Summary

Postoperative pain is considered one of the major problems after abdominal operations, so proper pain control is one of the main issues in clinical practice. Cesarean section (CS.) is one of the most common abdominal surgeries and the use of CS. worldwide has increased to unprecedented levels. Effective postoperative analgesia enhances early recovery of the delivered mother, early ambulation, breast feeding and decreases the risk of postoperative thromboembolism. Therefore, Opioids are prescribed routinely for postoperative pain control, but they have many adverse effects such as nausea, vomiting, constipation, excessive sedation, dizziness, respiratory depression, and addiction, so it is important to practice alternative opioid sparing analgesic approaches. Recently, QL block is considered one of the perioperative pain management techniques used in patients undergoing various pelvi-abdominal surgeries. Quadratus Lumborum block inhibits both pain components (somatic and visceral) as a result of local anesthetic spread to the paravertebral spaceA study has been published comparing the analgesic efficacy between QLB and TAP block after cesarean section and proved that QL block II is more effective than TAP Block regarding pain relief and duration of action after CS. Also, Many studies have been published and prove that Combination of adjuvants like (fentanyl, clonidine and MgSo4,etc.) to local anesthetics agents helps in prolonging the analgesic effect and decrease 24hours opiate consumption.one of these adjuvants which used extensively in the regional techniques is dexmedetomidine, which is a selective alpha-2 adrenergic agonist. The optimal dosage of dexmedetomidine to be added to local anesthetics still remains unclear, but in other studies the dose of 0.5 μg/kg is widely used with no postoperative complications.

in this double blinded randomized controlled trial, the investigators compare the analgesic efficacy of adding dexmedetomidine to local anesthetic in quadratus lumborum block and their role in reduction postoperative opioid consumption after cesarean section
