An In Vitro Assessment of the Efficacy of Various IV Cannulas for the Rapid IV Fluid Administration

Conclusions: In general, the delivery of crystalloid solutions through commonly used vascular cannulas was fastest with larger diameter and shorter length cannulas. Pressure-assisted flow was able to partially compensate for the increased resistance with smaller and longer catheters. The unique design of the tip of the Micropuncture catheter compensated for the increased length and allowed for rapid fluid delivery. This design may compensate for the increased length when longer catheters are needed for ultrasound-guided placement.
