摘要
背景:隐性失血在全髋关节置换围手术期失血量中占较大比例,可严重影响关节功能的恢复,目前其具体影响因素及机制尚不明确。目的:通过对初次全髋关节置换患者的失血情况评价置换后隐性失血的相关影响因素,并分析隐性失血量与患者预后的相关性。方法:回顾性分析2011年4月至2013年4月110例在柳州市工人医院接受初次全髋关节置换患者的临床资料,根据ward和Gross的方法计算隐性失血量,分析性别、年龄、体质量指数、假体类型、内科疾病、不同病因等对置换后隐性失血的影响。并按隐性失血量分为高失血组(≥480 m L)和低失血组(<480 m L),置换后随访1年,采用Harris髋关节评分系统评估两组患者髋关节功能恢复情况,并对隐性出血量与关节功能恢复效果的相关性进行Pearson相关性分析。结果与结论:接受初次全髋关节置换后患者总失血量为(1 340±367)m L,隐性失血量为(748±324)m L,占总量的53.7%。假体类型、内科疾病、不同病因与全髋关节置换后隐性失血量有显著相关性(P<0.05),性别、年龄、体质量指数、手术时间与全髋关节置换后隐性失血量无显著相关性(P>0.05)。隐性失血量和置换后功能恢复有相关性(P=0.046)。提示假体类型、内科疾病、不同病因是全髋关节置换后隐性失血量的主要影响因素,隐性失血量对患者置换后关节功能恢复有一定影响。
BACKGROUND：The hidden blood loss, accounted for a fairly large proportion of perioperative blood loss in total hip replacement, can seriously affect the recovery of postoperative joint function, but the specific influential factors and mechanisms remain unknown at present. OBJECTIVE：To evaluate the relative influential factors for hidden blood loss after primary total hip arthroplasty by the blood loss condition, and to analyze the association between hidden blood loss and prognosis. METHODS：Clinical data of 110 patients who underwent primary total hip arthroplasty in the Liuzhou Worker’s Hospital between April 2011 and April 2013 were retrospectively analyzed. The hidden blood loss was calculated according to Ward and Gross formula. The effects of patient’s gender, age, body mass index, type of prosthesis, presence of internal diseases, and different causes of a disease on hidden blood loss after arthroplasty were analyzed. The patients were divided into the high blood loss group （≥ 480 mL） and the low blood loss group （0.05）. The hidden blood loss was correlated with postoperative functional recovery （P=0.046）. Results indicated that type of prosthesis, presence of internal diseases, and different causes of a disease are main influential factors for hidden blood loss after total hip arthroplasty. The hidden blood loss has some influence on the recovery of postoperative joint function.
