Pediatric emergency medicine point-of-care ultrasound: summary of the evidence
AIM To assess the utility of bedside ultrasound performed by an emergency physician in adults undergoing diagnostic lumbar puncture. METHOD Ultrasound was used as the primary means of determining the site of skin puncture, angle of needle advancement and depth needed to access the subarachnoid space. RESULTS Cerebrospinal fluid was obtained from 36 of 39 patients (92.3%) in the first interspinous space attempted. CONCLUSIONS The ultrasonographically measured depth of the dura mater correlates strongly with the final needle depth.
