Conditions
Intervention / Treatment
Detailed 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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Total consumption of oxycodone
Time Frame: 24 hours after the end of surgery.
|
Overall use of oxycodone administered by PCA pump will be assessed.
|
24 hours after the end of surgery.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Pain intensity
Time Frame: 24 hours after the end of surgery
|
Pain intensity measured on VAS scale at the 2, 4, 8, 12, 24 hours.
VAS in milimmeters.
Minimum value 0, maximum 100.
Less better - less severe pain.
0 no pain at all.
|
24 hours after the end of surgery
|
Chronic pain
Time Frame: 6 months after the surgery
|
Chronic pain occurrence assessed with Neuropathic Pain Symptom Inventory (NPSI) 10 descriptive variables, each one from 0 to 10. 0 means no pain.
10 very high chance of occurrence of neuropathic pain.
|
6 months after the surgery
