[Shaken baby syndrome].
Shaken baby syndrome (SBS) describes the coincidence of subdural hematoma, retinal bleeding and, disadvantageous for the prognosis, diffuse brain damage caused by powerful shaking of the infant. The clinical symptoms include irritability, difficulty with drinking, somnolence, apathy, cerebral cramp attacks, apnoea, temperature regulation disorders and vomiting due to cranial pressure. Milder symptoms of SBS are often not diagnosed and the number of unregistered cases is probably much greater. The diagnosis of SBS is made through the typical symptom constellation, but the lack of retinal bleeding does not exclude the diagnosis. Normally the infants are held by the thorax or upper arms and shaken in a sagittal direction during which the head falls backwards and forwards and is stopped abruptly at each extreme position. The injurious mechanism is considered to be caused by rotational forces which force tissue layers in the brain against each other and also lead to rupture of bridging veins between the skull and the brain. The prognosis is poor and approximately 25% of infants die of SBS within days or weeks. Approximately 75% of survivors suffer from long term damage with physical handicaps, limitations in hearing, visual disturbances up to blindness and mental disorders or combinations of these conditions. Prevention is therefore the most important aspect.
