COMPARISON OF EFFICACY OF ULTRASOUND GUIDED BILATERAL ERECTOR SPINAE PLANE BLOCK AND TRANSVERSUS THORACIC MUSCLE PLANE BLOCK FOR PAIN MANAGEMENT IN PAEDIATRIC CARDIAC SURGERIES VIA MEDIAN STERNOTOMY

Postoperative pain is a side effect of a planned injury. As such, unlike physiological pain, it does not play the role of warning and defense. Instead, it leads to the development of a sequence of unfavourable pathophysiological processes triggered by nociceptive stimulation.Pain and opioids used for its relief  has been a attributable factor for prolonged ventilatory support and other side effects.  Several anaesthetic blocks have demonstrated to produce analgesia in humans undergoing median sternotomy, including neuraxial techniques, transversus thoracis plane (TTP) block, thoracic paravertebral block, erector spinae plane block, and parasternal block. In this study we propose to study transversus thoracis plane (TTP) block and erector spinae plane block in providing pain relief in paediatric cardiac surgeery patients. Along with that  other secondary objectives include to assess intraoperative and postoperative analgesic requirement, duration of mechanical ventilation, postoperative lung complications, duration of ICU stay and procedure related complications.
