摘要
目的研究影响初次全膝关节置换术(TKA)的围手术期失血、隐性失血和输血的危险因素。方法回顾分析由同一组医师手术的68例初次TKA患者，分析独立危险因素性别、止血带时间和体重指数与围手术期失血及输血量的关系。结果初次TKA围手术期失血男患比女患更明显，止血带时间、总手术时间和失血量正相关。体重指数与围手术期失血间没有明确关联。总的隐性失血量为总失血量的39%。结论性别、止血带时间及手术时间与初次TKA围手术期失血相关。输血量既与术前血红蛋白水平相关，也与术中失血量相关。血液动力学稳定的TKA术后患者，可以把血红蛋白80g/L作为输血临界值。
Abstract
Objective Carried out a retrospective study to determine the risk factors affecting the hidden blood loss, peri-operative blood loss and blood transfusion requirements in a primary total knee arthroplasty(TKA). Methods We included a total of 68 consecutive patients who underwent primary TKA by a single surgeon. The risk factors of blood loss and blood transfusion analysed were gender, tourniquet time and body mass index(BMI). Results There was significantly less peri-operative blood loss in females patients than in male. The BMI did not show any correlation with peri-operative blood loss. The amount of hidden blood loss in our series was 39%. The tourniquet time and the surgical time showed a positive correlation with peri-operative blood loss. Conclusions Our results indicate that tourniquet time and gender plays an important role in blood loss in TKA. The blood transfusion depends on both intra-operative blood loss and pre-operative haemoglobin value. The post-operative transfusion trigger can be brought to 80g/L in a haemodynamically stable patient.
