RESUMO
5.5mmol/L),persistent metabolic acidosis,or low cardiac output syndrome.Following data were collected in all patients:time to ni- tiation and duration of PD;time point of the recovery of urine output;baseline serum creatinine level(Cr0),rise of Cr(Crl),peak Cr (Cr2),descending Cr(Cr3),recovery of Cr(Cr4);and their corresponding postoperative time points.Results Of the 63 patients,58 (92.1%)required PD.Overall mortality rate was 33.3%(21/63).Patients undergone more complex surgery requiring longer aortic damping time;have higher Cr0,Cr2,Cr3 and longer period of the recovery of Cr and urine output(P6d)was associated with more complicated surgical procedure,higher Cr1 and Cr2,delayed recovery of Cr and urine output after surgery,longer period of low cardiac output syndrome,more dysfunctional organs,longer mechanical ventilation and ICU stay postoperatively(P
