文题释义:
隐性失血:髋关节和膝关节置换后,患者血红蛋白下降较为明显,而其下降程度与可观测到的显性失血量明显不符。隐性失血在关节置换后贫血的原因中占重要比例,但对于隐性失血的发生机制,目前尚不明确。
股骨髁间截骨:关于全膝关节置换假体类型,因不同类型假体的设计理念,决定了其截骨方式及是否需要股骨髁间截骨,同时假体对截骨面的覆盖程度也有差异。
 
摘要
背景:隐性失血是全膝关节置换后最重要的并发症之一,但目前对其发生机制及影响因素的了解尚不明确。
目的:分析单侧初次人工全膝关节置换后隐性失血的相关影响因素。
方法:回顾分析2014年4至9月接受单侧初次全膝关节置换的病历资料235例,男38例,女197例;年龄48-82岁,平均66岁。根据Gross的方法计算隐性失血量。分析性别、年龄、身高、体质量、体质量指数、麻醉方式、氨甲环酸使用情况、置换后抗凝方式、假体类型、止血带使用时间、置换前凝血功能等因素对全膝关节置换后隐性失血、出血的影响。

结果与结论:①男性和女性患者的置换后隐性失血量和总失血量相比,差异有显著性意义(P < 0.01);使用、未使用氨甲环酸组的隐性失血量、总失血量比较,差异有显著性意义(P < 0.05,< 0.01);②多重线性回归分析结果表明,患者置换前血红蛋白水平、身高是影响全膝关节置换后失血的重要因素。而隐性失血量、置换后总失血量与年龄、体质量指数、麻醉方式、置换后抗凝方式、假体类型、止血带使用时间及置换前凝血功能等无明显相关性;③结果提示,性别及氨甲环酸使用是全膝关节置换后隐性失血量和总失血量的影响因素,而年龄、体质量指数、麻醉方式、置换后抗凝方式、假体类型、止血带使用时间、置换前凝血功能对全膝关节置换后隐性失血影响不大。

Abstract:

BACKGROUND: Hidden blood loss is one of most important complications after total knee arthroplasty, but the mechanism and influential factors are not yet clear.

OBJECTIVE: To analyze the relative influential factors for hidden blood loss in primary unilateral total knee arthroplasty.
METHODS: Data of 235 patients who had undergone primary unilateral total knee arthroplasty from April to September 2014 were retrospectively studied. There were 38 males and 197 females aged from 48 to 82 years old with a mean age of 66 years. The Gross formula was used to calculate the amount of hidden blood loss. The effects of gender, age, height, body weight, body mass index, anesthesia method, administration of tranexamic acid, postoperative anticoagulation method, type of prosthesis, tourniquet time and pre-operative coagulation function on the postoperative hidden blood loss and total blood loss after total knee arthroplasty were analyzed.
RESULTS AND CONCLUSION: (1) Significant differences in hidden blood loss and total blood loss after total knee arthroplasty were detected between male and female patients (P < 0.01). Significant differences in hidden blood loss and total blood loss were found between tranexamic acid and non-tranexamic acid groups (P < 0.05, P < 0.01). (2) Multivariate linear regression analysis showed that preoperative hemoglobin level and height were important factors influencing the blood loss after arthroplasty. Hidden blood loss and total blood loss were not correlated with age, body mass index, anesthesia method, postoperative anticoagulation method, type of prosthesis, tourniquet time and preoperative coagulation function. (3) Results indicate that gender and administration of tranexamic acid affect hidden blood loss and total blood loss after total knee arthroplasty. However, age, body mass index, anesthesia method, postoperative anticoagulation method, type of prosthesis, tourniquet time and preoperative coagulation function do not greatly affect hidden blood loss.
