 - Technique of ultrasound guided Transversus abdominis plane Block: Patient lie in supine position and high-frequency linear transducer 7-12 MHZ attached to ultrasound machine placed in anterior axillary line between costal margin and iliac crest to visualize the typical triple abdominal layers. A 21 G cannula needle is then moved forward from an anteromedial position in a posterior and lateral direction using an in-plane technique with the entry point in the skin being separated from the probe in order to improve needle visibility in the long axis. The needle tip is inserted between transversus abdominis muscle and internal oblique muscle then local anesthetic is injected to produce separation between the two muscle.
