Influence of Superficial Parasternal Intercostal Plane Block on Internal Thoracic Artery Caliber to Facilitate Surgical Harvesting in CABG

Influence of Superficial Parasternal Intercostal Plane Block on Internal Thoracic Artery Caliber to Facilitate Surgical Harvesting in CABG

Influence of Superficial Parasternal Intercostal Plane Block (SPIPB) on Internal Thoracic Artery (ITA) Caliber and Surgical Harvesting Efficiency in Coronary Artery Bypass Grafting (CABG)

Parasternal intercostal blocks (PSB) represent a newer approach to post-sternotomy pain management. Studies suggest their effectiveness in providing postoperative analgesia , with a significant advantage being their suitability even during concurrent antiplatelet or anticoagulant therapy.In addition to its sympatholytic effects cause vasodilatation , a reduction in vascular resistance, and an increase in local blood flow . The effects are maintained up to the early postoperative period .

Inclusion Criteria:
