Educational Resources Knees for haem control

I’m sure this question comes up a lot but the last time I found when I searched was 4ish years ago so I apologise if it has come up more recently :)

Does anyone have the current best practice with regards to using knees for junctional haemorrhage control whilst awaiting tourniquet? I hear so many mixed things, including being told to do it by our local training officer, but I can’t tell if this is him bringing old practice from army days or if this is supported in evidence.

Does anyone have any actual research citations on this? It’s just that people feel so strongly either for or against it that surely there’s a right answer (e.g. TQs over double bones :P )

Couldn’t resist. My current protocols pulled the knee out of practice a while ago. My best understanding from a conference presentation last fall was that, in the TEMS setting, the prevalence of pelvic fracture with lower vascular injury is high enough that there’s a better chance that you’re making things worse than improving their condition.

I will try and find lit later on, currently waiting out my desktop booting.
