I was honoured to be invited back on the Critical Care Scenarios (@icuscenarios) podcast, to chat this time about airway management in COVID-19, but also talking about how it’s helping to focus improving our emergency airway management in general. Check it out at this link:
A description of the technique for intubating through a supraglottic airway that offers a sufficiently large internal bore to allow an appropriate-sized endotracheal tube using an adult fibreoptic or flexible video endoscope. Take note of the method of providing ventilation during the endoscopy!
As usual, this is an unscripted video, and constructive critique is welcomed to help us improve the educational offering.
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:
Without getting into a lengthy argument about what constitutes a second-generation supraglottic airway (or an extraglottic vs. supraglottic, for that matter), if you are using an SGA with a gastric drainage port (such as the LMA Proseal, LMA Supreme, i-Gel, etc) you have a very simple and easy conduit to insert a mid-oesophageal thermistor probe to monitor patient temperature.
Ideally, to achieve a mid-oesophageal position, you need the probe to extend 5-10 cm past the tip of the SGA, so try and remember to measure the probe against the device before insertion and mark it with a small piece of dressing tape. This has an added advantage of helping prevent air leak via the drainage tube if your SGA is not seated or strapped ideally. Of course, this means that drainage via the oespophageal lumen is significantly impaired, and you cannot insert a gastric tube without removing the probe first, so it is only suited to patients in whom you have little concern regarding reflux and aspiration. Devices that offer twin drainage tubes (such as the 3gLM) are a way around this problem.
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).
