A methodology to evaluate motion of the unstable spine during intubation techniques

Spine (Phila Pa 1976). 1993 Oct 15;18(14):2020-3. doi: 10.1097/00007632-199310001-00015.


Airway management in patients with an unstable cervical spine remains a challenge. A video fluoroscopic technique that transfers the image to a floppy disk for direct measurement is described. This technique enabled standardized, direct measurement of the cervical spine during airway maneuvers before and after a C5-6 posterior instability was surgically created in five cadaveric specimens. Unsupported direct oral techniques often can cause more motion than do indirect nasal techniques, and chin lift/jaw thrust and cricoid pressure can cause as much motion as do some of the intubation techniques.
