Shaken Baby Syndrome 

Definition

Shaken baby syndrome (SBS) is a collective term for the internal head injuries a baby or young child sustains from being violently shaken.

Description

Shaken baby syndrome was first described in medical literature in 1972. Physicians earlier labeled these injuries as accidental, but as more about child abuse became known, more cases of this syndrome were properly diagnosed.

Every year, nearly 50,000 children in the United States are forcefully shaken by their caretakers. More than 60% of these children are boys. The victims are on average six to eight months old, but may be as old as five years or as young as a few days.

Men are more likely than women to shake a child; typically, these men are in their early 20s and are the baby's father or the mother's boyfriend. Women who inflict SBS are more likely to be babysitters or child care providers than the baby's mother. The shaking may occur as a response of frustration to the baby's inconsolable crying or as an action of routine abuse.

Causes and symptoms

Infants and small children are especially vulnerable to SBS because their neck muscles are still too weak to adequately support their disproportionately large heads, and their young brain tissue and blood vessels are extremely fragile. When an infant is vigorously shaken by the arms, legs, shoulders, or chest, the whiplash motion repeatedly jars the baby's brain with tremendous force, causing internal damage and bleeding. While there may be no obvious external signs of injury following shaking, the child may suffer internally from brain bleeding and bruising (called subdural hemorrhage and hematoma); brain swelling and damage (called cerebral edema); mental retardation; blindness, hearing loss, paralysis, speech impairment, and learning disabilities; and death. Nearly 2,000 children die every year as a result of being shaken.

Physicians may have difficulty initially diagnosing SBS because there are usually few witnesses to give a reliable account of the events leading to the trauma, few if any external injuries, and, upon close examination, the physical findings may not agree with the account given. A shaken baby may present one or

Shaken baby syndrome is a collective term for the internal head injuries a baby or young child sustains from being violently shaken. Because of the fragile state of an infant's brain tissue and blood vessels, when a baby is vigorously shaken by the chest, as shown in the illustration above, the whiplash motion repeatedly jars the baby's brain with extreme force, causing serious internal damage and bleeding. Nearly 2,000 American children die annually from this condition.

more signs, including vomiting; difficulty breathing, sucking, swallowing, or making sounds; seizures; and altered consciousness.

Diagnosis

To diagnose SBS, physicians look for at least one of three classic conditions: bleeding at the back of one or both eyes (retinal hemorrhage), subdural hematoma, and cerebral edema. The diagnosis is confirmed by the results of either a computed tomography scan (CT scan) or magnetic resonance imaging (MRI).

Treatment

Appropriate treatment is determined by the type and severity of the trauma. Physicians may medically manage both internal and external injuries. Behavioral and educational impairments as a result of the injuries require the attention of additional specialists. Children with SBS may need physical therapy, speech therapy, vision therapy, and special education services.

Alternative treatment

There is no alternative to prompt medical treatment. An unresponsive child should never be put to bed, but must be taken to a hospital for immediate care.

Key terms

Cerebral edema — Fluid collecting in the brain, causing tissue to swell.

Hematoma — A localized accumulation of blood in tissues as a result of hemorrhaging.

Hemorrhage — A condition of bleeding, usually severe.

Retinal hemorrhage — Bleeding of the retina, a key structure in vision located at the back of the eye.

Subdural hematoma — A localized accumulation of blood, sometimes mixed with spinal fluid, in the space of the brain beneath the membrane covering called the dura mater.

Prognosis

Sadly, children who receive violent shaking have a poor prognosis for complete recovery. Those who do not die may experience permanent blindness, mental retardation, seizure disorders, or loss of motor control.

Prevention

Shaken baby syndrome is preventable with public education. Adults must be actively taught that shaking a child is never acceptable and can cause severe injury or death.

When the frustration from an incessantly crying baby becomes too much, caregivers should have a strategy for coping that does not harm the baby. The first step is to place the baby in a crib or playpen and leave the room in order to calm down. Counting to 10 and taking deep breaths may help. A friend or relative may be called to come over and assist. A calm adult may then resume trying to comfort the baby. A warm bottle, a dry diaper, soft music, a bath, or a ride in a swing, stroller, or car may be offered to soothe a crying child. Crying may also indicate pain or illness, such as from abdominal cramps or an earache. If the crying persists, the child should be seen by a physician.

shak·en baby syndrome (shkn)

n.

A syndrome in infants in which brain injury is caused by shaking of such violence that the child's brain rebounds against the skull, resulting in bruising, swelling, and bleeding of the brain and often leading to permanent, severe brain damage or death.

shaken baby syndrome,

a condition of whiplash-type injuries, ranging from bruises on the arms and trunk to retinal hemorrhages, coma, or convulsions, as observed in infants and children who have been violently shaken. This form of child abuse often results in intracranial bleeding from tearing of cerebral blood vessels.

Whiplash shaken baby syndrome Forensic medicine A severe form of child abuse that may be either fatal, or leave its victim with permanent neurologic sequelae; severe shaking of an infant–who has virtually no neck muscle tone, may cause bilateral subdural hematomas–due to laceration of the veins bridging the dura mater and cerebral cortex.
