Resumen :	Background: This systematic review examines the evidence for preprocedural neuraxial ultrasound as an adjunct to lumbar spinal and epidural anesthesia in adults. Methods: We searched MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases from inception to June 30, 2014, for randomized controlled trials (RCTs) and cohort studies that reported data answering one or more of the following 3 questions: (1) Does ultrasound accurately identify a given lumbar intervertebral space? (2) Does ultrasound accurately predict the needle insertion depth required to reach the epidural or intrathecal space? (3) Does ultrasound improve the efficacy and safety of spinal or lumbar epidural anesthesia? Results: Thirty-one clinical trials and 1 meta-analysis were included in this review. Data from 8 studies indicate that neuraxial ultrasound can identify a given lumbar intervertebral space more accurately than by landmark palpation alone. Thirteen studies reported an excellent correlation between ultrasound-measured depth and needle insertion depth to the epidural or intrathecal space. The mean difference between the 2 measurements was within 3 mm in most studies. Thirteen RCTs, 5 cohort studies, and 1 metaanalysis reported data on efficacy and safety outcomes. Results consistently showed that ultrasound resulted in increased success and ease of performance. Ultrasound seemed to reduce the risk of traumatic procedures but there was otherwise insufficient evidence to conclude if it significantly improves safety. Conclusions: There is significant evidence supporting the role of neuraxial ultrasound in improving the precision and efficacy of neuraxial anesthetic techniques. What's New: We know that neuraxial ultrasound is a useful complement to clinical examination when performing lumbar central neuraxial blocks. It provides anatomical information including the depthof the epidural space, the identity of a given intervertebral level, and the location of the midline and interspinous/interlaminar spaces. This information can be used to successfully guide subsequent needle insertion. Since 2010, new data from RCTs and 1 meta-analysis suggest that neuraxial ultrasound increases the success and reduces the technical difficulty of lumbar central neuraxial blocks. Findings from the meta-analysis suggest that neuraxial ultrasound reduces the risk of traumatic procedures, and thus may possibly contribute to the safety of lumbarcentral neuraxial blocks.
