beta-Adrenergic agonists can enhance vascular volume expansion after a fluid bolus. The present study addresses how the beta-adrenergic antagonist esmolol influences volume expansion and fluid balance during normovolemia (series 1) and hypovolemia (series 2). Sheep were instrumented, and the spleen was removed.

We evaluated hemodynamics, metabolism, and fluid dynamics for initial resuscitation of hemorrhage using small volume 15% sodium pyruvate solution (HPY) compared with osmotically matched 8% hypertonic saline (HS). Instrumented conscious sheep were hemorrhaged 25 mL/kg at time zero through 15 min (T0-T15) and 5 mL/kg for 5 min at T50 to T55 and T70 to T75.

In this review we investigate compression of the celiac artery and the superior mesenteric artery by the median arcuate ligament (MAL), diaphragmatic crura, or the celiac nerve plexus. This clinical condition known as celiac artery compression syndrome (CACS) has proven controversial in definition and relevance.

We evaluated the extent of intestinal absorption and resuscitative effects of World Health Organization Oral Rehydration Solution after a 40% TBSA burn in anesthetized swine compared with the IV infusion of lactated Ringer's infused by Parkland formula. Plasma volume (PV) was measured using indocyanine green dye dilution.

We hypothesized that infusion of Food and Drug Administration-approved 3% NaCl provides superior cardiovascular and metabolic function while reducing the overall fluid requirement for resuscitation of hemorrhage.
