Twenty patients who underwent total hip arthroplasty were randomly allocated to have surgery through a mini incision of < or = 8 cm (mini-incision surgery [MIS] group, n = 10) or a standard incision of 14 cm (standard group, n = 10). A laser Doppler flowmeter was used to measure the intraoperative blood flow of the skin. The measurements were performed at 2 regions, specifically, anterior and posterior regions across the middle points of skin incision. The measurements were taken before making the incision and after implantation. As a control, the skin blood flow over the anterior superior iliac spine was measured. After implantation, mean skin blood flows at both regions in the MIS group were significantly decreased by 32% and 33%. However, the corresponding flows in standard group and control regions were constant during operation.
20例行全髋关节置换术的患者被随机分为两组，一组通过小于或等于8厘米的小切口进行手术（小切口手术[MIS]组，n = 10），另一组通过14厘米的标准切口进行手术（标准组，n = 10）。使用激光多普勒血流仪测量术中皮肤血流。测量在两个区域进行，具体为横跨皮肤切口中点的前部和后部区域。测量在切开前和植入后进行。作为对照，测量了髂前上棘上方的皮肤血流。植入后，MIS组两个区域的平均皮肤血流均显著降低了32%和33%。然而，标准组和对照区域的相应血流在手术过程中保持恒定。
