“…Good anatomical knowledge of the intended surgical site is essential to identify and isolate major blood vessels in order to avoid iatrogenic damage to such vital structures which could result in hemorrhage, as well as employing best surgical practice in line with Halsted’s principles, which are the seven pillars of excellent surgical technique, including gentle tissue handling, meticulous hemostasis, obliteration of dead space, asepsis, preservation of blood supply, gentle tissue handling and accurate apposition of tissues [ 28 ]. Surgical preparedness is essential for responding to, and minimizing, hemorrhage where it occurs [ 28 ]. Where intraoperative hemorrhage occurs, efforts should be made to record the volume of blood lost, to monitor on-going losses and facilitate later transfusion calculations if necessary.…”
