摘要
目的 探讨输液泵控制外周动静脉同步换血的可行性及疗效。 方法 外周静脉输血 ,速度 15 0ml/h ,外周动脉抽血 ,采用留置针头 ,抽血速度与输血速度一致。多功能监护仪监测生活体征 ,记录有关参数。换血前后行血常规、生化、肝功能、血培养等检查。 结果 2 1例患儿平均总胆红素由换血前 43 4 44 μmol/L下降至换血后 2 60 3 8μmol/L。换出率是 3 8 5 1% ,95 %的可信区间是 3 3 49%～ 43 5 3 %。平均换血量 163ml/kg。换血后除白细胞、血小板、Na+ 、BUN有轻微变化外 ,无明显并发症发生。 结论 输液泵控制下外周动静脉同步换血是简单、实用、安全的方法 。
Objective To investigate the practicable and effectiveness of pump-controlled exchange transfusion via peripheral vessels. Methods One catheter was inserted into a vein for donor blood transfusion at a rate of 150ml/hour. The another catheter connected three way stopcock was inserted into a artery for withdrawing blood at the same rate of infusion. Vital signs were monitored electronically and recorded.RBC,WBC,PLT,Bilirubin,K +,Na + and BUN were measured before and after exchange transfusion. Results Exchange transfusion was done on 21 cases. The mean Serum bilirubin concentration decreased from 434.44μmol/L to 260.38μmol/L after this procedure. The mean drop in serum bilirubin concentration was 38.51%,95%confidence interval of difference was 33.4%～43.53%.RBC,HB and Na + raised and WBC,PLT,BUN descended slightly after exchange transfusion. Conclusion Peripheral vessel exchange transfusion controlled by infusion pumb is simple,practicable and safe with few complications.
