Rhomboid intercostal block (RIB) and Rhomboid intercostal block with sub-serratus plane block (RISS) are the two types of plane blocks used for postoperative analgesia after abdominal surgeries. For achieving proper postoperative analgesia, multimodal regimens have been described for patients undergoing abdominal procedures like cholecystectomy. These multimodal regimens could include opioid medications, non-opioid analgesics (e.g., acetaminophen and ketorolac), and regional blocks. These modalities could be used alone or in combination. This prospective randomised controlled trial was performed to analyse the postoperative analgesic effects of ultrasound guided Quadratus lumborum block and RISS block in managing post operative pain in patients undergoing open nephrectomy.
