Reading about the syndrome got my paramedic juices flowing, and I began
wondering about treatment of this in the field.  Just based on the symptoms
I wondered if some type of beta blocker such as atenolol would be of any
value.  A quick search for info yielded: (among many others)

This one had some interesting general information:

This one refers to using alpha blockers as treatment (not beta as I
theorized).

This one has a myriad of marine medical stuff on it, including the one
below:

Specifically titled "Cubozoan Jellyfish Envenomation Syndromes and their
Medical
Treatment in Northern Australia"

Interesting reading.  It recommends vinegar for neutralizing the nematocysts
(like for any other jellyfish sting), and the same alpha blocker indicated
on other sites...

Fascinating stuff.. (to me at least :-)
