Objective: To assess the clinical role of continuous transabdominal amnioinfusion in pregnancies with preterm premature rupture of membranes (PPROM) less than 34 weeks of gestation.
Methods: In this retrospective study between January 1999 and December 2003, 76 singleton pregnancies complicated with PPROM less than 34+0 weeks of gestation, were included. Thirty-eight patients consented to undergo the continuous transabdominal amnioinfusion. The control group, matched with the amnioinfusion group by parity and gestational age at rupture of membranes, was managed expectantly.
Results: The median intervals from PPROM and delivery (latency period) (8.0 ± 7.3 days vs. 1.7 ± 2.5 days, p<0.001), the gestational age at delivery (223±17.8 days vs. 211 ± 18.0 days, p= 0.003) and the birth weight (1,853 ± 465 gm vs. 1,556 ± 459 gm, p= 0.006) were significantly increased in the amnioinfusion group compared to the control group, respectively. In maternal complications, the amnioinfusion group showed higher rate of placental abruption (5.2% vs. 2.6%, p=0.556) than the control group, but comparable in rates of cesarean section (44.7% vs. 42.1%, p=0.817) and clinical chorioamnionitis (18.4% vs. 18.4%). The rate of neonatal ventilator care of positive pressure ventilation was significantly decreased in the amnioinfusion group, compared to the control group (15.8% vs. 50.0%, p=0.002). In neonatal morbidity, respiratory distress syndrome was more frequent in the control group compared to the amnioinfusion group, although it did not show statistical significance (34.2% vs. 15.8%, p=0.06). There were no significant differences in rates of Intraventricular hemorrhage (IVH) grade III, IV, neonatal sepsis and neonatal mortality between two groups.
Conclusion: Our results suggest that, in pregnancies complicated with preterm premature rupture of membranes less than 34 weeks of gestation, the continuous transabdominal amnioinfusion might have improved the neonatal outcome without increasing perinatal infection rate.
