Primary Outcome Measures :
  1. Pain Score on the numeric pain score [ Time Frame: 48 hours ]
    Patients will be evaluated at 48 hours. At these time frame pain score at rest and during movement will be accessed.

Secondary Outcome Measures :
  1. Side effects as a measure of safety and tolerability [ Time Frame: 48 hours ]
    Side effects of both interventions. Number of patients with side effects like nausea, vomiting, hypotension and pruritus.

  2. Rescue analgesic consumption. [ Time Frame: 48 hours ]
    Opioid rescue needs in the first 48 hours after surgery.

  3. Patients satisfaction. [ Time Frame: 48 hours ]
    Evaluation of patient´s satisfaction with pain control (asking the patient to classify the grade of satisfaction).
