Abstract: [Abstract] Objective：To investigate the application of the concept of fast track surgery in the perioperative period of total hip arthroplasty.Methods：100 cases of total hip arthroplasty in our hospital were retrospectively analyzed.The patients were divided into observation group and control group，50 cases in each group，according to the perioperative intervention measures.The control group received routine intervention，and the observation group adopted enhanced recovery after surgery intervention mode on the basis of the control group.The blood loss and blood transfusion were compared between the 2 groups.The hip joint function，pain and selfcare ability of the 2 groups were detected and compared before and 3 months after operation.The hemorrheology indexes of the 2 groups were detected and compared before and 7 d after operation.The incidence of postoperative complications and nursing satisfaction in the 2 groups were statistically analysed.Results：Compared with the control group，the nursing satisfaction of the observation group was significantly higher（P<0.05）.The total blood loss，blood transfusion rate，the 1st d hemoglobin reduction of the observation group decreased significantly（P<0.05），the time of ambulation and the time of postoperative hospitalization of the observation group shortened significantly（P<0.05）.The daily activity and gait，joint activity and Harris total scores of the 2 groups after 3 months operation were significantly higher than those before the operation，the scores of pain and joint deformity were significantly lower than those before operation，the score of Visual analogue scale（VAS）in the 2 groups after 3 months operation was significantly lower than that before the operation，the Barthel index was significantly higher than that before the operation，the plasma levels of Ddimer in 7d of the 2 group were significantly higher than those before the operation，there were significant differences between the two groups in the above indexes（P<0.05）.The high viscosity of whole blood，low shear viscosity，blood sedimentation and plasma viscosity of the observation group after 7 d operation were significantly lower than those before the operation，and that were significantly lower than those in the control group（P<0.05）.There was no significant difference in the incidence of complications between the two groups（P>0.05）.Conclusion：The fast track surgery intervention model for patients with total hip arthroplasty can effectively improve hip joint function and selfcare ability，help to speed up the blood flow speed and reduce the pain of the body.
