Objective  To analyze the effect of enhanced recovery after surgery (ERAS) model on prognosis of elderly patients with femoral neck fracture undergoing artificial femoral head replacement during perioperative period.

  Methods  A total of 118 elderly patients who underwent artificial femoral head replacement for femoral neck fracture were selected as research objects. They were randomly divided into control group (n=59) and experimental group (n=59). Routine surgical evaluation and preoperative preparation were performed in the control group, while ERAS mode intervention was performed in the experimental group during perioperative period. Perioperative indicators and postoperative complications were compared between the two groups. Visual Analogue Scale (VAS), Harris Hip Function Scale and European Five-dimension Health Scale (EQ-5D) were used to evaluate the pain degree, hip function at 1 month and 3 months after operation as well as quality of life.

  Results  The operation rate within 48 h in the experimental group was significantly higher, the blood transfusion rate and hospitalization cost were significantly lower, and the postoperative feeding time, bed-free activity time and hospitalization time were significantly shorter than those in the control group (P < 0.05). Three days after surgery, VAS score of the experimental group was significantly lower than that of the control group (P < 0.05). One month after surgery, Harris score of the experimental group was significantly higher than that of the control group (P < 0.05). The total incidence of complications in the experimental group was significantly lower than that in the control group (P < 0.05).

  Conclusion  ERAS model has a good effect in artificial femoral head replacement for elderly patients with femoral neck fracture, which can reduce the incidence of postoperative complications and effectively promote postoperative recovery of patients.
