RESUMEN
OBJECTIVE: Report long-term tracheostomy outcomes in patients with COVID-19. STUDY DESIGN: Review of prospectively collected data. METHODS: Prospectively collected data were extracted for adults with COVID-19 undergoing percutaneous or open tracheostomy between April 4, 2020 and June 2, 2020 at a major medical center in New York City. The primary endpoint was weaning from mechanical ventilation. Secondary outcomes included sedation weaning, decannulation, and discharge. RESULTS: One hundred one patients underwent tracheostomy, including 48 percutaneous (48%) and 53 open (52%), after a median intubation time of 24 days (IQR 20, 31). The most common complication was minor bleeding (n = 18, 18%). The all-cause mortality rate was 15% and no deaths were attributable to the tracheostomy. Eighty-three patients (82%) were weaned off mechanical ventilation, 88 patients (87%) were weaned off sedation, and 72 patients (71%) were decannulated. Censored median times from tracheostomy to sedation and ventilator weaning were 8 (95% CI 6-11) and 18 (95% CI 14-22) days, respectively (uncensored: 7 and 15 days). Median time from tracheostomy to decannulation was 36 (95% CI 32-47) days (uncensored: 32 days). Of those decannulated, 82% were decannulated during their index admission. There were no differences in outcomes or complication rates between percutaneous and open tracheostomy. Likelihood of discharge from the ICU was inversely related to intubation time, though the clinical relevance of this was small (HR 0.97, 95% CI 0.943-0.998; P = .037). CONCLUSION: Tracheostomy by either percutaneous or open technique facilitated sedation and ventilator weaning in patients with COVID-19 after prolonged intubation. Additional study on the optimal timing of tracheostomy in patients with COVID-19 is warranted. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E2849-E2856, 2021.

Extubation failure (EF) following neonatal cardiac surgery is associated with increased mortality. Neonates who experienced EF twice or more (recurrent EF) may have worse outcomes than those who have a single EF or no-EF. The aims of this study are to investigate the in hospital mortality for neonates with recurrent EF compared to those with single or no-EF, and determine factors associated with recurrent EF. Neonates' ≤ 28 days who underwent cardiac surgery from January 2008 to December 2019 were included. EF was defined as unplanned reintubation within 72 h after a planned extubation. 1187 (18 recurrent EF, 84 single EF and 1085 no-EF) neonates were included. Recurrent EF occurred in 18 (17.6%) of 102 neonates undergoing a second extubation. The median time (IQR) to reintubation after the first and second extubations were similar, being 20.9 (3.3-45.2) versus 19.4 (5.5-47) h. The reason for a second-time EF was respiratory in 39% and cardiovascular in 33%. Recurrent EF and single EF was associated with increased mortality (odds ratio, 95% confidence interval (CI) 23.5, 6.9-79.9) and (odds ratio, 95% CI 5.2, 2.3-12.0) compared to no-EF. Based on the final model with risk adjustment, predicted mortality was 29.0% in recurrent EF, 6.5% in single EF, and 1.2% in no-EF. First-time EF due to cardiovascular compromise was associated with recurrent EF (odds ratio, 95% CI 3.1, 1.0-9.7). This study confirmed that patients with recurrent EF have a high morality. Neonates with a cardiovascular reason for first-time EF are more likely to have a recurrent EF than those with other causes.

BACKGROUND: Operating room (OR) extubation has been reported after lung transplantation (LT) in small cohorts. This study aimed to evaluate the prognosis of OR-extubated patients. The secondary objectives were to evaluate the safety of this approach and to identify its predictive factors. METHODS: This retrospective single-center cohort study included patients undergoing double lung transplantation (DLT) from January 2012 to June 2019. Patients undergoing multiorgan transplantation, repeat transplantation, or cardiopulmonary bypass during the study period were excluded. OR-extubated patients were compared with intensive care unit (ICU)-extubated patients. RESULTS: Among the 450 patients included in the analysis, 161 (35.8%) were extubated in the OR, and 4 were reintubated within 24 hours. Predictive factors for OR extubation were chronic obstructive pulmonary disease (COPD)/emphysema (pâ¯=â¯.002) and cystic fibrosis (pâ¯=â¯.005), recipient body mass index (pâ¯=â¯.048), and the PaO2/FiO2 ratio 10 minutes after second graft implantation (p < .001). OR-extubated patients had a lower prevalence of grade 3 primary graft dysfunction at day 3 (p < .001). Eight (5.0%) patients died within the first year after OR extubation, and 49 (13.5%) patients died after ICU extubation (log-rank test; pâ¯=â¯.005). After adjustment for OR extubation predictive factors, the multivariate Cox regression model showed that OR extubation was associated with greater one-year survival (adjusted hazard ratioâ¯=â¯0.40 [0.16-0.91], pâ¯=â¯.028). CONCLUSIONS: OR extubation was associated with a favorable prognosis after DLT, but the association should not be interpreted as causality. This fast-track protocol was made possible by a team committed to developing a comprehensive strategy to enhance recovery.

OBJECTIVES: To compare the safety and resource-efficacy of the fast-track (FT) concept (extubation ≤8 hours after surgery) versus the conventional approach (non-FT, >8 hours postoperatively) in infants undergoing open-heart surgery. METHODS: Infants <7 kg operated on cardiopulmonary bypass between 2014 and 2018 were analyzed. Propensity score matching (1:1) was performed for group comparison (FT vs non-FT). Intensive care unit (ICU) personnel use and unit performance were evaluated. Postoperative outcome and reimbursement based on German diagnosis-related groups were compared. RESULTS: Of 717 infants (median age: 4 months, Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery mortality score: 0.1-4), FT extubation was achieved in 182 infants (25%). After matching, 123 pairs (FT vs non-FT) were formed without significant differences in baseline characteristics. FT versus non-FT showed a significantly shorter ICU stay (in days): 1.8 (0.9-2.8) versus 4.2 (1.9-6.4), P < .01, and postoperative length of stay (in days): 7 (6-10) versus 10 (7-15.5), P < .01; significantly lower postoperative transfusion rates: 61.3% versus 77%, P < .01; and tendency toward lower early mortality: 0% versus 2.8%, P = .08. Reintubation rate did not differ between the groups (P = .7). Despite a decrease in personnel capacity (2014 vs 2018), the unit performance was maintained. The mean case-mix-index of FT versus non-FT was 8.56 ± 6.08 versus 11.77 ± 12.10 (P < .01), resulting in 27% less reimbursement in the FT group. CONCLUSIONS: FT concept can be performed safely and resource-effectively in infants undergoing open-heart surgery. Since German diagnosis-related group systems reimburse costs, not performance, there is little incentive to avoid prolonged mechanical ventilation. Greater ICU turnover rates and excellent postoperative outcomes are not rewarded adequately.

The main objective of this study was to evaluate the outcomes of extremely elderly patients receiving orotracheal intubation and mechanical ventilation after planned extubation. This retrospective cohort study included extremely elderly patients (>90 years) who received mechanical ventilation and passed planned extubation. We reviewed all intensive care unit patients in a medical center between January 1, 2010, and December 31, 2017. There were 19,518 patients (aged between 20 and 105 years) during the study period. After application of the exclusion criteria, there were 213 patients who underwent planned extubation: 166 patients survived, and 47 patients died. Compared with the mortality group, the survival group had lower Acute Physiology and Chronic Health Evaluation II scores and higher Glasgow Coma Scale (GCS) scores, with scores of 19.7â±â6.5 (meanâ±âstandard deviation) vs 22.2â±â6.0 (Pâ=â.015) and 9.5â±â3.5 vs 8.0â±â3.0 (Pâ=â.007), respectively. The laboratory data revealed no significant difference between the survival and mortality groups except for blood urea nitrogen (BUN) and hemoglobin. After multivariate logistic regression analysis, a lower GCS, a higher BUN level, weaning beginning 3 days after intubation and reintubation during hospitalization were associated with poor prognosis. In this cohort of extremely elderly patients undergoing planned extubation, a lower GCS, a higher BUN level, weaning beginning 3 days after intubation and reintubation during hospitalization were associated with mortality.

Introducción: la discontinuación de la ventilación mecánica invasiva en las Unidades de Cuidados Intensivos es un objetivo fundamental y primario, en pos de evitar las complicaciones asociadas a ella. El uso de ventilación no invasiva en este contexto resulta de utilidad en tres escenarios específicos: a) como prevención de fallo de extubación, b) como cambio de interface, c) en fallo instalado. No existe evidencia suficiente sobre el tiempo de uso habitual de la VNI en esta subpoblación, las variables que se utilizan para elegirla, las causas de fallo de la VNI y la mortalidad asociada en estos pacientes. Objetivos: describir epidemiológicamente a los pacientes adultos con uso de VNI posextubación y su evolución hasta el alta hospitalaria. Describir la indicación de VNI, el tiempo de uso, las tasas de reintubación y mortalidad intrahospitalaria. Materiales y métodos: cohorte retrospectiva de pacientes internados en la UCI de adultos del Hospital Italiano de San Justo que utilizaron VNI posextubación. A partir de la historia clínica electrónica se registraron variables epidemiológicas previas al ingreso en la UCI y datos evolutivos durante la internación. El período analizado abarca desde el 17 de diciembre de 2016 hasta el 01 de agosto de 2018. Resultados: se incluyeron 48 pacientes en el presente estudio. La mediana de edad fue de 76 años (RIQ 62,75-83,25). El 58,33% eran hombres. El índice de comorbilidad de Charlson tuvo un valor de mediana de 5 (RIQ 3-6). Del total de pacientes reclutados, 33 utilizaron VNI como prevención de fallo de extubación (68,75%), 13 como cambio de interface (27,08%) y solo 2 como fallo instalado (4,16%). La mediana de días de uso de VNI fue 1 (RIQ 0-5) en prevención de fallo, 1 (RIQ 1-2) en cambio de interface y en fallo instalado 13,5 días (RIQ 8,75-18,25). Ocho pacientes fueron reintubados (16,66%). La mortalidad fue del 9,1% en el grupo de prevención de fallo y 7,7% en el grupo de cambio de interface, respectivamente. En cuanto al grupo que la usó a partir del fallo instalado, la tasa de mortalidad fue del 50% (total de dos pacientes). Conclusiones: la VNI como método de discontinuación de la VMI se utiliza principalmente tanto para la prevención de fallo como para cambio de interfaz. El tiempo de uso de VNI posextubación es, en general, limitado. Se necesitan futuros trabajos que identifiquen las horas requeridas de uso de VNI posextubación. (AU)
Introduction: the discontinuation of invasive mechanical ventilation in the intensive care unit is a fundamental and primary objective, both of which aim to avoid the complications associated with it. The use of non-invasive ventilation in this context may follow three specific scenarios: a) as prevention of extubation failure, b) as interface change, c) in overt failure. There is not enough evidence on the time of use of NIV in this subpopulation, the variables used to guide its use, the causes of NIV failure and the associated mortality in these patients. Objectives: to describe the use of NIV after extubation in adult critically ill patients. Further, we aim to describe the time of NIV use, the mortality and reintubation rate of each subgroup. Materials and methods: retrospective cohort study including adult patients admitted to the ICU at Hospital Italiano de San Justo, who received NIV post-extubation. Using the electronic health database, epidemiological variables were recorded prior to admission to the ICU and follow-up data during the hospitalization. The period analyzed was from December 17, 2016 to August 1, 2018. Results: 48 patients were included in the present analysis. Median age was 76 years (RIQ 62.75-83.25) and 58.33% were men. The Charlson comorbidity index had a median value of 5 (RIQ 3-6). Of the total number of patients recruited, 33 used NIV as prevention of extubation failure (68.75%), 13 as interface change (27.08%). ) and only 2 as overt extubation failure (4.16%).The median number of days of NIV use was 1 (RIQ 0-5) in failure prevention and 1 (RIQ 1-2) in the change of interface group. 8 patients were reintubated (16.66%). 9.1% and 7.7% of patients died in the groups that used NIV as prevention of extubation failure and change of interface respectively. Conclusions: NIV is frequently used in adult patients following extubation in our centre. Further studies are warranted to depict the necessary time of use to better allocate resources within the intensive care unit. (AU)

BACKGROUND & AIMS: Elderly patients are being increasingly admitted to the intensive care unit (ICU) for mechanical ventilation (MV) and prevalence of decreased skeletal muscle mass which develop with aging is subsequently increasing. The objective of this study was to identify the association between decreased skeletal muscle mass and extubation failure in patients undergoing long-term MV. METHODS: Adults (≥18 years of age) with long-term MV for > 7 days between January 2014 and February 2019 were included retrospectively. Patients who died or were transferred with MV, underwent tracheostomy with failure of weaning from MV, and had not undergone abdominal computed tomography within 3 days before or after intubation were excluded. Failed extubation was defined as reintubation within 48 h after extubation following long-term MV for >7 days. We divided the patients into extubation success and failure groups. RESULTS: Parameters including patients' demographics, cause of intubation, initial setting of MV, maximum inspiratory pressure (MIP) and rapid shallow breath index (RSBI) at extubation, and skeletal muscle mass were compared between the two groups. Decreased skeletal muscle mass was set a standard as a L3 muscle index of less than 49 cm2/m2 for men and of less than 31 cm2/m2 for women using Korean-specific cut-offs for sarcopenia as evaluated on previous epidemiologic study. Among 104 patients who were screened, 45 were included, and 11 (24.4%) failed to be extubated. Mean MIP (23.5 ± 11.8 vs. 32.4 ± 9.3, p = 0.134) and RSBI (57.2 ± 26.5 vs. 55.3 ± 20.4, p = 0.803) were not different between the two groups. The proportions of patients whose MIP or RSBI satisfied the cutoff for extubation were not different between the groups. There were no significant differences in age, sex, body mass index, comorbidities, nutritional status, and cause of intubation between the two groups. The extubation failure group showed a higher proportion of decreased skeletal muscle mass (90.9% vs. 58.8%, p = 0.05) and longer duration of MV (10.7 ± 4.1 vs. 9.6 ± 3.4, p < 0.001) than the extubation success group. Multivariate analysis showed that the duration of intubation (OR = 1.439, 95% CI = 1.12-1.85), and decreased skeletal muscle mass (OR = 24.382, 95% CI = 1.00-594.86) were associated with extubation failure. CONCLUSIONS: Decreased skeletal muscle mass was associated with extubation failure after long-term MV for > 7 days. It is important to diagnose decreased skeletal muscle mass in critically ill patients to reduce extubation failure rates.

Background: Prophylactic noninvasive ventilation (NIV) after scheduled extubation can benefit patients with chronic respiratory disorders, among which chronic obstructive pulmonary disease (COPD) is a significant example. However, it is not known whether all COPD patients benefit from prophylactic NIV. Methods: We performed a post hoc analysis of prospectively collected data. COPD patients who successfully completed a spontaneous breathing trial were enrolled. In the prophylactic NIV group, NIV was applied immediately after extubation. In the usual care group, conventional oxygen therapy was used. Patients were followed up to 90 days post-extubation. Results: Among patients with PaCO2 > 45 mmHg, 128 and 40 received prophylactic NIV and usual care, respectively. Prophylactic NIV led to lower rates of re-intubation (4% vs 30% at 72 h and 11% vs 35% at 7 days, both p < 0.01) and hospital mortality (18% vs 40%, p < 0.01) than usual care. The proportion of 90-day mortality was also lower in the prophylactic NIV group (log rank test, p = 0.04). Among patients with PaCO2 ≤ 45 mmHg, 32 and 21 received prophylactic NIV and usual care, respectively. In this cohort however, prophylactic NIV neither reduced re-intubation (6% vs 5% at 72 h, p > 0.99, and 9% vs 14% at 7 days, p = 0.67) nor hospital mortality (19% vs 24%, p = 0.74). The proportion of 90-day mortality did not differ between the two groups (log rank test, p = 0.79). Conclusion: This exploratory study shows that prophylactic NIV benefits COPD patients with PaCO2 > 45 mmHg, but it may not benefit those with PaCO2 ≤ 45 mmHg. Further study with a larger sample size is required to confirm this.

OBJECTIVES: Right ventricular pressure overload, which can result in restrictive right ventricular physiology, predicts slow recovery after biventricular repair of congenital heart defects. The goal of the study was to assess how extubation in the operating room influences the postoperative course in these patients. METHODS: Between January 2013 and June 2017, a total of 65 children [median age 0.96 (0.13-9.47) years; median weight 8 (3.05-25.8) kg] with right ventricular pressure overload underwent an intracardiac correction. The most common malformations were tetralogy of Fallot (n = 34) and double outlet right ventricle with pulmonary stenosis (n = 11). The patients were divided into 2 groups: the first (n = 36) comprised late extubated (LE) and the second (n = 29), early extubated (EE) children, immediately after chest closure in the operating room. Preoperative, perioperative and postoperative records were analysed retrospectively. RESULTS: Children who had EE had a lower heart rate (EE 124.2 vs LE 133.6 bpm; P = 0.03), higher arterial blood pressure (systolic: EE 87.9 ± 9.35 vs LE 81.4 ± 12.0 mmHg; P = 0.029; diastolic: EE 51.1 ± 6.5 vs LE 45.9 ± 6.64 mmHg; P = 0.003), lower central venous pressure (EE 8.6 ± 1.89 mmHg vs LE 9.9 ± 2.42 mmHg; P = 0.03), fewer pleural effusions in the first 6 postoperative days (EE 1.38 ml/kg/day vs LE 5.98 ml/kg/day; P = 0.009), shorter time of dopamine support ≥3 µg/kg (EE 7.29 ± 12.26 h vs LE 34.78 ± 38.05 h, P < 0.001), shorter stays in the intensive care unit (EE 2.7 ± 2.67 vs LE 5.0 ± 4.77 days, P = 0.001) and hospital (EE 11.8 ± 4.79 vs LE 15.5 ± 7.8 days; P = 0.022). CONCLUSIONS: Extubation in the operating room of children with right ventricular pressure overload undergoing biventricular correction is feasible and safe and has a beneficial effect on the postoperative course.

BACKGROUND: Diaphragmatic dysfunction may promote weaning difficulties in patients who are mechanically ventilated. OBJECTIVE: The goal of this study was to assess whether diaphragm dysfunction detected by ultrasound prior to extubation could predict extubation failure in the ICU. METHODS: This multicenter prospective study included patients at high risk of reintubation: those aged > 65 years, with underlying cardiac or respiratory disease, or intubated > 7 days. All patients had successfully undergone a spontaneous breathing trial. Diaphragmatic function was assessed by ultrasound prior to extubation while breathing spontaneously on a T-piece. Bilateral diaphragmatic excursion and apposition thickening fraction were measured, and diaphragmatic dysfunction was defined as excursion < 10 mm or thickening < 30%. Cough strength was clinically assessed by physiotherapists. Extubation failure was defined as reintubation or death within the 7 days following extubation. RESULTS: Over a 20-month period, 191 at-risk patients were studied. Among them, 33 (17%) were considered extubation failures. The proportion of patients with diaphragmatic dysfunction was similar between those whose extubation succeeded and those whose extubation failed: 46% vs 51% using excursion (P = .55), and 71% vs 68% using thickening (P = .73), respectively. Values of excursion and thickening did not differ between the success and the failure groups: at right, excursion was 14 ± 7 mm vs 11 ± 8 (P = .13), and thickening was 29 ± 29% vs 38 ± 48% (P = .83), respectively. Extubation failure rates were 7%, 22%, and 46% in patients with effective, moderate, and ineffective cough (P < .01). Ineffective cough was the only variable independently associated with extubation failure. CONCLUSIONS: Diaphragmatic dysfunction assessed by ultrasound was not associated with an increased risk of extubation failure.

BACKGROUND: Failed extubation has been shown to increase ICU stay, transfers to rehabilitation facilities, and mortality. The purpose of this study was to assess the differences in rates of failed extubation before and after implementation of an extubation checklist. METHODS: We performed a retrospective study from January 2013-April 2017 on adult trauma patients (age 18-89) who were admitted to the ICU and required mechanical ventilation. Patients were grouped before and after implementation of an extubation checklist and compared. RESULTS: A total of 993 patients were included in this study. After checklist implementation, significantly fewer patients required reintubation compared to those prior to checklist (7% vs 3%, pâ¯=â¯0.005). There was no difference in mortality (20% vs 21%, pâ¯=â¯0.54) or hospital length of stay between the two groups (16 days vs 15 days, pâ¯=â¯0.16). CONCLUSION: Our study reveals that implementing an extubation checklist is associated with fewer failed extubations.

OBJECTIVE: Immediate extubation may have outcome benefits when judiciously instituted after neonatal congenital cardiac surgery. We sought to evaluate the outcomes of immediate extubation specifically in neonates undergoing stage 1 Norwood palliation of hypoplastic left heart syndrome. METHODS: Consecutive neonates undergoing stage 1 Norwood (January 2010 to December 2016) for hypoplastic left heart syndrome were retrospectively studied. Immediate extubation was defined as successful extubation before termination of anesthetic care. Preoperative and intraoperative variables were compared between immediate extubation and nonimmediate extubation groups, and bivariate analyses and descriptive methods were used to express the association of outcome variables with immediate extubation. Data were expressed as number and percent for categoric variables, and median and interquartile range for continuous variables. RESULTS: Of 23 patients who underwent stage 1 palliation, 5 had immediate extubation (22%). There were no differences in preoperative or intraoperative factors between patients who did and did not undergo immediate extubation. There were no deaths in the immediate extubation group. In the nonimmediate extubation group, 3 patients died before hospital discharge. One patient who had immediate extubation and 4 patients among those who did not have immediate extubation had to be reintubated in the 96 hours that followed extubation (P = 1). Intensive care unit length of stay was 8 (3-17) and 8 (5-18) (days) for the immediate extubation group and nonimmediate extubation groups, respectively (P = .71). CONCLUSIONS: Immediate extubation strategy was safely accomplished in one-fifth of this cohort of hypoplastic left heart syndrome.

OBJECTIVES: Expedient extubation after cardiac surgery has been associated with improved outcomes, leading to postoperative extubation frequently during overnight hours. However, recent evidence in a mixed medical-surgical intensive care unit population demonstrated worse outcomes with overnight extubation. This study investigated the impact of overnight extubation in a statewide, multicenter Society of Thoracic Surgeons database. METHODS: Records from 39,812 patients undergoing coronary artery bypass grafting or valve operations (2008-2016) and extubated within 24 hours were stratified according to extubation time between 06:00 and 18:00 (day) or between 18:00 and 6:00 (overnight). Outcomes including reintubation, mortality, and composite morbidity-mortality were evaluated using hierarchical regression models adjusted for Society of Thoracic Surgeons predictive risk scores. To further analyze extubation during the night, a subanalysis stratified patients into 3 groups: 06:00 to 18:00, 18:00 to 24:00, and 24:00 to 06:00. RESULTS: A total of 20,758 patients were extubated overnight (52.1%) and were slightly older (median age 66 vs 65 years, P < .001) with a longer duration of ventilation (4 vs 7 hours, P < .001). Day and overnight extubation were associated with equivalent operative mortality (1.7% vs 1.7%, P = .880), reintubation (3.7% vs 3.4%, P = .141), and composite morbidity-mortality (8.2% vs 8.0%, P = .314). After risk adjustment, overnight extubation was not associated with any difference in reintubation, mortality, or composite morbidity-mortality. On subanalysis, those extubated between 24:00 and 06:00 exhibited increased composite morbidity-mortality (odds ratio, 1.18; P = .001) but no difference in reintubation or mortality. CONCLUSIONS: Extubation overnight was not associated with increased mortality or reintubation. These results suggest that in the appropriate clinical setting, it is safe to routinely extubate cardiac surgery patients overnight.

Unplanned extubation (UE) can be associated with fatal outcome; however, an accurate model for predicting the mortality of UE patients in intensive care units (ICU) is lacking. Therefore, we aim to compare the performances of various machine learning models and conventional parameters to predict the mortality of UE patients in the ICU. A total of 341 patients with UE in ICUs of Chi-Mei Medical Center between December 2008 and July 2017 were enrolled and their demographic features, clinical manifestations, and outcomes were collected for analysis. Four machine learning models including artificial neural networks, logistic regression models, random forest models, and support vector machines were constructed and their predictive performances were compared with each other and conventional parameters. Of the 341 UE patients included in the study, the ICU mortality rate is 17.6%. The random forest model is determined to be the most suitable model for this dataset with F1 0.860, precision 0.882, and recall 0.850 in the test set, and an area under receiver operating characteristic (ROC) curve of 0.910 (SE: 0.022, 95% CI: 0.867-0.954). The area under ROC curves of the random forest model was significantly greater than that of Acute Physiology and Chronic Health Evaluation (APACHE) II (0.779, 95% CI: 0.716-0.841), Therapeutic Intervention Scoring System (TISS) (0.645, 95% CI: 0.564-0.726), and Glasgow Coma scales (0.577, 95%: CI 0.497-0.657). The results revealed that the random forest model was the best model to predict the mortality of UE patients in ICUs.

BACKGROUND: Extubation failure (ExtF) is associated with prolonged hospital length of stay and mortality in adult cardiac surgery patients postoperatively. In this population, ExtF-related variables such as the arterial partial pressure of oxygen to fraction of inspired oxygen ratio (PaO2/FiO2), rapid shallow breathing index, cough strength, endotracheal secretions and neurological function have been sparsely researched. AIM: To identify variables that are predictive of ExtF and related outcomes. METHOD: Prospective observational longitudinal study. Consecutively presenting patients ( n=205) undergoing open-heart cardiac surgery and admitted to the Cardiosurgical Intensive Care Unit (CICU) were recruited. The clinical data were collected at CICU admission and immediately prior to extubation. ExtF was defined as the need to restart invasive or non-invasive mechanical ventilation while the patient was in the CICU. RESULTS: The ExtF incidence was 13%. ExtF related significantly to hospital mortality, CICU length of stay and total hospital length of stay. The risk of ExtF decreased significantly, by 93% in patients with good neurological function and by 83% in those with a Rapid Shallow Breathing Index of ≥57 breaths/min per litre. Conversely, ExtF risk increased 27 times when the PaO2/FiO2 was <150 and 11 times when it was ≥450. Also, a reassuring PaO2/FiO2 value may hide critical pulmonary or extra-pulmonary conditions independent from alveolar function. CONCLUSION: The decision to extubate patients should be taken after thoroughly discussing and combining the data derived from nursing and medical clinical assessments. Extubation should be delayed until the patient achieves safe respiratory, oxygenation and haemodynamic conditions, and good neurocognitive function.

OBJECTIVES: We introduced an extubation strategy for emphysema patients after bilateral lung transplantation. Patients who met the extubation criteria were extubated in the operating room (OR) followed by non-invasive ventilation, and the other patients were extubated in the intensive care unit (ICU). The primary objective was to determine the extubation rate. The secondary outcomes were to determine the factors allowing for extubation in the OR and the postoperative course. METHODS: This study is a single-centre retrospective database analysis of 96 patients. Anaesthesia was performed using automated titration of total intravenous anaesthesia combined with thoracic epidural analgesia. Extubation criteria included arterial partial pressure oxygen (PaO2)/fraction of inspired oxygen (FiO2) ratio, chest radiograph, oedema and haemodynamic stability. Data were compared using non-parametric tests and expressed as median (interquartile ranges) or number (%). RESULTS: Fifty-three (55%) patients were extubated in the OR (the OR group) with 1 requiring reintubation and 43 (45%) patients were extubated in the ICU (the ICU group). Preoperative pulmonary hypertension, the requirement for intraoperative extracorporeal membrane oxygenation (ECMO), bleeding and ex vivo lung reconditioning donors were lower in the OR group. At the end of the procedure, the PaO2/FiO2 ratio was better [352 (289-437) vs 206 (144-357), P = 0.004), and the need for postoperative ECMO, mechanical ventilation duration, length of stay in the ICU [5 (4-7) vs 12 (8-20) days, P < 0.0001], Grade 3 primary graft dysfunction at 72 h [1 (2%) vs 10 (24%), P = 0.002] and 1-year mortality [5 (9%) vs 11 (26%) patients, P = 0.014] were lower in the OR group than in the ICU group. CONCLUSIONS: Half of patients were extubated in the OR, and this strategy does not require additional ICU resources.

The periextubation period represents a crucial moment in the management of critically ill patients. Extubation failure, defined as the need for reintubation within 2-7 days after a planned extubation, is associated with prolonged mechanical ventilation, increased incidence of ventilator-associated pneumonia, longer intensive care unit and hospital stays, and increased mortality. Conventional oxygen therapy is commonly used after extubation. Additional methods of non-invasive respiratory support, such as non-invasive ventilation and high-flow nasal therapy, can be used to avoid reintubation. The aim of this Review is to describe the pathophysiological mechanisms of postextubation respiratory failure and the available techniques and strategies of respiratory support to avoid reintubation. We summarise and discuss the available evidence supporting the use of these strategies to achieve a tailored therapy for an individual patient at the bedside.

BACKGROUND: Withdrawal of mechanical ventilation is an important, but rarely explored issue in Asia during end-of-life care. This study aimed to describe the clinical characteristics and survival outcomes of terminally ill patients undergoing withdrawal of mechanical ventilation in Taiwan. METHODS: One-hundred-thirty-five terminally ill patients who had mechanical ventilation withdrawn between 2013 and 2016, from a medical center in Taiwan, were enrolled. Patients' clinical characteristics and survival outcomes after withdrawal of mechanical ventilation were analyzed. RESULTS: The three most common diagnoses were organic brain lesion, advanced cancer, and newborn sequelae. The initiator of the withdrawal process was family, medical personnel, and patient him/herself. The median survival time was 45 min (95% confidence interval, 33-57 min) after the withdrawal of mechanical ventilation, and 102 patients (75.6%) died within one day after extubation. The median time from diagnosis of disease to receiving life-sustaining treatment and artificial ventilation support, receiving life-sustaining treatment and artificial ventilation support to "Withdrawal meeting," "Withdrawal meeting" to ventilator withdrawn, and ventilator withdrawn to death was 12.1 months, 19 days, 1 day, and 0 days, respectively. Patients with a diagnosis of advanced cancer and withdrawal initiation by the patients themselves had a significantly shorter time interval between receiving life-sustaining treatment and artificial ventilation support to "Withdrawal meeting" compared to those with non-cancer diseases and withdrawal initiation by family or medical personnel. CONCLUSION: This study is the first observational study to describe the patients' characteristics and elaborate on the survival outcome of withdrawal of mechanical ventilation in patients who are terminally ill in an Asian population. Understanding the clinical characteristics and survival outcomes of mechanical ventilation withdrawal might help medical personnel provide appropriate end-of-life care and help patients/families decide about the withdrawal process earlier.

PURPOSE: The relative merits of immediate extubation versus terminal weaning for mechanical ventilation withdrawal are controversial, particularly regarding the experience of patients and relatives. METHODS: This prospective observational multicentre study (ARREVE) was done in 43 French ICUs to compare terminal weaning and immediate extubation, as chosen by the ICU team. Terminal weaning was a gradual decrease in the amount of ventilatory assistance and immediate extubation was extubation without any previous decrease in ventilatory assistance. The primary outcome was posttraumatic stress symptoms (Impact of Event Scale Revised, IES-R) in relatives 3 months after the death. Secondary outcomes were complicated grief, anxiety, and depression symptoms in relatives; comfort of patients during the dying process; and job strain in staff. RESULTS: We enrolled 212 (85.5%) relatives of 248 patients with terminal weaning and 190 relatives (90.5%) of 210 patients with immediate extubation. Immediate extubation was associated with airway obstruction and a higher mean Behavioural Pain Scale score compared to terminal weaning. In relatives, IES-R scores after 3 months were not significantly different between groups (31.9 ± 18.1 versus 30.5 ± 16.2, respectively; adjusted difference, -1.9; 95% confidence interval, -5.9 to 2.1; p = 0.36); neither were there any differences in complicated grief, anxiety, or depression scores. Assistant nurses had lower job strain scores in the immediate extubation group. CONCLUSIONS: Compared to terminal weaning, immediate extubation was not associated with differences in psychological welfare of relatives when each method constituted standard practice in the ICU where it was applied. Patients had more airway obstruction and gasps with immediate extubation. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01818895.
