    AbstractWe measured cervical spine movement during orotracheal intubation in 16 anesthetized patients without neck injury. Comparisons were made using straight and curved laryngoscope blades without stabilization, Philadelphia collar stabilization, and in-line stabilization by an assistant. There was cervical spine movement in all cases. There was no significant difference in movement without stabilization when comparing straight and curved laryngoscope blades (P = .8536). There was no significant decrease in movement when a Philadelphia collar was applied (P = 1.000). There was a significant decrease in movement when in-line stabilization was applied (P = 0.0056). Although none of the methods tested totally prevented cervical spine movement during orotracheal intubation, the least movement was obtained by the use of in-line stabilization by an assistant. The type of laryngoscope blade used or application of a Philadelphia collar did not reduce movement significantly.
