Ultrasound-Assisted Lumbar Puncture in Children

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03099642
Recruitment Status : Completed

Brief Summary:
The aim of this study is to determine if emergency physician performed ultrasound-assisted lumbar puncture improves first-time success rates in a pediatric population. This will be done by comparison with current landmark-based approach to the procedure.

Arm Intervention/treatment
Experimental: Ultrasound assisted lumbar puncture
The intervention of interest will be the ultrasound-assisted lumbar puncture (UALP). To do this, the treating physician will perform a bedside ultrasound of the spine to identify and mark the level of the conus medullaris and preferred puncture site prior to LP
Radiation: ultrasound-assisted lumbar puncture
The ultrasound probe type will be selected by the treating pediatric emergency physician who has been trained according to standards outlined below. They will first identify the conus medullaris and make a horizontal marking with a sterile pen on the patient's back. Using a transverse view, they will then identify the midline of the patient's spine (using adjacent spinous processes) and will make 2 vertical skin markings on either side of the probe. Next, they will orient the probe in a longitudinal view to identify the desired vertebral interspace and will make 2 horizontal skin markings on either side of the probe at this level. Finally the 4 lines will be joined together at an intersection point, which will be the predetermined site for puncture attempt.

No Intervention: Standard lumbar puncture
The control group will have a standard landmark-based lumbar puncture

Primary Outcome Measures :
  1. First-tie success [ Time Frame: 15 minutes ]
    First-time lumbar puncture success rate is defined by the presence of at least 0.5 mL of cerebrospinal fluid with red blood cell count < 1,000/mm3.

Secondary Outcome Measures :
  1. Total lumbar puncture success rate [ Time Frame: 15 minutes ]
    defined by the presence of at least 0.5 mL of cerebrospinal fluid with red blood cell count < 1,000/mm3 in any number of attempt

  2. Change in performer [ Time Frame: 15 minutes ]
    If the lumbar puncture was attempted by a second person following the first attempts

  3. Time of procedure [ Time Frame: 30 minutes ]
    Time to perform the lumbar puncture

  4. Complication [ Time Frame: 30 minutes ]
    Occurence of any complication
