BACKGROUND AND OBJECTIVES: The midfemoral @entity1930 (MF) is a new technique that has been used for postoperative @entity1337 after knee surgery. The aim of the present study was to compare efficacy, performance time, and @entity1 acceptance of the midfemoral approach to that of the lateral approach at the level of the popliteal fossa (popliteal block [PB]). METHODS: Sixty-three @entity1 were enrolled in this prospective, randomized study. Thirty-two @entity1 received a lateral sciatic @entity616 (group PB) and 31 @entity1 a @entity616 (group MF). @entity1342 0.5% (30 mL) was used in both groups. RESULTS: The quality of nerve blockade was comparable in both groups. Onset of sensory block for peroneal and tibial nerves was significantly shorter in group MF than in group PB, 5 (1-20) minutes and 5 (1-20) minutes versus 10 (1-40) minutes and 10 (1-45) minutes, respectively. Onset of motor block in both territories was also shorter in group MF compared with PB, 6 (2-35) minutes and 5 (2-55) minutes versus 15 (2-60) minutes and 15 (2-60) minutes, respectively (P <.05). There was no difference in duration of sensory and motor blockade, 16 (7-32) hours versus 16 (6-43) hours and 16 (8-32) hours versus 16 (6-25) hours. There was no significant difference between both groups with respect to @entity616 performance. @entity1 discomfort during needle puncture was also similar. CONCLUSIONS: The midfemoral @entity1930 for ankle and foot surgery resulted in a reliable anesthetic, comparable to that of the lateral popliteal approach. This technique is simple, safe, and provides postoperative @entity1337 as effective as that obtained with the lateral approach.
