Several times prior to surgery I have been amazed at the rapid effect of the anesthetic being delivered in my vein. In a recent answer to a question concerning the volocity of blood, it was given as 10 cm/second, and that was in a major artery.I would guess that in order to reach my brain from my arm, it would take a count of 10 to 15 for ne to pass out...but I have seldom gotten past 4 or 5.
Re: How does an anesthetic act so fast when introduced into a vein?
