What researchers measure

Primary outcomes

  1. Postoperative Pain

    Postoperative pain will be measured using a Verbal Rating Scale (0-10) Verbal Rating Scale: 0 to 10 scale where 0 indicates= No pain" and 10 indicates= The worst possible pain

    Time frame: 3 days

Secondary outcomes

  1. Opioid Consumption

    Opioid consumption obtained from the recorded data Perioperative use of opioid consumption inside hospital (recorded by study staff and data obtained from patient charts)

    Time frame: 3 days

  2. Length of Analgesia

    Time in days and/or hours

    Time frame: 3 days

  3. Patient Satisfaction With Regional Nerve Block

    Patient satisfaction with regional nerve block: measured using a Verbal Rating Scale (0-10) Verbal Rating Scale: 0 to 10 scale where 0 indicates= No satisfied at all 10 indicates= Extremely satisfied

    Time frame: 3 days

  4. Patient Satisfaction With Pain Management

    Patient satisfaction with pain management: measured using a Verbal Rating Scale (0-10) Verbal Rating Scale: 0 to 10 scale where 0 indicates= No satisfied at all 10 indicates= Extremely satisfied

    Time frame: 3 days
