Summary
The body's own protective mechanism against injury due to reduced blood flow (ischemic preconditioning) has been studied for over 2 decades, yet the clinical benefits have not been realised until recently . We have previously shown that this innate protection can be induced without drugs in children having heart surgery. We will extend these findings to determine the mechanism of protection, develop a method to monitor this in blood cells and see if this is related to post-operative outcomes.
Nasal Highflow For Paediatric Acute Hypoxic Respiratory Failure

Summary
The burden of respiratory disease in children requiring intensive care admission is increasing despite better quality care in hospitals. This study investigates a new method, called nasal high flow, to support the breathing of children, that can be provided in regular children's wards in regional and metropolitan hospitals. The study anticipates to demonstrate that early intervention with nasal high flow reduces the need for intensive care admission.
Surgical Management Of The Pulmonary Circulation In Children

Summary
Congenital disorders of the lung circulation are rare. These children often present during infancy with symptoms of heart failure and require surgery to correct these defects. Without surgery, the prognosis of these conditions are poor. Our understanding of these conditions are limited. The proposed study aims to review all patients who underwent surgical repair of abnormalities of lung arteries and veins at the Royal Children’s Hospital.

Summary
Chronic suppurative (ie infected) lung diseases in children are major causes of poor health and deaths worldwide. Repeated childhood infections contribute to poor lung health in adults. The most common organism causing infection is non-typeable Haemophilus influenzae (NTHi). This study aims to determine whether a vaccine against NTHi can reduce repeated respiratory infections in children. If so, vaccination may lead to substantial improvements in current/ future lung health, and considerable dir ....Chronic suppurative (ie infected) lung diseases in children are major causes of poor health and deaths worldwide.

This study aims to determine whether a vaccine against NTHi can reduce repeated respiratory infections in children.

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. 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 shorte ....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. 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

Summary
Sleep-disordered breathing such as obstructive sleep apnoea, is currently diagnosed if a child stops breathing more than once per hour. For children with asthma or cystic fibrosis, who may not stop breathing during the night, how hard their breathing muscles work can have a significant impact on their health. A non-invasive method of measuring respiratory effort, and incorporating this measurement into how sleep-disordered breathing is diagnosed, can revolutionize how sleep-disordered breathing ....Sleep-disordered breathing such as obstructive sleep apnoea, is currently diagnosed if a child stops breathing more than once per hour.

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. Several new treatments have helped to improve their survival rate, but some have the potential to cause long-term harm to the developing baby's brain or lung, and may cause lifelong problems with thinking, walking, talking, seeing, hearing, growth or breathing.

Several new treatments have helped to improve their survival rate, but some have the potential to cause long-term harm to the developing baby's brain or lung, and may cause lifelong problems with thinking, walking, talking, seeing, hearing, growth or breathing. 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 assessed long term (to 8-9 years of age), as broadly as possible, and in comparison with normal birthweight (NBW, birthweight >2499 g) children. Outcomes will encompass academic progress and behaviour, brain function, general health, growth, and respiratory health. We will compare the outcomes for very tiny-preterm children who were treated with several of these new therapies with those who were not so treated. We will assess whether alternative measures of long term outcome that assess the quality of life are applicable to very tiny-preterm children. If so, these measures could be used much more widely, since they are cheaper and less time-consuming.Read moreRead less
