RESUMO
STUDY DESIGN: Retrospective cohort study. OBJECTIVES: Investigate the risk factors for delayed extubation after posterior approach orthopedic surgery in patients with congenital scoliosis. METHODS: The clinical data of patients who received surgery for congenital scoliosis at the First Affiliated Hospital of Xinjiang Medical University between January 2021 and July 2023 have been gathered. Patients are categorized into the usual and the delayed extubation groups, depending on the duration of tracheal intubation after surgery. The study employs univariate and multivariate logistic regression models to examine the clinical characteristics of the two cohorts and discover potential risk factors linked to delayed extubation. In addition, a prediction model is created to visually depict the significance of each risk factor in terms of weight according to the nomogram. RESULTS: A total of 119 patients (74.8% females), with a median age of 15 years, are included. A total of 32 patients, accounting for 26.9% of the sample, encountered delayed extubation. Additionally, 13 patients (10.9%) suffered perioperative complications, with pneumonia being the most prevalent. The multivariate regression analysis revealed that the number of osteotomy segments, postoperative hematocrit, postoperative Interleukin-6 levels, and weight are predictive risk factors for delayed extubation. CONCLUSIONS: Postoperative hematocrit and Interleukin-6 level, weight, and number of osteotomy segments can serve as independent risk factors for predicting delayed extubation, with combined value to assist clinicians in evaluating the risk of delayed extubation of postoperative congenital scoliosis patients, improving the success rate of extubation, and reducing postoperative treatment time in the intensive care unit.
RESUMO
Spontaneous cerebellar hemorrhage (SCH) patients have a low success rate in extubation, but there are currently no guidelines establishing specifically for SCH patients extubation. The study included 68 SCH patients who received mechanical ventilation for more than 24 h, with 39 cases (57.3%) resulting in successful extubation. The multivariate analysis identified four factors significantly associated with extubation success: patient age under 66 years, an Intracerebral Hemorrhage (ICH) score less than 4 points, the presence of tissue shift, and a Glasgow Coma Scale (GCS) score (excluding language) above 6 points at extubation. By simplifying the prediction model, we obtained the Spontaneous Cerebellar Hemorrhage Extubation Success scoring system (SCHES-SCORE). Within the scoring system, 2 points were allocated for a GCS score (excluding language) above 6 at extubation, 1 point each for age under 66 years and an ICH score below 4, while tissue shift was assigned a negative point. A score of Grade A (SCHES-SCORE = 3-4) was found to correlate with a 92.9% success rate for extubation. The area under the receiver operating characteristic curve was 0.923 (95% CI, 0.863 to 0.983). Notably, successful extubation was significantly linked to reduced durations of mechanical ventilation, intensive care unit (ICU) stay, and total hospital stay. In conclusion, the scoring system developed for assessing extubation outcomes in SCH patients has the potential to enhance the rate of successful extubation and overall patient outcomes.
RESUMO
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.
RESUMO
Dyspnea, the subjective sensation of breathlessness, is a distressing and potentially traumatic symptom. Dyspnea associated with mechanical ventilation may contribute to intensive care unit (ICU) associated post-traumatic stress disorder and impaired quality of life. Dyspnea is both difficult to alleviate and a cause of significant distress to patients, their loved ones, and care providers People living with neuromuscular disease, such as amyotrophic lateral sclerosis (ALS) or myasthenia gravis (MG), often rely on a ventilator at late stages of illness due to complications of progressive respiratory muscle weakness and paralysis. When unable to wean from the ventilator, conversations turn towards goals of care and release from the ventilator for comfort and end of life (EOL). Patients with and without neuromuscular disease have high risk for dyspnea at EOL upon ventilator liberation. Although limited recommendations have been published specific to patients with ALS, no guidelines currently exist for the terminal liberation from mechanical ventilation in patients experiencing respiratory muscle insufficiency from a neuromuscular disease. Further research on this topic is needed, including creation of a protocol for ventilator release in patients with neuromuscular disease. The following case reports detail the dissimilar EOL experiences of two patients with different forms of neuromuscular disease.
RESUMO
BACKGROUND: The ratio (E/Ea) of mitral Doppler inflow velocity to annular tissue Doppler wave velocity by transthoracic echocardiography and diaphragmatic excursion (DE) by diaphragm ultrasound have been confirmed to predict extubation outcomes. However, few studies focused on the predicting value of E/Ea and DE at different positions during a spontaneous breathing trial (SBT), as well as the effects of â³E/Ea and â³DE (changes in E/Ea and DE during a SBT). METHODS: This study was a reanalysis of the data of 60 difficult-to-wean patients in a previous study published in 2017. All eligible participants were organized into respiratory failure (RF) group and extubation success (ES) group within 48 h after extubation, or re-intubation (RI) group and non-intubation (NI) group within 1 week after extubation. The risk factors for respiratory failure and re-intubation including E/Ea and â³E/Ea, DE and â³DE at different positions were analyzed by multivariate logistic regression, respectively. The receiver operating characteristic (ROC) curves of E/Ea (septal, lateral, average) and DE (right, left, average) were compared with each other, respectively. RESULTS: Of the 60 patients, 29 cases developed respiratory failure within 48 h, and 14 of those cases required re-intubation within 1 week. Multivariate logistic regression showed that E/Ea were all associated with respiratory failure, while only DE (right) and DE (average) after SBT were related to re-intubation. There were no statistic differences among the ROC curves of E/Ea at different positions, nor between the ROC curves of DE. No statistical differences were shown in â³E/Ea between RF and ES groups, while â³DE (average) was remarkably higher in NI group than that in RI group. However, multivariate logistic regression analysis showed that â³DE (average) was not associated with re-intubation. CONCLUSIONS: E/Ea at different positions during a SBT could predict postextubation respiratory failure with no statistical differences among them. Likewise, only DE (right) and DE (average) after SBT might predict re-intubation with no statistical differences between each other.

OBJECTIVES: To study the impact of high flow nasal cannula (HFNC) vs. conventional oxygen therapy (COT) (by simple nasal cannula) as respiratory support after extubation on the rates of post-extubation airway obstruction (PEAO) among mechanically ventilated critically ill children. METHODS: This open-label randomized controlled trial was conducted in pediatric intensive care unit (PICU) of a tertiary care teaching hospital in North India over a period of 7 mo (11 August 2021 to 10 March 2022). Children aged 3 mo to 12 y who required invasive mechanical ventilation for > 72 h and had passed spontaneous breathing trial (ready for extubation) were enrolled and randomized by computer generated block randomization to receive HFNC or COT after extubation. Primary outcome was rate of PEAO (assessed by modified Westley croup score, mWCS) within 48 h of extubation; and secondary outcomes were rate and number of adrenaline nebulization, treatment failure (requiring escalation of respiratory support), extubation failure, adverse events, and length of PICU stay in two groups. RESULTS: During the study period, 116 children were enrolled (58 each in HFNC and COT groups). There was no difference in rate of PEAO (55% vs. 51.7%, respectively), need of adrenaline nebulization, extubation failure, adverse events, and duration of PICU stay in two groups. However, the HFNC group had significantly lower rates of treatment failure (27.6% vs. 48.3%, p = 0.02). CONCLUSIONS: The rate of PEAO was similar in HFNC and COT groups. However, HFNC group had significantly lower rate of treatment failure requiring escalation of respiratory support.
RESUMO
BACKGROUND: Surgical aortic valve replacement (SAVR) is an established therapy for severe calcific aortic stenosis. Enhanced recovery after cardiac surgery (ERACS) protocols have been shown to improve outcomes for elective cardiac procedures. The COVID-19 pandemic prompted early extubation post-elective surgeries to preserve critical care resources. AIM OF THIS STUDY: To investigate the effects of extubating patients within 6 h post-elective SAVR on hospital and ICU length of stay, mortality rates, ICU readmissions, and postoperative pneumonia. STUDY DESIGN AND METHODS: The retrospective analysis at the University Hospital Aachen, Germany, includes data from 2017 to 2022 and compares a total of 73 elective SAVR patients. Among these, 23 patients were extubated within 6 h (EXT group), while 50 patients remained intubated for over 6 h (INT group). RESULTS: The INT group experienced longer postoperative ventilation, needed more vasopressor support, had a higher incidence of postoperative pneumonia, and longer ICU length of stay. No significant differences were noted in overall hospital length of stay, mortality, or ICU readmission rates between the groups. CONCLUSION: This study demonstrates that early extubation in high-risk, multimorbid surgical aortic valve replacement patients is safe, and is associated with a reduction of pneumonia rates, and with shorter ICU and hospital length of stays, reinforcing the benefits of ERACS protocols, especially critical during the COVID-19 pandemic to optimize intensive care use.

BACKGROUND: No large observational study has compared the incidence and risk factors for extubation failure within 48 hours and during intensive care unit (ICU) stay in the same cohort of unselected critically ill patients with and without obesity. RESEARCH QUESTION: Which are the incidence and risk factors of extubation failure in patients with and without obesity? STUDY DESIGN AND METHODS: In this prospective multicenter observational FREE-REA study in 26 intensive care units, the primary objective was to compare the incidence of extubation failure within 48 hours in patients with and without obesity. Secondary objectives were to describe and to identify the independent specific risk factors for extubation failure using first a logistic regression model and second a decision tree analysis. RESULTS: Of 1,370 extubation procedures analyzed, 288 (21%) were performed in patients with obesity and 1082 (79%) in patients without obesity. The incidence of extubation failure within 48 hours among patients with or without presence of obesity was 23/288 (8.0%) versus 118/1082 (11%) respectively; unadjusted odds ratio (OR) 0.71 95% confidence interval (CI, 0.45-1.13), P=0.15); alongside patients with obesity receiving significantly more noninvasive ventilation (87/288, 30% versus 233/1082, 22%, P=0.002) and physiotherapy (165/288, 57% versus 527/1082, 49%, P=0.02) than patients without obesity. Risk factors for extubation failure also differed according to obesity status: female gender [adjusted (a)OR 4.88 95%CI(1.61-13.9), P=0.002] and agitation before extubation [aOR 6.39 95%CI (1.91-19.8), P=0.001] in patients with obesity; absence of strong cough before extubation [aOR 2.38 95%CI (1.53-3.84), P=0.0002] and duration of invasive mechanical ventilation before extubation [aOR 1.03 per day 95%CI (1.01-1.06), P=0.01] in patients without obesity. The decision tree analysis found similar risk factors. INTERPRETATION: Our findings indicate that anticipation and application of preventive measures for patients with obesity before and after extubation led to similar rate of extubation failure among patients with and without obesity. CLINICAL TRIAL REGISTRATION: NCT XXX.
RESUMO
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.
RESUMO
OBJECTIVE: This study aims to reduce the waste generated from primary cleft lip and/or palate (CL/P) repair. DESIGN: A retrospective chart review examined a single surgeon's experience with CL/P repair using standard draping technique and reduced draping technique. Fisher's exact tests were performed comparing complication rates between techniques. SETTING: All procedures were conducted at a single academic medical center under the care of a board-certified pediatric plastic surgeon and fellowship-trained pediatric anesthesiologists. PATIENTS: The study included all patients ≤ 24 months of age who underwent primary CL/P repair using a reduced draping technique at the senior author's institution. An equivalent number of patients who underwent CL/P repair by the senior author immediately prior to implementation of the reduced draping technique were included for comparison. INTERVENTION: Patients undergoing CL/P repair before the change in technique were draped using the standard CL/P draping. The senior author then switched to using a reduced draping on all CL/P repairs afterwards. MAIN OUTCOME MEASURES: Weights and costs of both draping sets were obtained and differences calculated. A manual chart review was performed to assess rates of accidental intraoperative extubation, postoperative infection, fistula formation, and wound dehiscence. RESULTS: The implementation of a reduced draping technique resulted in a 530 gram weight savings and $7.49 cost savings per procedure. Fisher's exact tests revealed no statistically significant differences in complication rates except for oral mucosal dehiscence, which was lower in the reduced draping group. CONCLUSIONS: Reduced draping in CL/P repairs significantly reduces operative waste without compromising surgical outcomes.
RESUMO
Pediatric cardiac surgery poses significant challenges in developing countries, where a considerable number of children require intervention for congenital heart disease (CHD). The utilization of endotracheal intubation and anesthesia is pivotal in conducting surgical or angiography procedures on patients with CHD exhibiting diverse anatomical and hemodynamic characteristics. The decision to extubate pediatric patients following cardiac surgery remains a crucial element of postoperative care. This article explores the complexities surrounding extubation decision-making in this population, emphasizing the critical role of surgical, physiological, and postoperative factors. Various preoperative and intraoperative factors influence the timing of extubation. Early extubation is increasingly prevalent, offering benefits like reduced length of stay and minimized drug exposure. Multidisciplinary collaboration and protocol-driven strategies contribute to improved extubation outcomes, emphasizing the need for a comprehensive approach in pediatric cardiac surgery. Future research can focus on the implementation and efficacy of standardized extubation procedures involving collaboration among healthcare experts.
RESUMO
Background: Ventilator-dependent neonates are at risk of bronchopulmonary dysplasia (BPD), a chronic lung disease. Dexamethasone may be used to facilitate extubation and reduce the incidence of BPD. Objectives: To determine the efficacy of dexamethasone in reducing the incidence of established BPD at 36 weeks postmenstrual age (PMA); to establish the rate of extubation success; to determine the factors affecting extubation success; and to describe complications associated with dexamethasone therapy. Methods: A chart review was conducted at Surrey Memorial Hospital, in Surrey, British Columbia, for neonates who received dexamethasone to reduce the development of BPD between July 1, 2016, and June 30, 2022. Results: A total of 47 neonates met the inclusion criteria. Of the 45 neonates still alive at 36 weeks PMA, all (100%) had BPD. Use of dexamethasone led to extubation success for 21 (47%) of these 45 neonates. The mean PMA at dexamethasone initiation was 30.7 weeks for neonates with extubation success, compared with 28.6 weeks for those with extubation failure (p = 0.001). Complications occurred in 43 (91%) of the 47 neonates. Conclusions: BPD occurred in all of the neonates, despite a 47% extubation success rate. The timing of dexamethasone initiation was associated with extubation success. Further research is required to determine the dose and timing of dexamethasone needed to reduce the incidence of BPD.
Contexte: Les nouveau-nés qui dépendent d'un ventilateur sont exposés à un risque de dysplasie broncho-pulmonaire (DBP), une maladie pulmonaire chronique. La dexaméthasone peut être utilisée pour faciliter l'extubation et réduire l'incidence de cette maladie. Objectifs: Déterminer l'efficacité de la dexaméthasone pour réduire l'incidence de la DBP établie à 36 semaines d'âge postmenstruel (APM); établir la réussite de l'extubation; déterminer les facteurs ayant une incidence sur cette dernière; et décrire les complications associées au traitement par la dexaméthasone. Méthodologie: Un examen des dossiers a été effectué à l'hôpital Surrey Memorial, à Surrey (Colombie-Britannique) pour les nouveau-nés ayant reçu de la dexaméthasone entre le 1er juillet 2016 et le 30 juin 2022 afin de réduire le risque de DBP. Résultats: Au total, 47 nouveau-nés répondaient aux critères d'inclusion. Sur les 45 nouveau-nés encore en vie à 36 semaines d'APM, tous (100 %) souffraient de DBP. L'utilisation de dexaméthasone a permis de réussir l'extubation chez 21 (47 %) de ces 45 nouveau-nés. L'APM moyen au début de l'administration de la dexaméthasone était de 30,7 semaines pour les nouveau-nés dont l'extubation avait été réussie, contre 28,6 semaines pour ceux chez qui ce n'était pas le cas (p = 0,001). Des complications sont survenues chez 43 (91 %) des 47 nouveau-nés. Conclusions: La DBP est survenue chez tous les nouveau-nés, malgré un taux de réussite d'extubation de 47 %. Le moment du début de l'administration de la dexaméthasone était associé à la réussite de l'extubation réussie. Des recherches supplémentaires sont nécessaires pour déterminer la dose de dexaméthasone requise et le moment opportun de l'administration pour réduire l'incidence de la BPD.
RESUMO
Introduction. spontaneous breathing trial (SBT) in weaning from pediatric invasive mechanical ventilation (IMV) is an endorsed practice, its positivity is based on clinical parameters; however, its results could be better documented. Objective. To describe the results of the SBT in the IMV weaning process. Population and methods. Retrospective analysis. Patients with ≥48 h in IMV from March 1, 2022 to January 31, 2024. Results. A total of493 SBT were analyzed in 304 patients; 71% (348) were positive, and 87% (302) resulted in successful extubations. The causes of negative SBT were increased work of breathing (70%), respiratory rate (57%), and heart rate (27%). In univariate analysis, respiratory distress as the reason for admission, peak inspiratory pressure before SBT and T-tube use, were predictors of negative SBT. In multivariate analysis, this association persisted for admission for respiratory cause, the higher programmed respiratory rate in IMV, as the T-tube modality. Those with negative SBT stayed more days in IMV (9 [7-12] vs. 7 [4-10]) and in PICU (11 [9-15] vs. 9 [7-12]). Conclusion. Positive SBT predicted successful extubation in a high percentage of cases. Respiratory distress on admission, higher programmed respiratory rate, and a higher proportion of T-tube mode were negative predictors of the test. Negative SBT was associated with more extended stays in IMV and PICU.
Introducción. La prueba de ventilación espontánea (PVE) en el proceso de liberación de la asistencia ventilatoria mecánica invasiva (AVMi) pediátrica es una práctica avalada; su positividad se sustenta en parámetros clínicos. Sin embargo, sus resultados están escasamente documentados. Objetivo. Describir los resultados de la PVE en el proceso de liberación de la AVMi. Población y métodos. Análisis retrospectivo. Pacientes con ≥ 48 h en AVMi del 1 de marzo de 2022 al 31 de enero de 2024. Resultados. Se analizaron 493 PVE en 304 pacientes; el 71 % (348) fueron positivas y el 87 % (302) redundó en extubaciones exitosas. Las causas de las PVE negativas fueron mayor trabajo respiratorio (70 %), frecuencia respiratoria (57 %) y frecuencia cardíaca (27 %). En el análisis univariado, la dificultad respiratoria como motivo de ingreso, la presión inspiratoria máxima previo a la PVE y el uso de tubo en T fueron predictores de PVE negativa. En el análisis multivariado, esta asociación persistió para el ingreso por causa respiratoria, la mayor frecuencia respiratoria programada en la AVM y la modalidad tubo en T. Quienes presentaron PVE negativas permanecieron más días en AVMi [9 (7-12) vs. 7 (4-10)] y en UCIP [11 (9-15) vs. 9 (7-12)]. Conclusión. La PVE positiva predijo la extubación exitosa en un alto porcentaje. La dificultad respiratoria al ingreso, la mayor frecuencia respiratoria programada y la mayor proporción de la modalidad tubo en T fueron predictores negativos para la prueba. La PVE negativa se asoció a mayor estadía en AVMi y UCIP.
RESUMO
BACKGROUND: Post-extubation dysphagia (PED) emerges as a frequent complication following endotracheal intubation within the intensive care unit (ICU). PED has been strongly linked to adverse outcomes, including aspiration, pneumonia, malnutrition, heightened mortality rates, and prolonged hospitalization, resulting in escalated healthcare expenditures. Nevertheless, the reported incidence of PED varies substantially across the existing body of literature. Therefore, the principal objective of this review was to provide a comprehensive estimate of PED incidence in ICU patients undergoing orotracheal intubation. METHODS: We searched Embase, PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science, Technology Journal Database (VIP), and SinoMed databases from inception to August 2023. Two reviewers independently screened studies and extracted data. Subsequently, a random-effects model was employed for meta-statistical analysis utilizing the "meta prop" command within Stata SE version 15.0 to ascertain the incidence of PED. In addition, we performed subgroup analyses and meta-regression to elucidate potential sources of heterogeneity among the included studies. RESULTS: Of 4144 studies, 30 studies were included in this review. The overall pooled incidence of PED was 36% (95% confidence interval [CI] 29-44%). Subgroup analyses unveiled that the pooled incidence of PED, stratified by assessment time (≤ 3 h, 4-6 h, ≤ 24 h, and ≤ 48 h), was as follows: 31.0% (95% CI 8.0-59.0%), 28% (95% CI 22.0-35.0%), 41% (95% CI 33.0-49.0%), and 49.0% (95% CI 34.0-63.0%), respectively. When sample size was 100 < N ≤ 300, the PED incidence was more close to the overall PED incidence. Meta-regression analysis highlighted that sample size, assessment time and mean intubation time constituted the source of heterogeneity among the included studies. CONCLUSION: The incidence of PED was high among ICU patients who underwent orotracheal intubation. ICU professionals should raise awareness about PED. In the meantime, it is important to develop guidelines or consensus on the most appropriate PED assessment time and assessment tools to accurately assess the incidence of PED.

Introduction: Enhanced Recovery After Surgery (ERAS) prioritizes faster functional recovery after major surgery. An important aspect of postoperative ERAS is decreasing morbidity and immobility, which can result from prolonged critical care. Using current clinical data, our aim was to analyze whether a six-hour monitoring period after Minimally Invasive Cardiac Surgery (MICS) might be sufficient to recognize major postoperative complications in a future Fast Track pathway. Additionally, we sought to investigate whether it could be possible to deescalate the setting of postoperative monitoring. Methods: 358 patients received MICS and were deemed suitable for an ERAS protocol between 01/2021 and 03/2023 at our institution. Of these, 297 patients could be successfully extubated on-table, were transferred to IMC or ICU in stable condition and therefore served as study cohort. Outcomes of interest were incidence and timing of Major Adverse Cardiac Events (MACE; death, myocardial infarction requiring revascularization, stroke), bleeding requiring reexploration and Fast Track-associated complications (reintubation and readmission to ICU). Results: Patients' median age was 63 years (IQR 55-70) and 65% were male. 189 (64%) patients received anterolateral mini-thoracotomy, primarily for mitral and/or tricuspid valve surgery (n = 177). 108 (36%) patients had partial upper sternotomy, primarily for aortic valve repair/replacement (n = 79) and aortic surgery (n = 17). 90% of patients were normotensive without need for vasopressors within 6â h postoperatively, 82% of patients were transferred to the general ward on postoperative day 1 (POD). Two (0.7%) MACE events occurred, as well as 4 (1.3%) postoperative bleeding events requiring reexploration. Of these complications, only one event occurred before transfer to the ward - all others took place on or after POD 1. There was one instance of reintubation and two of readmission to ICU. Conclusions: If MICS patients can be successfully extubated on-table and are hemodynamically stable, major postoperative complications were rare in our single-center experience and primarily occurred after transfer to the ward. Therefore, in well selected MICS patients with uncomplicated intraoperative course, monitoring for six hours, possibly outside of an ICU, followed by transfer to the ward appears to be a feasible theoretical concept without negative impact on patient safety.
RESUMO
INTRODUCTION: Prolonged times to tracheal extubation are intervals from the end of surgery to extubation ≥15 minutes. We examined why there are associations with the end-tidal inhalational agent concentration as a proportion of the ageadjusted minimum alveolar concentration (MAC fraction) at the end of surgery. METHODS: The retrospective cohort study used 11.7 years of data from one hospital. All pvalues were adjusted for multiple comparisons. RESULTS: There was a greater odds of prolonged time to extubation if the anesthesia practitioner was a trainee (odds ratio 1.68) or had finished fewer than five cases with the surgeon during the preceding three years (odds ratio 1.12) (both P<0.0001). There was a greater risk of prolonged time to extubation if the MAC fraction was >0.4 at the end of surgery (odds ratio 2.66, P<0.0001). Anesthesia practitioners who were trainees and all practitioners who had finished fewer than five cases with the surgeon had greater mean MAC fractions at the end of surgery and had greater relative risks of the MAC fraction >0.4 at the end of surgery (all P<0.0001). The source for greater MAC fractions at the end of surgery was not greater MAC fractions throughout the anesthetic because the means during the case did not differ among groups. Rather, there was substantial variability of MAC fractions at the end of surgery among cases of the same anesthesia practitioner, with the mean (standard deviation) among practitioners of each practitioner's standard deviation being 0.35 (0.05) and the coefficient of variation being 71% (13%). CONCLUSION: More prolonged extubations were associated with greater MAC fractions at the end of surgery. The cause of the large MAC fractions was the substantial variability of MAC fractions among cases of each practitioner at the end of surgery. That variability matches what was expected from earlier studies, both from variability among practitioners in their goals for the MAC fraction given at the start of surgical closure and from inadequate dynamic forecasting of the timing of when surgery would end. Future studies should examine how best to reduce prolonged extubations by using anesthesia machines' display of MAC fraction and feedback control of end-tidal agent concentration.
RESUMO
Background: The reduced mobility in critically ill patients is still a reality in many intensive care units. This study aims to investigate if mobility level is associated with extubation outcome in adult patients.Methods: Prospective cohort study which comprised adults who had undergone initial invasive mechanical ventilation for more than 24 hours and were independently mobile before hospitalization. Patient progress was monitored from ICU admission to discharge. Data were collected daily from medical records and multidisciplinary teams, considering variables such as age, sex, BMI, SAPS III score, type of ICU admission, comorbidities, sedation, usage of vasoactive drugs, neuromuscular blockers, duration of mechanical ventilation, and ICU mobility scale (IMS). The primary outcome was the success of extubation.Results: IMS values did not directly associate with extubation outcome. Older patients demonstrated a reduced tendency for high IMS values, as did those on prolonged usage of vasoactive drugs or mechanical ventilation. Patients with higher IMS values achieved successful extubation earlier, suggesting a link between mobility and faster extubation success.Conclusion: The level of mobility assessed 24 hours after extubation was not associated with extubation success. The following characteristics were associated with a lower propensity to present high IMS: older age, greater number of days of use of vasoactive drugs and mechanical ventilation. Patients with higher levels of mobility had a successful extubation event earlier in the ICU. Studies that assess mobility on a continuous basis would be more precise in identifying this association.
RESUMO
OBJECTIVE: To assess the effect of ultrasound-guided bilateral erector spinae plane block (ESPB) on the time to extubation in patients who had undergone cardiac surgery through a midline sternotomy. DESIGN: Randomized controlled trial. SETTING: Cairo University Hospital and National Heart Institute, Egypt. PARTICIPANTS: Patients aged 18 to 70 years who underwent a cardiac surgical procedure through a midline sternotomy. INTERVENTIONS: Recruited patients were randomized to receive either preoperative single-shot ultrasound-guided bilateral ESPB or fentanyl infusion. MEASUREMENTS: The primary outcome was the time to extubation. Other outcomes included total perioperative fentanyl consumption, pain score using the numerical rating score (NRS), length of intensive care unit (ICU) stay, and incidence of perioperative complications. MAIN RESULTS: Two hundred and nineteen patients were available for final analysis. The mean time to extubation was significantly shorter In the ESPB group compared to the control group (159.5 ± 109.5 minutes vs 303.2 ± 95.9 minutes; mean difference, -143.7 minutes; 95% confidence interval, -171.1 to -116.3 minutes; p = 0.0001). Ultra-fast track (immediate postoperative) extubation was achieved in 23 patients (21.1%) in the ESPB group compared to only 1 patient (0.9%) in the control group. The ICU stay was significantly reduced in the ESPB group compared to the control group (mean, 47.2 ± 13.3 hours vs 78.9 ± 25.2 hours; p = 0.0001). There was a more significant reduction in NRS in the ESPB group compared to the control group for up to 24 hours postoperatively (p = 0.001). CONCLUSIONS: Among adult patients undergoing cardiac surgery through a midline sternotomy, the extubation time was halved in patients who received single-shot bilateral ESPB compared to patients who received fentanyl infusion.
RESUMO
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.

This pilot study aimed to investigate the relation between cardio-respiratory parameters derived from Central Venous Pressure (CVP) waveform and Extubation Failure (EF) in mechanically ventilated ICU patients during post-extubation period. This study also proposes a new methodology for analysing these parameters during rest/sleep periods to try to improve the identification of EF. We conducted a prospective observational study, computing CVP-derived parameters including breathing effort, spectral analyses, and entropy in twenty critically ill patients post-extubation. The Dynamic Warping Index (DWi) was calculated from the respiratory component extracted from the CVP signal to identify rest/sleep states. The obtained parameters from EF patients and patients without EF were compared both during arbitrary periods and during reduced DWi (rest/sleep). We have analysed data from twenty patients of which nine experienced EF. Our findings may suggest significantly increased respiratory effort in EF patients compared to those successfully extubated. Our study also suggests the occurrence of significant change in the frequency dispersion of the cardiac signal component. We also identified a possible improvement in the differentiation between the two groups of patients when assessed during rest/sleep states. Although with caveats regarding the sample size, the results of this pilot study may suggest that CVP-derived cardio-respiratory parameters are valuable for monitoring respiratory failure during post-extubation, which could aid in managing non-invasive interventions and possibly reduce the incidence of EF. Our findings also indicate the possible importance of considering sleep/rest state when assessing cardio-respiratory parameters, which could enhance respiratory failure detection/monitoring.
