How Birth Injuries Occur
Damage to the developing brain before, during, or after birth causes cerebral palsy. Birth injuries refer to damage that occurs during labor, delivery, or shortly after delivery. Most cases of fetal brain injury happen before babies are born, but a small percentage of injuries take place in the delivery room.
Types of Birth Injuries
A birth injury that causes cerebral palsy can come in many forms. There are several risk factors that increase the likelihood of a birth injury occurring.
Some of these factors include:
- Loss of oxygen or blood flow to the baby’s brain
- Blood clotting
- Placental abnormalities including poor perfusion or abruption
- Maternal high blood pressure
- Improper medical care
- Prenatal drug use
- Premature birth or low birth weight
- Multiple gestation
- Injury to the brain
Factors that Increase Birth Injury Chances
There are four basic types of brain damage that result from a birth injury. Understanding these factors can help explain how damage to the developing brain can cause cerebral palsy.
Hypoxic ischemic encephalopathy (HIE) – This is the medical term for brain damage caused by decreased blood and oxygen levels to the brain. This is the leading preventable birth injury affecting the brain. HIE leads to the destruction of brain cells and tissue, predominantly in the motor cortex of babies who develop cerebral palsy. It may occur during pregnancy or delivery. If HIE occurs during pregnancy, it may lead to another type of brain damage, periventricular leukomalacia.
Periventricular leukomalacia (PVL) – This is the death of white matter in the brain and the subsequent loss of brain tissue. White matter contributes to the brain’s ability to learn and function. PVL is specifically caused by a lack of blood flow to the periventricular part of the brain where white matter is found. It is made of nerve fibers that relay signals for motor function. It is caused by loss of oxygen to the fetal brain and can co-occur with bleeding in the periventricular region. Placental failure and infection may cause PVL.
Intracranial hemorrhage – Bleeding in the brain is known as intracranial hemorrhage. The most common cause of intracranial hemorrhaging is fetal stroke. Blocked or damaged blood vessels in the child’s brain can cause a stroke and subsequent hemorrhaging. High blood pressure, complications with the placenta and infections in the mother may lead to intracranial hemorrhaging. Pelvic inflammatory disease, an infection of the female reproductive system, is a common cause of bleeding in the brain of the fetus. This is most common in premature infants.
Cerebral dysgenesis – Anything that inhibits the healthy development of the fetal or infant brain can cause abnormal development of the motor control center. Cerebral dysgenesis is just a medical term for abnormal development of the fetal brain. This generally occurs during the pregnancy when the brain is forming. Direct injury to the baby’s head during or shortly after delivery and infection can also cause cerebral dysgenesis. Infections can mutate the genes responsible for developing motor function.
Preventable Birth Injuries
Some birth injuries that lead to cerebral palsy are preventable. The source of these cases is often negligence on the part of the obstetrics team.
Preventable birth injuries are usually caused by:
- Failing to detect infections during pregnancy
- Adverse effects from drugs or surgery
- Neglecting proper heart rate monitoring during delivery
- Not performing a medically advisable cesarean section
- Improper use of delivery instruments, such as forceps
- Failing to detect issues with the umbilical cord
- Gross mismanagement of normal delivery procedure
- Failing to treat severe jaundice in the newborn
These lapses in medical judgment can cause cerebral palsy by inhibiting normal development, depriving the fetus of blood and oxygen or causing physical trauma. Any of these factors can cause damage to the developmental brain.
Forceps and Vacuum Extractors
The use of forceps and vacuum extractors during a complicated childbirth can increase the chances of a child sustaining an injury during birth.
Forceps and vacuum extractors come with several risk factors, including:
- Brain or nerve damage
- Skull fractures
- Fetal stroke
- Cerebral palsy
The improper use of these birth-assisting tools can lead to cerebral palsy when direct pressure is applied to an infant’s head during delivery. When birth-assisting tools are placed incorrectly, this can result in lifelong damage to the skull, eyes, brain, nerves and facial muscles.
Erb’s palsy is commonly confused with cerebral palsy due to the various symptoms associated with these forms of paralysis and nerve damage. The most obvious symptom that sets Erb’s palsy apart from other conditions is when the paralysis affects the voluntary movement in the upper arm and rotation in the lower arm.
The cause of this condition can vary, but it typically occurs during a difficult child birth where a shoulder dystocia occurs. There are a number of risk factors associated with this condition, and treatment for Erb’s palsy depends on the severity of the paralysis.
Getting Legal Compensation
Parents of a child whose cerebral palsy was caused by a preventable birth injury may be entitled to legal compensation. Cerebral palsy is a condition that requires lifelong treatment, and the costs of raising a child with CP are many times greater than raising a child without a disability.
Parents have the right to seek compensation through a lawsuit. There are attorneys who are highly experienced in handling cerebral palsy cases. They are able to sift through all the available evidence to determine whether the parents have a strong case. Get connected with an experienced birth injury lawyer for a free case review.
