Condition anticipated difficult airway
Treatments lingual traction, sham, fiberoptic intubation
Sponsor Enrico Camporesi
Start date June 2012
End date September 2013
Trial size 78 participants
Trial identifier NCT01958346, Pro00008289


We propose the additional technique of lingual traction or "tongue pulling" in conjunction with use of the flexible fiberoptic bronchoscope for facilitating successful first attempts at and decreasing time to intubation of the difficult airway and rescuing otherwise failed intubation attempts. Induction of general anesthesia causes relaxation and approximation of the soft palate, base of the tongue, epiglottis, and posterior pharyngeal wall, creating unfavorable anatomic changes in the pharynx for successful intubation. The use of lingual traction can assist in diminishing these problems by clearing the tongue away from the soft palate and uvula and lifting the epiglottis from the posterior pharyngeal wall, especially in the unanticipated difficult airway patient.

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking open label
(Sham Comparator)
Standard of care fiberoptic intubation without any additional experimental maneuvers
fiberoptic intubation
lingual traction
The tongue pulling maneuver consists of grasping the tongue with 4x4cm gauze and gently pulling the tongue out until resistance is met.
