改良指尖定位引导血管穿刺法在桡动脉采血中的应用

Application of improved fingertip localization guided vascular puncture in radial artery blood sampling

目的探讨改良指尖定位引导血管穿刺法在桡动脉采血中的应用效果。方法采用便利抽样法,选取2020年8—11月南京医科大学第一附属医院呼吸与危重症医学科采取桡动脉采血行血气分析的患者为研究对象。以8—9月采血的44例患者作为对照组,10—11月采血的44例患者作为试验组。对照组采用常规动脉穿刺法进行桡动脉采血;试验组采用改良指尖定位引导血管穿刺法进行桡动脉采血。比较两组患者桡动脉采血首次穿刺成功率、穿刺时长、穿刺时疼痛评分和穿刺后即时并发症发生率等。采用t检验和χ^(2)检验进行统计分析。结果两组患者桡动脉首次穿刺成功率试验组(81.82%)高于对照组(56.82%),试验组穿刺时长(34.600±2.442)s,低于对照组的(39.156±2.785)s,试验组疼痛评分(3.750±0.315)分,低于对照组的(4.318±0.306)分,差异均有统计学意义(P<0.05)。试验组未发生穿刺后即时并发症,对照组发生2例,两组差异无统计学意义(P>0.05)。结论改良指尖定位引导血管穿刺法能够提高桡动脉首次穿刺成功率,缩短穿刺时间,减轻患者疼痛。

Objective To explore the application effect of improved fingertip localization guided vascular puncture method in radial artery blood sampling.Methods Using the convenience sampling method,patients receiving radial artery blood sampling for blood gas analysis in Department of Respiratory and Critical Care Medicine of First Affiliated Hospital of Nanjing Medical University from August to November 2020 were selected as research objects.The 44 patients whose blood was collected from August to September were used as the control group,and 44 patients whose blood was collected from October to November were used as the experimental group.The control group used conventional arterial puncture to collect blood from the radial artery,while the experimental group used modified fingertip localization guided vascular puncture to collect blood from the radial artery.The success rate of first puncture,duration of puncture,pain score during puncture and incidence of immediate complications after puncture were compared between the two groups.The t test andχ^(2) test were used for statistical analysis.Results The first success rate of radial artery puncture of patients in the experimental group(81.82%)was higher than that in the control group(56.82%).The puncture time in the experimental group was(34.600±2.442)s,which was lower than(39.156±2.785)s in the control group.The pain score of the experimental group was(3.750±0.315),which was lower than(4.318±0.306)of the control group.All the differences were statistically significant(P<0.05).There were no immediate complications after puncture in the experimental group and 2 cases in the control group.There was no statistically significant difference between the two groups(P>0.05).Conclusions The improved fingertip localization guided vascular puncture method can increase the success rate of the first radial artery puncture,shorten the puncture time and reduce the pain of patients.
