NCT00603174

Brief Summary

The present protocol will demonstrate the feasibility and efficacy of a newly developed mode of mechanical ventilation, Neurally Adjusted Ventilatory Assist, commonly known as NAVA. During NAVA, the timing and magnitude of pressure delivered are controlled by the infants' diaphragm electrical activity (EAdi), a validated measurement of neural respiratory drive. Recent clinical trials in adults and term infants have shown that NAVA is more synchronous than conventional pressure support ventilation, and that NAVA delivers lower mean airway pressures to achieve the same ventilation and respiratory muscle unloading. NAVA has recently been approved for use in infants by Health Canada and the FDA in the United States, and is commercially available on the Servoi ventilator (Maquet Critical Care, Solna, Sweden). The present protocol is designed as a "case study" where the researchers responsible would like to evaluate the feasibility and efficacy of ventilating an infant on NAVA with the Servoi for 12 hours, and to compare it to conventional ventilation.

Study Arms (1)

A

EXPERIMENTAL

Intubated and mechanically ventilated infants with respiratory failure (age \< 1 year old). see inclusion-exclusion criteria.

Device: neurally adjusted ventilatory assist (NAVA)

Interventions

Following the titration of PEEP and the NAVA level, the infant will be ventilated on NAVA with the titrated levels. The following will be monitored and recorded for 20 min at 1 hour intervals: Phasic EAdi, tonic EAdi, tidal volume, ventilator-delivered pressure, respiratory rate, oxygen saturation, end tidal PCO2, and heart rate.

Eligibility Criteria

AgeUp to 12 Months
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Intubated and mechanically ventilated infant with respiratory failure \< 1 year old)
  • Breathing spontaneously, as defined by the ability to trigger the ventilator
  • The infant should be breathing on conventional ventilation (SIMV, assist control, or pressure support) with the following ventilator parameters: pressure plateau \< 22 cm H2O (above PEEP) and PEEP ≤ 6 cm H2O.

You may not qualify if:

  • Pneumothorax
  • Degenerative neuromuscular disease
  • Bleeding disorders
  • Cardiovascular instability defined by vasopressors infusion (dopamine ≥ 5µg/kg/min, epinephrine, norepinephrine, dobutamine, vasopressin)
  • Cyanotic congenital cardiovascular disease
  • Phrenic nerve damage/diaphragm paralysis
  • Esophageal perforation
  • Use of high frequency oscillatory or jet ventilation
  • Contraindication to changing naso gastric tube
  • Infant is deemed "too unstable" by the attending physician
