This is because these techniques have been challenging to master and resulted in frequent failure.1,2,3 Dogliotti4 pointed out, “the nerve trunks of the lumbar plexus which run into the inferior extremity are at a great distance from each other, so much so that in order to produce anesthesia, multiple procedures are necessary with separate injections, for each nerve trunk.” Hence, anesthesiologists preferred the more time-efficient, simpler and reliable techniques of spinal or epidural anesthesia. Several variations of the original technique have been proposed, the main differences in these various approaches being in the level of blockade and the distance from the midline for the needle insertion.4,5,6 However, given the deep location of the lumbar plexus, various approaches often represent miniscule technical variations rather than clinically relevant modifications. For instance, Chayen’s approach is thought to result in too high incidence of epidural blockade,7 but another proposed technique also resulted in a 15% incidence of epidural blockade.8 Although ultrasound guidance may allow visualization of the lumbar plexus, the ultrasound guided technique still requires expertise and is technically challenging; refer Chapter 38.9,10,11 Regardless of which technique is followed, certain safety precautions must be used for successful and safe use of this technique.
