Name Time Method 1. Vertebral column length. <br/ ><br>2. Abdominal girth <br/ ><br>3. Cephalid limit of sensory block for cold[Smax(cold)] and pinprick discrimination [Smax(pinprick)] will be noted.Timepoint: Assessment will be done every 3 minutes till there is no further increase for 3 consecutive observations.
- Secondary Outcome Measures
