Abstract
Background:Airway obstruction manifested by the presence of stridor is a well-known complication
following extubation after patients have been on mechanical ventilation using invasive airway
device.
Objective:The objective of the study is to assess the incidence of post extubation stridor in pediatric
patients admitted to the two selected intensive care units, at Tikur Anbessa Specialized Hospital
and Menelik II Hospital, and the predictive factors associated with its occurrence.
Methodology:Prospective observational cross sectional study was conducted over an eight month span (from
September 2023 to April 2024), focusing on Patients aged 0-16years who had received invasive
mechanical ventilator support in the pediatric ICU and were later extubated. The study collected
and analyzed relevant data from two selected referral hospitals based on a literature review.
Result:A total of fifty seven patients were included in the study with median age of 2.5 years and
median duration of intubation was 3 days. The incidence of post extubation stridor in pediatric
intensive care unit in our study area was found to be 10.5%. Prolonged duration of intubation (p-
value=0.038) and multiple tube insertions (p-value= 0.047) were significantly associated with
this complication.
Conclusion:The study showed moderate frequency of post extubation stridor compared to previous studies.
Prolonged duration of intubation and presence of multiple tube insertions were found to be
predictive factors in our study. Awareness of the incidence as well as the associated factors for
pediatric stridor following extubation leads to timely identification and prompt management
which can improve patient outcome.
