Table 2. Time to Perform Block and Onset Times (min)

Total onset time was defined as the time to obtain a total sensory and motor block after injection (tibial, peroneal, posterior cutaneous). Total block time was defined as the time elapsed from the beginning of the procedure (insertion of the needle through the skin) to a complete sciatic sensory and motor block. Values (in min) are medians (5th–95th percentiles).
