Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Trendelenburg position

Group Type EXPERIMENTAL

Asana adjustment

Intervention Type BEHAVIORAL

Adjust the operating table to 15° head height and foot low in advance. The patient is then slowly turned over from the transport table to the operating table and completed in the prone position. After the patient's hemodynamic stability is smooth, adjust the operating table to the level.

Procumbent

Group Type NO_INTERVENTION
