NCT03192423

Brief Summary

This study explores lumbar puncture operators stress associated with their performance of the procedure, across three experience levels: Experts, Intermediates, and Novices. The study will investigate the association of this potential stress to patient experienced stress and patient related outcomes of the lumbar puncture procedure.

Outcome Measures

Primary Outcomes (11)

  • Cognitive Appraisal

    Cognitive Appraisal explores the individuals perception of resources and demands for the performance (scores range from 1/6 to 6)

    Five minutes before performance

  • State Trait Anxiety Inventory - Short (before performance)

    A questionaire exploring the stress related anxiety

    Five minutes before performance

  • State Trait Anxiety Inventory - Short (during performance)

    A questionaire exploring the stress related anxiety

    Just before needle insertion

  • Heart Rate Variability before performance (Heart rate)

    Heart Rate Variability: Heart rate (bp/min)

    A recording of 5 minutes obtained five minutes before performance.

  • Heart Rate Variability before performance (Spectrum analysis)

    Heart Rate Variability: Total power (Sum of Low Frequency, Very Low frequency, High Frequency) (ms)

    A recording of 5 minutes obtained five minutes before performance.

  • Heart Rate Variability before performance (Spectrum analysis)

    Heart Rate Variability: LF/HF - ratio

    A recording of 5 minutes obtained five minutes before performance.

  • Heart Rate Variability before performance (Timedomain analysis)

    Heart Rate Variability before performance Timedomain analysis: RMSDD (ms), pNN50 (%)

    A recording of 5 minutes obtained five minutes before performance.

  • Heart Rate Variability during performance (Heart rate)

    Heart Rate Variability: Heart rate (bp/min)

    A recording of 5 minutes obtained five minutes before obtaining liquor or abandoning the procedure.

  • Heart Rate Variability during performance (Spectrum analysis)

    Heart Rate Variability: Total Power (Sum of Low Frequency, Very Low frequency, High Frequency) (ms)

    A recording of 5 minutes obtained five minutes before obtaining liquor or abandoning the procedure.

  • Heart Rate Variability during performance (Spectrum analysis)

    Heart Rate Variability: LF/HF - ratio

    A recording of 5 minutes obtained five minutes before obtaining liquor or abandoning the procedure.

  • Heart Rate Variability during performance (Timedomain analysis)

    Rate Variability before performance Timedomain analysis: RMSDD (ms), pNN50 (%)

    A recording of 5 minutes obtained five minutes before obtaining liquor or abandoning the procedure.

Secondary Outcomes (7)

  • Patients State Trait Anxiety Inventory - Short

    : Five minutes before performance; Just Before Needle insertion; Five minutes after termination of the procedure

  • Procedure outcomes

    Registered during procedure operation

  • Procedure outcomes

    Registered during procedure operation

  • Duration of time to needle insertion

    Obtained during procedure, Time from needle penetration of the skin to obtaining liquor (mm:ss)

  • Confidence in operator

    Assessed five minutes after termination of the procedure

  • +2 more secondary outcomes
