Abstract
Enhanced recovery after surgery (ERAS) has been accepted widely in the whole world. However, clinical effects of ERAS in China have not been systematically reported, and it is still unclear whether there is key component with the present ERAS program to secure enhanced recovery. Patients who were undergoing operations with ERAS program were included. All the perioperative information were collected via a website and a nomogram to predict postoperative complication was conducted. 950 subjects from 59 hospitals were included in this study. Illness of cardiovascular (22.6%) and endocrine system (11.1%) were the top two coexisted diseases preoperatively. The recovery time of ability of drinking water after surgery was 6 (4-8) h, and almost half of patients could do active exercises in bed within 6 h postoperatively. The overall incidence of complications within 1 month postoperatively was 11.1%. Preoperative creatinine and bilirubin, intraoperative maximum systolic blood pressure and NRS scores at rest at postoperative 3 days were independent risk factors for complications within 1 month postoperatively. However, minimally invasive surgery was associated with a decrease probability of the complications. This study firstly indicates preoperative hepatorenal function, intraoperative systolic blood pressure, minimally invasive surgery and postoperative pain control can independently influence the prognosis of surgical patients.
