The purpose of this study is to examine whether spinal anesthesia affects the chances of successful external cephalic version (ECV) of a breech presenting fetus.

Two study groups will be included; one will receive spinal anesthesia, the other will not. The non-spinal group will be permitted to cross over if ECV procedure is painful.

The main outcome is success of ECV.

Primary Outcome Measures:
  • Conversion of a breech to a vertex presentation [ Time Frame: 4-6 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Complications associated with ECV: Premature rupture of membranes, Contractions, Placental abruption, Fetal distress, Pain score during procedure (VAS Scale 0 = no pain, 10 = severe pain). [ Time Frame: 4-6 years ] [ Designated as safety issue: Yes ]
  • Complications associated with analgesia: Severe maternal hypotension (>20 reduction in systolic BP), Fetal distress (prior to performance of ECV), Post Dural Puncture Headache, Failure of analgesia. [ Time Frame: 4-6 years ] [ Designated as safety issue: Yes ]
  • Inability to perform procedure due to maternal distress or discomfort. [ Time Frame: 4-6 years ] [ Designated as safety issue: No ]
  • Mode of delivery and date from the ECV. [ Time Frame: 4-6 years ] [ Designated as safety issue: No ]
