Summary
In the first few days after birth, some premature babies develop low blood pressure. It is thought that this meant that the amount of blood and oxygen going to the brain would also fall. If blood pressure became very low, this could injure the brain. Drugs are used to prevent low blood pressure, but their effect on blood flow and oxygen in the brain is uncertain.

It is thought that this meant that the amount of blood and oxygen going to the brain would also fall. If blood pressure became very low, this could injure the brain. Drugs are used to prevent low blood pressure, but their effect on blood flow and oxygen in the brain is uncertain. This study aims to develop simple cotside monitoring procedures that allow neonatologists to monitor oxygen supply and blood flow in the brain in tiny babies who weigh less than 1000gm, and what happens within the brain when drugs are given to raise blood pressure. We will employ a new instrument that generates low intensity near infrared light which passes safely into the brain and is absorbed according to the amount of oxygen present in very small blood vessels. As the methodology is new, we intend to first validate the measurement in immature lambs. The instrument will then be applied in studies of babies undergoing intensive care and at risk for low pressure and brain injury, as many as 5000 babies each year in Australia.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”.

Summary
Problems around birth are common and can have long-term implications, including into adulthood. Our goal is to improve health outcomes for all newborn babies and their families by determining factors that enhance outcome and assessing the benefits and consequences of new treatments for mothers and babies. We are world leaders in this field and are dedicated to training the next generation of health professionals in the care of newborn babies, in Australia and the rest of the world.

Summary
With improving technologies and medications the numbers of very premature babies surviving to leave hospital has increased over the last two decades. However these babies are at increased risk of having brain damage in the form of mental retardation and cerebral palsy. These problems impose a major burden on the individuals, their families and society at large. This study attempts to identify whether or not a commonly used drug is safe in these babies or whether it contributes to brain damage in ....With improving technologies and medications the numbers of very premature babies surviving to leave hospital has increased over the last two decades. However these babies are at increased risk of having brain damage in the form of mental retardation and cerebral palsy. These problems impose a major burden on the individuals, their families and society at large. This study attempts to identify whether or not a commonly used drug is safe in these babies or whether it contributes to brain damage in some cases. Many premature babies have difficulty breathing by themselves because their brain does not send regular messages to their lungs telling them to expand. A class of drugs which includes caffeine has been shown to stimulate breathing in babies and has been thought to reduce the amount of support these babies require from a ventilator in the first weeks of life. The safety of these drugs has not been adequately demonstrated in premature babies and there is some evidence from animal studies that they may disrupt the developing brain. Results in human babies are inconclusive and concerns remain regarding the long term effects of caffeine. The question of whether caffeine usage increases the risk of mental retardation or cerebral palsy is a very important one given the almost universal usage of this or similar drugs in premature babies. We will find out whether babies given caffeine as newborns perform as well at 18 months of age as babies not given the drug.Read moreRead less
Right From The Start: Improving Respiratory Support For Preterm Infants From Their First Breath To Independent Breathing

Summary
My research program with the world leading research team at the Royal Women’s Hospital, Melbourne aims to improve the journey of preterm babies from birth, through the neonatal nursery, to a healthy start at home. Too many preterm babies die or have long term health problems. I will study gentler methods to support breathing from birth, investigate better ways of supporting them until they can breathe independently, and assess how to support more babies to stay in their birth hospitals.
Postnatal Dexamethasone In Tiny Babies: Does It Do More Good Than Harm?

Summary
The survival rate for tiny or very premature babies has improved dramatically in recent times, from below 10% in the 1960s to greater than 70% in the 1990s. However, some of these babies require prolonged periods of help with breathing and oxygen treatment to survive, and many develop a form of chronic lung disease in the newborn period.

However, some of these babies require prolonged periods of help with breathing and oxygen treatment to survive, and many develop a form of chronic lung disease in the newborn period. A powerful group of drugs, known as corticosteroids, have been used to treat or prevent this chronic lung disease in newborn babies, with some success in shortening the time that the babies need help with breathing. However, corticosteroids have the potential to cause long-term harm to the developing baby's brain, and may cause lifelong problems with thinking, walking, talking, seeing or hearing. We want to test in a clinical trial if corticosteroids, specifically dexamethasone, can reduce the need for help with breathing and the rate of chronic lung disease without causing long-term problems to the developing baby's brain. Babies who are very tiny (born weighing less than 1000 g), or born very early (born before 28 weeks of pregnancy, or more than 12 weeks premature) will be eligible for this study if they still need help with their breathing after one week of age from a machine called a respirator, and their doctor considers that corticosteroids might be helpful to the baby's breathing. Some babies will receive dexamethasone and other babies will be treated with a harmless placebo - chance will decide which treatment the baby receives. All other aspects of the babies' care will continue as normally. Children who survive to 2 years of age will be assessed fully to determine if they have any problems with their health, including problems with their thinking, walking, talking, seeing or hearing. We will determine if dexamethasone is helpful or not for very tiny or very premature babies who have breathing problems after the first week of life. We will also measure the economic impact of dexamethasone treatment in these babies.Read moreRead less
