Amnioinfusion to facilitate external cephalic version after initial failure

Obstet Gynecol. 2006 Sep;108(3 Pt 1):591-2. doi: 10.1097/01.AOG.0000230406.82713.c0.

Abstract

Objective: To evaluate the effectiveness of antepartum transabdominal amnioinfusion to facilitate external cephalic version after initial failure.

Methods: Women with a structurally normal fetus in breech lie at term, with a failed external cephalic version and an amniotic fluid index (AFI) less than 15 cm, were asked to participate in our study. After tocolysis with indomethacin, a transabdominal amnioinfusion was performed with an 18G spinal needle. Lactated Ringers solution was infused until the AFI reached 15 cm, with a maximum of 1 L. External cephalic version was performed directly afterward.

Results: Seven women participated in the study. The gestational age of the women was between 36(+4) and 38(+3) weeks, and three women were primiparous. The AFI ranged from 4 cm to 13 cm. A median amount of 1,000 mL Ringers solution (range 700-1,000 mL) was infused per procedure. The repeat external cephalic versions after amnioinfusion were not successful in any of the patients.

Conclusion: In our experience, amnioinfusion does not facilitate external cephalic version.
