Some babies experience a lack of oxygen and blood flow around the time of birth. This can lead to a serious condition called hypoxic-ischemic encephalopathy (HIE), which can injure the brain and other organs, including the heart. To reduce brain injury, babies with HIE are treated with therapeutic hypothermia, a standard treatment in which the baby's body temperature is carefully lowered for several days. While cooling helps protect the brain, many babies with HIE still develop heart problems and low blood flow, which may worsen outcomes. Doctors often use medications to support the heart and circulation in these babies, but there is no clear agreement on which medication works best or when it should be started. One commonly used medication is dobutamine, which helps the heart pump more effectively. Dobutamine is already used in newborn intensive care units when babies show signs of heart weakness, but it is usually started only after problems develop. The PROTECT-HIE trial aims to find out whether it is possible and safe to start dobutamine early, before clear signs of heart failure appear, in newborns with HIE who are receiving therapeutic hypothermia. The idea is that early support of the heart may improve blood flow to vital organs, including the brain, and potentially reduce injury. In this study, 40 newborns with HIE will take part at a single neonatal intensive care unit. Babies will be randomly assigned to one of two groups. One group will receive a low, preventative dose of dobutamine within the first four hours after cooling begins. The other group will receive a placebo (an inactive fluid that looks the same). Neither the families nor the medical team assessing outcomes will know which treatment the baby received. The main goal of this study is to determine feasibility-that is, whether starting dobutamine early during cooling can be done reliably and safely in this setting. Researchers will also collect information on important health outcomes, such as signs of brain injury on MRI, seizures, need for additional heart medications, heart function on ultrasound, recovery of blood markers, urine output, length of hospital stay, and survival. Because HIE is an emergency condition and treatment must start very soon after birth, parents will be approached for consent after the baby has been stabilized. This approach is commonly used in neonatal emergency research and has been approved in similar studies. The results of this study will help determine whether a larger trial should be done in the future. Ultimately, this research aims to improve care and outcomes for babies affected by HIE by optimizing support for the heart during a critical period after birth.
