What researchers measure

Primary outcomes

  1. Pain Score on the numeric pain score

    Patients will be evaluated at 48 hours. At these time frame pain score at rest and during movement will be accessed.

    Time frame: 48 hours

Secondary outcomes

  1. Side effects as a measure of safety and tolerability

    Side effects of both interventions. Number of patients with side effects like nausea, vomiting, hypotension and pruritus.

    Time frame: 48 hours

  2. Rescue analgesic consumption.

    Opioid rescue needs in the first 48 hours after surgery.

    Time frame: 48 hours

  3. Patients satisfaction.

    Evaluation of patient´s satisfaction with pain control (asking the patient to classify the grade of satisfaction).

    Time frame: 48 hours
