Summary

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.

Detailed description

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

Interventions

Type	Name	Description
OTHER	Dynamic Needle Tip Positioning Technique in Short Axis Approach (DNTP - SA)	Ultrasound guided radial artery cannulation by Dynamic Needle Tip Positioning Technique in Short Axis Approach (DNTP - SA) will be performed by an experienced anesthesiologist who has no subsequent role in the study. The ultrasound transducer is oriented transversely to the radial artery at the wrist, and the vessel appears as a circular anechoic structure in the ultrasound screen 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.
OTHER	Long Axis Approach (LA)	Ultrasound guided radial artery cannulation in Long Axis Approach (LA) will be performed by an experienced anesthesiologist who has no subsequent role in the study. In the LA-IP approach, an ultrasound probe is placed parallel to the radial artery and the artery appears as a tubular anechoic structure in ultrasound.
