Value of intraoperative Surgical Apgar Score in predicting postoperative delirium in patients undergoing pancreaticoduodenectomy / 中华麻醉学杂志

ABSTRACT

Clinical data of patients underwent pancreaticoduodenectomy due to malignant ampullary tumors from January 2013 and December 2016 in our hospital with full access to medical records were collected,and 144 patients were enrolled in total.Surgical Apgar Score (SAS) was calculated based on the intraoperative lowest mean arterial pressure,lowest heart rate and blood loss.The patients were divided into 2 groups depending on whether postoperative delirium developed or not within 7 days after surgery.The receiver operating characteristic curve of SAS in predicting postoperative delirium was drawn.The area under the curve,optimal cut-off value and sensitivity and specificity were calculated.Thirty-six patients developed postoperative delirium,and the incidence was 25.0％.The area under the curve of SAS in predicting postoperative delirium was 0.86 (95％ confidence interval 0.79-0.91).The optimal cut-off value was 6 with a sensitivity of 86％ and a specificity of 83％.In conclusion,intraoperative SAS can predict the development of postoperative delirium in patients undergoing pancreaticoduodenectomy.
