caffiene

Hey, Blee-

If I remember correctly, caffiene actually lowers the seziure threshold (makes it easier to sz), which is the goal of ECT. However, I hope some experts weigh in because it's been a little while since I've seen ECT.

I'm surprised the person administering caffiene wouldn't know, though. How strange.

Peace,

Sharon

I watched an ECT tx today and right before the CRNA injected the anesthetic, she injected some caffiene, why? I asked but didnt quite get the answer. She said something about it lowering the sedation threshold. Wouldnt caffiene do the opposite since its a stimulant? Kinda confused, please clarify, thanks guys ...

As far as lowering the sedation threshold? not sure about that. Yes caffiene and its stimulatoty effects will increase CNS stimulation but when you induce the pt is still going to go to sleep. More likely they meant decrease the seizure threshold. It is given to increase the duration of the seizure, thats what I learned, its also in Miller. Methohexital also decreases it. As opposed to propofol or thiopental that increases the threshold so requiring stronger stimuli to induce or keep the seizure going.
