Identification of a particular vertebral level by clinical landmark palpation is inaccurate. This study uses ultrasound imaging to assess the vertebral level at which the palpated intercristal line occurs in subjects clinically positioned to receive a neuraxial technique. ⋯ According to ultrasound, the palpated intercristal line falls at the L3-4 interspace, or below, in the majority of subjects positioned for neuraxial block in the sitting position. A palpated intercristal line at L2-3 was more likely in tall and male individuals.

The Guidelines to the Practice of Anesthesia Revised Edition 2010 (the guidelines) were prepared by the Canadian Anesthesiologists' Society (CAS), which reserves the right to determine their publication and distribution. Because the guidelines are subject to revision, updated versions are published annually. Whereas previous versions of the guidelines appeared as special supplements to the Canadian Journal of Anesthesia (the Journal), this edition of the guidelines is published within the Journal. ⋯ Although the CAS encourages Canadian anesthesiologists to adhere to its practice guidelines to ensure high-quality patient care, the society cannot guarantee any specific patient outcome. Each anesthesiologist should exercise his or her own professional judgement in determining the proper course of action for any patient's circumstances. The CAS assumes no responsibility or liability for any error or omission arising from the use of any information contained in its Guidelines to the Practice of Anesthesia.
