Open nephrectomy incision is associated with a high incidence of intense immediate postoperative pain and chronic pain the months following surgery. Regional anesthesia techniques are commonly recommended for pain management in open nephrectomy as they decrease parenteral opioid requirements and improve patient satisfaction. Rhomboid intercostal subserratus plane block (RISS) is considered a novel approach for chest wall and upper abdominal analgesia, initially showed promising results, first reported in 2016. Erector Spinae Plane block (ESB), was initially described in 2016 for analgesia in thoracic neuropathic pain. It has also been widely used in both adults and children at different levels for different indications. Epidural analgesia is the gold standard for perioperative analgesia in open surgery. Epidural analgesia-related significant complications can include epidural hematoma, postoperative neurologic deficit, and post-dural puncture headache, and anesthesiologists are searching for alternative analgesic modalities that have adequate analgesia and a lower complication risk.
Our aim is to measure the efficacy of rhomboid intercostal subserratus plane block and erector spinae plane block in comparison to thoracic epidural block in patients undergoing open nephrectomy
