Certified Registered Nurse Anesthetists (CRNAs) currently practice in all settings where anesthesia is delivered. Establishing intravenous (IV) access is one of the first steps to providing a safe and effective anesthetic, thus the ability to do this quickly and efficiently is a crucial skill for CRNAs. IV access can be difficult to obtain, especially in patients with unpalpable vasculature or a history of difficult venous access. One alternative to standard IV insertion methods is the utilization of ultrasonography for peripheral IV placement. Currently, many healthcare institutions lack structured ultrasound (U/S) training programs for CRNAs. A multi-modal education program for the use of U/S for peripheral IV placement was designed and implemented at the Fall 2021 Michigan Association of Nurse Anesthetists (MANA) conference. The course included a didactic education component, as well as a hands-on component using task trainers. Twenty-one CRNAs participated, with each one completing both a pre-education and post-education knowledge assessment, in addition to a hands-on skill check-off to demonstrate competency. Scores improved by an average of 1.61 (SD = 1.16) after education thus demonstrating a significant improvement, t(20) = 6.39, p < .001. Additionally, 100% of CRNAs were able to demonstrate competence in peripheral IV placement with ultrasound on a task trainer following education and practice. Therefore, multi-modal education in the use of ultrasound for peripheral IV placement is effective in increasing CRNAs’ knowledge and competence in this skill.
