Abstract
Prostaglandin E1 (PGE1) has been used for decades in the medical treatment of ductal dependent critical congenital heart disease in neonates. The article is a report of a retrospective evaluation of the long-term effects of PGE1 in a neonatal intensive care unit in Saudi Arabia. There were 22 subjects with a wide spectrum of cardiac defects maintained on PGE1 for a mean of 38 days (range: 6-200 days). The majority of the complications included hypokalemia, hypotension, and apnea/bradycardia. Pseudo-Barett syndrome and gastric outlet obstruction were also found. While long-term administration of PGE1 is rare in North America, it is important to be aware of possible adverse effects of fluid and electrolyte imbalance, gastric outlet obstruction, and feeding difficulties.
