目的探讨一种既不浪费血液,又能准确检测血气分析、活化部分凝血活酶时间(APTT)的从肝素维持的动脉置管中采血的方法.方法对30例动脉测压的患儿,用常规法(弃含有肝素的血液3～5ml)和改良法(不弃血)分别在同一时段从动脉置管处采血.用采集的血样检测血气分析和APTT,并比较两种方法采血所需的时间.结果两种采血方法检测的血气分析、APTT结果差异无统计学意义(P＞0.05).改良法操作时间明显短于常规法[(187.87±15.05)s比(275.73±14.75)s],差异有统计学意义(t=22.84,P＜0.01).结论不弃血采血法检测血气分析、APTT结果准确,可以替代常规采血法,做到了不弃血,不浪费血液,大大降低医源性失血,且节约了护士操作时间.

Objective To investigate the difference of blood sampling methods from heparin maintained arterial catheter for blood gas analysis and activated partial thromboplastin time (APTT).Methods Conventional and modified arterial catheter blood sampling methods were applied at the same period of time to 30 cases with arterial pressure measurement.3-5 ml blood containing heparin was disposed in conventional method.No blood was disposed for the modified method.The samples were used for blood gas analysis and APTT.The operation time of the sampling by two methods were compared.Results No significant difference was seen for the blood gas analysis and APTT from the blood samples collected by two different methods (P ＞ 0.05).The operation time of modified method was significantly shorter than that of the conventional method [(187.87 ±15.05)s vs (275.73 ±14.75)s,t =22.84;P＜0.01].Conclusions Arterial catheter blood sampling from heparin maintained blood by the modified method gives accurate clinical laboratory results,in this case,the blood gas analysis and the APTT.No blood is wasted and the operation time for the nurses is reduced.The modified method could be an alternative to the conventional blood collection method.
