Laryngeal Mask Airways Are Supraglottic Devices Used to Maintain Airway Patency During Anesthesia and in Difficult Airways. LMA may help in reducing postoperative pulmonary complications. IV Dexmedetomidine Improves LMA Insertion Success and Decreases trials number, While IV Lidocaine Decreases Postoperative Cough. This is a randomized interventional trial comparing both drugs. IV DEX will be compared vs IV lidocaine regarding the feasibility of insertion, number of trials, incidence of cough, postoperative pulmonary complications and hemodynamic profile.

IV 0.2 mic/ kg of dexmedetomidine will be diluted over 10 ml saline and given to the patient over 10 minutes before induction and assess the feasibility of classic LMA insertion
IV 1.5 mg/kg of lidocaine will be diluted over 10 ml saline and given to the patient 1 minute before induction and assess the feasibility of classic LMA insertion
