Abstract: Objective　To explore the effects of ERAS (enhanced recovery after surgery) and routine interventions for elderly hip arthroplasty. Methods　From January 2019 to July 2020, 96 elderly patients who underwent elective hip replacement were randomly divided into control group and study group, 48 cases in each group. The control group received the routine interventions, while the study group received ERAS. Intervention outcomes were compared between the 2 groups. Results　The intraoperative blood loss in the study group was less than that in the control group, and the incision healing time and total length of hospitalization were less than that in the control group, with significant differences (P<0.05). However, there was no significant difference in operation duration between the two groups (P>0.05). There were no significant differences in pain score and hip function score between the study group and the control group before and 6 months after surgery (P>0.05). However, the pain score at 1 month and 3 months after surgery was lower than that of the control group, and the hip function score was higher than that of the control group, with significant differences (P<0.05). The complication rate in the study group was 6.25%, which was significantly lower than that in the control group (29.17%, P<0.05). Conclusion　ERAS can better reduce the pain symptoms and surgical complications, and promote the patient's fast rehabilitation. It is worthy of clinical application.
