Abstract：Objective To investigate the impact of early functional exercise on perioperative hidden blood loss(HBL)in patients undergoing total hip arthroplasty(THA).Methods A total of 142 elderly patients with femoral neck fractures who underwent THA at author'hospital were retrospectively analyzed.These patients were categorized into lit-tle functional exercise group and normal functional exercise group based on the intensity of their functional exercise.In the normal functional exercise group,82 patients completed normal intensity or more than normal active function exercise un-der the guidance of rehabilitation doctors,in the little functional exercise group,60 patients completed the active exercise intensity less than half of the normal intensity.The total blood loss,total blood loss/original blood volume,HBL vol-ume,HBL volume/total blood loss were calculated according to the blood indexes of the patients at admission and the 5 th day after surgery.The impact of early functional exercise intensity on perioperative blood loss and HBL after THA was analyzed.Results There were no significant differences in general information at admission between the two groups(P＞0.05).The total blood loss,total blood loss/original blood volume,HBL volume,HBL volume/total blood loss and the proportion of high HBL in the normal functional exercise group were significantly lower than those in the little functional exercise group(all P＜0.05).Conclusion Early functional exercise after THA can effectively reduce the amount of peri-operative HBL of THA patients,and has little effect on postoperative overt bleeding and wound healing.
