QLB After Nephrectomy

July 17, 2018 updated by: Michał Borys, Medical University of Lublin

Effectiveness of Quadratus Lumborum Block After Nephrectomy

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

Study Overview

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
