The purpose of this study is to determine the best way to optimize the success of external
cephalic version (turning the baby from the outside). Attempting to turn babies in-utero is
recommended because it may decrease the risk of needing a cesarean section for abnormal
presentation. While the study team knows that this procedure can be effective, the study team
still has some un-answered questions as to the best way to perform this procedure to increase
the chance of success. Many prior studies have shown that using spinal anesthesia (a shot of
medication placed in your back to numb and relax the abdomen) can increase the success rate
of a version. This ultimately has led to the finding that using this anesthesia can decrease
the rate of cesarean section. However, there have been only a small number of studies
assessing the success rate if spinal anesthesia is used only in the event that without it
fails. Therefore the study team is going to compare patients who receive spinal anesthesia
with those who only receive spinal anesthesia if the procedure to turn the baby (ECV) fails
without it.
