ObjectivesConsidering the relation between prematurity andasphyxia and also renal failure in neonates, the aim of this study was to determine the effect of aminophyllinein urine and serum indices of renal failure and consequently its prevention, in Premature Infants with asphyxia in Esfahan-lran.MethodsIn this descriptive clinical trial study, 22 preterm neonates diagnosed with perinatal asphyxia in neonatal ward of Shahid Beheshti hospital, during 2009.The participants were randomized in two intervention and placebo groups. They randomized to receive a single dose of aminophyiline (5 mg/kg) or placebo of 5% dextrose water for injection (5 cc/kg) during the first hour of life. Renal function was assessed by GFR, beta2-microglobulin (beta2M), N-acetyl-glucosaminidase (NAG) serum creatinine and electrolytes level measurement, during the 1st, 4th and 7th day of life, in two studied groups. The results compare between the two groups before and after intervention.ResultsMean of urine output, was significantly higher in neonates who received aminophylline (P < 0.05).Mean of 132M and NAG 24 hours after intervention was not significant in the two groups of asphyxiated preterm neonates (P > 0.05).GFR was significantly higher in neonates who received aminophylline on 4th day of life (P < 0.05) and it had trend to be significantly high on 7th day (P = 0.05) and was not significantly high on 1st day (P > 0.05) comparing with control group. The most common pathophysiology of renal failure was prerenal.ConclusionAminophylline could prevent renal dysfunction in preterm neonates with asphyxia. Neonates who received aminophylin on the first day of life indicated a significant improvement in GFR and urine output.
