Details and patient eligibility

About

The prone position is a special position often used for spinal surgery. As a special position of general anesthesia, after induction of general anesthesia, severe hemodynamic fluctuations often occur when the supine position is changed to the prone position, which seriously affects the patient's circulatory and respiratory functions.
