On the part of dentists, I will say that teeth sometimes smell terrible, especially in cases where the crown is completely destroyed and only roots remain. The same when removing a crown from a tooth - the smell of light rot, rotten stuff
The smell of blood, it is the smell of blood. So ... salty, some sort of raw. When using a coagulator, a fried smell appears - shchashlyk-mashlyk). In the purulent department, the smell is cold, you can sometimes go in and hit the air, it is so dense there. But to be honest, all this is tolerable. It is worse when patients do not wash, do not change their clothes (we are talking about those who can. No complaints about the bedridden)
The smell depends on the reason why everyone is actually going to cut a person.
If we are talking about abdominal surgery associated with damage to the gastrointestinal tract, then the smell is appropriate: digested, even partially, food does not give off like lilies of the valley.
If we are talking about purulent operations, such as opening phlegmon, etc., then the smell is generally understandable. If you are unlucky (or lucky) and you are a teenager suffering from acne, then as you squeeze one pimple somewhere on your forehead, bring its contents closer to your nose. Mentally multiply by an arbitrary number depending on the size of the abscess. Voila.
If we are talking about pure operations, then in general it does not smell anything special. What does raw meat smell like? Well, something like this.
When something is done to the body, its smell can change. When drilling a bone, for example. And the smell of freshly fried meat is carried through the operating room in the case of electrocoagulation, because muscles are literally fried.
