Application effect of an ultrasound probe fixation bracket assisted ultrasound-guided venipuncture in difficult intravenous access

目的观察辅助超声引导静脉穿刺的超声探头固定支架在困难静脉通路中应用的效果。方法采用方便抽样法选取2017年11月至2019年5月困难静脉通路的住院患者共105例。选取2017年11月至2018年5月39例患者作为对照组,采用超声引导下外周静脉留置针穿刺技术进行穿刺;选取2018年6月至2019年5月66例患者作为试验组,采用超声探头固定支架辅助超声引导外周静脉留置针穿刺技术进行穿刺。比较2组患者一针穿刺成功率、穿刺次数、疼痛程度。结果试验组一针穿刺成功率为92.4%(61/66),对照组一针穿刺成功率为66.7%(26/39),2组比较差异有统计学意义(χ^2值为11.450,P<0.01);试验组与对照组穿刺次数分别为(1.08±0.27)、(1.44±0.72)次,2组比较差异有统计学意义(Z值为-3.435,P<0.01);试验组与对照组疼痛评分分别为(2.00±0.95)、(3.08±1.37)分,2组比较差异有统计学意义(Z值为-4.159,P<0.01)。结论困难静脉通路患者应用超声探头固定支架辅助超声引导外周静脉穿刺技术提高了一针穿刺成功率,减少穿刺次数,减轻疼痛程度。

Objective To observe the effect of ultrasound probe fixation bracket assisted ultrasound-guided venipuncture in difficult intravenous access.Methods A total of 105 inpatients with difficult intravenous access from November 2017 to May 2019 were selected by convenient sampling method.From November 2017 to May 2018,39 patients as the control group were treated with ultrasound-guided peripheral venous indwelling needle puncture technique.From June 2018 to May 2019,66 patients as the experimental group were treated with ultrasound probe fixation bracket assisted ultrasound-guided peripheral vein indwelling needle puncture technique.The success rate of one needle puncture,the times of puncture and the degree of pain were compared between the two groups.Results The success rate of one needle puncture was 92.4%(61/66)in the experimental group and 66.7%(26/39)in the control group(χ^2 value was 11.450,P<0.01);The puncture times in the experimental group and the control group were 1.08±0.27 and 1.44±0.72,and the difference was statistically significant(Z value was-3.435,P<0.01).The pain scores of the experimental group and the control group were 2.00±0.95 and 3.08±1.37,and the difference was statistically significant(Z value was-4.159,P<0.01).Conclusions The application of ultrasound probe fixation bracket assisted ultrasound-guided peripheral venipuncture technique in patients with difficult intravenous access can improve the success rate of one needle puncture,reduce the number of puncture and reduce the degree of pain.
