Effectiveness of ultrasound guided Bilateral Deep parasternal intercostal block on attenuating stress response during median sternotomy in off pump Coronary Artery Bypass Graft Surgery - A prospective observational study

Median sternotomy in cardiac surgery is associated with significant intrtaopoerative pain and hemodynamic stress. Opioids are commonly used for analgesia but may cause dose dependent adverse effects such as respiratory depression and delayed recovery.

The deep parasternal intercostal plane block is an ultrasound guided regional anaesthesia technique that provides analgesia to the anterior chest wall by blocking intercostal nerves.

This prospective randomized controlled trial evaluated the effect of bilateral DPIP block on intraoperative opioid consumption and hemodynamic response in patients undergoing elective cardiac surgery via sternotomy.

The study demonstrated that bilateral Deep parastyernal intercostal block significantly reduced intraoperative opioid requirement and improved hemodynamic stability at the time of sternotomy, without significant differences in postoperative pain scores or time to extubation.

Thus, Deep parasternal intercostal blockPIP is a safe and effective opioid-sparing technique that may be incorporated into multimodal analgesia for cardiac surgery.
