Diaphragmatic ultrasound-derived MV×DE: a novel predictor of postextubation adverse respiratory events in general anesthesia patients (observational study).

ABSTRACT:

Objective

This study explored the potential of diaphragmatic ultrasonography in the postanaesthesia care unit (PACU) for predicting postextubation adverse respiratory events (PAREs) in patients recovering from general anaesthesia.--.

Methods

This cohort study included 110 patients who underwent elective surgeries under general anaesthesia. During recovery before extubation, diaphragmatic function was monitored via ultrasound with pressure support ventilation on continuous positive airway pressure (PS/CPAP). Concurrent respiratory parameters (tidal volume, respiratory rate, and PEEP) were also recorded. Patients were categorized into PARE and nonadverse respiratory event groups based on postextubation outcomes. A composite metric, MV×DE, was calculated by multiplying minute v
