不同体位引流对膝关节置换术后血液相关指标的影响

THE EFFECT OF DIFFERENT POSTURAL DRAINAGE ON PATIENT'S BLOOD INDEXES AFTER TOTAL KNEE ARTHROPLASTY

目的探讨膝关节置换术后关节不同体位引流对患者血液相关指标的影响。方法选择膝关节手术置换患者80例,按随机数字表分为两组,其中40例为伸直引流组,40例为屈曲引流组。采集80例患者的术前和术后拔除引流管后的血常规中红细胞、血红蛋白量及引流量进行方差分析比较。结果伸直体位与屈曲体位术前红细胞与术后红细胞差异有统计学意义,P<0.05;伸直体位与屈曲体位创腔引流量比较,P<0.05,差异有统计学意义;两组术前血红蛋白与术后血红蛋白比较,P>0.05,差异无统计学意义。结论膝关节置换术后不同体位引流能对患者术前和术后血液中的红细胞及创腔引流量有影响。

Objective To explore the effect of different postural drainage on patient＇s blood indexes after total knee arthroplasty（TKA）.Methods 80 cases of TKA were randomly and evenly divided into the straight drainage group and the buckling drainage group.Red blood cell count,the level of hemoglobin and the volume of drainage before and after operations were compared through variance analysis.Results The pre-operative and post-operative red blood cell counts showed significant difference in both groups（P 0.05）and the volume of drainage in the straight drainage group and the buckling drainage group showed significant difference（P 0.05）.The pre-operative and post-operative levels of hemoglobin in both groups showed no significant difference（P 0.05）.Conclusion Different postural drainage after TKA can produce effect on the red blood cell counts and the volume of drainage.
