After anaesthesia and access cavity, the first root canal sample will be taken. Endodontic treatment will be completed in one visit. The second root canal sample will be taken. Patients will be asked to evaluate their postoperative pain level using VAS scale at 6, 12, 24 hours, and daily up to 5 days. Patients will record the number of analgesics if any taken.

Oxycodone consumption and postoperative pain intensity in patients undergoing nephrectomy procedures. Of all study participants, 50% will obtain quadratus lumborum block (QLB).

Comparison of two types of analgesia after cesarean section All patients will be anesthetized with spinal technique. Ultrasound-guided transversus abdominis plane or quadratus lumborum block to treat postoperative pain. Postoperative pain will be measured with visual-analog scale (VAS). 1, 2, 6 months after surgery each patient will be called to assess neuropathic pain with Neuropathic Pain Symptom Inventory (NPSI).
