Summary

Several studies demonstrated the effectiveness of OFA in patients undergoing non-cardiac surgery. Preoperative use of Cox inhibitors, GABA analogues and acetaminophen have been shown to decrease use of opioids postoperatively . Intraoperative use of agents that lead to opioid sparing effects via sodium channel blockade, blockade of G protein-coupled receptors, NMDA blockade, central alpha-2 agonists and anti-inflammatory effects can make opioid-free anesthesia (OFA) possible. On the other hand, there have been no studies demonstrating the effectiveness of an OFA technique in patients undergoing cardiac surgery except for two case reports who successfully implemented the OFA regimen in two patients undergoing valve replacement surgeries. The investigators therefore propose this prospective randomized controlled trial to investigate whether a multimodal opioid-free anesthesia regimen will be suitable as an alternative to conventional opioid-based regimen in patients undergoing valve surgery

DRUG

Fentanyl 1 mic/kg/hr

In Group II (OA) patients will receive a continuous infusion of Fentanyl (1 mic/kg/h) Morphine 0.1 mg/kg PRN will be administered every 8 hours for postoperative analgesia
