[Therapeutic effect of early administration of oral ibuprofen in very low birth weight infants with patent ductus arteriosus].

OBJECTIVE

To study therapeutic effect and safety of early administration of oral ibuprofen in very low birth weight infants (VLBWIs) with patent ductus arteriosus (PDA).

METHODS

A total of 64 symptomatic VLBWIs (within 24 hours after birth) with PDA confirmed by bedside Color Doppler ultrasound were randomly divided into two groups: treatment and control (n=32 each). The treatment group was orally administered ibuprofen within 24 hours after birth at 10 mg/kg, followed 24 hours later by a second dose of 5 mg/kg and 48 hours later by a third dose of 5 mg/kg. The control group was treated with placebo (normal saline) at 1 mL/kg, followed 24 hours later by a second dose of 0.5 mL/kg and 48 hours later by a third dose of 0.5 mL/kg. The therapeutic efficacies and adverse effects in both groups were observed.

RESULTS

The treatment group showed a significantly higher closure rate of ductus arterious than the control group after one course of treatment (84% vs 41%; P<0.01). The incidence rates of periventricular leukomalacia and bronchopulmonary dysplasia were significantly lower in the treatment group than in the control group (P<0.05). The duration of mechanical ventilation and mean hospitalization time were significantly shorter in the treatment group than in the control group (P<0.05). There were no significant differences in the incidence rates of intraventricular hemorrhage, early pulmonary hemorrhage and necrotizing enterocolitis between the two groups (P>0.05). No obvious adverse effects were observed in both groups.

CONCLUSIONS

Early administration of oral ibuprofen for treatment of PDA in VLBWIs can decrease the incidence rates of some early complications and shorten hospitalization time, but causes no significant adverse effects.
