Brief Summary

Nearly 50% of patients suffer from chronic pain following breast cancer surgery. Several regional anesthesia techniques, including paravertebral block, erector spinae plane block, pectoral nerves block, and serratus anterior plane block, have been applied for acute pain control and prevention of chronic pain after breast cancer surgery. Exploiting the beneficial effect of glucose in regulating neuroinflammation and neuropathic pain, we hypothesize that the addition of glucose to bupivacaine could be superior to bupivacaine in ultrasound-guided SAPB in improving the quality of postoperative analgesia and preventing chronic pain after mastectomy. Patients will be randomly allocated into one of two equal groups (30 patients each ); the study group; Group I( B-D) (n=30): will receive unilateral USG-deep SAPB 0.4 ml/kg Of 0.25 % isobaric bupivacaine with addition of 15ml glucose 5% to (30 ml total volume); Group (B-N) (n=30): will receive unilateral USG-deep SAPB 0.4 ml/kg Of 0.25% isobaric bupivacaine to be diluted with 15ml isotonic saline (30 ml total volume). The occurence of postmastectomy pain, 3 months after surgery, will be the primary outcome.

    24 hours

  • The severity of CPSP and its impact on daily function

    3 and 6 months after surgery
