  Purpose

Aims: There is increasing evidence that volume-targeted ventilation (VTV) holds benefits for preterm infants in comparison to pressure-limited ventilation. This study aims to compare pressure-limited to VTV in preterm infants.

Hypothesis: Volume-targeted will be associated with more rapid achievement of weaning criteria compared to pressure-limited ventilation

Primary outcome: Time taken to achieve pre-specified weaning criteria.

Methods: Ventilated infants less than 34 weeks gestational age at birth were recruited within the first 24 hours of life and randomly allocated to receive either pressure-limited or VTV. Adjustments to ventilator settings were made according to the trial protocol. Infants were deemed to have met failure criteria if they required HFOV, required peak pressures of more than 26 cm of water or developed pulmonary haemorrhage. Analysis will be by intention-to-treat.

Primary Outcome Measures:
  • Time to achieve weaning criteria
    Peak inspiratory pressure (PIP) of 16 cm of water or less AND fraction of inspired oxygen of 0.4 or less for at least 6 hours


Enrollment: 40
Study Start Date: July 2010
Study Completion Date: February 2012
Primary Completion Date: February 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Pressure-limited ventilation Device: Ventilation protocol delivered by the SLE5000 ventilator

In pressure-limited ventilation arm, preferentially wean pressure till weaning criteria achieved, then wean rate.

In volume-targeted ventilation arm, set target volume at 5ml/kg and wean rate. In both arms, aim to keep blood gases within normal limits.
