Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate and compare the onset times and success rates of ultrasound guided popliteal sciatic nerve block done by two different techniques: 1) separate injections around tibial and common peroneal branches distal to the bifurcation, and 2) single injection around the sciatic nerve proximal to its bifurcation.Timepoint: Block progression is assessed every 3 minutes till complete blockade for onset time. Success rate is observed at the end of surgery. | — |
Secondary
| Measure | Time frame |
|---|---|
| To compare the block procedure time, post-operative pain & incidence of adverse events associated with ultrasound guided popliteal sciatic nerve block done by separate tibial & common peroneal branches injections compared to injecting proximal to the bifurcation.Timepoint: Block procedure time is from USG probe preparation to deposition of local anesthetic. Post-operative pain is assessed at 2 hours, 4 hours & 8 hours post block procedure. Adverse events are assessed immediately, 1 hour, 4 hours & 8 hours post block procedure. | — |
