[Peritoneal dialysis following open heart surgery in children].

From 1982 to 1991, 13 (3.9%) of 336 children who underwent open heart surgery required peritoneal dialysis postoperatively, including 5 with transposition of the great arteries, 4 with tetralogy of Fallot, 2 with ventricular septal defect, 1 each with atrioventricular canal defects and total anomalous pulmonary venous connection. Patients ages ranged from 12 days to 4 years (mean, 1 year and 4 months). The infusion catheter was directed toward diaphragm from the right lower quadrant, and the drainage catheter was placed in the pelvis from the left upper quadrant. Dialysis solution was instilled and drained simultaneously. Seven children (54%) recovered renal function, with six (46%) longterm survivors. Differences between patients who did and did not recovered renal function (Group A and Group B respectively) were examined. No significant intergroup difference existed in age or weight. PD was initiated significantly sooner in Group B (1.2 +/- 0.8 days) than in Group A (3.2 +/- 1.9 days) (p < 0.05). The negative fluid balance was 88.0 +/- 31 mL/kg/day in Group A and 78.4 +/- 25.0 mL/kd/day (NS). BUN and serum creatinine concentrations were slightly elevated in both group, but were not significant different. Patients in Group A were dialyzed from 3 days to 21 days (mean 9.9 +/- 6.4 days), and patients in Group B were dialyzed from 1 day to 14 days (mean 5.3 +/- 5.2 days) (NS). The central venous pressure (CVP) in Group A decreased while blood pressure (BP) and renal perfusion pressure (RPP) increased following initiation of PD. CVP increased in Group B, while BP and RPP decreased. All patients died of low cardiac output syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)
