Didn’t realise caffeine was used IV in anesthesia. Apparently it speeds up awakening (which makes sense to me as a non-medic). https://theanesthesiaconsultant.

But the story in OP is that the patient received caffeine IV at the beginning of the surgery (inducing severe anxiety).
Does anyone know why you would do this?
- IIAOPSW 3y agoMaybe someone put the wrong IV in?
- flangola7 3y agoEpinephrine increases the strength of painkillers. That's why there's caffeine in Excedrin.
- freedomben 3y agoI thought the caffeine was there to restrict/narrow blood vessels which usually helps with migraines. Multi-purpose maybe?
- cjbgkagh 3y agoAFAIK, I think it depends on where in the body, vasoconstriction in the head vasodilation for the rest of the body.
- etskinner 3y agoWhat does epinephrine have to do with caffeine?
- cloudwalk9 3y agoCaffeine directly kickstarts the adrenal glands

- manmal 3y agoMaybe for vasoconstriction.
- kilroy123 3y agoI had caffeine in an IV before. I was going under for surgery, and the doctor asked are you a coffee drinker? I told him oh yes, I'm a huge coffee drinker. When I woke up from the surgery, it was pretty weird. I was wide awake and alert very quickly. Never got a caffeine withdraw headache. It was awesome.
- Havoc 3y agoI know people use a similar strategy for napping. Some people (not me) can fall asleep very fast so they down a coffee and go sleep for a nap...and then wake up super fresh 30 mins later
- scns 3y agoCombined the effect is stronger than each on its own. Caffeine takes ~15 minutes to work. Sadly no source handy but i once read that naps are most effective below 15 minutes. Above it is possible to enter deeper sleep states and wake up worse than before.
- mmsnberbar66 3y agoSo when people talk about napping like this, do they ever actually "fall asleep"? I cannot possibly imagine falling asleep in 15m in the middle of my work day or whatever.
- immanentize 3y agoI've done this sort of caffeinated nap when I chugged a cup of coffee and passed out. It feels as bad as it sounds but it was effective.
- scns 3y agoI don't fall asleep. But just lying in bed, eyes closed, sleepmask on and low Binaural Beats on the ears helps me when i feel a slump. When i set a timer to 12 minutes i usually feel the urge to get up after roughly ten minutes.
