Final answer:
Shaken baby syndrome involves a triad of brain swelling, retinal hemorrhage, and subdural hematoma, caused by the violent shaking or impact on an infant's head and often triggered by a baby's crying.
Step-by-step explanation:
The triad of injuries associated with shaken baby syndrome (SBS) typically includes brain swelling, retinal hemorrhage, and subdural hematoma. This severe form of physical abuse occurs when an infant is forcefully shaken or subjected to an impact on the head, often triggered by a baby's persistent crying and the caregiver's loss of control. It's estimated that each year, 1,400 babies die or suffer serious injury from SBS. Symptoms of this tragic syndrome may include temperature instability, apnea, bradycardia, hypotension, feeding difficulty, irritability, limpness, and in more severe cases, seizures, bulging fontanel, or hemiparesis, which may often be fatal.
