Application of radial arterial puncture cannulation under ultrasonic guidance in patients with critical diseases

Abstract

To explore the clinicaleffect of radial arterial puncture cannulationunder ultrasonic guidance in patients with critical diseases. Methods: From December 2016 to May 2017, 120 patients under critical conditions in Department ofIntensive Care Unit, Xiangya Hospital, Central South University, who received arterial cannulation, were randomly divided into 2 groups: a control group (traditional blind puncture method) and an observation group (ultrasound-guided radial arterial cannulation) (60 cases in each group). The success ratio of radial arterial puncture cannulation by one time, total success ratio of radial arterial puncture cannulation, numbers of puncture, the rate of complications and the time of consumption were compared between the 2 groups. Results: There was no statistically significant difference in the total success ratio of radial arterial puncture cannulationin the 2 groups (P>0.05). The success ratio radial arterial puncture cannulation by one time was significantly greater in the observation group than that in the control group (P<0.05); the numbers of puncture, the rate of complications and the time of consumption in the observation group were lower than those in the control group, with statistically significant (all P<0.05). Conclusion: The application of ultrasound-guided radial arterial puncturecannulation can improve the success ratio of radial arterial puncturecannulation by one time, decrease the numbers of puncture, reduce the incidence of complications and save operation time.
