About

The objective of this study is to compare the effects of TTPB vs PIFB on postoperative opioid consumption in patients undergoing open cardiac surgery.

Full description

Cardiac surgery performed through median sternotomy is associated with significant postoperative pain.Poststernotomy pain leads to decreased patient satisfaction, delirium, cardiovascular complications (hypertension, tachycardia, arrhythmias), hyperglycemia and respiratory complications (bronchial secretion stasis, atelectasis and pneumonia).High-dose opioids can provide good postoperative analgesia for patients undergoing heart surgery. However, opioids have some side effects.The advent of ultrasound-guided regional anaesthesia led to the development of fascial plane chest wall block as transthoracic plane block and pectointercostal fascial block.
