Design outcomes
Primary
| Measure | Time frame |
|---|---|
| dermatomal increase in maximum sensory block produced by epidural volume extensionTimepoint: Every 2 minutes, the sensory level will be assessed till 3 consecutive identical readings are obtained (before and after the epidural volume extension). | — |
Secondary
| Measure | Time frame |
|---|---|
| motor blockadeTimepoint: same as sensory level monitoring to attain grade of maximum motor block. | — |
