血液保护在心脏手术中的应用

目的探讨血液保护在心外科围手术中的作用。方法回顾性分析60例接受心脏手术患者的临床资料，将其中采用常规血液保护进行手术的30例患者定义为对照组，将采用改进血液保护进行手术的30例患者定义为观察组，对两组患者手术后的血红细胞比容情况、输血情况及胸腔引流量等资料进行比较分析。结果观察组的人均输血量（0．89±1．12）U及人均胸腔引流量（303±85）mL均明显少于对照组的人均输血量（1．07±1．68）U及人均胸腔引流量（571±163）mL，差异有统计学意义（P〈0．05）；术后红细胞比容情况明显优于对照组，差异亦有统计学意义（P〈0．05）。结论在心外科围手术期中使用改进血液保护，可减少患者的围手术期输血量，降低术后胸腔引流量，提高红细胞比容，有利于促进患者术后康复。

Application of Blood Conservation in Cardiac Surgery

Objective To study the role of blood conservation in cardiac surgery perioperative. Methods The clinical data of 60 patients undergoing cardiac surgery were analyzed retrospectively, in which 30 patients with surgery under conventional blood conservation were selected as the control group, and 30 patients with surgery under improved blood conservation were selected as the observation group. The blood hematocrit, blood transfusion and chest drainage volume after operation were compared between two groups. Results The mean capita amount of blood transfusion（0.89 ± 1.12）U and mean capita chest drainage volume （303 ±85）mL of the observation group was less than（1.07 ± 1.68）U and（571 ± 163）mL of the control group, and the difference was statistically significant （P〈0.05）. The blood hematocrit after operation of observation group was better than that of control group, and the difference was statistically significant （P 〈0.05）. Conclusions The application of improved blood conservation during perioperative period of cardiac surgery can reduce the blood transfusion amount and chest drainage volume, improve blood hematocrit, so as to promote patients＇ rehabilitation after surgery.
