To compare ease of oral intubation using flexible fibreoptic bronchoscope with or without rigid cervical collar, in terms of need of maneuvers: Jaw thrust and Chin lift.

25 patients in age range 20-50 yrs, of ASA І-II, and of either sex undergoing elective surgery under general anaesthesia were randomly allocated into each group. There were two groups: Group A (Rigid Cervical Collar) and group B (Without Collar). Intubating condition was assessed in between these groups with need of manoeuvres like jaw thrust and chin lift.

There was significant (p <0.05) difference between group A and group B in terms of use of manoeuvres for ease of intubation and clearing upper airway. In group B need of jaw thrust and chin lift for clearing airway is significantly (p <0.05) higher than collar group.
