摘　　要：目的 探讨注射器残留抗凝剂对患儿血气及电解质结果的影响。方法 对30例患儿同时用常规法和改良法采集血样本各30份,对所测得的血气和电解质结果进行比较分析。结果 改良法所测得的PCO2、K+、Ca2+、Hct值均高于常规法,而Na+值低于常规法,两者比较,差异有显著性意义(P<0.01,P<0.05)。结论 改良法可以减少血样被抗凝剂残留造成的结果误差。Objective To investigate the effects of the residual antico; gulant in syringe on the results of blood gas analysis and electrolytes in diseased children. Methods Thirty blood samples by routine method and 30 blood samples by modified method from 30 diseased children were collected respectively. The measured results of blood gas analysis and electrolytes were analyzed comparatively. Results The values of PCO2, K+ , Ca2+ and Hct measured by modified method were all higher than by routine method (P<0. 01), but th: value of Na+ measured by modified method was lower than by routine method (P<0. 05). Conclusion The modified method could decease the error caused by residual anticoagulant.
