Abstract
The effects of IABP on renal function were studied in 31 patients with cardiac diseases. Blood and urine samples for the renal function were taken before and during IABP. Patients were dikided into three groups according to the responses within 6 to 12 hours of IABP. In Group I (20 cases) which showed the significant improvement of renal and cardiac function, the values of Ccr, CH2O, FENa improved to normal range within 6 hours after initiation of IABP, and the value of Renin—angiotensin II—aldosterone recovered within 24 hours. In Group II (3 cases) with improved renal function and impaired cardiac function, these parameters of renal function improved after 12 hours. In Group III (8 cases) with impaired renal as well as cardiac function, there were no improvements in these parameters. In conclusions, IABP was effective therapy for the patients with cardiogenic shock, LOS and renal dysfunction. The patients who showed improvement of renal function within 12 houres after initiation of IABP could be easily weaned from IABP. However, the patients in whom the renal dysfunction persisted beyond 12 hours of IABP, could not be weaned from IABP.
