[Chronic hemodialysis in children].
BACKGROUND
The final objective of every children that is admitted to a program o hemodialysis of peritoneodialysis is to receive a renal graft.


OBJECTIVE
To report the experience in pediatric hemodialysis in two pediatric hospitals in Chile that are reference centers for renal transplantation.


METHODS
Sixty patients, 55% female, aged 2 to 15 years old, admitted to the dialysis and transplant program since 1987, with a creatinine clearance of less than 20 ml/min/1.73 m2, were studied.


RESULTS
Twenty percent of children were less than 5 years old at the moment of admittance to the program and 3.3% weighed less that 10 kg. Etiologies of end stage renal disease were glomerulopathies in 33.4%, reflux nephropathy in 27.7%, obstructive uropathy in 13.3%, hypoplasia/dysplasia in 10%, hereditary problems in 8.3% and vascular disorders in 5%. Eighty six percent of patients were dialyzed less than 2 years and 5% more than 4 years. Fifty percent had received prior medical treatment, 5% had been treated with intermittent peritoneal dialysis, 5% with chronic ambulatory peritoneal dialysis and 20% presented as a terminal renal failure. Sixty two percent received a renal graft, 25% is still on hemodialysis, 3.3% switched to chronic ambulatory peritoneal dialysis, 3.3% had a recovery of renal function and 6.7% died being on hemodialysis. Arterio-venous fistulae were the vascular accesses in 75% of patients, double lumen catheters in 50% and vein grafts in 5%. Malfunctioning or infections were the main complications of arterio-venous fistulae, accounting for 30% of hospital admissions.


CONCLUSIONS
The availability of new vascular accesses and new hemodialysis machines specially designed for children, along with specially trained health care personnel, should reduce the mortality and complication rates of hemodialysis in this age group.
