Objective To explore the effect of operative positions during bariatric surgery on postoperative nausea and vomiting(PONV) .Methods The patients with obesity who underwent laparoscopic sleeve gastrectomy (LSG) in the hospital from June 2020 to February 2022 were divided into two groups and analyzed retrospectively. The multivariable logistic regression analyses and T test were used to study the influence for operative positions on PONV.Results There were 15 cases of PONV in the prone split-leg position group, with an incidence rate of 50%, and 11 cases of PONV in the supine position group, with an incidence rate of 36.7%(P = 0.297). The operation time in the prone split-leg position group was 168.23 ± 46.24 min and the anesthesia recovery time was 55.03 ± 21.392 min. The operation time in the supine position was 140.60 ± 32.256 min and the anesthesia recovery time was 44.60 ± 13.307 min. There were significant differences between the two groups(P༜0.05). Multivariable analysis showed that the operative positions was not an independent risk factor for PONV, with an OR of 1.192 ( 95%CI: 0.376–3.778, P = 0.766).Conclusions This study showed that the operative positions may affect the PONV. Although, the difference in the incidence of PONV was not significant. The operative positions should be carefully selected for the patients with obesity before surgery.
