a. After draping is completed, you will bring the Mayo stand into position over the patient.

This indicates that you are prepared to assist with the surgery. Ensure that the Mayo stand is high enough that it does not rest on the patient. Figure 3-30 shows the Mayo stand being placed into position with sufficient room between patient and stand.

b. Position the back table and ring stand at right angles to the operating table. The sterile circle is now complete (see Figure 3-31).

(1) Lay a towel for instruments below the fenestration in the drape and lay two or more sponges on this towel.

(2) Place the suction tubing convenient for the surgeon.

(3) If an electrosurgical unit is used for the procedure, attach the electrosurgical cord to the drapes with a nonperforating clamp. Ensure that ample length is provided to reach both the incision area and the equipment before dropping the end off the side of the table nearest the unit to which the circulating nurse will attach the cord. A description and use of electrosurgical units is provided in Subcourse MD0923, Introduction to the Operating Room.
