Design outcomes

Primary

Measure	Time frame
to compare the efficacy and feasibility of 0.5% bupivacaine versus 0.75% ropivacaine in popliteal sciatic nerve block combined with adductor canal block as sole anaesthetic technique for elective ankle and foot surgeries To observe the onset and duration of sensory and motor blockade. To observe the duration of postoperative analgesia by VAS ScoreTimepoint: onset of action : every minute after administration of the drugs till 30 minutes Haemodynamic parameters : preoperatively, immidiately after administering the block, at minutes 5,10,15,30, 1hour, 2 hours,4 hours, 6hours, immidiately post operatively, 10 mkinutes, 15 minutes, 30 minutes, 1hour, 2hours, 4 hours, 6 hours. Duration of analgesia : every hour till 36 hours	—
