I severed my finger in the lab and have gotten it surgically reattached. I'm a heavy smoker(up to 2 packs a day) cuz phdstress and have been told to lay off it while healing due to nicotine being a vasoconstrictor and thus reducing blood flow hindering healing. This got me thinking. To what extent is medicine used to the opposite effect in modern surgery? Is pharmaceutics that increase blood flow prescribed post-surgery? And how does it work from a medical perspective? Is it just the speed of nutrient supply and waste removal?
Tell me more medfags, human biology is exciting.
