Emergence Agitation

The impact of sugammadex on agitation upon emergence following adult nasal surgeries is an issue which needs to be studied that links anesthetic management with postoperative recovery.

The included patients in the study will not be premedicated by sedatives, they will be preoxygenated for 5 minutes by 100% oxygen. The induction of anesthesia will be by fentanyl 100 microgram, 1.5 mg/kg lidocaine followed by propofol 2mg/kg, and rocuronium 0.5 mg/kg. oral intubation will be commenced and an oral pack will be inserted. Anesthesia will be maintained by sevoflurane 2% and N2O : O2 ratio of 50: 50. Hypotensive anesthesia will be conducted by labetalol 10- 20 mg i.v. At the end of surgery inhalational anesthesia will be abandoned and muscle relaxant will be antagonized either by sugamadex 1mg/kg or neostigmine 0.05 mg/kg mixed with atropine 0.02 mg/kg. After awakening of the of the patients, emergence agitation will be assessed by Agitation and Emergence Score (AES): This scale is ranging from 0 (calm and cooperative) to 4 (combative, aggressive behavior).
