Risk factor for prolonged post-anesthesia care unit stay in elderly patients after painless gastrointestinal endoscopy / 中华麻醉学杂志

ABSTRACT

Objective:To identify the risk factor for prolonged post-anesthesia care unit (PACU) stay in elderly patients after painless gastrointestinal endoscopy.Methods:The elderly patients received painless gastrointestinal endoscopy from March to June 2021 in our hospital were included in this study. The information such as preoperative interview, patient′s general condition, current and past medical history, intraoperative conditions, and conditions in the PACU was collected. Patients were divided into non-prolonged group (group N) and prolonged group (group D) based on whether PACU stay was prolonged, and the risk factors for prolonged PACU stay were identified by logistic regression analysis.Results:There were 257 patients in group D and 716 cases in group N, and the incidence of prolonged PACU stay was 26.4%. Compared with group N, the proportion of preoperative frailty, smoking, intraoperative hypotension, and ratio of hypotension, somnolence and dizziness in PACU were significantly increased in group D ( P<0.05). The results of logistic regression analysis showed that preoperative frailty, smoking, intraoperative hypotension, and hypotension, somnolence and dizziness in PACU were independent risk factors for prolonged PACU stay( P<0.05). Conclusions:Preoperative frailty, smoking, intraoperative hypotension, and hypotension, somnolence and dizziness are independent risk factors for prolonged PACU stay in elderly patients after painless gastrointestinal endoscopy.
