可视化超声技术在重症病人疑难血管穿刺中的应用

目的探讨可视化超声技术在重症病人疑难血管穿刺中的应用。方法收集ICU外周疑难血管穿刺病人120例，随机分为2组，60例病人按照传统穿刺法为对照组，60例病人按照可视化多普勒超声引导法穿刺作为观察组，观察对比2组的穿刺时间、一次性成功率、并发症发生率。结果与对照组比较，观察组的一次性穿刺成功率和总成功率较高，皮下血肿、局部感染、神经损伤等并发症发生率较低，观察组穿刺成功所用时间较少（P < 0.01）。结论将可视化超声技术应用在重症病人疑难血管穿刺中，能够显著提高一次性和总体穿刺成功率、缩短穿刺时间，且并发症少。

Application value of the visualized ultrasound technology in difficult vascular puncture of severe patients

ObjectiveTo explore the application value of visualized ultrasound technology in difficult vascular puncture of severe patients.MethodsOne hundred and twenty patients with difficult vascular puncture in ICU were randomly divided into the control group and observation group(60 cases in each group).The control group was treated with traditional puncture method, and the observation group was treated with Doppler ultrasound guiding peripheral vein puncture method.The puncture time, one-time success rate and incidence rate of complication were observed and compared between two groups.ResultsCompared with the control group, the one-time success rate and total success rate of puncture in observation group were higher, the incidence rates of complications such as subcutaneous hematoma, local infection and nerve injury were lower, and the time of successful puncture was less in observation group(P < 0.01).ConclusionsThe application of visualized ultrasound technology in difficult vascular puncture of severe patients can significantly improve the success rate of puncture, shorten the time of puncture, reduce the pain of patients.
