NAVADYN11 : Hemodynamic Impact of a New Ventilatory Support Mode With Diaphragmatic Synchronization

September 2, 2013 updated by: Nantes University Hospital

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.

Description

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…)
