Tracheostomy In Pediatric Intensive Care Unit-Two Decades Of Experience

Objective: To study the profile, indications, related complications, and predictors of decannulation and mortality in patients who underwent tracheostomy in the pediatric intensive care unit (PICU).Methods: Retrospective analysis of prospectively collected data of tracheostomies was done on patients admitted at PICU. Demographics, primary diagnosis, indication of tracheostomy, and durations of endotracheal intubation, mechanical ventilation, and tracheostomy cannulation were recorded. The indication was recorded in one of the four categories-upper airway obstruction (UAO), central neurological impairment (CNI), prolonged mechanical ventilation, and peripheral neuromuscular disorders).Results: Two hundred ninety cases were analyzed. UAO (42%) and CNI (48.2%) were main indications in the halves of the study period, respectively. Decannulation was successful in 188 (64.8%) patients. Seventy-seven percentage UAO patients were decannulated successfully [OR (odds ratio); 95% CI (confidence interval), 2.647; 1.182-5.924, p = 0.018]. Age <1 year (0.378; 0.187-0.764; p = 0.007), nontraumatic, noninfectious central neurological diseases (0.398; 0.186-0.855; p = 0.018), and malignancy (0.078; 0.021-0.298; p <0.001), durations of posttracheostomy ventilation (0.937; 0.893-0.983; p = 0.008), and stay in the PICU (0.989; 0.979-0.999; p = 0.029) were predictors of unsuccessful decannulation. There were 91 (31.4%) deaths. Age <1 year (2.39 (1.13-5.05; p = 0.02), malignancy (17.55; 4.10-75.11; p <0.001), durations of posttracheostomy ventilation (1.06; 1.006-1.10; p = 0.028), and hospital stay (1.007; 1.0-1.013; p = 0.043) were independent predictors of mortality. Indication of UAO favored survivor (0.24; 0.09-0.57; p <0.001).Conclusion: The indications for tracheostomy in children had changed over the years. Infancy, primary diagnosis, length of posttracheostomy ventilation, and stay in the PICU and hospital were independent predictors of decannulation and mortality.
