Trendelenburg position
Pronunciation: tren-DEL-en-burg
A surgical position where the patient lies supine with the head lower than the feet, commonly used in laparoscopic pelvic procedures.
Full Definition
The Trendelenburg position is a patient positioning technique where the individual lies supine on an operating table tilted so that the head is lower than the feet, typically at a 15-30 degree angle. Named after German surgeon Friedrich Trendelenburg, this position uses gravity to displace abdominal organs cephalad (toward the head), providing better visualization of pelvic structures during laparoscopic procedures. It is commonly used for gynecological, urological, and colorectal operations. However, prolonged Trendelenburg positioning can cause physiological changes including increased intracranial pressure, facial edema, and airway swelling.
