Comparing Two Ultrasound-Guided Nerve Blocks for Pain Relief in Cancer Patients Undergoing Open Kidney Surgery

What this Trial Is About

Researchers are comparing two types of ultrasound-guided nerve blocks to manage pain during and after open nephrectomy surgery in cancer patients. The study aims to evaluate the effectiveness of the external oblique intercostal block versus the subcostal transversus abdominis plane block in providing pain relief. Open nephrectomy can cause severe immediate and chronic pain, and regional anesthesia techniques are used to reduce opioid use and improve patient comfort. Participants are divided into three groups one receives the oblique subcostal transversus abdominis plane block, another receives the external oblique intercostal block, and the control group receives intravenous morphine after general anesthesia induction. Both nerve blocks involve injecting bupivacaine guided by ultrasound, aiming to cover the nerves supplying the surgical area. General anesthesia is maintained with standard medications during surgery. During the study, pain levels will be assessed 24 hours post-surgery alongside opioid and morphine consumption, heart rate, arterial pressure, time until additional pain relief is needed, and any complications. Monitoring lasts through surgery and up to 24 hours after. Participants will be closely evaluated for pain management effectiveness and safety throughout the study period.
