Research summary
This short pilot study is to assess the tolerance of preterm infants, born below 32 weeks gestation with respiratory distress syndrome, to flow-cycle ventilation, and see if infants require less overall pressure from the ventilator than the usual conventional settings used, with the aim of providing data to construct a larger trial looking at the longer term outcome of these infants using this type of ventilation in the future.
Many preterm infants at these gestations require assistance from a ventilator due to the immaturity of their lungs. The lungs of preterm infants are susceptible to damage, especially if high pressures are needed or prolonged periods of ventilation. There is concern that if the infant's breathing pattern does not synchronise with the ventilator, this causes additional distress, longer duration of ventilation needed and increased risk of complications. Over the past 20 years, a different type of ventilation, known as flow-cycle ventilation, has been trialled, with limited use in preterm infants. This allows the baby to determine the duration of breathing in and out and how many breaths they require per minute. This would help babies to synchronise better with the ventilator, and consequently require less pressure from the ventilator.
This pilot study is being conducted at St. Mary's Hospital, Manchester. All babies born under 32 weeks gestation, with a stable respiratory effort, will be eligible for consideration for the study.
The study will last no longer than 5 hours and involve the babies receiving different pressures from the ventilator in flow-cycle mode for 1-hour epochs. Blood gases after each epoch and continuous ventilator data will be downloaded to assess their tolerance on the different settings, before being returned to the usual conventional settings used on the unit. The babies will have continuous monitoring throughout as per standard neonatal intensive care.
