Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To compare duration of sensory blockade To compare duration of motor blockadeTimepoint: Sensory blockade- Time interval between onset of block (T12 dermatomal level)and two segment dermatomal regression Motor blockade- Time between onset of motor blockade(Modified Bromage scal 3) to complete regression of motor block (Modified Bromage Scale 0 ) | — |
Secondary
| Measure | Time frame |
|---|---|
| Any adverse hemodynamic effects or side effectsTimepoint: Following injection of the drug intrathecally, baseline vitals will be assessed every 3 minutes for first 15 minutes & every 5 minutes thereafter till the end of procedure. Any side effects like nausea, vomiting, pruritis & sedation will also be noted;To compare onset of motor blockadeTimepoint: Time taken to reach Modified Bromage score of 3 will be assessed every 2 minutes;To compare the onset of action of sensory blockade Timepoint: Time taken to reach T12 dermatomal level assessed by sterile pin prick every 2 minutes till level reached | — |
