Use of a wire-guided cannula for radial arterial cannulation

Abstract

We compared the success rates of arterial cannulation with a wire-guided cannula (WGC) and the direct technique with a conventional non-wire-guided cannula (non-WGC). A total of 100 adult patients requiring an arterial line in the operating room were assigned randomly to undergo radial arterial cannulation either with the WGC or with the non-WGC. No significant difference in success rates and insertion times could be demonstrated between the WGC and the non-WGC (78.4% vs 67.3% and 22.6 +/- 13.2 s vs 23.0 +/- 19.3 s, respectively). Among the less experienced operators, insertion time was shorter with the WGC than with the non-WGC (27.7 +/- 11.9 s vs 39.8 +/- 20.4 s; P < 0.05), although the success rate was similar for the two types of cannula. Patient characteristics did not affect either the success rates or the insertion times for the two types of cannula. In conclusion, we have confirmed that the success rates of radial arterial cannulation for patients whose physical status is relatively good were similar with the use of the WGC and the non-WGC.

Optimal site for ultrasound-guided venous catheterisation in paediatric patients: an observational study to investigate predictors for catheterisation success and a randomised controlled study to determine the most successful site

“…The through-and-through technique was used only as a backup approach because it often produces a hematoma beyond the vein’s posterior wall, which can compromise subsequent catheterisation attempts should one prove necessary. The benefits [ 32 - 34 ] and difficulties [ 35 ] of other techniques to facilitate vessel catheterisation, including using guide-wires and the bevel-down approach, are well verified in adults but remain poorly evaluated in paediatric patients [ 33 ]. Ultrasound-guided peripheral venous catheterisation may be more successful when combined with these ancillary techniques.…”

Topical nitroglycerin and lidocaine locally vasodilate the radial artery without affecting systemic blood pressure: A dose-finding phase I study

“…Techniques for improving radial artery cannulation have included performing the modified Allen test and/or Barbeau test to assess for patency of the vessel [5], direct visualization of the vessel with ultrasonography at the time of cannulation, and use of a wireguided cannula [6][7][8].…”

Ultrasound evidence of the optimal wrist position for radial artery cannulation

“…3,12 This result is likely due to the smaller size of the female radial artery. Our study focused on the relationship between the diameter of the radial artery and the angle of the wrist joint, and showed that excessive extension of the wrist joint angle reduces arterial size.…”
