In which surgical position is the patient's head lower than their torso?

The Trendelenburg surgical position is characterized by the patient's head being lower than their torso. This position involves tilting the table so that the patients' feet are elevated above their head, which can enhance venous return to the heart and is often used in surgeries of the pelvis and lower abdomen.

In this position, the downward tilt can be beneficial in some surgeries, as it helps to elevate the abdominal organs and provides better visualization for the surgeon. The Trendelenburg position is commonly utilized in emergencies, such as in cases of hypotensive patients, to increase blood flow to vital organs.

Conversely, the supine position has the patient lying flat on their back, while the prone position involves the patient lying face down. The lateral position has the patient lying on their side. These other positions do not involve the head being lower than the torso, making them unsuitable answers for the question.
