To study the effect of face down position during spine surgery on intracranial pressure by noninvasive method.
Not Applicable
Completed
- Conditions
- Health Condition 1: null- Patients undergoing spine surgery in prone position are at increased risk for raised intracranial pressure. These changes can be measured by sonographic measurement of optic nerve sheath diameter .
