What is Shaken Baby Syndrome Infant brain tissue and cerebral blood vessels are more fragile than those of adults, and studies have shown that the younger the infant, the more susceptible he or she is to shock injury. When the baby thrown upward higher, due to the outside of the skull, and the inside of the brain tissue specific gravity is small, in the process of upward and free fall, both can produce speed difference, similar to the aircraft takeoff and landing or ride over the acceleration produced by the car; this speed difference in the force generated by the baby’s hard skull and fragile and delicate brain tissue collision with each other lightly lead to concussion, the heavier caused by cerebral contusion injury In some cases, even the cerebral blood vessels are torn, causing subarachnoid hemorrhage, followed by cerebral edema, intracranial hypertension, coma or even death; or due to extensive damage to the cerebral cortex, resulting in “brain death” and become a vegetable. In addition to high-throw vibration easy to cause brain injury, large-scale shaking can also appear baby shaking syndrome, because the physiological characteristics of the baby’s head is big and small, its head volume and weight accounted for the proportion of the whole body is much larger than that of an adult, coupled with the baby’s neck muscles are weak and tender, and it is difficult to support the large skull, the more large-scale shaking of the baby, the baby’s head with the movement of the swing, the intracranial brain tissue and the harder cranial bone collided with brain injuries. Brain injury. Therefore, the following games and actions should be avoided to prevent the occurrence of shaken baby syndrome, including forcefully patting the back of babies under 3 months; holding the baby to get up, neglecting to support its head and neck; holding or carrying the baby, neglecting to support its head and neck, resulting in severe head shaking; grabbing the baby’s shoulders to swing back and forth; dropping the baby hard to the mattress or sofa and chair, so that it is subjected to the rebound force of the up and down oscillations; shaking the baby’s slap ; baby riding in a car is not fixed in a safety seat; teasing the baby will be thrown upward to play; holding the baby as a swing swing back and forth and suddenly stop; holding the baby spinning; the baby on the shoulders of adults swing; let the baby sit on the adult’s knees or feet, back and forth and around constantly rocking.
