After preoxygenation with 100% oxygen for 3 minutes, the study drug (lidocaine) will be administered. Patients will receive 1 mg/kg lidocaine of 10 mg/mL lidocaine solution (prepared by diluting 5 mL of lidocaine 20% in saline to a total volume of 10 mL)

After preoxygenation with 100% oxygen for 3 minutes, the study drug (fentanyl) will be administered. Patients will receive 1 mcg/kg fentanyl of 10 mcg/mL fentanyl solution (prepared by diluting 100 mcg fentanyl in saline to a total volume of 10 mL).

After administration of the study drug, all patients will receive 2 mg/kg propofol intravenously

After loss of consciousness, 1 mg/kg succinyl choline will be administered over 5 seconds, and tracheal intubation will be done through direct laryngoscopy after 60 seconds.
