The McGRATH™ MAC video laryngoscope features five sterile, disposable blade size options to support pediatric to adult patients, routine and difficult airways: McGRATH™ MAC blades size 1 and 2 are for smaller patients, feature a Macintosh style curvature, and are designed for routine use.
The McGRATH® MAC Video Laryngoscope (McGRATH® MAC or the device) is a tool used to aid the intubation of the trachea.
In the MVL group, McGrath MAC 4 disposable laryngoscope blade was used for intubation, following manufacturer's instructions. [23] The patient's mouth was opened and the laryngoscope blade was inserted into the right side of the mouth, the device was moved to a central location, sweeping the tongue to the left.
The most common laryngoscope blade used for intubation in adults is the curved Macintosh blade (Figure 34-4). This is inserted into the right side of the mouth to displace the tongue laterally. The tip of the blade sits in the vallecula and is lifted forward to elevate the epiglottis and expose the laryngeal inlet.
Curved Blades: Examples include the #10 and #15. These are excellent for smooth, sweeping cuts and are commonly used in general surgeries.
Many articles have published reports that the use of a Miller blade enables better visualization of the glottis than the use of the Macintosh blade [16]. Authors suggest that less tissue needs to be displaced to obtain an adequate view of the glottis when using the Miller blade.
A bougie is a thin plastic rod that is passed into the trachea, over which the endotracheal tube is inserted. Historically, most emergency tracheal intubations in the US have been performed using a stylet, with use of a bougie reserved for difficult intubations.
Tracheal intubation (TI) is a common procedure in critical care, often performed with a Macintosh curved blade used for direct laryngoscopy (DL).
Direct laryngoscopy is a crucial medical procedure that involves using a laryngoscope to directly visualize the vocal cords and the entrance to the trachea. This technique is essential for performing tracheal intubation, commonly required in anesthesia and emergency settings to secure the airway.
In its simplest form, the endotracheal tube is a tube constructed of polyvinyl chloride that is placed between the vocal cords through the trachea. It provides oxygen and inhaled gases to the lungs and protects them from contamination, such as gastric contents or blood.
The use of a defective McGRATH™ MAC video laryngoscope may result in patient harm, including failed laryngoscopy and/or intubation, potentially resulting in respiratory failure (including hypercarbia), hypoxia (leading to bradycardia, dysrhythmias), hypercapnia, tissue damage/tissue trauma and/or a delay to treatment ( ...
Medtronic recommends that McGRATH™ MAC video laryngoscopes be cleaned and low-level disinfected using a sequence of 70% IPA or equivalent wipes. The first cycle should clean and de-soil the device, followed by a second cycle to disinfect the exposed surfaces.
Disposable blade options
McGRATH™ MAC blades size 1 and 2 are for smaller patients, feature a Macintosh style curvature, and are designed for routine use. McGRATH™ MAC blades size 3 and 4 are for adult patients, feature a Macintosh style curvature, and are designed for routine use.
Description. The Miller laryngoscope is a straight blade designed to obtain a view of the vocal cords by directly lifting the epiglottis. It has useful application in 'floppy' airways making it popular within paediatric anaesthesia. The Miller laryngoscope is the most commonly used blade today.
The Macintosh laryngoscope has a curved blade which allows exposure of the larynx by positioning the tip in the vallecula, anterior to the epiglottis, lifting it out of view.
The 3-3-2 rule involves measuring 3 different distances in the patient's neck using the clinician's fingers. These measurements aid in predicting the ease or difficulty of intubation. Additional tools such as the LEMON scale and the Mallampati scoring system also play a valuable role in the evaluation of the airway.
The McGRATH™ MAC video laryngoscope is a device that combines the benefits of both direct laryngoscopy (DL) and video laryngoscopy (VL). DL - familiar technique of a Macintosh direct laryngoscope. VL - video laryngoscope technology.
The major takeaway is that intubation is a high-risk procedure reserved for certain situations. It requires specialized knowledge and skills by a qualified medical professional. Even advanced nurses with specialty certifications must stay current on evidence-based practice and care standards.
Surgical blades come in sterile packaging and the number on a surgical blade communicates both its size and its shape. Some common types and numbers of blades include the following: The #10 – A large curved cutting edge, which represents a more traditional blade shape.
Carbon Steel: Known for their sharpness and precision, carbon steel blades are the preferred choice for surgeries demanding high precision. These blades are also a cost-effective choice for disposable scalpels.
Scalpel is an essential dermatological tool used “for making skin incisions, tissue dissections, and a variety of surgical approaches since the onset of 'modern' surgery.” Scalpel blades come in different sizes, identified by a blade number, and each serving a different purpose.
