Predictors and Associations of Prolonged Tracheostomy in Pediatric Cardiac Surgical Patients

Abstract

Objectives: To describe the predictors and associations of prolonged tracheostomy duration in pediatric cardiac surgical patients. Method: Prospective study. All pediatric patients below 10 years of age who underwent tracheostomy after cardiac surgery from January 2019 to December 2019, were subdivided into short and long groups according to the tracheostomy duration during the intrahospital stay if more than 21 days. Different variables were compared. Results:1084 pediatric patients who underwent cardiac surgery during study period, 41 (3.7%) received tracheostomy. LT group was associated with univentricular repair (p=0.03) and sepsis (p=0.04), longer days of ventilation (p=0.0005), higher number of extubation trials (p=0.02), higher accidental tracheostomy tube dislodgement (p=0.048), ventilator-associated pneumonia (p=0.013), more days of feed interruption (p=0.0089), higher days of hospital stay (p=0.0001) and intensive care unit stay (p=0.0001). ST was associated with significantly higher anticipated longer duration of ventilation and earlier liberation from the ventilator as an indication for tracheostomy than LT (p=0.02). Conclusions: Univentricular repair, sepsis, longer mechanical ventilation, longer duration of intensive care unit and hospital stay, a higher number of extubation trials, higher number of accidental tracheostomy tube dislodgement, ventilator-associated pneumonia, higher days of feed interruption were found to be significant associations with a long duration tracheostomy.
