简介
Rationale: A new classification of patients based on the duration of liberation of mechanical ventilation has been proposed.
Objectives: To analyze outcomes based on the new weaning classification in a cohort of mechanically ventilated patients.
Methods: Secondary analysis included 2,714 patients who were weaned and underwent scheduled extubation from a cohort of 4,968 adult patients mechanically ventilated for more than 12 hours.
Measurements and Main Results: Patients were classified according to a new weaning classification: 1,502 patients (55%) as simple weaning, 1,058 patients (39%) as difficult weaning, and 154 (6%) as prolonged weaning. Variables associated with prolonged weaning (>7 d) were: severity at admission (odds ratio [OR] per unit of Simplified Acute Physiology Score II, 1.01; 95% confidence interval [CI], 1.001–1.02), duration of mechanical ventilation before first attempt of weaning …
