ABSTRACT
OBJECTIVE: To compare the frequency of respiratory complications encountered in two different positions used for extubation i.e. conventional recovery position versus the modified recovery position (recovery position with 10-degree left tilt and head-down). STUDY DESIGN: Comparative study. Place and Duration of the Study: Department of Anaesthesia, Combine Military Hospital, Kohat, Pakistan, from April 2022 to March 2023. METHODOLOGY: Two hundred patients scheduled for elective nose and throat surgeries were equally divided into two groups (Group C and Group M). Patients with history of bronchial asthma, chronic obstructive pulmonary disease (COPD), recent respiratory infection, and gastro-oesophageal reflux disease (GERD) were excluded from this study. Patients with more than two intubation attempts were also excluded. Group C patients were extubated in a conventional left lateral recovery position, whereas Group M patients were extubated in a modified recovery position with patient in a left lateral position with 10-degree head-down and 10-degree left tilt. All patients were observed for persistent coughing (coughing that lasted for at least 2 minutes after extubation), breath holding for 20 seconds or more, desaturation (oxygen saturation less than 90%), laryngospasm, need for reintubation, vomiting, and regurgitation. RESULTS: Frequency of airway complications was significantly higher in Group C as compared to Group M. In Group C, 18 (18%) out of hundred patients had complications compared to 6 (6%) patients only in Group M (p = 0.009). CONCLUSION: Extubation in a modified recovery position is associated with reduced frequency of airway complications as compared to the conventional recovery position. KEY WORDS: Airway complications, Extubation, Cough, Laryngospasm, Recovery position.

BACKGROUND: Preterm infants often require non-invasive breathing support while their lungs and control of respiration are still developing. Non-invasive neurally adjusted ventilatory assist (NIV-NAVA) is an emerging technology that allows infants to breathe spontaneously while receiving support breaths proportional to their effort. This study describes the first Australian Neonatal Intensive Care Unit (NICU) experience of NIV-NAVA. METHODS: Retrospective cohort study of infants admitted to a major tertiary NICU between October 2017 and April 2021 supported with NIV-NAVA. Infants were divided into three groups based on the indication to initiate NIV-NAVA (post-extubation; apnoea; escalation). Successful application of NIV-NAVA was based on the need for re-intubation within 48 h of application. RESULTS: There were 169 NIV-NAVA episodes in 122 infants (82 post-extubation; 21 apnoea; 66 escalation). The median (range) gestational age at birth was 25 + 5 weeks (23 + 1 to 43 + 3 weeks) and median (range) birthweight was 963 g (365-4320 g). At NIV-NAVA application, mean (SD) age was 17 days (18.2), and median (range) weight was 850 g (501-4310 g). Infants did not require intubation within 48 h in 145/169 (85.2%) episodes [72/82 (87.8%) extubation; 21/21 (100%) apnoea; 52/66 (78.8%) escalation). CONCLUSION: NIV-NAVA was successfully integrated for the three main indications (escalation; post-extubation; apnoea). Prospective clinical trials are still required to establish its effectiveness versus other modes of non-invasive support.

To observe of the effect of electrical stimulation at the back-shu acupoint with extrinsic diaphragmatic pacing (EDP) mode on respiratory function and extubation success rate in tracheostomized stroke patients. A total of 200 patients who underwent tracheostomy after a stroke from January 2022 to February 2023 were included in this study. They were divided into 2 groups based on whether electroacupuncture was used: the EDPâ +â electroacupuncture group and the EDP group. We assessed the differences in cough reflex scores and clinical lung infection scores between the 2 groups, and measured levels of blood gas analysis indicators, diaphragmatic function, lung function, maximum inspiratory pressure, and maximum expiratory pressure in both groups. The total effective rate in the EDPâ +â electroacupuncture group was 91.00% (91/100), which was higher than the EDP group's 80.00% (80/100) (Pâ <â .05). After treatment, both groups showed a decrease in clinical lung infection scores and cough reflex scores compared to before treatment, with the EDPâ +â electroacupuncture group having lower scores than the EDP group (Pâ <â .05). After treatment, the pH value, arterial oxygen pressure, and oxygenation index all increased compared to before treatment, with the EDPâ +â electroacupuncture group showing higher values than the EDP group (Pâ <â .05). After treatment, both groups showed a decrease in arterial carbon dioxide pressure compared to before treatment, with the EDPâ +â electroacupuncture group having lower PaCO2 levels than the EDP group (Pâ <â .05). After treatment, both groups showed an increase in forced vital capacity as a percentage of predicted value (FVC%), diaphragm thickness, diaphragm mobility, maximum inspiratory pressure, maximum expiratory pressure, forced expiratory volume in the first second as a percentage of predicted value (FEV1%), and diaphragm contraction speed compared to before treatment. Additionally, the EDPâ +â electroacupuncture group had higher values in these parameters compared to the EDP group (Pâ <â .05). The EDPâ +â electroacupuncture group had a shorter average extubation time and a higher extubation success rate compared to the EDP group (Pâ <â .05). The combination of EDP mode and electroacupuncture at the back-shu acupoint appears to be effective in improving lung function and diaphragmatic function in tracheostomized stroke patients. It also leads to a shorter extubation time and higher extubation success rates.

PURPOSE: Awake extubation and deep extubation are commonly used anesthesia techniques. In this study, the safety of propofol-assisted deep extubation in the dental treatment of children was assessed. MATERIALS AND METHODS: Children with severe caries who received dental treatment under general anesthesia and deep extubation between January 2017 and June 2023 were included in this study. Data were collected on the following variables: details and time of anesthesia, perioperative vital signs, and incidence of postoperative complications. The incidence of laryngeal spasm (LS) was considered to be the primary observation indicator. RESULTS: The perioperative data obtained from 195 children undergoing dental treatment was reviewed. The median age was 4.2 years (range: 2.3 to 9.6 years), and the average duration of anesthesia was 2.56 h (range 1 to 4.5 h). During intubation with a videoscope, purulent mucus was found in the pharyngeal cavity of seven children (3.6%); LS occurred in five of them (2.6%), and one child developed a fever (T = 37.8 °C) after discharge. Five children (2.6%) experienced emergence agitation (EA) in the recovery room. Also, 13 children (6.7%) experienced epistaxis; 10 had a mild experience and three had a moderate experience. No cases of airway obstruction (AO) and hypoxemia were recorded. The time to open eyes (TOE) was 16.3 ± 7.2 min. The incidence rate of complications was 23/195 (11.8%). Emergency tracheal reintubation was not required. Patients with mild upper respiratory tract infections showed a significantly higher incidence of complications (P < 0.001). CONCLUSIONS: Propofol-assisted deep extubation is a suitable technique that can be used for pediatric patients who exhibited non-cooperation in the outpatient setting. Epistaxis represents the most frequently encountered complication. Preoperative upper respiratory tract infection significantly increases the risk of complications. The occurrence of EA was notably lower than reported in other studies.

PURPOSE: To report two-year survival after scheduled extubation in patients with pneumonia or acute respiratory distress syndrome (ARDS). METHODS: This was a prospective observational study performed in a respiratory ICU of a teaching hospital. Pneumonia or ARDS patients who successfully completed a spontaneous breathing trial were enrolled. Data were collected before extubation. Patients were followed up to two years by phone every 3 months. RESULTS: A total of 230 patients were enrolled in final analysis. One-, 3-, 6-, 12-, and 24-month survival was 77.4%, 63.8%, 61.3%, 57.8%, and 47.8%, respectively. Cox regression shows that Charlson comorbidity index (hazard ratio: 1.20, 95% confidence interval: 1.10-1.32), APACHE II score before extubation (1.11, 1.05-1.17), cough peak flow before extubation (0.993, 0.986-0.999), and extubation failure (3.96, 2.51-6.24) were associated with two-year mortality. To predict death within two years, the area under the curve of receiver operating characteristic was 0.79 tested by Charlson comorbidity index, 0.75 tested by APACHE II score, and 0.75 tested by cough peak flow. Two-year survival was 31% and 77% in patients with Charlson comorbidity index ≥ 1 and < 1, 28% and 62% in patients with APACHE II score ≥ 12 and < 12, and 64% and 17% in patients with cough peak flow > 58 and ≤ 58 L/min, respectively. CONCLUSIONS: Comorbidity, disease severity, weak cough and extubation failure were associated with increased two-year mortality in pneumonia or ARDS patients who experienced scheduled extubation. It provides objective information to caregivers to improve decision-making process during hospitalization and post discharge.

PURPOSE: We aimed to evaluate the ability of the peripheral perfusion index (PPI) to predict reintubation of critically ill surgical patients. METHODS: This prospective observational study included mechanically ventilated adults who were extubated after a successful spontaneous breathing trial (SBT). The patients were followed up for the next 48 h for the need for reintubation. The heart rate, systolic blood pressure, respiratory rate, peripheral arterial oxygen saturation (SpO2), and PPI were measured before-, at the end of SBT, 1 and 2 h postextubation. The primary outcome was the ability of PPI 1 h postextubation to predict reintubation using area under the receiver operating characteristic curve (AUC) analysis. Univariate and multivariate analyses were performed to identify predictors for reintubation. RESULTS: Data from 62 patients were analysed. Reintubation occurred in 12/62 (19%) of the patients. Reintubated patients had higher heart rate and respiratory rate; and lower SpO2 and PPI than successfully weaned patients. The AUC (95%confidence interval) for the ability of PPI at 1 h postextubation to predict reintubation was 0.82 (0.71-0.91) with a negative predictive value of 97%, at a cutoff value of ≤ 2.5. Low PPI and high respiratory rate were the independent predictors for reintubation. CONCLUSION: PPI early after extubation is a useful tool for prediction of reintubation. Low PPI is an independent risk factor for reintubation. A PPI > 2.5, one hour after extubation can confirm successful extubation.

BACKGROUND: Surfactant is a well-established therapy for preterm neonates affected by respiratory distress syndrome (RDS). The goals of different methods of surfactant administration are to reduce the duration of mechanical ventilation and the severity of bronchopulmonary dysplasia (BPD); however, the optimal administration method remains unknown. This study compares the effectiveness of the INtubate-RECruit-SURfactant-Extubate (IN-REC-SUR-E) technique with the less-invasive surfactant administration (LISA) technique, in increasing BPD-free survival of preterm infants. This is an international unblinded multicenter randomized controlled study in which preterm infants will be randomized into two groups to receive IN-REC-SUR-E or LISA surfactant administration. METHODS: In this study, 382 infants born at 24+0-27+6 weeks' gestation, not intubated in the delivery room and failing nasal continuous positive airway pressure (nCPAP) or nasal intermittent positive pressure ventilation (NIPPV) during the first 24 h of life, will be randomized 1:1 to receive IN-REC-SUR-E or LISA surfactant administration. The primary outcome is a composite outcome of death or BPD at 36 weeks' postmenstrual age. The secondary outcomes are BPD at 36 weeks' postmenstrual age; death; pulse oximetry/fraction of inspired oxygen; severe intraventricular hemorrhage; pneumothorax; duration of respiratory support and oxygen therapy; pulmonary hemorrhage; patent ductus arteriosus undergoing treatment; percentage of infants receiving more doses of surfactant; periventricular leukomalacia, severe retinopathy of prematurity, necrotizing enterocolitis, sepsis; total in-hospital stay; systemic postnatal steroids; neurodevelopmental outcomes; and respiratory function testing at 24 months of age. Randomization will be centrally provided using both stratification and permuted blocks with random block sizes and block order. Stratification factors will include center and gestational age (24+0 to 25+6 weeks or 26+0 to 27+6 weeks). Analyses will be conducted in both intention-to-treat and per-protocol populations, utilizing a log-binomial regression model that corrects for stratification factors to estimate the adjusted relative risk (RR). DISCUSSION: This trial is designed to provide robust data on the best method of surfactant administration in spontaneously breathing preterm infants born at 24+0-27+6 weeks' gestation affected by RDS and failing nCPAP or NIPPV during the first 24 h of life, comparing IN-REC-SUR-E to LISA technique, in increasing BPD-free survival at 36 weeks' postmenstrual age of life.

BACKGROUND: In standard weaning from mechanical ventilation, a successful spontaneous breathing test (SBT) consisting of 30 min 8 cmH2O pressure-support ventilation (PSV8) without positive end-expiratory pressure (PEEP) is followed by extubation with continuous suctioning; however, these practices might promote derecruitment. Evidence supports the feasibility and safety of extubation without suctioning. Ultrasound can assess lung aeration and respiratory muscles. We hypothesize that weaning aiming to preserve lung volume can yield higher rates of successful extubation. METHODS: This multicenter superiority trial will randomly assign eligible patients to receive either standard weaning [SBT: 30-min PSV8 without PEEP followed by extubation with continuous suctioning] or lung-volume-preservation weaning [SBT: 30-min PSV8 + 5 cmH2O PEEP followed by extubation with positive pressure without suctioning]. We will compare the rates of successful extubation and reintubation, ICU and hospital stays, and ultrasound measurements of the volume of aerated lung (modified lung ultrasound score), diaphragm and intercostal muscle thickness, and thickening fraction before and after successful or failed SBT. Patients will be followed for 90 days after randomization. DISCUSSION: We aim to recruit a large sample of representative patients (N = 1600). Our study cannot elucidate the specific effects of PEEP during SBT and of positive pressure during extubation; the results will show the joint effects derived from the synergy of these two factors. Although universal ultrasound monitoring of lungs, diaphragm, and intercostal muscles throughout weaning is unfeasible, if derecruitment is a major cause of weaning failure, ultrasound may help clinicians decide about extubation in high-risk and borderline patients. TRIAL REGISTRATION: The Research Ethics Committee (CEIm) of the Fundació Unió Catalana d'Hospitals approved the study (CEI 22/67 and 23/26). Registered at ClinicalTrials.gov in August 2023.

AIM: To develop a decision-support tool for predicting extubation failure (EF) in neonates with bronchopulmonary dysplasia (BPD) using a set of machine-learning algorithms. METHODS: A dataset of 284 BPD neonates on mechanical ventilation was used to develop predictive models via machine-learning algorithms, including extreme gradient boosting (XGBoost), random forest, support vector machine, naïve Bayes, logistic regression, and k-nearest neighbor. The top three models were assessed by the area under the receiver operating characteristic curve (AUC), and their performance was tested by decision curve analysis (DCA). Confusion matrix was used to show the high performance of the best model. The importance matrix plot and SHapley Additive exPlanations values were calculated to evaluate the feature importance and visualize the results. The nomogram and clinical impact curves were used to validate the final model. RESULTS: According to the AUC values and DCA results, the XGboost model performed best (AUC = 0.873, sensitivity = 0.896, specificity = 0.838). The nomogram and clinical impact curve verified that the XGBoost model possessed a significant predictive value. The following were predictive factors for EF: pO2, hemoglobin, mechanical ventilation (MV) rate, pH, Apgar score at 5 min, FiO2, C-reactive protein, Apgar score at 1 min, red blood cell count, PIP, gestational age, highest FiO2 at the first 24 h, heart rate, birth weight, pCO2. Further, pO2, hemoglobin, and MV rate were the three most important factors for predicting EF. CONCLUSIONS: The present study indicated that the XGBoost model was significant in predicting EF in BPD neonates with mechanical ventilation, which is helpful in determining the right extubation time among neonates with BPD to reduce the occurrence of complications.

BACKGROUND AND OBJECTIVE: Early and smooth extubation following anesthesia is an important concern in patients undergoing transsphenoidal pituitary surgery to permit early neurological evaluation and prevent complications. The aim was to compare the RESPONSE FIRST and REVERSAL FIRST techniques for quality of extubation (QOE) in patients undergoing endoscopic transsphenoidal pituitary surgery. METHODS: Fifty-six patients aged 18-60 years, with American Society of Anesthesiologists Physical Statuses I-II, and undergoing transsphenoidal surgery for pituitary tumors were randomized into either the RESPONSE FIRST group, in which neuromuscular reversal was given following the patient's response to oral commands, or the REVERSAL FIRST group, in which reversal of neuromuscular blockade (NMB) was given at the return of spontaneous respiration. QOE was the primary outcome. Hemodynamic response, jugular venous oxygen saturation (SjVO2), time to extubation, and awareness during emergence were assessed as secondary outcomes. RESULTS: The QOE in the RESPONSE FIRST group was significantly better than the REVERSAL FIRST group (mean (interquartile range (IQR)), 18 (17-19) vs 14 (12-14.75), P < 0.001). Heart rate (HR) and mean arterial pressure (MAP) were better in the RESPONSE FIRST group when compared to the REVERSAL FIRST group at the time of extubation, at 5 minutes, and 15 minutes following extubation (P < 0.05). SjVO2values were higher in the REVERSAL FIRST group as compared to the RESPONSE FIRST group during extubation and at 5 minutes after extubation (P < 0.01). There was no significant difference in the time to extubation between the groups (P = 0.73). CONCLUSION: The RESPONSE FIRST technique is associated with better QOE and preservation of systemic and cerebral hemodynamics during extubation in patients undergoing transsphenoidal pituitary surgery when compared to the REVERSAL FIRST technique.

BACKGROUND: Post-operative sore throat is the common complaint and uncomfortable side effect in patients receiving general anesthesia with endotracheal intubation. Drugs with analgesic and anti-inflammatory properties, like steroids and local anesthetics, are the best options for postoperative sore throat prophylaxis. Therefore, this study aimed to compare the effects of intravenous lidocaine and dexamethasone in reducing postoperative sore throat following endotracheal extubation at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, from January 1 to March 30, 2023 G.C. METHODS: A prospective cohort study was carried out at Tikur Anbessa Specialized Hospital. Data from 50 patients in the lidocaine (1.5 mg/kg), 50 in the dexamethasone (8 mg), and 49 in the control groups were analyzed. The data were collected using observation based on structured questionnaires. A systematic random sampling technique was applied to select respondents. The data were entered into EpiData version 4.6.0.6 and transferred to STATA version 17 statistical software for analysis. A comparison of continuous data among the groups were performed using a one-way ANOVA test for parametric data. The Kruskal-Wallis rank test was used for non-parametric data. Associations between variables were tested using chi-squared test, Fisher's exact test, and binary logistic regression. Bivariable and multivariable logistic regression was used to determine degree of association. RESULTS: The incidence of POST was 40%, 32%, and 57.1% in the lidocaine, dexamethasone, and control groups, respectively (P = .0356). Dexamethasone reduced the incidence of POST during the first 24 h (AOR: 0.374, 95% CI: 0.149-0.939). However, no difference was observed in the severity of POST at 3 h (p = 0.130), 6 h (p = 0.096), 12 h (p = 0.313), and 24 h (p = 0.525) of the post-extubation period among the three groups. IV lidocaine did not effectively reduce the incidence and severity of postoperative sore throat at different time intervals. CONCLUSION AND RECOMMENDATION: Intravenous dexamethasone is more effective than intravenous lidocaine in reducing the incidence of postoperative sore throat among the groups. Based on these findings, intravenous dexamethasone is recommended to decrease the incidence of postoperative sore throat.

INTRODUCTION: Noninvasive High-Frequency Oscillatory Ventilation (NHFOV) is increasingly being adopted to reduce the need for invasive ventilation after extubation. OBJECTIVES: To evaluate the benefits and harms of NHFOV as post-extubation respiratory support in newborns compared to other non-invasive respiratory support modes. MATERIAL & METHODS: We included randomized controlled trials comparing NHFOV with other non-invasive modes post-extubation in newborns. Data sources were MEDLINE (via Pubmed), Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, WHO international clinical trials registry platform and Clinical Trial Registry, forward and backward citation search. Methodological quality of studies was assessed by Cochrane's Risk of Bias tool 1.0. RESULTS: This systematic review included 21 studies and 3294 participants, the majority of whom were preterm. NHFOV compared to nasal continuous positive airway pressure (NCPAP) reduced reintubation within seven days (RR 0.34, 95% CI 0.22 to 0.53) after extubation. It also reduced extubation failure (RR 0.39, 95% CI 0.30 to 0.51) and reintubation within 72 hrs (RR 0.40, 95% CI 0.31 to 0.53), bronchopulmonary dysplasia (RR 0.59, 95% CI 0.37 to 0.94) and pulmonary air leak (RR 0.46, 95% CI 0.27 to 0.79) compared to NCPAP. The rate of reintubation within seven days (RR 0.62, 95% CI 0.18 to 2.14) was similar whereas extubation failure (RR 0.65, 95% CI 0.50 to 0.83) and reintubation (RR 0.68, 95% CI 0.52 to 0.89) within 72 hrs were lower in NHFOV group compared to nasal intermittent positive pressure ventilation. There was no effect on other outcomes. Overall quality of the evidence was low to very low in both comparisons. CONCLUSIONS: NHFOV may reduce the rate of reintubation and extubation failure post-extubation without increasing complications. Majority of the trials were exclusively done in preterm neonates. Further research with high methodological quality is warranted.

Major head and neck surgery poses a threat to perioperative airway patency. Adverse airway events are associated with significant morbidity, potentially leading to hypoxic brain injury and even death. Following a review of the literature, recommendations regarding airway management in head and neck surgery were developed with multicenter, multidisciplinary agreement among all Irish head and neck units. Immediate extubation is appropriate in many cases where there is a low risk of adverse airway events. Where a prolonged definitive airway is required, elective tracheostomy provides increased airway security postoperatively while delayed extubation may be appropriate in select cases to reduce postoperative morbidity. Local institutional protocols should be developed to care for a tracheostomy once inserted. We provide guidance on decision making surrounding airway management at time of head and neck surgery. All decisions should be agreed between the operating, anesthetic, and critical care teams.

Objective: The aims of this study was to analyse fibreoptic endoscopic evaluation of swallowing (FEES) findings in tube-fed patients with coronavirus disease 2019 (COVID-19). Methods: Seventeen patients who had been intubated during intensive care unit (ICU) stay were enrolled. Pooling of secretions, dysphagia phenotype, penetration/aspiration and residue after swallow were assessed through FEES. The Functional Oral Intake Scale (FOIS) scores were also collected. Patients with significant swallowing impairment were evaluated again after 2 weeks. Results: All patients were tube-fed at enrollment. According to the FEES results, 7 started total oral feeding with at least one consistency. The more common dysphagia phenotypes were propulsive deficit and delayed pharyngeal phase. Pooling of secretions, penetration/aspiration, and residue after swallow were frequently documented. A significant improvement in FOIS scores was found during the second FEES examination. Conclusions: Swallowing impairment in patients with severe COVID-19 after discharge from the ICU is characterised by propulsive deficit and delayed pharyngeal phase. Most of these patients required feeding restrictions even if feeding abilities seem to improve over time.

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.

BACKGROUND: Recent meta-analyses and randomized studies have shown that among patients with acute ischemic stroke undergoing endovascular thrombectomy, general anesthesia with mechanical ventilation is associated with better functional status compared to local anesthesia and sedation, and they recommend its use. But once the procedure is completed, when is the optimal moment for extubation? Currently, there are no guidelines recommending the optimal moment for extubation. Prolonged mechanical ventilation time could potentially be linked to increased complications such as pneumonia or disturbances in cerebral blood flow due to the vasodilatation produced by most anesthetic drugs. However, premature extubation in a patient who has suffered a stroke could led to complications such as agitation, disorientation, abolished reflexes, sudden fluctuations in blood pressure, alterations in cerebral blood flow, respiratory distress, bronchial aspiration, and the need for reintubation. We therefore designed a randomized study hypothesizing that early compared with delayed extubation is associated with a better functional outcome 3 months after endovascular thrombectomy treatment under general anesthesia for acute ischemic stroke. METHODS: This investigator-initiated, single-center, prospective, parallel, evaluated blinded, superiority, randomized controlled trial will include 178 patients with a proximal occlusion of the anterior circulation treated with successful endovascular thrombectomy (TICI 2b-3) under general anesthesia. Patients will be randomly allocated to receive early (< 6 h) or delayed (6-12 h) extubation after the procedure. The primary outcome measure is functional independence (mRS of 0-2) at 90 days, measured with the modified Rankin Score (mRS), ranging from 0 (no symptoms) to 6 (death). DISCUSSION: This will be the first trial to compare the effect of mechanical ventilation duration (early vs delayed extubation) after satisfactory endovascular thrombectomy for acute ischemic stroke under general anesthesia. TRIAL REGISTRATION: The study protocol was approved April 11, 2023, by the by the Santiago-Lugo Research Ethics Committee (CEI-SL), number 2023/127, and was registered into the clinicaltrials.gov clinical trials registry with No. NCT05847309. Informed consent is required. Participant recruitment begins on April 18, 2023. The results will be submitted for publication in a peer-reviewed journal and presented at one or more scientific conferences.

OBJECTIVE: To determine whether implementation of an education-based intervention can sustainably improve upstream and downstream outcomes in intubated patients in a pediatric intensive care unit (PICU) in a low-resource country. DESIGN: Quality improvement study comparing airway-related morbidity in two previously studied patient cohorts pre-intervention (Epoch 1) and immediately post-intervention (Epoch 2) with a third cohort thirty-six months post-intervention (Epoch 3). SETTING: PICU of the largest public children's hospital in El Salvador. PATIENTS: 147 patients under 18 years requiring intubation and mechanical ventilation (MV) met inclusion criteria in the long-term follow-up period and were consecutively sampled without exclusion (Epoch 3) (compared to 98 previously studied patients in the short-term follow-up period (Epoch 2)). INTERVENTION: A low-cost, education-based intervention to close knowledge gaps, improve communication among PICU doctors, nurses, and respiratory therapists, and optimize patient outcomes. MEASUREMENTS AND MAIN RESULTS: The primary outcome measure was change in unplanned extubation (UE) between Epochs 2 and 3. Other outcomes included use of cuffed endotracheal tubes (ETT), rate of elective ETT change and days of MV. The 17 % decrease in UE previously reported for Epoch 2 was sustained in Epoch 3. There was a statistically significant increase in use of cuffed ETT from 35.7 % in Epoch 2-55.1 % in Epoch 3 (p = 0.003, z-score -2.99). There was also a statistically significant mean difference in rate of elective ETT change per 100 MV days from Epoch 2 to Epoch 3 of 1.7 (p = 0.007; 95 % CI 0.15-0.84). There was no change in MV days from Epoch 2 to Epoch 3 (p-value 0.764; 95 % CI -1.48-2.02). Beyond these quantifiable results, many unanticipated practice changes were observed three years after the initial intervention. CONCLUSIONS: Sustained improvement in upstream and downstream outcomes (UE, cuffed ETT use, elective ETT change) for intubated patients in a low-resource PICU were observed three years after a low-cost, low-touch, education-based intervention.

ABSTRACT: BACKGROUND: Delirium is a common neurological complication in patients admitted to the intensive care unit (ICU) after moderate to severe traumatic brain injury (TBI). Although current clinical guidelines prioritize delirium prevention, no specific tool is tailored to detect early signs of delirium in TBI patients. This preliminary 2-phase observational study investigated the correlation between the pupillary light reflex (PLR), measured with a pupillometer during mechanical ventilation, and the development of postextubation delirium in TBI patients. METHODS: A convenience sample of 26 adults with moderate to severe TBI under mechanical ventilation was recruited during their ICU stay. In phase I, PLR measurements were performed in the first 3 days of ICU admission using automated infrared pupillometry. In phase II, 2 raters independently extracted delirium data in the 72 hours post extubation period from medical records. Delirium was confirmed with a documented medical diagnosis. Point-biserial correlations ( rpb ) were used to examine the association between PLR scores and the presence of postextubation delirium. Student t tests were also performed to compare mean PLR scores between patients with and without delirium. RESULTS: Ten TBI patients (38%) were diagnosed with postextubation delirium, whereas 16 (62%) were not. Significant correlations between delirium and 2 PLR variables were found: pupil constriction percentage ( rpb (24) = -0.526, P = .006) and constriction velocity ( rpb (24) = -0.485, P = .012). The t test also revealed a significant difference in constriction percentage and velocity scores between TBI patients with and without delirium ( P ≤ .01). CONCLUSION: Our findings suggest that the use of pupillometry in the first 3 days of mechanical ventilation during an ICU stay may help identify TBI patients at risk for delirium after extubation. Although further research is necessary to support its validity, this technological tool may enable ICU nurses to better screen TBI patients for delirium and prevent its development.

OBJECTIVE: This study was performed to explore the predictive value of the diaphragmatic thickness fraction (DTF) combined with the integrated pulmonary index (IPI) for the extubation outcome in patients with severe acute pancreatitis (SAP). METHODS: This prospective study involved 93 patients diagnosed with SAP and treated with mechanical ventilation in our hospital from October 2020 to September 2023. The patients were divided into a successful extubation group (61 patients) and an extubation failure group (32 patients) based on the extubation outcomes. The predictive value of the DTF, IPI, and their combination for extubation failure was analyzed. RESULTS: The DTF and IPI were independent risk factors for extubation failure in patients with SAP undergoing mechanical ventilation. In addition, the combination of the DTF and IPI showed predictive value for extubation failure in these patients. CONCLUSION: The DTF and IPI hold predictive value for extubation failure in patients with SAP undergoing mechanical ventilation, and their combined use may improve the predictive efficiency.
