NCT06062446

Brief Summary

The purpose of this study is to o determine whether the modified LP procedure reduces the incidence of PLPH to 5% or lower, to determine whether the modified LP procedure reduces the frequency of epidural blood patch (EBP) usage to 10% or lower of the PLPH population and to identify factors that may contribute to or reduce incidence of PLPH

Outcome Measures

Primary Outcomes (4)

  • Number of participants with headaches as assessed by a questionnaire

    Participants will answer "Yes" or "No" in response to 1-2 questions: 1) Do you have a headache? 2) If you answered "Yes" to the previous question, does the headache get better when you sit up?

    30-60 minutes after LP

  • Number of participants with headaches as assessed by a questionnaire

    Participants will answer "Yes" or "No" in response to 1-2 questions: 1) Do you have a headache? Or have you had a headache since the lumbar puncture? 2) If you answered "Yes" to the previous question, does the headache get better when you sit up?

    1 day after LP

  • Number of participants with headaches as assessed by a questionnaire

    Participants will answer "Yes" or "No" in response to 1-2 questions: 1) Do you have a headache? Or have you had a headache since the lumbar puncture? 2) If you answered "Yes" to the previous question, does the headache get better when you sit up?

    3 days after LP

  • Number of participants with headaches as assessed by a questionnaire

    Participants will answer "Yes" or "No" in response to 1-2 questions: 1) Do you have a headache? Or have you had a headache since the lumbar puncture? 2) If you answered "Yes" to the previous question, does the headache get better when you sit up?

    5 days after LP

Secondary Outcomes (3)

  • Number of participants that use the epidural blood patch

    1 day after the LP

  • Number of participants that use the epidural blood patch

    3 days after the LP

  • Number of participants that use the epidural blood patch

    5 days after the LP

Study Arms (1)

Modified Lumbar Puncture

EXPERIMENTAL
Procedure: Modified Lumbar Puncture

Interventions

The Investigator will perform the modified LP procedure using the 22 Gg needles Quincke spinal needle (namely, without reinsertion of stylet into the spinal needle after cerebrospinal fluid (CSF) collection before spinal needle removal).

Modified Lumbar Puncture
