Prevalence of unplanned extubation in a tertiary care neonatal intensive care unit.

Orotracheal intubation and mechanical ventilation (MV) have become routine practices in intensive care units. Unplanned extubation (UE) is one of the most important complications, particularly in premature infants and critically ill newborns. The objective of this study was to determine the prevalence of UE in a tertiary care neonatal intensive care unit (NICU). In this analytical cross-sectional retrospective study, all data, including perinatal data, indications for ventilatory support, days of MV at the time of UE, work shift, month of the event, reintubation, and postextubation complications, were obtained from the manual review of clinical charts. In total, 151 neonates, who received invasive MV, were included in this study. The prevalence of UE was 2.0/100 days of ventilation. The most affected were premature infants, with a gestational age of ≤ 32 weeks (54.7%) and a birth weight of ≤ 1500 g. The main cause for UE was deficient fixation of the endotracheal tube (ETT) (27.7%). Most UE events occurred during night shifts (48.1%). Reintubation was required in 83.3% of newborns. Immediate complications developed in 96.3% of the UE events, including desaturation (57.7%) and bradycardia (36.5%). The prevalence of UE was high, particularly in premature infants, with a high rate of reintubation and immediate complications. Standardized protocols for ETT care must be implemented to reduce these events.

Time course of electrical activity of the diaphragm (EAdi) in the peri extubation period and its role as predictor of extubation failure in difficult to wean patients.

INTRODUCTION: Weaning patients from mechanical ventilation is crucial in the management of acute respiratory failure (ARF). Spontaneous breathing trials (SBT) are used to assess readiness for extubation, but extubation failure remains a challenge. Diaphragmatic function, measured by electrical activity of the diaphragm (EAdi), may provide insights into weaning outcomes. MATERIALS AND METHODS: This prospective, observational study included difficult-to-wean patients undergoing invasive mechanical ventilation. EAdi was recorded before, during, and after extubation. Patients were categorized into extubation success and failure groups based on reintubation within 48 h. Statistical analysis assessed EAdi patterns and predictive value. RESULTS: Thirty-one patients were analyzed, with six experiencing extubation failure. Overall, EAdi increased significantly between the phases before the SBT, the SBT and post-extubation period, up to 24 h (p < 0.001). EAdi values were higher in the extubation failure group during SBT (p = 0.01). An EAdi > 30 µV during SBT predicted extubation failure with 92% sensitivity and 67% specificity. Multivariable analysis confirmed EAdi as an independent predictor of extubation failure. CONCLUSIONS: In difficult-to-wean patients, EAdi increases significantly between the phases before the SBT, the SBT and post-extubation period and is significantly higher in patients experiencing extubation failure. An EAdi > 30 µV during SBT may enhance extubation failure prediction compared to conventional parameters. Advanced monitoring of diaphragmatic function could improve weaning outcomes in critical care settings.

Prospective multi-center evaluation of the incidence of unplanned extubation and its outcomes in French intensive care units. The Safe-ICU study.

BACKGROUND: We aimed to determine the epidemiology and outcomes of unplanned extubation (UE), both accidental and self-extubation, in ICU. METHODS: A multicentre prospective cohort study was conducted in 47 French ICUs. The number of mechanical ventilation (MV) days, and planned and unplanned extubation were recorded in each center over a minimum period of three consecutive months to evaluate UE incidence. Patient characteristics, UE environmental factors, and outcomes were compared based on the UE mechanism (accidental or self-extubation). Self-extubation outcomes were compared with planned extubation using a propensity-matched population. Finally, risk factors for extubation failure (re-intubation before day 7) were determined following self-extubation. RESULTS: During the 12-month inclusion period, we found a pooled UE incidence of 1.0 per 100 MV days. UE accounted for 9% of all endotracheal removals. Of the 605 UE, 88% were self-extubation and 12% were accidental-extubations. The latter had a worse prognosis than self-extubation (34% vs. 8% ICU-mortality, p < 0.001). Self-extubation did not increase mortality compared with planned extubation (8% vs. 11%, p = 0.075). Regardless of the type of extubation, planned or unplanned, extubation failure was independently associated with a poor outcome. Cancer, higher respiratory rate, lower PaO2/FiO2 at the time of extubation, weaning process not-ongoing, and immediate post-extubation respiratory failure were independent predictors of failed self-extubation. CONCLUSION: Unplanned extubation, mostly represented by self-extubation, is common in ICU and accounts for 9% of all endotracheal extubations. While accidental extubations are a serious and infrequent adverse event, self-extubation does not increase mortality compared to planned extubation.

Decibel level of coughing as a predictor of extubation outcome in mechanically ventilated intensive care patients: A prospective, observational study.

AIM: This study aims to evaluate the feasibility and clinical utility of measuring cough decibel level as predictive markers for extubation outcomes in mechanically ventilated patients. DESIGN: A prospective observational study. SETTING: Three interdisciplinary medical-surgical intensive care units across China. MAIN OUTCOME MEASURES: The primary outcomes assessed were extubation results in patients. Secondary measures included the cough decibel level, semiquantitative cough intensity scores, and white card test results recorded prior to extubation. RESULTS: A total of 71 patients were included, 55 patients were in the extubation success group and 16 in the failure group. The mean age was 78(71,83) years, mainly male (73.2 %). Despite the baseline characteristics being mostly consistent across both groups, significant differences were noted in duration of mechanical ventilation, and intensive care units and hospital stay. Remarkably, the cough decibel was substantially lower in the extubation failure group compared to the other group (78.69 ± 8.23 vs 92.28 ± 7.01 dB). The Receiver Operating Characteristic curve analysis revealed that a cough decibel below 85.77 dB is the optimal threshold for predicting extubation failure, exhibiting an 80 % sensitivity and 91.67 % specificity. CONCLUSION: The study corroborates that the cough decibel level serves as a quantifiable metric in patients undergoing mechanical ventilation. It posits that the likelihood of extubation failure escalates when the cough decibel falls below 85.77 dB. IMPLICATIONS FOR CLINICAL PRACTICE: Quantification of coughing capacity in decibels may be a good predictor of extubation outcome, thus offering assistance to healthcare professionals in evaluating the readiness of patients for extubation.

Predictive Value of Serial Rapid Shallow Breathing Index Measurements for Extubation Success in Intensive Care Unit Patients.

Background and Objectives: Extubation success in ICU patients is crucial for reducing ventilator-associated complications, morbidity, and mortality. The Rapid Shallow Breathing Index (RSBI) is a widely used predictor for weaning from mechanical ventilation. This study aims to determine the predictive value of serial RSBI measurements on extubation success in ICU patients on mechanical ventilation. Materials and Methods: This prospective observational study was conducted on 86 ICU patients at Hitit University between February 2024 and July 2024. Patients were divided into successful and unsuccessful extubation groups. RSBI values were compared between these groups. Results: This study included 86 patients (32 females, 54 males) with a mean age of 54.51 ± 12.1 years. Extubation was successful in 53 patients and unsuccessful in 33. There was no significant difference in age and intubation duration between the groups (p = 0.246, p = 0.210). Significant differences were found in RSBI-1a and RSBI-2 values (p = 0.013, p = 0.011). The median RSBI-2a was 80 in the successful group and 92 in the unsuccessful group (p = 0.001). The ΔRSBI was higher in the unsuccessful group (p = 0.022). ROC analysis identified optimal cut-off values: RSBI-2a ≤ 72 (AUC 0.715) and ΔRSBI ≤ -3 (AUC 0.648). RSBI-2a ≤ 72 increased the likelihood of successful extubation by 10.8 times, while ΔRSBI ≤ -3 increased it by 3.4 times. Using both criteria together increased the likelihood by 28.48 times. Conclusions: Serial RSBI measurement can be an effective tool for predicting extubation success in patients on IMV. These findings suggest that serially measured RSBI may serve as a potential indicator for extubation readiness.

Situations and Risk Factors of Unplanned Extubation of Nasogastric Tubes in Inpatients: A Retrospective Study.

OBJECTIVE: The aim of the study is to understand whether the risk factors of the unplanned extubation (UE) of nasogastric (NG) tubes vary among different inpatient situations. METHODS: Inpatients who experienced UE between 2009 and 2022 at a medical center were selected, and electronic medical records were used to collect patient background data and their conditions during UE. A total of 302 patients were included in our analysis. RESULTS: Conscious patients were at greater risk of UE when coughing, scratching their nose, blowing their nose, or sneezing than those who were confused (odds ratio [OR] = 0.07, P < 0.001) and those who were drowsy or comatose (OR = 0.15, P = 0.026). During activity, repositioning, bathing, or changing incontinence pads, the risk of UE was higher in patients whose hands were not restrained at the time of UE than in those whose hands were restrained (OR = 0.05, P = 0.004), higher in those with companions than in those without companions (OR = 7.78, P = 0.002), and higher in those with longer NG tube placement time (OR = 1.05, P = 0.008). Accidental extubation (OR = 2.62, P = 0.007) occurred more frequently during activity, repositioning, bathing, or changing incontinence pads. CONCLUSIONS: There is an increased risk of UE in conscious patients during activity, repositioning, bathing, or changing incontinence pads. Patients inserted with an NG tube for a longer period of time were at greater risk of accidental extubation during activity, repositioning, bathing, or changing incontinence pads irrespective of whether a companion could aid them if their hands were or were not restrained.

Evaluating endotracheal tube length in very and extremely preterm infants.

OBJECTIVE: Our study objective was to evaluate changes in ETT tube depth throughout the initial intubation course in very and extremely preterm infants in order to evaluate the risk of outgrowing an endotracheal tube (ETT). METHODS: This was a retrospective cohort study of preterm infants born at <32 weeks of gestation who were admitted to the NICU between 2012 and 2021 and required intubation for mechanical ventilation. Infants who were intubated only for surfactant administration and those with airway malformations were excluded. Descriptive statistics were used to define the range of ETT depths at the time of extubation, stratified by gestational age (<28 weeks vs 28-32 weeks of gestation). Relative ETT depth was defined as the final depth minus the initial depth. RESULTS: Out of 496 infants, 140 patients met all criteria for inclusion. Descriptive analysis of extubation depths across the populations demonstrated median relative ETT depth of 0 cm for the 28-32-week gestational age group, and -0.25 cm for the <28-week gestational age group. The 95th percentile for both gestational age groups was a relative depth of 0.5 cm and the 99th percentile was 1.0-1.5 cm. CONCLUSION: The results of our study suggest that the vast majority of patients in the NICU are unlikely to "outgrow" ETT tube length which should be taken into account when deciding where to trim the ETT in order to minimize airway resistance.

Operating Room Extubation for Patients Undergoing Cardiac Surgery: A National Society of Thoracic Surgeons Database Analysis.

BACKGROUND: The utility of operating room extubation (ORE) after cardiac surgery over fast-track extubation (FTE) within 6 hours remains contested. We hypothesized ORE would be associated with equivalent rates of morbidity and mortality, relative to FTE. METHODS: Patients undergoing nonemergent cardiac surgery were identified in The Society of Thoracic Surgeons Adult Cardiac Surgery Database between July 2017 and December 2022. Only procedures with The Society of Thoracic Surgeons risk models were included. Risk-adjusted outcomes of ORE and FTE were compared by observed-to-expected ratios with 95% CIs aggregated over all procedure types, and ORE vs FTE adjusted odds ratios (ORs) specific to each procedure type using multivariable logistic regression. Analyzed outcomes were operative mortality, prolonged length of stay, composite reoperation for bleeding and reintubation, and composite morbidity and mortality. RESULTS: The study population of 669,099 patients across 1069 hospitals included 36,298 ORE patients in 296 hospitals. Risk-adjusted analyses found that ORE was associated with statistically similar or better results across each of the 4 outcomes and procedure subtypes. Notably, rates of postoperative mortality were significantly lower in ORE patients undergoing coronary artery bypass grafting (OR, 0.54; 95% CI, 0.46-0.65), aortic valve replacement (OR, 0.43; 95% CI, 0.24-0.77), and mitral valve replacement (OR, 0.48; 95% CI, 0.26-0.89). CONCLUSIONS: Extubation in the OR was safe and effective in a selected patient population and may be associated with superior outcomes in coronary artery bypass, aortic valve replacement, and mitral valve replacement. These national data appear to confirm institutional experiences regarding the potential benefit of OR extubation. Further refinement of optimal populations may justify randomized investigation.

Comparative effectiveness of alternative spontaneous breathing trial techniques: a systematic review and network meta-analysis of randomized trials.

BACKGROUND: The spontaneous breathing trial (SBT) technique that best balance successful extubation with the risk for reintubation is unknown. We sought to determine the comparative efficacy and safety of alternative SBT techniques. METHODS: We searched Medline, EMBASE, and the Cochrane Central Register of Controlled Trials from inception to February 2023 for randomized or quasi-randomized trials comparing SBT techniques in critically ill adults and children and reported initial SBT success, successful extubation, reintubation (primary outcomes) and mortality (ICU, hospital, most protracted; secondary outcome) rates. Two reviewers screened, reviewed full-texts, and abstracted data. We performed frequentist random-effects network meta-analysis. RESULTS: We included 40 RCTs (6716 patients). Pressure Support (PS) versus T-piece SBTs was the most common comparison. Initial successful SBT rates were increased with PS [risk ratio (RR) 1.08, 95% confidence interval (CI) (1.05-1.11)], PS/automatic tube compensation (ATC) [1.12 (1.01 -1.25), high flow nasal cannulae (HFNC) [1.07 (1.00-1.13) (all moderate certainty), and ATC [RR 1.11, (1.03-1.20); low certainty] SBTs compared to T-piece SBTs. Similarly, initial successful SBT rates were increased with PS, ATC, and PS/ATC SBTs compared to continuous positive airway pressure (CPAP) SBTs. Successful extubation rates were increased with PS [RR 1.06, (1.03-1.09); high certainty], ATC [RR 1.13, (1.05-1.21); moderate certainty], and HFNC [RR 1.06, (1.02-1.11); high certainty] SBTs, compared to T-piece SBTs. There was little to no difference in reintubation rates with PS (vs. T-piece) SBTs [RR 1.05, (0.91-1.21); low certainty], but increased reintubation rates with PS [RR 2.84, (1.61-5.03); moderate certainty] and ATC [RR 2.95 (1.57-5.56); moderate certainty] SBTs compared to HFNC SBTs. CONCLUSIONS: SBTs conducted with pressure augmentation (PS, ATC, PS/ATC) versus without (T-piece, CPAP) increased initial successful SBT and successful extubation rates. Although SBTs conducted with PS or ATC versus HFNC increased reintubation rates, this was not the case for PS versus T-piece SBTs.

Effect of Reintubation Within 48 Hours on Mortality in Critically Ill Patients After Planned Extubation.

BACKGROUND: Re-intubation is necessary in 2% to 30% of cases of patients receiving a planned extubation. This procedure is associated with prolonged mechanical ventilation, a greater need for tracheostomy, a higher incidence of ventilator-associated pneumonia, and higher mortality. The aim of this study was to evaluate the effect of re-intubation within 48 h on mortality after planned extubation by using a randomized controlled trial database. METHODS: Secondary analysis of a multi-center randomized trial, which evaluated the effect of reconnection to mechanical ventilation for 1 h after a successful spontaneous breathing trial, followed by extubation. The study included adult subjects who received invasive mechanical ventilation for > 12 h. The subjects were divided into an extubation failure group and an extubation success group. The outcome was in-hospital mortality. Two multivariate logistic regression models were constructed to identify independent factors associated with mortality. RESULTS: Among the 336 subjects studied, extubation failed in 52 (15.4%) and they were re-intubated within 48 h. Most re-intubations occurred between 12 and 24 h after planned extubation (median [interquartile range] 16 [6-36] h). Mortality of the extubation failure group was higher both in the ICU (32.6% vs 6.6%; odds ratio [OR] 6.77, 95% CI 3.22-14.24; P < .001) and in-hospital (42.3% vs 14.0%; OR 4.47, 95% CI 2.34-8.51; P < .001) versus the extubation success group. Multivariate logistic regression analyses showed that re-intubation within 48 h was independently associated with both ICU mortality (OR 6.10, 95% CI 2.84-13.07; P < .001) and in-hospital mortality (OR 3.36, 95% CI 1.67-6.73; P = .001). In-hospital mortality was also associated with rescue noninvasive ventilation after extubation (OR 2.44, 95% CI 1.25-4.75; P = .009). CONCLUSIONS: Re-intubation within 48 h after planned extubation was associated with mortality in subjects who were critically ill.

Early Extubation: Who Qualifies Postoperatively in Lung Transplantation?

INTRODUCTION: Early extubation has been adopted in many settings within cardiothoracic surgery, with several advantages for patients. We sought to determine the association of timing of extubation in lung transplant recipients' short- and long-term outcomes. METHODS: Adult, primary lung transplants were identified from the United Network for Organ Sharing database. Recipients were stratified based on the duration of postoperative ventilation: 1) None (NV); 2) <5 Days (<5D); and 3) 5+ Days (5+D). Comparative statistics were performed, and both unadjusted and adjusted survival were analyzed with Kaplan-Meier Methods and a Cox proportional hazard model. A multivariable model including recipient, donor, and transplant characteristics was created to examine factors associated with NV. RESULTS: 28,575 recipients were identified (NV = 960, <5D = 21,959, 5+D = 5656). The NV group had shorter median length of stay (P < 0.01) and lower incidence of postoperative dialysis (P < 0.01). The NV and <5D groups had similar survival, while 5+D recipients had decreased survival (P < 0.01). The multivariable model demonstrated increased donor BMI, center volume, ischemic time, single lung transplant, and transplantation between 2011 and 2015 were associated with NV (P < 0.01 for all). Use of donation after cardiac death donors and transplantation between 2016 and 2021 was associated with postoperative ventilator use. CONCLUSIONS: Patients extubated early after lung transplantation have a shorter median length of stay without an associated increase in mortality. While not all patients are appropriate for earlier extubation, it is possible to extubate patients early following lung transplant. Further efforts are necessary to help expand this practice and ensure its' success for recipients.

High-flow nasal cannula in Spanish Pediatric Intensive Care Services: A national web survey about its use and indications.

OBJECTIVE: To describe the high-flow nasal cannula (HFNC) indications in the Spanish pediatric critical care units (PICUs). DESIGN: Descriptive cross-sectional observational study. SETTING: Electronic survey among members of the Spanish Society of Pediatric Intensive Care (SECIP). It was sent weekly from April 10, 2023, to May 21, 2023. PARTICIPANTS: All SECIP members. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: The questions focused on workplace, years of experience, use or non-use of HFNC, justification and expectations regarding its application, starting point within each center, clinical criteria for indication, existence of clinical guidelines, evaluation during its use, and criteria and mode of withdrawal. RESULTS: Two hundred and two participants, 176 were from Spain. Of these, 87/176 had over ten years of experience. One hundred sixty two use HFNC and 66/162 have HFNC clinical guidelines. Acute bronchiolitis (138/162) and respiratory assistance after extubation (106/56) are the two main indications. For 62/162 HFNC may reduce therapeutic escalation. Neuromuscular diseases (105/162) and anatomical airway diseases (135/162) are the two main contraindications. The reasons to do not use HFNC were the absence of evidence about it effectiveness (8/14) and its inadequate cost/effectiveness balance (8/14). CONCLUSIONS: A majority of Spanish pediatric intensivists use HFNC. Its application and withdrawal appears to be primarily based on clinical experience. Besides, those who use HFNC are aware of its limitations and the lack of evidence in some cases. It is necessary to develop single-center and multicenter studies to elucidate the effectiveness of this therapy in the context of critically ill children.

Evaluating the Sum of Eye and Motor Components of the Glasgow Coma Score As a Predictor of Extubation Failure in Patients With Acute Brain Injury.

OBJECTIVES: To evaluate the association between the pre-extubation sum of eye and motor components of the Glasgow Coma Score (GCS-EM) and odds of extubation failure in patients with acute brain injury being liberated from mechanical ventilation. DESIGN: Secondary analysis of a prospective, multicenter observational study ( ClinicalTrials.gov identifier NCT03400904). SETTING: Sixty-three hospital sites worldwide, with patient recruitment from January 2018 to November 2020. PATIENTS: One thousand one hundred fifty-two critically ill patients with acute brain injury, with a median age of 54 years, of whom 783 (68.0%) were male, 559 (48.5%) had traumatic brain injury, and 905 (78.6%) had a GCS-EM greater than 8 before extubation (scores range from 2 to 10). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: GCS-EM was computed in intubated patients on the day of extubation. The main outcome was extubation failure, defined as unplanned reintubation within 5 days of extubation. Analyses used multilevel logistic regression with adjustment for patient characteristics and a random intercept for hospital site. In the primary analysis, GCS-EM was not associated with extubation failure (odds ratio, 1.07 per additional point; 95% CI, 0.87-1.31). Findings were consistent in sensitivity analyses that: 1) used different adjustment covariates, 2) included a verbal estimate to derive an overall GCS, 3) accounted for missing data, 4) considered a 2-day time interval to define extubation failure, 5) accounted for competing risks, and 6) used a propensity score-based model. There was no association between GCS-EM and extubation outcome in subgroups defined by brain injury diagnosis or age. CONCLUSIONS: In this large, contemporary, multicenter cohort of patients with acute brain injury, we found no association between the GCS-EM and odds of extubation failure. However, few patients had a pre-extubation GCS-EM less than or equal to 8, and the possibility of a true prognostic association in patients with low scores is not excluded.

Respiratory outcomes and survival after unplanned extubation in the NICU: a prospective cohort study from the SEPREVEN trial.

OBJECTIVE: To compare reintubation rates after planned extubation and unplanned extubation (UE) in patients in neonatal intensive care units (NICUs), to analyse risk factors for reintubation after UE and to compare outcomes in patients with and without UE. DESIGN: Prospective, observational study nested in a randomised controlled trial (SEPREVEN/Study on Epidemiology and PRevention of adverse EVEnts in Neonates). Outcomes were expected to be independent of the intervention tested. SETTING: 12 NICUs in France with a 20-month follow-up, starting November 2015. PATIENTS: n=2280 patients with a NICU stay >2 days, postmenstrual age ≤42 weeks on admission. INTERVENTIONS/EXPOSURE: Characteristics of UE (context, timing, sedative administration in the preceding 6 hours, weaning from ventilation at time of UE) and patients. MAIN OUTCOME MEASURES: Healthcare professional-reported UE rates, reintubation/timing after extubation, duration of mechanical ventilation, mortality and bronchopulmonary dysplasia (BPD). RESULTS: There were 162 episodes of UE (139 patients, median gestational age (IQR) 27.3 (25.6-31.7) weeks). Cumulative reintubation rates within 24 hours and 7 days of UE were, respectively, 50.0% and 57.5%, compared with 5.5% and 12.3% after a planned extubation. Independent risk factors for reintubation within 7 days included absence of weaning at the time of UE (HR, 95% CI) and sedatives in the preceding 6 hours (HR 1.93, 95% CI 1.04 to 3.60). Mortality at discharge did not differ between patients with planned extubation or UE. UE was associated with a higher risk of BPD. CONCLUSION: In the SEPREVEN trial, reintubation followed UE in 58% of the cases, compared with 12% after planned extubation. TRIAL REGISTRATION NUMBER: NCT02598609.

Predicting delayed extubation and transfer to the intensive care unit in children undergoing posterior fusion surgery for scoliosis : A retrospective observational study.

BACKGROUND: Delayed extubation and transfer to the intensive care unit (ICU) in children undergoing major scoliosis surgery may increase postoperative complications, prolong hospital stay, and increase medical expenses; however, whether a child will require delayed extubation or transfer to the ICU after scoliosis orthopedic surgery is not fully understood. In this study, we reviewed the risk factors for delayed extubation and transfer to the ICU after scoliosis orthopedic surgery in children. METHOD: The electronic medical records of pediatric patients (≤ 18 years) who underwent posterior spinal fusion surgery between January 2018 and November 2021 were reviewed and analyzed. Patient characteristics (age, sex, body mass index, American Society of Anesthesiologists, ASA, grade, preoperative lung function, and congenital heart disease), preoperative Cobb angle, scoliosis type, correction rate, vertebral fusion segments, pedicle screws, surgical osteotomy, intraoperative bleeding, intraoperative allogeneic transfusion, intraoperative hemoglobin changes, intraoperative mean arterial pressure changes, intraoperative tidal volume (ml/kg predicted body weight), surgical time, postoperative extubation, and transfer to the ICU were collected. The primary outcomes were delayed extubation and transfer to the ICU. Multivariate logistic regression models were used to determine the risk factors for delayed extubation and ICU transfer. RESULTS: A total of 246 children who satisfied the inclusion criteria were enrolled in this study, of whom 23 (9.3%) had delayed extubation and 81 (32.9%) were transferred to the ICU after surgery. High ASA grade (odds ratio [OR] 5.42; 95% confidence interval [CI] 1.49-19.78; p = 0.010), high Cobb angle (OR 1.04; 95% CI 1.02-1.07; p < 0.001), moderate to severe pulmonary dysfunction (OR 10.9; 95% CI 2.00-59.08; p = 0.006) and prolonged surgical time (OR 1.01; 95% CI 1.00-1.03; p = 0.040) were risk factors for delayed extubation. A high Cobb angle (OR 1.02; 95% CI 1.01-1.04; p = 0.004), high intraoperative bleeding volume (OR 1.06; 95% CI 1.03-1.10; p = 0.001), allogeneic transfusion (OR 3.30; 95% CI 1.24-8.83; p = 0.017) and neuromuscular scoliosis (OR 5.38; 95% CI 1.59-18.25; p = 0.007) were risk factors for transfer to the ICU. A high Cobb angle was a risk factor for both delayed extubation and ICU transfer. Age, sex, body mass index, number of vertebral fusion segments, correction rate, and intraoperative tidal volume were not associated with delayed postoperative extubation and ICU transfer. CONCLUSION: The most common risk factor for delayed extubation and ICU transfer in pediatric patients who underwent posterior spinal fusion was a high Cobb angle. Determining risk factors for a poor prognosis may help optimize perioperative respiratory management strategies and planning of postoperative care for children undergoing complicated spinal surgery.

Can critical care transport be safely reduced in children intubated during emergency management of status epilepticus in the United Kingdom: a national audit with case-control analysis.

OBJECTIVE: This study describes the baseline clinical characteristics, predictors of successful extubation at referring hospitals and short-term outcomes of children intubated for status epilepticus and referred to United Kingdom (UK) paediatric critical care transport teams (PCCTs). DESIGN: Multicentre audit with case-control analysis, conducted between 1 September 2018 and 1 September 2020. SETTING: This study involved 10 UK PCCTs. PATIENTS: Children over 1 month of age intubated during emergency management for status epilepticus (SE), referred to UK PCCTs. Patients with trauma, requiring time-critical neurosurgical intervention or those with a tracheostomy were excluded. INTERVENTIONS: No interventions were implemented. MEASUREMENTS AND MAIN RESULTS: Out of the 1622 referrals for SE, 1136 (70%) were intubated at referral. The median age was 3 years (IQR 1.25-6.54 years). Among the intubated children, 396 (34.8%) were extubated locally by the referring team, with 19 (4.8%) requiring reintubation. Therefore, the overall rate of successful extubation was 33% (377/1136). There was significant variation between PCCTs, with local extubation rates ranging from 2% to 74%. Multivariable analyses showed region/PCCT, contributing diagnosis, acute changes on CT, preceding encephalopathy and type of continuous sedation (midazolam) used postintubation were significantly associated with transfer to a critical care unit. CONCLUSION: This study highlights wide regional variation in early extubation practices. Regions with high successful extubation rates have established extubation guidelines from PCCTs. Successful extubation represents critical care transports that have been avoided.

A quality improvement strategy to reduce unintended extubation in the very low birth weight infant: A case report.

BACKGROUND: Unintended extubations remain a common complication across neonatal intensive care units, with very low birthweight infants being the most vulnerable of them all. Ongoing efforts across different institutions exist with the goal of reducing the rate of unintended extubations to keep a median rate of <2 events per 100 ventilator days as defined by the Vermont Oxford Network. Our objective was to reduce unintended extubations in the very low birthweight infant in a large delivery hospital to ≤2/100 ventilator days. METHODS: A collaborative group was formed between two academic health institutions targeting training and implementation of the Children's National unintended extubation system, focusing on endotracheal tube securement methods and surveillance protocols. RESULTS: The unintended extubation rate decreased from 3.23 to 0.64 per 100 ventilator days. Changes were implemented from 2018-2020 with a sustained reduction in the unintended extubation rate of 1.54 per 100 ventilator days. Most events occurred between 12 : 00 pm -4 : 00 pm and the commonest cause was spontaneous (25%) followed by dislodgment during repositioning (19%). CONCLUSION: Very low birth weight infants present a challenge to endotracheal tube maintenance due to their developmental and anatomical changes during their neonatal intensive care unit stay. Successful reduction of unintended extubations in the very low birthweight infant can be achieved by adaptation of successful protocols for older infants.

Utilización de soportes respiratorios no invasivos post extubación en pacientes adultos críticos: revisión narrativa SRNI post extubación en adultos críticos / Use of Non-Invasive Respiratory Support in Critically Ill Patients Post-Extubation: a Narrative Review NIRS Post-Extubation in Critically Ill Adults

La tasa de reintubación orotraqueal luego de la extubación se registra entre un 10 a 20%. La aplicación de soportes respiratorios no-invasivos (SRNI) posterior a la extuba-ción como cánula nasal de alto-flujo, ventilación no invasiva (dos niveles de presión) y presión positiva continua en la vía aérea demostraron ser seguras y efectivas post ex-tubación. El período pre-destete representa un momento crucial en el manejo de los pa-cientes críticos ya que el fracaso de la extubación, definido como la necesidad de reintu-bación dentro de los 2 a 7 días, demostró peores resultados al aumentar la mortalidad entre un 25-50%. Esta situación conlleva al requerimiento de ventilación mecánica prolongada, neumonía asociada a la ventilación mecánica y estancias prolongadas de internación. Por lo tanto, es esencial identificar a los pacientes que se beneficiarán utilizando SRNI post extubación.

The rate of re-intubation after extubation is recorded at 10-20%. The use of non-invasive respiratory support (NIRS) post-extubation such as high-flow nasal cannula, non-invasive ventilation (bilevel pressure) and continuous positive airway pressure (CPAP) have been shown to be safe and effective post-extubation. The pre-weaning period represents a crucial time in the management of critically ill patients, as extubation failure, defined as the need for reintubation within 2-7 days, showed worse outcomes with mortality increasing by 25-50%. This situation leads to the requirement for prolonged mechanical ventilation, ventilator-associated pneumonia and long lengths of hospital stay. Therefore, it is essential to identify patients who will benefit from NIRS post extubation.
