  Purpose

Despite spectacular advances since the 90s mechanical ventilation used in intensive care units are amply associated with cardio-respiratory complications: nosocomial pneumonia, lung parenchyma lesions induced by ventilation, hemodynamic instability and ultimately to a significant morbidity and mortality.

NAVA (Neurally Adjusted Assist Ventilation) ventilatory support, provides synchronous support, proportionate to patient's respiratory efforts. More "physiological", this mode would decline its efficacy on patient hemodynamic response. However, to date, no study has focused on hemodynamic impact of NAVA. This is precisely the purpose of NAVADYN11 study, which aims to assess NAVA efficacy on cardiac index in pediatric intensive care unit.

Further study details as provided by Nantes University Hospital:

Primary Outcome Measures:
  • Assess the impact of NAVA ventilation on hemodynamic parameters
    Assess the impact of NAVA ventilation on hemodynamic parameters in children hospitalized in a Paediatric Intensive Care Unit. Endpoint evaluation consists in a non-invasive measurement of cardiac index by esophageal doppler.


Secondary Outcome Measures:
  • Omega score
    SaO2/SaO2-SvO2

  • Heart rate
  • Blood pressure
  • NIRS
  • Blood gas
  • Lactate
  • BNP
  • Perfusion score
  • Right cardiac work index
    if available


Enrollment: 9
Study Start Date: November 2011
Intervention Details:
    Other: collection of clinical and biological parameters
    Investigation focal lies in hemodynamic monitoring during the last 10 minutes (Cardiac Index Assessment and clinico-biological parameters as: ventilatory and respiratory parameters, NIRS, GDS, Omega Score, heart rate, blood pressure, lactate, BNP, perfusion coefficient…)
    Other: assign optimal ventilatory mode
    End of study: At the end of the second session, clinician will assign optimal ventilatory mode regarding patient clinical response.
  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion criteria:

  • Servo-i with NAVA available at patient admission
  • Sedation protocol compatible with NAVA functioning
  • Parental consent

Non inclusion criteria:

  • Digestive pathology incompatible with gastric tube.
  • Deep sedation required defined by score ComfortB <11 (cranial traumatism…)
  • Brain damage incompatible with spontaneous ventilation
