血液回收在成人心脏瓣膜置换术中的应用价值

The application of blood recovery in adult cardiac valve replacement surgery

目的探讨血液回收在成人心脏瓣膜置换术中的临床应用价值。方法选取2008年5月至2012年4月于该院行心脏瓣膜置换术的556例患者,根据其术中输血方式分为对照组(278例)和观察组(278例),观察组患者进行自体血液回收,对照组患者不进行自体血液回收,观察两组患者各临床指标,并进行统计学对比分析。结果两组患者术后24h血常规(血红蛋白、红细胞比容、血小板等)及血气分析(酸碱度、钾离子、乳酸等)结果比较,差异无统计学意义(P>0.05);术后观察组患者胸腔引流量与对照组患者比较差异无统计学意义(P>0.05);观察组患者库存血用量(263.83±19.23)mL明显少于对照组(615.24±20.34)mL,组间比较差异有统计学意义(P<0.05)。结论在成人心脏瓣膜置换术中,血液回收可有效补充血容量、减少自体血丢失,可明显减少患者库存血输入量,值得推广。

Objective To investigate the clinical value of blood recovery in the heart valve replacement surgery of adults. Methods Selected 556 patients accepted cardiac valve replacement surgery from May 2008 to April 2012 in our hospital,and divid- ed into control group（278 cases） and observation group（278 cases） according to the way of intraoperative blood transfusion patients in observation group underwent autologous blood recovery and patients in control group underwent without autologous blood recov- ery,the clinical parameters were observed and statistically analyzed. Results The differences of blood routine after 24 h（such as he- moglobin, hematocrit, platelets, etc. ） and blood gas analysis（such as pH, potassium ions, lactic acid, etc. ） between two groups were not significantly different,which is statistically insignificant（P〉0.05）;the postoperative chest drainage of patients in observation group was not significantly different from that of patients in control group, which was statistically insignificant（P〉0.05）;the a- mount of banked blood in observation group（263.83 ±19.23）mL was significantly lower than that in control group（615.24 ± 20.34）mL,the difference between two groups was statistically significant（P〈0.05）. Conclusion In heart valve replacement surgery of adults, blood recovery can effectively add blood volume, reduce autologous blood loss, and significantly reduce the amount of banked blood input, which is worthy of promotion.
