Four patients with acute renal failure, after cardiovascular surgery were treated with hemodialysis (HD). Circulatory instability during HD is a main problem. Therefore we measured SvO2 continuously during HD as a predictor of change in cardiac output. In these of four patients, SvO2 values was higher than 65% before HD, but SvO2fell to less than 60% immediately after HD started. After 2 or 3 min-utes, hypotension was revealed. We conclude that in case of SvO2 rapidly decreased immediately after HD started, or decreased less than 60% during HD, careful manage-ment of fluid balance or use of catecholamine is necessary.
