Anoxic Brain Injuries: Definition, Causes, and Medical Malpractice

When brain injury is caused by someone else’s negligence (even a doctor’s), victims may be entitled to financial compensation for their damages.

About Anoxia and Hypoxia

The human brain requires a constant supply of oxygen. Any interruption to that supply — even if it is only partial or temporary — can cause serious, debilitating, or life-threatening complications.

When the brain’s oxygen supply is completely cut off, it’s called anoxia. If the brain is still getting some oxygen but not enough, it’s called hypoxia.

What Is a Hypoxic-Anoxic Injury?

Doctors tend to talk about these two conditions together, referring to them collectively as a hypoxic-anoxic injury (HAI). That’s because hypoxia can quickly lead to anoxia, so doctors need to take urgent action to prevent further oxygen deprivation in either situation.

Why so urgent? Oxygen makes its way to the brain through blood. Brain cells can die in as little as four minutes without adequate blood flow, resulting in permanent brain damage. Complications may include life-long disability or death.

Given the emergent nature of any interruption to cerebral blood flow, health care providers should initiate treatment immediately — and take careful measures to avoid anoxic brain injury in the first place whenever possible.

What Causes an Anoxic Brain Injury?

Because the heart is responsible for pumping a fresh supply of healthy blood throughout the body on a regular basis, any condition that threatens heart health (including heart disease, heart attack, and cardiac arrest) can lead to an anoxic brain injury.

Similarly, many strokes are caused by a blood clot in the brain, which can starve the affected area of oxygenated blood. Pulmonary embolisms (blood clots in the lungs) can also travel to the brain and threaten blood supply.

Other causes of a hypoxic-anoxic brain injury (HAI) includes:

  • Anesthesia errors
  • Drug overdose
  • Smoke inhalation
  • Carbon monoxide poisoning
  • Severe bodily injury (trauma) resulting in substantial blood loss
  • Auto accidents
  • Suffocation
  • Choking
  • Drowning
  • Severe drops in blood pressure
  • High altitude sickness
  • Electrocution
  • Severe brachial asthma

What Doctors Should Look For

The symptoms of an anoxic brain injury can come on slowly and may appear to be vague and nonspecific at first. Doctors should carefully consider any hypoxia symptom that arises after a medical event associated with HAI. For example, doctors who have successfully treated a heart attack in an Emergency Department should still be on the lookout for signs of emerging hypoxia or an HAI, which may include:

  • Confusion
  • Changes in personality or behavior
  • Memory loss / amnesia
  • Difficulty recalling basic information (address, social security number, etc.)
  • Poor motor skills / decline in coordination
  • Poor judgments
  • Speech difficulties (e.g. difficulty speaking spontaneously, speaking coherently, or forming full and fluid sentences)
  • Difficulty understanding others or processing visual information
  • Becoming easily distracted / Difficulty concentrating
  • Hallucinations / visual disturbances
  • Weakness in the extremities
  • Difficulty following directions
