Comparison of procedural time with two different ultrasound-guided approaches for dorsalis pedis artery cannulation in adult patients: A randomized trial

Abstract

Background: In adult patients, there has never been an evaluation of short-axis out-of-plane versus long-axis in-plane approaches of ultrasound-guided dorsalis pedis artery cannulation. This research was conducted to compare these two techniques to cannulate the dorsal pedis artery. Methods: In this trial, 128 adult patients undergoing surgery and necessitating arterial cannulation were examined. Dorsalis pedis artery cannulation was performed utilizing an ultrasound by long-axis in-plane approach (group L) or short-axis out-of-plane (group S) techniques. Results: Group S had a higher first attempt success rate than group L (46.9% vs 28.6%, p = 0.039). The S group had a lower assessment time than the L group (11.48 ± 3.07 vs 19.68 ± 2.79 s; p = 0.000). Cannulation time was higher in the S group (18.91 ± 1.92 s) compared to the L group (12.48 ± 1.61 s; p = 0.000). Nevertheless, the total procedure time was comparable between the L group and the S group (32.16 ± 2.95 vs 30.42 ± 4.07 s; p = 0.107). Conclusions: In adults, both views of ultrasonography can be used to guide DPA cannulation. The cannulation time for the DPA in L group was less than the S group, whereas the assessment time was less in S group. The total procedure time, however, was similar between both the groups.
