Abstract

OBJECTIVE
The aim of this study was to evaluate the peripartum efficiency of amnioinfusion in oligohydramnios without preterm premature rupture of membrane.
METHODS
73 singleton pregnant women with oligohydramnios were enrolled in this study. Women with preterm premature rupture of membrane were excluded. 21 women were treated with transabdominal amnioinfusion 31 times and 52 women were closely observed without amnioinfusion. Mean amniotic fluid index, mean gestational age, mean maternal age and the parity at the time of diagnosis was not statistically different in both groups.
RESULTS
Mean amounts of infused artificial amniotic fluid was 536ml (200-700), the mean time consumed was 61(+/-39.2)min. After infusion, mean amniotic fluid index was increased significantly from 4.2(+/-1.6) to 10.0(+/-2.9). But we found no statistically significant differences in pregnancy outcomes. The outcomes are as follows 1)Mean gestational age at birth was 36.3(+/-3.5) weeks in amnioinfusion group and 37.2(+/-2.9) weeks in control group. 2) Mean birth weight was 2.54(+/-0.9)kg versus 2.51(+/-0.8)kg. 3) The proportions of poor Apgar score at 1 minute and 5 minute were not significantly different. 4) Cesarean section rate was 0.79 versus 0.65. 5.There were two still births in both groups.
CONCLUSION
Transabdominal amnioinfusion in oligohydramnios has little effects in improving longterm pregnancy outcomes.
