Ventilator Pressure for Premature Birth
(VPOCH Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines how changing ventilator pressure affects very premature babies with breathing problems. Researchers aim to determine if adjusting the pressure can enhance heart function and oxygen levels. Babies will experience different pressure settings: a decrease in positive end-expiratory pressure (PEEP) followed by an increase, or vice versa, to identify the optimal setting for their heart and lungs using special imaging tools. This trial targets preterm infants over a week old, born before 34 weeks, who still require ventilator support. As an unphased trial, it seeks to explore innovative methods to improve breathing support for premature infants, offering a chance to contribute to vital research.
Will I have to stop taking my current medications?
The trial information does not specify whether participants must stop taking their current medications. It is best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this protocol is safe for preterm infants?
Research has shown that adjusting positive end-expiratory pressure (PEEP) levels in ventilated preterm infants is generally safe. Studies have found that a short-term increase in PEEP does not significantly alter blood flow in the body. However, about 36% of infants experienced some important clinical changes.
One study discovered that increasing PEEP at birth and then lowering it later effectively opens the baby's lungs. This method is commonly used to assist breathing in preterm infants. Experts recommend a PEEP level of at least 5-6 cm H2O to support these infants' breathing, as their lungs require extra help.
Overall, using PEEP is a standard part of care for preterm infants, indicating it is well-tolerated. While some infants may experience important changes, this approach is widely used and considered safe for helping preterm babies breathe early on.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores how different sequences of adjusting PEEP (positive end-expiratory pressure) levels might improve outcomes for premature infants on ventilators. Unlike standard ventilator settings that typically maintain a stable PEEP, this trial investigates the effects of changing PEEP settings either by decreasing first and then increasing, or vice versa. The unique approach could reveal insights into optimizing respiratory support and cardiac function in these vulnerable infants, potentially leading to more personalized and effective care strategies.
What evidence suggests that this trial's treatments could be effective for improving cardiac output and oxygenation in preterm infants?
This trial will compare two methods of adjusting positive end-expiratory pressure (PEEP) to help premature babies breathe better. In one treatment arm, infants will have their PEEP decreased and then increased, potentially improving oxygen levels by keeping their lungs open and easing breathing. In the other treatment arm, infants will start with a high PEEP that is then lowered, which can increase lung size and improve lung function, allowing more air to enter when the lungs are hard to open. Both methods aim to provide optimal breathing support for these tiny newborns.26789

Are You a Good Fit for This Trial?
This trial is for preterm infants born before 34 weeks' gestation, currently on mechanical ventilation or high-frequency jet ventilation (HFJV), over 7 days old but less than a month, and with consent from their legal guardian. Infants must be recovering from respiratory distress syndrome (RDS).Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Baseline Assessment
Baseline assessment of cardiac hemodynamics and respiratory status at the current set PEEP level
Treatment
Infants undergo a 4-hour crossover period of increasing and decreasing PEEP with echocardiography and EIT measurements
Follow-up
Participants are monitored for safety and effectiveness after treatment
What Are the Treatments Tested in This Trial?
Interventions
- Decrease in the PEEP followed by increase in the PEEP
- Increase in the PEEP followed by decrease in the PEEP
Trial Overview
The study tests how changing the positive end-expiratory pressure (PEEP) affects lung compliance, oxygen levels, and heart function in these infants. It uses echocardiography and electrical impedance tomography to measure outcomes after alternating PEEP levels during a crossover period.

Experimental Treatment
Active Control
Infants will be randomized to the order of changes in PEEP levels during mechanical ventilation - increase followed by decrease in PEEP. Baseline parameters looking into cardiac hemodynamics as well as compliance and respiratory mechanics will be assessed using EIT
