The impact of two arterial catheters, different in diameter and length, on postcannulation radial artery diameter, blood flow, and occlusion in atherosclerotic patients

Abstract

A 22-gauge catheter for radial arterial cannulation in patients with atherosclerosis provides unchanged postcannulated radial artery diameter, decreases postcannulation complications, and improves the first-attempt success rate.

Evaluation of radial and ulnar blood flow after radial artery cannulation with 20‐ and 22‐gauge cannulae using duplex Doppler ultrasound

“…Thus, cannula size does not seem to affect the blood flow disturbance, when using 20‐G or 22‐G cannulae during general anaesthesia in a normal population. However, cannula size may be an important factor in radial artery flow disturbance after decannulation in atherosclerotic patients [6]. In a study performed in atherosclerotic patients, radial artery blood flow was significantly decreased 24 h after decannulation in patients who had undergone cannulation with a 20‐G cannula compared with those in whom a 22‐G cannula had been inserted [6].…”

These results might have been related to puncture injury to the radial artery in patients who have atherosclerotic vessels with abnormal wall structures.…”

“…Sample size calculations were based on arterial diameter changes reported in previous studies [6, 7]. The standard deviation of the radial artery diameter was 0.45 mm.…”

Late evaluation of upper limb arterial flow in patients after long radial (PiCCO™) catheter placement

“…Most existing studies on arterial patency following these interventions have been conducted to evaluate acute ischemic complications as well as complications of the technique (pseudo-aneurysm, bleeding, and arterial spasms) [ 7 ]. However, few studies [ 8 - 10 ] have looked at residual permeability and flow of superior limb arteries after recovery of the patient, and none has been conducted after the use of long radial artery catheters.…”

Impact of Diabetes Mellitus on Radial and Ulnar Arterial Vasoreactivity after Radial Artery Cannulation: A Randomized Controlled trial

“…In contrast to the immense amount of information available regarding radial artery vasoreactivity with respect to vascular surgery and coronary intervention, very few studies have explored changes in radial artery related to cannulation access for real-time blood pressure monitoring. 10 , 22 Similarly, although DM strongly influences vasoreactivity, 23 , 24 its specific impact on vasoreactivity after simple arterial cannulation for invasive blood pressure monitoring is not well-studied. The procedure is widely adopted, yet still carries a high risk of complications, especially in patients with atherosclerosis-related risk factors.…”
