The multiple trauma patient often presents hypothermic. The infusion of warmed parenteral fluids is one of the least invasive methods of core rewarming the hypothermic patient. This study discusses and describes a safe, efficient method of warming normal saline and lactated Ringer's solution by microwave radiation. ⋯ The technique involved midcycle (60 seconds) interruption with agitation and end-cycle agitation. Intra- and extrabag temperatures were confirmed with three separate thermometers. It was concluded that by following the recommended protocol, hospital personnel could be taught this safe method of rapidly warming nondextrose containing crystalloid.
