NCT02605187

Brief Summary

The ability to predict pain and then apply modified treatment protocols has been limited. Current practice is for physicians to select standard post-operative pain treatment protocols without patient consultation. This study hopes to determine if patient's involvement in analgesic drug/dosage selection can optimize pain relief while minimizing related side effects. This could result in a more patient-centered care model and individualized perioperative analgesic treatment protocols based on patient's preferences, needs and expectations.

Outcome Measures

Primary Outcomes (2)

  • Opioid Consumption in the 0-48 Hour Study Periods.

    Opioid consumption was measured in milligram morphine equivalents in the 0-24 and 24-48 hour study periods.

    0-24 and 24-48 hour postoperative periods

  • Pain Scores

    Pain scores at rest and at movement post-cesarean delivery. Score was rated on a scale from 0 to 10, where 0=no pain and 10=worst imaginable pain.

    3, 6, 12, 24, 36 and 48 hours after delivery

Secondary Outcomes (10)

  • Count of Participants Who Need Opioid Use

    0-24 and 24-48 hours after delivery

  • Count of Participants With Presence of Pruritus

    0-24 and 24-48 hours after delivery

  • Pruritus Score at 24 and 48 After Delivery

    24 and 48 hours following delivery

  • Count of Participants Who Need Medical Treatment of Pruritus

    0-24 and 24-48 hours after delivery

  • Counts of Participants With Presence of Nausea

    0-48 hours after delivery

  • +5 more secondary outcomes
