Trendelenburg position - this is the position of the patient, in which the head and shoulder girdle are located below the pelvis (Fig.). The movement of the intestine to the upper abdominal cavity that occurs during this process facilitates access to the pelvic organs during surgery. The position of Trendelenburg is achieved by lowering the head end of the operating table by 15-30 °. It is used in urological, gynecological operations, with intervention on the rectum , as well as to improve the blood supply to the brain during acute anemia (see), collapse (see), shock (see). The creation of the Trendelenburg position and the withdrawal of the patient from it are made slowly in order to avoid a sharp disruption of the activity of the cardiovascular system and the blood supply to the brain.
