Prospective cohort study identifies risk factors for respiratory depression and its impact on postoperative pulmonary complications.

Respiratory depression was observed in 17.4% of patients, leading to a significantly increased risk of postoperative pulmonary complications.
Multivariate analysis identified age, ASA III classification, and preoperative lung disease as key independent risk factors for respiratory depression.
The study collected data from June 2022 to August 2023 at a tertiary care center, assessing patient outcomes based on respiratory depression status.
These findings highlight the importance of careful monitoring in the PACU to reduce the incidence of serious postoperative complications.
