Treatment of symptomatic polyhydramnios with indomethacin.
Polyhydramnios carries a poor fetal prognosis with an expected neonatal death rate of nearly 30%. Approximately one-fourth of this perinatal mortality is a result of the effects of prematurity. The poor outcome with usual management of polyhydramnios led us to introduce the therapeutic use of prostaglandin synthetase inhibitors so as to decrease amniotic fluid volume and to prevent premature labor. Twenty-two women (20 singleton and two twin pregnancies) were included in a retrospective study from 1983 to 1992. Indomethacin was given at a dose of 3 mg/kg/day. Treatment was started at 28.2 +/- 3.8 weeks of amenorrhea and discontinued after 35 weeks. We observed a significant effect of indomethacin on amniotic fluid volume and avoided severe preterm delivery in all patients. Mean gestational age at birth was 37.5 +/- 1.6 weeks of amenorrhea (range 35.5-39 weeks). We did not observe any maternal or neonatal side effects of indomethacin therapy. However, we reported three neonatal deaths out of 24 infants: two related to undiagnosed fetal anomalies (one Nager syndrome and one cerebral malformation) and one related to umbilical cord entanglement in a monoamniotic twin pregnancy. Since our first report, several open studies supporting our data have been published. However, although indomethacin appears to be effective in the treatment of polyhydramnios, our goal is to analyze efficacy and side effects, so as to define conditions of clinical use.
