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.
