Manual In-line Stabilization Increases Pressures Applied by the Laryngoscope Blade during Direct Laryngoscopy and Orotracheal Intubation.

The article discusses a study regarding assessing the measure applied pressures distributed along the length of the laryngoscope blade during direct laryngoscopy and intubation and to evaluate the effect of manual in-line stabilization (MILS) upon these pressures. It reveals that DL with MILS results in increasing applied pressure compared to conventional DI. It concludes that pathologic cranio-cervical motion has the potential to increase in the presence of cervical instability, impaired glottic visualization and secondary increases in pressure application.
