目的 研究接受心脏外科手术患者术前血红蛋白浓度和术后使用临床医疗资源之间的关系.方法 接受心脏外科手术患者108例,采用回顾性、观察队列研究分析术前血红蛋白浓度和术后输注血制品、因出血或心包填塞二次开胸率、围手术期死亡率、ICU时间和总住院时间之间的关系.结果 术前血红蛋白每升高10g/L,术后输注红细胞的相对风险下降8.0%,输注血小板的相对风险下降3.0%,输注新鲜冰冻血浆的相对风险下降6.0%.术前血红蛋白每下降10g/L,ICU时间增加7.0%、总住院时间增加16.0%.术前血红蛋白浓度与二次开胸率的相对风险以及围手术期死亡率无明显关系.结论 心脏外科手术的患者,术前血红蛋白浓度与术后医疗资源的增加密切相关,纠正术前低血红蛋白浓度有利于节约术后医疗资源.“,”Objective To explore the relationship of preoperative hemoglobin concentration and use of hospital resources.Methods 108 patients receiving cardiac surgery in the central hospital of wuhan were included.The relationship of preoperative hemoglobin concentration was explored on blood transfusion rates,return to the operating room for bleeding and/or cardiac tamponade,postoperative intensive care unit(ICU)and in-hospital length of stay,and mortality.Results For every 10-unit increase in hemoglobin(g/L),blood transfusion requirements were reduced by 8.0%,6.0%,and 3.0% for red blood cell units,platelet pools,and fresh frozen plasma units,respectively.For each 10-unit decrease in hemoglobin(g/L),the probability(over time)of discharge from the ICU and hospital increased 7.0%,16.0% respectively.Conclusion A lower preoperative hemoglobin concentration resulted in increased use of hospital resources after cardiac surgery.Therefore,the correction of decreasing preoperative hemoglobin concentration could improve the use of hospital resources after cardiac surgery.
