Active clinical trials for "Laryngeal Edema"

In ICU, ventilatory weaning failure is common, accounting for up to 25% of extubations. These failures are largely due to swallowing disorders and laryngeal edema. Edema prevalence in ICU varies between 4 and 37%. Post-extubation stridor is a clinical sign of upper airway obstruction and may require urgent reintubation, which is associated with increased patient length of stay, morbidity and mortality. Identifying patients at risk is critical, and the need for reliable tools to predict the occurence of laryngeal edema is still relevant.

This randomized controlled multi-centre trial in children from birth up to < 5 years of age aims to demonstrate equivalence as to the major outcome of post-extubation airway injury (stridor) comparing uncuffed tracheal tubes to current tracheal tubes with modern high volume - low pressure cuff combined with a cuff pressure release valve.

Introduction: Endotracheal intubation and mechanical ventilation are lifesaving interventions that are commonly done in the intensive care unit (ICU). The act of intubating someone can cause laryngeal edema (LE) that, if extensive enough, can cause airway obstruction after a patient is extubated. To date, the only test that is available to predict this complication is the cuff leak test (CLT). However, its diagnostic accuracy is uncertain as there have been no randomized controlled trials (RCT) examining this. The Cuff leak and airway Obstruction in Mechanically ventilated ICU patients (COMIC) Randomized Control Trial will be done to examine the impact of CLT on postextubation stridor and reintubation. Subsequently, describing the diagnostic accuracy of this test. Methods: This will be a multi-center centered, pragmatic, double blinded RCT. Mechanically ventilated patients in the ICU, who are deemed ready to be extubated will be included. All patients will have a CLT done prior to extubation. The results of the CLT in the intervention arm will be communicated to the treating physician, and decision to extubate will be left to the treating team, while the results of the CLT for patients in the control arm will not be communicated to the treating physician, and the patient will be extubated, regardless of the result of the CLT. Objective: This is a pilot trial to assess feasibility of conducting a powered RCT. Feasibility outcomes include: consent rate, recruitment rate, and protocol adherence. Clinical outcomes will include postextubation stridor, reintubation, emergency surgical airway, ICU mortality, in hospital mortality, duration of mechanical ventilation, and ICU length of stay in days.

Tracheal intubation is a frequent procedure in intensive care units (ICU). Post-extubation laryngeal edema is a frequent complication with potential morbidity and mortality, and may lead to urgent tracheal re-intubation. Corticosteroids have been proposed to reduce the incidence of post-extubation laryngeal edema. A few clinical studies have been conducted in adult ICU patients and have led to discrepant results. These discrepancies may be related to the time lag separating the administration of the corticosteroids and the planned extubation. Accordingly, we tested the hypothesis that pretreatment with corticosteroids initiated 12 hours before a planned extubation may efficiently prevent the occurrence of postextubation laryngeal edema in critically-ill adults who have been mechanically ventilated for more than 36 hours in the ICU.

For patient in intensive care unit, extubation failure is defined as the necessity of early reintubation after scheduled extubation, with Increased morbidity and mortality, so it seems important to quickly identify patients with high risk of post-extubation acute respiratory failure. Major post-extubation laryngeal edema is one of extubation failure causes, and its incidence vary in literature from 4 to 37%. We can't currently predict arising of a major post-extubation laryngeal edema. However, a recent pilot study showed that laryngeal ultrasonography could help to identify patients with high risk of post-extubation stridor, measuring ultrasonic leak volume and cuff-deflated air-column width, of which we propose to assess diagnostic performance.
