The mayo stand is a modified table The mayo stand can be adjusted in height and moved to and from

the sterile field All necessary and immediate items are placed on the mayo stand

for immediate use When moved over the patient, the bottom side is considered

contaminated due to that space being unobserved during surgery Do not place hands or items under mayo stand The mayo stand is used often and frequently May not use mayo stand on hand cases

Mayo Stand Setup Use towels to help pad mayo stand

and prevent instruments from going through mayo stand cover

Place instruments that are most likely to be used on mayo stand

Use a rolled towel to position stringed instruments on mayo stand

Close ratcheted instruments that go on mayo stand
