AbstractThe effects of milrinone were investigated in a porcine septic shock model. Septic shock was induced by i.v. infusion of live Escherichia coli. Anesthetized pigs were treated with milrinone before the E. coli infusion or were left untreated as septic controls. E. coli caused a significant reduction of cardiac index, renal blood flow, and portal blood flow. Pulmonary vascular resistance was significantly increased, as were the systemic and preportal vascular resistances. One of the seven septic control pigs died. In milrinone-treated septic animals cardiac index was maintained for a longer period of time but blood pressure was significantly reduced compared with the control pigs. Pulmonary vasoconstriction was little affected by pre-treatment with milrinone. Four out of seven milrinone-treated pigs died during the observation period. It is concluded that in the settings of the used porcine septic shock model milrinone treatment has no beneficial effect.
