Lateral approach of transversus abdominis plane (TAP) block. (a) The probe position and needle trajectory. The probe is near or at the midaxillary line between the costal margin and the iliac crest. The needle is inserted in plane. (b) Corresponding ultrasound images. The TAP is between internal oblique and transversus abdominis. The local anesthetic is deposited in this plane to cover the lower TAP plexus. White dashed line: needle trajectory. Light blue area: the deposition site of local anesthetic. TA: transversus abdominis; IO: internal oblique; EO: external oblique.
