MedEd Bytes series:
MedEd Bytes is a video series that offers a quick and digestible learning format that can help solidify your understanding of different therapies leveraged in patient monitoring and respiratory interventions. In this series, we’ll cover topics such as capnography waveforms, the technology behind pulse oximetry, modes of ventilation, and more.

McGRATH™ MAC video laryngoscope
The McGRATH™ MAC video laryngoscope is proven to improve first time success rate as compared to traditional direct visualization technique,1,2 and potentially lessen hemodynamic response to intubation3,4 when compared to the traditional direct visualization technique.
In this MedEd Bytes series, we learn about the application of the McGRATH™ MAC video laryngoscope to improve intubation success.
Byte 1: Consequences of difficult intubations
Approximately 6% of intubations are difficult intubations. These difficult intubations are associated with adverse events such as oxygen desaturation, increased risk of hypertension, unexpected ICU admission, and death.5,6

Byte 2: Predicting difficult intubation
With existing methods, the majority of difficult intubations, as many as 93% of them, are unanticipated.7
02:11
Byte 3: The EMMA trial
In the EMMA trial, the McGRATH™ MAC video laryngoscope (VL) was compared to the Macintosh direct laryngoscope (DL) for routine intubation in the operating room.2

Byte 4: De Jong et al. 2022
In this study, the percent of intubations classified as a proportion of easy airway, defined as intubations with a Cormack and Lehane grades of I or II as well as absence of mask ventilation or rescue technique, increased from about 94.3% to 98.7% concomitant with the increased use of video laryngoscopy.8

Economic benefits of videolaryngoscopy
Given the additional costs associated with difficult intubations,9 the question arises: Can using video laryngoscopy as a first approach reduce the average hospital costs by avoiding negative outcomes associated with difficult intubations?
Byte 5: Introduction
Difficult intubations may be associated with increased cost, complications, and increased ICU and hospital length of stay.5,9
02:52
Byte 6: Moucharite et al.
Patients in the difficult intubation group have a mean hospital length of stay 3.8 days longer and mean ICU stay two days longer than control patients in the non-difficult intubation group.9
03:31
Byte 7: Zhang et al.
In all major diagnostic groups, video laryngoscopy was associated with a reduced likelihood of post-operative ICU admission compared to direct laryngoscopy.10
03:32
Byte 8: Thaler et al. 2021
The authors conclude that the McGRATH™ MAC VL resulted in an overall cost savings of 55% compared to the GlideScope.11
