Effects of highly overdosed indomethacin in a preterm infant with symptomatic patent ductus arteriosus

Abstract

We describe a preterm infant with severe idiopathic respiratory distress syndrome (iRDS, hyaline membrane disease) who needed artificial ventilation with high inspiratory pressure, high frequencies, 100% oxygen and developed a symptomatic patent ductus arteriosus (sPDA) in the course of the disease. The infant was given indomethacin to induce constriction of sPDA. Due to an error in drug dilution the patient received a 100-fold overdose of indomethacin. Compared to the normal study protocol side-effects such as renal failure were not observed probably due to sufficient fluid intake and good clinical condition prior to treatment and to the rapid and persistent ductal closure.
