Core Tip

Core tip: In goats subjected to exsanguination-induced hypovolemia and tourniquet-imposed hindlimb ischemia-reperfusion, intravenous resuscitation with Ringer’s lactate produced marked electrocardiographic instability, lipid peroxidation and inactivation of the critical creatine kinase system, which supplies energy for membrane ion transport. In comparison with lactated Ringer’s, resuscitation enriched with the natural antioxidant and energy substrate pyruvate stabilized cardiac rhythm, prevented lipid peroxidation, preserved creatine kinase activity and augmented myocardial energy reserves. Importantly, these favorable effects persisted for at least 3.5 h after terminating pyruvate-enriched resuscitation. Thus, pyruvate-enriched resuscitation prevented creatine kinase inactivation by oxidative stress, thereby preventing cardiac rhythm disturbances after central hypovolemia.
