人工全髋关节置换术及全膝关节置换术术后隐性失血的临床比较

Clinical comparison of postoperative hidden blood loss by artificial hip replacement and total knee arthro-plasty

目的探究人工全髋关节置换术及全膝关节置换术术后隐形失血的情况。方法选取周口市中心医院2012年6月至2014年9月收治的60例接受人工全髋关节置换术治疗的患者为实验组，另选择同期来院行人工全膝关节置换术的72例患者为对照组，依据Gmss方程，并结合患者体质量、身高、手术前后红细胞压积．行隐性失血计算。结果实验组隐性失血量为（482．1±42．7）ml，明显低于对照组的（776．1±84．8）ml（P〈0．05）；而未应用引流血回输者与应用引流血回输者隐性失血比较差异未见统计学意义（P〉0．05），组内肥胖者与非肥胖者隐性失血量比较差异未见统计学意义（P〉0．05）。结论人工全膝关节置换术后隐性失血量明显高于人工全髋关节置换术，应用引流血回输无法满足机体体循环恢复需要，应及时行血容量补充。

Objective To investigate the postoperative hidden blood loss by artificial total hip replacement and to- tal knee arthroplasty. Methods Sixty patients accepted total hip arthroplasty from June 2012 to September 2014 were se- lected as the experiment group, the other 72 patients accepted total knee arthroplasty were selected as the control group, ac- cording to Gmss equation, calculated hidden blood loss combination of the patients weight, height, the red blood cell pres- sure before and after operation. Results In experiment group, the hidden blood loss [ （482. 1 ± 42. 7）ml ] was significant- ly lower than in that incontrol group[ （776. 1 ±84. 8）ml] （P 〈0. 05）, but not use of drainage blood transfusion and appli- cation of drainage blood transfusion hidden blood loss had no significant differences （P 〉 0. 05）. The hidden blood loss of obese and non obese in the group had no significant difference （P 〉 0. 05）. Conclusions The hidden blood loss after total knee arthroplasty was significantly higher than that after artificial hip replacement, the application of drainage blood transfu- sion cannot meet the body circulation recovery needs, should be timely supplement blood capacity.
