Objective: One of the alternative methods in managing patients for endo-tracheal intubation is the Bonfils fiberscope. We studied the efficacy of Bonfils fiberscope in comparison to the classical laryngoscope with Macintosh blade inhemodynamic, serum catecholamine and intra-ocular pressure responses. Methods: In a prospective, randomized trial 40 patients ASA I or II aged P18 years scheduled for gynecological, urinary and lower abdominal procedures in supine position were randomly allocated to

Pre-induction (baseline) and pre-insertion values of HR, MAP, IOP and blood samples for catecholamine level were recorded and repeated at 1, 3, and 5 min after intubation. Results: There was significant increase in HR, MAP, IOP and catecholamine level in L group at 1, 3, and 5 min after intubation. Conclusion: Bonfils laryngoscope had superiority over Macintosh as a method of intubation in situations where minimal changes in hemodynamic, catecholamine level and intraocular pressure are desirable.
