Summary

The primary objective of this study was to compare ultrasound visibility of the lumbar plexus at the intertransverse space between paramedian transverse scan and shamrock technique. Moreover obtaining a clear image of relevant structures is imperative. Thus, the secondary objective was to assess ultrasound visibility of each relevant structure and overall visibility between these two methods.

Conditions

  • Lumbar Plexus Blockade

Interventions

PROCEDURE

shamrock

This scanning technique is performed in the lateral decubitus position with the side of interest facing upwards. The transducer is placed in the transverse plane on the flank of the patient cranially to the iliac crest. The quadratus lumborum muscle is identified medial to the aponeurosis of the transversus abdominis muscle. With the psoas muscle anterior to the transverse process, the erector spinae muscle posterior to the transverse process, and the quadratus lumborum muscle attached to the apex of the transverse process of L4.

PROCEDURE

paramedian transverse scan

The ultrasound transducer is positioned 4 cm lateral to the midline along the intercristal line and just above the iliac crest. The transducer is also directed slightly medially.
