Some cadaver studies have been performed with injection of dye in the classical TAP. However, it is still not clear whether a single injection of local anesthetic in the classical TAP block position will reach the more cephalad and medial intercostal TAP plexus (Th6-Th9). In this study the investigators use MR scanning and ultrasonography to investigate in what way a known volume of local anesthetic injectate will be distributed in the transverse abdominis plane (TAP) in young healthy male volunteers.
