Oxycodone consumption and postoperative pain intensity in patients undergoing nephrectomy procedures. Of all study participants, 50% will obtain quadratus lumborum block (QLB).
Full description
Patients undergoing nephrectomy procedures will be allocated to one of the study arms. At the end of an operation, still under general anesthesia, 50% patients will obtain QLB with ropivacaine.
Ultrasound-guided QLB will be performed on the side of surgery with 0.375% ropivacaine solution (0.2 mL per kg).
Every patient will get patient-controlled analgesia pump with oxycodone in the postoperative period.
Postoperative pain will be measured with VAS (visual-analogue scale) 2, 4, 8, 12 and 24 hours after the end of the operation. 24 -hours period.
At the 1, 3, 6 months patients will be interviewed by phone to assess neuropathic pain. Neuropathic Pain Symptom Inventory (NPSI) will be used.
