Why Choose the McGRATH™ MAC Video Laryngoscope? Dr. Karen Phillips Explains.

About the Author

Dr. Karen Phillips MD, FCA, MBA is an anesthesiologist, adult intensivist, and senior medical director at Medtronic.

Traditional laryngoscopy has a learning curve, which disadvantages the novice or inexperienced intubator. The reason for that learning curve is that the clinician is required to create a straight line of sight for visibility of the larynx and the vocal cords. This often requires manual manipulation of the airway, and sometimes a bit of force.

The McGRATH™ MAC video laryngoscope places the clinician's eyes at the end of the blade, imparting the ability to see around the curvature of the tongue, and this translates to less tissue manipulation.

The McGRATH™ MAC has a number of features, which help maximize your first attempt intubation success. Improved optics, four times more pixels in the camera, a brighter LED, and a wider field of view enable a crisp, clear image of the anatomy.* The handle and blade design mimic that of the traditional Macintosh direct laryngoscope handle, so there's no change in muscle memory.

There are significant benefits to having a McGRATH™ MAC reusable handle and disposable blades. There is the convenience of always being ready. There is no need for the device to be removed from the area of care between patient use in order to be sterilized. Disposable blades are more cost effective and also remove the need for repeated device sterilization, but without sacrificing patient safety. And a wide range of disposable blade sizes means that patients of all sizes can be intubated.

The features of the McGRATH™ MAC also help keep clinicians safe. Better airway visibility and an unchanged laryngoscopy technique enable clinicians to have higher first pass intubation success. This can result in a reduction in the time spent performing laryngoscopy, minimizing the time over an open mouth, and lessening the potential for droplet transmission.1,2

There are significant benefits to having an attached or integrated video screen compared to a remote screen. A remote screen removes the focus away from the airway, and the clinician needs to move their eyes and head in order to introduce adjuncts, direct assistant hands, or even orientate themselves in the mouth. With an integrated screen, the patient becomes the center of a wider field of the clinician vision.

We know that difficult intubations are often unanticipated. The McGRATH™ MAC has been shown to have the highest rate of intubation success when compared to other video laryngoscopes.3
