OBJECTIVE: To compare the effectiveness of remifentanil for pain management in external version.

PATIENTS: Pregnant for 36 weeks or more with breech presentation who met the inclusion criteria and sign the consent. Participants will be randomized into two groups before the procedure.

Group intervention: paracetamol and remifentanil Control group: paracetamol and placebo DETERMINATIONS: VAS pain level, percentage of success of the maneuver and adverse events.

Statistical Analysis: Comparison of pain recorded by VAS in both groups and comparison of adverse events
