Abstract:
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.
