Introduction: Central venous access has been a matter of choices. Should it be a triple lumen for fluids, a wide-bore for infusion, or an introducer for a pulmonary artery (PA) catheter? A new cannula from Baxter now offers one the option of a single device to accomplish multiple functions with one stick. The object of this study was to compare maximal flow rates of this new device with a traditional 9F introducer, utilizing the Haemonetics Rapid Infusion System (R.I.S.). Methods: Devices tested were the Baxter Advanced Venous Access device (AVA model M3L9F) which incorporates a 9F PA access with one distal (D) and two proximal lumens (P1&P2); and an Arrow 9F introducer (model SI-09903-E). Fluids measured were Normal Saline and a Blood/Plasma mixture. The RIS was set up in a manner to continually infuse fluids through the device tested, using a cut-off pressure of 300 mmHg to judge maximum flow. Devices were tested with PA catheters (7.5F & 8F). Results for the AVA are shown in various configurations: AVA(1)=D+P1; AVA(2)=P1+P2; AVA(3)=D+P1+P2. Results: Flow rate results are below: (Figure Presented) Conclusion: In all categories, the Advanced Venous Access device delivered higher flows than the Arrow 9F introducer. Compared to previous triple lumen flow rates, the AVA device delivers significantly higher flows. Therefore, the AVA device offers a new dimension in central access for trauma, critical care, and high blood loss surgeries (i.e., liver transplants). It now gives us the ability to monitor the circulation and infuse fluids with fewer venous punctures.
