Analysis of postoperative nausea and vomiting in patients with lung cancer undergoing thoracoscopic surgery under general anesthesia and its influencing factors: a observational study

Abstract

ObjectiveTo investigate the current situation and influencing factors of postoperative nausea and vomiting (PONV) in lung cancer patients undergoing thoracoscopic surgery under general anesthesia, providing a reference for developing targeted PONV prevention and management strategies.MethodsUsing a consecutive sampling method, 200 lung cancer patients who underwent their first thoracoscopic surgery under general anesthesia between November 18, 2021, and March 1, 2022, at a tertiary class A cancer hospital in Liaoning Province, China, were selected. The occurrence of PONV within 24 h post-operation was assessed using WHO Postoperative Nausea and Vomiting Rating Criteria. Patient general information, surgical and medication data were systematically collected to analyze the independent influencing factors of PONV.ResultsAmong the 200 patients undergoing thoracoscopic lung cancer surgery under general anesthesia, 75 (37.5%) experienced PONV. Logistic regression analysis indicated that being female, having a history of motion sickness, and a history of PONV were independent risk factors for the occurrence of PONV in these patients. Long-acting antiemetics such as penehyclidine hydrochloride and methylprednisolone were protective factors against PONV.ConclusionThe incidence of PONV in patients undergoing thoracoscopic lung cancer surgery under general anesthesia is relatively high. Nursing staff should focus on female patients and those with a history of motion sickness and PONV. Comprehensive preoperative assessments should be conducted, exploring multimodal analgesia and applying integrated prevention measures to reduce the occurrence of PONV and promote the rapid recovery of patients.
