Comparison of Two Novel Indirect Laryngoscopes to the Macintosh Laryngoscope in Patients With Cervical Spine Immobilization.

2010-07-15 17:00:00 | BioPortfolio


It is essential that anaesthetists successfully perform orotracheal intubation in scenarios in which intubation is potentially more difficult, such as where the neck is immobilized.

The Airtraq® Laryngoscope and the CMAC are new intubating devices. They are designed to provide a view of the glottis without alignment of the oral, pharyngeal and tracheal axes.

These devices may be especially effective in situations where intubation of the trachea is potentially difficult.

The efficacy of these devices in comparison to the traditional Macintosh laryngoscope in situations where the cervical spine is immobilized is not known.

We aim to compare the performances of the Airtraq® Laryngoscope and the CMAC to that of the Macintosh laryngoscope, the gold standard device, in patients in which the cervical spine has been immobilized by means of a Manual in-line stabilization of the spine.

Hypothesis: Our primary hypothesis is that, in the hands of experienced anaesthetists, time to intubation would be shorter using the indirect laryngoscopes, than using the Macintosh laryngoscope in simulated difficult laryngoscopy.

C-MAC videolaryngoscope versus Macintosh laryngoscope for tracheal intubation: A systematic review and meta-analysis with trial sequential analysis.

The C-MAC laryngoscope (C-MAC) is a videolaryngoscope that uses a modified Macintosh blade. Although several anecdotal reports exist, it remains unclear whether the C-MAC is superior to the Macintosh ...

Factors Associated with Combined Do-Not-Resuscitate and Do-Not-Intubate Orders: A Retrospective Chart Review at an Urban Tertiary Care Center.

In clinical practice, do-not-intubate (DNI) orders are generally accompanied by do-not-resuscitate (DNR) orders. Use of do-not-resuscitate (DNR) orders is associated with older patient age, more comor...

Comparison of GlideScope Video Laryngoscopy and Direct Laryngoscopy for Tracheal Intubation in Neonates.
