Post-extubation stridor after prolonged intubation in the pediatric intensive care unit (PICU): a prospective observational cohort study.

Purpose: Prolonged endotracheal intubation may lead to laryngeal damage, with stridor being the most relevant clinical symptom. Our objective was to determine the incidence of post-extubation stridor and their clinical consequences in children within a tertiary referral center and to identify contributing factors.

Methods: 150 children, aged 0-16 years, intubated for more than 24 h were prospectively enrolled until discharge of the hospital.

Long-term quality of life in children after open airway surgery for laryngotracheal stenosis.

Objectives: The purpose of this study is to evaluate the long-term health related quality of life (HRQoL) in a cohort of children surgically treated for laryngotracheal stenosis (LTS).

Study Design: Prospective cohort study.

Methods: Parents of children between 4 and 18 years at follow-up completed the Child Health Questionnaire Parent Form (CHQ-PF50).

Acoustic simulation of a patient's obstructed airway.

This research focuses on the numerical simulation of stridor; a high pitched, abnormal noise, resulting from turbulent airflow and vibrating tissue through a partially obstructed airway. Characteristics of stridor noise are used by medical doctors as indication for location and size of the obstruction. The relation between type of stridor and the various diseases associated with airway obstruction is unclear; therefore, simply listening to stridor is an unreliable diagnostic tool.

Characteristics and surgical outcome of 98 infants and children surgically treated for a laryngotracheal stenosis after endotracheal intubation: excellent outcome for higher grades of stenosis after SS-LTR.

Introduction: To describe the characteristics and surgical outcome of 98 infants and children treated for an acquired laryngeal stenosis after intubation for respiratory support.

Material And Methods: We retrospectively reviewed our data from the last 18 years (1994-2013) concerning infants and children with an acquired laryngotracheal stenosis who were treated in our hospital with a laryngotracheal reconstruction or a cricotracheal resection. Outcome was defined by decannulation ratio.

Subglottic stenosis in Shwachman-Diamond syndrome - is there a link?

Clinically relevant cartilaginous subglottic stenosis was found in 2 patients with Shwachman-Diamond syndrome (SDS) for which tracheotomy was required in one case. Considering the pathogenesis of SDS, including deficient chondrogenesis, we hypothesise that subglottic stenosis may be a rare symptom of SDS. Otorhinolaryngologist and paediatricians should be aware of the risk of airway pathology in patients with SDS.
