目的回顾性观察BD动脉采血器在急诊危重症患者动脉采血中的应用效果。方法连续收集100例需要进行血气分析的急诊危重症患者应用BD动脉采血器进行采血，并总结100例采用一次性注射器采集动脉血的急诊危重症患者作为对照组，将两组标本合格率、一次性穿刺成功率、误抽静脉血率、混入气泡率、穿刺局部皮下血肿和瘀斑率、患者主观疼痛程度进行和穿刺后压迫止血时间比较。结果观察组各项指标均优于对照组，差异存在统计学意义（<0.01）。结论在急诊危重症抢救过程中，积极采用BD动脉采血器采血能有效提高一次性穿刺成功率、提高动脉血气标本的合格率并有效减轻患者的疼痛程度、减少局部皮下血肿与瘀斑发生，在急诊抢救工作中值得推广应用。“,”Objective To retrospective study,we compare the clinical ef ects of arterial blood drawing with BD Critical Care Col ection Syringes and Common Disposable Syringes.Methods To compare BD Critical Care Col ection Syringes for 100 patients,and randomly selected 100 patients who used Common Disposable Syringes for arterial blood drawing.We compared those items:Specimen qualified rate,success rate of puncture by once,happen rate of vein blood drawing,happen rate of mixed air,happen rate of haematoma and extravasated blood in puncture site and pain level and the wounds pressing time after blood sampling.Results Index of BD Critical Care Col ection Syringes is:Specimen qualified rate 89%,success rate of puncture by once 96%,happen rate of vein blood drawing 5%, happen rate of mixed air 2%,happen rate of haematoma and extravasated blood in puncture site 15%and pain level 5%.According to the control group,Specimen qualified rate 85%,success rate of puncture by once 82%,happen rate of vein blood drawing 14%,happen rate of mixed air 8%,happen rate of haematoma and extravasated blood in puncture site 20%and pain level 20%.BD Critical Care Col ection Syringes were obviously lower than Common Disposable Syringes in happen rate of vein blood drawing,happen rate of mixed air,happen rate of haematoma and extravasated blood in puncture site and pain level,and obviously higher in Specimen qualified rate, success rate of puncture by once and the wounds pressing time after blood simpling ( <0.01).Conclusion BD Critical Care Col ection Syringes are simple in operation, and have lit le bad response,lit le pain to patiens,this should be used in clinical practice normaly.
