- Primary Outcome Measures
Name Time Method The primary objective will be to study variation in optic nerve sheath diameter (ONSD) <br/ ><br>following tourniquet inflation and deflation.Timepoint: 1. T0 - Baseline - before spinal anaesthesia <br/ ><br>2. T1 - just after tourniquet inflation <br/ ><br>3. T2 - just before tourniquet deflation <br/ ><br>4. T3 - 5 minutes after tourniquet deflation <br/ ><br>5. T4 - 10 minutes after tourniquet deflation
- Secondary Outcome Measures
Name Time Method 1) Correlation of ONSD with hemodynamic parameters. <br/ ><br>2) Correlation of ONSD with PaCO2 levels after tourniquet deflation. <br/ ><br>Timepoint: V0- Baseline vitals <br/ ><br>V1- Just after tourniquet inflation <br/ ><br>V2- Just before tourniquet deflation <br/ ><br>V3- 5 minutes after tourniquet deflation <br/ ><br>V4- 10 minutes after tourniquet deflation . <br/ ><br>Baseline paco2 before central neuraxial blockade and 5 minutes after tourniquet deflation.
