This month’s edition of Anesthesiology News features a worthwhile piece from Prof John Doyle, in which he poses 7 questions on the current state of airway management to 6 airway experts from around the world (Abdelmalak, Cooper, Frova, Rosenblatt, Spiegel and Doyle himself), and collates their responses into a dialogue. Definitely worth reading to determine what some (certainly not all) of the biggest names in the world are thinking on:
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:
Intubation in a young child with a severe submandibular abscess using the paediatric Bonfils rigid intubating endoscope under inhalational general anaesthesia. Direct laryngoscopy showed only severe swelling with a Cormack-Lehane grade 3b view. A standard laryngoscope was used with the left hand to create an open path for the Bonfils just right of the midline, avoiding the worst of the submandibular swelling. 3.5mm Bonfils allowed intubation with a 4.5 mm uncuffed ETT. Note that because this is a rigid intubating scope, it is not inserted through the vocal cords, but they are visible through the tube as it is inserted with the Bonfils held steady.
@fibroanestesia comes up with some interesting ideas. Here they use a combination of the AScope3 (a disposable flexible video endoscope) and the King Vision video laryngoscope to perform a highly controlled intubation in a patient with an intrathoracic goitre. They have obviously pre-assessed this patient and concluded that the risk of failed intubation or positional loss of the intrathoracic airway due to compression is minimal.
The TotalTrack is a new video laryngeal mask that allows intubation through the device without interruption of ventilation. Recruitment of the first independent clinical trial is well underway in Cape Town, with European studies nearing commencement. Here is an example video taken with the device, showing intubation in a patient with severe obstructive sleep apnoea (OSA).
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.
