The application of ultrasound-guided arterial catheterization in internships of anesthesiology

Abstract

Objective To evaluate the effect of ultrasound-guided arterial catheterization in intern-ships of anesthesiology. Methods Sixty students were randomly divided into ultrasound-guided teaching group(n=30, 3 male)and traditional teaching group(n=30, 4 male). In the two groups, the ultrasound-guided arterial catheterization technology and artery catheterization technique were adopted respectively for teaching. The success rate of arterial catheterization was compared between the two groups after 2 months intern-ships and when finishing internships of anesthesiology. The questionnaire was investigated in ultrasound-guided teaching group after finished internships of anesthesiology. Results The success rate of arterial catheterization in ultrasound-guided teaching group was extremely higher than in traditional teaching group after 2 months internships of anesthesiology(52±8)% vs.(38±10)%,(χ2=7.746 , P=0.005). After finishing internships of anesthesiology, the success rate of arterial catheterization was(67 ± 7)% in ultrasound-guided teaching group and(59±9)% in traditional teaching group(χ2=5.531 , P=0.036). And all students thought ultrasound-guided arterial catheters teaching was helpful to them and could improve their learning interest. Conclusion Ultrasound-guided arterial catheterization is beneficial to the internship teaching of under-graduate of anesthesiology, which can help them to master the arterial catheterization technique better, and improve the success rate of arterial catheterization and their learning interest.
