海南地区悬浮红细胞实际容量调查

目的：调查海南地区悬浮红细胞实际容量情况。方法随机抽样1U悬浮红细胞100袋，2 U悬浮红细胞100袋及临床输血后回收血袋各10袋（含10 cm左右血辫子），采液控制器称量其容量（ml），计算得到实际血液容量，利用SAS软件进行统计学分析。结果1 U空血袋和2 U空血袋的容量分别为26.4 ml、33.2 ml；1U悬浮红细胞和2 U悬浮红细胞的实际容量分别为161.98 ml、327.92 ml，95%置信区间范围分别为（159.76，174.2）、（323.54，332.29），1 U悬浮红细胞容量极差62 ml，2 U悬浮红细胞极差82 ml。结论建议海南省地区有需要精确记录液体出入量的患者，对输血前悬浮红细胞容量进行精确称量。

Actual capacity of suspended red blood cells in Hainan Area

Objective To investigate the actual capacity of suspended red blood cells from Hainan Provincial Blood Center. Methods One hundred bags of 1U suspended red blood cells and 100 bags of 2U suspended red blood cells were collected in Hainan Provincial Blood Center. Ten hollow blood bags were collected after 1U or 2U red blood cells has been transfused respectively. The capacity was assessed by microcomputer liquid withdrawal weighing controller, and actual capacity of suspended red blood cells was calculated. Results The capacity of 1U and 2U hollow blood bags were 26.4 ml and 33.2 ml respectively. The actual capacity of 1U and 2U suspended red blood cells were 161.98 ml and 327.92 ml respectively, and the 95%confidences intervals were （159.76, 174.2）、（323.54, 332.29）,and capacity of ranges of 1U and 2U were 62 ml and 82 ml respectively. Conclusion In Hainan Province, the actual capacity of suspended red blood cells should be assessed exactly when the receptors need precise intake and output records.
