Design outcomes

Primary

Measure	Time frame
success rate in obtaining clear cerebrospinal fluid by ultrasound-assisted lumbar puncture	—

Secondary

Measure	Time frame
traumatic tap rate success rate for clear cerebrospinal fluid on the first attempt Comparison in the following items between the two groups, ultrasound imaging versus palpation method: success rate for clear cerebrospinal fluid, success rate for clear cerebrospinal fluid on the first attempt, traumatic tap rate, elapsed time for ultrasound imaging. Associations among the successful ultrasound-assisted lumbar puncture and the following factors; local anesthesia, early-stylet removal technique, elapsed time for ultrasound-imaging, the number of attempts, age, body weight, consciousness, body movement in the process of lumbar puncture, experience of the operator as a pediatrician, spinal canal depth, and puncture depth deeper than the measured one from skin to anterior spinal canal. Association between depth of spinal canal and child's length or weight, association between the depth of a needle where cerebrospinal fluid is obtained and the measured one, and the predictive formula of depth of spinal canal by using explanation variables such as weight or length.	—
