Abstract
BACKGROUND Early extubation (EEx) is defined as the removal of the endotracheal tube within 8 h postoperatively. The present study involved determining the availability and threshold of the vasoactive-inotropic score (VIS) for predicting EEx in adults after elective rheumatic heart valve surgery. METHODS The present study was designed as a single-center retrospective cohort study which was conducted with adults who underwent elective rheumatic heart valve surgery with CPB. The highest VIS in the immediate postoperative period was used in the present study. The primary outcome, the availability of VIS for EEx prediction and the optimal threshold value were determined using ROC curve analysis. The gray zone analysis of the VIS was performed by setting the false negative or positive rate R = 0.05, and the perioperative risk factors for prolonged EEx were identified by multivariate logistic analysis. The postoperative complications and outcomes were compared between different VIS groups. RESULTS Among the 409 patients initially screened, 379 patients were ultimately included in the study. The incidence of EEx was determined to be 112/379 (29.6%). The VIS had a good predictive value for EEx (AUC = 0.864, 95% CI: [0.828, 0.900], P < 0.001). The optimal VIS threshold for EEx prediction was 16.5, with a sensitivity of 71.54% (65.85-76.61%) and a specificity of 88.39% (81.15-93.09%). The upper and lower limits of the gray zone for the VIS were determined as (12, 17.2). The multivariate logistic analysis identified age (OR, 1.060; 95% CI: 1.017-1.106; P = 0.006), EF% (OR, 0.798; 95% CI: 0.742-0.859; P < 0.001), GFR (OR, 0.933; 95% CI: 0.906-0.961; P < 0.001), multiple valves surgery (OR, 4.587; 95% CI: 1.398-15.056; P = 0.012), and VIS > 16.5 (OR, 12.331; 95% CI: 5.015-30.318; P < 0.001) as the independent risk factors for the prolongation of EEx. The VIS ≤ 16.5 group presented a greater success rate for EEx, a shorter invasive ventilation support duration, and a lower incidence of complications than did the VIS > 16.5 group, while the incidence of reintubation was similar between the two groups. CONCLUSION In adults, after elective rheumatic heart valve surgery, the highest VIS in the immediate postoperative period was a good predictive value for EEx, with a threshold of 16.5.

Abstract
OBJECTIVES This study aimed to investigate and compare the effects of the pectointercostal fascial plane block (PIFPB) and the erector spinae plane block (ESPB) on enhancing the recovery of patients who undergo cardiac surgery. DESIGN A randomized, controlled, double-blinded study. SETTING The operating rooms and intensive care units of university hospitals. PARTICIPANTS One hundred patients who were American Society of Anesthesiologists class II to III aged 18-to-70 years scheduled for elective cardiac surgery. INTERVENTIONS Patients were randomly assigned to undergo either ultrasound-guided bilateral PIFPB or ESPB. MEASUREMENTS AND MAIN RESULTS Patients shared comparable baseline characteristics. Time to extubation, the primary outcome, did not demonstrate a statistically significant difference between the groups, with median (95% confidence interval) values of 115 (90-120) minutes and 110 (100-120) minutes, respectively (p = 0.875). The ESPB group had a statistically significant reduced pain score postoperatively. The median (IQR) values of postoperative fentanyl consumption were statistically significantly lower in the ESPB group than in the PIFPB group (p < 0.001): 4 (4-5) versus 9 (9-11) µg/kg, respectively. In the ESPB group, the first analgesia request was given 4 hours later than in the PIFPB group (p < 0.001). Additionally, 12 (24%) patients in the PIFPB group reported nonsternal wound chest pain, compared with none in the ESPB group. The median intensive care unit length of stay for both groups was 3 days (p = 0.428). CONCLUSIONS Erector spinae plane block and PIFPB were found to equally affect recovery after cardiac surgery, with comparable extubation times and intensive care unit length of stay.

Abstract
BACKGROUND The prevention of unplanned endotracheal extubation (UEE) is significant for the critical care of intensive care unit (ICU) patients. AIM To develop a questionnaire to assess the knowledge, attitude, and practice (KAP) of the nurses regarding of the prevention of UEE in ICU patients with transoral endotracheal intubation (TEI) and to test the validity and reliability of the questionnaire. STUDY DESIGN Items relevant to KAP were prepared following a literature review, and then screened using a Delphi expert consultation, pre-test, and factor analysis. The nursing staffs in four tertiary hospitals in Qinghai, Jiangsu, Gansu, and Shandong provinces were surveyed to test the reliability and validity of the questionnaire. RESULTS The questionnaire contained 76 items, including 10, 37, and 29 in the dimensions of knowledge, attitude, and practice, respectively. The scale-level content validity index (S-CVI) of the questionnaire was 0.96. The results of exploratory factor analysis (EFA) showed that the Kaiser-Meyer-Olkin value was 0.956, indicating that the sample was adequate and suitable for factor analysis. The result of the Bartlett spherical test was significant (p < .001), indicating that the questionnaire was suitable for further EFA. A total of six common factors were extracted by EFA with a cumulative variance interpretation rate of 85.52%, indicating that the questionnaire had good structural validity. The Cronbach's alpha was 0.981 for the whole questionnaire; and was 0.966, 0.996, and 0.981 for the dimensions of knowledge, attitude, and practice, respectively. The test-retest reliability for the questionnaire was 0.843. CONCLUSIONS The developed questionnaire has good reliability and validity and can be used as a scientific tool for the nursing leaders to prevent UEE in ICU patients with TEI. RELEVANCE TO CLINICAL PRACTICE The instrument provides a theoretical reference for establishing preventive strategies and management programs in clinical practice.

Abstract
Tremendous advancements in neonatal respiratory care have contributed to the improved survival of extremely preterm infants (gestational age ≤ 28 weeks). While mechanical ventilation is often considered one of the most important breakthroughs in neonatology, it is also associated with numerous short and long-term complications. For those reasons, clinical research has focused on strategies to avoid or reduce exposure to mechanical ventilation. Nonetheless, in the extreme preterm population, 70-100% of infants born 22-28 weeks of gestation are exposed to mechanical ventilation, with nearly 50% being ventilated for ≥ 3 weeks. As contemporary practices have shifted towards selectively reserving mechanical ventilation for those patients, mechanical ventilation weaning and extubation remain a priority yet offer a heightened challenge for clinicians. In this review, we will summarize the evidence for different strategies to expedite weaning and assess extubation readiness in preterm infants, with a particular focus on extremely preterm infants.

Abstract
OBJECTIVE To analyze the optimal postextubation respiratory support in pediatric cardiac surgery patients. DESIGN Systematic review of randomized controlled trials. SETTING Pediatric or neonatal intensive care units. PARTICIPANTS All aged children (<16 years) having cardiac surgery and postoperative invasive ventilation. INTERVENTION Noninvasive respiratory support, including high flow nasal cannula (HFNC), conventional oxygen therapy (COT), noninvasive positive pressure ventilation (NIPPV), continuous positive pressure (CPAP), and noninvasive high-frequency oscillatory ventilation (NHFOV). MEASUREMENT AND MAIN RESULTS Studies were not pooled for statistical synthesis due to the limited number and quality of the included studies. Risk ratios with 95% confidence intervals were calculated for individual studies. A total of 167 studies were screened and six were included. The risk of bias was low in one, high in one, and had some concerns in four of the studies. Extubation failure (defined as reintubation) was the main outcome of interest. Risk ratio for reintubation was 0.10 (CI 0.02-0.40) and 1.07 (CI 0.16-7.26) in HFNC versus COT, 0.49 (CI 0.05-5.28) in HFNC versus NIPPV, 0.40 (CI 0.08-1.94) in HFNOV versus CPAP, 0.75 (CI 0.26-2.18) in HFNOV versus NIPPV, and 1.37 (CI 0.33-5.73) in CPAP versus NIPPV. Treatment durations did not differ between the groups. CONCLUSION We did not find clear evidence of a difference in reintubation rates and other clinical outcomes between different noninvasive ventilation strategies. Evidence certainty was assessed to be very low due to the risk of bias, the small number of included studies, and high imprecision. Future quality studies are needed to determine the optimal postextubation support in pediatric cardiac surgery patients.

Abstract
OBJECTIVE Terminal extubation (TE) and terminal weaning (TW) during withdrawal of life-sustaining therapies (WLSTs) have been described and defined in adults. The recent Death One Hour After Terminal Extubation study aimed to validate a model developed to predict whether a child would die within 1 hour after discontinuation of mechanical ventilation for WLST. Although TW has not been described in children, pre-extubation weaning has been known to occur before WLST, though to what extent is unknown. In this preplanned secondary analysis, we aim to describe/define TE and pre-extubation weaning (PW) in children and compare characteristics of patients who had ventilatory support decreased before WLST with those who did not. DESIGN Secondary analysis of multicenter retrospective cohort study. SETTING Ten PICUs in the United States between 2009 and 2021. PATIENTS Nine hundred thirteen patients 0-21 years old who died after WLST. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS 71.4% ( n = 652) had TE without decrease in ventilatory support in the 6 hours prior. TE without decrease in ventilatory support in the 6 hours prior = 71.4% ( n = 652) of our sample. Clinically relevant decrease in ventilatory support before WLST = 11% ( n = 100), and 17.6% ( n = 161) had likely incidental decrease in ventilatory support before WLST. Relevant ventilator parameters decreased were F io2 and/or ventilator set rates. There were no significant differences in any of the other evaluated patient characteristics between groups (weight, body mass index, unit type, primary diagnostic category, presence of coma, time to death after WLST, analgosedative requirements, postextubation respiratory support modality). CONCLUSIONS Decreasing ventilatory support before WLST with extubation in children does occur. This practice was not associated with significant differences in palliative analgosedation doses or time to death after extubation.

Abstract
BACKGROUND Unintended extubation (UE) is a serious risk associated with endotracheal intubation. In the paediatric population, UE can lead to significant patient harm. On average, each UE increases ICU and hospital length of stay by 5.5 and 6.5 days respectively and costs an additional $36 000. The international benchmark rate of UE for quality analysis cited in the literature is <1 per 100 ventilator days. The United States organization Solutions for Patient Safety (SPS) developed and introduced a bundle to reduce UE with a goal of ≤0.95 per 100 ventilator days. AIM The aim of this quality improvement project was to determine the baseline rate of UE in a 20-bed mixed medical/surgical PICU in the Pacific Northwest of the United States, implement the SPS bundle for UE prevention, and assess adherence to the bundle, and subsequent rate of UE. STUDY DESIGN The IHI Model for Improvement Plan-Do-Study-Act (PDSA) was used to guide the development, implementation, and assessment of the SPS UE Bundle standardizing the management of endotracheal tubes. Adherence to the bundle was measured through peer-to-peer audits. Rates of adherence and UE were monitored on line charts. RESULTS Baseline rate of UE was 1.83 per 100 ventilator days; 23 weeks post implementation of the bundle the rate of UE was reduced to 0.38 UE per 100 ventilator days, F(7, 9) = 4.685, p = 0.027. The mean bundle adherence was 92%. CONCLUSIONS This quality improvement initiative confirms that high adherence to the SPS UE Bundle may significantly reduce rates of UE in PICU settings. RELEVANCE TO CLINICAL PRACTICE Use of the SPS evidence-based discrete UE bundle and high adherence to the bundle can standardize practise and may reduce unintended extubation in the paediatric population.

Abstract
BACKGROUND The primary objective of this study was to identify specific factors in pediatric cardiac surgical patients when tracheal extubation was performed on the operating table after completion of open-heart surgery (Group-1), postoperatively in the intensive care unit within 6 h (Group-II) or after 6 h (Group-III). The causes of failed extubation, the presence of chromosomal disorders in addition to arterial blood gas analysis parameters at the time of tracheal extubation, and the duration of intensive care unit stay were also evaluated in each group. METHODS In addition to the three groups, Groups I and II were combined as a "fast-track" extubation group. The demographic data, Risk Adjustment for Congenital Heart Surgery (RACHS-1) score, the Society of Thoracic Surgeons - European Association for Cardio-Thoracic Surgery Congenital Heart Surgery Mortality Category (STAT Mortality Category), cardiopulmonary bypass (CPB) time, aortic cross-clamp (ACC) time, and vasoactive-inotropic score (VIS) at the time of tracheal extubation along with data related to secondary objectives were recorded for each patient. RESULTS A significant association was found by bivariate analysis between clinical variables and for both operating table and fast-track extubation in terms of age, weight, RACHS-1 score, STAT category, CPB and ACC time, and VIS. A multivariate-adjusted analysis showed weight, lower STAT category, CPB time, and VIS were independent predictors for operating table and fast-track extubation. CONCLUSIONS Younger age, lower weight, higher RACHS-1, STAT category, and VIS, along with longer CPB and ACC, are associated with delay in the timing of tracheal extubation in pediatric cardiac surgical patients.

Abstract
BACKGROUND Respiratory responses to extubation can cause serious postoperative complications. Beta-blockers, such as metoprolol, can interfere with the cough pathway. However, whether metoprolol can effectively control respiratory reflexes during extubation remains unclear. The objective of this study is to evaluate the efficacy of intravenous metoprolol in attenuating respiratory responses to tracheal extubation. METHODS Randomized, double-blinded, placebo-controlled trial. SETTING Tertiary referral center located in Brasília, Brazil. Recruitment: June 2021 to December 2021. SAMPLE 222 patients of both sexes with an American Society of Anesthesiologists (ASA) physical status I-III aged 18-80 years. Patients were randomly assigned to receive intravenous metoprolol 5 mg IV or placebo at the end of surgery. The primary outcome was the proportion of patients who developed bucking secondary to endotracheal tube stimulation of the tracheal mucosa during extubation. Secondary outcomes included coughing, bronchospasm, laryngospasm, Mean Blood Pressure (MAP), and Heart Rate (HR) levels. RESULTS Two hundred and seven participants were included in the final analysis: 102 in the metoprolol group and 105 in the placebo group. Patients who received metoprolol had a significantly lower risk of bucking (43.1% vs. 64.8%, Relative Risk [RR = 0.66], 95% Confidence Interval [95% CI 0.51-0.87], p = 0.003). In the metoprolol group, 6 (5.9%) patients had moderate/severe coughing compared with 33 (31.4%) in the placebo group (RR = 0.19; 95% CI 0.08-0.43, p < 0.001). CONCLUSION Metoprolol reduced the risk of bucking at extubation in patients undergoing general anesthesia compared to placebo.

Abstract
OBJECTIVES Few data are available regarding early extubation after mitral valve surgery. We sought to assess the impact of an enhanced recovery after surgery-based protocol-ultra-fast-track protocol-in patients undergoing minimally invasive transaxillary mitral valve surgery. METHODS Data of patients who underwent transaxillary mitral valve surgery associated with ultra-fast-track protocol between 2018 and 2023 were reviewed. We compared preoperative, intraoperative and postoperative data of patients who had fast-track extubation (≤6 h since the end of the procedure) and non-fast-track extubation (>6 h) and, within the fast-track group, patients who underwent on-table extubation and patients who were extubated in intensive care unit within 6 h. Multivariable logistic regression was used to study the association of extubation timing and intensive care unit stay, postoperative stay and discharge home. RESULTS Three hundred fifty-six patients were included in the study. Two hundred eighty-two patients underwent fast-track extubation (79%) and 160 were extubated on table (45%). We found no difference in terms of mortality and occurrence of major complications (overall mortality and cerebral stroke 0.3%) according to the extubation timing. Fast-track extubation was associated with shorter intensive care unit stay, discharge home and discharge home within postoperative day 7 when compared to non-fast-track extubation. Within the fast-track group, on-table extubation was associated with intensive care unit stay ≤1 day and discharge home within postoperative day 7. CONCLUSIONS Fast-track extubation was achievable in most of the patients undergoing transaxillary minimally invasive mitral valve surgery and was associated with higher rates of day 1 intensive care unit discharge and discharge home. On-table extubation was associated with further reduced intensive care unit stay and hospitalization.

Abstract
BACKGROUND Static lung compliance, which is seriously affected during surgery, can lead to respiratory failure and extubation failure, which is little explored in the decision to extubate after cardiac surgery. OBJECTIVE To evaluate static lung compliance in the postoperative period of cardiac surgery and relate its possible reduction to cases of extubation failure in patients submitted to the fast-track method of extubation. METHODS Patients undergoing cardiac surgery using cardiopulmonary bypass (CPB) at a state university hospital admitted to the ICU under sedation and residual block were included. Their static lung compliance was assessed on the mechanical ventilator using software that uses least squares fitting (LSF) for measurement. Within 48 hours of extubation, the patients were observed for the need for reintubation due to respiratory failure. The level of significance adopted for the statistical tests was 5%, i.e., p<0.05. RESULTS 77 patients (75.49%) achieved successful extubation and 25 (24.51%) failed extubation. Patients who failed extubation had lower static lung compliance compared to those who succeeded (p<0.001). We identified the cut-off point for compliance through analysis of the Receiver Operating Characteristic Curve (ROC), with the cut-off point being compliance <41ml/cmH2O associated with a higher probability of extubation failure (p<0.001). In the multiple regression analysis, the influence of lung compliance (divided by the ROC curve cut-off point) was found to be 9.1 times greater for patients with compliance <41ml/cmH2O (p< 0.003). CONCLUSIONS Static lung compliance <41ml/cmH2O is a factor that compromises the success of extubation in the postoperative period of cardiac surgery.

OBJECTIVE To systematically review: 1) peri-extubation settings; and 2) association between peri-extubation settings and outcomes in preterm neonates. STUDY DESIGN In this systematic review, studies were eligible if they reported patient-data on peri-extubation settings (objective 1) and/or evaluated peri-extubation levels in relation to clinical outcomes (objective 2). Data were meta-analyzed when appropriate using random-effects model. RESULTS Of 9681 titles, 376 full-texts were reviewed and 101 included. The pooled means of peri-extubation settings were summarized. For objective 2, three experimental studies were identified comparing post-extubation CPAP levels. Meta-analyses revealed lower odds for treatment failure [pooled OR 0.46 (95% CI 0.27-0.76); 3 studies, 255 participants] but not for re-intubation [pooled OR 0.66 (0.22-1.97); 3 studies, 255 participants] with higher vs. lower CPAP. CONCLUSIONS Summary of peri-extubation settings may guide clinicians in their own practices. Higher CPAP levels may reduce extubation failure, but more data on peri-extubation settings that optimize outcomes are needed.

Abstract
AIMS This study aims to describe our refined technique of submental intubation to avoid the recorded intraoperative complications related to tube passage and pilot balloon rupture. CASE SERIES This is a retrospective case series of 21 patients with complex maxillofacial trauma who underwent submental intubation from January 2019 to January 2023. All the patients underwent to the same procedure with a new technique of pilot balloon protection: the pilot balloon was not deflated because, once the connector was removed, only the tube was curved and passed through the incision extraorally while the cuff remained inflated. The wire of the pilot balloon was passed behind the last tooth so as not to interfere with the maxillary-mandibular fixation, remaining extraorally under the anesthetist's view. DISCUSSION Only 2 patients (9.5%) reported complications related to submental intubation: in particular a patient (4.8%) reported oral floor infection, and in another patient (4.8%) an unesthetic skin scar was observed. No patients reported intraoperative complications related to the procedure. CONCLUSION The technique of pilot balloon protection that we have proposed seems to be effective in reducing the intraoperative complications related to the passage of the pilot balloon, such as rupture, damage or early extubation.

[PMID: 37783181 DOI: 10.1016/j.iccn.2023.103551] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 09/06/2023] [Accepted: 09/11/2023] [Indexed: 10/04/2023]
Abstract
OBJECTIVE This meta-analysis aimed to assess the predictive value of the rapid shallow breathing index for extubation outcomes. METHODOLOGY We conducted a systematic review of literature (inception to March 2023) and a meta-analysis. Statistical analysis was performed using Meta-Disc 1.4 software, RevMan 5.4 software and Stata 14.0 software to evaluate the predictive value of RSBI for extubation outcomes. RESULTS A total of 1,987 studies were retrieved, and after applying the inclusion criteria, 79 studies were included in the final analysis, involving 13,170 patients undergoing mechanical ventilation. The random-effects model was employed for statistical analysis. The summary receiver operating characteristic curves (SROC) area under the curve (AUC) was 0.8144. The pooled sensitivity was 0.60 (95% CI: 0.59, 0.61), the pooled specificity was 0.68 (95% CI: 0.66, 0.70). CONCLUSIONS The Rapid Shallow Breathing Index demonstrated moderate accuracy, poor pooled sensitivity and specificity in predicting successful extubation, however the study does not present adequate data to support or reject the use of this tool as a single parameter that predicts extubation outcome. Future studies should explore the combination of The Rapid Shallow Breathing Index with other indicators and clinical experience to improve the success rate of extubation and reduce the risk of extubation failure. IMPLICATIONS FOR CLINICAL PRACTICE Premature and delayed extubation in mechanically ventilated patients can have a negative impact on prognosis and prolong hospital stay. The Rapid Shallow Breathing Index is a simple, cost-effective, and easily monitored objective evaluation index, which can be used to predict the outcome of extubation, especially in primary hospitals. Our study comprehensively evaluated the value of this tool in predicting extubation outcomes, which can help clinicians combine subjective experience with objective indicators to improve the accuracy of extubation time decisions.

Abstract
BACKGROUND Following the opening of an infant cardiac neonatal intensive care unit, our aim was to determine a baseline UE rate and implement initiatives to target a goal less than 0.5 UEs/100 ventilator days. METHODS We utilized the Model for Improvement. Key stakeholders included neonatal providers, nurses, and respiratory therapists. We focused on the creation of an airway bundle that addressed securement methods, communication and education. RESULTS From October 2017 to January 2018, our baseline UE rate was 0.92 UEs/100 ventilator days. Subsequent to the implementation of an airway bundle with high compliance, we observed a significant change in the centerline (0.45 to 0.02 UEs/100 ventilator days) during the spring of 2021, followed by a period of 480 days with no UEs. CONCLUSION In a unit where UEs were infrequent events, high compliance with an airway bundle led to a significantly sustained decrease in our UE rates.

Xue L, Han D. Comparison of Two Anesthetic Regimens on Extubation Time and Postoperative Recovery in Children Undergoing Ambulatory Adenoidectomy: A Retrospective Study. J Perianesth Nurs 2024; 39:66-72. [PMID: 37768264 DOI: 10.1016/j.jopan.2023.06.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 06/05/2023] [Accepted: 06/09/2023] [Indexed: 09/29/2023]
Abstract
PURPOSE This aim of this study was to compare two anesthetic regimens in terms of extubation time and postoperative recovery in children undergoing ambulatory adenoidectomy. DESIGN A retrospective cohort study with propensity score matching. METHODS The medical charts of 452 children aged between 3 and 8 years undergoing ambulatory adenoidectomy were retrieved for analysis, of which 438 were eligible to participate in this study. A majority (n = 327) were children exposed to a conventional propofol-pronounced general anesthetic regimen (high-dose propofol plus low-dose remifentanil, labeled as group P), while n = 111 were administered a modified remifentanil-pronounced anesthetic regimen (low-dose propofol plus high-dose remifentanil, namely group R). Propensity score matching was employed to adjust for confounders, resulting in 69 matched patients in each group. The primary endpoint of this study was extubation time. The secondary endpoints were total intraoperative fluid volume, length of stay in the postanesthesia care unit (PACU), postoperative pain rating, the incidence of emergence agitation, nausea and vomiting, as well as the level of consciousness (fully awake or waking by gentle patting) when transferred out of PACU, and any major complications (wound bleeding, reintubation, readmission, and overnight stay). FINDINGS No major complications were observed in both groups. Compared to group P, group R had significantly shorter extubation time (8.2 ± 1.4 minutes vs 13.3 ± 2.4 minutes, P < .001), shorter length of stay in the PACU (14.1 ± 3.1 minutes vs 20.2 ± 3.4 minutes, P < .001), and a higher proportion of cases being fully awake when transferred out of the PACU (91% vs 46%, P < .001). Lastly, the pain rating, frequency of oropharyngeal airway usage, incidence of emergence agitation, and nausea and vomiting were comparable between the two groups (P > .05 for all). CONCLUSIONS Remifentanil-pronounced anesthesia was superior to propofol-pronounced anesthesia in children undergoing ambulatory adenoidectomy, given that the former was associated with a faster recovery time from anesthesia without jeopardizing patient safety.

Abstract
PURPOSE Immediate extubation (IE) following liver transplantation (LT) is increasingly common in adult patients. This study reviews our center's experience with IE in children following LT to determine characteristics predictive of successful IE and its effects on post-operative outcomes. METHODS We performed a retrospective chart review of all patients who underwent LT at our institution between January 2005 and November 2022. Patients with concomitant lung transplants and chronic ventilator requirements were excluded. RESULTS Overall, 235 patients met study criteria. IE was achieved in 164 (69.8%) patients across all diagnoses and graft types. Of IE patients, only two required re-intubation within 3 days post-transplant. IE patients exhibited significantly shorter ICU (2 [1, 3 IQR] vs. 4 [2, 4 IQR] days, p < .001) and hospital lengths of stay (17 [12, 24 IQR] vs. 22 [14, 42 IQR] days, p = .001). Pre-transplant ICU requirement, high PELD/MELD score, intraoperative transfusion, cold ischemia time, and pressor requirements were risk factors against IE. There was no association between IE and recipient age or weight. The proportion of patients undergoing IE post-transplant increased significantly over time from 2005 to 2022 (p < .001), underscoring the role of clinical experience and transplant team learning curve. CONCLUSION Spanning 18 years and 235 patients, we report the largest cohort of children undergoing IE following LT. Our findings support that IE is safe across ages and clinical scenarios. As our center gained experience, the rate of IE increased from 40% to 83%. These trends were associated with lower ICU and LOS, the benefits of which include earlier patient mobility and improved resource utilization.

Abstract
PURPOSE This study aimed to determine the best strategy to achieve fast and safe extubation. METHODS This multicenter trial randomized patients with primary respiratory failure and low-to-intermediate risk for extubation failure with planned high-flow nasal cannula (HFNC) preventive therapy. It included four groups: (1) conservative screening with ratio of partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2) ≥ 150 and positive end-expiratory pressure (PEEP) ≤ 8 cmH2O plus conservative spontaneous breathing trial (SBT) with pressure support 5 cmH2O + PEEP 0 cmH2O); (2) screening with ratio of partial pressure of arterial oxygen (PaO2) to fraction of inspired oxygen (FiO2) ≥ 150 and PEEP ≤ 8 plus aggressive SBT with pressure support 8 + PEEP 5; (3) aggressive screening with PaO2/FiO2 > 180 and PEEP 10 maintained until the SBT with pressure support 8 + PEEP 5; (4) screening with PaO2/FiO2 > 180 and PEEP 10 maintained until the SBT with pressure support 5 + PEEP 0. Primary outcomes were time-to-extubation and simple weaning rate. Secondary outcomes included reintubation within 7 days after extubation. RESULTS Randomization to the aggressive-aggressive group was discontinued at the interim analysis for safety reasons. Thus, 884 patients who underwent at least 1 SBT were analyzed (conservative-conservative group, n = 256; conservative-aggressive group, n = 267; aggressive-conservative group, n = 261; aggressive-aggressive, n = 100). Median time to extubation was lower in the groups with aggressive screening (p < 0.001). Simple weaning rates were 45.7%, 76.78% (205 patients), 71.65%, and 91% (p < 0.001), respectively. Reintubation rates did not differ significantly (p = 0.431). CONCLUSION Among patients at low or intermediate risk for extubation failure with planned HFNC, combining aggressive screening with preventive PEEP and a conservative SBT reduced the time to extubation without increasing the reintubation rate.

Abstract
The main clinical research advances of critical care in 2023 includes: new trials of Chinese herbal medicine, hydroxocobalamin (vitamin B12), methylene blue as well glucocorticoids have shown the potential to improve outcomes of patients with sepsis and septic shock; international committees launched new global definition and managing recommendations for acute respiratory distress syndrome (ARDS). Besides, a cluster of new evidences has emerged in many aspects as following: fluid control strategy in sepsis (restrictive/liberative), antibiotic infusion strategy (continuous/intermittent), oxygen-saturation targets for mechanical ventilation (conservative/liberative), blood pressure targets after resuscitation from out-of-hospital cardiac arrest (hypotension/hypertension), blood pressure targets after successful stroke thrombectomy (intensive/conventional), and nutritional support strategies (low protein-calories/conventional protein-calories, fasting/persistent feeding before extubation). Thus, given above progress, carrying out high -quality domestic multi-center clinical registration researches, constructing shareable standardized databases, as well raising public awareness of sepsis, should be the essential steps to improve our level of intensive care medicine.

Abstract
OBJECTIVE To identify variables associated with extubation success in extremely preterm neonates extubated from invasive volume-targeted ventilation. STUDY DESIGN We retrospectively evaluated 84 neonates ≤28 weeks' gestational age, on their first elective extubation. The primary outcome of successful extubation was defined as non-reintubation within seven days. We used multivariate logistic regression analysis. RESULTS We identified 58 (69%) neonates (mean gestational age of 26.5 ± 1.4 weeks, birthweight 921 ± 217 g) who met the primary outcome. Female sex (OR 1.15, 95% CI 1.01-9.10), higher pre-extubation weight (OR 1.29, 95% CI 1.05-1.59), and pH (OR 2.54, 95% CI 1.54-4.19), and lower pre-extubation mean airway pressure (MAP) (OR 0.49, 95% CI 0.33-0.73) were associated with successful extubation. CONCLUSIONS In preterm neonates, female sex, higher pre-extubation weight and pH, and lower pre-extubation MAP were predictors of successful extubation from volume-targeted ventilation. Evaluation of these variables will likely assist clinicians in selecting the optimal time for extubation in such vulnerable neonates.

Abstract
Delirium is common in the emergency department, and once it develops, there is a risk of self-extubation of drains and tubes, so it is critical to predict delirium before it occurs. Machine learning was used to create two prediction models in this study: one for predicting the occurrence of delirium and one for predicting self-extubation after delirium. Each model showed high discriminative performance, indicating the possibility of selecting high-risk cases. Visualization of predictors using Shapley additive explanation (SHAP), a machine learning interpretability method, showed that the predictors of delirium were different from those of self-extubation after delirium. Data-driven decisions, rather than empirical decisions, on whether or not to use physical restraints or other actions that cause patient suffering will result in improved value in medical care.
