Is a double‐injection technique superior to a single injection in posterior subgluteal sciatic nerve block?

Bckground and objectives:  Currently, no information is available on the effects of a double‐injection technique on onset time and efficacy following subgluteal sciatic nerve blockade. We hypothesized that the success rate and time to onset of subgluteal nerve block following a double‐injection technique would be superior to that after a single injection.
