Abstract: Objective  To explore the application effect of enhanced recovery after surgery in perioperative period of elective cesarean section(C-section). 
Methods  A total of 220 patients undergoing elective C-section in our hospital were enrolled in this study. According to the random number table, 110 cases were divided into control group(n=110) and research group(n=100). The control group was treated with the traditional rehabilitation mode, while the research group was treated with the ERAS. The differences of postoperative pain, postoperative urination time, postoperative exhaust time, postoperative complications, time of off-bed activity, length of hospital stay and satisfaction were observed between two groups. 
Results  The pain of the two groups was relieved at 2 d after operation compared with that at 1 d after operation. The difference between time points was statistically significant(P＜0.05), while the difference between groups and time points between groups was not statistically significant(P＞0.05). The time of urination and the first time of anal exhaust in the research group were less than those in the control group(P＜0.05). The postoperative complications and hospitalization days of the research group were fewer than those of the control group(P＜0.05). The satisfaction of the research group was higher than that of the control group(P＜0.05). 
Conclusion  The application of ERAS in the perioperative period of elective C-section can ensure the removal of urinary tube and off-bed activity within 6 h after operation, early urination, promote the recovery of gastrointestinal function, reduce postoperative complications, accelerate postoperative recovery, and improve patient satisfaction. Therefore, it is worthy of clinical promotion.
