Neurological and electroencephalographic changes in newborns treated with prostaglandins E1 and E2

Area of Science:

• Neonatal cardiology
• Pediatric neurology
• Pharmacology

Background:

• Obstructive right heart lesions in newborns necessitate interventions to ensure adequate pulmonary blood flow.
• Maintaining ductal patency with prostaglandin (PG) is crucial for survival in neonates with specific congenital heart defects.

Purpose of the Study:

• To evaluate the neurological and electroencephalographic effects of prostaglandin E1 or E2 in newborns with obstructive right heart lesions.
• To assess the safety and efficacy of different routes of PG administration.

Main Methods:

• Neurological and electroencephalographic examinations were performed on six newborns receiving intravenous or intraarterial PG.
• Patients were treated to maintain ductus arteriosus patency and enhance pulmonary blood flow.

Main Results:

• All patients showed increased arterial oxygen saturation.
• Electroencephalograms indicated mild sedation; three neonates experienced transient neurological abnormalities (myoclonic jerks, apnoeic spells, hiccup) with intravenous PG.
• Neurological side-effects resolved upon discontinuation of PG therapy.

Conclusions:

• Prostaglandin therapy is useful and safe for managing ductal-dependent heart lesions in neonates.
• Intraarterial administration of PG may be preferable to minimize central nervous system side effects.
