Delirium tremens (DTs; lit. 'mental disturbance with shaking') is a rapid onset of confusion usually caused by withdrawal from alcohol.[2] When it occurs, it is often three days into the withdrawal symptoms and lasts for two to three days.[2] Physical effects may include shaking, shivering, irregular heart rate, and sweating.[1] People may also hallucinate.[2] Occasionally, a very high body temperature or seizures (colloquially known as "rum fits")[5][6] may result in death.[2]
Delirium tremens typically occurs only in people with a high intake of alcohol for more than a month, followed by sharply reduced intake.[7] A similar syndrome may occur with benzodiazepine and barbiturate withdrawal. In a person with delirium tremens, it is important to rule out other associated problems such as electrolyte abnormalities, pancreatitis, and alcoholic hepatitis.[2]
Prevention is by treating withdrawal symptoms using similarly acting compounds to taper off the use of the precipitating substance in a controlled fashion.[2] If delirium tremens occurs, aggressive treatment improves outcomes.[2] Treatment in a quiet intensive care unit with sufficient light is often recommended.[2] Benzodiazepines are the medication of choice with diazepam, lorazepam, chlordiazepoxide, and oxazepam all commonly used.[7] They should be given until a person is lightly sleeping.[2] Nonbenzodiazepines are often used as adjuncts to manage the sleep disturbance associated with condition. The antipsychotic haloperidol may also be used[2] in order to combat the overactivity and possible excitotoxicity caused by the withdrawal from a GABA-ergic substance. Thiamine (vitamin B1) is recommended to be given intramuscularly,[2] because long-term high alcohol intake and the often attendant nutritional deficit damages the small intestine, leading to a thiamine deficiency, which sometimes cannot be rectified by supplement pills alone.
Mortality without treatment is between 15% and 40%.[4] Currently death occurs in about 1% to 4% of cases.[2]
About half of people with alcoholism will develop withdrawal symptoms upon reducing their use.[2] Of these, 3% to 5% develop DTs or have seizures.[2]
The name delirium tremens was first used in 1813; however, the symptoms were well described since the 1700s.[7] The word "delirium" is Latin for "going off the furrow", a plowing metaphor for disordered thinking.[4] It is also called the shaking frenzy and Saunders-Sutton syndrome.[4] There are numerous nicknames for the condition, including "the DTs" and "seeing pink elephants".
