Summary
Meconium aspiration syndrome (MAS) is a serious respiratory disease of full term infants, which can lead to very severe respiratory failure. It is caused by the inhalation of meconium, the secretion of the fetal intestine, into the lung at or prior to delivery. As a result, the airways and air sacs within the lung are damaged, leading to difficulty with breathing and poor oxygen levels. About one-third of all infants with MAS require mechanical ventilation in the first days of life, and are ofte ....Meconium aspiration syndrome (MAS) is a serious respiratory disease of full term infants, which can lead to very severe respiratory failure. It is caused by the inhalation of meconium, the secretion of the fetal intestine, into the lung at or prior to delivery. As a result, the airways and air sacs within the lung are damaged, leading to difficulty with breathing and poor oxygen levels. About one-third of all infants with MAS require mechanical ventilation in the first days of life, and are often extremely difficult to manage. At present, the main treatments given to a ventilated infant with severe MAS are supportive, rather than curative. Lung cleansing procedures are not part of routine care in this condition, even though removal of meconium from the lung may reduce the amount of damage that occurs. This project is a randomised controlled trial of a lung cleansing procedure called lung lavage in ventilated infants with severe MAS. During the lung lavage, a quantity of cleansing fluid containing a natural substance called surfactant is introduced into the lung, and then removed by suctioning. This procedure cleanses the lung of some of the meconium, and in preliminary testing, appears to be safe and well-tolerated even in the sickest infants. In the proposed trial, we will randomly allocate ventilated infants with severe MAS to receive either a lung lavage procedure, or routine care. This will take place within 24 hours of birth. We are looking to see whether the lavage procedure shortens the duration of ventilation, oxygen therapy or hospitalisation. Because there are only a small number of ventilated infants with MAS at any one centre per year, we will involve as many Australian neonatal intensive care units as we can in the study. We aim to enrol 66 infants in the trial, of whom half will receive lavage therapy.Read moreRead less
Improving Neonatal Transition For Compromised Infants And Minimising Lung Injury

Summary
The projects in this proposal are designed to improve the health of newly born infants before they are born (fetal lactate blood test to assist in decision making), at birth (randomized clinical trials to provide evidence for future resuscitation guidelines) and in the first few hours following preterm birth by studying alternative methods of providing existing therapies for neonatal respiratory distress syndrome. These studies may prevent harm and allow a “Healthy start to life”.
Towards Improved Respiratory Outcomes In Preterm Infants Through Rapid And Effective Aerosalisation Of Medication To The Lung

Summary
Babies born premature are greatest at risk from increasingly common respiratory illnesses. It is possible that delivering a medication by aerosol will be the most effective method of treatment. For premature babies that need breathing support, inhaled medication could improve care. For highly infectious respiratory illnesses such as RSV, with no vaccines available, we need to protect babies very early in life. I will use an established lamb model to test fast medication delivery to the lungs.
Role Of Viruses In The Development Of Lung Disease In Cystic Fibrosis

Summary
This study will investigate how lung disease starts in babies with cystic fibrosis and the role of viral infections in this process. The new knowledge gained will help us move towards treatments that prevent or delay the start of lung disease, something not currently possible. We believe this new treatment paradigm will lead to improved quality and extent of life of those with cystic fibrosis.
Imaging Lung Aeration And Lung Motion Following Very Premature Birth

Summary
Using a synchrotron as an X-ray source, we will image the lungs as they aerate at birth and optimise ventilation strategies that improve lung aeration while minimising the risk of ventilation-induced lung injury.

In this study we will assess how early lung function evolves in relation to potential insults such as lower respiratory tract infections and allergic inflammation. These are the mechanisms by which asthma is thought to develop. We will use exciting new lung function tests to evaluate lung function abnormalities associated with peripheral dysfunction characteristic of chronic airway disease such as asthma.Read moreRead less
Long Term Outcomes Of Infant Lung Function In Cystic Fibrosis

Summary
We have shown that babies with cystic fibrosis (CF) who are apparently well can still have lung problems. As lung disease is the major cause of death in CF we need ways to monitor the condition in babies, identify those at greatest risk of lung changes and predict which children should receive newer treatments. We have developed a unique program for the measurement of lung function in babies. We now aim to find out the long term consequences of lung function changes detected in infants with CF.
Clinical Trial Of Minimally-invasive Surfactant Therapy

Funding Amount
$1,172,978.00
Summary
This proposal is for funding of a clinical trial investigating a new and less-invasive technique of giving surfactant to improve lung function in preterm babies born between 25 and 28 weeks gestation. The trial will examine whether giving surfactant using the less invasive method results in better outcomes, including a reduction in time on respiratory support, and higher survival without chronic oxygen dependency.

Summary
Bronchopulmonary dysplasia (BPD) remains the most significant chronic lung complication of premature birth. While some information on the long term respiratory outcomes in BPD exist there are no comprehensive studies linking lung structure, function and respiratory symptoms and relating these changes to neonatal history. Studies of this kind are essential to ensure future healthcare for these children can be planned accordingly.

A/Prof Graham Hall is senior researcher at the Telethon Institute for Child Health Research in Perth, Western Australia and is internationally recognised for his research in the area of respiratory physiology in infants and young children. His research focuses on understanding the impact of respiratory diseases, such as asthma and cystic fibrosis, as well as pre-term birth and air pollution on lung function not only in early life but as the lung grows and develops.
