Why during surgery doctors wears mask on their mouth?

Is there any odor during operations?Why during surgery doctors wears mask on their mouth?
It's is for infection control. The mask does NOTHING to prevent you smelling the various odors that can permeate an OR.





Electrocautery burns flesh, and burning human flesh smells nasty. It's nothing, though, compared to infarcted bowel. That will stink up an entire OR suite. When that happens, we put something better smelling on the inside of our masks (oil of wintergreen, or benzoin).Why during surgery doctors wears mask on their mouth?
as the 2 above said it is for the sake of not getting bacteria into the body of the patient. It is vital that this done also because the patients body is open and bacteria can get around ALOT quicker internally when you dont have your skin as a main deffence.











As for your second question.





none that i herd of...unless i guess if they're working on the blowels....ewwww
The doctors who are performing an operation wear a mask to prevent germs that they breathe out from entering the operating room.They don't want that to happen because if they enter an area opened for surgery,the wound has the possibility of becoming infected.
To keep everything as sterile as possible.





So the doctors don't breathe germs on the patient.





So spit or the un-expected sneeze doesn't


hurt the patient.

so they don't breathe germs into the surgical site and put foreign particles in the air during surgery
to prevent the spread of infection.


and there could be odor if it involves cauterization.
so that they won't give off germs when they talk. spits come out of their mouths and it will go inside the patients body. Or sometimes its for them so that they won't breathe germs from the patient
It is to prevent the doctor from breathing germs from their mouth/nose into the patient.
