Post-extubation stridor after prolonged intubation in the pediatric intensive care unit (PICU): A prospective observational cohort study
European Archives of Oto-Rhino-Laryngology May 07, 2020
Veder LL, Joosten KFM, Schlink K, et al. - Given that laryngeal damage may occur due to prolonged endotracheal intubation, with stridor being the most relevant clinical symptom, researchers investigated the incidence of post-extubation stridor as well as their clinical results among children within a tertiary referral center. They also explored contributing factors. Prospective enrollment of 150 children, aged 0–16 years, intubated for more than 24 h, was done until discharge of the hospital. The median duration of intubation was 4 days. The occurrence of stridor after extubation was reported in 28 patients (18.7%); 3 of them needed reintubation because of respiratory distress and persistence of stridor, for which a surgical intervention was necessary, was reported in 1 child. These findings show that although the reported incidence for post-extubation stridor was high, only few children required reintubation or surgical intervention because of post-extubation lesions. A significant increased risk of post-extubation stridor was observed in relation to the following factors: intubation on the scene, the use of cuffed tubes and young age. The opportunity to anticipate on the situation as well as to decrease laryngeal injury and its likely future outcomes is afforded by awareness of these factors.
