The influence of aminophylline on uretic beta 2 microglobulin in neonates with asphyxia

Objective To study the renal protection of aminophylline on neonates with asphyxia. Methods 52 neonates with perinatal asphyxia were random divided into experimental group (27 cases) that receive a single dose aminophylline (5mg/kg,) intervenous drop infusion and control group (25 cases) that reveived aqua proinjectione intervenous drop infusion during the first hour of life. The urinary excretion beta 2 micr- oglobulin ( β 2M) was detected for consecutive three days after birth in neonates with asphyxia. Data from two groups were analyzed by statistics.Results There was no statistically significance difference in the levels of β 2 M at 24 hours and 48 hour after birth ( P < 0.05 ) but a statistical significance of 72h after birth (P < 0.01 ) between the experiental group and control group.Conclusios A single dose of aminophylline ( 5mg/kg ) within the first hour of birth in neonates with perinatal asphyxia results in a significant decrease in urinary excretion of β2M.
