Early neonatal outcomes of idiopathic polyhdramnios

Objective

Polyhdramnios is seen nearly 0.4%-%1.7 of the obstetric population after 24th week. About 45% of these cases etiology can not be defined. Nearly 5% of the idiopathic polyhdramios post natal structural anomaly is detected. Gastro intestinsl system, urinar system and cardiovascular system anomalies are the most seen ones. Risk of having aneuploidy is higher in idiopathic polyhdramnios. Stuides have showed that early neonatal outcomes is not well when compared with healthy one. In this study post natal anaomlies and early neonatal outcomes of idiopathic polyhdramnios were analyzed.

Methods

A case control study was conducted at Etlik Zubeyde Hanım Women’s Health Research and Training Hospital. 207 idiopathic polhydramios cases and 336 control group pregnant are included in the study. With postnatal anomaly early neonatal outcomes are also investigated. Early neonatal outcomes are defined as 5 minute apgar score, NICU admission, ventilator requirement, TTS, newborn hypoglycemia.

Results

Rate of post natal structural anomaly is higher in idiopathic polyhdramnios group when compared with control group (%5.3 vs %0.6 p=0.001). Patients with I.P. have increased rate of TTN(%1.9 vs %0.0, p=0.021), new born ressutation, (%3.4 vs %0.3 p=0.007), need for NICU (%6.8 vs %0.3 p=0.00),need for ventilator (%2.9 vs %0.0 p=0.03), new born jaundice (%6.3 vs %0.9 p=0.00) and new born hypoglycemia (%5 vs %1.2,p=0.006).

Conclusion

In idiopathic polhydramnios,although antenatal follow up do not show any abnormality postnatally, there is higher rate of having structural anomalous fetus. In our study we found that higher rate of structural anomaly at postpartum period. Although prior studies did not find higher rate of early neonatal complication, in our study we found that higher.
