The effect of an external counterpressure device (ECPD) on hypertonic saline treatment of uncontrolled hemorrhagic shock (UCHS) was studied in rats. The rats were divided into five groups. In group 1 (n = 11) UCHS induced by incision of three radicals of the ileocolic artery was treated by 5 mL/kg NaCl 0.9% (normal saline). In group 2 (n = 20), UCHS was treated by 5 mL/kg NaCl 7.5% (hypertonic saline). In group 3 (n = 6), UCHS was treated by inflation of ECPD to 50 torr. In group 4 (n = 7), UCHS was treated by ECPD and normal saline; in group 5 (n = 9), UCHS was treated by ECPD and hypertonic saline. Incision of the ileocolic artery in group 1 rats led to a fall in mean arterial pressure to 33 torr (P less than .001) followed by a spontaneous rise to 48 torr (P less than .01) with a mortality rate of 27% and a mean survival time of 161 +/- 9 minutes. Infusion of hypertonic saline during UCHS was followed by a further fall in mean arterial pressure to 18.5 torr (P less than .001); mortality was 80% within 80 minutes with a mean survival time of 35.5 minutes, which was significantly lower than in group 1 (P less than .01). Inflation of ECPD during UCHS in group 3 or treatment with ECPD and normal saline in group 4 did not alter the hemodynamic response and mortality, which were similar to those of group 1.(ABSTRACT TRUNCATED AT 250 WORDS)

D005676	Gravity Suits	Double-layered inflatable suits which, when inflated, exert pressure on the lower part of the wearer's body. The suits are used to improve or stabilize the circulatory state, i.e., to prevent hypotension, control hemorrhage, and regulate blood pressure. The suits are also used by pilots under positive acceleration.
