Background and Methods: This study compared canine systemic hemodynamics and organ blood flow (radioactive microsphere technique) after resuscitation with 0.8% saline (Na+ 137 mEq/L), 7.2% hypertonic saline (Na+ 1233 mEq/L), 20% hydroxyethyl starch in 0.8% saline, or 20% hydroxyethyl starch in 7.2% saline, each in a volume approximating 15% of shed blood volume. Twenty-four endotracheally intubated mongrel dogs (18 to 24 kg) underwent a 30-min period of hemorrhagic shock, from time 0 to 30 min into the shock period, followed by fluid resuscitation. Data were collected at baseline, 15 min into the shock period, immediately after fluid infusion, 5 min after the beginning of resuscitation, and at 60-min intervals for 2 hr, (65 min after the beginning of resuscitation). The animals received one of four randomly assigned iv resuscitation fluids: saline (54 mL/kg), hypertonic saline (6.0 mL/kg), hydroxyethel starch (6.0 mL/kg) or hypertonic saline/hydroxyethyl starch (6.0 mL/kg). Results: Mean arterial pressure increased in all groups after resuscitation. Cardiac output increased with resuscitation in all groups, exceeding baseline in the saline and hypertonic saline/hydroxyethyl starch groups (p < .05 compared with hypertonic saline or hydroxyethyl starch). Sixty-five minutes after the beginning of resuscitation, cardiac output was significantly (p < .05) greater in either of the two colloid-containing groups than in the hypertonic saline group. After resuscitation, hypertonic saline and hydroxyethyl starch produced minimal improvements in hepatic arterial flow, hypertonic saline/hydroxyethyl starch increased hepatic arterial flow to near baseline levels, and saline markedly increased hepatic arterial flow to levels exceeding baseline (p < .05, saline vs. hydroxyethyl starch). One hundred twenty-five minuutes after the beginning of resuscitation, hepatic arterial flow had decreased in all groups; hepatic arterial flow in the hypertonic saline group had decreased to levels comparable with those during shock. Myocardial, renal, and brain blood flow were not significantly different between groups. Conclusions: Small-volume resuscitation with the combination of hypertonic saline/hydroxyethyl starch is comparable with much larger volumes of 0.8% saline, and is equal to hypertonic saline or hydroxyethyl starch in the ability to restore and sustain BP and improve organ blood flow after resuscitation from hemorrhagic shock.
