目的了解本院骨科膝关节手术用血情况,为临床合理用血提供依据。方法回顾性分析2015年上半年在本院行膝关节手术接受输血的181例患者的临床资料。分析成分血及自体血使用情况,及对输血相关因素如性别、血型、年龄、凝血指标和住院天数等进行统计学分析。结果 181例患者女性较多为141例,AB型患者最少,不同性别和血型与平均输血量比较,差异均无统计学意义(P>0.05)。平均输血量与手术类型和年龄有显著相关性(P<0.05),双膝置换较单膝手术用血量大,50-70岁年龄段平均输血量最大。备自体血患者输血后RBC、Hb和Hct值较输血前有所下降但均在正常值范围内。未输血浆患者术后凝血指标均正常,随着输血总量的增加,平均住院天数增多。结论年龄和手术类型与平均输血量有明显的相关性,我们应严格把握输血适应症,选择安全节约的用血方式。
Objective To understand the blood supply of orthopedic knee surgery in our hospital and provide evidence for clinically rational use of blood. Methods The clinical data of 181 patients undergoing knee surgery in our hospital during the first half of 2015 were retrospectively analyzed. Analysis of blood components and autologous blood use, and blood transfusion related factors such as gender, blood type, age, coagulation index and hospitalization days for statistical analysis. Results There were 141 females in 181 patients, the least in type AB patients. There was no significant difference between them (P> 0.05). The mean blood transfusion volume was significantly correlated with the type and age of the surgery (P <0.05). The mean amount of blood transfusions was greater in the 50-70 years than that in the knee surgery. RBC, Hb and Hct values in patients with autologous blood transfusion after blood transfusion decreased but were within the normal range. Patients without blood plasma coagulation indicators were normal, with the increase of total blood transfusion, the average number of days of hospitalization increased. Conclusion There is a significant correlation between age and type of surgery and average blood transfusion. We should strictly control the transfusion indications and choose a safe and economical way of using blood.
