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

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

Dysphagia characteristics at FEES examination in post-extubation patients with COVID-19.

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.

Effect of early vs. delayed extubation on functional outcome among patients with acute ischemic stroke treated with endovascular thrombectomy under general anesthesia: the prospective, randomized controlled EDESTROKE trial study protocol.

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.

Reducing NICU Unplanned Extubations From Tube Dislodgement.

OBJECTIVES: Unplanned extubations (UEs) can be a frequent problem and are associated with adverse outcomes. This quality improvement initiative sought to reduce UEs from tube dislodgement in a level IV NICU utilizing methods applicable to other ICUs and performed with minimal monetary funds. METHODS: From January 2019 to July 2023, an interdisciplinary quality improvement team used the Model for Improvement and performed sequential interventions to improve the outcome measure of UEs per 100 ventilator days. Process measures included adherence to a modified, site-specific UE care bundle derived from the Solutions for Patient Safety network, whereas the number of endotracheal tube-related pressure injuries was used as a balancing measure. Statistical process control charts and established rules for special cause variation were applied to analyze data. RESULTS: Sequential interventions reduced the rate of UEs from a baseline of 2.3 to 0.6 UEs per 100 ventilator days. Greater than 90% adherence with the UE care bundle and apparent cause analysis form completion occurred since December 2020. There were no endotracheal tube-related pressure injuries. CONCLUSIONS: A sustained reduction in UEs was demonstrated. Leveraging a multidisciplinary team allowed for continuous UE analysis, which promoted tailored consecutive interventions. UE care bundle audits and the creation of a postevent debrief guide, which helped providers share a common language, were the most impactful interventions. Next steps include disseminating these interventions to other ICUs across our hospital enterprise. These low-cost interventions can be scalable to other NICUs and PICUs.

Investigating the risk of reintubation by cough force assessment using cough peak expiratory flow: a single-center observational pilot study.

BACKGROUND: No objective indicator exists for evaluating cough strength during extubation of tracheally intubated patients. This study aimed to determine whether cough peak expiratory flow (CPEF) can predict the risk of reintubation due to decreased cough strength. METHODS: This was a retrospective cohort study of patients who were admitted to our Emergency Intensive Care Unit between September 1, 2020 and August 31, 2021 and were under artificial ventilation management for ≥ 24 h. The patients were divided into two groups: successful extubation and reintubation groups, and the relationship between CPEF immediately before extubation and reintubation was investigated. RESULTS: Seventy-six patients were analyzed. In the univariate analysis, CPEF was significantly different between the successful extubation (90.7 ± 25.9 L/min) and reintubation (57.2 ± 6.4 L/min) groups (p < 0.001). In the multivariate analysis with age and duration of artificial ventilation as covariates, CPEF was significantly lower in the reintubation group (p < 0.01). The cutoff value of CPEF for reintubation according to the receiver operating characteristic curve was 60 L/min (area under the curve, 0.897; sensitivity, 78.5%; specificity, 90.9%; p < 0.01). CONCLUSION: CPEF in tracheally intubated patients may be a useful indicator for predicting the risk of reintubation associated with decreased cough strength. The cutoff CPEF value for reintubation due to decreased cough strength was 60 L/min.

Effect of Intravenous Dexmedetomidine Before Extubation on Emergence Delirium after Nasal Surgeries.

OBJECTIVE: To investigate the role of single dose of dexmedetomidine (0.5 mcg/kg) in reducing the incidence and severity of postoperative emergence delirium (EmD). STUDY DESIGN: A randomised controlled trial. Place and Duration of the Study: Department of Anaesthesia, Security Forces Hospital, Riyadh, Saudi Arabia, from 1st December 2022 to 30th March 2023. METHODOLOGY: Patients, aged between 18-65 years, with ASA 1-3 scheduled to undergo nasal surgeries under general anaesthesia, were inducted in the study. Exclusion criteria were patient refusal, later request for removal from the study, inability to give consent, known allergy to dexmedetomidine, body mass index (BMI) more than 35, history of obstructive sleep apnoea, history of psychiatric illness, pregnancy, and presence of liver and renal diseases. The primary outcome measure of the study was the incidence of emergence delirium in the postoperative period. RESULTS: The frequency of EmD after nasal surgery was 52.38% in the control group compared to 14.28% in the dexmedetomidine group (p = 0.01). Pain scores were not statistically different between the two groups. The duration of post anaesthesia care unit (PACU) stay was significantly lesser in dexmedetomidine group (p <0.001). The satisfaction score on the visual analogue scale (VAS) was also found to be higher in patients who received intravenous dexmedetomidine (p <0.001). CONCLUSION: The use of single dose dexmedetomidine before extubation in nasal surgeries reduces the EmD and improves patient satisfaction. KEY WORDS: Dexmedetomidine, Emergence delirium, Nasal surgery, Opioid consumption, Pain control.

The use of two or more courses of low-dose systemic dexamethasone to extubate ventilator-dependent preterm neonates may be associated with a higher prevalence of cerebral palsy at two years of corrected age.

BACKGROUND: Our objective was to determine whether the use of two or more courses of low-dose systemic dexamethasone for extubation of ventilator-dependent preterm infants after the first week of life, as proposed in the DART study, is associated with greater neurodevelopmental harm at two years of corrected age, compared to a single course. METHODS: Retrospective review at seven level III neonatal intensive care units. Preterm infants who underwent only one course of systemic dexamethasone for extubation were grouped into DART-1; those who underwent two or more courses were grouped into DART-2. Data and outcomes of infants in DART-2 were compared with those in DART-1. RESULTS: 150 preterm infants were studied: 104 in DART-1 and 46 in DART-2. Patients in DART-2 had a lower gestational age (25 vs. 26 weeks, p = 0.031) and greater morbidity. The average dexamethasone cumulative dose for patients in DART-1 was 0.819 mg/kg, vs. 1.697 mg/kg for patients in DART-2. A total of 14 patients died. The neuromotor and neurosensory assessments at two years of corrected age revealed in the DART-2 survivors, after the multivariate analysis, a higher prevalence of cerebral palsy with functional motor class 2 (OR = 6.837; 95%CI: 1.054-44.337; p = 0.044) and ophthalmological problems requiring the use of glasses (OR = 4.157; 95%CI: 1.026-16.837; p = 0.046). CONCLUSIONS: In this cohort, the use of more than one course of systemic dexamethasone in low doses for extubation of ventilator-dependent premature infants after the first week of life was associated, at two years of corrected age, with a higher prevalence of cerebral palsy with functional motor class 2 and ophthalmological problems requiring the use of glasses.

Postorotracheal intubation dysphagia in patients with COVID-19: A retrospective study.

BACKGROUND: The cause of oropharyngeal dysphagia in patients with coronavirus disease (COVID-19) can be multifactorial and may underly limitations in swallowing rehabilitation. OBJECTIVE: Analyze the factors related to dysphagia in patients with COVID-19 immediately after orotracheal extubation and the factors that influence swallowing rehabilitation. DESIGN AND SETTING: A retrospective study. METHODS: The presence of dysphagia was evaluated using the American Speech-Language Hearing Association National Outcome Measurement System (ASHA NOMS) scale and variables that influenced swallowing rehabilitation in 140 adult patients who required invasive mechanical ventilation for >48 h. RESULTS: In total, 46.43% of the patients scored 1 or 2 on the ASHA NOMS (severe dysphagia) and 39.29% scored 4 (single consistency delivered orally) or 5 (exclusive oral diet with adaptations). Both the length of mechanical ventilation and the presence of neurological disorders were associated with lower ASHA NOMS scores (odds ratio [OR]: 0.80, 95% confidence interval [CI]: 0.74-0.87 P < 0.05; and OR: 0.13, 95% CI: 0.61-0.29; P < 0.05, respectively). Age and the presence of tracheostomy were negatively associated with speech rehabilitation (OR: 0.92; 95% CI: 0.87--0.96; OR: 0.24; 95% CI: 0.80--0.75), and acute post-COVID-19 kidney injury requiring dialysis and lower scores on the ASHA NOMS were associated with longer time for speech therapy outcomes (ß: 1.62, 95% CI, 0.70-3.17, P < 0.001; ß: -1.24, 95% CI: -1.55--0.92; P < 0.001). CONCLUSION: Prolonged orotracheal intubation and post-COVID-19 neurological alterations increase the probability of dysphagia immediately after extubation. Increased age and tracheostomy limited rehabilitation.

The effect of erector spinae plane block on postoperative extubation time and laboratory parameters in open heart surgery: a retrospective study.

Background/aim: In open heart surgery, sternotomy causes inflammation in tissues, and inflammation causes postoperative pain. This study aims to examine the effects of bilateral erector spinae plane (ESP) blocks on postoperative extubation time and laboratory parameters in open heart surgery. Materials and methods: The study was managed using retrospective data from 85 patients who underwent open-heart surgery. Patients who received intravenous analgesia and were transferred to the intensive care unit with intubation were included in the study. Two groups were formed: those who received preoperative bilateral ESP block (ESB) and those nonblock (NB). Statistical significance was investigated between ESB and NB in terms of extubation time and laboratory parameters. Results: The postoperative extubation time for group NB was significantly longer at 360 (300-420) min compared to the observed 270 (240-390) min for ESB (p: 0.006). The length of stay in the intensive care unit was also longer for group NB at 4 (3-5) days compared to 3 (3-4) days for ESB (p: 0.001). Ejection fraction values, cardiopulmonary bypass, and aortic cross-clamp times were similar in both groups. Postoperative 24 h troponin I levels were higher for group NB at 0.94 (0.22-2.70) mcg/L compared to 0.16 (0.06-1.40) mcg/L for group ESB (p: 0.016). Conclusion: It would be useful for anesthesiologists to know that erector spinae plane blocks applied in the preoperative period in cardiac surgeries not only shorten the mechanical ventilation and hospitalization times but also provide lower troponin values in the postoperative period patient follow-ups.

The effect of deep and awake extubation on emergence agitation after nasal surgery: a randomized controlled trial.

BACKGROUND: Post-anesthetic emergence agitation is common after general anesthesia and may cause adverse consequences, such as injury as well as respiratory and circulatory complications. Emergence agitation after general anesthesia occurs more frequently in nasal surgery than in other surgical procedures. This study aimed to assess the occurrence of emergence agitation in patients undergoing nasal surgery who were extubated under deep anesthesia or when fully awake. METHODS: A total of 202 patients (18-60 years, American Society of Anesthesiologists classification: I-II) undergoing nasal surgery under general anesthesia were randomized 1:1 into two groups: a deep extubation group (group D) and an awake extubation group (group A). The primary outcome was the incidence of emergence agitation. The secondary outcomes included number of emergence agitations, sedation score, vital signs, and incidence of adverse events. RESULTS: The incidence of emergence agitation was lower in group D than in group A (34.7% vs. 72.8%; p < 0.001). Compared to group A, patients in group D had lower Richmond Agitation-Sedation Scale scores, higher Ramsay sedation scores, fewer agitation episodes, and lower mean arterial pressure when extubated and 30 min after surgery, whereas these indicators did not differ 90 min after surgery. There was no difference in the incidence of adverse events between the two groups. CONCLUSIONS: Extubation under deep anesthesia can significantly reduce emergence agitation after nasal surgery under general anesthesia without increasing the incidence of adverse events. TRIAL REGISTRATION: Registered in Clinicaltrials.gov (NCT04844333) on 14/04/2021.

Impact of Cluster Nursing Intervention on ICU Patients' Psychological Well-Being and Complications Associated with Tracheal Intubation and Extubation.

BACKGROUND Nurses in the Intensive Care Unit (ICU) play a critical role in recognizing patients who are at risk of deterioration by conducting continual assessments and taking suitable measures in response to changing health status. The validity of the cluster nursing intervention has been studied previously, but its use among ICU patients with tracheal intubation and extubation has not been examined. This study assessed the effectiveness of cluster nursing intervention in ICU patients with tracheal intubation and extubation. MATERIAL AND METHODS In this retrospective study, 80 patients on mechanical ventilation in the ICU ward were randomly assigned to control and intervention groups (40 patients each). The control group received the routine nursing mode, while the intervention group was given 5 sessions of cluster nursing intervention. Tracheal intubation and extubation-associated complications, blood gas analysis, patient nursing satisfaction, and changes in patients' negative emotions were compared before and after the intervention. RESULTS After the nursing intervention, the levels of PaO2 were higher, while PaCO2 levels were lower in the intervention group compared to the control group (P<0.05). Importantly, anxiety and depression scores in the intervention group were lower than in the control group (P<0.05). Moreover, the overall incidence of complications in the intervention group was lower than in the control group, whereas patient satisfaction with nursing services was higher (P<0.05). CONCLUSIONS Cluster nursing intervention can effectively reduce the incidence of complications and improve patients’ physiological and psychological conditions. Moreover, it enhances patient satisfaction with nursing services, thus improving patients' clinical symptoms.

Surfactant administration methods for premature newborns: LISA vs. INSURE comparative analysis.

INTRODUCTION: Respiratory Distress Syndrome (RDS) is the most common respiratory disorder among premature infants. The use of surfactant has significantly reduced respiratory complications and mortality. There are two conventional methods for administering surfactant: Intubate-Surfactant-Extubate (INSURE) and Less Invasive Surfactant Administration (LISA). This study aims to compare the effects of surfactant administration using these two methods on the treatment outcomes of premature newborns. MATERIALS AND METHODS: In this retrospective cohort study, we included 100 premature newborns with RDS and spontaneous breathing who were admitted to the Neonatal Intensive Care Unit of Besat Hospital in Sanandaj city in 2021. Exclusion criteria comprised congenital anomalies and the needing for intubation for resuscitation at birth. The outcomes of epmericaly trated with two methods were compared: the LISA (50 neonates) and the INSURE (50 neonates). Our interesting outcomes were needing for mechanical ventilation, duration of ventilation, pneumothorax, pulmonary hemorrhage, severe retinopathy, CPAP duration, and bronchopulmonary dysplasia. Finally, we entered the data into STATA-14 statistical software and analyzed it using chi-square and t-tests. RESULTS: In this study, 69% of the neonates were boys. The LISA group exhibited significantly lower rates of need for mechanical ventilation (P = 0.003) and ventilation duration (P < 0.001) compared to the INSURE group. Conversely, there were no significant differences between the two groups (P > 0.05) in terms of pneumothorax, pulmonary hemorrhage, severe retinopathy, CPAP duration, and bronchopulmonary dysplasia rates. CONCLUSION: The results of this study suggest that the LISA method is a safe and non-invasive approach for surfactant administration. Notably, it resulted in a reduced need for mechanical ventilation and decreased ventilation duration compared to the INSURE method.

The effect of enhanced recovery after lung cancer surgery combined with fine surgical nursing on rehabilitation.

Objectives: To analyse the enhanced recovery after surgery approach combined with fine surgical nursing on recovery time, pain, sleep quality and satisfaction with care after lung cancer surgery. METHODS: The cross-sectional study was conducted at the Nanjing Chest Hospital, China, from October 2019 to March 2022, and comprised non-small cell lung cancer patients undergoing single-port video-assisted thoracoscopic surgery. Patients receiving fine surgical nursing in addition to conventional enhanced recovery after surgery formed the intervention group A, while those receiving the conventional enhanced recovery after surgery care alone formed control group B. Intraoperative blood loss, operative time, extubation time and length of stay values were noted for both the groups using standard scales. Nursing satisfaction and the incidence of adverse reactions in the two groups were also noted. Data was analysed using SPSS 23. RESULTS: Of the 99 patients, 46(46.5%) were in group A; 23(50%) males and 23(50%) females with mean age 70.3±4.8 years and mean body mass index 26.76±2.55kg/m2. There were 53(53.5%) patients in group B: 16(30.2%) males and 37(69.8%) females with mean age 69.9±4.4 years and mean body mass index 25.93±2.40kg/m2 (p>0.05). Intraoperative blood loss, operative time, postoperative extubation time and length of stay in group A were lower than those in group B (p<0.05). Pain and sleep quality values in group A were lower, while health status value was higher than group B (p<0.05). Group A had significantly higher nursing satisfaction compared to group B (p<0.05). Conclusion: The use of enhanced recovery after surgery combined with fine surgical nursing in patients with nonsmall cell lung cancer after video-assisted thoracoscopic surgery promoted postoperative recovery.

Assessing the reproducibility and predictive value of objective cough measurement for successful withdrawal of invasive ventilatory support in adult patients.

BACKGROUND: Utilizing clinical tests, such as objective cough measurement, can assist in predicting the success of the weaning process in critically ill patients. METHODS: A multicenter observational analytical study was conducted within a prospective cohort of patients recruited to participate in COBRE-US. We assessed the capability of objective cough measurement to predict the success of the spontaneous breathing trial (SBT) and extubation. Intra- and inter-observer reproducibility of the cough test and was evaluated using the intraclass correlation coefficient (ICC) and Cohen's weighted kappa. We used receiver operating characteristic curves (ROC-curve) to evaluate the predictive ability of objective cough measurement. RESULTS: We recruited 367 subjects who were receiving invasive mechanical ventilation. A total of 451 objective cough measurements and 456 SBTs were conducted. A significant association was found between objective cough measurement and successful SBT (OR: 1.68; 95% CI 1.48-1.90; p = 0.001). The predictive capability of the objective cough test for SBT success had a ROC-curve of 0.58 (95% CI: 0.56-0.61). Objective cough measurement to predict successful extubation had a ROC-curve of 0.61 (95% CI: 0.56-0.66). The intraobserver reproducibility exhibited an ICC of 0.94 (95% CI: 0.89-0.96; p < 0.001), while the interobserver reproducibility demonstrated an ICC of 0.72 (95% CI: 0.51-0.85; p < 0.001). The intraobserver agreement, assessed using Cohen's weighted kappa was 0.94 (95% CI: 0.93-0.99; p < 0.001), whereas the interobserver agreement was 0.84 (95% CI: 0.67 - 0.10; p < 0.001). CONCLUSIONS: The objective measurement of cough using the method employed in our study demonstrates nearly perfect intra-observer reproducibility and agreement. However, its ability to predict success or failure in the weaning process is limited.

Risk factors for delayed extubation after pediatric perineal anaplasty in patients less than 1 year of age: a retrospective study.

BACKGROUND: Anorectal malformation is a common congenital problem occurring in 1 in 5,000 births and has a spectrum of anatomical presentations, requiring individualized surgical treatments for normal growth. Delayed extubation or reintubation may result in a longer intensive care unit (ICU) stay and hospital stay, increased mortality, prolonged duration of mechanical ventilation, increased tracheostomy rate, and higher hospital costs. Extensive studies have focused on the role of risk factors in early extubation during major infant surgery such as Cardiac surgery, neurosurgery, and liver surgery. However, no study has mentioned the influencing factors of delayed extubation in neonates and infants undergoing angioplasty surgery. MATERIALS AND METHODS: We performed a retrospective study of neonates and infants who underwent anorectal malformation surgery between June 2018 and June 2022. The principal goal of this study was to observe the incidence of delayed extubation in pediatric anorectal malformation surgery. The secondary goals were to identify the factors associated with delayed extubation in these infants. RESULTS: We collected data describing 123 patients who had anorectal malformations from 2019 to 2022. It shows that 74(60.2%) in the normal intubation group and 49(39.8%) in the longer extubation. In the final model, anesthesia methods were independently associated with delayed extubation (P < 0.05). CONCLUSION: We found that the anesthesia method was independently associated with early extubation in neonates and infants who accepted pediatric anorectal malformation surgery.

Factors Associated With Time to Decannulation in Patients With Tracheostomy Following Severe Traumatic Brain Injury.

BACKGROUND: Prolonged tracheal tube placement following severe traumatic brain injury (TBI) can cause serious complications. Safe removal requires sufficient ability for independent breathing and airway protection. Thus, identifying important factors for time to removal of the tracheal tube (decannulation) is essential for safe and efficient weaning. This study aimed to identify significant factors for time to decannulation in a Danish population of subjects with tracheostomy after TBI. METHODS: This was a retrospective register-based cohort study. Subjects with moderate and severe TBI and a tracheal tube were selected from the Danish Head Trauma Database between 2011-2021. Time to decannulation was calculated as time from injury to decannulation. Associations between selected explanatory variables representing demographic and clinical characteristics and time to decannulation were analyzed using linear regression models. RESULTS: A total 324 subjects were included with a median of 44 d to decannulation. Primary analysis found that an improvement in swallowing ability during the initial 4 weeks of rehabilitation was associated with an 8.2 d reduction in time to decannulation (95% CI -12.3 to -4.2, P < .001). Change in overall sensorimotor ability reduced time to decannulation by 0.94 (95% CI -0.78 to -0.10, P = .03) d. Change in cognitive abilities from rehab admission to 4-week follow-up did not significantly affect the number of days to decannulation (P = .66). Secondary analysis showed pneumonia was associated with the largest estimated increase of 24.4 (95% CI 15.9-32.9, P < .001) d and that increased cognitive functioning at rehabilitation admission was associated with a significant reduction in time to decannulation. CONCLUSIONS: This study found that a change in swallowing ability is a potentially significant factor for reducing time to decannulation. Identifying factors that could explain differences in time to decannulation is essential for patient outcomes, especially if these factors are modifiable and could be targeted in rehabilitation and treatment.
