Objective: To determine the frequency and clinical significance of oligohydramnios in
patients with preterm labor and intact membranes. Study design: An amniotic fluid index
(AFI) was determined before amniocentesis (< 24 h) in 272 patients with preterm labor and
intact membranes (< 35 weeks of gestation). Amniotic fluid (AF) was cultured for aerobic and
anaerobic bacteria and genital mycoplasmas, and assayed for matrix metalloproteinase-8
(MMP-8). Non-parametric statistical techniques and survival analysis were used. Results: 1) …
