Figure 2. Amniotic fluid concentrations of prostaglandins and prostamides in patients with preterm labor.
Amniotic fluid concentrations of PGE2 (A), PGF2a (B), PGFM (C), PGE2-EA (D), and PGF2a-EA (E) were determined using LC-MS/MS. Women who had an episode of preterm labor (PTL) were divided into four groups: (1) term delivery (PTL-TD); (2) preterm delivery without intra-amniotic inflammation (PTL-PTD NI); (3) preterm delivery with sterile intra-amniotic inflammation (PTL-PTD SIAI); and (4) preterm delivery with intra-amniotic infection (PTL-PTD IAI).
