To explore the predictive value of gastric antral cross-sectional area (CSA) in the occurrence of postoperative nausea and vomiting (PONV) by analysing the association between gastric antral CSA measured by ultrasound and frequency of PONV after laparoscopic cholecystectomy.
Observational study. Place and Duration of the Study: Department of Anaesthesiology, The First Hospital of Wannan Medical College, Yijishan Hospital of Wannan Medical College, from October 2021 to February 2022.
Gastric antral ultrasound (US) was performed in 266 patients undergoing laparoscopic cholecystectomy (LC) before anaesthesia induction, after it, and after surgery. The data obtained were used to evaluate the relationship between gastric antral CSA and PONV.
The gastric antral CSA in Semi-recumbent decubitus (SRD) position >398.85 mm2 (AUC=0.623) highly indicated the occurrence of PONV. In addition, the subject performance characteristic curve of a binary logistics retrospective model for predicting PONV (AUC=0.805) highly indicated the occurrence of PONV.
Gastric US assessment of gastric antral CSA might change the current assessment model of PONV risk. This study showed that the gastric antral CSA in the SRD position after anaesthesia induction and a binary logistics retrospective model could be used to predict the occurrence of PONV, which could be helpful to adjust intraoperative and postoperative interventions and accelerate the recovery of patients.

通过分析超声测量的胃窦横截面积（CSA）与腹腔镜胆囊切除术后恶心呕吐（PONV）发生频率之间的关联，探讨胃窦CSA对PONV发生的预测价值。
观察性研究。研究地点和时间：皖南医学院第一附属医院弋矶山医院麻醉科，2021年10月至2022年2月。
对266例行腹腔镜胆囊切除术（LC）的患者在麻醉诱导前、诱导后及术后进行胃窦超声（US）检查。所得数据用于评估胃窦CSA与PONV之间的关系。
半卧位时胃窦CSA>398.85 mm²（AUC=0.623）高度提示PONV的发生。此外，预测PONV的二元逻辑回归模型的受试者工作特征曲线（AUC=0.805）高度提示PONV的发生。
超声评估胃窦CSA可能会改变目前的PONV风险评估模式。本研究表明，麻醉诱导后半卧位时的胃窦CSA及二元逻辑回归模型可用于预测PONV的发生，这有助于调整术中及术后干预措施，加速患者康复。
