EDITORIAL: PDF OnlyA New Device For Rapid Fluid ReplacementREETER, ALAN K. M.S.E.E., CCE; ISERSON, KENNETH V. M.D., FACEP Author Information Section of Emergency Medicine University of Arizona Health Sciences Center Tucson, Arizona Journal of Clinical Engineering: January 1984 - Volume 9 - Issue 1 - p 37-42 Buy Abstract The authors designed an intravenous infusion system providing flow rates approximately four times greater than the fastest commercial systems. The system incorporates a number 14 French (4.5 millimeter internal diameter) catheter, introduced via the Seldinger technique, and a specially designed fluid manifold. The manifold, designed and built by the authors, allows fluid from five separate IV bags to flow to the patient through one line. Flow rates of normal saline during in vitro tests were greater than 850 mL/min. under gravity and 2.0 L/min under pressure. Packed red blood cells (PRBC) with 90% hematocrit flowed at 800 mL/min. under pressure. PRBCs diluted to 42% hematocrit flowed at 1725 mL/min. under pressure. In vivo tests with dogs demonstrated gravity and pressurized flow rate of approximately 650 mL/min. and 1600 mL/min. normal saline, respectively. No unusual sequelae of the large bore catheter were detected in the veins. ©1984Aspen Publishers, Inc.
