Percutaneous cardiopulmonary support (PCPS) has been applied for cardiopulmonary arrest (CPA). We have developed a novel method of cardiopulmonary resuscitation using PCPS combined with liposome-encapsulated hemoglobin (TRM645) to improve oxygen delivery to vital organs. Ventricular fibrillation was electrically induced to an adult goat for 10 min. Next, PCPS (30 ml/kg/min, V/Q: 1) was performed for 20 min. Then, external defibrillation was attempted and observed for 120 min. The TRM group (n5) was filled with 300 mL of TRM645 for the PCPS circuit. The control group (n5) was filled with the same volume of saline. The delivery of oxygen (DO2) and oxygen consumption (VO2) decreased markedly by PCPS after CPA, compared to the preoperative values. DO2 was kept at a constant level during PCPS in both groups, but VO2 slowly decreased at 5, 10, and 15 min of PCPS in the control groups, demonstrating that systemic oxygen metabolism decreased with time. In contrast, the decreases in VO2 were small in the TRM group at 5, 10, and 15 min of PCPS, demonstrating that TRM645 continuously maintained systemic oxygen consumption even at a low flow rate. AST and LDH in the TRM group were lower than the control. There were significant differences at 120 min after the restoration of spontaneous circulation (p<0.05).

Foot and mouth disease (FMD) is a highly contagious viral disease of cloven-hooved livestock and wildlife results to relatively high mortality in young animals. Despite the numerous reports of FMD-related death in neonates, there is little data available on various aspects of FMD in lambs. This report describes myocarditis associated with FMD in five, one week to three months old lambs. The lambs were depressed and afebrile and two of lambs showed foamy salivation associated with shallow ulcers in oral cavity. Electrocardiography (ECG) revealed sinus tachycardia, multifocal ventricular premature beats and ventricular fibrillation. Serum biochemistry showed high levels of troponin I concentration and CK and AST activity. In Pathology, there were multiple pale areas in the subepicardial and subendocardial muscles and; widespread degeneration and coagulative necrosis of myocardium. The serum troponin I assay and ECG can be used for diagnosis of myocarditis and prognosis of affected lambs during FMD outbreak.
