[Hemodynamic and pulmonary effects of fluid resuscitation from hemorrhagic shock in the presense of mild pulmonary edema].
The hemodynamic and pulmonary effects of fluid resuscitation with crystalloid and colloid solutions in the presence of mild pulmonary edema were investigated. Anesthetized dogs received oleic acid to increase pulmonary capillary permeability, and one hour later bled to produce hemorrhagic shock. One hour after the shock, resuscitation was performed with Ringer's lactate, 6% hydroxyethyl starch (HES) solution, or dog's plasma. Resuscitation from hemorrhagic shock restored hemodynamics to pre-hemorrhagic levels with all of the above solutions. Ringer's lactate resuscitation resulted in increases in extravascular lung water volume (EVLWV) and oxygen consumption, and decreases in colloid osmotic pressure and oxygen delivery. Resuscitation with HES solution and plasma did not result in increases in EVLWV, but with HES solution resulted in decreases in colloid osmotic pressure to pre-hemorrhagic levels in two hours. This suggests that the resuscitation with HES solution can not maintain colloid osmotic pressure for more than two hours. The author concludes that the hemodynamic and pulmonary effects of HES solution and plasma are similar in mild lung injury cases.
