Design outcomes

Primary

MeasureTime frame
Compare the Incidence of unintended sciatic nerve block with two different volumes of ropivacaineTimepoint: 1)Spread of drug to the sciatic nerve confirmed with ultrasound 2)Signs of motor or sensory involvement in the ditribution of sciatic nerve in the first 24 hrs after surgery

Secondary

MeasureTime frame
1)Time of block would be taken as time zero,time of first analgesic requirement would be calculated in minutes from this point 2)Total demand of analgesics in 24 hours would be noted 3)The quality of pain relief would be assessed by NPRS numeric pain rating scale 4)Patients satisfaction was assessed by a three point scale excellent, satisfactory and unsatisfactoryTimepoint: 1)Time of block would be taken as time zero,time of first analgesic requirement would be calculated in minutes from this point 2)Total demand of analgesics in 24 hours would be noted 3)The quality of pain relief would be assessed by NPRS numeric pain rating scale 4)Patients satisfaction was assessed by a three point scale excellent, satisfactory and unsatisfactory
