Abstract:

 Objective To analyze the risk of perioperative complications in patients with lung cancer under different body mass index under general anesthesia. Methods A single?center retrospective study was performed in this study. The clinical data of 491 patients with lung lobectomy under general anesthesia were collected from October 2008 to October 2016, and the relationship between the complication and the patients with different BMI was analyzed. Results A total of 28 patients with very low body mass index（BMI<17）, 41 patients with low body mass index（17≤BMI<18.5）, 324 patients with normal body mass index （18.5≤BMI<24） Overweight （BMI≥24） patients were 98 patients. Compared with normal BMI patients, the risk of hypotension and arrhythmia was significantly higher in patients with very low body mass index（P<0.05）, and obese patients were more likely to develop hypoxia（P<0.05）. At the same time, the incidence of postoperative complications such as pulmonary infection was signifi-cantly higher in patients with very low body mass index（P<0.05）. Conclusion The incidence of compli-cations of general anesthesia in patients with very low body mass index is high, and it is necessary to strengthen intraoperative and postoperative management.

摘要：

目的 分析不同的体质指数肺癌患者全麻下肺切除术围手术期并发症发生的风险。方法 本研究采用单中心回顾性研究。收集我院2008年10月～2016年10月间共491例因肺癌在全麻下实施肺叶切除手术患者的临床资料，并分析其并发症与不同BMI患者之间的关系。结果 所有患者中，极低体质指数（BMI<17）患者共28人，低体质指数（17≤BMI<18.5）患者共41人，正常体质指数（18.5≤BMI<24）患者共324人，超重（BMI≥24）患者共98人。与正常体质指数患者比较，极低体质指数患者术中发生低血压和心律不齐的几率升高（P<0.05），而肥胖患者更易出现低氧情况（P<0.05）；同时，极低体质指数患者术后并发症如肺部感染的发生率高于其他组（P<0.05）。结论 极低体质指数患者全麻肺切除术并发症发生率高，需加强术中和术后管理。
