Why do doctors ';scrub-up'; 5+ minutes then don gloves, masks and gloves to preform surgeries?

Do surgical attendants do the same?Why do doctors ';scrub-up'; 5+ minutes then don gloves, masks and gloves to preform surgeries?
First of all the scrubbing is to eliminate all germs on hands and there is a certain way of washing the hands making sure all parts of the hands are scrubbed. Then the gloves are a protection from the bodily fluids they may come across.The gloves are a protection also from germs, and if the glove gets ripped in any way during surgery the hands are sanitized enough to not infect the patient until more gloves are put on. The mask and robe are sterile so no germs are transferred to patient. And also the scrubs they might be wearing may have germs on them to so the robe is a protection from that. The mask is so they don't breathe or sneeze on the patient.Why do doctors ';scrub-up'; 5+ minutes then don gloves, masks and gloves to preform surgeries?
well...they probably do it to get rid of any germs and other things that could cause infections. idk, educated guess.
It gets rid of bacteria, germs and anything else that can cause harmful sickness or disease. Surgical attendants do do the same thing.
This is to help prevent the risk of infections in surgery. Anyone that enters surgery is supposed to scrub up. This is an important practice in medicine to cut down on the number of problems resulting from infections.
Yes, it is done to kill germs on the hands. Then they put on sterile gloves (cuz they sren't going to operate with bare hands) and gowns and masks to maintain sterility. Don't want any one coughing into ur open wounds or shedding crud from their scrubs into open areas.
yes the whole surgical team does this, including the nurses. but not everyone in the room is scrubbed. the ones that arent scrubbed are answering phones, watching the monitors, and doing other non sterile tasks.
