Summary
The goal of this clinical trial is to evaluate and compare the efficacy, onset, duration of action, analgesic effect, and side effects of opioid-free anesthesia using dexmedetomidine and lignocaine versus conventional opioid-based anesthesia using fentanyl in patients undergoing nasal surgeries, including functional endoscopic sinus surgery (FESS) and septoplasty. The main questions it aims to answer are:
* What is the effect of opioid-free anesthesia vs opioid-based anesthesia on VAS score ?
* What is the effect of opioid-free anesthesia vs opioid-based anesthesia on postoperative complications including nausea and vomiting , postoperative Ramsay sedation score, amount of rescue analgesia , hemodynamic stability and patient satisfaction ? patients will be divided into two equal groups:
* Group OBA (Opioid-Based Anesthesia): Consisting of 30 participants, this group will receive intravenous fentanyl at a dose of 2 mcg.kg-1 three minutes prior to induction, followed by a fentanyl infusion at 0.5 2 mcg.kg-1 during the intraoperative period.
* Group OFA (Opioid-Free Anesthesia): Comprising 30 participants, this group will receive dexmedetomidine at a dose of 1 mcg.kg-1 via intravenous infusion over 10 minutes prior to induction, followed by a continuous infusion of 0.6 mcg.kg-.h- throughout the surgery. Intravenous lignocaine at 1.5 mg.kg-1 will be administered three minutes prior to induction, followed by an intraoperative infusion at 1.5 mg.kg-1h-1.
