Transversus Thoracis Muscle Plane Block for Postoperative Pain in Adult Cardiac Surgery

Bilateral Transversus Thoracis Muscle Plane Block for Acute Postoperative Pain in Adult Coronary Artery Bypass Graft Surgery: A Randomized Controlled Observer Blinded Trial

Inadequate pain control after coronary artery bypass graft surgery increases mortality and results in a higher incidence of persistent poststernotomy pain syndrome. Our aim is to assess whether ultrasound-guided parasternal intercostal block (PSIB) or surgeon implied transversus thoracic muscle plane block (TTMPB) would improve the postoperative pain scores and decrease tramadol consumption better after coronary artery bypass graft surgery

Inclusion Criteria:

• American Society of Anesthesiologists physical status II-III
• Elective coronary artery bypass graft surgery under general anesthesia

Exclusion Criteria:

• American Society of Anesthesiologists physical status IV
• Emergency surgery and redo surgery
• Low cardiac output syndrome, perioperative intra-aortic balloon pump support for any reason, bleeding disorder or abnormal coagulation profile, abnormal hepatic and renal parameters, uncontrolled diabetes mellitus, chronic obstructive pulmonary disease, atrial fibrillation on anticoagulation
• Allergy to any study drugs, local infection at the block site
• Opioid abuse
