NCT01931215

Brief Summary

Analgesia after cesarean section is still not satisfactory for many women. Even if pain reduction is sufficient with the technique of intrathecal morphine injection, side effects such as nausea and pruritus are common. Since several years, an alternative technique has been studied, the "transversus abdominis plane (TAP)"-block. Here a local anesthetic is injected in the abdominal wall muscles, and this has been shown to give a similar analgesic effect compared to intrathecal morphine, with potentially less side effects. With this study, we want to evaluate if the TAP-block yields indeed less side effects when compared with intrathecal morphine. The study will be a prospective study with the patients randomized to either a group with intrathecal morphine or a group with TAP-block.

Outcome Measures

Primary Outcomes (1)

  • cumulative incidence of nausea and/or vomiting at 24 hours

    Data for this endpoint will be gathered at 6h and 24h postoperatively from nurses' records in the recovery room (at 6h) and on the ward (at 24h), and counterchecked by asking the patient

    24 hours

Secondary Outcomes (12)

  • Cumulative incidence of pruritus at 24h

    24 h

  • Cumulative incidence of treated nausea and vomiting at 24h

    24h

  • Cumulative incidence of sedation at 6 and 24h.

    24h

  • Cumulative incidence of arterial hypotension

    24h

  • Cumulative incidence of bradycardia

    24h

  • +7 more secondary outcomes
