摘要
目的通过计算人工髋关节置换术和人工膝关节置换术隐性失血量，分析其相关的危险因素，并探讨其发生机制。方法2008年7—11月行人工关节置换术38例，年龄（65．11±13．51）岁，其中人工髋关节置换术25例，人工膝关节置换术13例。根据身高、体质指数和手术前后的红细胞压积计算总失血量、显性失血量及隐性失血量及隐性失血率，并分析患者的年龄、体质指数、不同性别以及不同手术部位对隐性失血的影响。结果人工关节置换术实际总失血量为（1563．52±693．10）ml，隐性失血量为（538．70±529．77）ml，隐性失血率均值为33％。年龄与隐性失血量有明显相关性（P〈0．05）。体质指数与隐性失血量以及隐性失血率无明显相关性（P〉0．05）。男性和女性患者隐性失血量虽差异无统计学意义（P〉0．05），但女性患者隐性失血率要明显高于男性患者（P〈0．05）。考虑到年龄和性别的影响，对人工髋关节置换术和人工膝关节置换术患者的年龄和性别配对后比较，其隐性失血率比较差异有统计学意义（P〈0．05）。结论高龄、女性都是人工关节置换术隐性失血的危险因素；人工髋关节置换术的隐性失血率高于人工膝关节置换术。
Objective To calculate the volume and to study the correlated risk factors of hidden blood loss after artificial hip or knee joint replacement. Methods From July to November in 2008, 38 patients with age of （65.11 ± 13.51 ） years old were treated with artificial hip or knee joint replacement, and were divided by age into four groups. Using Gross formula, total blood loss was calculated depending on height, weight and pre- and post-operation hematoerit, and the hidden blood loss was acquired by subtracting the visible ＇blood loss from the total blood loss. The correlation between age, body mass index （BMI）, gender and hidden blood blood loss was observed. Differences of hidden blood loss of artificial hip or knee joint replacement were compared. Results The total blood loss of all arthroplasties was （ 1563.52 ± 693.10 ） ml, and the hidden blood loss was （538.70 ± 529.77） ml,the percentage of hidden bloocl loss was 33%. The hidden blood loss was inversely related to age （P 〈 0.05 ）. There was no correlation between BMI and hidden blood loss （P 〉 0.05）. The percentage of hidden blood loss in total blood loss in woman was significantly higher than that in man. With age and gender paired, the percentage of hidden blood loss in total blood loss in artificial hip joint replacement was significantly higher than that in artificial knee joint replacement （P 〈 0.05 ）. Conclusions Both of age and gender are risk factors influencing hidden blood loss after artificial hip or knee joint replacement. And eompared with artificial knee joint replacement, the percentage of hiddenblood los in artificial hip joint replacement is higher.
