Adductor canal block: Effect of volume of injectate on sciatic extension

Context: Spread of local anesthetic within adductor canal to peroneal and tibial nerves is described in literature. This spread could be volume-dependent. Aims: In this study, we compared the diffusion of two volumes of 0.375% ropivacaine to popliteal fossa. Settings and Design: This was a prospecti...

Description
Summary:Context: Spread of local anesthetic within adductor canal to peroneal and tibial nerves is described in literature. This spread could be volume-dependent. Aims: In this study, we compared the diffusion of two volumes of 0.375% ropivacaine to popliteal fossa. Settings and Design: This was a prospective, randomized controlled, single-blind study conducted in Kassab Orthopaedic Institute of Tunis for 1 year (2018). Materials and Methods: A total of 42 patients, American Society of Anesthesiologists I/II scheduled for knee arthroscopy under spinal anesthesia scheduled to receive adductor canal block, were randomized into two groups: group N received 20 mL of ropivacaine 0.375% and group H received 40 mL. We evaluated sensory motor blocks of both peroneal and tibial nerves at 30 and 60 min. Statistical Analysis Used: Chi-square or Fisher's exact test was used to compare the number and percentage.P
