A prospective controlled randomised study has been performed of 100 consecutive patients undergoing varicose vein surgery. One group underwent saphenofemoral flush ligation and multiple lower leg avulsions with the leg exsanguinated with a Rhys-Davies cuff, and ischaemia maintained with a pneumatic tourniquet. The other group underwent identical surgery but with a 30 degree head down tilt only. Blood loss was significantly less (13.5 +/- 12 ml vs 133 +/- 78 ml; P less than 0.01) and postoperative cosmesis was significantly improved in patients in the tourniquet group. Operating time was similar (27 +/- 11 min vs 30 +/- 13 min) in the two groups.
对100例连续接受静脉曲张手术的患者进行了一项前瞻性对照随机研究。一组患者接受大隐静脉股静脉高位结扎及多次小腿剥脱术,术中使用里斯 - 戴维斯袖带使下肢放血,并使用气动止血带维持缺血状态。另一组患者接受相同手术,但仅采用头低30度倾斜体位。止血带组患者的失血量显著减少(13.5±12毫升 vs 133±78毫升;P<0.01),术后美容效果显著改善。两组的手术时间相似(27±11分钟 vs 30±13分钟)。
