- Twenty-nine rats were subjected to a severe standardized hepatic injury and divided into four groups. In addition to controls, the animals were treated with PASG inflated to 40 mm Hg, PASG and infusion of Ringer's acetate, or PASG and infusion of Ringer's acetate and Dextran 70 in combination. The aim of the infusion therapy was to stabilize the mean aortic blood pressure at 60 mm Hg. PASG significantly prolonged the survival time and the time during which a sensory evoked response could be observed. The PASG also prolonged the time before the EEG amplitude began to decrease or a burst-suppression pattern appeared in the EEG. Intravenous infusion of Ringer's acetate did not prolong these times compared to when PASG was used alone; when Dextran 70 was added to the infusion therapy these times were reduced. Changes in the EEG were recorded at a mean aortic pressure of 60 mm Hg when infusions were given, whereas the aortic pressure had to fall to 40 mm Hg before any changes could be observed when no infusions were used.

- Thirty rats were subjected to a standardized critical aortic injury and divided into six groups. In addition to controls, the animals were treated with a pneumatic antishock garment (PASG), massive intravenous or intra-aortic saline infusion, or PASG in combination with either massive intravenous or intra-aortic saline infusion. Twenty-six rats were subjected to a standardized hepatic injury and divided into four groups. In addition to controls, the animals were treated with PASG, massive intravenous saline infusion, or PASG in combination with massive intravenous saline infusion. These animals were allowed to bleed for 5 minutes before the treatment was started. The treatment with PASG alone prolonged the median survival time significantly from 7 min in the control group to greater than 120 min in the PASG group in rats with an aortic injury and from 33 to greater than 120 min in rats with a hepatic injury. Intravenous infusion of saline did not prolong the median survival time. Intravenous infusion in combination with PASG did not have any positive effects on median survival time or median mean aortic pressure and failed to prolong the median survival time significantly in rats with a liver injury, as six out of eight animals developed a lethal pulmonary edema.
