Postintubation airway injury in the pediatric intensive care unit.

INTRODUCTION AND

OBJECTIVES

Airway injury caused by endotracheal intubation (ETI) is a common event in children who require ETI in the pediatric intensive care unit (PICU). The main aim of our study was to determine the incidence and the predisposing factors for the development of airway injury in PICU patients who need ETI. Secondary objectives were to evaluate the reasons for the request of airway endoscopy examination and the tracheostomy rate in this population.

MATERIALS AND

METHODS

A retrospective, observational, descriptive study was conducted evaluating 1854 patients who were intubated in the PICU of a tertiary-care center between May 2015 and April 2019.

RESULTS

The mean age of all intubated patients was 35.6 months and of those who required endoscopy 27.3 months (p = 0.04). Mean length of intubation was 7.2 days for all intubated patients and 23.5 days for those who required endoscopy (p = 0.0001). Extubation failure and stridor were significantly associated with the finding of airway injury (p = 0.0001 and p = 0.0006, respectively).

CONCLUSIONS

The incidence rate of ETI-related injury was 3%. Age younger than 27 months and intubation for more than 7 days were predisposing factors for the development of injury. The main indications for endoscopy were extubation failure and stridor, both related to the presence of injury. Tracheostomy rate in the PICU was 3.34%.
