中文摘要:
      目的 研究限制性输血策略指导输血对单病种二尖瓣置换术结果的影响。方法 在2011年6月至2016年6月的中国成人心脏外科数据库华西医院分库中,分别连续选取不同输血策略时期行单纯二尖瓣置换术患者各120例,分为开放性输血策略组和限制性输血策略组两组。入院时行血常规、肝肾功能、凝血功能、输血前全套、血型、心脏超声等检查并记录,同时记录围术期患者相关临床数据,比较不同输血策略指导下患者输血量、主要并发症及死亡率等。结果 不同输血策略对二尖瓣置换术患者术后输血量影响明显,红细胞由限制性输血策略前的(3.2±1.1) U降低至(1.8±1.5) U,差异有统计学意义(P=0.01),但血浆由限制性输血策略前的(325.7±96.5) mL上升至(385.2±86.2) mL,差异有统计学意义(P=0.04)。两组患者在主要并发症方面存在差异(39.2% vs. 31.7%,P=0.04),特别是与呼吸相关的并发症,如呼吸机使用>24 h的患者比例(P=0.03)、总呼吸机使用时间(P=0.03)、肺部感染率(P=0.04)等,限制性输血策略组患者明显优于开放性输血策略组。同时限制性输血策略组患者较开放性输血策略组患者ICU时间缩短(P=0.02)、住院总费用降低(P=0.02),但不同的输血策略并不影响患者围术期死亡率(P>0.05)。结论 限制性输血策略在降低单病种二尖瓣置换术患者主要并发症风险的同时降低医疗费用,但不能减少除红细胞外的其它血液制品用量,此策略需进一步完善。
英文摘要:
      Objective To investigate effects of restrictive transfusion on the outcome of mitral valve replacement. Methods We selected 120 continuous patients of mitral valve replacement from June 2011 to June 2016. Based on the different blood transfusion strategy, the patients were divided into two groups: liberal blood transfusion group and restrictive blood transfusion strategy group. The blood routine test, liver and kidney function, coagulation function, full examination before blood transfusion, blood types, echocardiography and so on were examined when the patients were admitted to hospital, also the clinical data of perioperative patients were recorded, and blood transfusion volume, major complication and mortality were compared between the two groups. Results The transfusion volume of red blood cells decreased from (3.2±1.1) to (1.8±1.5) U with restrictive transfusion, the difference was statistically significant (P=0.01), while plasma volume increased from (325.7±96.5) mL to (385.2±86.2) mL (P=0.04). There were differences in major complications between the two groups (39.2% vs. 31.7%, P=0.04), especially for respiratory-related complications such as the proportion of using ventilator >24 h (P=0.03), total time using ventilator (P=0.03), lung infection rate (P=0.04). The restrictive transfusion group had better outcome with less cost of hospitalization. The mortality was not different (P>0.05). Conclusion Restrictive transfusion strategy reduces the incidence of major complications in patients of mitral valve replacement with less cost.
