超声引导下静脉血液标本采集流程在急诊创伤性休克患者中的应用研究

The application of ultrasound guided venous blood specimen collection process in emergency traumatic shockpatients

目的探讨超声引导下静脉血液标本采集流程在急诊创伤性休克患者中的应用效果。方法选取2020年9月—2021年12月杭州市某三级甲等医院急诊抢救室的创伤性休克患者为研究对象,将流程应用后(2021年5月—12月)的患者纳入试验组,流程应用前(2020年9月—2021年4月)的患者纳入对照组。试验组共56例以超声引导下静脉血液标本采集流程进行静脉采血,对照组共52例以超声引导下静脉血液标本无采集流程进行静脉采血,比较两组静脉血液标本采集首次穿刺成功率、穿刺用时、血常规及ABO血型标本送出时间、急诊室滞留时间、并发症发生率、标本溶血率及患者舒适度的差异。结果﹑试验组较对照组穿刺用时、血常规及ABO血型标本送出时间均明显降低,急诊室滞留时间明显缩短,且首次穿刺成功率明显提高,差异均具有统计学意义(P<0.05);试验组皮下血肿发生率及标本溶血率明显低于对照组,差异具有统计学意义(P<0.05);试验组患者舒适状况量表总分高于对照组,差异具有统计学意义(P<0.05)。结论应用超声引导下静脉血液标本采集流程,可有效指导急诊创伤性休克患者的临床采血,降低并发症及溶血率的发生率,增加患者的舒适度。

Objective To explore the application effect of ultrasound-guided venous blood sample collection process in emergency patients with traumatic shock.Methods From September 2020 to December 2021,patients with emergency traumatic shock in the emergency room of a tertiary Grade A hospital in Hangzhou were selected as the research objects.Patients after the application of the process(from May to December 2021)were included in the experimental group,and patients before the application of the process(from September 2020 to April 2021)were included in the control group.A total of 56 cases in the experimental group received venous blood collection process guided by ultrasound,while 52 cases in the control group received venous blood collection guided by ultrasound without collection process.The success rate of first puncture,puncture time,blood routine and ABO blood group delivery time,emergency room retention time,complication rate,sample hemolysis rate and patient comfort were compared between the two groups.Results Compared with the control group,the puncture time,blood routine and ABO blood group delivery time of the experimental group were significantly reduced,the retention time of emergency room was significantly shortened,and the success rate of the first puncture was significantly increased(P<0.05).The complication rate and hemolysis rate of subcutaneous hematoma in the experimental group were significantly lower than those in the control group(P<0.05).The total score of the comfort scale in the experimental group was higher than that in the control group,and the difference was statistically significant(P<0.05).Conclusions The application of ultrasound-guided venous blood sample collection process can effectively guide the clinical blood collection of emergency traumatic shock patients,reduce the incidence of complications and hemolysis rate,and increase the comfort of patients.
