Maintenance fluids in prehospital care: crystalloid versus dextrose solutions--is there a difference?
D5W is the maintenance fluid often used in prehospital care when transporting patients with cardiac or central nervous system processes. However, there is evidence that dextrose solutions are potentially harmful, and that suggests isotonic crystalloid solutions are the preferred maintenance fluid in treating emergent patients regardless of their underlying disease. Dextrose solutions may exacerbate cellular ischemic damage and they cannot be used to resuscitate hypotensive patients. Crystalloids do not cause fluid overload when used at maintenance rates and are effective resuscitative agents in managing hypotension. The use of a single crystalloid solution in the prehospital environment would simplify equipment stocking and management protocols, minimize cost, and would not have an adverse impact on patient care.
