  Purpose

The main objective of this study is to evaluate the inter-rater reproducibility of diaphragmatic excursion measures via time-motion-mode ultrasound (evaluation performed on the first measure) in patients experiencing acute respiratory distress emergencies.


Condition Intervention
Respiratory Distress Syndrome, Adult
 Procedure: Diaphragm excursion measures 1
Procedure: Diaphragm excursion measures 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: Reproductibility of Time-motion-mode Ultrasound Diaphragm Measures in Patients With Acute Respiratory Distress in the Emergency Room

Further study details as provided by Centre Hospitalier Universitaire de Nīmes:

Primary Outcome Measures:
  • Diaphragmatic excursion, first measure by investigator 1 [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]
    in centimeters

  • Diaphragmatic excursion, first measure by investigator 2 [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]
    in centimeters


Secondary Outcome Measures:
  • Time necessary to measure diaphragm movement amplitude (minutes) [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]
  • Feasibility (yes/no) [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]
    We were able to perform the required measurements (yes/no)

  • Diaphragmatic excursion, second measure by investigator 1 [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]
    (centimeters)

  • Diaphragmatic excursion, second measure by investigator 2 [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]
    (centimeters)


Other Outcome Measures:
  • Age [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]
  • Sexe [ Time Frame: Baseline (day 0) ] [ Designated as safety issue: No ]

Estimated Enrollment: 25
Study Start Date: September 2013
Estimated Study Completion Date: March 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Study population

The study population consists of patients treated for acute respiratory distress in the emergency department at the Nîmes University Hospital. See inclusion and exclusion criteria.

Interventions: Diaphragm excursion measures 1, Diaphragm excursion measures 2

 Procedure: Diaphragm excursion measures 1
A first diaphragm ultrasound study will be carried out by investigator 1. A Vivid S6 GE Ultrasound will be used, with a phased array cardiac probe.
Procedure: Diaphragm excursion measures 2
A second diaphragm ultrasound study will be carried out immediately after Ultrasound 1, and by investigator 2. The results are blinded between investigators. A Vivid S6 GE Ultrasound will be used, with a phased array cardiac probe.

Detailed Description:

The secondary objectives of this study are:

  • To assess the feasibility of measuring the diaphragmatic excursion in the context of emergency management (ratio of measured patients / included patients).
  • To evaluate the time required for the measurement.
  • To assess the intra-rater reproducibility of measurements of diaphragmatic excursion (comparison of first and second measures).
  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • The patient must have given his/her informed and signed consent
  • The patient must be insured or beneficiary of a health insurance plan
  • The patient has acute respiratory distress defined by a respiratory rate > 25, and / or signs of struggle and hypoxia, oxygen saturation (SpO2) <90% and / or pH <7.35 and carbon dioxide partial pressure (pCO2) > 6 kPa (45 mm Hg)
  • The patient breathes spontaneously (no respirator)

Exclusion Criteria:

  • The patient is participating in another study
  • The patient is in an exclusion period determined by a previous study
  • The patient is under judicial protection, under tutorship or curatorship
  • The patient or his/her representative refuses to sign the consent
  • It is impossible to correctly inform the patient, or to correctly inform his/her representative
  • The patient is pregnant, parturient, or breastfeeding
  • The patient has a neurological or neuromuscular disease that modifies diaphragm function/movement; this does not include cases of decompensation (polyradiculoneuropathy, Lou Gehrig's disease, Myasthenia ...).
  • Patient admitted with respiratory support treatment in progress
  • Patient admitted with respiratory failure requiring immediate implementation of mechanical ventilation, thus preventing ultrasound measurements
