全膝关节置换术后隐性失血的研究进展

Progress on recessive blood loss after total knee arthroplasty

全膝关节置换术后患者血红蛋白的下降程度与观察到的出血明显不符,这是由于隐性失血存在的缘故。隐性失血影响患者伤口的愈合,增加了感染的机会,延长了康复锻炼的时间,严重影响术后疗效。因此,有效地预防隐性失血就显得格外重要。本文分析了性别、年龄、身高与体重、止血带、手术时间与手术创伤、术后抗凝、单双膝置换、自体血回输等因素对隐性失血的影响,为全膝关节置换术隐性失血的预防提供一定的帮助。

After total knee arthroplasty, the hemoglobin descending level is not in accord with blood loss volume because of recessive blood loss. Recessive blood loss will delay wound healing,increase infected opportunity,prolong rehabilitation exercise time, effect clinical outcome, so prevention of recessive blood loss is very important. This review is about the effect of gender, age, height and weight, tourniquet, operative time and operative trauma, postoperative anticoagulation, unilateral or bilateral total knee arthroplasty, autoblood reinfusion on the recessive blood loss, which maybe is helpful for the prevention of recessive blood in total knee arthroplasty.
