PURPOSE: To evaluate and compare the response of pigs submitted to hemorrhagic shock and treated using three different strategies. METHODS: Thirty-five Dalland pigs were divided into four groups: Control; Bleeding; Saline and Saline + Red Cell Concentrate. Parameters evaluated: heart rate (HR), mean arterial blood pressure (MAP) and central vein pressure (CVP).Hemorrhagic shock was induced by removing (624.25 + or - 64.55), (619.30 + or - 44.94) and (664.23 + or - 39.96) ml of blood respectively, with the following treatment: Bleeding Group - zero volume replacement; Saline Group - replacement with 676 ml of 0.9% saline solution; Saline + Red Cell Concentrate Group - replacement with 440 ml of 0.9% saline solution + 291 ml of red cell concentrate. The treatment was evaluated after 10 (T3), 30 (T4), 45 (T5) and 60 (T6) minutes. RESULTS: HR: No statistically significant difference was found between the Bleeding and Saline [p=1.000], Bleeding and Saline + Red Cell Concentrate [p=1.000], and Saline and Saline + Red Cell Concentrate [p=0.721] groups. MAP; Significant differences were found between all the groups studied. CVP: No significant difference was found between the groups. CONCLUSION: Non-replacement and euvolemic resuscitation maintained a satisfactory hemodynamic pattern in controlled severe hemorrhagic shock in swine. The euvolemic replacement strategies exceeded the limit values of MAP for rebleeding.
