A continuous infusion of vasopressin (0.06 IU/kg per hour) was started in groups V and SV at t = 300 minutes. Animals in groups C and S received intravenous saline only. ap < 0.01 time-group interaction groups V versus C: effect of vasopressin in control animals. bp < 0.01 time-group interaction groups SV versus S: effect of vasopressin in septic animals. cp < 0.01 compared to t = 300 minutes. dp < 0.05 compared to t = 300 minutes. ep < 0.05 Mann-Whitney test (area under curve): effect of vasopressin in non-septic versus septic animals. Celiac trunk: blood flow in the celiac trunk. DO2I HA: oxygen delivered by the hepatic artery. DO2I kidney: total oxygen delivered by the left renal artery. DO2I liver: total oxygen delivery to the liver. DO2I PV: oxygen delivered by the portal vein. Group C: non-septic control group. Group S: septic control group. Group SV: septic test group treated with vasopressin. Group V: non-septic vasopressin control group. Liver flow: total liver blood flow. Renal artery: blood flow in the left renal artery. | ||||
