Abstract:
Objective To assess the accuracy of ultrasonographic measurement of gastric fluid volume in predicting the occurrence of nausea and vomiting during and after emergency cesarean section.Methods Seventyseven ASA Ⅰ-Ⅲ patients aged 18-35 yr weighing 66-87 kg undergoing emergency cesarean section were divided into 3 groups according to the preoperative gastric fluid volume:group A ≤ 0.4 ml/kg (n =21); group B 0.4-0.8ml/kg (n =34) and group C > 0.8 ml/kg (n =22).Gastric fluid volume was calculated by Bouvet regression equation,based on antral area of the stomach measured with M-Turbo ultrasonography system (Somo Site Co.USA).Cesarean section was performed under combined spinal-epidural anesthesia with 0.4% ropivacaine.BP,HR and SpO2 were measured and recorded after entering the operating room,at skin incision and at the end of operation.The occurrence of nausea and vomiting was recorded during operation and within 1 h after operation.Results There was no significant difference in hemodynamic variables among the 3 groups.The incidence of nausea was comparable among the 3 groups:33% in group A,35% in group B and 46% in group C,while the incidence of vomiting was significantly higher in group C (46%) than in group A (10%) and group B (15%).Conclusion The incidence of vomiting is significantly higher during and within 1 h after emergency cesarean section in patients with preoperative gastric fluid volume > 0.8 ml/kg,but the incidence of nausea is not related to preoperative gastric fluid volume.
