Clinical analysis of cardiac arrest in 5 cases during liver transplantation / 中华器官移植杂志

ABSTRACT

Objective To analysis the causes of cardic arrest during liver transplantation, and investigate the preventive measures. Methods Clinical records about 5 patients with cardiac arrest in liver transplant were studied retrospectively. Results Occurrence of cardiac arrest was 2.1 % (5/240). All the events happened at 3-6 min after graft reperfusion, and arrest lasted 3-8 min. Two patients died of resuscitation failure. After graft reperfusion, CVP and MPAP were much high in 5 patients. All of them had hypothermia and hypocalcemia. Three of them also had acidosis and two complicated with hyperkalemia. In one case, the difference between PaCO_2 and P_ETCO_2 was 47 mm Hg. Conclusion Many factors, such as disturbances of electrolyte and acid-base equilibrium or hypothermia, seemed to have some contribution to cardiac arrest occurrence after reperfusion. Various methods should be used to counter it.
