Breech Presentation during Pregnancy
External cephalic version for breech presentation: A randomised controlled trial of anaesthetic interventions
External cephalic version for breech presentation: A randomised controlled trial of anaesthetic interventions
Our objectives in this prospective randomised blinded control study are to compare the outcome and effects of using (A) intravenous analgesia or (B) spinal anaesthesia for primary and reattempts of ECV at term. Secondary objectives are comparisons of the effects on the fetus, mechanical forces used, pain and side effects during ECV. The conclusion will define the role of using IV analgesia and spinal anaesthesia for ECV, and establish guidelines that are not available in current literature.
