Abstract
Continuous veno-venous henofiltration(CVVH) and intermittent hemodialysis(HD) was instituted in 13 chronic dialysis patients duringperioperative period. Generally, HD was done within 48 hours prior to the operation, during extracorporeal circulation and the first postoperative day, and gradually recovered to the former HD program Henndynamic state was almost stable in every patient because low grade ultrafiltration was made by CVVH just after operation and there was no need for water reduction by HD. The operative time and blood loss are greater than those of non-dialysis patients, but there was no statistic difference in extracorporeal circulation time, aortic crossclarrp tine, annunt of transfused blood All patient were alive, but five had pericardial and/or pleural effusion and two had gastrointestinal henorrhage. The corrbination of CVVH and HD appears to be a safe and useful procedure for dialysis patient in the postoperative henndynamically unstable period.
