- Primary Outcome Measures
Name Time Method Changes in the pupillometric variables within a patient over time can indicate the autonomic dysfunction. This change can be assessed preoperatively. Thus the severity of the hypotension can be predicted and necessary precautions can be taken to overcome the complications.Timepoint: blood pressure will be measured in every 5 minutes after spinal anesthesia
- Secondary Outcome Measures
