Progress in ultrasound-guided peripheral venous catheters puncture techniques

The use of ultrasound-guided peripheral venous catheterization technique in patients with difficult peripheral venous access has gradually become a basic skill for all professional healthcare providers.compared to the traditional blind puncture method, ultrasound guidance significantly increases the success rate of peripheral venous catheterization due to its dynamic and real-time visualization of blood vessels, reduces related complications, and enhances patient satisfaction. There are various methods of ultrasound guidance, and to master and effectively perform this technique, a comprehensive understanding of it is required. The purpose of this review is to provide concise and practical information to help clinical healthcare providers understand this technique, with a focus on introducing best practices and methods for its application, thereby offering references for its clinical promotion and application.
