【摘要】 目的:对一种国产红细胞洗涤机的性能进行评价研究。方法:随机抽取60袋悬浮红细胞,分为两组,实验组采用国产智能红细胞洗涤机及配套耗材制备洗涤红细胞,对照组用手工法制备,按照新版国家标准分别对实验组和对照组的血红蛋白含量、上清蛋白质含量、单位耗费时间和储存期末红细胞溶血率以及无菌实验相关指标进行检测分析。并观测相应制备产品在不同储存期各项质量指标的变化情况。结果:实验组红细胞洗涤机制备的洗涤红细胞的血红蛋白含量、上清蛋白质含量、单位耗费时间和储存期末红细胞溶血率分别是(49.13±4.64)g/bag、(0.39±1.10)g/bag、(32.97±6.23)min/bag和(0.31±0.09)%。对照组手工制备的洗涤红细胞的血红蛋白含量、上清蛋白质含量、单位耗费时间和储存期末红细胞溶血率分别是(43.05±4.87)g/bag、(0.38±1.24)g/bag、(54.50±6.85)min/bag和(0.53±0.12)%。血红蛋白含量、单位耗费时间和储存期末红细胞溶血率两组比较具有统计学差异(P<0.05)。结论:机器产品质量指标更优于手工方法,国产智能红细胞洗涤机更安全、高效。更多还原

【Abstract】 Objective:To use the national standard to compare the quality of washed red blood cells(washed RBCs)prepared by red blood cell washing machine and handmade.Methods:60 bags of RBCs were randomly divided into 2groups(n =30) that were experience group and control group respectively.Washed RBCs were prepared by red blood cell washing machine and handmade on experience group and control group respectively.The level of hemoglobin(Hb),supernatant protein,unit time and the rate of hemolysis were measured by the 2012 national standard.Results:The level of Hb,supernatant protein,unit time and the rate of hemolysis in experience group were(49.13 ±4.64) g/bag,(0.39 ± 1.10)g/bag,(32.97 ±6.23)min/bag and(0.31 ±0.09)%respectively.The level of Hb,supernatant protein,unit time and the rate of hemolysis in control group were(43.05 ±4.87) g/bag,(0.38 ± 1.24) g/bag,(54.50 ± 6.85) min/bag and(0.53 ±0.12)%.The differences in Hb,unit time and the rate of hemolysis were statistically significant between these 2groups(P<0.05).Conclusion:All of the preparing products can meet the requirements of the new national standard in two groups.The quality of washed RBCs prepared by red blood cell washing machine was better than by handmade.The method of red blood cell washing machine was safter and shorter time.更多还原
