    Abstract:
    In a prospective study, 10 children with congenital heart disease were studied before and after surgery (24-48 h). Mean age and weight, type of disease and surgery performed are described in Table 1. Six patients had acyanotic disease and 4 were cyanotic. Before surgery, the acyanotic group (AG) showed hyperuricemia compared to normal children of the same chronological age (mean +/- SE: 5.53 +/- 0.42 vs 4.27 +/- 0.22, p less than 0.02). Initial seric creatinine (sCr), increased in 3 patients of the AC and in the 4 patients of the cyanotic group (CG) compared to normal values of sCr for height (AG: 0.47 +/- 0.05 vs 0.34 +/- 0.03, p less than 0.05; CG: 0.63 +/- 0.05 vs 0.38 +/- 0.05, p less than 0.01). Post-surgery, sCr and serum uric acid (sUA) increased significantly at 24 and 48 h in both groups (Fig 1); at 24 h the increment in sUA in the AG was higher than that in the CG (p less than 0.05). There was a direct and significant correlation between the increment in sUA and sCr in the AG (Fig. 2). The urine excretion of uric acid paralleled the increment of sUA in the CG (Table 2). Fractional excretion of, sodium (FENa) was less than 1% and greater than 1% in the AG and the CG, respectively, being the basal FENa of the AG significantly lower (Table 3).(ABSTRACT TRUNCATED AT 250 WORDS)
