心脏瓣膜患者术后临床结局与血浆白蛋白关系的研究

目的:探讨心脏瓣膜患者术前、术后低蛋白血症对临床结局的影响。方法:2010年10月至2011年1月在我院心外科住院手术的心脏瓣膜病变患者154例,全部检查入院白蛋白(ALB)、术后每w查ALB,以出院前最后一次ALB作为术后ALB指标。ALB≥35 g/L为正常白蛋白组,<35 g/L为低白蛋白组。临床结局项目包括:术后住院时间,监护室停留时间,是否发生感染,是否二次手术,转归是否不良及住院费用。结果:术前ALB≥35 g/L组与<35 g/L组比较,在临床结局上差异无统计学意义(P>0.05);术后ALB水平与临床结局关系十分密切,ALB<35 g/L的患者术后住院时间和监护室停留时间比≥35 g/L患者明显延长(P<0.01),不良转归的发生率和感染的发生率明显高于ALB≥35 g/L的患者,二次手术及住院费用方面差异无统计学意义(P>0.05)。去除术前低蛋白血症的病例,这种趋向仍很明显。相关分析显示:术前ALB水平与患者术后住院时间呈负相关(r=-0.124,P=0.038);术后ALB水平与术后住院时间、监护室停留时间呈负相关(r=-0.544,P=0.0001和r=-0.198,P=0.001)。结论:在关注心瓣膜患者术前营养状态的同时,要特别关注心瓣膜病患者术后的营养状态,术后出现低ALB是影响心脏瓣膜手术病患者临床结局的重要因素之一。

Relationship between serum albumin level and clinical outcome in patient with heart valve operation

Objective:To study the effect of lower serum albumin level(before and after operation) to clinical outcome in the patient with heart valve surgery.Methods: A cross sectional study was carried out in 154 patients being hospitalized with heart valve operation between October 2010 and January 2011.The serum albumin(ALB) was examined at admission and once a week after operation.The last ALB before patient leaving hospital was defined as after operation ALB level.The clinical outcome was compared between lower A...
