Are 3 Ports Better Than One? Triple Lumen Flow Rates

There were no statistically significant differences in pressure-bag flow rates for 1L of NS through all three ports of a standard triple-lumen catheter (TLC) compared to a 16 gauge peripheral venous catheter (PVC) or a 6Fr sheath introducer.  On gravity-flow, it was not statistically different from a 16 gauge PVC.  But 14ga PVC and 8.5Fr sheath rates were superior in both instances.
