Can we start a new learning thread since the last one has been closed? There was a lot of good information. I would like to keep that going!

Here is something I learned just the other night regarding the oculocardiac reflex. A patient presenting with orbital trauma with a positive oculocardiac reflex (a triad of nausea, bradycardia (which can lead to asystole!) and syncope) can be indicative of entrapment of the inferior rectus muscle. The "pulling" of the inferior rectus muscle when the patient is told to look up or move their head causes a vagal response. This is a true emergency.

Any other takers?

In all my years of nursing, never used cocaine in practice. Didn't know it was still in a pharmacy and used.

Made our own 'TAC', the PA mixed it and applied. But thought that was neat.
