Operation or indomethacin for the premature ductus
LH Edmunds Jr
Indomethacin constricts the patent ductus arteriosus in approximately 70%
of premature infants, but temporarily inhibits synthesis of all
prostaglandins. Early toxicity of indomethacin is not prohibitive, but the
possibility of late neurological deficits is raised by results of
laboratory experiments. As yet, no late toxic effects of indomethacin have
been observed. However, this possibility and the low morbidity (less than
2%) and mortality (less than 2%) of surgical ligation of the patent ductus
arteriosus in premature infants favor operation except in carefully
controlled and limited clinical trials.
