Ultrasound-Guided Regional Anesthesia: In Plane-Needle Approach
The in plane or long axis needle approach is the technique used to allow visualization of the needle shaft and tip when performing ultrasound-guided regional anesthesia procedures.
The transducer is positioned over the selected nerve(s). The needle is placed at the center of the transducer in-line with the ultrasound beam and the trajectory of the nerve bundle.
The transducer is held stationary with the non-dominant hand while advancing the needle using the dominant hand.
The needle shaft and tip are seen as a bright echogenic line. The nerves are indicated by the yellow arrows.
