Next, a magnetic instrument mat is placed overlying the patient’s upper chest. An Omni-Tract retractor is mounted to the bed at the level of mid-abdomen, opposite the surgeon. The retractor arms are placed in a wide-V configuration, over the upper body. The Ecolab Scope Pillow Warmer Drape is a clear plastic material that is stretched over the retractor arms, forming a barrier between the operative field and the surgeon, while still allowing for good visualization of the operative field. The drape is then secured with snaps to the self-retaining retractor to maintain the tightness of the drape; this will improve visibility (Fig. 1 ).
