ABSTRACT

Introduction: extubation failure is a common condition in intensive care units. Despite the availability of diagnostic tests, the incidence of failure ranges from 3% to 30%, with extubation tests that do not achieve ideal sensitivity and specificity. Objective: the usefulness of the LUS protocol as a predictor of weaning from mechanical ventilation in ICU patients at UMAE 71 was valuated. Material and methods: in this retrospective, cross-sectional diagnostic test study, patients admitted to the adult ICU from April 1, 2023, to July 1, 2024, who required mechanical ventilation for at least 48 hours and at least 7 days, were included. Demographic variables and the LUS score obtained prior to extubation were collected. Results: a total of 198 patients were included: 99 males and 99 females. The mean age was 44 years. 49 had extubation failure, with a score of 16 ± 2 points. A total of 148 had successful extubation, with a LUS score of 10 ± 1.5. Conclusions: the sensitivity was 98%, the specificity was 99%, the positive predictive value was 98%, and the negative predictive value was 99%. This suggests that using the LUS protocol helps us choose the optimal time for extubation.
