To investigate the effect of peritoneal dialysis on fluid balance and outcome in childrenwho receive cardiac operation.Methods. From July to Dec. 2000, 12(2.08%) patients of 576 consecutive children who underwentheart operation required peritoneal dialysis because of acute renal failure. The mean age of these 12 pa-tients was (2.9±2.0) years (range, 5 months～7 years) and the mean body weight was (12±3) kg (range,7.4～18.5 kg ).Results. The interval between the operation and the initiation of peritoneal dialysis was (21.2±11.4)hours (4.4～42 hours). The duration of peritoneal dialysis was (6.3±4.8) days (0.47～15 days). Mortality inthese 12 patients was 25%. Fluid removed by peritoneal dialysis was(34.7±17.8) ml@kg1@day-1@ Asymop-tomatic hypokalemia, thrombocytopenia and hyperglycemia were frequent complications, which were easilymanaged. Hemodynamics and pulmonary function improved during the study period.Conclusion. The early initiation of peritoneal dialysis is an effective and safe method totreat acute renal failure after cardiac operation in children.展开更多

Methods: Forty patients with congenital heart disease (CHD, CHD group, n=20) or rheumatic heart disease (RHD, RHD group, n=20) underwent on-pump (cardiopulmonary bypass, CPB) heart-beating open heart surgery. Blood samples before CPB, and 20 minutes, 1 hour, 24 hours and 7 days after CPB were collected, and the levels of neuron-specific enolase (NSE) and protein S-100b in the plasma were determined with enzyme-linked immunoadsorbent assay (ELISA), respectively. All the patients were examined with electroencephalogram (EEG) before and 1 week after operation. The changes of NSE, S-100b and EEG compared to verify the difference of postoperative cerebral injury between CHD cases and RHD cases. Results: The plasma level of S-100b increased significantly 20 minutes after CPB and was still higher than the preoperative level at 24 hours after operation in both groups (P< 0.01). The plasma level of NSE increased more significantly in the CHD group than in the RHD group 20 minutes after CPB and it returned to the normal level 24 hours after CPB in the CHD group but remained at a high level in the RHD group (P< 0.01). The levels of NSE and S-100b returned to the normal levels on the 7th day after CPB. Abnormal EEG was found in 75% of the patients in the CHD group and 60% in the RHD group. Conclusions: On-pump heart-beating open heart surgery can cause certain cerebral injury in the patients with CHD or RHD. The injury was more severe and recovered more quickly in the CHD group than in the RHD group.展开更多
