If you work in an environment without constant access to staff to clean and process your video laryngoscopes, you need to know how to do it yourself. This quick video demonstrates pragmatic cleaning of the C-MAC VL (original and latest version) for low-risk patients. Where there is high infection risk, heavy soiling or blood on the blades, high level disinfection may be indicated.
Some photos of the action at the Nairobi Surgical Skills Centre this week. Many thanks to the local faculty from the University of Nairobi and other institutions, the companies that supported use of the facilities and equipment, and the enthusiastic delegates!
Clinical video demonstrating a collection of techniques to facilitate elective intubation for a patient with an unstable cervical spinal injury in caliper traction. Note the sideways introduction of the VL blade due to limited space for the VL handle, optimisation of the view (‘Rule of 3’), use of a coude-tipped bougie (introducer), and the 3-part technique to advance the endotracheal tube when it catches on the arytenoid cartilage (pull tube back to disengage, rotate 90 degrees counterclockwise, advance tube).
This real-life videolaryngoscopy example (RSI of a patient with a head injury for craniectomy) shows some commom errors, and room for improvement. Three major areas that could be better to spot here:
Less-than-ideal positioning of the VL blade. The tip is too deep (over the epiglottis, rather than in the vallecula), which reduces the available space to manipulate both VL and ETT, the field of vision, and the ability to perceive the approach of the ETT.
Quick suctioning of the secretions/saliva/mucus would reduce the risk of losing the view or the patient aspirating.
An introducer (stylet/bougie) would greatly assist passage of the ETT through the cords.
A classic example of good videolaryngoscopy technique being thwarted by not always using an introducer (stylet or bougie). Note the clinician performing the intubation gets perfect, optimised VL view (Rule of 3), but then struggles to pass the ETT anteriorly enough, losing time. Although this was no problem for the well-oxygenated patient in this case (and the intubation is still under 45 seconds duration), in a critical case it can lead to desaturation, frustration, and possible intubation trauma.
Despite making a previous post and video to explain the way to make sure the device switches on, I regularly get told that the Pocket Monitor (PM) for our C-MAC video laryngoscope is not working/charging/switching on. This is in fact a design feature to prevent accidental activation or discharge. Watch here to find out more:
Thanks to the lovely Sam Adams for playing along…good career in acting if anaesthesia were to ever become boring!
Folks are frequently reporting that our C-MAC Pocket Monitor is not switching on when they plug it in to a blade and want to use it, without realizing that it automatically goes into a hibernation mode if left in the open position for more than 15 minutes. Check out this quick AirwayHowTo video on solving this problem:
This common problem is worst with small bougies, such as in this paediatric example of a child with severe burns and a difficult airway. The bevel of the ETT allows the tip of the tube to stick out right (laterally) of the bougie and snag on the right arytenoid cartilage. This can be remedied by withdrawing the ETT slightly (to disengage it from the arytenoid), effecting a one-quarter counter-clockwise rotation of the ETT on the bougie (bringing the bevel and tip of the ETT into a superior midline position snug with the bougie), and then advancing again.
