Initial experience with CytoSorb therapy in patients receiving left ventricular assist devices.

BACKGROUND: The use of left ventricular assist devices (LVAD) in patients with advance heart failure is still associated with an important risk of immune dysregulation and infections. The aim of this study was to determine whether extracorporeal blood purification using the CytoSorb device benefits patients after LVAD implantation in terms of complications and overall survival. MATERIALS AND METHODS: Between August 2010 and January 2020, 207 consecutive patients underwent LVAD implantation, of whom 72 underwent CytoSorb therapy and 135 did not. Overall survival, major adverse events, and laboratory parameters were compared between 112 propensity score-matched patients (CytoSorb: 72 patients; non-CytoSorb: 40 patients). RESULTS: WBC (p = .033), CRP (p = .001), and IL-6 (p < .001), significantly increased with LVAD implantation, while CytoSorb did not influence this response. In-hospital mortality and overall survival during follow-up were similar with CytoSorb. However, patients treated with CytoSorb were more likely to develop respiratory failure (54.2% vs. 30.0%, p = .024), need mechanical ventilation for longer than 6 days post-implant (50.0% vs. 27.5%, p = .035), and require tracheostomy during hospitalization (31.9% vs. 12.5%, p = .040). No other significant differences were observed with regard to major adverse events during follow-up. CONCLUSIONS: Overall, our results showed that CytoSorb might not convey a significant morbidity or mortality benefit for patients undergoing LVAD implantation.

Clinical predictors of prognosis in patients with traumatic brain injury combined with extracranial trauma.

Objective: The purpose of this study was to investigate whether routine blood tests on admission and clinical characteristics can predict prognosis in patients with traumatic brain injury (TBI) combined with extracranial trauma. Methods: Clinical data of 182 patients with TBI combined with extracranial trauma from April 2018 to December 2019 were retrospectively collected and analyzed. Based on GOSE score one month after discharge, the patients were divided into a favorable group (GOSE 1-4) and unfavorable group (GOSE 5-8). Routine blood tests on admission and clinical characteristics were recorded. Results: Overall, there were 48 (26.4%) patients with unfavorable outcome and 134 (73.6%) patients with favorable outcome. Based on multivariate analysis, independent risk factors associated with unfavorable outcome were age (odds ratio [OR], 1.070; 95% confidence interval [CI], 1.018-1.124; p<0.01), admission Glasgow Coma Scale (GCS) score (OR, 0.807; 95% CI, 0.675-0.965; p<0.05), heart rate (OR, 1.035; 95% CI, 1.004-1.067; p<0.05), platelets count (OR, 0.982; 95% CI, 0.967-0.997; p<0.05), and tracheotomy (OR, 15.201; 95% CI, 4.121-56.078; p<0.001). Areas under the curve (AUC) of age, admission GCS, heart rate, tracheotomy, and platelets count were 0.678 (95% CI, 0.584-0.771), 0.799 (95% CI, 0.723-0.875), 0.652 (95% CI, 0.553-0.751), 0.776 (95% CI, 0.692-0.859), and 0.688 (95% CI, 0.606-0.770), respectively. Conclusions: Age, admission GCS score, heart rate, tracheotomy, and platelets count can be recognized as independent predictors of clinical prognosis in patients with severe TBI combined with extracranial trauma.

Utility of sleep nasendoscopy versus microlaryngotracheobronchoscopy in the diagnosis of paediatric upper airway obstruction.

OBJECTIVE: To describe the utility of sleep nasendoscopy in determining the level of upper airway obstruction compared to microlaryngotracheobronchoscopy. METHODS: A retrospective observational study was conducted at a tertiary level paediatric hospital. Patients clinically diagnosed with upper airway obstruction warranting surgical intervention (i.e. with obstructive sleep apnoea or laryngomalacia) were included. These patients underwent sleep nasendoscopy in the anaesthetic room; microlaryngotracheobronchoscopy was subsequently performed and findings were compared. RESULTS: Twenty-seven patients were included in the study. Sleep nasendoscopy was able to induce stridor or stertor, and to detect obstruction at the level of palate and pharynx, including tongue base collapse, that was not observed with microlaryngotracheobronchoscopy. Only 47 per cent of patients who had prolapse or indrawing of arytenoids on sleep nasendoscopy had similar findings on microlaryngotracheobronchoscopy. However, microlaryngotracheobronchoscopy was better in diagnosing shortened aryepiglottic folds. CONCLUSION: This study demonstrates the utility of sleep nasendoscopy in determining the level and severity of obstruction by mimicking physiological sleep dynamics of the upper airway.

Evolution Over Time of Ventilatory Management and Outcome of Patients With Neurologic Disease.

OBJECTIVES: To describe the changes in ventilator management over time in patients with neurologic disease at ICU admission and to estimate factors associated with 28-day hospital mortality. DESIGN: Secondary analysis of three prospective, observational, multicenter studies. SETTING: Cohort studies conducted in 2004, 2010, and 2016. PATIENTS: Adult patients who received mechanical ventilation for more than 12 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Among the 20,929 patients enrolled, we included 4,152 (20%) mechanically ventilated patients due to different neurologic diseases. Hemorrhagic stroke and brain trauma were the most common pathologies associated with the need for mechanical ventilation. Although volume-cycled ventilation remained the preferred ventilation mode, there was a significant (p < 0.001) increment in the use of pressure support ventilation. The proportion of patients receiving a protective lung ventilation strategy was increased over time: 47% in 2004, 63% in 2010, and 65% in 2016 (p < 0.001), as well as the duration of protective ventilation strategies: 406 days per 1,000 mechanical ventilation days in 2004, 523 days per 1,000 mechanical ventilation days in 2010, and 585 days per 1,000 mechanical ventilation days in 2016 (p < 0.001). There were no differences in the length of stay in the ICU, mortality in the ICU, and mortality in hospital from 2004 to 2016. Independent risk factors for 28-day mortality were age greater than 75 years, Simplified Acute Physiology Score II greater than 50, the occurrence of organ dysfunction within first 48 hours after brain injury, and specific neurologic diseases such as hemorrhagic stroke, ischemic stroke, and brain trauma. CONCLUSIONS: More lung-protective ventilatory strategies have been implemented over years in neurologic patients with no effect on pulmonary complications or on survival. We found several prognostic factors on mortality such as advanced age, the severity of the disease, organ dysfunctions, and the etiology of neurologic disease.

Tracheotomy Outcomes in 64 Ventilated COVID-19 Patients at a High-Volume Center in Bronx, NY.

OBJECTIVES/HYPOTHESIS: The COVID-19 pandemic has resulted in a dramatic increase in the number of patients requiring prolonged mechanical ventilation. Few studies have reported COVID-19 specific tracheotomy outcomes, and the optimal timing and patient selection criteria for tracheotomy remains undetermined. We delineate our outcomes for tracheotomies performed on COVID-19 patients during the peak of the pandemic at a major epicenter in the United States. METHODS: This is a retrospective observational cohort study. Mortality, ventilation liberation rate, complication rate, and decannulation rate were analyzed. RESULTS: Sixty-four patients with COVID-19 underwent tracheotomy between April 1, 2020 and May 19, 2020 at two tertiary care hospitals in Bronx, New York. The average duration of intubation prior to tracheotomy was 20 days ((interquartile range [IQR] 16.5-26.0). The mortality rate was 33% (n = 21), the ventilation liberation rate was 47% (n = 30), the decannulation rate was 28% (n = 18), and the complication rate was 19% (n = 12). Tracheotomies performed by Otolaryngology were associated with significantly improved survival (P < .05) with 60% of patients alive at the conclusion of the study compared to 9%, 12%, and 19% of patients undergoing tracheotomy performed by Critical Care, General Surgery, and Pulmonology, respectively. CONCLUSIONS: So far, this is the second largest study describing tracheotomy outcomes in COVID-19 patients in the United States. Our early outcomes demonstrate successful ventilation liberation and decannulation in COVID-19 patients. Further inquiry is necessary to determine the optimal timing and identification of patient risk factors predictive of improved survival in COVID-19 patients undergoing tracheotomy.

Long-term Outcomes of Juvenile Onset Recurrent Respiratory Papillomatosis with Pulmonary Involvement.

OBJECTIVE: To investigate the clinical characteristics and long-term outcomes of juvenile onset recurrent respiratory papillomatosis (JORRP) with or without pulmonary involvement. METHODS: A group of patients with JORRP who had clinical course over an extended period of time (at least 5 years) in the Department of Otolaryngology Head and Neck Surgery, Beijing Tongren Hospital were included in this retrospective study. Lung/bronchus involvement was revealed by lung imaging. Data on mortality rate, frequency of surgical interventions, and age of disease onset were collected and analyzed. RESULTS: The 192 patients (107 male and 85 female) included had a median [quartiles] age of JORRP onset of 2 [1, 4] years, and median follow-up duration of 10 [7, 13] years; 17 patients (8.9%) had papilloma with bronchial and pulmonary involvement 7.0 [4.0, 12.5] years after the onset of the disease. Compared to patients without lung involvement, patients with lung involvement had a younger age of disease onset (P = .001), higher frequency of surgical interventions (P < .001), higher mortality rate (OR = 94.909), and an increased risk of tracheotomy that could not be decannulated (P < .001). They also had a younger age of disease onset, and a higher frequency of surgical interventions and mortality compared to patients with tracheotomy but free from lung involvement (P < .001). CONCLUSIONS: Children with JORRP and with pulmonary involvement have a higher average number of operations per year than those without pulmonary involvement, and pulmonary involvement indicates a higher incidence of tracheotomy that cannot be decannulated.

Predictive Nomogram for the Necessity of Tracheotomy During Oral and Oropharyngeal Cancer Surgery.

OBJECTIVES/HYPOTHESIS: The individualized risk of airway obstruction after head and neck cancer surgery is unclear, especially oral and oropharyngeal cancer. The study aimed to establish an individualized predictive model for the necessity of temporary tracheotomy in these patients. METHODS: Patients who underwent oral and oropharyngeal cancer surgery from 1999 to 2019 were retrospectively reviewed. A nomogram was developed and validated in patients treated from 1999 to 2009 and 2010 to 2019, respectively. RESULTS: In total, 1551 patients were included. Oropharyngeal cancer, large tumor, midline crossing, preoperative radiation, mandibulectomy, flap reconstruction, and neck dissection were independent risk factors of postoperative airway obstruction in the training group (n = 707). A nomogram incorporating these factors had a C-index of 0.931 and was validated in the testing group (n = 844) (C-index, 0.918). Good calibration curves were observed in both groups. CONCLUSIONS: The nomogram successfully predicted the individual risk of postoperative airway obstruction for patients with oral and oropharyngeal cancer. LEVEL OF EVIDENCE: 4.

Tracheotomy Timing and Outcomes in the Critically Ill: Complexity and Opportunities for Progress.

OBJECTIVES/HYPOTHESIS: To characterize the effects of tracheotomy timing at our institution on intensive care unit (ICU) length of stay (LOS) and overall hospital LOS. STUDY DESIGN: Retrospective cohort study. METHODS: A retrospective study was performed at a tertiary care medical center for patients undergoing tracheotomy over 2.5 years from January 1, 2016 through June 30, 2018. Demographics, survival, duration of endotracheal intubation, timing of tracheotomy, and ICU and overall hospital LOS were assessed. Tracheotomy was considered early (ET) if it was performed by day 7 of mechanical ventilation and late (LT) thereafter. Readmission, mortality, and costs were also tabulated for each aggregate group. Nonparametric statistics were used to compare results. RESULTS: Of the 536 patients included in the analysis, 160 received tracheotomy early and 376 late. Differences between age and sex were not statistically significant. Duration of total ICU stay was shortened by 65% (12.84 ± 17.69 days vs. 38.49 ± 26.61 days; P < .0001), and length of overall hospital course was reduced by 54% (22.71 ± 26.65 days vs. 50.37 ± 34.20 days; P < .0001) in the early tracheotomy group. Observed/expected (O/E) values standardized results to case mix index and revealed LOS of 1.5 for ET and 2.5 for LT, and mortality of 0.76 for ET and 1.25 for LT, and comparable readmissions of both groups. CONCLUSIONS: Early tracheotomy in ICU patients is associated with earlier ICU discharge, decreased length of overall hospital stay, and lower mortality when controlling for case mix index. Opportunities exist to optimize patient outcomes and O/E performance. LEVEL OF EVIDENCE: 4 Laryngoscope, 131:282-287, 2021.

Low rates of airway intervention in adult supraglottitis: A case series and meta-analysis.

PURPOSE: Acute supraglottitis (SG) can potentially lead to rapid airway obstruction. The last few decades have witnessed a shift towards a more conservative approach in airway management of adult SG. This study aims to evaluate this watchful approach based on a large case series combined with a high-level meta-analysis of all reports in the English literature. METHODS: Retrospective case series and meta-analysis. The medical records of all adult patients diagnosed as having SG who were hospitalized in a large-volume tertiary referral center between January 2007 and December 2018 were reviewed. A meta-analysis was conducted on all English literature published between 1990 and 2018. RESULTS: A total of 233 patients (median age 49.1 years, 132 males), were admitted due to acute SG during the study period. No airway intervention was required in 228 patients (97.9%). Five patients (2.1%) required preventive intubation, and two of them (0.9%) were later surgically converted to a tracheotomy. Patients who required airway intervention had higher rates of diabetes (P = .001), cardiovascular diseases (P = .036) and other comorbidities (P = .022). There was no mortality. The meta-analysis revealed that the overall intubation rates random effects model was 8.8% [95% confidence interval (CI) 4.6%-14.0%] and that the tracheotomy random effects model was 2.2% (95% CI; 0.5%-4.8%). The overall mortality rate was 0.89%. CONCLUSIONS: This study provides evidence of low rates of surgical airway intervention in patients diagnosed with SG worldwide. A conservative approach in adult SG is safe and should be advocated. LEVEL OF EVIDENCE: 2.

Long-term functional prognosis of patients with aneurysmal subarachnoid hemorrhage treated with rehabilitation combined with hyperbaric oxygen: Case-series study.

The long-term prognosis of patients with aneurysmal subarachnoid hemorrhage (aSAH) has received increasing attention in recent years. Hyperbaric oxygen and rehabilitation are already used in clinical treatment of patients with aSAH, but it is unclear whether it can improve the long-term prognosis of patients postoperation. The purpose of this study was to evaluate the long-term prognosis and prognostic factors associated with combined rehabilitation and hyperbaric oxygen therapy for patients with aSAH.Information were retrospectively collected from patients with aSAH treated from October 2014 to July 2017, including demographics, history of hypertension, Hunt-Hess Grade at the time of onset, location of aneurysm, surgical treatment, status of delayed cerebral ischemia and tracheotomy, level of consciousness impairment (Glasgow Coma scale [GCS], neurologic function damage (National Institutes of Health Stroke Scale [NIHSS]), status of hydrocephalus, time of initial hyperbaric oxygen and rehabilitation therapy, as well as duration and frequency of hyperbaric oxygen therapy, and so on. Long-term functional prognosis was measured by modified Rankin scale (mRS), and mRS ≤3 was defined as good prognosis. Univariate and multivariate logistic regression were used to analyze predictors associated with poor prognosis.A total of 44 patients with aSAH were enrolled, and 25 patients (56.8%) had a good functional prognosis 6 months after disease onset. Univariate analysis showed age (P = .028), hyperbaric oxygen and rehabilitation start time (P = .039), NIHSS (P = .000), hydrocephalus (P = .024), frequency of hyperbaric oxygen therapy (P = .016), GCS ≤8 points (P = .000), and tracheotomy (P = .007) were associated with prognosis. Multivariate logistic regression analysis showed that only a higher NIHSS score was an independent predictor of poor prognosis (odds ratio = 1.59; 95% confidence interval, 1.10-2.30).More than 50% of patients with aSAH can achieve a good functional prognosis after combined rehabilitation and hyperbaric oxygen therapy. The severity of neurological impairment before treatment is closely related to poor prognosis.

Advanced airway management success rates in a national cohort of emergency medical services agencies.

OBJECTIVE: Despite its important role in care of the critically ill, there have been few large-scale descriptions of the epidemiology of Emergency Medical Services (EMS) advanced airway management (AAM) and the variations in care with different patient subsets. We sought to characterize AAM performance in a national cohort of EMS agencies. METHODS: We used data from ESO Solutions, Inc., a national EMS electronic health record system. We analyzed EMS emergency patient encounters during 2011-2015 with attempted AAM. We categorized AAM techniques as conventional endotracheal intubation (cETI), neuromuscular blockade assisted intubation (NMBA-ETI), supraglottic airway (SGA), and cricothyroidotomy (needle and open). Determination of successful AAM was based on EMS provider report. We analyzed the data using descriptive statistics, determining the incidence and clinical characteristics of AAM cases. We determined success rates for each AAM technique, stratifying by the subsets cardiac arrest, medical non-arrest, trauma, and pediatrics (age ≤12 years). RESULTS: AAM occurred in 57,209 patients. Overall AAM success was 89.1% (95% CI: 88.8-89.3%) across all patients and techniques. Intubation success rates varied by technique; cETI (n = 38,004; 76.9%, 95% CI: 76.5-77.3%), NMBA-ETI (n = 6768; 89.7%, 88.9-90.4%). SGAs were used both for initial (n = 9461, 90.1% success, 95% CI: 89.5-90.7%) and rescue (n = 5994, 87.3% success, 95% CI: 86.4-88.1%) AAM. Cricothyroidotomy success rates were low: initial cricothyroidotomy (n = 202, 17.3% success, 95% CI: 12.4-23.3%), rescue cricothyroidotomy (n = 85, 52.9% success, 95% CI: 41.8-88%). AAM success rates varied by patient subset: cardiac arrest (n = 35,782; 91.7%, 95% CI: 91.4-92.0), medical non-arrest (n = 17,086; 84.7%, 84.2-85.2%); trauma (n = 4341; 84.3%, 83.1-85.3%); pediatric (n = 1223; 73.7%, 71.2-76.2%). CONCLUSION: AAM success rates varied by airway technique and patient subset. In this national cohort, these results offer perspectives of EMS AAM practices.

[Tracheotomy in children with neuromuscular diseases and regular schooling: are they compatible?] / Trachéotomie chez les enfants atteints de maladies neuromusculaires et scolarisation en milieu ordinaire - Sont-elles compatibles ?

Ventilating a young patient via a tracheostomy remains an invasive method to tackle the respiratory compromise often observed in several neuromuscular disorders. This approach significantly impacts the schooling of these children. The authors have surveyed professionals dealing with education, care, or social support nationwide. Regional discrepancies in practices of schooling in such situations are noted. Tracheostomy seems a major factor of exclusion out of the ordinary schooling system.

ABSTRACT: Les enfants atteints de maladies neuromusculaires nécessitent parfois une assistance ventilatoire au long cours. Parmi les techniques employées, la ventilation sur trachéotomie reste par définition invasive et à même de mettre en péril l'intégration scolaire du jeune malade.

Management of combined massive burn and blast injury: A 20-year experience.

INTRODUCTION: Blast injuries are complex types of physical trauma resulting from direct or indirect exposure to an explosion, which can be divided into four classes: primary, secondary, tertiary, and quaternary. Primary blast injury results in damage, principally, in gas-containing organs such as the lungs (blast lung injury, BLI). BLI is defined as radiological and clinical evidence of acute lung injury occurring within 12h of exposure to an explosion and not due to secondary or tertiary injury. BLI often combines with cutaneous thermal injury, a type of quaternary blast injury, either in terrorist bomb attacks or in civilian accidental explosions. This report summarizes our experience in the management of combined massive burn and BLI at a Shanghai Burn Center in China. METHODS: A retrospective observational analysis of clinical data was performed for massive burn patients with or without BLI during a 20-year interval. Patient characteristics, causes of injury, clinical parameters, management, and outcomes were recorded and evaluated. RESULTS: A total of 151 patients (120 males and 31 females) with severe burn injury (≥50% TBSA) treated at the Burn Center of Changhai Hospital in Shanghai between July 1997 and June 2017 were enrolled in this study. Their mean age was 38.6±17.8 (3-75) years. Among them, 28 patients had combined BLI and burn injury and 39 patients had no BLI or smoke inhalation injury (non-BLI-SII). No significant difference was observed in the burn area or full-thickness burn area between the two groups. The lowest PaO2/fraction of inspired oxygen (FiO2) ratio during the first 24h in BLI patients was significantly lower than that in non-BLI-SII patients. Exudative changes were observed by X-ray radiography in all BLI patients but not in non-BLI-SII patients within 6h after injury. A significantly higher proportion of colloids were used for fluid resuscitation in BLI patients than that in non-BLI-SII patients. A higher proportion and longer time of mechanical ventilation were needed for BLI patients than those for non-BLI-SII patients, and a higher proportion of patients received sedative agents in the BLI group than those in the non-BLI-SII group. The first escharectomy was performed relatively later in BLI patients than in non-BLI-SII patients because of more time taken by BLI patients to recover from lung injury. The length of ICU and hospital stay in BLI patients was significantly longer than that in non-BLI-SII patients. No significant difference in the overall mortality was detected between these two groups. CONCLUSION: It is a formidable challenge for clinicians to diagnose and manage massive burn patients combined with BLI. A comprehensive treatment approach is strongly recommended, including fluid resuscitation, airway management, mechanical ventilation, and surgical treatment. Given the high mortality of massive burn patients combined with BLI even in a recognized burn center, more prospective studies are encouraged to assess more effective strategies for the treatment of such patients.

National questionnaire on skills and techniques in pediatric tracheotomy surgery in Turkey.

OBJECTIVE: The aim of the study was to determine the differences in surgical preferences of ENT Surgeons in Turkey with regard to pediatric tracheotomy. DESIGN: Questionnaire study. PARTICIPANTS: ENT Surgeons. MATERIALS AND METHODS: The national multiple-choice questionnaire study included a total of 16 questions about physicians technical preferences, different methods and complications in pediatric tracheotomy surgery. It was planned and implemented with the support of a professional survey company (www.surveymonkey.com). RESULTS: The questionnaire was answered by 591 ENT Surgeons; the percentage of the physicians performing pediatric tracheotomies in the previous year was 59.6%. Forty point four percent (40.4%) of the physicians had not performed tracheotomies in the pediatric age group and 57.9% had not performed tracheotomies in patients under one year old. Seventy point six percent (70.6%) of the physicians who had performed tracheotomies had made vertical skin incisions, 69.5% of them had removed subcutaneous adipose tissue, 81.4% of them had retraction the thyroid isthmus area from their field of view; 83.9% of them had made a vertical incision to the trachea, 82.5% of them had applied a stay suture to the trachea and 4.7% of them had used additional techniques for stoma maturation. The intraoperative mortality, early complication, late complication, and total complication rates were 3.9%, 32.7%, 21.2% and 53.9 respectively. CONCLUSIONS: This is the first large-scale questionnaire study with data on pediatric tracheotomy techniques and the practices of ENT Surgeons at a national level. Common approaches were observed among the.

Manejo anestésico de la cirugía de implante de marcapasos diafragmático. Experiencia en el Institut Guttmann / Anesthetic management of the diaphragmatic pacemaker placement surgery. Our experience in the Institut Guttmann

INTRODUCCIÓN: El marcapasos diafragmático (MD) ha demostrado su utilidad en la sustitución de la ventilación mecánica en pacientes afectos de lesiones medulares crónicas (LMC) y esclerosis lateral amiotrófica (ELA), mejorando la calidad de vida y reduciendo la morbimortalidad y los costes sanitarios asociados. El manejo anestésico de dichos pacientes y las particularidades del procedimiento quirúrgico suponen un reto anestésico. El objetivo de nuestro estudio es el análisis del manejo y las complicaciones intraoperatorias de los pacientes sometidos a MD en nuestra institución. METODOLOGÍA: Se trata de una revisión retrospectiva entre diciembre de 2007 y julio de 2018. Se recogieron datos sobre el estado previo del paciente, el manejo anestésico y las complicaciones intraoperatorias. RESULTADOS: Se incluyen 16 pacientes (5 pediátricos) con indicación de MD por LMC (63%), ELA (25%) y otras enfermedades neurológicas (12%). Se requirió anestesia general para la laparoscopia abdominal utilizando inducción intravenosa (87%) o inhalatoria (13%) y anestesia total intravenosa (50%) o balanceada (50%) para el mantenimiento anestésico. En un caso se administró rocuronio para un óptimo manejo de la vía aérea. Las complicaciones registradas incluyeron: hipotensión arterial (50%), dificultades en la ventilación mecánica durante la laparoscopia (31%), pneumotárax (12,5%) y disreflexia autonómica (6%). CONCLUSIONES: La colocación de MD bajo anestesia general es una intervención segura, tanto en el paciente adulto como en el pediátrico, en la que pueden aparecer complicaciones derivadas tanto de la enfermedad de base como de la técnica quirúrgica, siendo necesaria una rápida identificación y tratamiento de las mismas para el buen desarrollo del procedimiento

BACKGROUND: The diaphragm pacemaker (DP) has proven its utility in replacing mechanical ventilation in patients with chronic spinal cord injury (SCI) and amyotrophic lateral sclerosis (ALS). The DP improves patient quality of life and reduces morbidity and mortality and their associated health care costs. The anesthetic management of these patients and the particularities of the surgical procedure are challenging. The aim of our study is to analyze anesthetic management and intraoperative complications in patients undergoing DP placement in our hospital. METHODS: We performed a chart review of patients treated between December 2007 and July 2017, recording the patients' preoperative status, anesthetic management and intraoperative complications. RESULTS: The study included 16 patients (5 pediatric) undergoing DP implantation for chronic SCI (63%), ALS (25%) and other neurologic conditions (12%). Abdominal laparoscopy was performed under general anesthesia, with intravenous (87%) or inhalational (13%) induction and maintenance using total intravenous (50%) or balanced (50%) anesthesia. Rocuronium was administered in one case to permit airway management. Complications included: hypotension (50%), difficulties in mechanical ventilation during laparoscopy (31%), pneumothorax (12.5%) and autonomic dysreflexia (6%). CONCLUSIONS: DP placement under general anesthesia is a safe intervention in both adult and pediatric patients. Complications derived from both the underlying disease and the surgical technique may appear, and must be rapidly identified and treated to obtain a satisfactory surgical outcome

Predictors of mortality and validation of burn mortality prognostic scores in a Malaysian burns intensive care unit.

BACKGROUND: Majority burn mortality prognostic scores were developed and validated in western populations. The primary objective of this study was to evaluate and identify possible risk factors which may be used to predict burns mortality in a local Malaysian burns intensive care unit. The secondary objective was to validate the five well known burn prognostic scores (Baux score, Abbreviated Burn Severity Index (ABSI) score, Ryan score, Belgium Outcome Burn Injury (BOBI) score and revised Baux score) to predict burn mortality prediction. METHODS: Patients that were treated at the Hospital Sultan Ismail's Burns Intensive Care (BICU) unit for acute burn injuries between 1 January 2010 to 31 December 2017 were included. Risk factors to predict in-patient burn mortality were gender, age, mechanism of injury, total body surface area burn (TBSA), inhalational injury, mechanical ventilation, presence of tracheotomy, time from of burn injury to BICU admission and initial centre of first emergency treatment was administered. These variables were analysed using univariate and multivariate analysis for the outcomes of death. All patients were scored retrospectively using the five-burn mortality prognostic scores. Predictive ability for burn mortality was analysed using the area under receiver operating curve (AUROC). RESULTS: A total of 525 patients (372 males and 153 females) with mean age of 34.5 ± 14.6 years were included. There were 463 survivors and 62 deaths (11.8% mortality rate). The outcome of the primary objective showed that amongst the burn mortality risk factors that remained after multivariate analysis were older age (p = 0.004), wider TBSA burn (p < 0.001) and presence of mechanical ventilation (p < 0.001). Outcome of secondary objective showed good AUROC value for the prediction of burn death for all five burn prediction scores (Baux score; AUROC:0.9, ABSI score; AUROC:0.92, Ryan score; AUROC:0.87, BOBI score; AUROC:0.91 and revised Baux score; AUROC:0.94). The revised Baux score had the best AUROC value of 0.94 to predict burns mortality. CONCLUSION: Current study evaluated and identified older age, total body surface area burns, and mechanical ventilation as significant predictors of burn mortality. In addition, the revised Baux score was the most accurate burn mortality risk score to predict mortality in a Malaysian burn's population.

Laryngo-tracheal resections in the Nordic countries: an option for further centralization?

PURPOSE: We aimed to obtain information on the number of Nordic centers performing tracheal resections, crico-tracheal resections, and laryngo-tracheal reconstructions, as well as the patient volume and the standard regimens associated with these procedures. METHODS: Consultants at all Departments of Otorhinolaryngology-Head and Neck Surgery (ORL-HNS, n = 22) and Thoracic Surgery (n = 21) in the five Nordic countries were invited (April 2018-January 2019) to participate in an online survey. RESULTS: All 43 departments responded to the survey. Twenty departments declared to perform one or more of the three types of tracheal resections. At five hospitals, departments of ORL-HNS and Thoracic Surgery perform these operations in collaboration. Hence, one or more of the tracheal operations in question are carried out at 15 centers. The median annual number of tracheal operations per center is five (range 1-20). Great variations were found regarding contraindications (relative and absolute) for surgery, the use of guardian sterno-mental sutures (all patients, 33%; selected cases, 40% of centers), prophylactic antibiotic therapy (cefuroxime +/- metronidazole, penicillin +/- metronidazole, clindamycin, imipenem, or none), post-operative follow-up time (range: children: 3-120 months; adults: 0-60 months), and the performance of post-operative bronchoscopy. CONCLUSIONS: Fifteen centers each perform a low number of annual operations with significant variations in the selection of patients and the clinical setup, which raises the question if a higher degree of collaboration and centralization would be warranted. We encourage Nordic transnational collaboration, pursuing alignment on central management issues, and establishment of a common prospective database for future tracheal resection surgery.

Otorhinolaryngology surgery analysis in Japan and Thailand: Comparing Nihon University School of Medicine with Thammasat University Faculty of Medicine.

BACKGROUND/OBJECTIVE: We compared the surgery data of the department of otorhinolaryngology of the university hospitals in Japan and Thailand to make each feature and the differences of both otorhinolaryngology surgeries clear. There are some medical meetings and congresses between Japan and Thailand, but so far it has not reported about the comparison of surgery data. METHODS: Retrospectively, we analyzed the surgical statistics of department of otorhinolaryngology of Nihon University Itabashi Hospital (Japan) and Thammasat University Hospital (Thailand) between 2013 and 2014. RESULTS: In Japan, there were many surgeries involving the middle ear and paranasal sinuses whereas in Thailand, tracheotomy and tonsillectomy were more frequently performed. Statistical analysis of the surgical data revealed specific tendencies in the nature of the operations performed at each university. CONCLUSION: This study revealed that there are rather differences between two hospitals' surgeries features. It was thought that it would be beneficial to both institutions to gain a deeper understanding of the areas of expertise of each university in order to foster an environment conducive to increasing future international collaborations.
