摘　　要：目的调查急诊绿色通道对缩短血气分析标本周转时间(TAT)的作用,分析影响TAT的因素。方法回顾性分析浙江大学医学院附属第二医院2014年10月1日至2015年9月30日所有血气分析标本的TAT,比较分析绿色通道标本和其他来源标本的实验室前TAT及实验室内TAT。结果绿色通道、门诊急诊和住院急诊标本实验室前TAT均值分别为8.64、38.81和59.24min,实验室内TAT均值分别为6.20、6.60min和15.60min,绿色通道标本实验室前和实验室内TAT均值都明显小于门诊急诊和住院急诊标本;在标本接收高峰期,绿色通道标本相对于门诊急诊和住院急诊标本,实验室内TAT缩短的值和百分比明显高于其他时间段。结论绿色通道可缩短血气分析标本的TAT,尤其在标本接收高峰期,绿色通道对提高标本周转效率的作用尤为明显。Objective To investigate the effect of emergency green channel on reducing turn-around time（TAT）of specimens by blood gas analysis,and to analyze the influencing factors of TAT.Methods TAT of all specimens by blood gas analysis from October 1,2014 to September 30,2015 were statistically analyzed.Pre-analytical TAT and analytical TAT of specimens which came from green channel and other ways were compared.Results The mean pre-analytical TAT of green channel,outpatient and inpatient specimens were 8.64 min,38.81 min and 59.24 min,respectively.And the mean values of analytical TAT of green channel,outpatient and inpatient specimens were 6.20 min,6.60 min and 15.60 min,respectively.The mean values of pre-analytical TAT and analytical TAT of green channel specimens were significantly lower than that of the outpatient and inpatient specimens（P0.05）.At the peak period of the specimens receiving,the reduced time and percentage of analytical TAT of the green channel specimens were significantly higher than that in other periods of the groups of outpatient and inpatient specimens.Conclusion The implementation of the green channel system can reduce the TAT of specimens by blood gas analysis.In addition,the green channel system is more effective in improving the turn-around efficiency at the peak period of the specimen receiving than other periods.
