Summary
Brief summary (as posted)
To compare efficacy and safety of adding thoracic paravertebral nerve blocks to modified PEC block versus modified PEC block only in breast cancer surgery. This study evaluate systemic opioid requirement in 48 hours in primary outcome and the analgesic profile ( pain score at rest and on shoulder movement), opioid-related side effects and nerve blocks complications.
