Current view on diagnostic methods and risk factors of post-intubation laryngeal stenosis in pediatric patients

Laryngeal injury is a very common complication after intubation, especially in children. It carries a great economic burden for parents and the medical system and greatly disrupts the child’s physical and social development. Treatment of chronic post-intubation complications is time-consuming and resource-intensive and may end up unsuccessful even after many years. To prevent the development of laryngeal stenosis in children after intubation, careful evaluation of the risk factors leading to soft tissue scarring is necessary. Our goal was to analyze the literature on the incidence of post-intubation laryngeal injuries in children and the underlying risk factors. We reviewed the literature on post-intubation laryngeal complications available in the following databases: Clinicalkey, PubMed, PubMed Central, UptoDate, and Embase. According to the collected data, we categorized all factors into patientrelated and procedure-related. However, all risk factors have a low level of evidence, which requires additional studies in the future.
