In this second episode of two, Ed turns his attention to the use of adrenaline in TCA, and in ROSC (return of spontaneous Circulation), when to cease resuscitation and what TCA management might look like in the future
Top 3 Points from this podcast:
- The first is a reiteration from Richard Lyon, which is to know and practice the HOT algorithm – I find a good way to remember the actual components is: oxygenate, decompress, and fill. This gives you an immediate action drill when under stress.
- TCA is not futile, but the way that data are reported makes it seem that survival is similar to medical arrest – this is unlikely to be the case, and almost all of the patients who are truly in TCA pre-hospital will be pronounced life extinct at the scene.
- Form a mental model of when you would and would not perform closed-chest compressions – discuss these with colleagues and during training. The time to get this right in your head is not when faced with a TCA. This can be a very difficult situation pre-hospital in terms of working together / human factors; the default is to deliver chest compressions whilst reducing risk to rescuers.
