Bedside Ultrasound on the Effectiveness of Lumbar Puncture in Children.

Condition(s) studied

Investigational drug(s) / intervention(s)

bedside ultrasound examination of the lumbar spinal canal: The ultrasound examination will be performed using a Lumify linear probe (frequency range 4-12 MHz). In the longitudinal projection, the doctor will assess the spinal cord endings by marking them with a sterile marker - a horizontal line on the patient's back. In the same projection, the doctor will designate a safe and optimal place (the greatest width of the dural sac) for performing a lumbar puncture by marking it with a sterile marker. Additionally, in the longitudinal projection, the researcher will measure the depth from the skin surface to the dura mater. Then, in the transverse projection, the doctor will confirm the absence of the spinal cord at the planned puncture site and the optimal amount of cerebrospinal fluid in the selected space. This information will be passed on to the operator, who will ultimately decide on the lumbar puncture site.

Study summary

The aim of the study is to assess the influence of ultrasound examination of the lumbar spinal canal on the effectiveness of lumbar puncture. An open-label, randomized interventional study.
