title: Comparison of isotonic and hypertonic fluids in resuscitation from hypovolemic shock.
abstract: Hypertonic electrolyte solutions provide effective fluids for resuscitation of burn patients and concurrent replacement of hemorrhage. Infusion of mannitol has also been advocated as a means of increasing cardiac output in acutely ill patients. Pigs which were bled to one-third of their blood volume were used in this random study of resuscitation with Ringer's lactate solution (RL), hypertonic saline solution (HSL) and RL with mannitol added (HMR) to give the same osmolality as HSL. Smaller volumes of the hyposmolar solution than of RL restored blood pressure and cardiac output. RL and HSL restored and maintained cardiac output more effectively than HMR. At 24 hours, HSL maintained blood pressure most effectively.
