Improvement in glottic visualisation by using the C-MAC PM video laryngoscope as a first-line device for out-of-hospital emergency tracheal intubation

Abstract

Use of the C-MAC PM video laryngoscope is associated with improved visualisation of the glottis according to the Cormack and Lehane grading system and an excellent success rate for out-of-hospital tracheal intubation. These results suggest that the use of C-MAC PM as a first-line device for tracheal intubation by out-of-hospital emergency medical services is a safe procedure.

The Impact of a Soiled Airway on Intubation Success in the Emergency Department When Using the GlideScope or the Direct Laryngoscope

“…Retrospective analysis of video footage demonstrated that body fluids (blood, vomitus, or secretions) obstructing the view of the airway was negatively associated (OR = 0.29; p = 0.01) with C‐MAC intubation success. In another prehospital study, Hossfeld and colleagues evaluated the use of the C‐MAC as a first‐line device in 228 patients intubated by helicopter emergency medical service physicians. Similar to our findings, they noted a high incidence of patients with a blood or vomitus contaminated airway (29.4%), but despite this a very low incidence of lens contamination (0.9%).…”

The obstetric difficult airway: if we can't predict it, can we prevent it?

“…Having established that rapid sequence induction is indispensable in obstetric general anaesthesia, the question is whether direct laryngoscopy or videolaryngoscopy should be preferred during emergency caesarean section in a patient with anticipated difficult intubation. A robust line of evidence suggests that videolaryngoscopy is highly beneficial in a variety of settings ; because of enhanced glottic visualisation, videolaryngoscopy has a 93% success rate at the first intubation attempt in non‐obstetric patients, an overall failure rate of 1%, and functions as an effective rescue device even after failed awake fibreoptic intubation . Krom et al use a pessimistic model to predict failure of videolaryngoscopy.…”

Use of the GlideScope Ranger Video Laryngoscope for Emergency Intubation in the Prehospital Setting: A Randomized Control Trial*

“…In the prehospital setting, helicopter emergency medical service (HEMS) physicians successfully managed failed direct laryngoscopy with the GlideScope (Verathon) (14) or the video laryngoscope (C-Mac, Karl Storz, Tuttlingen, Germany) (15,16). However, randomized prehospital control trials addressing video laryngoscopy versus direct laryngoscopy are spare and limited to a single study in cardiac arrest patients.…”
