【摘要】 目的观察围手术期库存红细胞悬液在不同温度复温后输注的临床效果。方法选择择期手术成年患者80例,均为在围手术期接受临床输注红细胞悬液,随机均分为4组,按复温水温起始温度不同分为1组(32℃)、2组(35℃)、3组(38℃)及对照组,每组20例,每例输注红细胞悬液2U。红细胞悬液由血库取出后,对照组红细胞悬液放置于室温中30min以上再进行输注,1~3组分别在起始温度为32、35、38℃水中复温15 min后再进行输注。观察输注前30min和输注后30min患者肛温变化、输注过程中血管痉挛性收缩发生率、麻醉苏醒期寒战发生率。结果对照组和1组患者输注后体温明显低于输注前体温(P<0.05),2组和3组输注前后体温变化无统计学意义(P>0.05),2组和3组患者输注后体温分别与对照组输注后比较差异有统计学意义(P<0.05)。2组和3组患者均未发生血管痉挛性收缩而影响输注速度,明显好于对照组和1组(P<0.05)。麻醉苏醒期寒战发生率,对照组>1组>2组>3组,4组之间比较差异有统计学意义(P<0.05)。结论库存红细胞悬液输注前采用35~38℃水温进行复温后输注的临床效果优于室温条件下和32℃水温复温者。更多还原

【Abstract】 Objective To observe the clinical effect of different preheating temperature of red blood cells in reserve before transfusion during the operation.Methods Eighty adult patients(ASAⅠ-Ⅱ)were divided randomly into four groups(group1,group 2,group 3and group C,n=20each).All patients were transfused intravenously with red blood cells in reserve during the operation.Red blood cells in reserve in Group 1-3were preheated in water with which temperature was 32,35,38 ℃respectively for 15 minutes before transfusion.Red blood cells in reserve in Group C were put in the operation room that room temperature was normal for 30 minutes.The anus temperature of patients was recorded at the time point of 30 minutes before and 30 minutes after the blood transfusion.The rates of vascular convulsion contract during the blood transfusion and the rates of shivering during the anesthesia recovery period after the operation were recorded.Results After the blood transfusion,the body temperature of the patients in group C was significantly lower than that before the blood transfusion(P<0.05),and significantly lower than that in group 2and in group 3(P<0.05).The rates of vascular convulsion contract during the blood transfusion in group C and group 1were significantly higher than that in group 2and group 3(P<0.05).The rates of shivering during the anesthesia recovery period after the operation in group C and group 1were significantly higher than that in group 2and group 3(P<0.05).Conclusion The clinical effects of red blood cell in reserve in 35-38 ℃preheating water is better than that in 32 ℃ and normal room temperature.更多还原
