Brief description Retinopathy of prematurity (ROP) is a serious complication of premature birth, and is a major cause of preventable blindness. Babies who are born before 28 weeks gestation are at greatest risk for developing severe ROP. Oxygen is one of the most common therapies used daily to care for premature babies, but high oxygen levels are one of multiple factors that can disrupt normal eye development and contribute to ROP. The current dilemma is that doctors and nurses do not know what level of oxygenation is both safe and most effective for these babies. Whilst higher oxygen levels may increase ROP and other respiratory problems, it is possible that lower oxygen levels may affect other long-term outcomes. Because there is no definitive evidence regarding appropriate oxygenation, a wide spectrum of opinion and practice currently exist. Australia is conducting The Benefits of Oxygen Saturation Targeting Trial (BOOST II), a research study to solve this dilemma. BOOST II is a randomised, double blind, clinical trial, which will study the effects of using two ranges of oxygen saturation, 85-89% versus a higher range 91-95% for infants born before 28 weeks gestation. Both of these oxygen level ranges are currently used in normal practice. Patient safety will be monitored closely, and each infant will have their development, vision and health assessed by specialists at 18-24 months of age (plus the number of weeks premature), to see whether there is difference in survival free of major disability between the two groups. 1200 Australian infants will participate. This study will answer important questions about the benefits and risks of higher versus lower oxygen levels, and will improve the care of thousands of Australian children and millions more worldwide.
