Arterial Cannulation Clinical Trial
Official title:
Does the Dynamic Needle Tip Positioning Modification Technique in Short Axis Approach (DNTP - SA) Provides a Faster Ultrasound-guided Arterial Cannulation Than Long Axis (LA) Approach: A Prospective Randomized Controlled Study
The aim of the present study is to compare between Dynamic Needle Tip Positioning Modification Technique in Short Axis Approach (DNTP - SA) and Long Axis (LA) Approach for Ultrasound-guided Arterial Cannulation as regard time to successful arterial cannula insertion as well as the success rate in the first trial of insertion, number of attempts till successful arterial line placemen, complications, and operators' satisfaction.
Intraoperative Arterial cannulation is recently frequently required especially in high-risk patients or patients with expected major fluid shift. The most common site for arterial cannulation is the radial artery because of ease of accessibility, dual blood supply to the hand via the ulnar artery, and a low rate of complications. Complications from arterial cannulation include thrombosis, hematoma formation, edema and vasospasm. Two approaches are basically identified for ultrasound-guided radial artery cannulation, i.e., short-axis out-of-plane (SA-OOP) and long-axis in-plane (LA-IP) techniques. The dynamic needle tip positioning (DNTP) technique uses the short-axis view of the radial artery with gradual advancing of the needle till reaching the radial artery. Meanwhile, the ultrasound probe is being moved proximally in advance of the needle tip until it disappears from the ultrasound image. The cannula then advanced in the direction of the artery ;
