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 .
Conditions
Interventions
Intervention1: Effect of two different prone position on optic nerve sheath diameter in patients undergoing spine surgery: Patients will be randomized to either of the two arms based on the computer g

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1) To study the effect of prone position on ONSD in patients undergoing spinal surgeries. 2) To study the effect of reverse trendelenburg of 10 degree on the changes of ONSD.Timepoint: 1) Before surgery 2) During surgery 3) After surgery | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) Changes in the optic nerve sheath diameter at different patient positions over the course of surgery. 2) Changes in the hemodynamic parameters at different patient positions over the course of surgery Timepoint: 1) Supine position (TB) 2) After 10 minutes of prone positioning (TP) 3) After 2 hrs after prone positioning. 4) Every 1 hr till the completion of surgery ( T2,T3,T4,T5 and so on) 5) Immediately turning the patients to supine (TES) 6)30 minutes post surgery after giving 30 degree of head elevation (TE30) | — |
