- Primary Outcome Measures
Name Time Method To compare the Level of peak sensory block which is assessed at 2 minutes interval from the time of subarachnoid injection to until maximum block is acheived in patients receiving subarachnoid block with local anaesthetic hyperbaric bupivacaine 10 mg or low dose diluted hyperbaric bupivacaine 5mg for endovenous laser ablation surgery for varicose veins.Timepoint: Every 2 minutes from the time of Subarachnoid injection to until maximum level of sensory block is achieved.
- Secondary Outcome Measures
Name Time Method Any adverse events(Bradycardia,Hypotension,Respiratory distress,Nausea and Vomiting)Timepoint: End of surgery;Time to discahrge-each patientâ??s discharge eligibility using PADS score will be assessed.Timepoint: End of surgery;To compare the Degree of motor blockTimepoint: At the time when maximum level of sensory block is achieved and at the end of surgery.;To compare the duration of sensory and motor block.Timepoint: End of surgery <br/ ><br>;To compare the time to readiness for surgery(time to T12 level sensory block)Timepoint: Every 2 minutes from the time of Subarachnoid injection until T12 level sensory block is achieved.
