An Experimental Study of Warming Intravenous Fluid in a Cold Environment Timothy F. Platts-Mills, MD, Eric Stendell, MD, Matthew R. Lewin, MD, PhD, Micheal N. Moya, BA, Kulraj Dhah, BA, Geoff Stroh, MD, Marc Shalit, MD Wilderness & Environmental Medicine Volume 18, Issue 3, Pages 177-185 (September 2007) DOI: 10.1580/06-WEME-OR-051R1.1 Copyright © 2007 Wilderness Medical Society Terms and Conditions

Figure 1 Pictures showing a, intravenous fluid bag with heat pack attached; a coil of intravenous tubing is between the heat pack and the intravenous fluid bag; b, intravenous fluid bag with coil, heat pack, and insulating fleece jacket attached, ready for infusion; and c, 500-mL bag of fluid on stove with temperature probe on bag.

Figure 2 Temperature vs time for trial 1 of methods 10 (2 Meal Ready to Eat [MRE] packages on 500mL), 11 (2 MRE on 500mL for 10minutes, then fluid removed from heat source), and 14 (stove heating 500mL to 75°C, then fluid removed from heat source). Time zero represents the beginning of the infusion. Delays of 1) 6minutes, 15 seconds; 2) 11minutes, 5 seconds; and 3) 8minutes, 20 seconds occurred prior to infusion for methods 10, 11, and 14, respectively. Note the spikes in the temperature associated with method 10 at the beginning (58°C) and the end (52°C) of the infusion.
