Abstract
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.
