Abstract:

Objective To explore the application value of ultrasound-guided improved puncture in open venous indwelling needle catheterization for patients undergoing surgery. Method A total of 253 patients who were admitted to Suizhou Zengdu Hospital from October 2020 to June 2021 and needed peripheral venous indwelling needle were randomly divided into two groups: A (128 cases) and B (125 cases), in which group A underwent improved ultrasound-guided puncture and group B underwent conventional puncture. The success rate of onetime puncture and catheterization was compared between the two groups. The number of puncture times, operation time and pain degree during puncture were compared between the two groups. The incidence of complications was compared between the two groups. Result The success rate of one-time puncture catheterization in group A was 82.81%, which was significantly higher than that in group B (P ＜ 0.05). Operation time and numerical rating scale score in group A were significantly lower than those in group B (all P ＜ 0.05). The total incidence of puncture

complications in group A was significantly lower than that in group B (P ＜ 0.05). Conclusion The improved puncture guided by ultrasound can significantly improve the puncture efficiency, reduce the pain and effectively prevent the puncture complications in the operation of open venous indwelling needle.
