Treatment and study plan

Quadro-İliac Plane Block(QİPB)

Procedure

40 mL of 0.25% bupivacaine

Primary outcomes

  1. Numeric Rating Scale (NRS) Scores

    Time frame: Postoperative 24 hours

    Description: Numerical rating scale is used for pain assessment. The scores of the numerical rating scale changes between 0 to 10 points. 10 points mean "the most severe pain that the patient ever had". 0 point means "there is no pain." Higher scores mean worse outcome.

Secondary outcomes

  1. Dermatome Area

    Time frame: Postoperative 2 hours

  2. Total tramadol consumption

    Time frame: Postoperative 24 hours

    Postoperative total analgesic need was recorded as "milligram" in unit.
