Delirium tremens


Definition:

Delirium tremens is a severe form of alcohol withdrawal that involves sudden and severe mental or nervous system changes.

Alternative Names:

DTs; Alcohol withdrawal - delirium tremens

Causes, incidence, and risk factors:

Delirium tremens can occur when you stop drinking alcohol after a period of heavy drinking, especially if you do not eat enough food.

Delirium tremens may also be caused by head injury, infection, or illness in people with a history of heavy alcohol use.

It is most common in people who have a history of alcohol withdrawal. It is especially common in those who drink 4 - 5 pints of wine or 7 - 8 pints of beer (or 1 pint of "hard" alcohol) every day for several months. Delirium tremens also commonly affects people who have had an alcohol habit or alcoholism for more than 10 years.

Symptoms:

Symptoms most often occur within 48-96 hours after the last drink. However, they may occur up to 7 - 10 days after the last drink.

Symptoms may get worse quickly, and can include:

Other symptoms that may occur:

Signs and tests:

Delirium tremens is a medical emergency.

The health care provider will perform a physical exam. Signs may include:

  • Heavy sweating
  • Increased startle reflex
  • Irregular heartbeat
  • Problems with eye muscle movement
  • Rapid heart rate
  • Rapid muscle tremors

The following tests may be done:

Treatment:

The goals of treatment are to:

  • Save the person's life
  • Relieve symptoms
  • Prevent complications

A hospital stay is needed. The health care team will regularly check:

  • Blood chemistry results, such as electrolyte levels
  • Body fluid levels
  • Vital signs (temperature, pulse, rate of breathing, blood pressure)

Symptoms such as agitation, seizures, and irregular heartbeat are treated with the following medications:

  • Sedatives such as diazepam or lorazepam
  • Anticonvulsants such as phenobarbital

The patient may need to be put into a sedated state for a week or more until withdrawal and DTs are finished. Benzodiazepine medications such as diazepam or lorazepam also help treat seizures, anxiety, and tremors.

Antipsychotic medications such as haloperidol may sometimes be needed for persons with severe psychotic symptoms, especially if they have an underlying problem such as schizophrenia. However, these drugs should be avoided if possible because they may contribute to seizures.

Long-term preventive treatment should begin after the patient recovers from immediate symptoms. This may involve a "drying out" period, in which no alcohol is allowed. Total and lifelong avoidance of alcohol (abstinence) is recommended for most people who go through withdrawal. The person should receive treatment for alcohol use or alcoholism, including:

  • Counseling
  • Support groups (such as Alcoholics Anonymous)

The patient should be tested, and if needed, treated for other medical problems that can occur with alcohol use. Such problems may include:

Support Groups:

Expectations (prognosis):

Delirium tremens is serious and may be life threatening. Some symptoms related to alcohol withdrawal may last for a year or more, including:

  • Emotional mood swings
  • Feeling tired
  • Sleeplessness
Complications:
  • Injury from falls during seizures
  • Injury to self or others caused by mental state (confusion/delirium)
  • Irregular heartbeat, may be life threatening
  • Seizures
Calling your health care provider:

Go to the emergency room or call the local emergency number (such as 911) if you have symptoms. Delirium tremens is an emergency condition.

Prevention:

Avoid or reduce the use of alcohol. Get prompt medical treatment for symptoms of alcohol withdrawal.
