Measure
US-Assisted Site Marking for LP
Mindray M7 Ultrasound marking Bedside Ultrasound-Assisted Site Marking: Patient will receive a bedside ultrasound-assisted site marking of the most appropriate site for lumbar puncture prior to the clinician completing the spinal tap using Mindray M7 Ultrasound. Mindray M7 Ultrasound: Patient will receive a bedside ultrasound exam of the most appropriate site for lumbar puncture prior to the clinician completing the spinal tap
Routine Lumbar Puncture
These patients will receive no ultrasound-assisted site marking prior to lumbar puncture; The patients will simply have a "standard-of-care" spinal tap performed by the clinician Routine lumbar puncture: Lumbar puncture will be performed per routine standard of care

Percentage of Successful First Attempt Lumbar Punctures in the Ultrasound-assisted Group as Compared to the Non-ultrasound Assisted Group
58 percent success
Interval 50.0 to 70.0
31 percent success
Interval 19.0 to 39.0

SECONDARY outcome

Timeframe: 30 minutes

Percentage of Overall Success of Lumbar Punctures in the Ultrasound-assisted Group Versus the Non-ultrasound-assisted Group
75 percentage success
Interval 68.0 to 82.0
44 percentage success
Interval 38.0 to 52.0

SECONDARY outcome

Timeframe: Participants will be followed for the duration of the hospital stay, an expected average of 2 days

If a lumbar puncture is not successful, this may lead to a longer hospitalization than necessary until a lumbar puncture can be completed (with interventional radiology or other resources). According to our hypothesis, we believe that ultrasound assistance will increase the proportion of successful lumbar punctures, and therefore, decrease the length of unnecessary hospitalization.

SECONDARY outcome

Timeframe: Participants will be followed until discontinuation of antibiotics, an expected average of 2 days

If a lumbar puncture is not successful, this may lead to unnecessary (prophylactic) antibiotic use until a lumbar puncture can be completed (with interventional radiology or other resources) to rule out meningitis. According to our hypothesis, we believe that ultrasound assistance will increase the proportion of successful lumbar punctures, and therefore, decrease the length of unnecessary antibiotics.
