Management of Oligohydramnios with Antepartum Amnioinfusion, Amniopatch and Cerclage

Summary 

Objective

To evaluate the efficacy and safety of aggressive management of oligohydramnios.

Methods

Forty women with oligohydramnios (< 30 complete weeks), either because of preterm premature rupture of membranes or with intact membranes, were prospectively enrolled in this study. Eleven women were assigned to the treatment group and 29 to the control group. Transabdominal amnioinfusion was performed with warm Ringer's lactate or normal saline in all 11 patients in the treatment group. In addition, cerclage was performed in patients with ruptured amniotic membranes. Amniopatch was used to salvage a patient with immediate amniorrhea (< 6 hours) after the above procedures.

Results

Nine of the 11 patients prolonged their pregnancy for at least 3 weeks (81.8%), while all 29 patients in the control group delivered their babies within 3 weeks of diagnosis of oligohydramnios (p < 0.05). Signs of maternal infection were noted in two patients in the treatment group (18.2%). The newborns of eight patients in the treatment group survived beyond 1 month (72.7%), whereas this occurred in only six control patients (20.7%; p < 0.05).

Conclusion

Aggressive management seemed to provide prolongation of pregnancy compared with no treatment. Amniopatch salvaged the immediate amniorrhea in our patient.
