuppressive medication from prior kidney-pancreas transplantation, and therefore was not exposed to added long-term risk. We describe the unique technical advances, clinical course, and rehabilitation of this patient and the implications for future laryngeal transplantation. Case report. A laryngotracheal transplantation was performed in a 51-year-old prior kidney-pancreas transplant recipient presenting with complete laryngotracheal stenosis. Surgical modifications were made in the previously described technique related to retrieval, vascular supply, and reinnervation. This resulted in a robustly vascularized organ with well-perfused long-segment tracheal transplant and early return of motor reinnervation. A multidisciplinary approach resulted in a successful transplant without evidence of rejection to date. Postoperatively, the patient continues to rely on a tracheotomy but has had the return of an oral and nasal airway, vocalization, smell, and taste, all experienced for the first time in 11 years. We have demonstrated that our methods may result in a successful laryngotracheal transplant. We describe the preparation, surgical technique, rehabilitation, and interventions employed in achieving optimal outcomes. This report contributes valuable information on this rarely performed composite transplant. Copyright © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

Our aim was to describe the clinical evolution and needs of children with spinal muscular atrophy type I treated in a domiciliary palliative care program. We undertook a retrospective chart review of nine consecutive patients. Descriptions of the clinical and demographic profile of children with spinal muscular atrophy (SMA) type I were referred to a pediatric palliative care team (PPCT). Six males and three females were admitted to the PPCT, all before six months of age, except for one afflicted with SMA type I with respiratory distress. The median time of attention was 57 days (range 1-150). The domiciliary attention mainly consisted of respiratory care. The patient with SMA type I with respiratory distress required domiciliary mechanical ventilation by tracheotomy. In all cases, a nasogastric tube (NT) was indicated. As end-of-life care, eight required morphine to manage the dyspnea, four received it only by enteral (oral or NT) administration, and four received it first by enteral administration with continuous subcutaneous infusion (CSI) later. Three of the four patients with CSI also received benzodiazepines. While they were attended by the PPCT, none required hospital admission. All the patients died at home except for the one attended to for just one day. Domiciliary care for these patients is possible. The respiratory morbidity and its management are the main issues. Application of an NT is useful to maintain nutritional balance. Morphine administration is necessary to manage the dyspnea. Palliative sedation is not always necessary.

One lung ventilation is a commonly performed surgical procedure. Although there have been several reports showing that one-lung ventilation can cause pathophysiological alterations such as pulmonary hypoxic vasoconstriction and intrapulmonary shunting, there have been virtually no reports on the effects of one-lung ventilation on lung histology. Yorkshire pigs (11-17 kg) were anesthetized, a tracheotomy performed and a tracheal tube inserted. The chest was opened and one lung ventilation (OLV), was induced by clamping of the right main bronchus. OLV was continued for 60 min before the clamp was removed and two lung ventilation (TLV) started. TLV was continued for 30 to 60 min. Blood and lung biopsies were taken immediately before OLV, 30 min and 60 min of OLV and after restoration of TLV. Histological analyses revealed that the non-ventilated lung was totally collapsed during OLV. On reventilation, there was clear evidence of vascular congestion and alveolar wall thickening at 30 min after TLV. At 60 min of TLV, there was still vascular congestion. Serum nitrite levels (as an index of nitric oxide production) showed steady decline over the course of the experimental period, reaching a significantly low level on reventilation (compared with baseline levels before OLV). Lung MPO activity (marker of neutrophil sequestration) and serum TNFalpha levels were not raised during the entire experimental period. These results suggest that there was lung vascular injury after OLV, which was associated with reduced levels of nitric oxide production and not associated with an inflammatory response.

The aim of the present study was to evaluate whether LLLT at 830 nm is able to positively modulate trachea incisional wound healing in Sprague-Dawley rats. Tracheotomy may be associated with numerous complications. Development of excess granulation tissue represents a late complication that may lead to airway occlusion. Low-level laser therapy (LLLT) has been shown to have stimulatory effects on wound healing of different tissues. Therefore, it may be suggested that LLLT could be able to positively modulate trachea wound healing as well. Using general anesthesia, a median incision was performed from the second to the fifth tracheal cartilage ring in 24 rats. Animals were then randomly divided into sham-irradiated control and laser-treated groups. LLLT (power density: 450 mW/cm(2); total daily dose: 60 J/cm(2); irradiated area ∼1 cm(2)) treatment was performed daily during the first week after surgery. Samples for histological evaluation were removed 7 and 28 days after surgical procedure. Histological sections were stained with hematoxylin-eosin and van Gieson. Results from our investigation showed that LLLT was able to reduce granulation tissue formation and simultaneously increase new cartilage development at both evaluated time intervals. From this point of view, LLLT at 830 nm may be a valuable tool in trachea wound healing modulation. Nevertheless, further detailed research is needed to find optimal therapeutic parameters and to test these findings on other animal models.

The gold standard for the management of laryngeal squamous cell carcinoma in a previously irradiated patient is "salvage" total laryngectomy, but surgical management by partial laryngectomy can sometimes be proposed in selected patients. This study was designed to review the functional and oncological outcomes of patients treated by open partial laryngectomy for recurrent squamous cell carcinoma after failure of radiotherapy or involving previously irradiated tissues and to define prognostic criteria for the selection of patients eligible for this treatment strategy. In this retrospective study, 20 patients underwent partial laryngectomy between 2000 and 2011 for recurrence or second primary stage I or II laryngeal squamous cell carcinoma in an irradiated territory (11 vertical partial laryngectomies; 9 horizontal partial laryngectomies). The 3-year overall survival rate in patients with negative resection margins was 66%, with higher survival rates for tumours confined to the glottis, and the 2-year local control rate was 67%. Positive resection margins requiring total laryngectomy were observed in 20% of cases. The 3-year overall survival rate was 56% in these patients. Exclusive oral feeding was restored in 75% of patients after an average of 32 days. The tracheotomy tube was removed after an average of 18 days in 90% of patients. The disease-free functional larynx preservation rate was 45%. Salvage partial laryngectomy in irradiated tissues is an alternative treatment option to total laryngectomy in selected patients.

To assess the prevalence and characteristics of airway involvement in relapsing polychondritis (RP). Retrospective chart review and data analysis of RP patients seen in the Rheumatology Clinic and the Complex Airway Center at Beth Israel Deaconess Medical Center from January 2004 through February 2008. RP was diagnosed in 145 patients. Thirty-one patients had airway involvement, a prevalence of 21%. Twenty-two patients were women (70%), and they were between 11 and 61 years of age (median age, 42 years) at the time of first symptoms. Airway symptoms were the first manifestation of disease in 17 patients (54%). Dyspnea was the most common symptom in 20 patients (64%), followed by cough, stridor, and hoarseness. Airway problems included the following: subglottic stenosis (n = 8; 26%); focal and diffuse malacia (n = 15; 48%); and focal stenosis in different areas of the bronchial tree in the rest of the patients. Twelve patients (40%) required and underwent intervention including balloon dilatation, stent placement, tracheotomy, or a combination of the above with good success. The majority of patients experienced improvement in airway symptoms after intervention. One patient died during the follow-up period from the progression of airway disease. The rest of the patients continue to undergo periodic evaluation and intervention. In this largest cohort described in the English language literature, we found symptomatic airway involvement in RP to be common and at times severe. The nature of airway problems is diverse, with tracheomalacia being the most common. Airway intervention is frequently required and in experienced hands results in symptom improvement.

The efficacy and safety of intraluminal Wallstent Endoprosthesis (Boston Scientific/ Medi-Tech, Quincy, MA) placement to restore airway patency in patients with tracheal stenosis or tracheomalacia are unknown. Retrospective review in setting of tertiary, referral, and academic center. A retrospective review of 13 consecutive patients over a 2-year period who underwent transoral resection of tracheal stenosis and immediate transoral Wallstent placement. One patient had tracheomalacia. All of the patients were considered at high risk for transcervical surgery or had failed prior traditional open procedures. The average patient age was 54.2 years, with nine male and four female patients. All had Cotton/Myer stenoses (grades II to IV) with moderate to severe degrees of inspiratory stridor. Four patients were tracheotomy dependent. The length of stenosis varied from 1 to 4 cm. One patient had a 10-cm segment of tracheomalacia. At the time of writing, none of the patients has had a problem with significant migration or extrusion and most of the patients have incorporated the stent well without any short-term obstructive granulation tissue. After a mean follow-up of 15 months (range, 4-24 mo). 10 of the 12 patients with stenosis (83%) have remained free of any inspiratory noise during breathing. The one patient with tracheomalacia also has remained free of symptoms. Transoral Wallstents appear to be safe and may be a reasonable alternative in the restoration of airway patency in select patients with tracheal stenosis or tracheomalacia.

Laryngoceles are air-filled sacs which communicate with the laryngeal lumen. When filled with mucus or pus, they are called laryngomucoceles and laryngopyoceles, respectively. Transoral robotic surgery (TORS) is a new and remarkable technique that expands its usefullness in otorhinolaryngology. Conventional treatments for laryngoceles were previously performed using external approaches, with aesthetically unfavorable and less function-sparing results. Transoral laser microsurgical approaches for laryngoceles were seldom reported. It is aimed to present authors' clinical experience on laryngocele management with TORS which is a rather new technique. A retrospective patient serial. Patients were evaluated for demographic data, type of lesion, reasons for hospital admittance, complaint duration, and previous surgery. Robotic surgery panel including anesthesia time, duration of surgery, need for tracheotomy, postoperative care, follow-up, and recurrence rates were also summarized. Six men (mean age 51.7 years; range 41-62) with laryngoceles underwent successful TORS. Dyspnea and hoarseness were the main complaints. Two patients had undergone previous laryngeal surgery due to laryngeal cancer, with no recurrence of malignancy at admittance for laryngocele. Three had simple laryngocele, 2 had laryngomucocele, and 1 had laryngopyocele. No laryngoceles recurred and no complication such as dysphonia or prolonged dysphagia occurred. Transoral robotic surgery was found superior in safety, technical feasibility and curative effectiveness, when compared with classical methods, especially due to absence of skin incisions. Surgical modalities for laryngocele excision should be directed toward a curative target including cosmetic and functional success, technical achievability, and surgically curative methods. Transoral robotic surgery provided all these features.

Background: Benign cicatricial airway stenosis (BCAS) is a life-threatening disease. While there are numerous therapies, all have their defects, and stenosis can easily become recurrent. This study aimed to investigate the efficacy and complications of nonstent combination interventional therapy (NSCIT) when used for the treatment of BCAS of different causes and types. Methods: This study enrolled a cohort of patients with BCAS resulting from tuberculosis, intubation, tracheotomy, and other origins. The patients were assigned to three groups determined by their type of stenosis: Web-like stenosis, granulation stenosis, and complex stenosis, and all patients received NSCIT. The efficacy and complications of treatment in each group of patients were observed. The Chi-square test, one-factor analysis of variance (ANOVA), and the paired t-test were used to analyze different parameters. Results: The 10 patients with web-like stenosis and six patients with granulation stenosis exhibited durable remission rates of 100%. Among 41 patients with complex stenosis, 36 cases (88%) experienced remission and 29 cases (71%) experienced durable remission. When five patients with airway collapse were eliminated from the analysis, the overall remission rate was 97%. The average treatment durations for patients with web-like stenosis, granulation stenosis, and complex stenosis were 101, 21, and 110 days, respectively, and the average number of treatments was five, two, and five, respectively. Conclusions: NSCIT demonstrated good therapeutic efficacy and was associated with few complications. However, this approach was ineffective for treating patients with airway collapse or malacia.

Benign cicatricial airway stenosis (BCAS) is a life-threatening disease. While there are numerous therapies, all have their defects, and stenosis can easily become recurrent. This study aimed to investigate the efficacy and complications of nonstent combination interventional therapy (NSCIT) when used for the treatment of BCAS of different causes and types. This study enrolled a cohort of patients with BCAS resulting from tuberculosis, intubation, tracheotomy, and other origins. The patients were assigned to three groups determined by their type of stenosis: Web-like stenosis, granulation stenosis, and complex stenosis, and all patients received NSCIT. The efficacy and complications of treatment in each group of patients were observed. The Chi-square test, one-factor analysis of variance (ANOVA), and the paired t -test were used to analyze different parameters. The 10 patients with web-like stenosis and six patients with granulation stenosis exhibited durable remission rates of 100%. Among 41 patients with complex stenosis, 36 cases (88%) experienced remission and 29 cases (71%) experienced durable remission. When five patients with airway collapse were eliminated from the analysis, the overall remission rate was 97%. The average treatment durations for patients with web-like stenosis, granulation stenosis, and complex stenosis were 101, 21, and 110 days, respectively, and the average number of treatments was five, two, and five, respectively. NSCIT demonstrated good therapeutic efficacy and was associated with few complications. However, this approach was ineffective for treating patients with airway collapse or malacia.

Birth prevalence and initial treatment of Robin sequence in Germany: a prospective epidemiologic study

PubMed Central

2014-01-01

Background We conducted a monthly epidemiological survey to determine the birth prevalence of Robin sequence (RS) and the use of various therapeutic approaches for it. Methods Between August 2011 and July 2012, every pediatric department in Germany was asked to report new admissions of infants with RS to the Surveillance Unit for Rare Pediatric Diseases in Germany. RS was defined as retro- or micrognathia and at least one of the following: clinically evident upper airway obstruction including recessions, snoring or hypoxemia; glossoptosis; feeding difficulties; failure to thrive; cleft palate or RS-associated syndrome. Hospitals reporting a case were asked to return an anonymized questionnaire and discharge letter. Results Of 96 cases reported, we received detailed information on 91. Of these, 82 were included; seven were duplicates and two erroneous reports. Given 662,712 live births in Germany in 2011, the birth prevalence was 12.4 per 100,000 live births. Therapeutic approaches applied included prone positioning in 50 infants, followed by functional therapy in 47. Conventional feeding plates were used in 34 infants and the preepiglottic baton plate (PEBP) in 19. Surgical therapy such as mandibular traction was applied in 2 infants, tracheotomy in 3. Conclusion Compared to other cohort studies on RS, surgical procedures were relatively rarely used as an initial therapy for RS in Germany. This may be due to differences in phenotype or an underrecognition of upper airway obstruction in these infants. PMID:24433508

Contemporary Surgery for Obstructive Sleep Apnea Syndrome

PubMed Central

2009-01-01

Surgical treatment of obstructive sleep apnea syndrome (OSAS) has been available in some form for greater than three decades. Early management for airway obstruction during sleep relied on tracheotomy which although life saving was not well accepted by patients. In the early eighties two new forms of treatment for OSAS were developed. Surgically a technique described as a uvulopalatopharyngoplasty (UPPP) was used to treat the retropalatal region for snoring and sleep apnea. Concurrently sleep medicine developed a nasal continuous positive airway pressure (CPAP) device to manage nocturnal airway obstruction. Both of these measures were used to expand and stabilize the pharyngeal airway space during sleep. The goal for each technique was to limit or alleviate OSAS. Almost 30 yr later these two treatment modalities continue to be the mainstay of contemporary treatment. As expected, CPAP device technology improved over time along with durable goods. Surgery followed suit and additional techniques were developed to treat soft and bony structures of the entire upper airway (nose, palate and tongue base). This review will only focus on the contemporary surgical methods that have demonstrated relatively consistent positive clinical outcomes. Not all surgical and medical treatment modalities are successful or even partially successful for every patient. Advances in the treatment of OSAS are hindered by the fact that the primary etiology is still unknown. However, both medicine and surgery continue to improve diagnostic and treatment methods. Methods of diagnosis as well as treatment regimens should always include both medical and surgical collaborations so the health and quality of life of our patients can best be served. PMID:19784401

Results are presented of treatment with miconazole, orally and intravenously, in patients with paracoccidioidomycosis. Twenty-eight male patients aged from 34 to 66 years and exhibiting various clinical forms of the disease were studied. Twenty-five came from endemic areas in north east Argentina (Chaco, Formosa, Misiones, Corrientes and northern Santa Fe) and the remaining three from Paraguay. Twenty patients were engaged in agricultural work or at woodmills. single or multiple lesions were observed in 24 cases. Thirteen were suffering from infection of the larynx and in two of them a tracheotomy was necessary. Twenty-three showed pulmonary lesions on X-rays. Twelve had ganglionic lesions, eight had cutaneous lesions and one patient had osteoarthritis of the knee. One patient had hepatomegaly which was unrelated to chronic alcoholism. Fourteen patients had received previous treatments such as sulphonamides and amphotericin B (7 cases); sulphonamides (3), sulphonamides and the combination sulfamethoxazole + trimethoprim (3), and one patient had received all three medications. All patients had relapsed before starting miconazole therapy. Diagnosis was established by the presence of P. brasiliensis in all cases, recovered either from cutaneous or mucosal biopsy samples or from the sputum. Complement fixation tests were positive in all patients at the onset of the treatment and the immunodiffusion reactions showed precipitation bands in 27/28 patients. Skin tests with P. brasiliensis antigens proved to be positive in 18 cases and negative in 10. The erythrocyte sedimentation rate was markedly accelerated in 22 patients (greater than 20 mm in the first hour).(ABSTRACT TRUNCATED AT 250 WORDS) Images p24-a Fig 1 Fig 2 PMID:122643

Zika virus (transmitted by mosquitoes) reached French Polynesia for the first time in 2013, leading to an epidemic affecting 10% of the total population. So far, it has not been known to induce any neurological complications, but, a few weeks after the outbreak, an unexpectedly high number of 42 patients presented with Guillain-Barré syndrome.We report the clinical and electrophysiological characteristics of this series. Males predominated with a sex ratio of 2.82 (mean age: 46). All patients (except 2) were native Polynesian. At admission, 55% were able to walk unaided against 38% at nadir, 24% had swallowing troubles (nadir: 45%), 74% had motor weakness of the limbs (nadir: 86%) and deep tendon reflexes were diminished or not found in the vast majority of patients. Mean duration of the progressive phase and of the plateau phase was respectively 7 and 9 days. Thirty-eight percent of the patients were admitted in intensive care unit and 10 patients underwent tracheotomy. Nerve electrophysiological studies at admission showed marked distal motor conduction alterations, which had almost completely disappeared at the 4th month; this pattern was more suggestive of acute motor axonal neuropathy (AMAN) than of acute inflammatory demyelinating polyneuropathy (AIDP). Lumbar puncture showed elevated proteins in 90% of the cases, with cell count always inferior to 50/μL.This epidemic raises several questions, such as the potential existence of interactions between Zika virus and Polynesian HLA system and/or the consequences of several recombination events of this virus. This situation should call for increased vigilance, especially in countries where Aedes mosquitoes are present.

To report patient/family experiences and outcomes after tracheostomy International survey of patients and families with tracheostomy. Collaboration of the Patient Safety and Quality Improvement Committee of the American Academy of Otolaryngology-Head and Neck Surgery and the Global Tracheostomy Collaborative. A 50-item survey was developed with multistakeholder collaboration. The survey was disseminated via international social networks used by patients with a tracheostomy and their families. Qualitative and quantitative data were analyzed. Of 220 respondents, 90% cared for a pediatric patient with a tracheostomy. Only 48% of respondents felt "very prepared" at time of discharge, and 11% did not receive emergency preparedness training prior to discharge. Home nursing needs were inadequately met in 17% of families, with resulting difficulties shortly after discharge; 14% sought emergent care within 1 week of discharge. Nearly half of respondents indicated a desire to have met with a patient with a tracheostomy prior to surgery but were not offered that opportunity. Fragmented care or limited teamwork was reported by 32% of respondents, whereas tracheotomy care was described as "integrated" or "maximally integrated" for 67%. While many families report satisfaction with tracheostomy care, opportunities remain for improving care. This study highlights the importance of teaching, teamwork, and smoothing transition from the hospital. Potential quality improvement areas include standardizing tracheostomy teaching for routine and emergency needs and optimizing postdischarge support and coordination. Prior to surgery, connecting families to people with a tracheostomy may also be beneficial. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

To identify clinical factors associated with enteral feeding tube placement in a head and neck cancer population. A self-administered survey was given to patients being treated for head and neck cancer while they were waiting to be seen in 1 of 4 otolaryngology clinics. The post hoc analysis presented here combines survey and chart review data to determine clinical and demographic variables associated with feeding tube placement. Four otolaryngology clinics. Otolaryngology clinic patients being treated for head and neck cancer. Enteral feeding tube placement. Of the 724 patients eligible for this study, 14% (n = 98) required enteral feeding tube placement. Multivariate analysis found the following variables to be independently associated with feeding tube placement: oropharynx/hypopharynx tumor site (odds ratio [OR], 2.4; P = .01), tumor stage III/IV (OR, 2.1; P = .03), flap reconstruction (OR, 2.2; P = .004), current tracheotomy (OR, 8.0; P<.001), chemotherapy (OR, 2.6; P<.001), and increased age (OR, 1.3; P = .02). In addition, there was a curvilinear relationship between time since treatment and feeding tube placement, with about 30% having a feeding tube at 1 month posttreatment, tapering down during the first 3 years to about 8% and leveling off thereafter. Identification of factors associated with an increased risk of feeding tube placement may allow physicians to better counsel patients regarding the possibility of feeding tube placement during treatment. Since feeding tube placement has been linked to decreased quality of life in head and neck cancer, such counseling is an integral part of the clinical management of these patients.

For two years the State of Israel has been treating casualties from the Syrian civil war. The Galilee Medical Center in Nahariya is the main hospital for this humanitarian mission. Objectives: To evaluate the demographic and clinical characteristics of the casualties that were treated in our department. Information from medical records of all Syrian casualties evacuated to the Galilee Medical Center were evaluated. Between March 2013 and December 2014, 450 casualties were evacuated to the Galilee Medical Center. Of those, 45 were treated in the Department of Otolaryngology - Head and Neck Surgery. Of the 45 cases, 43 were male (95.5%) and the mean age was 30.4 years (range 1-79 years). There was a significant difference in terms of gender (p <0.0001). The majority of cases (42.1%) were aged 21-27 years. The most common cause of injury was a gunshot wound. Thirty five patients (77.7%) suffered from multiple trauma, and complex injuries of the maxillofacial bones and upper respiratory tract. Eight (18%) of the cases arrived at the medical center with a tracheotomy. The average length of hospital stay was 15 days (range: 1-141). Of the 450 cases, 97.3% were discharged back to Syria, and 12 died. Of all Syrian injured treated in the ENT department, the vast majority were young men. The main cause of injury was gunshot wounds. It is likely that the lack of protective gear that exist in western armies is a factor in the complex injuries treated at the Galilee Medical Center.

Angioneurotic edema of the upper aerodigestive tract (AEUAT) often challenges the otolaryngologist with the decision of surgical intervention versus observation. To develop a logical approach to the evaluation and management of the airway in patients with AEUAT, emphasizing fiberoptic examination (FOE) findings. A computer-based retrospective review of all patients diagnosed with AEUAT was performed. The charts were reviewed for demographics, etiology, medical history, presentation, physical examination, imaging studies, intervention, and outcome. Findings on FOE as well as other covariants were statistically compared. Seventy patients with AEUAT were identified. The etiologies consisted of 24 cases of angiotensin converting enzyme inhibitor use (33%), 10 allergic reactions (17%), 1 hereditary (1.5%), and 35 idiopathic cases (48%). Fourteen patients underwent airway intervention, including 6 tracheotomies and 8 intubations. Of the 14 patients, 5 underwent emergent intervention before fiberoptic examination, 4 had laryngeal edema only, and 5 had both laryngeal and base of tongue edema. No patients with both laryngeal and base of tongue edema were observed. The remaining 52 patients were observed in a monitored setting and required no subsequent intervention. FOE is an invaluable tool in the assessment of the compromised airway in patients with angioneurotic edema Laryngeal edema alone is an ominous physical finding. When laryngeal and pharyngeal edema are present together, the physician should consider immediate intervention. Our findings indicate that symptoms, including stridor, hoarseness, and dysphagia, do correlate with disease severity; however, they must be confirmed with fiberoptic visualization. Although sound clinical judgment should always be exercised, we present our results in the management of the acute airway in angioneurotic edema.

Persistent lung atelectasis is difficult to treat and perfluorochemical (PFC) liquid may be an option for bronchioalveolar lavage (BAL). A 4-year-old girl with spinal muscle atrophy was admitted in respiratory failure. On admission, the X-ray confirmed the persistence of total right-sided lung atelectasis, which had been present for 14 months. She was endotracheally intubated and ventilated from the day of admission. BAL with normal saline was performed twice without improvement. Following failed extubation and being dependent on continuous respiratory support, a trial of BAL using PFC liquid (Perfluorodecalin HP) was carried out. The PFC was delivered through the endotracheal tube on three consecutive days. A loading dose of 3 ml/kg was administered, followed by a varying dose in order to more effectively lavage the lungs. She tolerated the procedure well the first 2 days, although there were no clinical signs of improvement in the atelectasis. Intentionally, higher inflation pressures were applied after PFC instillation on day 3. Chest X-ray then showed hazy infiltrates on her left lung and she required more ventilatory support. However, lung infiltrates cleared over the next 3 days. A tracheotomy was done 6 days after the last PFC instillation. She had a slow recovery and was successfully decanulated. Clinical improvement of lung function was seen including less need of BiPAP and oxygen. A chest CT scan showed then functional lung tissue appearing in the previous total atelectatic right lung. Lavage with PFC can safely be performed with a therapeutic effect in a child with unilateral total lung atelectasis. Copyright © 2011 Wiley Periodicals, Inc.

Chronically critically ill patients have recurrent infections, organ dysfunction, and at least half die within 1 year. They are frequently cared for in long-term acute care hospitals, yet little is known about their experience in this setting. Our objective was to explore the understanding and expectations and goals of these patients and surrogates. We conducted semi-structured interviews with chronically critically ill long-term acute care hospital patients or surrogates. Conversations were recorded, transcribed, and analyzed. One long-term acute care hospital. Chronically critically ill patients, defined by tracheotomy for prolonged mechanical ventilation, or surrogates. Semi-structured conversation about quality of life, expectations, and planning for setbacks. A total of 50 subjects (30 patients and 20 surrogates) were enrolled. Thematic analyses demonstrated: 1) poor quality of life for patients; 2) surrogate stress and anxiety; 3) optimistic health expectations; 4) poor planning for medical setbacks; and 5) disruptive care transitions. Nearly 80% of patient and their surrogate decision makers identified going home as a goal; 38% were at home at 1 year. Our study describes the experience of chronically critically ill patients and surrogates in an long-term acute care hospital and the feasibility of patient-focused research in this setting. Our findings indicate overly optimistic expectations about return home and unmet palliative care needs, suggesting the need for integration of palliative care within the long-term acute care hospital. Further research is also needed to more fully understand the challenges of this growing population of ICU survivors.

Contributions of Ibn Zuhr (Avenzoar) to the progress of surgery: a study and translations from his book Al-Taisir.

This study of the original Arabic edition of the book Al-Taisir Fil-Mudawat Wal-Tadbeer (Book of Simplification Concerning Therapeutics and Diet) written by the Muslim physician Abu-Marwan Abdel-Malik Ibn Zuhr (Avenzoar, 1093-1162 AD) aimed at evaluating his contributions to the progress of surgery and providing English translations of relevant excerpts. Ibn Zuhr s unique experiment performing a tracheotomy on a goat, proved the safety of this operation in humans and represented a further step in the development of the experimental school started by Al-Razi (Rhazes) of Baghdad in the ninth century who is known to have given monkeys doses of mercury to test it as a drug for human use. Ibn Zuhr also performed post mortems on sheep in the course of his clinical research on treatment of ulcerating diseases of the lungs. Same as all his predecessors in the Islamic Era, he stressed the importance of a practical and sound knowledge of anatomy for surgical trainees. Furthermore, Ibn Zuhr insisted on a well supervised and structured training program for the surgeon-to-be, before allowing him to operate independently. He also drew the red lines at which a physician should stop, during his general management of a surgical condition; a step forward in the evolution of general surgery as a specialty of its own. He believed in prophylaxis against urinary stone disease and reported the importance of dietary management for that purpose. Furthermore, Ibn Zuhr enriched surgical and medical knowledge by describing many diseases and treatment innovations not ever described before him.

Blunt cerebrovascular trauma causing vertebral arteryd issection in combination with a laryngeal fracture: a case report

PubMed Central

2011-01-01

Introduction The diagnosis and therapy of blunt cerebrovascular injuries has become a focus since improved imaging technology allows adequate description of the injury. Although it represents a rare injury the long-term complications can be fatal but mostly prevented by adequate treatment. Case presentation A 33-year-old Caucasian man fell down a 7-meter scarp after losing control of his quad bike in a remote area. Since endotracheal intubation was unsuccessfully attempted due to the severe cervical swelling as well as oral bleeding an emergency tracheotomy was performed on scene. He was hemodynamically unstable despite fluid resuscitation and intravenous therapy with vasopressors and was transported by a helicopter to our trauma center. He had a stable fracture of the arch of the seventh cervical vertebra and fractures of the transverse processes of C5-C7 with involvement of the lateral wall of the transverse foramen. An abort of the left vertebral artery signal at the first thoracic vertebrae with massive hemorrhage as well as a laryngeal fracture was also detected. Further imaging showed retrograde filling of the left vertebral artery at C5 distal of the described abort. After stabilization and reconfirmation of intracranial perfusion during the clinical course weaning was started. At the time of discharge, he was aware and was able to move all extremities. Conclusion We report a rare case of a patient with vertebral artery dissection in combination with a laryngeal fracture after blunt trauma. Thorough diagnostic and frequent reassessments are recommended. Most patients can be managed with conservative treatment. PMID:21843321

Assess the safety and efficacy of combined antegrade and retrograde esophageal dilation (CARD) for complete esophageal stenosis following head and neck cancer (HNC) treatment. Review HNC dysphagia management. Retrospective review of all patients undergoing CARD following HNC treatment between May 2001 and September 2008. Forty-five patients were identified for review. Parameters assessed included: ability to obtain intraoperative esophageal patency, complications, number of dilations required, diet, and gastric tube (GT) status. Factors associated with dilation failure were analyzed. Intraoperative esophageal patency was obtained in 91% of patients. Median number of all dilations per patient was three. Median number of CARDs per patient was one. Resumption of oral intake occurred in 36/45 (80%). Diet results included: regular or soft diet 32/45 (71%), GT removal 27/45 (60%), and GT dependence with nothing by mouth 9/45 (20%). Laryngeal and pharyngeal stenosis, radionecrosis, tracheotomy dependence, and elongated stenosis were associated with dilation failure. Complications occurred in 18/63 (29%) CARD procedures: eight pneumomediastinum, seven GT site problems, two esophageal perforations, and one pharyngeal infection. All complications resolved spontaneously or with minimal interventions. CARD was safe and effective. Intraoperative patency was achieved in 91% of patients. Eighty percent resumed oral intake. The majority of patients had their GTs removed and resumed a soft or regular diet. Dilation failure was associated with laryngeal, pharyngeal, and excessively long esophageal stenosis, often resulting from radionecrosis. Complications were minor. CARD should be considered before relegating patients with complete esophageal stenosis to chronic GT dependence or subjecting them to laryngopharyngo esophagectomy.

According to Professor Basil T. Darras, Professor of Neurology (Pediatrics) at Harvard Medical School and Director of the Spinal Muscular Atrophy (SMA) Program at Boston Children's Hospital in Boston (MA, USA), the diagnosis of SMA type I is clinical and is based on detailed general physical and neurological examinations. SMA type I remains the most common genetic disease resulting in death in infancy and is really devastating for the child, the parents, as well as the medical professionals with the privilege of caring for patients with SMA and their parents. The proposed management options include: i) no respiratory support; ii) non-invasive ventilation; and iii) tracheotomy with mechanical ventilation. Deciding, which option is the best, is indeed a very personal decision. The optimal clinical care should be extremely mindful of parents' wishes and management goals with regard to the quality of life. Since the end of 2016 in the USA, and recently in Europe, there exists the possibility of accessing a novel treatment drug for SMA, namely Nusinersen. This antisense oligonucleotide is administered intrathecally and increases the production of the fully functional SMN protein, thus improving motor function, the quality of life and survival. Among the ongoing clinical trials, oral treatment with RG7916, a small molecule SMN2 splicing modifier, appears to be really promising. Gene therapy using viral vectors is expected to offer an ‘one and done’ therapy and possibly a cure, if administered early in life, before any symptoms appear. It is really interesting that viruses, which at the moment are the cause of death of children with SMA, if genetically modified, may be used for their treatment. PMID:29556256

Chung, Phil-Sang; Lee, Sang Joon

2012-02-01

Objectives: Laser cordectomy is very popular nowadays and become one of the treatments of choice for early glottis carcinoma. Transoral laser microsurgery has many advantages comparing conventional open surgery or radiation therapy. In this study, we examined the oncologic results of laser cordectomy for early glottic cancer and analyzed the prognostic impact on the survival of the several tumor-related and treatment-related factors. Methods: Patients who were diagnosed as early glottic squamous cell carcinoma, treated by laser cordectomy with curative intent were analyzed. Patients with preivous radiation therapy were included. From June 1988 to March 2005, 202 patients from five hospitals were analyzed (174 T1, 28 T2). Results: Five-year overall survival and disease-free survival were 98.4% and 84.9%. Twenty two patients developed local recurrence. Total laryngectomy was done in 6 patients and laryngeal preservation rate was 97%. Recurrence was higher in the patients with anterior commissure involvement (9/39) than without anterior commissure involvement (13/163). Recurrence was higher in T1b (4/15) than T1a (13/159). Previous radiation was also highly related to the recurrence (7/20 vs 15/182). Twenty patients with local recurrence after radiation therapy were treated by salvage laser cordectomy. Of them, 7 patients developed local recurrence and 5 year disease-free survival was 57%. Complication was rare with one case of hemorrhage. Tracheotomy was not necessary in all patients. Conclusions: Laser cordectomy for early glottic carcinoma showed high survival, laryngeal preservation rate and low complication rate. The prognostic factors were anterior commissure involvement, both vocal fold involvement and previous radiotherapy.

Surgery of adult bilateral vocal fold paralysis in adduction: history and trends.

Bilateral vocal fold paralysis (BVFP) in adduction is characterised by inspiratory dyspnea, due to the paramedian position of the vocal folds with narrowing of the airway at the glottic level. The condition is often life threatening and therefore requires surgical intervention to prevent acute asphyxiation or pulmonary consequences of chronic airway obstruction. Aside from corticosteroid administration and intubation, which are only temporary measures, the standard approach for improving respiration is to perform a tracheotomy. Over the past century, a vast majority of surgical interventions have been developed and applied to restore the patency of the airway and achieve decannulation. Surgeons can generally choose for every individual patient from various well-established treatment options, which have a predictable outcome. An overview of the surgical techniques for laryngeal airway enlargement in BVFP is presented. Included are operative techniques, which have found application in clinical practice, and only to a small extent in purely anatomic or animal studies. The focus is on two major groups of interventions--for temporary and for definitive glottic enlargement. The major types of interventions include the following: (1) resection of anatomical structures; (2) retailoring and displacing the existing structures, with minimal tissue removal; (3) displacing existing structures, without tissue resection; (4) restoration or substitution of the missing innervation of the laryngeal musculature. The single interventions of these four major types have always followed the development of the medical equipment and anaesthesia. At the beginning of the twentieth century, when medicine was unable to counteract surgical infection, endoscopic or extramucosal surgical techniques were dominant. In the 1950s, the microscopic endoscopic laryngeal surgery boomed. At the end of the twentieth century many of the classical endoscopic operations were performed either with the help of surgical lasers alone, or in combination with other interventions.

Systemic inflammatory response syndrome is associated with excessive production of nitric oxide (NO·) and superoxide (O2), forming peroxynitrite, which in turn, acts as a terminal mediator of cellular injury by producing cell necrosis and apoptosis. We examined the effect of the peroxynitrite decomposition catalyst, WW-85, in a sheep model of acute lung injury and septic shock. Eighteen sheep were operatively prepared and randomly allocated to the sham, control, or WW-85 group (n = 6 each). After a tracheotomy, acute lung injury was produced in the control and WW-85 groups by insufflation of four sets of 12 breaths of cotton smoke. Then, a 30-mL suspension of live Pseudomonas aeruginosa bacteria (containing 2 - 5 × 10¹¹ colony-forming units) was instilled into the lungs according to an established protocol. The sham group received only the vehicle (30 mL saline). The sheep were studied in awake state for 24 h and ventilated with 100% oxygen. WW-85 was administered 1 h after injury as bolus infusion (0.1 mg/kg), followed by a continuous infusion of 0.02 mg·kg⁻¹·h⁻¹ until the end of the 24-h experimental period. Compared with injured but untreated controls, WW-85-treated animals had significantly improved gas exchange, reductions in airway obstruction, shunt formation, lung myeloperoxidase concentrations, lung malondialdehyde concentrations, lung 3-nitrotyrosine concentrations, and plasma nitrate-to-nitrite levels. Animals treated with WW-85 exhibited less microvascular leakage and improvements in pulmonary function. These results provide evidence that blockade of the nitric oxide-peroxynitrite pathway improves disturbances from septic shock, as demonstrated in a clinically relevant ovine experimental model.

Initial approaches to and treatments of infants with Robin sequence (RS) is diverse and inconsistent. The care of these sometimes critically ill infants involves many different medical specialties, which can make the decision process complex and difficult. To optimize the care of infants with RS, we present our institution's approach and a review of the current literature. A retrospective cohort study was conducted among 75 infants diagnosed with RS and managed at our institution in the 1996-2012 period. Additionally, the conducted treatment regimen in this paper was discussed with recent literature describing the approach of infants with RS. Forty-four infants (59%) were found to have been treated conservatively. A significant larger proportion of nonisolated RS infants than isolated RS infants needed surgical intervention (53 vs. 25%, p = .014). A mandibular distraction was conducted in 24% (n = 18) of cases, a tracheotomy in 9% (n = 7), and a tongue-lip adhesion in 8% (n = 6). Seventy-seven percent of all infants had received temporary nasogastric tube feeding. The literature review of 31 studies showed that initial examinations and the indications to perform a surgical intervention varied and were often not clearly described. RS is a heterogenic group with a wide spectrum of associated anomalies. As a result, the decisional process is challenging, and a multidisciplinary approach to treatment is desirable. Current treatment options in literature vary, and a more uniform approach is recommended. We provide a comprehensive and pragmatic approach to the analysis and treatment of infants with RS, which could serve as useful guidance in other clinics.

Hypertensive cerebral hemorrhage (HCH) is a potentially life-threatening cerebrovascular disease with high mortality. In case of a massive hematoma, surgical drainage is a crucial treatment. The aim of the present study was to assess the efficacy of the endoscope-assisted keyhole technique in elderly patients with intracerebral hematoma who needed a flap craniotomy as traditional treatment. One hundred-eighty-four elderly patients with HCH, who had craniotomy indications after conservative treatment for 6-24 hours after onset, were randomly divided into two groups. In the craniotomy group, traditional hematoma drainage was performed. In the keyhole group, an endoscope-assisted keyhole technique was used. Anesthesia time, blood loss, hematoma drainage rate, and complications were compared. The clinical primary outcome was the six-month efficacy rate (defined by the activities of daily living (ADL) score). Anesthesia time was longer in the craniotomy group (3.43 ± 0.65 vs. 1.53 ± 0.52 h, P < 0.01), and blood losses were more important (256 ± 129 vs. 96 ± 39 ml P < 0.01). There was no difference in hematoma drainage rate between the two groups (77.25 ± 13.44 vs. 83.52 ± 27.51% P > 0.05). Complications, including tracheotomy (P < 0.01), pulmonary infection (P < 0.01) and hypoproteinemia (P < 0.05) were more frequent in the craniotomy group. There was no difference in the occurrence of other complications, including revision surgery digestive tract ulcer and epilepsy. Proportion of patients with good prognosis (ADL I-III) was larger in the keyhole group (P < 0.05). In elderly HCH patients with an indication for hematoma drainage, better outcomes were achieved using an endoscope-assisted keyhole technique.

Despite poor outcomes, life-sustaining treatments including mechanical ventilation are continued for a large and growing population of patients with chronic critical illness. This may be owing in part to a lack of understanding resulting from inadequate communication between clinicians and patients and families. Our objective was to investigate the informational needs of patients with chronic critical illness and their families and the extent to which these needs are met. In this prospective observational study conducted at 5 adult intensive care units in a large, university-affiliated hospital in New York, New York, 100 patients with chronic critical illness (within 3-7 days of elective tracheotomy for prolonged mechanical ventilation) or surrogates for incapacitated patients were surveyed using an 18-item questionnaire addressing communication about chronic critical illness. Main outcome measures included ratings of importance and reports of whether information was received about questionnaire items. Among 125 consecutive, eligible patients, 100 (80%) were enrolled; questionnaire respondents included 2 patients and 98 surrogates. For all items, more than 78% of respondents rated the information as important for decision making (>98% for 16 of 18 items). Respondents reported receiving no information for a mean (SD) of 9.0 (3.3) of 18 items, with 95% of respondents reporting not receiving information for approximately one-quarter of the items. Of the subjects rating the item as important, 77 of 96 (80%) and 69 of 74 (93%) reported receiving no information about expected functional status at hospital discharge and prognosis for 1-year survival, respectively. Many patients and their families may lack important information for decision making about continuation of treatment in the chronic phase of critical illness. Strategies for effective communication in this clinical context should be investigated and implemented.

To describe and compare characteristics, ventilatory practices, and associated outcomes among mechanically ventilated patients with different types of brain injury and between neurologic and nonneurologic patients. Secondary analysis of a prospective, observational, and multicenter study on mechanical ventilation. Three hundred forty-nine intensive care units from 23 countries. We included 552 mechanically ventilated neurologic patients (362 patients with stroke and 190 patients with brain trauma). For comparison we used a control group of 4,030 mixed patients who were ventilated for nonneurologic reasons. None. We collected demographics, ventilatory settings, organ failures, and complications arising during ventilation and outcomes. Multivariate logistic regression analysis was performed with intensive care unit mortality as the dependent variable. At admission, a Glasgow Coma Scale score ≤8 was observed in 68% of the stroke, 77% of the brain trauma, and 29% of the nonneurologic patients. Modes of ventilation and use of a lung-protective strategy within the first week of mechanical ventilation were similar between groups. In comparison with nonneurologic patients, patients with neurologic disease developed fewer complications over the course of mechanical ventilation with the exception of a higher rate of ventilator-associated pneumonia in the brain trauma cohort. Neurologic patients showed higher rates of tracheotomy and longer duration of mechanical ventilation. Mortality in the intensive care unit was significantly (p < .001) higher in patients with stroke (45%) than in brain trauma (29%) and nonneurologic disease (30%). Factors associated with mortality were: stroke (in comparison to brain trauma), Glasgow Coma Scale score on day 1, and severity at admission in the intensive care unit. In our study, one of every five mechanically ventilated patients received this therapy as a result of a neurologic disease. This cohort of patients showed a higher mortality rate than nonneurologic patients despite a lower incidence of extracerebral organ dysfunction.

Abstract Zika virus (transmitted by mosquitoes) reached French Polynesia for the first time in 2013, leading to an epidemic affecting 10% of the total population. So far, it has not been known to induce any neurological complications, but, a few weeks after the outbreak, an unexpectedly high number of 42 patients presented with Guillain–Barré syndrome. We report the clinical and electrophysiological characteristics of this series. Males predominated with a sex ratio of 2.82 (mean age: 46). All patients (except 2) were native Polynesian. At admission, 55% were able to walk unaided against 38% at nadir, 24% had swallowing troubles (nadir: 45%), 74% had motor weakness of the limbs (nadir: 86%) and deep tendon reflexes were diminished or not found in the vast majority of patients. Mean duration of the progressive phase and of the plateau phase was respectively 7 and 9 days. Thirty-eight percent of the patients were admitted in intensive care unit and 10 patients underwent tracheotomy. Nerve electrophysiological studies at admission showed marked distal motor conduction alterations, which had almost completely disappeared at the 4th month; this pattern was more suggestive of acute motor axonal neuropathy (AMAN) than of acute inflammatory demyelinating polyneuropathy (AIDP). Lumbar puncture showed elevated proteins in 90% of the cases, with cell count always inferior to 50/μL. This epidemic raises several questions, such as the potential existence of interactions between Zika virus and Polynesian HLA system and/or the consequences of several recombination events of this virus. This situation should call for increased vigilance, especially in countries where Aedes mosquitoes are present. PMID:27057874

The number of obese patients is increasing and more obese patients are likely to present for surgical repair of aortic dissection Type A (ADA). We evaluated the effect of this procedure on mortality and morbidity of patients based on their body-mass-index (BMI; kg*m -2 ). A total of 667 patients that underwent surgical repair of ADA between 2003 and 2017 were retrospectively analyzed. Patients were divided into four groups according to BMI: normal weight (18≤BMI<25; n=186), overweight (25≤BMI<30; n=238), obese (30≤BMI<35, n=144), and morbidly obese (BMI≥35; n=99). We compared clinical features and outcomes. There was no statistical difference regarding clinical presentation or proximal or distal aortic repair. Postoperative complications were similar among all groups. While the rate for reintubation, tracheotomy, and the length of stay in the intensive care unit tended to be similar, the time to extubation and the total length of hospital stay were significantly longer in morbidly obese patients. Significantly more blood was transfused and replaced in the normal weight patients compared to the obese patients: in median 69% of the calculated blood volume was replaced in the normal weight patients compared to 32% in the morbidly obese patients (p<0.001). In-hospital mortality and late survival were similar among all weight groups. Despite the comorbidities that are associated with obesity, obese patients undergoing surgical repair of ADA are not at greater risk of death or other adverse outcomes. An immediate surgical approach should be considered in all patients independent of weight. Copyright © 2018. Published by Elsevier Inc.

Place of death in patients with amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a degenerative neurological disorder that affects motor neurons. Involvement of respiratory muscles causes the failure of the ventilator pump with more or less significant bulbar troubles. ALS course is highly variable but, in most cases, this disease entails a very significant burden for patients and caregivers, especially in the end-of-life period. In order to analyze the characteristics of ALS patients who die at home (DH) and in hospital (DHosp) and to study the variability of clinical practice, a retrospective medical records analysis was performed (n=77 from five hospitals). time elapsed since the onset of symptoms and the beginning of ventilation, characteristics of ventilation (device, mask and hours/day), and support devices and procedures. In all, 14% of patients were ventilated by tracheotomy. From the analysis, 57% of patients were of DH. Mean time since the onset of symptoms was 35.93±25.89 months, significantly shorter in patients who DHosp (29.28±19.69 months) than DH (41.12±29.04) (p=0.044). The percentage of patients with facial ventilation is higher in DHosp (11.4% vs 39.4%, p<0.005). DH or not is related to a set of elements in which health resources, physician attitudes and support resources in the community play a role in the decision-making process. There is great variability between countries and between hospitals in the same country. Given the variability of circumstances in each territory, the place of death in ALS might not be the most important element; more important are the conditions under which the process unfolds.

2003-03-01

To present selected highlights from the evolution of diagnosis of laryngeal disease and treatment of laryngeal cancer from ancient Greece until the 20th century. Historical study of diagnosis of laryngeal disease and treatment of laryngeal cancer from the ancient Greek medical scriptures until the most recent evolutional steps in the 20th century. Original Greek-language texts of ancient and Byzantine medical writers were studied and literature on history of medicine was investigated to reveal early knowledge of diagnostic and therapeutic techniques for laryngeal disease and cancer of the larynx. Diseases of the upper aerodigestive tract were known and treated by ancient Greek physicians, and, later, Byzantine doctors, apart from preserving ancient medical concepts, contributed their own ideas, mainly about surgery and postoperative care. The initial therapeutic approach for the disorders caused by laryngeal tumors was either tracheotomy or endotracheal intubation in an attempt to prevent suffocation. In more recent times, construction of the laryngoscope and other modern examination instruments, as well as the final acceptance of histological diagnosis based on tissue biopsy, has allowed for accurate diagnosis and successful treatment of laryngeal lesions. Preoperational biopsy, application of pharyngoesophageal speech and advanced vocal devices for the laryngectomees, and invention of antibiotic and anesthetic agents had led, by the middle of the 20th century, to the establishment of extended and radical surgical techniques as optional treatment for laryngeal cancer. In addition, the discovery of x-rays and radium introduced radiotherapy as an alternative in the treatment procedure for cancer of the larynx. Progress in the evolution of laryngological diagnosis and practice demanded efforts by many daring and courageous investigators and surgeons, contributing new ideas and techniques in the development of modern laryngology.

ICU admission is required in more than 25% of patients with chronic obstructive pulmonary disease (COPD) at some time during the course of the disease. However, only limited information is available on how physicians communicate with COPD patients about ICU admission. COPD patients and relatives from 19 French ICUs were interviewed at ICU discharge about their knowledge of COPD. French pulmonologists self-reported their practices for informing and discussing intensive care treatment preferences with COPD patients. Finally, pulmonologists and ICU physicians reported barriers and facilitators for transfer of COPD patients to the ICU and to propose invasive mechanical ventilation. Self-report questionnaires were filled in by 126 COPD patients and 102 relatives, and 173 pulmonologists and 135 ICU physicians were interviewed. For 41% (n = 39) of patients and 54% (n = 51) of relatives, ICU admission had never been expected prior to admission. One half of patients were not routinely informed by their pulmonologist about possible ICU admission at some time during the course of COPD. Moreover, treatment options (that is, non-invasive ventilation, intubation and mechanical ventilation or tracheotomy) were not explained to COPD patients during regular pulmonologist visits. Pulmonologists and ICU physician have different perceptions of the decision-making process pertaining to ICU admission and intubation. The information provided by pulmonologists to patients and families concerning the prognosis of COPD, the risks of ICU admission and specific care could be improved in order to deliver ICU care in accordance with the patient's personal values and preferences. Given the discrepancies in the decision-making process between pulmonologists and intensivists, a more collaborative approach should probably be discussed.

In order to study cardiac excitability and the effects of procaine, ventricular tachycardia was induced by intramyocardial injection of 0.05 ml 50% aconite solution in irradiated and nonirradiated rabbits of both sexes. Tracheotomy and thoracotomy were performed to facilitate access to the heart and to establish artificial respiration through a tracheal tube. Narcosis was induced by urethane. Electrocardiograms were made at various stages in both control and irradiated animals; the former showed no change in preliminary phases of the experiment. Procaine was administered by subcutaneous injection, bilateral vagosympathetic infiltration, or slow intravenous infusion. Its therapeutic effect was determined by givingmore » it 5 min after trachycardia occurred, and its preventive action by giving it 5 min before. The x irradiation rate was 16.6 r/min, to a total dose of 1000 r. On the 3rd day after irradiation, the therapeutic effect of procaine after intramuscular injection was seen as a 50% normalization of heart action, with less by other routes of administration; its preventive effect was seen as a 58% normalization following slow intravenous infusion but was insignificant by other routes. Six days after irradiation, at the peak of radiation sickness, procaine's therapeutic and preventive actions had almost disappeared; its intravenous therapeutic application gave 25% normalization and its intramuscular preventive action provided 20% normalization of heart rate. However, on the 6th day, a profibrillatory effect was observed, especially in the therapeutic vagosympathetic infiltration technique and the preventive use by slow intravenous infusion. Suggested explanations of the reversal are: change in excitability of myocardium when it is irradiated, or change in effect of procaine when the whole organism is irradiated. Results favor the first explanation. (BBB)« less

To evaluate whether the presence of pseudobulbar affect (PBA) in an early stage of the disease influences survival in a population-based incident cohort of amyotrophic lateral sclerosis (ALS). Incident ALS cases, diagnosed according to El Escorial criteria, were enrolled from a prospective population-based registry in Puglia, Southern Italy. The Center for Neurologic Study-Lability Scale (CNS-LS), a self-administered questionnaire, was used to evaluate PBA. Total scores range from 7 to 35. A score ≥13 was used to identify PBA. Cox proportional hazard models were used for survival analysis. The modified C-statistic for censored survival data was used for models' discrimination. RECursive Partitioning and AMalgamation (RECPAM) analysis was used to identify subgroups of patients with different patterns of risk, depending on baseline characteristics. We enrolled 94 sporadic ALS, median age of 64 years (range: 26-80). At the censoring date, 65 of 94 (69.2%), 39 of 60 (65.0%), and 26 of 34 (76.5%) patients reached the outcome (tracheotomy/death), in the whole, non-PBA and in the PBA groups, respectively. Kaplan-Meier survival curves for the two subgroups were not significantly different (log-rank test: 1.3, P = .25). The discrimination ability of a multivariable model with demographic and clinical variables of interest was not improved by adding PBA.

Sulfur mustard (SM) is a strong vesicant agent which has been used in several military conflicts. Large stockpiles still exist to the present day. SM is believed to be a major threat to civilian populations because of the persistent asymmetric threat by non-state actors, such as terrorist groups, its easy synthesis and handling and the risk of theft from stockpiles. Following an asymptomatic interval of several hours, acute SM exposure produces subepidermal skin blisters, respiratory tract damage, eye lesions and bone marrow depression. Iranian victims of SM exposure during the Iran-Iraq (1984-1988) war were treated at intensive care units of 3 Munich hospitals. All 12 patients were injured following aerial attacks with SM filled bombs, which exploded in a distance between 5 and 30m. All patients soon noted an offensive smell of garlic, addle eggs or oil roasted vegetables. No individual protective equipment was used. Eye itching and skin blistering started 2h after SM exposure. Some patients complained of nausea, dizziness and hoarseness. 4h after exposure, most patients started vomiting. Eye symptoms worsened and most patients suffered from temporary blindness due to blepharospasm and lid oedema. Additionally, pulmonary symptoms such as productive cough occurred. Patients were transferred to Munich 4-17 days after SM exposure. On admission all patients showed significant skin blistering and pigmentation. Conjunctivitis and photophobia were the major eye symptoms. Pulmonary symptoms, including productive cough were persistent. Bronchoscopy revealed massive inflammation of the trachea with signs of necrosis. 3 patients needed tracheotomy. Chest X-ray did not yield abnormal observations. This presentation summarizes the experience of treating SM victims in Munich and discusses therapeutic implications.

Spinal muscular atrophy type I and the dual role of viruses: An interview with Professor Basil T. Darras, Professor of Neurology (Pediatrics) at Harvard Medical School.

According to Professor Basil T. Darras, Professor of Neurology (Pediatrics) at Harvard Medical School and Director of the Spinal Muscular Atrophy (SMA) Program at Boston Children's Hospital in Boston (MA, USA), the diagnosis of SMA type I is clinical and is based on detailed general physical and neurological examinations. SMA type I remains the most common genetic disease resulting in death in infancy and is really devastating for the child, the parents, as well as the medical professionals with the privilege of caring for patients with SMA and their parents. The proposed management options include: i) no respiratory support; ii) non-invasive ventilation; and iii) tracheotomy with mechanical ventilation. Deciding, which option is the best, is indeed a very personal decision. The optimal clinical care should be extremely mindful of parents' wishes and management goals with regard to the quality of life. Since the end of 2016 in the USA, and recently in Europe, there exists the possibility of accessing a novel treatment drug for SMA, namely Nusinersen. This antisense oligonucleotide is administered intrathecally and increases the production of the fully functional SMN protein, thus improving motor function, the quality of life and survival. Among the ongoing clinical trials, oral treatment with RG7916, a small molecule SMN2 splicing modifier, appears to be really promising. Gene therapy using viral vectors is expected to offer an 'one and done' therapy and possibly a cure, if administered early in life, before any symptoms appear. It is really interesting that viruses, which at the moment are the cause of death of children with SMA, if genetically modified, may be used for their treatment.

Endoscopic laterofixation in bilateral vocal cords paralysis in children.

2010-06-01

Vocal cords paralysis is the second most frequent cause of laryngeal stridor in children. Symptoms of congenital vocal cords paralysis can occur shortly after birth or later. Vocal cords paralysis can be unilateral or bilateral. Symptoms of unilateral paralysis include hoarse weeping or stridor during a deep inhalation. In children unilateral vocal cords paralysis often retreats spontaneously or can be completely compensated. Children with bilateral vocal cords paralysis present mainly breathing disorders while phonation is normal. Symptoms are different, starting from complete occlusion of respiratory tracts and ending on small symptoms connected with the lack of effort tolerance. When symptoms are severe, patients from this group require a tracheotomy. The lack of restoration of normal function of vocal cords or lack of complete compensation and maintenance of symptoms are an indication for surgical treatment. The aim of this study is to present results of the treatment of bilateral vocal cords paralysis in children using the endoscopic method of laterofixation of vocal cords. In the Pediatric ENT Department between 1998 and 2009 sixty four children with dyspnoea and/or phonation disorders caused by vocal cords paralysis were treated. In ten cases laterofixation of vocal cords was performed, in most cases with good result. In this article the authors present the method of endoscopic laterofixation and achieved results. Endoscopic laterofixation of vocal cords in children is a safe and an easy method of surgical treatment of bilateral vocal cords paralysis. This method can be used as a first and often as a one stage treatment of vocal cords paralysis. In some cases this procedure is insufficient and has to be completed with other methods.

The objective of the present study was to determine the antihyperalgesic effect of sertraline, measured indirectly by the changes of sciatic afferent nerve activity, and its effects on cardiorespiratory parameters, using the model of formalin-induced inflammatory nociception in anesthetized rats. Serum serotonin (5-HT) levels were measured in order to test their correlation with the analgesic effect. Male Wistar rats (250-300 g) were divided into 4 groups (N = 8 per group): sertraline-treated group (Sert + Saline (Sal) and Sert + Formalin (Form); 3 mg·kg−1·day−1, ip, for 7 days) and saline-treated group (Sal + Sal and Sal + Form). The rats were injected with 5% (50 µL) formalin or saline into the right hind paw. Sciatic nerve activity was recorded using a silver electrode connected to a NeuroLog apparatus, and cardiopulmonary parameters (mean arterial pressure, heart rate and respiratory frequency), assessed after arterial cannulation and tracheotomy, were monitored using a Data Acquisition System. Blood samples were collected from the animals and serum 5-HT levels were determined by ELISA. Formalin injection induced the following changes: sciatic afferent nerve activity (+50.8 ± 14.7%), mean arterial pressure (+1.4 ± 3 mmHg), heart rate (+13 ± 6.8 bpm), respiratory frequency (+4.6 ± 5 cpm) and serum 5-HT increased to 1162 ± 124.6 ng/mL. Treatment with sertraline significantly reduced all these parameters (respectively: +19.8 ± 6.9%, -3.3 ± 2 mmHg, -13.1 ± 10.8 bpm, -9.8 ± 5.7 cpm) and serum 5-HT level dropped to 634 ± 69 ng/mL (P < 0.05). These results suggest that sertraline plays an analgesic role in formalin-induced nociception probably through a serotonergic mechanism. PMID:22086464

Adult patients who required mechanical ventilation (MV) for longer than 24 hours. None. Demographic data, APACHE II, SOFA, reason for MV, comorbidity, functional condition, reintubation, duration of MV, tracheotomy, ICU mortality, in-hospital mortality. A total of 1661 patients were recruited. Males accounted for 67.9% (n=1127), with a mean age of 62.1 ± 16.2 years. APACHE II: 20.3 ± 7.5. Total SOFA: 8.4 ± 3.5. Four hundred and twenty-three patients (25.4%) were ≥ 75 years of age. Comorbidity and functional condition rates were poorer in these patients (p<0.001 for both variables). Mortality in the ICU was higher in the elderly patients (33.6%) than in the younger subjects (25.9%) (p=0.002). Also, in-hospital mortality was higher in those ≥ 75 years of age. No differences in duration of MV, prevalence of tracheostomy or reintubation incidence were found. Regarding the indication for MV, only the patient ≥ 75 years of age with pneumonia, sepsis or trauma had a higher in-ICU mortality than the younger patients (46.3% vs 33.1%, p=0.006; 55% vs 25.8%, p=0.002; 63.6% vs 4.5%, p<0,001, respectively). No differences were found referred to other reasons for MV. Older patients (≥ 75 years) have significantly higher in-ICU and in-hospital mortality than younger patients without differences in the duration of mechanical ventilation. Differences in mortality were at the expense of pneumonia, sepsis and trauma. Copyright © 2012 Elsevier España, S.L. and SEMICYUC. All rights reserved.

Background: Recently, mutations in the transient receptor potential cation channel, subfamily V, member 4 gene (TRPV4) have been reported in Charcot-Marie-Tooth Type 2C (CMT2C) with vocal cord paresis. Other mutations in this same gene have been described in separate families with various skeletal dysplasias. Further clarification is needed of the different phenotypes associated with this gene. Methods: We performed clinical evaluation, electrophysiology, and genetic analysis of the TRPV4 gene in 2 families with CMT2C. Results: Two multigenerational families had a motor greater than sensory axonal neuropathy associated with variable vocal cord paresis. The vocal cord paresis varied from absent to severe, requiring permanent tracheotomy in 2 subjects. One family with mild neuropathy also manifested pronounced short stature, more than 2 SD below the average height for white Americans. There was one instance of dolichocephaly. A novel S542Y mutation in the TRPV4 gene was identified in this family. The other family had a more severe, progressive, motor neuropathy with sensory loss, but less remarkable short stature and an R315W mutation in TRPV4. Third cranial nerve involvement and sleep apnea occurred in one subject in each family. Conclusion: CMT2C with axonal neuropathy, vocal cord paresis, and short stature is a unique syndrome associated with mutations in the TRPV4 gene. Mutations in TRPV4 can cause abnormalities in bone, peripheral nerve, or both and may result in highly variable orthopedic and neurologic phenotypes. GLOSSARY CMAP = compound muscle action potential; CMT = Charcot-Marie-Tooth; CMT2C = Charcot-Marie-Tooth Type 2C; HMSN = hereditary motor and sensory neuropathy; NCV = nerve conduction velocity; RFLP = restriction fragment length polymorphism; SMA = spinal muscular atrophy; SNAP = sensory nerve action potential; SPSMA = scapuloperoneal spinal muscular atrophy.

There is little evidence in the medical literature to guide empiric treatment of pediatric patients with long-term tracheostomies who present with signs and symptoms of a bacterial respiratory infection. The overall goal of this study was to describe the respiratory microbiology in this study population at our institution. This study was a retrospective chart review of all subjects with tracheostomies currently receiving care at the Arkansas Center for Respiratory Technology Dependent Children. Descriptive statistics were used to describe the respiratory microbiology of the full study group. Several subgroup analyses were conducted, including description of microbiology according to time with tracheostomy, mean time to isolation of specific organisms after the tracheostomy tube was placed, association between Pseudomonas aeruginosa or methicillin-resistant Staphylococcus aureus isolation and prescribed antibiotic courses, and description of microbiology according to level of chronic respiratory support. Available respiratory culture results up to July 2011 were collected for all eligible subjects. Descriptive statistics were used to describe subject characteristics, and chi-square analysis was used to analyze associations between categorical data. P < .05 was considered statistically significant. A total of 93 subjects met inclusion criteria for the study. The median (interquartile range) age at time of tracheotomy was 0.84 (0.36-3.25) y, and the median (interquartile range) time with tracheostomy was 4.29 (2.77-9.49) y. The most common organism isolated was P. aeruginosa (90.3%), with Gram-negative organisms predominating. However, 55.9% of the study population had a respiratory culture positive for methicillin-resistant S. aureus. The first organism isolated after tracheostomy placement was Methiciliin-sensitive S. aureus was isolated the soonest after tracheostomy placement. Specific organisms were not related to level of chronic respiratory support or likelihood of receiving antibiotics. This study provides an updated overview of the variety of potential pathogens isolated from respiratory cultures of pediatric subjects with long-term tracheostomies.

Cancer patients after neck surgeries require specific operative and postoperative management, which to some extent determines the final outcome of the surgery. Such procedures require particular attention due to the respiratory and gastrointestinal tracts as well as the presence of functionally and morphologically important anatomical structures on the neck. The majority of patients qualified for surgery have concomitant medical conditions, which increases the probability of certain operative and postoperative complications. Preparation for the procedure requires close cooperation between the laryngologist-head and neck surgeon, general practitioner and anaesthetist. The purpose of the paper was to analyse the factors that influence the normal process of healing in the operative and postoperative periods in patients after neck surgery. The study group consisted of 220 patients who underwent neck surgery in the years 2007-2010. 92.8% of the operations were performed due to a malignant cancer. The following factors were taken into consideration in the evaluation of the healing process: On average, following surgery, patients stayed in the ward for: 5-7 days after selective removal of lymph nodes, 5 days after removal of branchial cleft cyst or persistent thyroglossal duct, 14 days after total laryngectomy, and 12 days after reconstructive laryngeal surgery. All patients after oncological surgery of the oral cavity, oropharynx and larynx stayed in the ICU for the first 24 hours and remained under analgosedation. Laryngeal surgery was performed using a separate surgical incision for tracheotomy. In all cases suction drainage was used for 48 hours. After surgery, patients were mobilised during the first 24 hours in the ward. Appropriate operative and postoperative management, following specific standards, increases the safety of the patient. Providing optimal conditions for healing shortens the patient's stay in the ICU, which reduces the cost of hospitalisation and increases the patient's comfort and quality of life.

Abstract To identify risk factors for post-thyroidectomy hematoma requiring airway intervention or surgery (“wound hematoma”) and determine post-thyroidectomy time to intervention. Post-thyroidectomy hematoma is rare but potentially lethal. Information on wound hematoma in a nationwide clinical setting is scarce. Using the Japanese Diagnosis Procedure Combination database, we extracted data from records of patients undergoing thyroidectomy from July 2010 to March 2014. Patients with clinical stage IV cancer or those with bilateral neck dissection were excluded because they could have undergone planned tracheotomy on the day of thyroidectomy. We assessed the association between background characteristics and wound hematoma ≤2 days post-thyroidectomy, using multivariable logistic regression analysis. Among 51,968 patients from 880 hospitals, wound hematoma occurred in 920 (1.8%) ≤2 days post-thyroidectomy and in 203 (0.4%) ≥3 days post-thyroidectomy (in-hospital mortality = 0.05%). Factors significantly associated with wound hematoma ≤2 days post-thyroidectomy were male sex (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.30–1.77); higher age (OR 1.01, 95% CI 1.00–1.02); overweight or obese (OR 1.22, 95% CI 1.04–1.44); type of surgery (partial thyroidectomy for benign tumor compared with: total thyroidectomy, benign tumor [OR 1.95, 95% CI 1.45–2.63]; partial thyroidectomy, malignant tumor [OR 1.21, 95% CI 1.00–1.46]; total thyroidectomy, malignant tumor [OR 2.49, 95% CI 1.82–3.49]; and thyroidectomy for Graves disease [OR 3.88, 95% CI 2.59–5.82]); neck dissection (OR, 1.53, 95% CI 1.05–2.23); antithrombotic agents (OR 1.58, 95% CI 1.15–2.17); and blood transfusion (OR 5.33, 95% CI 2.39–11.91). Closer monitoring of airway and neck is recommended for patients with risk factors, and further cautious monitoring beyond 3 days post-thyroidectomy. PMID:26886632

Acid aspiration is a serious complication that can occur during general anesthesia. Studies show that beta-agonists have beneficial effects on lung injury. Therefore, we tested the effect of the nebulized beta-agonist fenoterol on lung variables in a rodent model of acid-induced lung injury. In a prospective, randomized, and controlled study, we evaluated the effects of fenoterol inhalation on lung oxygenation, inflammation, and pulmonary histology in a rat model of acid-induced lung injury. Sprague-Dawley rats underwent sevoflurane anesthesia with tracheotomy and carotid catheter insertion. Lung injury was induced by instillation of 0.4 mL/kg 0.1 M hydrochloric acid. The lungs were ventilated for 6 h and randomized to receive either fenoterol inhalation 10 microg or saline inhalation, both at 15 and 180 min after acid aspiration. Mean arterial blood pressures and peak airway pressures were documented, arterial blood gases were determined at 30, 90, 180, 270, and 360 min, and postmortem histology was subsequently examined. Additionally, fenoterol concentrations in bronchoalveolar lavage fluid (BALF) and plasma were determined by liquid chromatography/tandem mass spectroscopy. After 360 min tumor necrosis factor (TNF)-alpha and interleukin (IL)-6 were determined in the BALF, and lungs were dried for determination of the wet/dry ratio. Inhalation treatment with 10 microg fenoterol significantly increased oxygenation after 270 and 360 min when compared with placebo. Fenoterol-treated rats showed a significant decrease in IL-6 and TNF-alpha levels and in the wet/dry weight ratio of the lungs. The histologic appearance showed significantly less interstitial edema and leukocyte infiltration in the fenoterol group. The concentration of fenoterol was 10.3 microg/L (median) in the BALF and <1 microg/L in the plasma. Fenoterol inhalation improved oxygenation after 270 and 360 min, attenuated the release of TNF-alpha and IL-6, and diminished the lung edema and infiltration of polymorphonuclear leukocytes.

Thyroid cancer is the most common endocrine malignancy with an incidence equal to 1% of all malignant tumors. Prognostic factors affecting survival are manifold, including in several classifications (AMES, AGES, CORN and TNM). In this sense, the invasion of adjacent structures is one of the most important variables. The authors describe the experience of a single center in surgical treatment of advanced thyroid cancer. Between 1986 and 2010 , 1565 patients were undergoing surgery with thyroid cancer. In particular, 1403 interventions were made for differentiated cancer, 97 for medullary carcinoma, 25 for insular carcinoma, 29 for anaplastic carcinoma, 2 for plasmacytoma, and 7 for lymphoma and 2 for angiosarcoma. Among these 896 showed invasion of adjacent structures and / or distant metastases. There were no perioperative deaths or major complications. Surgical procedures consisted of: 13 loboistmectomy, 519 total thyroidectomy (TT), 325 TT with lymphadenectomy of the central compartment, 7 TT with radical lymphectomy, 621 TT with functional lymphectomy, 6 TT with breast lumpectomy, 5 TT with with video-assisted lung metastasectomy, 16-TT with resection and tracheal anastomosis, 6 TT with laryngotracheal resection, 3 TT with laryngectomy, 4 TT with trachetomy, 28 TT with respiratory stent placement, 12 tracheotomy. At present, 1328 patients were free of disease, while 104 showed recurrence. Total of 133 deaths were recorded, all linked to disease relapse. The role of surgery in the treatment of advanced thyroid cancer is still undeniable. In the presence of extracapsular trespassing, in fact, the adoption of interventions demolition permits long-term survival, given the lack of aggressiveness of the tumor differentiated representing the majority of cases. The aim of surgical radicalization addition, even in the presence of distant metastases, it is justified by the possibilities offered by the therapeutic radioiodine treatment, which is not feasible in the presence of significant amounts of thyroid tissue which picks. In the presence of undifferentiated tumors, finally, endoscopic or surgical treatment may be indicated by simple purpose of palliation of respiratory symptoms.

Background Post-intubation tracheoesophageal fistula (PITEF) is an often mistreated, severe condition. This case series reviewed for both the choice and timing of surgical technique and outcome PITEF patients. Methods This case series reviewed ten consecutive patients who had undergone esophageal defect repair and airway resection/reconstruction between 2000 and 2014. All cases were examined for patients: general condition, medical history, preparation to surgery, diagnostic work-up, timing of surgery and procedure, fistula size and site, ventilation type, nutrition, post-operative course and complications. Results All patients were treated according to Grillo’s technique. Overall, 6/10 patients had undergone a preliminary period of medical preparation. Additionally, 3 patients had already had a tracheostomy, one had had a gastrostomy and 4 had both. One patient had a Dumon stent with enlargement of the fistula. Concomitant tracheal stenosis had been found in 7 patients. The mean length of the fistulas was 20.5 mm (median 17.5 mm; range, 8–45 mm), at a median distance from the glottis of 43 mm (range, 20–68 mm). Tracheal resection was performed in all ten cases. The fistula was included in the resection in 6 patients, while it was excluded in the remaining 4 due to their distance. Post-repair tracheotomy was performed in 3 patients. The procedure was performed in 2 ventilated patients. Morbidity related to fistula and anastomosis was recorded in 3 patients (30%), with one postoperative death (10%); T-Tube placement was necessary in 3 patients, with 2/3 decannulations after long-stenting. Definitive PITEF closure was obtained for all patients. At 5-year follow-up, the 9 surviving patients had no fistula-related morbidity. Conclusions Primary esophageal closure with tracheal resection/reconstruction seemed to be effective treatment both short and long-term. Systemic conditions, mechanical ventilation, detailed preoperative assessment and appropriate preparation were associated with outcome. Indeed, the 3 patients who had received T-Tube recovered from anastomotic complications. PMID:28275475

Objectives: In Switzerland, assisted suicide (AS) is legal, provided that the person seeking assistance has decisional capacity and the person assisting is not motivated by reasons of self-interest. However, in this particular setting nothing is known about patients’ and their caregivers’ attitudes toward AS and life-prolonging measures. Methods: Data was retrieved through validated questionnaires and personal interviews in 33 patients and their caregivers covering the following domains: physical function according to the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R), demographic data, quality of life, anxiety, depression, social situation, spirituality, burden of disease, life-prolonging, and life-shortening acts. Results: In patients the median time after diagnosis was 9 months (2–90) and the median Amyotrophic Lateral Sclerosis (ALS) FRS-R score was 37 (22–48). The majority of patients (94%; n = 31) had no desire to hasten death. Patients’ and caregivers’ attitudes toward Percutaneous Endoscopic Gastrostomy (PEG) and Non-Invasive Ventilation (NIV) differed. Significantly more patients than caregivers (21.2 versus 3.1%) stated that they were against NIV (p = 0.049) and against PEG (27.3 versus 3.1%; p = 0.031). Answers regarding tracheotomy were not significantly different (p = 0.139). Caregivers scored significantly higher levels of “suffering” (p = 0.007), “loneliness” (p = 0.006), and “emotional distress” answering the questionnaires (p < 0.001). Suffering (p < 0.026) and loneliness (p < 0.016) were related to the score of the Hospital Anxiety and Depression Scale (HADS) in patients. Conclusion: A liberal legal setting does not necessarily promote the wish for AS. However, the desire to discuss AS is prevalent in ALS patients. There is a higher level of suffering and loneliness on the caregivers’ side. A longitudinal study is warranted. PMID:23112784

To evaluate the effectiveness of the submental island pedicled flap (SIPF) for the repair of oral soft defects following oral cancer ablation. Thirty consecutive patients undergoing resection of oral cancer followed by reconstruction with SIPF from February 2010 to March 2013 were reviewed. The effectiveness complications, oral function recovering and oncologic outcomes after reconstructive operation with SIPF were evaluated.SPSS software was used to analyze the data. The dimensions of SIPF ranged from a minimum of 4 cm×6 cm to a maximum of 6 cm×15 cm. Of the 30 flaps, 28 were survival completely, one had superficial necrosis but healed with treatments, and one failed due to complete necrosis, with a survival rate of 96.7% (29/30). Operative time ranged from a minimum of 4.5 hours to a maximum of 7.5 hours, mean 6.8 hours, and hospital stay time was 11-18 days, mean 13 days. Thirteen patients (43.3%) received tracheotomy before SIPF operation. Surgical or postoperative complications included temporary marginal mandibular never palsy in one case, neck hematoma in one case, hydrops in the mandibular region in 7 cases, and neck infectionin in 2 cases. Postoperative functional results showed mouth opening was normal in 23 patients, light limitation of mouth opening in 6 cases and obvious limitation of mouth opening in one case. The speech function was re-obtained satisfactorily in 29 patients, but one case with poor speech function. Most patients showed normal swallowing function, of them 26 patients on a full oral diet, 3 patients on a soft diet and one patient on a liquid diet only. Postoperative follow-up time was for 6-19 months (median 13 months), and 4 patients had local recurrence and 2 patients had cervical lymph node metastases. The SIPF is safe, reliable and simple for the reconstruction of middle-small oral soft defects following resection of early-stage oral cancer.

Does Bilevel Positive Airway Pressure Improve Outcome of Acute Respiratory Failure after Open-heart Surgery?

Elgebaly, Ahmed Said

2017-01-01

Background: Respiratory failure is of concern in the postoperative period after cardiac surgeries. Invasive ventilation (intermittent positive pressure ventilation [IPPV]) carries the risks and complications of intubation and mechanical ventilation (MV). Aims: Noninvasive positive pressure ventilation (NIPPV) is an alternative method and as effective as IPPV in treating insufficiency of respiration with less complications and minimal effects on respiratory and hemodynamic parameters next to open-heart surgery. Design: This is a prospective, randomized and controlled study. Materials and Methods: Forty-four patients scheduled for cardiac surgery were divided into two equal groups: Group I (IPPV) and Group II (NIPPV). Heart rate (HR), mean arterial pressure (MAP), respiratory rate (RR), oxygen saturation (SpO2), arterial blood gas, weaning time, reintubation, tracheotomy rate, MV time, postoperative hospital stay, and ventilator-associated pneumonia during the period of hospital stay were recorded. Results: There was statistically significant difference in HR between groups with higher in Group I at 30 and 60 min and at 12 and 24 h. According to MAP, it started to increase significantly at hypoxemia, 15 min, 30 min, 4 h, 12 h, and at 24 h which was higher in Group I also. RR, PaO2, and PaCO2 showed significant higher in Group II at 15, 30, and 60 min and 4 h. According to pH, there was a significant difference between groups at 15, 30, and 60 min and at 4, 12, and 24 h postoperatively. SpO2 showed higher significant values in Group I at 15 and 30 min and at 12 h postoperatively. Duration of postoperative supportive ventilation was higher in Group I than that of Group II with statistically significant difference. Complications were statistically insignificant between Group I and Group II. Conclusion: Our study showed superiority of invasive over noninvasive mode of ventilator support. However, NIPPV (bilevel positive airway pressure) was proved to be a safe method. PMID:28994676

The evaluation of advertising, products, and packaging is traditionally performed through methods based on self-reports and focus groups, but these approaches often appear poorly accurate in scientific terms. Neuroscience is increasingly applied to the investigation of the neurophysiological bases of the perception of and reaction to commercial stimuli to support traditional marketing methods. In this context, a particular sector or marketing is represented by public service announcements (PSAs). The objective of this protocol is to apply electroencephalography (EEG) and autonomic signal analysis to study responses to selected antismoking PSAs. Two EEG indices were employed: the frontal alpha band EEG asymmetry (the Approach Withdrawal (AW) index) and the frontal theta (effort index). Furthermore, the autonomic Emotional Index (EI) was calculated, as derived from the Galvanic Skin Response (GSR) and Heart Rate (HR) signals. The present protocol describes a series of operational and computational steps required to properly estimate, through the aforementioned indices, the emotional and cerebral reaction of a group of subjects towards a selected number of antismoking PSAs. In particular, a campaign characterized by a symbolic communication style (classified as "awarded" on the basis of the prizes received by specialized committees) obtained the highest approach values, as estimated by the AW index. A spot and an image belonging to the same PSA campaign based on the "fear arousing appeal" and with a narrative/experiential communication style (classified as "effective" on the basis of the economical/health-related improvements promoted) reported the lowest and highest effort values, respectively. This is probably due to the complexity of the storytelling (spot) and to the immediateness of the image (a lady who underwent a tracheotomy). Finally, the same "effective" campaign showed the highest EI values, possibly because of the empathy induced by the testimonial and the explicitness of the message. PMID:28872117

Obstructive sleep apnea (OSA) increases susceptibility to atrial fibrillation (AF) by a combined sympatho-vagal hyperactivation. The purpose of this study was to investigate the effect of autonomic nervous system modulation by low-level baroreceptor stimulation (LL-BRS) compared to high-level BRS (HL-BRS) on atrial arrhythmogenic changes in a pig model of OSA. Sixteen pigs received tracheotomy under general urethane/chloralose anesthesia. Group 1 pigs (n = 8) received LL-BRS (at 80% of that slowing sinus rate) for 3 hours and group 2 pigs (n = 8) received HL-BRS (slowing sinus rate). Changes in atrial effective refractory period (AERP) and AF-inducibility were determined during applied negative thoracic pressure (NTP) for 2 minutes before and at the end of the 3-hour stimulation protocol. Group 1: LL-BRS prolonged AERP from 150 ± 5 to 172 ± 19 milliseconds (P < 0.001). After 3 hours of LL-BRS, NTP-induced AERP-shortening was diminished from -51 ± 10 milliseconds (-34%) to -22 ± 4 milliseconds (-13%) (P < 0.01). AF-inducibility during NTP maneuvers decreased from 90% at baseline to 15% (P < 0.01). Group 2: HL-BRS shortened AERP from 150 ± 17 to 132 ± 8 milliseconds (P = 0.024). After 3 hours of HL-BRS, NTP-induced AERP-shortening was increased from -55 ± 7 milliseconds (-36%) to -72 ± 11 milliseconds (-54%) (P < 0.05) and AF-inducibility was not affected. NTP-induced changes in blood gases and blood pressure were not different between the groups. LL-BRS suppressed NTP-induced AERP-shortening and AF-inducibility. By contrast HL-BRS further perpetuated NTP-induced AERP-shortening and increased AF-inducibility. These findings support only the use of LL-BRS as a novel therapeutic modality to treat AF in OSA. © 2016 Wiley Periodicals, Inc.

A Life-Threatening Mediastinal Hematoma After Central Venous Port System Implantation

Patient: Female, 68 Final Diagnosis: Mediastinal hematoma Symptoms: Agitation • severe hemodynamic instability • severe respiratory distress Medication: — Clinical Procedure: Cardiopulmonary resuscitation • reintubation • thoracic drain Specialty: Surgery Objective: Diagnostic/therapeutic accidents Background: We report a case of surgical central venous port system implantation using Seldinger’s technique with a life-threatening mediastinal hematoma due to the perforation of the superior vena cava. Case Report: A 68-year-old woman was admitted to our institution for port implantation. Open access to the cephalic vein and 2 punctures of the right subclavian vein were unsuccessful. Finally, the port catheter could be placed into the superior vena cava using Seldinger’s technique. As blood aspiration via the port catheter was not possible, fluoroscopy was performed, revealing mediastinal contrast extravasation without contrasting the venous system. A new port system could be placed in the correct position without difficulties. After extubation, the patient presented with severe respiratory distress and required consecutive cardiopulmonary resuscitation and reintubation. The CT scan showed a significant hematoma in the lower neck and posterior mediastinum with tracheal compression. We assumed a perforation of the superior vena cava with the tip of the guidewire using Seldinger’s technique. Long-term intensive treatment with prolonged ventilation and tracheotomy was necessary. The port system had to be subsequently explanted due to infection. Conclusions: Mediastinal hematoma is a rare but life-threatening complication associated with central venous catheterization using Seldinger’s technique. Perforation occurs most often during central venous catheterization in critical care. Mediastinal hematoma is an example of a mechanical complication occurring after central venous catheterization, which has been described only a few times in the literature to date. This case highlights the importance of awareness of possible, rare, life-threatening complications during port implantation, mostly performed in multimorbid patients by surgeons in training.

Predictive factors for pharyngocutaneous fistulization after total laryngectomy: a Dutch Head and Neck Society audit.

Incidences of pharyngocutaneous fistulization (PCF) after total laryngectomy (TL) reported in the literature vary widely, ranging from 2.6 to 65.5%. Comparison between different centers might identify risk factors, but also might enable improvements in quality of care. To enable this on a national level, an audit in the 8 principle Dutch Head and Neck Centers (DHNC) was initiated. A retrospective chart review of all 324 patients undergoing laryngectomy in a 2-year (2012 and 2013) period was performed. Overall PCF%, PCF% per center and factors predictive for PCF were identified. Furthermore, a prognostic model predicting the PCF% per center was developed. To provide additional data, a survey among the head and neck surgeons of the participating centers was carried out. Overall PCF% was 25.9. The multivariable prediction model revealed that previous treatment with (chemo)radiotherapy in combination with a long interval between primary treatment and TL, previous tracheotomy, near total pharyngectomy, neck dissection, and BMI < 18 were the best predictors for PCF. Early oral intake did not influence PCF rate. PCF% varied quite widely between centers, but for a large extend this could be explained with the prediction model. PCF performance rate (difference between the PCF% and the predicted PCF%) per DHNC, though, shows that not all differences are explained by factors established in the prediction model. However, these factors explain enough of the differences that, compensating for these factors, hospital is no longer independently predictive for PCF. This nationwide audit has provided valid comparative PCF data confirming the known risk factors from the literature which are important for counseling on PCF risks. Data show that variations in PCF% in the DHNCs (in part) are explainable by the variations in these predictive factors. Since elective neck dissection is a major risk factor for PCF, it only should be performed on well funded indication.

We describe the relationship between donor-recipient lung-size mismatch and postoperative mechanical ventilation tidal volumes according to recipient- and donor-predicted body weights in a cohort of bilateral lung transplant patients. A most-undersized (10 patients with lowest predicted total lung capacity [pTLC] ratio = pTLC-donor/pTLC-recipient), a most-oversized (10 patients with highest pTLC ratio) and best-matched subset (10 patients with predicted total lung capacity ratio closest to 1.0) were selected within a cohort of 70 patients. All tidal volumes during mechanical ventilation in the first 96 h after bilateral lung transplantation were recorded. Tidal volumes were expressed in ml and ml/kg-recipient-predicted body weights and ml/kg-donor-predicted body weights. Postoperative absolute tidal volumes (in ml) were comparable between subsets of patients with undersized, matched and oversized allografts (552 ± 103 vs 581 ± 107 vs 582 ± 104 ml), and tidal volumes in ml/kg-recipient-predicted body weights were also similar (8.8 ± 1.4 vs 9.3 ± 1.1 vs 9.8 ± 2.1). However, tidal volumes in ml/kg-donor-predicted body weights revealed significant differences between undersized, matched, and oversized subsets (11.4 ± 3.1 vs 9.4 ± 1.2 vs 8.1 ± 2.1, respectively; P < 0.05). Two patients developed primary graft dysfunction grade 3, both in the undersized subset. Four patients in the undersized group underwent tracheotomy (vs none in matched and one in oversized subset). During mechanical ventilation after bilateral lung transplantation, undersized allografts received relatively higher tidal volumes compared with oversized allografts when the tidal volumes were related to donor-predicted body weights.

To evaluate the effects of two different kinds of airway humidification for tracheostomy patients, and to provide their relevant clinical effect and suggestions for their use. Online databases, including PubMed, EMBASE, JBI evidence-based nursing center library, the Cochrane Library, and Chinese databases (CNKI, Wanfang database, VIP, CBM) were searched systematically up to March 2015. Randomized controlled trials (RCTs) were considered eligible for inclusion if the following criteria were met: no history of respiratory tract infection; satisfactory nutritional status; tracheotomy performed; 18 years older. Two different humidification methods were used. Continuous airway humidification was used in the experiment group, while intermittent airway humidification was used in the control group. Two qualified reviewers reviewed the original articles, evaluating the quality of articles, and data were extracted independently. The enrolled RCTs were analyzed by Meta-analysis. A total of nine RCTs were included, containing 631 cases, among them 316 cases in expertment group, and 315 cases in control group. Continuous airway humidification was shown to be able to reduce the incidence of irritable cough [odds ratio (OR) = 0.20, 95% confidence interval (95%CI) = 0.12-0.34, P < 0.000?01], bleeding form mucosa of respiratory tract (OR = 0.25, 95%CI = 0.14-0.45, P < 0.000?01), sputum conglomeration (OR = 0.19, 95%CI = 0.10-0.39, P < 0.000?01), and pneumonia (OR = 0.29, 95%CI = 0.19-0.45, P < 0.000?01). The funnel plots were largely symmetrical, suggesting there was no publication bias in the Meta-analysis of two methods for airway humidification for tracheostomy patients. Because the number of including articles was relative small, and the quality of some articles was poor, it is impossible to draw a reliable conclusion that continuous airway humidification could lower the incidence of complications for patients undergone tracheostomy.

Objective: To summarize the short- and mid-term results on endovascular repair of primary retrograde Stanford type A aortic dissection with an entry tear in distal aortic arch or descending aorta. Methods: Between December 2009 and December 2014, 21 male patients of primary retrograde Stanford type A aortic dissection with a mean age of (52±9) years received endovascular repair in Department of Cardiothoracic Surgery, Jinling Hospital. Among the 21 cases, 17 patients were presented as ascending aortic intramural hematoma, 4 patients as active blood flow in false lumen and partial thrombosis, 8 patients as ulcer on descending aorta combined intramural hematoma in descending aorta, and 13 patients as typical dissection changes. All patients received endovascular stent-graft repair successfully, with 15 cases in acute phase and 6 cases in chronic phase. Results: Cone stent was implanted in 13 cases, while straight stent in 8 cases, including 1 case of left common carotid-left subclavian artery bypass surgery and 1 case of restrictive bare-metal stent implantation. No perioperative stroke, paraplegia, stent fracture or displacement, limbs or abdominal organ ischemia or other severe complications occured, except for tracheotomy in 2 patients. Active blood flow in ascending aorta or aortic arch disappeared, and intramural hematoma started being absorbed on CT angiography images before discharge. All patients were alive during follow-up (6 to 72 months), and intramural hematoma in ascending aorta and aortic arch was absorbed thoroughly. Type Ⅰ endoleak and ulcer expansion were found in 1 patient, and type Ⅳ endoleak in distal stent was found in another one patient. Secondary ascending aortic dissection was found in 1 case two years later, which was cured by hybrid procedure with cardiopulmonary bypass. Conclusion: Endovascular repair of primary retrograde Stanford type A aortic dissection was safe and effective, which correlated with favorable short- and mid-term results.

The chronically critically ill have survived acute critical illness but require prolonged mechanical ventilation. These patients are frequently transferred from acute care to long-term acute care hospitals (LTACHs) for prolonged recovery, yet many suffer setbacks requiring readmission to acute care. The patient's relatively improved condition while at the LTACH might be an opportunity for communication regarding care goals; however, there have been no prior studies of the feasibility of such conversations in the LTACH. To determine the feasibility, acceptability, and potential usefulness of conversations about serious illness with chronic critical illness patients or their surrogate decision makers after LTACH admission. We adapted an existing conversation guide for use in chronically critically ill (defined by tracheotomy for prolonged ventilation) LTACH patients or their surrogates to explore views about quality of life, understanding of medical conditions, expectations, and planning for setbacks. These conversations were conducted by one interviewer and summarized for the patients' clinicians. We surveyed patients, surrogates, and clinicians to assess acceptability. A total of 70 subjects were approached and 50 (71%) were enrolled, including 30 patients and 20 surrogates. The median duration of the conversation was 14 minutes 45 seconds [IQR 12:46, 19]. The presence of ongoing mechanical ventilation did not lead to longer conversations; in fact, conversations with patients were shorter than those with surrogates. The majority of subjects (81%) described the conversation as worthwhile. The majority of clinicians (73%) reported that the conversation offered a new and significant understanding of the patient's preferences if a setback were to occur. Conversations about serious illness care goals can be accomplished in a relatively short period of time, are acceptable to chronically critically ill patients and their surrogate decision makers in the LTACH, and are perceived as worthwhile by patients, surrogates, and clinicians.

The epidemiology of chronic critical illness is not well characterized. We sought to determine the prevalence, outcomes, and associated costs of chronic critical illness in the United States. Population-based cohort study using data from the United States Healthcare Costs and Utilization Project from 2004 to 2009. Acute care hospitals in Massachusetts, North Carolina, Nebraska, New York, and Washington. Adult and pediatric patients meeting a consensus-derived definition for chronic critical illness, which included one of six eligible clinical conditions (prolonged acute mechanical ventilation, tracheotomy, stroke, traumatic brain injury, sepsis, or severe wounds) plus at least 8 days in an ICU. None. Out of 3,235,741 admissions to an ICU during the study period, 246,151 (7.6%) met the consensus definition for chronic critical illness. The most common eligibility conditions were prolonged acute mechanical ventilation (72.0% of eligible admissions) and sepsis (63.7% of eligible admissions). Among patients meeting chronic critical illness criteria through sepsis, the infections were community acquired in 48.5% and hospital acquired in 51.5%. In-hospital mortality was 30.9% with little change over the study period. The overall population-based prevalence was 34.4 per 100,000. The prevalence varied substantially with age, peaking at 82.1 per 100,000 individuals 75-79 years old but then declining coincident with a rise in mortality before day 8 in otherwise eligible patients. Extrapolating to the entire United States, for 2009, we estimated a total of 380,001 cases; 107,880 in-hospital deaths and $26 billion in hospital-related costs. Using a consensus-based definition, the prevalence, hospital mortality, and costs of chronic critical illness are substantial. Chronic critical illness is particularly common in the elderly although in very old patients the prevalence declines, in part because of an increase in early mortality among potentially eligible patients.

The evaluation of advertising, products, and packaging is traditionally performed through methods based on self-reports and focus groups, but these approaches often appear poorly accurate in scientific terms. Neuroscience is increasingly applied to the investigation of the neurophysiological bases of the perception of and reaction to commercial stimuli to support traditional marketing methods. In this context, a particular sector or marketing is represented by public service announcements (PSAs). The objective of this protocol is to apply electroencephalography (EEG) and autonomic signal analysis to study responses to selected antismoking PSAs. Two EEG indices were employed: the frontal alpha band EEG asymmetry (the Approach Withdrawal (AW) index) and the frontal theta (effort index). Furthermore, the autonomic Emotional Index (EI) was calculated, as derived from the Galvanic Skin Response (GSR) and Heart Rate (HR) signals. The present protocol describes a series of operational and computational steps required to properly estimate, through the aforementioned indices, the emotional and cerebral reaction of a group of subjects towards a selected number of antismoking PSAs. In particular, a campaign characterized by a symbolic communication style (classified as "awarded" on the basis of the prizes received by specialized committees) obtained the highest approach values, as estimated by the AW index. A spot and an image belonging to the same PSA campaign based on the "fear arousing appeal" and with a narrative/experiential communication style (classified as "effective" on the basis of the economical/health-related improvements promoted) reported the lowest and highest effort values, respectively. This is probably due to the complexity of the storytelling (spot) and to the immediateness of the image (a lady who underwent a tracheotomy). Finally, the same "effective" campaign showed the highest EI values, possibly because of the empathy induced by the testimonial and the explicitness of the message.

2018-01-01

Primary tracheal-bronchial adenoid cystic carcinoma (thoracic adenoid cystic carcinoma; TACC) is a rare and aggressive malignant tumour. Radiotherapy results have not been previously individualised in this setting. Records of 31 patients with TACC (74% tracheal and 26% bronchial) who received radiotherapy between February 1984 and September 2014 were retrospectively analysed. Surgical removal of the primary tumour was carried out for most (71%) patients, and 13/22 (59%) had R1 or R2 (1/22) margins. The mean tumour size was 4.1 cm, 10 (32%) had associated lymph node involvement and 13 (41%) had perineural invasion (PNI). Adjuvant and definitive radiotherapy were delivered for 22 (71%) and nine patients, respectively. The mean delivered dose was 62 Gy (40-70 Gy) and eight patients had a radiotherapy boost (mean 19 Gy, range 9-30 Gy, two with endobronchial brachytherapy). At a median follow-up of 5.7 years, the 5 year overall survival and progression-free survival (PFS) rates were 88% and 61%, respectively. There were three local relapses and 10 metastatic relapses (mean delay 3.2 years), resulting in 5 year local and metastatic relapse rates of 10% and 26%, respectively. The prognostic factors in the univariate analysis for both decreased overall survival and PFS were: age ≥50 years (hazard ratio 6.2 and 3.8) and the presence of PNI (hazard ratio 10.3 and 4.1); and for PFS only: a radiotherapy dose ≤ 60 Gy (hazard ratio 3.1). Late toxicities were: tracheotomy due to symptomatic tracheal stenosis (n = 5), G3 dyspnoea (n = 4), hypothyroidism (n = 5) and pericarditis (n = 4). Radiotherapy dose may affect local control and the presence of PNI should be considered as an adverse prognostic factor. TACC irradiation conferred good local control rates, when comparing these results with historical series. Copyright © 2017 The Royal College of Radiologists. Published by Elsevier Ltd.

In the present study, the voice and functional outcomes of radiofrequency ablation (RFA) and CO2 laser for early glottic cancer were evaluated. One hundred sixty eight patients with early glottic cancer from October 2007 to June 2015 were included. Ninety-seven patients underwent RFA and seventy-one patients underwent CO2 laser. The operation time and score of visual analog scale (VAS) for pain on the second day after surgery were recorded. The electronic laryngoscopy was performed at one week, one month and three months of postoperation. The operation time in RFA was shorter than that in CO2 laser (8.52±1.43min vs. 11.76±1.67min, P<0.05). There was no statistical difference in VAS scores between two operation methods (2.86±0.52 vs. 2.89±0.68, P>0.05). One month after operation, the mucosal recovery in RFA group was better than that in CO2 laser group (P<0.05). The alterations of acoustic parameters Jitter, Shimmer and HNR at three time points after operation showed statistical significances in both RFA and CO2 laser groups (P<0.05). The significant differences in acoustic parameters between two groups were also observed (P<0.05). There were no differences in three-year survival rate, local recurrence rate, recurrence rate with anterior commissure involvement and postoperative adhesion rate with anterior commissure between the patients with RFA and CO2 laser (P>0.05). No patient underwent tracheotomy and had symptoms of bucking, dyspnea, severe pain, hemoptysis and other serious complications. Both RFA and CO2 laser are safe and effective for the treatment of early glottic cancer. RFA has the advantage of quick voice recovery, low mucosa injury and short operation time, which is worthy for wide clinical application. Copyright © 2016 Elsevier Inc. All rights reserved.

Several studies suggest that anesthetics modulate the immune response. The aim of this study was to investigate the effect of halothane and thiopental on the lung inflammatory response. Rats submitted or not to intratracheal (IT) instillation of lipopolysaccharides (LPS) were anesthetized with either halothane (0. 5, 1, or 1.5%) or thiopental (60 mg. kg(-1)) and mechanically ventilated for 4 h. Control rats were treated or not by LPS without anesthesia. Lung inflammation was assessed by total and differential cell counts in bronchoalveolar lavage fluids (BALF) and by cytokine measurements (tumor necrosis factor-alpha [TNF-alpha], interleukin-6 [IL-6], macrophage inflammatory protein-2 [MIP-2], and monocyte chemoattractant protein-1 [MCP-1]) in BALF and lung homogenates. In the absence of LPS treatment, neither halothane nor thiopental modified the moderate inflammatory response induced by tracheotomy or mechanical ventilation. Cell recruitment and cytokine concentrations were increased in all groups receiving IT LPS. However, in halothane-anesthetized rats (halothane > or = 1%), but not in thiopental-anesthetized rats, the LPS-induced lung inflammation was altered in a dose-dependent manner. Indeed, when using 1% halothane, polymorphonuclear leukocyte (PMN) recruitment was decreased by 55% (p < 0.001) and TNF-alpha, IL-6, and MIP-2 concentrations in BALF and lung homogenates were decreased by more than 60% (p < 0.001) whereas total protein and MCP-1 concentrations remained unchanged. The decrease of MIP-2 (observed at the protein and messenger RNA [mRNA] level) was strongly correlated to the decrease of PMN recruitment (r = 0.73, p < 0.05). This halothane-reduced lung inflammatory response was transient and was reversed 20 h after the end of the anesthesia. Our study shows that halothane > or = 1%, delivered during 4 h by mechanical ventilation, but not mechanical ventilation per se, alters the early LPS-induced lung inflammation in the rat, suggesting a specific effect of halothane on this response.

Tracheal stenosis is a debilitating disorder with heterogeneity in terms of disease characteristics and management. Repeated recurrences substantially alter patients' quality of life. There is limited evidence for the use of spray cryotherapy (SCT) in the management of benign airway disease. To report our early results for the use of SCT in patients with benign tracheal stenosis. Data were extracted from the medical records of a consecutive series of patients with benign airway stenosis secondary to granulomatosis with polyangiitis (GPA) (n = 13), prior tracheotomy or tracheal intubation (n = 8), and idiopathic strictures (n = 5) treated from September 1, 2013, to September 30, 2015, at a tertiary care hospital. Airway narrowing was quantified on a standard quartile grading scale. Response to treatment was assessed by improvement in airway caliber and the time interval for reintervention. Delivery of 4 5-second SCT cycles and 2 balloon dilatations. Twenty-six patients (median [range] age, 53 [16-83] years; 20 [77%] female) underwent 48 SCT sessions. Spray cryotherapy was successfully used without any substantial intraoperative or postoperative complications in all patients. In a median (range) follow-up of 11 (1-26) months, all patients had improvement in symptoms. Before the institution of SCT, 23 patients (88%) had grade III or IV stenosis. At the last evaluation after induction of SCT, 4 (15%) had grade III or IV stenosis, with a mean (SD) change of 1.39 (0.51) (P < .001). Patients with GPA required significantly fewer SCT procedures (mean [SD], 1.38 [0.96] vs 2.31 [1.18]; P = .03) during the study period. Spray cryotherapy was a safe adjunct modality to accomplish airway patency in patients with benign tracheal stenosis. Although efficacy evidence is limited for SCT, it may be useful for patients who have experienced treatment failure with conventional modalities. Further analysis of this cohort will determine the physiologic durability of the reported short-term changes. Additional trials are warranted for further evaluation of this modality.

Social networking sites such as Facebook are popular avenues of social discourse among adolescents and young adults, allowing for communication through photographs, videos, and chat features. These websites are also emerging as portals for health-centered support groups, bringing together people with common medical conditions. Adolescents with tracheostomies represent a special and vulnerable patient population. Our aim was to determine whether this particular group of patients found Facebook to be a suitable environment in which to network with other users with tracheostomies. We used our institution's tracheostomy database to obtain a list of all patients between ages of 11-18. We identified 33 patients in this category, and completed a chart review to determine their medical diagnoses as well as age at trach placement. We determined that of these 33 patients, 24 had severe neurocognitive delays that would render them unable to participate in the study. We contacted the remaining nine subjects and obtained appropriate consent for their participation in the study. Of the nine subjects with tracheostomies who completed our survey, four were actively involved with the Facebook community. Two of the four subjects regularly connected with people that they had not met in person, and all four subjects shared the fact that they had a tracheostomy with the Facebook community. Three of the four subjects posted pictures of themselves with their trach sites visible. Finally, three of the four subjects stated that they met and communicated with other Facebook members with tracheostomies. Social networking sites such as Facebook appear to offer an appropriate avenue for adolescents with tracheostomies to network with other users with tracheostomies. Further studies are warranted to assess the reach and social impact of these networking sites as portals of health-centered support groups, however, social networking sites and the cyberspace community may be a promising source of support for adolescents with tracheotomies.

Objectives/Hypothesis To describe the presentation, stenosis characteristics, etiological differences, and outcomes of adult laryngotracheal stenosis treated with endoscopic cold incision, balloon dilation, topical mitomycin C application, and steroid injection. Study Design Retrospective chart review. Methods Demographic and clinical data were extracted for patients treated between March 2000 and December 2010. Prolonged intubation and idiopathic patient data were utilized for comparative analysis. Results Eighty patients (65 females; 15 males; 220 procedures; 2.9 years mean follow-up) presented with dyspnea (81%) and/or exercise intolerance (40%). Most commonly, etiologies were idiopathic (53 of 80; 66%) or prolonged intubation (14 of 80; 18%). Mean procedures per patient and interval between procedures were 2.8 procedures and 405 days, respectively. Mean stenosis length and distance from the caudal phonating edge of the true vocal folds were 9 mm and 19 mm. Complication, tracheotomy, and open-procedure rates were 1.8%, 1.4%, and 10.0%, respectively. Patients with more than two procedures demonstrated a mean 4-mm reduction in stenosis length and a 2-mm cephalad progression of stenosis over time. More caudal stenoses required more frequent procedures. Procedures were less frequent as more procedures were performed. Stenosis characteristics, interval between procedures, and total procedures were similar between idiopathic patients with or without intubation histories, but different between idiopathic and prolonged intubation patients. Conclusions This procedure was shown to be a viable option in adult laryngotracheal stenosis. Repeat dilation was likely, but was performed without adversely affecting stenosis characteristics. Stenoses farther from the vocal folds required procedures more frequently. Idiopathic patients with a history of brief, elective intubation had stenosis characteristics and responses to therapy similar to idiopathic patients without an intubation history. Both idiopathic groups together demonstrated stenosis characteristics and responses to therapy dissimilar to patients with a history of prolonged intubation. PMID:23086662

ALS usually affects highly active, working, sportive individuals. The disease has a devastating impact on the patient's personal life and family ties. Indeed, the disease requires constant attention from the carer for its rapidly progressive nature leads the patient to a complete state of isolation without affecting his/her intellect. For the patient days, are numbered, for the carer, time is limited. The carer must cope with a number of medical, administrative and financial difficulties. These include belated diagnosis with its disastrous consequences on medication, lack of response from the decision-making services, home-improvements or car-fitting. All this requires amazing tenacity from the carer. All the more so as the progress of handicap is relentless and the patient is bound to use different forms of support, walking-stick, zimmer, wheel-chair, hoist, speech synthesis, gastrostomy, tracheotomy or palliative care, which turn out to be more or less effective. But mechanical devices are not enough. Assistance by a nurse, a physiotherapist, a speech therapist and/or a nursing auxiliary is necessary. There are not enough of these assistants and the result cannot be guaranteed, but their role is essential in home care. The carer's investment can be terribly consuming. The burden of 24h care wears out the carer whose days and nights are being regulated by the disease. Not to mention lonely patients with no means of support who find themselves confronted with inevitable daunting problems Institutions providing either temporary or permanent care for ALS patients are scarce. As the condition worsens steadily, the patient suffers sheer desperation and guilt feelings and resents being a burden for family yet would rather stay with them. ARS volunteers who collaborate with medical teams can provide much help. The carer's burden should be greatly lightened too by the newly-installed tutorial system: patients' files will be followed up by one single person after the center's social worker has drawn them up. Medical and home volunteers cooperate to give the patient the feeling that far from being abandoned or ostracized by society, he/she is constantly being given care.

Pediatric head and neck teratomas account for less than 4% of congenital teratomas. The distinct presentations and outcomes of mature and immature head and neck teratomas have not been well established. To review the management and outcomes of pediatric head and neck teratomas. To distinguish differences between mature and immature tumors with respect to the age at presentation and surgery, tumor size and location, alpha fetoprotein (AFP) levels, airway management, and recurrence. A 15-year retrospective chart review of patients treated for head and neck teratomas at Texas Children's Hospital was performed. A total of 20 patients were included. Wilcoxon rank and Fisher's exact tests were used for statistical analysis. Immature teratomas were associated with both higher AFP levels (80800 ng/ml, p = 0.02) and maximum tumor dimensions (14.4 cm, p = 0.0034) than mature teratomas (24400 ng/ml and 6.44 cm). Patients with immature tumors were younger at the time of surgical resection (19.8 days, p = 0.025) compared to those with mature tumors (348 days). 89% of immature teratomas involved anterior neck localization compared to 27% for mature teratomas (p = 0.0098); 88% of the immature teratomas required an EXIT (Ex Utero Intrapartum Treatment) procedure compared with 40% of the mature teratomas (p = 0.0656). Recurrence was noted in only two cases: an immature teratoma 51 months after incomplete resection and a mature teratoma 33 months after complete resection. Long-term consequences of surgical resection included cleft palate (38.9%), dysphagia (33.3%), facial nerve paresis/paralysis (16.7%) and tracheotomy (16.7%). Immature teratomas had higher AFP levels, tumor dimensions, frequency of anterior neck localization, and requirement of EXIT than mature teratomas. Given that there was no significant difference between the recurrence rates of immature and mature teratomas, follow-up vigilance should be maintained equally regardless of tumor maturity.

Anesthesia management in pediatric patients with laryngeal papillomatosis undergoing suspension laryngoscopic surgery and a review of the literature.

PubMed

Bo, Lin; Wang, Bing; Shu, Shi-Yu

2011-11-01

The excision of laryngeal papillomas poses a great challenge for both the anesthesiologist and the surgeon. The narrowness of the airways and the great variability of the pathological lesions necessitate close collaboration between the surgical and anesthesia teams to provide optimal operating conditions and ensure adequate ventilation and oxygenation. Our aim was to explore perioperative anesthesia management in pediatric patients during the excision of laryngeal papillomas with a suspension laryngoscope. Fifty-eight pediatric patients suffering from laryngeal papillomas were included in this retrospective study. These patients had degrees of laryngeal obstruction from I to III and underwent suspension laryngoscopic surgery to excise laryngeal papillomas between January 2007 and December 2010. The American Society of Anesthesiologists (ASA) physical status of the patients ranged from I to III. Anesthesia was induced by intravenous administration. Once the child was unconscious, a 2% lidocaine aerosol solution was sprayed over the laryngeal area directly under the laryngoscope. For patients to tolerate suspension laryngoscopy, it is necessary to maintain spontaneous breathing and ensure adequate anesthesia depth. The airway was secured, and sufficient ventilation was established throughout a tracheal tube (ID 2.5 or 3.0) which was placed close to glottis and connected to Jackson Rees system. Hemodynamic parameters and pulse oxygen saturation (SpO(2)) were closely monitored, and adverse events were recorded. Most of the patients 89% (52/58) were hemodynamically stable during the perioperative period. Laryngospasm and laryngeal edema occurred in several children during emergence from the anesthesia. Tracheal intubations were performed in six patients (10.3%). Tracheotomies were performed in two patients. One patient had to be sent to the ICU for comprehensive therapy. The most important consideration for anesthesia during suspension laryngoscopy is (1) the maintenance of adequate ventilation, (2) to permit surgical exposure, and (3) to maintain suitable depth of anesthesia which relaxes the vocal band, avoids laryngeal spasms (reflex closure), reduces cardiovascular reaction and wakes up quickly after operation. Any factors that aggravate laryngeal obstruction and dyspnea should be avoided. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Approximately 4000 U.S. children undergo tracheostomy yearly [1], and these surgeries often result in hospital re-admissions that have definite cost and caregiver burdens due to complications that are avoidable with proper training and support. To assess the impact of a Family-Centered Care Coordination (FCCC) program on the quality of care received by children undergoing tracheostomy and their caregivers. Caregivers of children undergoing tracheostomies from January 2012 to January 2013 and then a different set of caregivers of children undergoing tracheostomies from January 2015 to January 2016 completed both the Pediatric Tracheostomy Health Status Instrument (PTHSI) 1 month after discharge and the Medical Complications Associated with Pediatric Tracheostomy (MCAT) questionnaire 6 months after initial tracheostomy. To assess complication rates, these same sets of caregivers were asked to complete the MCAT and only those who provided complete medical data for all 6 months were included for comparative analysis. The PTHSI and MCAT were administered at Massachusetts Eye and Ear in a hospital setting. Ten caregivers of children undergoing tracheostomies completed the PTHSI before FCCC program implementation and12 caregivers then completed the PTHSI after FCCC implementation. For each of the 2 groups, 5 caregivers provided complete data on the MCAT questionnaires. FCCC is a collection of programs, policies, and tools designed to ensure safe transition home for children undergoing tracheostomies, reduce re-admission rates, and minimize "caregiver burden". The PTHSI is a validated caregiver quality of life instrument that was supplemented by the MCAT which records post-discharge medical issues following tracheostomy that relate specifically to the tracheotomy placement. The time to first follow-up appointment decreased from 6.4 weeks (SD = 1.52) to 6 days (SD = 0.18) with FCCC implementation. The total MCAT scores decreased from 15.2 (SD = 1.1) to 1.3 (SD = 1.3) (Wilcoxon sum rank test: P < 0.016) whereas neither PTHSI scores (P = 0.32) nor the specific caregiver burden domain (P = 0.18) demonstrated a significant change. and Relevance: By reducing the time to first follow-up after tracheostomy and by optimizing caregiver tracheostomy tube care and teaching, children's quality of care and caregiver burden can be significantly improved.

The goal of this retrospective study is to compare the management and outcome of surgical treatment of laryngotracheal stenosis in children and infants with and without an associated neurological disorder. In a series of children operated on for subglottic stenosis (SGS), patients with an associated neurological disorder were identified. The following criteria were compared in children with and without neurological disease: grade of stenosis, age, technique (Crico-Tracheal Resection (CTR), Laryngo-Tracheo-Plasty (LTP) in single and 2 stage, laser), analyzing duration, preoperative tracheostomy, decannulation rate, preoperative gastrostomy, and number of days in intensive care unit and in hospital. Two hundred twenty-three children were operated on for subglottic stenosis, of whom 68 (30.5%) had an associated neurological disorder. Some criteria were found to be statistically different between the 2 populations: mean age of 43 months in neurological population versus 13 months (P < .001). The distribution of the grades of SGS appeared similar in the 2 groups (P = .088), and the mean duration of stay in hospital and in ICU were not statistically different (respectively, P = .186 and P = .056) between the 2 groups; a 2-stage procedure was performed more frequently than 1-stage in the cases with associated neurological disorder-66.6% versus 36.5% (P = .013); the median duration of stenting was 20 days in those with neurological disease versus 12 (P = .021). Preoperative tracheotomy was noted in 75% of neurological patients versus 47.7% of the others (P < .001). The outcome was considered to be good (decannulation and no further treatment) following a single procedure in 82.4% of patients with neurological disorder, as against 86.5% of neurologically unimpaired subjects. The difference in outcome of surgery was not statistically different (P = .392) between the 2 groups. It appears that subglottic stenosis in children with associated neurological disorder is not more severe than in neurologically normal patients. In three-quarters of the neurologically impaired cases, a preoperative tracheostomy was needed, but the rates of failure of postoperative decannulation are not statistically significant between the 2 groups. In our experience, 2-stage techniques are more often performed than single stage in this population in order to allow airway safety, for example after feeding. If properly managed, the final results are similar in the 2 populations. © The Author(s) 2016.

To review national trends in the management of pediatric airway foreign bodies (A-FBs) and esophageal foreign bodies (E-FBs) that obstruct the airway. Retrospective review using a national pediatric data set (Kids' Inpatient Database). Pediatric patients admitted across the United States during 2003. The Kids' Inpatient Database 2003 samples 2 984 129 pediatric discharges from 3438 hospitals in 36 states. The Kids' Inpatient Database 2003 was analyzed for A-FBs and E-FBs (International Classification of Diseases, Ninth Revision, Clinical Modification codes E911 and E912) in patients 20 years or younger, and weighted data are presented to facilitate national estimates. A total of 2771 patients (59% male) were admitted for an A-FB or an E-FB that was obstructing the airway. The mean (SE) age of the patients was 3.5 (0.17) years; 55% were younger than 2 years. The foreign bodies were classified as food (42%; mean age, 2.5 years) or other (58%; mean age, 4.3 years). The average length of stay was 6.4 days (median [SE], 1.5 [0.6] days), and the average number of procedures was 2.4 (median [SE], 1.3 [0.1] procedures). Seventy-one percent of the patients were treated at teaching hospitals. The mean (SD) total charges were $34 652 ($3543), with regional variation (P < .001). Children's hospitals (28%) had higher mean total charges than nonchildren's hospitals (P = .03); 3.4% of admissions died in the hospital (mean [SE] age, 4.6 [0.9] years), with an average length of stay of 11.7 (SE, 2.7) days and an average of 6.2 (SE, 0.7) procedures. Bronchoscopy (52%), esophagoscopy (28%), and tracheotomy (1.7%) were the primary procedures performed. The rates of positive FB findings for bronchoscopy and esophagoscopy were 37% and 46%, respectively. Pediatric A-FBs and E-FBs that obstruct the airway occur infrequently. Most of the patients are referred to teaching institutions. Among patients who were admitted with a diagnosis of airway obstruction from an A-FB or an E-FB, the rates of positive findings at surgery were 37% and 46%, respectively. A surprisingly high mortality rate was noted. Alternative education measures should be considered to train physicians in the management of this infrequent, potentially lethal condition.

Addiction to opium and heroin is not only an important social and individual problem in the world but it also affects the human physiology and multiple systems. The aim of this study is to determine the effects of chronic heroin consumption on basal and vagus electrical-stimulated total gastric acid and pepsin secretion in rats. The study was carried out in the Department of Physiology, Kerman University of Medical Sciences, Iran from August 2002 to June 2003. Both male and female rats weighing 200-250 g were used. Rats received daily doses of heroin intraperitoneally starting from 0.2 mg/kg to 0.1 mg/kg/day up to the maintenance level of 0.7 mg/kg and continued until day 12. After anesthesia, tracheotomy and laparotomy, gastric effluents were collected by washout technique with a 15 minutes interval. The total titrable acid was measured by manual titrator, and the total pepsin content was measured by Anson's method. Vagal electrical stimulation was used to stimulate the secretion of acid and pepsin. Heroin results in a significant decrease in total basal acid and pepsin secretions (4.10 +/- 0.18 mmol/15 minutes versus 2.40 +/- 0.16 mmol/15 minutes for acid, p<0.01, and 3.63 +/- 0.18 mg/15 minutes versus 3.11+/- 0.18 mg/15 minutes for pepsin, p<0.05). But, it does not produce any significant changes in acid and pepsin secretions in vagotomized condition. Heroin also causes a significant decrease in vagal-electrically stimulated acid and pepsin secretions (14.70 +/- 0.54 mmol/15 minutes versus 4.30 +/- 0.21 mmol/15 minutes for acid, p<0.01, and 3.92 +/-0.16 mg/15 minutes versus 3.37+/- 0.16 mg/15 minutes for pepsin, p<0.05). Heroin consumption decreases the total gastric basal and vagus stimulation of acid and pepsin secretion, but not in vagotomized condition. Heroin may decrease acid secretion by inhibiting vagal release of acetylcholine within the gastric wall. Other probable mechanisms include: presynaptic inhibition of acetylcholine release or depressing the vagal center, inhibition of pentagastrin induced acid secretion, inhibitory effects via central mechanisms, probably mediated by the opiate receptors. Further studies are needed to recognize the actual mechanism.

In mammals, olfactory sensation depends on inhalation, which controls activation of sensory neurons and temporal patterning of central activity. Odor representations by mitral and tufted (MT) cells, the main output from the olfactory bulb (OB), reflect sensory input as well as excitation and inhibition from OB circuits, which may change as sniff frequency increases. To test the impact of sampling frequency on MT cell odor responses, we obtained whole-cell recordings from MT cells in anesthetized male and female mice while varying inhalation frequency via tracheotomy, allowing comparison of inhalation-linked responses across cells. We characterized frequency effects on MT cell responses during inhalation of air and odorants using inhalation pulses and also "playback" of sniffing recorded from awake mice. Inhalation-linked changes in membrane potential were well predicted across frequency from linear convolution of 1 Hz responses; and, as frequency increased, near-identical temporal responses could emerge from depolarizing, hyperpolarizing, or multiphasic MT responses. However, net excitation was not well predicted from 1 Hz responses and varied substantially across MT cells, with some cells increasing and others decreasing in spike rate. As a result, sustained odorant sampling at higher frequencies led to increasing decorrelation of the MT cell population response pattern over time. Bulk activation of sensory inputs by optogenetic stimulation affected MT cells more uniformly across frequency, suggesting that frequency-dependent decorrelation emerges from odor-specific patterns of activity in the OB network. These results suggest that sampling behavior alone can reformat early sensory representations, possibly to optimize sensory perception during repeated sampling. SIGNIFICANCE STATEMENT Olfactory sensation in mammals depends on inhalation, which increases in frequency during active sampling of olfactory stimuli. We asked how inhalation frequency can shape the neural coding of odor information by recording from projection neurons of the olfactory bulb while artificially varying odor sampling frequency in the anesthetized mouse. We found that sampling an odor at higher frequencies led to diverse changes in net responsiveness, as measured by action potential output, that were not predicted from low-frequency responses. These changes led to a reorganization of the pattern of neural activity evoked by a given odorant that occurred preferentially during sustained, high-frequency inhalation. These results point to a novel mechanism for modulating early sensory representations solely as a function of sampling behavior. Copyright © 2018 the authors 0270-6474/18/382189-18$15.00/0.

Avoidance of excessive sedation and subsequent prolonged mechanical ventilation in intensive care units (ICUs) is recommended, but no data are available for critically ill postoperative patients. We hypothesised that in such patients stopping sedation immediately after admission to the ICU could reduce unnecessary sedation and improve patient outcomes. We did a randomised, parallel-group, clinical trial at three ICUs in France. Stratified randomisation with minimisation (1:1 via a restricted web platform) was used to assign eligible patients (aged ≥18 years, admitted to an ICU after abdominal surgery, and expected to require at least 12 h of mechanical ventilation because of a critical illness defined by a Sequential Organ Failure Assessment score >1 for any organ, but without severe acute respiratory distress syndrome or brain injury) to usual sedation care provided according to recommended practices (control group) or to immediate interruption of sedation (intervention group). The primary outcome was the time to successful extubation (defined as the time from randomisation to the time of extubation [or tracheotomy mask] for at least 48 h). All patients who underwent randomisation (except for those who were excluded after randomisation) were included in the intention-to-treat analysis. This study is registered with ClinicalTrials.gov, number NCT01486121. Between Dec 2, 2011, and Feb 27, 2014, 137 patients were randomly assigned to the control (n=68) or intervention groups (n=69). In the intention-to-treat analysis, time to successful extubation was significantly lower in the intervention group than in the control group (median 8 h [IQR 4-36] vs 50 h [29-93], group difference -33·6 h [95% CI -44·9 to -22·4]; p<0·0001). The adjusted hazard ratio was 5·2 (95% CI 3·1-8·8, p<0·0001). Immediate interruption of sedation in critically ill postoperative patients with organ dysfunction who were admitted to the ICU after abdominal surgery improved outcomes compared with usual sedation care. These findings support interruption of sedation in these patients following transfer from the operating room.

Change in reimbursement and costs in German oncological head and neck surgery over the last decade: ablative tongue cancer surgery and reconstruction with split-thickness skin graft vs. microvascular radial forearm flap.

PubMed

Hoefert, Sebastian; Lotter, Oliver

Defects after ablative tongue cancer surgery can be reconstructed by split-thickness skin grafts or free microvascular flaps. The different surgical options may influence costs, reimbursement, and therefore possible profits. Our goal was to analyze the development of these parameters for different procedures in head and neck reconstruction in Germany over the last decade. After tumor resection and neck dissection of tongue cancer, three different scenarios were chosen to calculate costs, reimbursement, length of stay (LoS), and profits. Two options considered were reconstruction by split-thickness skin graft with (option Ia) and without (option Ib) tracheotomy. In addition, we analyzed microvascular reconstruction with radial forearm flap (option II). Furthermore, unsatisfactory results after options Ia and Ib may make secondary tongue plastic with split-thickness skin grafting necessary (option I+). The calculations were performed considering the German Diagnosis Related Group (DRG) system and compared to the specific DRG cost data of 250 German reference hospitals. The overall average length of stay (aLoS) declined from 16.7 to 12.8 days with a reduction in every option. Until 2011, all options showed similar accumulated DRG reimbursement. From 2012 onwards, earnings almost doubled for option II due to changes in the DRG allocation. As was expected, the highest costs were observed in option II. Profits (reimbursement minus costs) were also highest for option II (mean 2052 €, maximum 3630 Euros in 2015) followed by options Ia (765 €) and Ib/I+ (681 €). Average profits over time would be 17 to 19% higher if adjusted for inflation. We showed the development of the DRG allocation of two commonly used methods of reconstruction after ablative tongue cancer surgery and the associated LoS, reimbursement, costs, and profits. As expected, the highest values were found for microvascular reconstruction. Microvascular reconstruction may also be the primary choice of treatment from a medical point of view. However, prolonged operation times, intensive care, and hospital stay in connection with complex microvascular operations can easily turn profits into losses as opposed to the results of simple, reliable, and fast split-thickness skin grafting. The inflation rate influences profits in reimbursement systems where costs are based on a previous period of time. Surgeons find themselves daily in an area of conflict between economic interests and medical decision-making. Due to its multidimensional aspects, the choice of the reconstructive technique should be primarily based on the best medical care for the patient. But there should also be awareness of the economic risk of all three surgical procedures.

To summarize the results and methods of left subclavian artery revascularization by stented trunk fenestration for acute Stanford type A aortic dissection. Clinical data of 67 patients (54 male and 13 female, mean age of (50±10) years) underwent surgical treatment of left subclavian artery fenestration for acute Stanford A aortic dissection in Department of Cardiothoracic Surgery, Changhai Hospital, Second Military Medical College between September 2008 and December 2014 were analyzed retrospectively. The origin of the left subclavian artery was in the true lumen and no dissection existed near the artery's starting. There were 18 cases of Marfan's syndrome. Preoperative echocardiography showed moderate to severe aortic regurgitation in 10 cases, and mitral regurgitation in 3 cases. Electrocardiogram showed myocardial ischemia in 5 cases. Three patients had acute impaired renal function. All the patients received total arch replacement combined with stented elephant trunk implantation. Left subclavian artery revascularization was performed by stented trunk fenestration as follows: firstly, stented elephant trunk was implanted to completely cover the left subclavian artery, then part of stented trunk's polyester lining was removed which is located at the origin of left subclavian artery. Aortic root procedures included aortic valve replacement in 2 cases, Bentall procedure in 21 cases and aortic valve sparing in 44 cases. Three patients received mitral valve repair and 6 patients received coronary artery bypass grafting. The cardiopulmonary bypass time, cross-clamp time, and circulatory arrest time were (179±32) minutes, (112±25) minutes, and (26±10) minutes, respectively. The in-hospital mortality was 7.5% (5/67): 2 patients died of multiple organ failure, 1 patient died of acute renal failure and another 2 patients died of severe infection shock. Two patients required reexploration for root bleeding. Transient neurology dysfunction developed in 6 patients. Six patients received tracheotomy and prolonged ventilation due to pulmonary infection. All patients discharged from the hospital were followed up for 1 to 5 years. During long-term follow-up, the survival rate was 100% and 89.8% at 1 and 5 years, respectively. CT angiography was performed once per year after discharged. The left subclavian artery perfusion was good. No dissection or anastomosis leakage was identified in any case. Stroke and left limb ischemia did not develope. For acute Stanford type A aortic dissection whose origin of the left subclavian artery is in the true lumen and no dissection existed near the artery's starting, the left subclavian artery revascularization by stented trunk fenestration technique during total arch replacement combined with stented elephant trunk implantation is reliable and effective.

Acetazolamide has been used for decades as a respiratory stimulant for patients with chronic obstructive pulmonary disease (COPD) and metabolic alkalosis, but no large randomized placebo-controlled trial is available to confirm this approach. To determine whether acetazolamide reduces mechanical ventilation duration in critically ill patients with COPD and metabolic alkalosis. The DIABOLO study, a randomized, double-blind, multicenter trial, was conducted from October 2011 through July 2014 in 15 intensive care units (ICUs) in France. A total of 382 patients with COPD who were expected to receive mechanical ventilation for more 24 hours were randomized to the acetazolamide or placebo group and 380 were included in an intention-to treat analysis. Acetazolamide (500-1000 mg, twice daily) vs placebo administered intravenously in cases of pure or mixed metabolic alkalosis, initiated within 48 hours of ICU admission and continued during the ICU stay for a maximum of 28 days. The primary outcome was the duration of invasive mechanical ventilation via endotracheal intubation or tracheotomy. Secondary outcomes included changes in arterial blood gas and respiratory parameters, weaning duration, adverse events, use of noninvasive ventilation after extubation, successful weaning, the duration of ICU stay, and in-ICU mortality. Among 382 randomized patients, 380 (mean age, 69 years; 272 men [71.6%]; 379 [99.7%] with endotracheal intubation) completed the study. For the acetazolamide group (n = 187), compared with the placebo group (n = 193), no significant between-group differences were found for median duration of mechanical ventilation (-16.0 hours; 95% CI, -36.5 to 4.0 hours; P = .17), duration of weaning off mechanical ventilation (-0.9 hours; 95% CI, -4.3 to 1.3 hours; P = .36), daily changes of minute-ventilation (-0.0 L/min; 95% CI, -0.2 to 0.2 L/min; P = .72), or partial carbon-dioxide pressure in arterial blood (-0.3 mm Hg; 95% CI, -0.8 to 0.2 mm Hg; P = .25), although daily changes of serum bicarbonate (between-group difference, -0.8 mEq/L; 95% CI, -1.2 to -0.5 mEq/L; P < .001) and number of days with metabolic alkalosis (between-group difference, -1; 95% CI, -2 to -1 days; P < .001) decreased significantly more in the acetazolamide group. Other secondary outcomes also did not differ significantly between groups. Among patients with COPD receiving invasive mechanical ventilation, the use of acetazolamide, compared with placebo, did not result in a statistically significant reduction in the duration of invasive mechanical ventilation. However, the magnitude of the difference was clinically important, and it is possible that the study was underpowered to establish statistical significance. clinicaltrials.gov Identifier: NCT01627639.

Greek Medicine Practice at Ancient Rome: The Physician Molecularist Asclepiades

Background: In the pre-Hellenistic period, the concept of medicine was not well-defined. Usually, a disease was considered as a divine punishment and its treatment was devolved to the priests who asked for healing from the divinities. The only job that could be compared to medical practice was a kind of itinerant medicine, derived from the Egyptian therapeutic tradition based only on practical experience and performed by people that knew a number of remedies, mostly vegetable, but without any theoretical bases about the possible mechanisms of action. Opinions about the human nature (naturalistic thinking) and the origin of the illness and heal were the basis of Greek medicine practiced by ancient priests of Asclepius. However, with the evolution of the thought for the continuous research of “κόσμος” (world) knowledge, philosophy woulld become an integral part of medicine and its evolution. This close relationship between philosophy and medicine is confirmed by the Greek physician Galen in the era of the Roman Empire. Methods: Philosophical thought looked for world knowledge starting from mathematics, physics, astronomy, chemistry, medicine, psychology, metaphysics, sociology, and ethics. We must keep in mind that, according to the ancient people, the physicians could not heal the patients without the aid of a “divine God” until medicine, thanks to the Hippocratic practice, became more independent from the supernatural, and contemporary, ethical, and professional. Many physicians were philosophers, as confirmed by their views of life, such as Hippocrates of Cos, Aristotle (hailed as the father of comparative anatomy and physiology), Pythagoras of Samos, Alcmaeon of Croton, Empedocles, Praxagoras, Erasistratus, Galen, and others, including Asclepiades of Bithynia (atomists affinity). Asclepiades, a Greek physician born in Prusa, studied in Athens and Alexandria. His thought was influenced by Democritus’ theories, refusing extensively the Hippocratic ideas that diseases are a result of mood imbalance. Results: Differing from the current Hippocratic idea, only in extreme cases he prescribed medications and bloodletting, two of the most-used therapies of that time. He usually prescribed therapies based on the Epicurean thought, then consisting of walks and music, massages, and thermal baths. He anticipated the modern idea of the body consisting of atoms, and believed that between the atoms exist empty spaces called pores. As the founder of the so called Methodist School, he was the first to divide acute and chronic diseases, and thought that body weakness was dependent on the excessive width of the pores, while their excessive shrinkage determines fever. According to his student Caelius Aurelianus he was the first to adopt tracheotomy as an emergency therapy for diphtheria. Conclusions: Although it is very difficult to reconstruct the theories of Asclepiades of Bithynia because of the lack of original texts, this paper attempts to focus his role and his thought in affirming the Greek medical practice in ancient Rome and to highlight his modernity.

To sedate the mechanically ventilation patients in intensive care unit (ICU) with stimulative circadian rhythm, and evaluate whether the protocol has advantages in recovering natural circadian rhythm, duration of mechanical ventilation, and length of ICU stay after weaning of sedation. A prospective random control trial was conducted. One hundred and twenty ventilated patients in ICU were randomly assigned to four groups: circadian rhythm (CR), daily interruption (DI), continuous sedation (CS) or demand sedation (DS) group, each n = 30. Given more complications, DS group was deleted after recruiting 10 cases and 90 patients were admitted ultimately. Patients' age, gender, body weight, acute physiology and chronic health evaluation II (APACHE II) scores, sedatives dosages, daily arousal time, duration of mechanical ventilation, length of ICU stay, complications (ventilator-associated pneumonia, barotrauma with intrathoracic drain tube) and untoward reactions (accidental extubation, reintubation, tracheotomy, death) were recorded, the biochemical indicators were determined, as well as number of nurses on duty at 10:00 and 22:00. The patients' sex ratio, age, body weight, APACHEII scores, duration of mechanical ventilation, length of ICU stay showed no difference among CR, DI and CS groups. The total sedatives dosages (mg: 5466.7 ± 620.4) and average sedatives dosages [mg×h(-1) ×kg(-1): 2.19 ± 0.61] in CS group were significantly higher than those in CR group (4344.5 ± 816.0, 1.00 ± 0.51) and DI group (4154.3 ± 649.4, 1.23 ± 0.62, all P < 0.01), and there was no difference between CR group and DI group. Daily arousal time in the CR group (hours: 4.40 ± 1.30) was significantly lengthened compared with that in DI group (0.59 ± 0.26) and CS group (0.15 ± 0.02, both P < 0.05). The complications showed no differences in each group, but incidences of the untoward reactions in DI group (2 cases) were significantly increased compared with that in CR group (1 case) and CS group (0 case, P = 0.0477). After weaning of sedation, patients with normal circadian rhythm were significantly more in CR group than that in CS group (19 vs. 9, P = 0.0339). Among CR group, DI group and CS group, there were significant differences in the numbers of nurses on duty in the daytime (1.65, 1.41, 1.14, all P < 0.01), but there was no difference in the night. The biochemistry index showed no difference in each group. It demonstrated that sedation with stimulative circadian rhythm be helpful to create circadian rhythm after weaning of sedation. While complications and untoward reactions did not increase, as well as duration of mechanical ventilation and length of ICU stay. Therefore, the clinical applicability of this sedative strategy was highlighted.

Pycnodysostosis is a rare autosomal, recessive, skeletal dysplasia caused by a mutation in the cathepsin k gene. Pycnodysostosis is characterized by short stature, characteristic facial appearance (delayed closure of fontanelles and cranial sutures, mandibular hypoplasia and angle disorder, blue sclera), and acroosteolysis of the distal phalanges. Our aim was to describe the otorhinolaryngologic findings, differential diagnoses, various treatment options, and followup in eight cases of pycnodysostosis. This retrospective clinical study used data from eight patients diagnosed with pycnodysostosis by a single pediatric endocrinologist primarily based on clinical and radiographic findings. All patients were referred to the otorhinolaryngology outpatient clinic by the pediatric endocrinology unit of the Marmara University between February 2013 and March 2015. Detailed medical histories were obtained in all cases and otorhinolaryngologic physical examination, blood assays, electrocardiogram, lateral skull X-rays, chest radiograph, cephalometric investigations, tympanograms, and audiograms were also carried out. Sleep videos of patients were recorded and those with upper airway problems were evaluated for sleep apnea by polysomnography. Informed consent form was obtained from the parents of all patients. Eight patients (7 females and 1 male) displaying proportionate dwarfism were included in the study. They had a mean age of 14.7 years (range: 13-16 y), the mean height of 141.3 cm (range 132-155 cm), and mean weight of 44.4 kg (range: 39.6-49.3 kg). All patients had facial dysmorphism with frontal bossing and the hands and feet had short digits with overlying cutaneous wrinkles that tapered off with large overriding nails. Midfacial hypoplasia and malocclusion were observed in seven of the eight patients (87.5%), four (50%) had micrognathia, and five (62.5%) had proptosis. Tympanograms and audiograms of all patients were type A and normal, and the mean of the pure tone audiogram was 13.3 dB (range: 10-16 dB). All patients had a narrow and grooved palate with disturbed dentition; two of them (25%) had mild markedness of the tongue base, five (62.5%) had grade 3 and three (37.5%) had grade 2 tonsillar hypertrophy, and five (62.5%) had adenoid hypertrophy. One patient (12.5%) had grade 3 Mallampati, four (50%) showed grade 2 Mallampati while three (37.5%) patients displayed grade 1 Mallampati score. Further, while six (75%) patients had no uvular pathology, one (12.5%) patient presented with uvular elongation and another patient had a bifid uvula. Cephalometric measurements such as PAS-UP (mean 5.67 mm; range: 5.0-7.6 mm) and PAS-TP (mean 9.61 mm; range: 8.5-12.2 mm) were lower than that of normal subjects. Video recordings showed that six of the eight patients (75%) had respiratory distress and four (50%) had sleep apnea. Polysomnography in these patients with sleep apnea showed that two had mild OSA (AHI: 18.2 and 20.1 events/hour) and two had severe OSA (AHI: 53.4 and 62.8 events/hour). For upper airway problems, an adenotonsillectomy was performed in two (25%) patients while two others required an adenoidectomy. Positive pressure ventilation was recommended in two patients with persistent sleep apnea after adeno/adenotonsillectomy. However, because of the parental objections, the follow-up polysomnographs could not be obtained. Pycnodysostosis is a very rare form of bone dysplasia. Otorhinolaryngologically, proper follow-up of these patients and appropriate treatment of upper airway problems are important to achieve an acceptable quality of life. Adeno/adenotonsillectomy and positive pressure ventilation, used as conservative approaches in treating upper airway problems, are effective and could be used instead of an aggressive surgery such as tracheotomy or maxillomandibular advancement. This study, to the best of our knowledge, is the largest ENT case series on pycnodysostosis. Copyright © 2017 Elsevier B.V. All rights reserved.

To evaluate the efficacy and safety of short-term deep sedation strategy in patients with spontaneous intracerebral hemorrhage (ICH) after surgery. A perspective, randomized, parallel-group study was conducted. Adult patients with spontaneous ICH and undergoing craniotomy admitted to Daxing Teaching Hospital of Capital Medical University from December 2015 to November 2016 were enrolled. The patients who received surgery were randomly divided into a short-term deep sedation and a slight and middle sedation group. Sufentanil was used as an analgesic drug in all patients and midazolam was used as a sedative after the operation. The patients in the slight and middle sedation group received midazolam 0.05-0.10 mg/kg with a goal of mild sedation [Richmond agitation and sedation scale (RASS) score of -2-1]. The patients in the short-term deep sedation group received midazolam 0.1-0.2 mg/kg with a goal of deep sedation (RASS score of -4 to -3) and a duration of no more than 12 hours. Postoperative sedation, blood pressure changes, laboratory indexes, residual hematoma and clinical outcomes were recorded in two groups. During the study, a total of 183 patients with spontaneous ICH were collected, excluding who was older than 65 years, with shock, and with preoperative Glasgow coma score (GCS) of 3. 106 patients were enrolled in this study, and 53 patients were assigned to the short-term deep sedation group and slight and middle sedation group, respectively. In the slight and middle sedation group, 4 patients received reoperation because of repeated hemorrhage and no patient operated repeatedly in the short-term deep sedation group, and there was a significant difference between the two groups (χ 2 = 4.000, P = 0.045). The number of patients undergoing tracheotomy in the short-term deep sedation group was significantly lower than that in the slight and middle sedation group (9 cases vs. 21 cases, P < 0.05). RASS score within 12 hours after operation of the patients in the short-term deep sedation group was lower than that in slight and middle sedation group [-4 (-4, -2) vs. -2 (-3, -1) at 4 hours, -4 (-4, -2) vs. -1 (-2, 0) at 8 hours, -3 (-4, -2) vs. 0 (-2, 1) at 12 hours, all P < 0.01], sudden restlessness was significantly reduced [times: 1 (0, 1) vs. 3 (2, 3), P < 0.01], and postoperative sedation duration was significantly prolonged [hours: 14.0 (8.3, 20.8) vs. 8.9 (3.4, 15.3), P < 0.05]. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) within 12 hours after operation in the short-term deep sedation group were significantly lower than those of the slight and middle sedation group [SBP (mmHg, 1 mmHg = 0.133 kPa): 136.8±30.5 vs. 149.1±33.5, DBP (mmHg): 85.0 (70.8, 102.3) vs. 89.0 (69.2, 116.7), both P < 0.05]. There were no significant differences in the arterial blood gas, routine blood test or coagulation function between the two groups at 24 hours after operation. The volume of residual hematoma at 2, 7 and 14 days after operation in the short-term deep sedation group was significantly decreased as compared with slight and middle sedation group (mL: 16.4±15.6 vs. 38.2±22.2 at 2 days, 9.6±8.7 vs. 20.6±18.6 at 7 days, 1.2±1.0 vs. 4.4±3.6 at 14 days, all P < 0.05), number of deaths in 3 months were significantly less (5 cases vs. 13 cases), and the patients with favorable prognosis were increased significantly (39 cases vs. 12 cases, both P < 0.05). The study results showed that short-term deep sedation strategy after surgery can reduce the incidence of adverse events and improve the prognosis of patients with spontaneous ICH, so it is safe and effective.

Noninvasive Positive Pressure Ventilation for Acute Respiratory Failure Patients With Chronic Obstructive Pulmonary Disease (COPD)

Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html. Chronic Obstructive Pulmonary Disease (COPD) Evidentiary Framework Influenza and Pneumococcal Vaccinations for Patients With Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Smoking Cessation for Patients With Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Community-Based Multidisciplinary Care for Patients With Stable Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Pulmonary Rehabilitation for Patients With Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Long-term Oxygen Therapy for Patients With Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Noninvasive Positive Pressure Ventilation for Acute Respiratory Failure Patients With Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Noninvasive Positive Pressure Ventilation for Chronic Respiratory Failure Patients With Stable Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Hospital-at-Home Programs for Patients With Acute Exacerbations of Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Home Telehealth for Patients With Chronic Obstructive Pulmonary Disease (COPD): An Evidence-Based Analysis Cost-Effectiveness of Interventions for Chronic Obstructive Pulmonary Disease Using an Ontario Policy Model Experiences of Living and Dying With COPD: A Systematic Review and Synthesis of the Qualitative Empirical Literature For more information on the qualitative review, please contact Mita Giacomini at: http://fhs.mcmaster.ca/ceb/faculty_member_giacomini.htm. For more information on the economic analysis, please visit the PATH website: http://www.path-hta.ca/About-Us/Contact-Us.aspx. The Toronto Health Economics and Technology Assessment (THETA) collaborative has produced an associated report on patient preference for mechanical ventilation. For more information, please visit the THETA website: http://theta.utoronto.ca/static/contact. Objective The objective of this evidence-based analysis was to examine the effectiveness, safety, and cost-effectiveness of noninvasive positive pressure ventilation (NPPV) in the following patient populations: patients with acute respiratory failure (ARF) due to acute exacerbations of chronic obstructive pulmonary disease (COPD); weaning of COPD patients from invasive mechanical ventilation (IMV); and prevention of or treatment of recurrent respiratory failure in COPD patients after extubation from IMV. Clinical Need and Target Population Acute Hypercapnic Respiratory Failure Respiratory failure occurs when the respiratory system cannot oxygenate the blood and/or remove carbon dioxide from the blood. It can be either acute or chronic and is classified as either hypoxemic (type I) or hypercapnic (type II) respiratory failure. Acute hypercapnic respiratory failure frequently occurs in COPD patients experiencing acute exacerbations of COPD, so this is the focus of this evidence-based analysis. Hypercapnic respiratory failure occurs due to a decrease in the drive to breathe, typically due to increased work to breathe in COPD patients. Technology There are several treatment options for ARF. Usual medical care (UMC) attempts to facilitate adequate oxygenation and treat the cause of the exacerbation, and typically consists of supplemental oxygen, and a variety of medications such as bronchodilators, corticosteroids, and antibiotics. The failure rate of UMC is high and has been estimated to occur in 10% to 50% of cases. The alternative is mechanical ventilation, either invasive or noninvasive. Invasive mechanical ventilation involves sedating the patient, creating an artificial airway through endotracheal intubation, and attaching the patient to a ventilator. While this provides airway protection and direct access to drain sputum, it can lead to substantial morbidity, including tracheal injuries and ventilator-associated pneumonia (VAP). While both positive and negative pressure noninvasive ventilation exists, noninvasive negative pressure ventilation such as the iron lung is no longer in use in Ontario. Noninvasive positive pressure ventilation provides ventilatory support through a facial or nasal mask and reduces inspiratory work. Noninvasive positive pressure ventilation can often be used intermittently for short periods of time to treat respiratory failure, which allows patients to continue to eat, drink, talk, and participate in their own treatment decisions. In addition, patients do not require sedation, airway defence mechanisms and swallowing functions are maintained, trauma to the trachea and larynx are avoided, and the risk for VAP is reduced. Common complications are damage to facial and nasal skin, higher incidence of gastric distension with aspiration risk, sleeping disorders, and conjunctivitis. In addition, NPPV does not allow direct access to the airway to drain secretions and requires patients to cooperate, and due to potential discomfort, compliance and tolerance may be low. In addition to treating ARF, NPPV can be used to wean patients from IMV through the gradual removal of ventilation support until the patient can breathe spontaneously. Five to 30% of patients have difficultly weaning. Tapering levels of ventilatory support to wean patients from IMV can be achieved using IMV or NPPV. The use of NPPV helps to reduce the risk of VAP by shortening the time the patient is intubated. Following extubation from IMV, ARF may recur, leading to extubation failure and the need for reintubation, which has been associated with increased risk of nosocomial pneumonia and mortality. To avoid these complications, NPPV has been proposed to help prevent ARF recurrence and/or to treat respiratory failure when it recurs, thereby preventing the need for reintubation. Research Questions What is the effectiveness, cost-effectiveness, and safety of NPPV for the treatment of acute hypercapnic respiratory failure due to acute exacerbations of COPD compared with usual medical care, and invasive mechanical ventilation? What is the effectiveness, cost-effectiveness, and safety of NPPV compared with IMV in COPD patients after IMV for the following purposes: weaning COPD patients from IMV, preventing ARF in COPD patients after extubation from IMV, and treating ARF in COPD patients after extubation from IMV? Research Methods Literature Search A literature search was performed on December 3, 2010 using OVID MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, OVID EMBASE, the Cumulative Index to Nursing & Allied Health Literature (CINAHL), Wiley Cochrane, and the Centre for Reviews and Dissemination/International Agency for Health Technology Assessment (INAHTA) for studies published from January 1, 2004 until December 3, 2010. Abstracts were reviewed by a single reviewer and, for those studies meeting the eligibility criteria, full-text articles were obtained. Reference lists were also examined for any additional relevant studies not identified through the search. Since there were numerous studies that examined the effectiveness of NPPV for the treatment of ARF due to exacerbations of COPD published before 2004, pre-2004 trials which met the inclusion/exclusion criteria for this evidence-based review were identified by hand-searching reference lists of included studies and systematic reviews. Inclusion Criteria English language full-reports; health technology assessments, systematic reviews, meta-analyses, and randomized controlled trials (RCTs); studies performed exclusively in patients with a diagnosis of COPD or studies performed with patients with a mix of conditions if results are reported for COPD patients separately; patient population: (Question 1) patients with acute hypercapnic respiratory failure due to an exacerbation of COPD; (Question 2a) COPD patients being weaned from IMV; (Questions 2b and 2c) COPD patients who have been extubated from IMV. Exclusion Criteria < 18 years of age animal studies duplicate publications grey literature studies examining noninvasive negative pressure ventilation studies comparing modes of ventilation studies comparing patient-ventilation interfaces studies examining outcomes not listed below, such as physiologic effects including heart rate, arterial blood gases, and blood pressure Outcomes of Interest mortality intubation rates length of stay (intensive care unit [ICU] and hospital) health-related quality of life breathlessness duration of mechanical ventilation weaning failure complications NPPV tolerance and compliance Statistical Methods When possible, results were pooled using Review Manager 5 Version 5.1, otherwise, the results were summarized descriptively. Dichotomous data were pooled into relative risks using random effects models and continuous data were pooled using weighted mean differences with a random effects model. Analyses using data from RCTs were done using intention-to-treat protocols; P values < 0.05 were considered significant. A priori subgroup analyses were planned for severity of respiratory failure, location of treatment (ICU or hospital ward), and mode of ventilation with additional subgroups as needed based on the literature. Post hoc sample size calculations were performed using STATA 10.1. Quality of Evidence The quality of each included study was assessed taking into consideration allocation concealment, randomization, blinding, power/sample size, withdrawals/dropouts, and intention-to-treat analyses. The quality of the body of evidence was assessed as high, moderate, low, or very low according to the GRADE Working Group criteria. The following definitions of quality were used in grading the quality of the evidence: High Further research is very unlikely to change confidence in the estimate of effect. Moderate Further research is likely to have an important impact on confidence in the estimate of effect and may change the estimate. Low Further research is very likely to have an important impact on confidence in the estimate of effect and is likely to change the estimate. Very Low Any estimate of effect is very uncertain. Summary of Findings NPPV for the Treatment of ARF due to Acute Exacerbations of COPD NPPV Plus Usual Medical Care Versus Usual Medical Care Alone for First Line Treatment A total of 1,000 participants were included in 11 RCTs1; the sample size ranged from 23 to 342. The mean age of the participants ranged from approximately 60 to 72 years of age. Based on either the Global Initiative for Chronic Obstructive Lung Disease (GOLD) COPD stage criteria or the mean percent predicted forced expiratory volume in 1 second (FEV1), 4 of the studies included people with severe COPD, and there was inadequate information to classify the remaining 7 studies by COPD severity. The severity of the respiratory failure was classified into 4 categories using the study population mean pH level as follows: mild (pH ≥ 7.35), moderate (7.30 ≤ pH < 7.35), severe (7.25 ≤ pH < 7.30), and very severe (pH < 7.25). Based on these categories, 3 studies included patients with a mild respiratory failure, 3 with moderate respiratory failure, 4 with severe respiratory failure, and 1 with very severe respiratory failure. The studies were conducted either in the ICU (3 of 11 studies) or general or respiratory wards (8 of 11 studies) in hospitals, with patients in the NPPV group receiving bilevel positive airway pressure (BiPAP) ventilatory support, except in 2 studies, which used pressure support ventilation and volume cycled ventilation, respectively. Patients received ventilation through nasal, facial, or oronasal masks. All studies specified a protocol or schedule for NPPV delivery, but this varied substantially across the studies. For example, some studies restricted the amount of ventilation per day (e.g., 6 hours per day) and the number of days it was offered (e.g., maximum of 3 days); whereas, other studies provided patients with ventilation for as long as they could tolerate it and recommended it for much longer periods of time (e.g., 7 to 10 days). These differences are an important source of clinical heterogeneity between the studies. In addition to NPPV, all patients in the NPPV group also received UMC. Usual medical care varied between the studies, but common medications included supplemental oxygen, bronchodilators, corticosteroids, antibiotics, diuretics, and respiratory stimulators. The individual quality of the studies ranged. Common methodological issues included lack of blinding and allocation concealment, and small sample sizes. Need for Endotracheal Intubation Eleven studies reported the need for endotracheal intubation as an outcome. The pooled results showed a significant reduction in the need for endotracheal intubation in the NPPV plus UMC group compared with the UMC alone group (relative risk [RR], 0.38; 95% confidence interval [CI], 0.28−0.50). When subgrouped by severity of respiratory failure, the results remained significant for the mild, severe, and very severe respiratory failure groups. GRADE: moderate Inhospital Mortality Nine studies reported inhospital mortality as an outcome. The pooled results showed a significant reduction in inhospital mortality in the NPPV plus UMC group compared with the UMC group (RR, 0.53; 95% CI, 0.35−0.81). When subgrouped by severity of respiratory failure, the results remained significant for the moderate and severe respiratory failure groups. GRADE: moderate Hospital Length of Stay Eleven studies reported hospital length of stay (LOS) as an outcome. The pooled results showed a significant decrease in the mean length of stay for the NPPV plus UMC group compared with the UMC alone group (weighted mean difference [WMD], −2.68 days; 95% CI, −4.41 to −0.94 days). When subgrouped by severity of respiratory failure, the results remained significant for the mild, severe, and very severe respiratory failure groups. GRADE: moderate Complications Five studies reported complications. Common complications in the NPPV plus UMC group included pneumonia, gastrointestinal disorders or bleeds, skin abrasions, eye irritation, gastric insufflation, and sepsis. Similar complications were observed in the UMC group including pneumonia, sepsis, gastrointestinal disorders or bleeds, pneumothorax, and complicated endotracheal intubations. Many of the more serious complications in both groups occurred in those patients who required endotracheal intubation. Three of the studies compared complications in the NPPV plus UMC and UMC groups. While the data could not be pooled, overall, the NPPV plus UMC group experienced fewer complications than the UMC group. GRADE: low Tolerance/Compliance Eight studies reported patient tolerance or compliance with NPPV as an outcome. NPPV intolerance ranged from 5% to 29%. NPPV tolerance was generally higher for patients with more severe respiratory failure. Compliance with the NPPV protocol was reported by 2 studies, which showed compliance decreases over time, even over short periods such as 3 days. NPPV Versus IMV for the Treatment of Patients Who Failed Usual Medical Care A total of 205 participants were included in 2 studies; the sample sizes of these studies were 49 and 156. The mean age of the patients was 71 to 73 years of age in 1 study, and the median age was 54 to 58 years of age in the second study. Based on either the GOLD COPD stage criteria or the mean percent predicted FEV1, patients in 1 study had very severe COPD. The COPD severity could not be classified in the second study. Both studies had study populations with a mean pH less than 7.23, which was classified as very severe respiratory failure in this analysis. One study enrolled patients with ARF due to acute exacerbations of COPD who had failed medical therapy. The patient population was not clearly defined in the second study, and it was not clear whether they had to have failed medical therapy before entry into the study. Both studies were conducted in the ICU. Patients in the NPPV group received BiPAP ventilatory support through nasal or full facial masks. Patients in the IMV group received pressure support ventilation. Common methodological issues included small sample size, lack of blinding, and unclear methods of randomization and allocation concealment. Due to the uncertainty about whether both studies included the same patient population and substantial differences in the direction and significance of the results, the results of the studies were not pooled. Mortality Both studies reported ICU mortality. Neither study showed a significant difference in ICU mortality between the NPPV and IMV groups, but 1 study showed a higher mortality rate in the NPPV group (21.7% vs. 11.5%) while the other study showed a lower mortality rate in the NPPV group (5.1% vs. 6.4%). One study reported 1-year mortality and showed a nonsignificant reduction in mortality in the NPPV group compared with the IMV group (26.1% vs. 46.1%). GRADE: low to very low Intensive Care Unit Length of Stay Both studies reported LOS in the ICU. The results were inconsistent. One study showed a statistically significant shorter LOS in the NPPV group compared with the IMV group (5 ± 1.35 days vs. 9.29 ± 3 days; P < 0.001); whereas, the other study showed a nonsignificantly longer LOS in the NPPV group compared with the IMV group (22 ± 19 days vs. 21 ± 20 days; P = 0.86). GRADE: very low Duration of Mechanical Ventilation Both studies reported the duration of mechanical ventilation (including both invasive and noninvasive ventilation). The results were inconsistent. One study showed a statistically significant shorter duration of mechanical ventilation in the NPPV group compared with the IMV group (3.92 ± 1.08 days vs. 7.17 ± 2.22 days; P < 0.001); whereas, the other study showed a nonsignificantly longer duration of mechanical ventilation in the NPPV group compared with the IMV group (16 ± 19 days vs. 15 ± 21 days; P = 0.86). GRADE: very low Complications Both studies reported ventilator-associated pneumonia and tracheotomies. Both showed a reduction in ventilator-associated pneumonia in the NPPV group compared with the IMV group, but the results were only significant in 1 study (13% vs. 34.6%, P = 0.07; and 6.4% vs. 37.2%, P < 0.001, respectively). Similarly, both studies showed a reduction in tracheotomies in the NPPV group compared with the IMV group, but the results were only significant in 1 study (13% vs. 23.1%, P = 0.29; and 6.4% vs. 34.6%; P < 0.001). GRADE: very low Other Outcomes One of the studies followed patients for 12 months. At the end of follow-up, patients in the NPPV group had a significantly lower rate of needing de novo oxygen supplementation at home. In addition, the IMV group experienced significant increases in functional limitations due to COPD, while no increase was seen in the NPPV group. Finally, no significant differences were observed for hospital readmissions, ICU readmissions, and patients with an open tracheotomy, between the NPPV and IMV groups. NPPV for Weaning COPD Patients From IMV A total of 80 participants were included in the 2 RCTs; the sample sizes of the studies were 30 and 50 patients. The mean age of the participants ranged from 58 to 69 years of age. Based on either the GOLD COPD stage criteria or the mean percent predicted FEV1, both studies included patients with very severe COPD. Both studies also included patients with very severe respiratory failure (mean pH of the study populations was less than 7.23). Chronic obstructive pulmonary disease patients receiving IMV were enrolled in the study if they failed a T-piece weaning trial (spontaneous breathing test), so they could not be directly extubated from IMV. Both studies were conducted in the ICU. Patients in the NPPV group received weaning using either BiPAP or pressure support ventilation NPPV through a face mask, and patients in the IMV weaning group received pressure support ventilation. In both cases, weaning was achieved by tapering the ventilation level. The individual quality of the studies ranged. Common methodological problems included unclear randomization methods and allocation concealment, lack of blinding, and small sample size. Mortality Both studies reported mortality as an outcome. The pooled results showed a significant reduction in ICU mortality in the NPPV group compared with the IMV group (RR, 0.47; 95% CI, 0.23−0.97; P = 0.04). GRADE: moderate Intensive Care Unit Length of Stay Both studies reported ICU LOS as an outcome. The pooled results showed a nonsignificant reduction in ICU LOS in the NPPV group compared with the IMV group (WMD, −5.21 days; 95% CI, −11.60 to 1.18 days). GRADE: low Duration of Mechanical Ventilation Both studies reported duration of mechanical ventilation (including both invasive and noninvasive ventilation) as an outcome. The pooled results showed a nonsignificant reduction in duration of mechanical ventilation (WMD, −3.55 days; 95% CI, −8.55 to 1.44 days). GRADE: low Nosocomial Pneumonia Both studies reported nosocominal pneumonia as an outcome. The pooled results showed a significant reduction in nosocomial pneumonia in the NPPV group compared with the IMV group (RR, 0.14; 95% CI, 0.03−0.71; P = 0.02). GRADE: moderate Weaning Failure One study reported a significant reduction in weaning failure in the NPPV group compared with the IMV group, but the results were not reported in the publication. In this study, 1 of 25 patients in the NPPV group and 2 of 25 patients in the IMV group could not be weaned after 60 days in the ICU. NPPV After Extubation of COPD Patients From IMV The literature was reviewed to identify studies examining the effectiveness of NPPV compared with UMC in preventing recurrence of ARF after extubation from IMV or treating acute ARF which has recurred after extubation from IMV. No studies that included only COPD patients or reported results for COPD patients separately were identified for the prevention of ARF postextubation. One study was identified for the treatment of ARF in COPD patients that recurred within 48 hours of extubation from IMV. This study included 221 patients, of whom 23 had COPD. A post hoc subgroup analysis was conducted examining the rate of reintubation in the COPD patients only. A nonsignificant reduction in the rate of reintubation was observed in the NPPV group compared with the UMC group (7 of 14 patients vs. 6 of 9 patients, P = 0.67). GRADE: low Conclusions NPPV Plus UMC Versus UMC Alone for First Line Treatment of ARF due to Acute Exacerbations of COPD Moderate quality of evidence showed that compared with UMC, NPPV plus UMC significantly reduced the need for endotracheal intubation, inhospital mortality, and the mean length of hospital stay. Low quality of evidence showed a lower rate of complications in the NPPV plus UMC group compared with the UMC group. NPPV Versus IMV for the Treatment of ARF in Patients Who Have Failed UMC Due to inconsistent and low to very low quality of evidence, there was insufficient evidence to draw conclusions on the comparison of NPPV versus IMV for patients who failed UMC. NPPV for Weaning COPD Patients From IMV Moderate quality of evidence showed that weaning COPD patients from IMV using NPPV results in significant reductions in mortality, nosocomial pneumonia, and weaning failure compared with weaning with IMV. Low quality of evidence showed a nonsignificant reduction in the mean LOS and mean duration of mechanical ventilation in the NPPV group compared with the IMV group. NPPV for the Treatment of ARF in COPD Patients After Extubation From IMV Low quality of evidence showed a nonsignificant reduction in the rate of reintubation in the NPPV group compared with the UMC group; however, there was inadequate evidence to draw conclusions on the effectiveness of NPPV for the treatment of ARF in COPD patients after extubation from IMV PMID:23074436
