Abstract | UNLABELLED: In rats subjected to closed head trauma (CHT) plus uncontrolled hemorrhage, giving 0.3 mL of 0.9% saline per 0.1 mL of blood lost did not restore mean arterial blood pressure (MAP) or improve neurological severity score (NSS). In CHT without hemorrhage, giving 20% albumin or 10% hetastarch improved NSS. We hypothesized that these latter treatments would also improve NSS after CHT plus uncontrolled hemorrhage. Rats were randomly assigned to one of seven groups. Experimental conditions were CHT (yes or no), uncontrolled hemorrhage (yes or no), and fluid given to replace blood loss (none; 10% hetastarch, 20% albumin, or 3% saline [0.1 mL per 0.1 mL of blood lost]; or 0.9% saline [0.3 mL per 0.1 mL of blood lost]). NSS (0--25 scale, where 0 = no impairment) was determined at 1, 4, and 24 h, and brain water content was determined at 24 h after CHT. NSS (median +/- range) at 24 h was 11 +/- 6 when no fluid was given; 16 +/- 5 with 10% hetastarch; 14 +/- 5 with 20% albumin; 12 +/- 4 with 3% saline; and 13 +/- 4 with 0.9% saline given (not significant). In addition, brain water content and MAP did not differ among the groups receiving CHT with or without uncontrolled hemorrhage. In our model of CHT plus uncontrolled hemorrhage in rats, giving 10% hetastarch, 20% albumin, 3% saline, or 0.9% saline failed to improve NSS, brain water content, or MAP. IMPLICATIONS:
