Summary
Premature babies under 30 weeks gestation are up to a hundred times more likely than full term babies to die or survive with major disability, often from brain damage due to poor blood flow after birth. This randomised study will find out if giving them more placental blood at birth, by means of a delay in clamping the umbilical cord, then milking it, reduces anemia, blood transfusions, brain damage, infection, death and disability. The results may benefit millions of premature babies worldwide.

Summary
Neonatal respiratory distress syndrome (RDS) is the major cause of morbidity and mortality in preterm infants. Many of these infants need ventilatory support to keep them alive. In 1996 and 1997, 10,471 infants in Australia and New Zealand needed ventilatory support for a total of 72,544 days. This treatment is a great physical burden for the infants and an enormous emotional stress for their parents. Each day of treatment costs about A$2000 so their hospital treatment costs about $72 million a ....Neonatal respiratory distress syndrome (RDS) is the major cause of morbidity and mortality in preterm infants. Many of these infants need ventilatory support to keep them alive. In 1996 and 1997, 10,471 infants in Australia and New Zealand needed ventilatory support for a total of 72,544 days. This treatment is a great physical burden for the infants and an enormous emotional stress for their parents. Each day of treatment costs about A$2000 so their hospital treatment costs about $72 million a year. Of infants born less than 29 weeks' gestational age, about 40% of the survivors subsequently developed chronic lung disease (CLD). This condition is defined as prolonged dependence on supplementary oxygen therapy. CLD is associated with further costs and increased lung problems and readmissions to hospital in the first year of life. Thus, CLD is an expensive and time-consuming condition that has a high social cost. This project will determine whether treating these very premature babies from birth simply by applying oxygen under a low continuous positive pressure (CPAP) into their nose rather than the present treatment of placing a tube in the windpipe (known as intubation) and ventilation will reduce the incidence and severity of neonatal respiratory distress syndrome and subsequent chronic lung disease. The project will involve 600 babies from different, high quality neonatal intensive care units. Babies who are born at less than 29 weeks' gestation and who show signs of breathing at birth will be randomly allocated to be treated with either nasal CPAP or intubation and ventilation. This project will determine whether CPAP treatment at birth improves survival and reduces the severity of the RDS and subsequent CLD, or has no long term beneficial effect. If the trial is successful, this will be one of the most useful new treatments in neonatal medicine because it is simple to use, easier for the babies, and cheaper than ventilation.Read moreRead less
Previous research has shown that SIDS victims have a number of subtle abnormalities that set them apart from the normal population. These include the occurrence of upper airway obstruction in sleep, a reduced ability to awaken from sleep and abnormalities of the automatic control of heart rate and blood pressure in sleep. These body functions are controlled by a component of the brain called the autonomic nervous system which controls the heart and other internal functions by means of nerves cal ....Previous research has shown that SIDS victims have a number of subtle abnormalities that set them apart from the normal population. These include the occurrence of upper airway obstruction in sleep, a reduced ability to awaken from sleep and abnormalities of the automatic control of heart rate and blood pressure in sleep. These body functions are controlled by a component of the brain called the autonomic nervous system which controls the heart and other internal functions by means of nerves called the parasymmpathetic and sympathetic systems. The purpose of this project is to undertake studies of the autonomic system in normal infants and in those infants who are considered to be at risk for SIDS. As SIDS occurs almost exclusively in sleep it is important to study the infant?s heart rate and blood pressure responses to various challenges whilst asleep. All infants (both controls and subjects) enrolled in the protocol will therefore undergo overnight sleep studies during which their automatic responses to a variety of stimuli will be measured. Once we have established the normal response to these stimuli we can then compare them to the results of the at risk group. If, as we anticipate, there is a difference between our at risk group and the normal controls in automatic function then we will measure some of the stress hormones in the body which reflect the function of the autonomic nervous system. If there is a difference in the levels of these hormones between the normal and the at risk groups which correlates with the expected subtle abnormalities in function we may be able to devise an accessible and quantifiable measure for those infants at risk of SIDSRead moreRead less
