NCT03167190

Brief Summary

Although the lumbar puncture is a common procedure and has been performed without ultrasound for decades, other research studies suggest that there may be some benefits to using ultrasound. This study intends to see whether by using ultrasound there is increased success rate, decreased need for additional procedures, and less discomfort during the procedure.

Outcome Measures

Primary Outcomes (1)

  • Mean Procedural Duration

    This is defined by number of minutes from initiating of patient positioning (prior to evaluation of the anatomical landmarks) to first flow of cerebrospinal fluid (CSF).

    Approximately 1 hour

Secondary Outcomes (7)

  • Number of Procedures Considered to be Failures

    Approximately 1 hour

  • Number of Fluoroscopically Guided or CT Guided Lumbar Punctures

    Approximately 7 days

  • Total number of unique skin punctures

    Approximately 1 day

  • Procedurist reported ease of the procedure

    Approximately 1 day

  • Patient reported discomfort

    Approximately 1 day

  • +2 more secondary outcomes

Study Arms (2)

Control

OTHER

Traditional landmark-based lumbar puncture technique by palpation

Procedure: Traditional Landmark-based Lumbar Puncture

Experimental (ultrasound)

EXPERIMENTAL

Use of point-of-care ultrasound to identify bony landmarks.

Procedure: Point-of-care ultrasound

Interventions

A point-of-care ultrasound machine will be utilized to identify and mark midline and the interspinous space based on visualization of spinous processes.

Experimental (ultrasound)

Palpation of anatomical landmarks to identify midline and interspinous space

Control

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients who registered for an emergency or inpatient encounter between 5/22/2017 and 5/08/2018
  • Males or females 18 years of age or older
  • Patients who have been identified as requiring a lumbar puncture for any therapeutic or diagnostic or therapeutic indication, as decided by the neurology staff physicians, residents, or advanced practice providers.

You may not qualify if:

  • Patients who are not capable of providing consent for participation in research and do not have an authorized relative or power of attorney to consent in their stead.
  • Patients who require lumbar puncture in an emergency, time dependent fashion and in whom a possible delay could conceivable have a negative clinical impact.
  • Patients with known abnormal lumbar spinal anatomy or prior extensive surgical fusion such that fluoroscopic or CT guidance is determined to be more clinically appropriate by the treating physicians.
  • BMI greater than 60
  • Absolute contraindication to lumbar puncture such as uncorrected coagulopathy
