OBJECTIVE: To analyze the level of sedation in intubated children as a risk factor for the development of subglottic stenosis (SGS). METHODS: All patients between 30 days and 5 years of age who required endotracheal intubation in the pediatric intensive care unit between 2013 and 2014 were included in this prospective study. They were monitored daily and COMFORT-B scores were obtained. Flexible fiber-optic laryngoscopy was performed within eight hours of extubation, and repeated seven to ten days later if the first examination showed moderate to severe laryngeal injuries...

BACKGROUND: Based on randomized trials, carotid endarterectomy (CEA) is the standard procedure for patients with a 50-99% symptomatic carotid stenosis and carefully selected patients with an asymptomatic high-grade carotid stenosis. Carotid artery stenting (CAS) is a technical alternative for patients with a high surgical risk or difficult anatomic conditions (e.g., recurrent stenosis). This study aims to provide an overview of anatomic factors associated with a higher risk of CEA complications...

Chondrodysplasia punctata is a group of congenital bone and cartilage disorders characterized by erratic calcification during development. Laryngeal and tracheal calcification and subsequent stenosis, while being reported in several cases of chondrodysplasia punctata, are not frequent findings and there are no proposed management techniques. We describe here a case of an infant with chondrodysplasia punctata associated to tracheal stenosis that was successfully treated with balloon dilation, and with long term follow-up...

Intubation is a routine intervention in the Neonatal Intensive Care Unit (NICU) for preterm neonates with respiratory distress, inadequate gag reflex, poor sucking and swallowing. Prolonged intubation in neonates can be done by nasal or oral route. Although naso-tracheal intubation may reduce movement of the tube, it may contribute to airway obstruction, possible hypoxia, and occlusion of the nasal aperture during a crucial period of development further contributing to laboured breathing. Being obligate nasal breathers, oro-tracheal route is the preferred method of intubation in premature infants as oral mucosa is less susceptible to damage than nasal mucosa...

Introduction Tracheostomy is the commonest surgical procedure in intensive care units (ICUs). It not only provides stable airway and facilitates pulmonary toilet and ventilator weaning, but also decreases the direct laryngeal injury of endotracheal intubation, and improves patient comfort and daily living activity. Objective The objective of this study is to assess the incidence, indications, timing, complications (early and late), and the outcome of tracheostomy on patients in the intensive care units (ICU) at a university hospital in a developing country...

We present a case of impassable subglottic stenosis scheduled for tracheal resection and reconstruction managed by establishing a supraglottic airway. Despite careful preoperative evaluation, the stenosis was localized higher than anticipated, rendering conventional intubation impossible. Laryngeal mask bridging to cross-field ventilation was feasible and jet ventilation and cardiopulmonary bypass were available as emergency strategies. Surgery and emergence went uneventful. Perioperative considerations are discussed in this report...

Epidermolysis bullosa refers to a clinically and genetically heterogeneous group of inherited mucocutaneous diseases. Laryngotracheal lesions are momentous regarding the risk of sudden airway obstruction. The traditional treatment is tracheostomy. This case report highlights the advantages of minimally invasive interventions. A successful combined endoscopic management of a life-threatening respiratory crisis is presented in a 4-year-old child. Combined commissure stenosis with supraglottic spread was treated by CO2 laser dissection and bilateral endoscopic arytenoid abduction lateropexy, supplemented with mitomycin C application...

OBJECTIVES: Repair of laryngotracheal stenosis with pronounced side-to-side narrowing and involvement of the glottis is challenging and usually requires laryngotracheal reconstruction with rib cartilage interpositions. This technique, as first described by Couraud, needs prolonged postoperative stabilization with Montgomery T-tubes, imposing significant morbidity and discomfort on patients. We describe our initial experience with a modified laryngotracheal reconstruction technique that avoids the need for prolonged postoperative stenting...
