Brief summary
The purpose of this study is to determine if the short term use of indomethacin will reduce the number of women delivering within 48 hours when given to women with preterm premature rupture of membranes (PPROM) between 24- 32 weeks of gestation. We hypothesize that indomethacin's anti-inflammatory and tocolytic action will reduce the number of women delivering within 48 hours when given to women with PPROM between 24-32 weeks of gestation.
Detailed description
Preterm premature rupture of membranes (PPROM) is defined as rupture of the chorioamniotic membranes before the onset of labor prior to 37 weeks of gestation. The etiology of PPROM is not well understood but likely to be multifactorial. Although the underlying mechanism of PPROM is unknown, some speculate it is the human's inflammatory response to bacterial infection with the subsequent production of prostaglandins which weaken the fetal membranes. Therefore, the use of indomethacin, a prostaglandin inhibitor, may decrease prostaglandin synthesis leading to less uterine irritability and prevention of weakened membranes. This is a double blind randomized controlled trial comparing indomethacin to placebo in women with PPROM between the gestational ages of 24-32 weeks. Women between the gestational age of 24 to 32 weeks with premature rupture of membranes and not in active labor will be eligible for this clinical trial. After informed consent, patients will be randomized to either indomethacin or placebo. Maternal and neonatal outcomes will be assessed.
