When preparing an operating room for a patient with a hemoabdomen, the first step upon entering the abdomen will be to remove the accumulated blood to visualize the source of hemorrhage. See Figure 2.1 for suction and lavage instrumentation. In addition to the routine soft tissue instrument set, sterile suction tubing to connect to wall‐mounted or portable suction and additional suction canisters should be available, depending on the volume of fluid to be removed. A Balfour retractor will be helpful for abdominal wall retraction while the surgeon completes a thorough examination of the abdomen to identify the source of hemorrhage. Monopolar cautery and a bipolar vessel‐sealing device (LigaSure™) are helpful in controlling hemorrhage and expediting the surgical procedure.
