There are a range of high quality laryngoscopes available to assist with airway management. They are manufactured from high quality materials with a lifetime guarantee. These devices can be used by both health professionals and patients for a variety of purposes.
A good high quality laryngoscope will provide excellent illumination and visualisation, helping to ensure patient safety during the procedure. It will also be durable and strong to withstand repeated use.
The type of laryngoscope blade and the design of the device influence its performance, and should be considered when evaluating which to use. Typically, curved blades are easier to insert into the mouth and provide better visibility of the larynx. Straight blades tend to be less bulky and allow for independent manipulation of the tracheal tube within the oral cavity.
Channelled Video Laryngoscopes
There are two basic types of video laryngoscopes: those that work like a conventional laryngoscope and those that have a channel integrated into the blade to guide the endotracheal tube. Both types of laryngoscopes have advantages and disadvantages. They may be helpful, or they may not be, depending on the clinical needs of the operator.
Some of the major differences in performance between these two types of laryngoscopes are based on the blade's shape, curvature, and position of the video camera. A standard laryngoscope works by loading the endotracheal tube into a stylus and then guiding it into place with the blade tip. A channelled laryngoscope relies on the exact positioning of the video camera in front of the glottic opening to improve intubation success.
Various laryngoscope blade designs have been developed in recent years, including those that include both LED light and a CMOS camera eye. These designs are easier to insert into the mouth and reduce the risk of injury from accidental burns.
These designs have a lower price point and are often more affordable than the higher priced video laryngoscopes. They are also easier to clean.
A number of these devices feature a reusable monitor that attaches to disposable blades to reduce the risk of cross infection and the need for multiple replacements. Some of these designs also feature anti-fog mechanisms.
One of the main benefits of a video laryngoscope is that it can increase the effectiveness of intubation, especially with difficult airways. This is because the therapist can observe the position of the larynx and guide the tracheal tube through it. This increases the chances of success and reduces the risk of complications.
Other important advantages of a video laryngoscope are its ability to reduce intubation time and its ease of use. This makes it a more practical tool than the classic Macintosh blade and may lead to fewer failures, particularly in understaffed hospitals.
Several studies have shown that video laryngoscopes are more effective than conventional Macintosh blades in patients with limited mouth opening or inhibited neck movement. However, most of these studies are not conclusive and should be interpreted with caution.
