Olukman O et al. – Oral ibuprofen therapy is as efficacious as intravenous ibuprofen with some concerns about increased sepsis and bronchopulmonary dysplasia incidence. However, comprehensive and large–scale pharmacokinetic studies are required in order to prove this efficacy. On the other hand, intravenous ibuprofen still remains to be the drug of choice for patent ductus arteriosus but only with meticulous control of serum sodium levels in smaller infants.
Methods- This is a single–center retrospective study.
- Data were collected from patients' files of preterm infants who were hospitalized at the Neonatal Intensive Care Unit of Dr. Behcet Uz Children's Hospital between April 2009 and June 2010.
- Six hundred sixty infants were evaluated by echocardiography between 24 and 48 postnatal hours.
- Clinically and hemodynamically significant ductus arteriosus was defined in 66 infants with gestational age less than 32 weeks and birth weight less than 1500 g.
- Oral or intravenous ibuprofen (loading dose: 10 mg/kg on day 1, followed by maintenance dose: 5 mg/kg on days 2 and 3) was administered.
- Treatment success was defined as a completely closed duct without reopening on follow–up.
- Drug–associated renal, gastrointestinal, cerebral, hematological, and metabolic side effects were monitored and compared between treatment groups.
- Ductal closure rates were 100% and 97.6%, respectively, in the oral and intravenous groups.
- Hypernatremia was the remarkable side effect in the intravenous group, whereas bronchopulmonary dysplasia and septicemia were prominent in the oral group.
- No statistically significant difference could be demonstrated between the groups in terms of mortality rates.
