Automated Identification of Landmarks During Preprocedure Lumbar Ultrasound for Spinal Anesthesia in Obese Parturients: A Prospective Cohort Study

Abstract

(Eur J Anaesthesiol. 2023;40(9):710–714) Traditional neuraxial procedures, relying on palpation, face a notable 27% failure rate. The integration of preprocedure ultrasonography offers a potential solution, although challenges arise in obese parturients, resulting in a 76% procedural success rate compared to over 90% in nonobese counterparts.
