Abstract

BACKGROUND: The optimal method for teaching ultrasound guided peripheral IV (USGPIV) insertion is unknown. Poor needle tip visualization has been cited for USGPIV failure. Twinkle artifact (TA), visualized with color Doppler, is used in other clinical settings. Our objective was to investigate whether teaching students USGPIV placement utilizing TA would enhance needle tip visualization and improve first pass success.

METHODS: This was a prospective, randomized study of premedical and preclinical medical students without prior USGPIV experience. Students were given a standardized didactic session on USGPIV placement before being randomized and separated to learn and practice USGPIV with or without TA (control). The students were given 5 min to perform USGPIV on phantom models. The primary outcome was the rate of first pass success. Secondary outcomes included total time to cannulation, rate of posterior venous wall puncture, and total number of attempts.

RESULTS: Rates of first pass success were similar in both the TA (82%) and control groups (57%),

CONCLUSION: In this study of utilizing TA to aid in USGPIV placement, students were able to achieve successful cannulation in a shorter amount of time. There was no significant difference in first pass success. Future studies should utilize a larger sample size and evaluate the utility of TA when placing USGPIV on patients.
