Prevalence, Predictors, and Outcomes of Prolonged Mechanical Ventilation After Endovascular Stroke Therapy.

ABSTRACT: BACKGROUND:To investigate the rates, predictors, and outcomes of prolonged mechanical ventilation (??96 h) following endovascular treatment (EVT) of ischemic stroke. METHODS:Hospitalizations with acute ischemic stroke and EVT were identified using validated codes in the National Inpatient Sample (2010-2015). The primary outcome was prolonged mechanical ventilation defined as ventilation???96 consecutive hours. We compared hospitalizations involving prolonged ventilation following EVT with those that did not involve prolonged ventilation. Propensity score matching was used to adjust for differences between groups. Clinical predictors of prolonged ventilation were assessed using multivariable conditional logistic regression analyses. RESULTS:Among the 34,184 hospitalizations with EVT, 5087 (14.9%) required prolonged mechanical ventilation. There was a decline in overall intubation and prolonged ventilation during the study period. On multivariable analysis, history of heart failure [OR 1.28 (95% CI 1.05-1.57)] and diabetes [OR 1.22 (95% CI 1-1.50)] was independent predictors of prolonged ventilation following EVT. In a sensitivity analysis of anterior circulation stroke only, heart failure [OR 1.3 (95% CI 1.10-1.61)], diabetes [OR 1.25 (95% CI 1.01-1.57)], and chronic lung disease [OR 1.31 (95% CI 1.03-1.66)] were independent predictors of prolonged ventilation. The weighted proportions of in-hospital mortality, post-procedural shock, acute renal failure, and intracerebral hemorrhage were higher in the prolonged ventilation group. CONCLUSIONS:Among a nationally representative sample of hospitalizations, nearly one-in-six patients had prolonged mechanical ventilation after EVT. Heart failure and diabetes were significantly associated with prolonged mechanical ventilation following EVT. Prolonged ventilation was associated with significant increase in in-hospital mortality and morbidity.

Project description:ObjectivesUpper airway injury is a recognized complication of prolonged endotracheal intubation, yet little attention has been paid to the consequences of laryngeal injury and functional impact. The purpose of our study was to prospectively define the incidence of acute laryngeal injury and investigate the impact of injury on breathing and voice outcomes.DesignProspective cohort study.SettingTertiary referral critical care center.PatientsConsecutive adult patients intubated greater than 12 hours in the medical ICU from August 2017 to May 2018 who underwent laryngoscopy within 36 hours of extubation.InterventionsLaryngoscopy following endotracheal intubation.Measurements and main resultsOne hundred consecutive patients (62% male; median age, 58.5 yr) underwent endoscopic examination after extubation. Acute laryngeal injury (i.e., mucosal ulceration or granulation tissue in the larynx) was present in 57 patients (57%). Patients with laryngeal injury had significantly worse patient-reported breathing (Clinical Chronic Obstructive Pulmonary Disease Questionnaire: median, 1.05; interquartile range, 0.48-2.10) and vocal symptoms (Voice Handicap Index-10: median, 2; interquartile range, 0-6) compared with patients without injury (Clinical Chronic Obstructive Pulmonary Disease Questionnaire: median, 0.20; interquartile range, 0-0.80; p < 0.001; and Voice Handicap Index-10: median, 0; interquartile range, 0-1; p = 0.005). Multivariable logistic regression independently associated diabetes, body habitus, and endotracheal tube size greater than 7.0 with the development of laryngeal injury.ConclusionsAcute laryngeal injury occurs in more than half of patients who receive mechanical ventilation and is associated with significantly worse breathing and voicing 10 weeks after extubation. An endotracheal tube greater than size 7.0, diabetes, and larger body habitus may predispose to injury. Our results suggest that acute laryngeal injury impacts functional recovery from critical illness.

Project description:BACKGROUND AND PURPOSE:Despite strong evidence for endovascular therapy in adults with acute arterial ischemic stroke, limited data exist in children. We aimed to describe endovascular therapy utilization and explore outcomes in a national sample of pediatric arterial ischemic stroke. METHODS:We queried the 2012 Kids' Inpatient Database for children aged greater than 28 days to 20 years with the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for arterial ischemic stroke and evaluated groups based on the procedure code for endovascular therapy. Poor outcome was defined as need for tracheostomy or gastrostomy, discharge to rehabilitation facility, or death. Logistic regression evaluated the association between endovascular therapy and poor outcome, adjusted for age, disease severity (hemiplegia, critical care interventions, neurosurgical interventions), and comorbidities. RESULTS:We identified 3184 pediatric discharges with a diagnosis code for arterial ischemic stroke. Thirty-eight (1%) had an endovascular therapy procedure code. Endovascular therapy patients were older (10.2 versus 4.5 years, P < 0.001) and more likely to have hemiplegia/paresis (relative risk [RR] 3.8, 95% confidence interval [CI] 2.0-7.4), aphasia (RR 5.3, 95% CI 2.8-10.1), and facial droop (RR 4.0, 95% CI 1.9-8.7). Endovascular therapy was not associated with critical care and neurosurgical interventions or intracranial hemorrhage. Length of hospitalization, mortality, and discharge disposition were similar between groups. In a multivariable model, endovascular therapy was not associated with poor outcome (adjusted odds ratio 1.7, 95%, CI 0.7-4.1). CONCLUSIONS:In a national sample of children with a diagnosis of arterial ischemic stroke, endovascular therapy was infrequently utilized. Patients with a procedure code for endovascular therapy had significant stroke-related deficits, but outcomes were similar to those in children who did not receive endovascular therapy. Our data, in conjunction with evidence of benefit in adults, support consideration of endovascular therapy for select children with acute stroke.

Project description:Background A consensus on the definition of prolonged mechanical ventilation (PMV) for children does not exist. There is still lack of published work presenting the epidemiology, risk factors and outcomes at different cut-points for PMV patients. These are important for planning the goals of treatment and counseling of the prognosis for patient families. We aimed to determine the incidence, baseline characteristics, risk factors and outcomes of PMV in pediatric patients at various cut-points (>14, >21 or >30days). Methods A retrospective cohort study among children <18-years-old who were PMV > 14 days in the PICU of King Chulalongkorn Memorial Hospital was conducted. The primary outcomes were incidence of PMV with various cut-points. We stratified patients into three groups (Group 1; PMV > 14–21, Group 2; >21–30, Group 3; >30 days) for evaluating the baseline characteristics, risk factors, and outcomes of PMV (extubation success, tracheostomy status and death). Factors associated with PMV and deaths were analyzed using univariate and multivariate logistic regression. Results From January 2018 to August 2022, 1,050 patients were screened. Of these, 114 patients were enrolled. The incidence of PMV > 14, >21 and >30 days were 10.9%, 7.3% and 5.0% respectively. Extubation success was significantly lower in Group 3 than in Groups 1 & 2 (15.4% vs. 62.2% & 56.0%, P < 0.001). Consequently, the tracheostomy rate (63.5% vs. 16.2% & 12.0%, P < 0.001), VAP rate (98.1% vs. 59.5% & 80.0%, P < 0.001), mortality rate by disease (34.6% vs. 5.4% & 20.0%, P = 0.003), median PICU LOS (50.5 vs. 22.0 & 28.0 days, P < 0.001) and median hospital LOS (124.5 vs. 55.0 & 62.0 days, P < 0.001) were also significantly higher for Group 3 compared with Groups 1 & 2. The factor associated with PMV > 30 days was VAP (aOR: 19.53, 95% CI: 2.38–160.34, P = 0.01). Factors associated with non-surviving patients were 3rd degree PEM (aOR: 5.14, 95% CI: 1.57–16.88, P = 0.01), PIM3 score ≥14 (aOR: 6.75, 95% CI: 2.26–20.15, P < 0.001) and muscle relaxant usage (aOR: 5.58, 95% CI: 1.65–18.86, P = 0.01). Conclusion Extubation failure, tracheostomy rate, VAP rate, mortality rate by disease, PICU LOS and hospital LOS were significantly higher for PMV >30 days. Consequently, we suggest that a 30-day duration as a cut-point for PMV in PICUs might be more appropriate.

Project description:BackgroundAn increasing number of patients require prolonged mechanical ventilation (PMV) to survive recovery from critical care. It should be emphasized that PMV is a neglected disease in chest medicine. We investigated 6 years of clinical outcomes and long-term survival rates of patients who required PMV.MethodsWe analyzed retrospectively data from patients in respiratory care center (RCC) to investigate the main causes of respiratory failure leading patients to require PMV. We also studied the factors that influence the ventilator weaned rate, factors that influence the long-term ventilator dependence of patients who require PMV, as well as patients' hospital mortality and long-term survival rates.ResultsA total of 574 patients were admitted to RCC during the 6 years. Of these, 428 patients (74.6%) were older than 65 years. A total of 391 patients (68.1%) were successfully weaned from the ventilator while 83 patients (14.4%) were unsuccessfully weaned. A total of 95 patients (16.6%) died during RCC hospitalization. The most common cause of acute respiratory failure leading to patients requiring PMV was pneumonia. The factor that affected whether patients were successfully weaned from the ventilator was the cause of the respiratory failure that lead patients to require PMV. Our hospital mortality rate was 32.4%; the 1-year survival rate was 24.3%. There was a strong correlation between higher patient age and higher hospital mortality rate and poor 1-year survival rate. Patients with no comorbidity demonstrated good 1-year survival rates. Patients with four comorbidities and patients with end-stage renal disease requiring hemodialysis comorbidity showed poor 1-year survival rates.ConclusionsThe factor that affected whether patients were successfully weaned from the ventilator was the cause of the respiratory failure that lead patients to require PMV. Older patients, patients with renal failure requiring hemodialysis, and those with numerous comorbidities demonstrated poor long-term survival.
