Dexmedetomidine vs Dexamethasone as Adjuvant to Bupivacaine in Bilevel Erector Spinae Plane Block in Breast Surgeries

Comparison of Dexmedetomidine and Dexamethasone as Adjuvant to Bupivacaine in Ultrasound-guided Bilevel Erector Spinae Plane Block in Modified Radical Mastectomy

High percent of patients experience chronic pain following breast cancer surgeries thus proper perioperative pain control is crucial to lessen the incidence of such pain. Several techniques are adopted to control perioperative pain, these techniques include drugs as opioids and adjuvants as well as regional blocks. Erector spinae plane block is a regional technique that is used efficiently to control perioperative pain during and following breast cancer surgeries.

Erector spinae plane block is a regional technique that is used efficiently to control perioperative pain during and following breast cancer surgeries. Adding adjuvant drugs as dexmedetomidine or dexamethasone can augment the local anesthetic effect for the regional block used.
