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.
