Incidence of hypoxemia in a post-anesthesia care unit and relevant risk factors

Abstract

Abstract: Objective To investigate the incidence and potential risk factors of postoperative hypoxemia in a post-anesthesia care unit (PACU). Methods The retrospective cohort assessed 14 604 postoperative patients who were admitted to PACU in a period of one year. Clinical data were collected, the incidence and potential risk factors for postoperative hypoxemia were statistically analyzed. Results The incidence of hypoxemia was 2.79%. Multiple regression analysis indicated that the risk factors were age (≥65-year old), body mass index (BMI≥25), American Society of Anesthesiologists (ASA ≥Ⅱ), limb surgery, and thoracic surgery. Conclusions Hypoxemia is common in postoperative patients in PACU. Age, BMI, ASA classification, and surgical site are associated with postoperative hypoxemia. Doctors should pay attention and give timely treatment to high-risk patients to prevent hypoxemia in PACU.

Key words: hypoxemia, pulse oxygen saturation, post-anesthesia care unit
