N2 - We have previously demonstrated that the administration of recombinant human interleukin-11 (rhlL-11) during resuscitation improves the blood pressure in a rodent model of hemorrhagic shock. The purpose of this study was to determine whether the effects of rhlL-11 could be reproduced in a large animal model and to elucidate the impact of rhlL-11 administration on the intravascular volume status and the degree of third space fluid loss after resuscitation. A 40% blood volume hemorrhage was induced in swine (n = 45, weight of 25-35 kg) followed by a 1 -h shock period and resuscitation with 0.9% sodium chloride (three times the shed blood volume). The animals were randomized to receive sham hemorrhage (group I, sham); sham hemorrhage and 50 μg/kg rhlL-11 (group II, sham + IL-11); no drug (group III, saline); or 50 μg/kg rhlL-11 (group IV, IL-11). Blood and urine samples were obtained and analyzed at baseline, at the end of hemorrhaging, and thereafter once every hour. The pleural and peritoneal effusions were precisely quantified by using clinically accepted criteria. The mean arterial pressure (MAP) was higher postresuscitation (PR) in groups I, II, and IV (71.4 ± 7.5 mmHg, 71.0 ± 8.9 mmHg, and 72.9 ± 12.3 mmHg, respectively) than in group III (59.9 ± 10.9 mmHg), and the cardiac output of PR was higher in group IV (3.46 ± 0.56 L/min) than in group III (2.99 ± 0.62 L/min; P < 0.01). The difference in MAP between groups I and II became statistically significant at 40 min after rhlL-11 injection and such a difference persisted for 90 min. After resuscitation, the urine output was higher, and the urine specific gravity and third space fluid loss were lower in group IV (1434 ± 325 mL and 1.0035, 82 ± 21 mL) than in group III (958 ± 390 mL and 1.0053, 125 ± 32 mL; P < 0.05). In a porcine model of hemorrhagic shock, the administration of rhlL-11 at the start of resuscitation significantly improved the cardiac output and blood pressure. This strategy also significantly reduced the extent of third space fluid losses while also having a favorable impact on the intravascular volume status as evidenced by the improved urine output.
