Bilateral Ultrasound Guided Pectoralis Nerve Block Induces Hemodynamic Stability With Reducing Systemic Stress Response for Adult Patients Undergoing Off-pump Coronary Artery Bypass Graft
In Brief
A Early Phase 1 clinical trial evaluating Bilateral Ultrasound Guided Pectoralis Nerve Block. for Analgesic Effects and 2 related conditions. Completed, enrolled 40 participants across 1 site.
Detailed Summary
Opioids used in attenuation of the neuroendocrine stress response in patients undergoing off-pump coronary artery bypass graft (OPCAB) it produces predictable satisfactory analgesia and sedation but with side effects such as respiratory depression, drowsiness, and myocardial depression. Regional techniques may be encouraged to be anti-stress procedures and produce risk-free postoperative (OPCAB) period. Pectoralis nerve block (pecs block) appears to possess a great deal of promise for patients undergoing (OPCAB) because of low complication rates as it is less invasive regional analgesic technique when compared to paravertebral, thoracic epidural analgesia and parenteral analgesia.

Timeline
Interventions
Using a 20-gauge 5 cm needle. Injection bupivacaine 0.25% used as a local anesthetic. The block was performed in a supine position with the arm slightly abducted. The ultrasound probe was placed at the midclavicular level infero-laterally to locate the axillary artery and vein and then moved laterally toward the axilla until pectoralis major, pectoralis minor, and serratus anterior muscles were identified at the level of the fourth rib. The needle was inserted in-plane with respect to the ultrasound probe. A volume of 20 ml of local anesthetic solution was deposited in the fascial plane between pectoralis minor and serratus anterior muscle, followed by withdrawal of the needle to the fascial plane between the pectoralis major and pectoralis minor muscle, where a volume of 10 ml was deposited. The block was performed similarly on the opposite side. Care was taken not to cross the toxic dose of bupivacaine (3 mg/kg).
