Supine Position

The supine position /ˈsuːpaɪn/ is a position of the body: lying with the face up, as opposed to the prone position, which is face down, sometimes with the hands behind the head or neck. When used in surgical procedures, it allows access to the peritoneal, thoracic and pericardial regions; as well as the head, neck and extremities.

Using terms defined in the anatomical position, the dorsal side is down, and the ventral side is up.

The supine position is used with the patient‘s head neutral or rotated for frontal, temporal, or parietal access. Extremes of head rotation can obstruct the jugular venous drainage, and a shoulder roll can combat this problem. The head is usually in a neutral position for bifrontal craniotomies and for transphenoidal approaches to the pituitary. The head-up posture is best accomplished by adjusting the operating table to a chaise lounge (lawn chair) position (flexion, pillows under the knees, slight reverse Trendelenburg position). This orientation, in addition to promoting cerebral venous drainage, decreases the patient‘s back strain.
