Ethanol withdrawal is the most severe type called as delirium tremens (DTs) or alcohol withdrawal delirium (AWD).
It occurs in individuals with a history of chronic, heavy alcohol use, when someone suddenly reduce or stop their alcohol intake.
Early diagnosis and treatment are important since it should be regarded as a medical emergency with a high fatality rate.
The Latin word for delirium tremens is “shaking delirium.” It was initially identified in the early 1800s by doctors who noticed that people with alcoholism had severe neuropsychiatric symptoms.
The defining feature of delirium tremens is profound worldwide confusion. Alcoholics shows symptoms and indicators of magnesium shortage as well as significant overall body magnesium deficiency.
It is not advised to use intravenous ethanol infusions to prevent or cure alcohol withdrawal.
According to the Richmond Agitation Sedation Scale (RASS) or the Clinical Institute Withdrawal Assessment Alcohol Scale Revised (CIWA-Ar), very-high-dose bolus benzodiazepines, with phenobarbital added as necessary, may help reduce the duration of stay in the intensive care unit and the need for mechanical ventilation.
Epidemiology
When alcohol consumption is stopped, fewer than half of people with alcohol dependence experience any severe withdrawal symptoms that call for medication treatment.
It is predicted that 5–10% of people with chronic alcohol addiction would experience delirium tremens (DTs) in their lives.
DTs are only reached by 5% of ethanol withdrawal patients. Serious alcohol withdrawal is more likely to occur in white patients than in black patients.
Withdrawal symptoms in any given alcohol-dependent individual might vary greatly from one episode to the next.
Pediatric patients rarely have delirium tremens because it takes time for the physiologic basis for severe alcohol withdrawal to form.
Anatomy
Pathophysiology
Chloride flow decreases during alcohol withdrawal due to a decrease in GABA-A receptor activation.
The absence of NMDA receptor inhibition may result in delirium and seizures.
The impact of alcohol on the quantity and functionality of brain receptors is linked to excessive nervous system excitability over extended periods of fasting.
Numerous neurotransmitter systems in the brain are impacted by long-term alcohol consumption.
Etiology
The cause of DT is as follows:
Chronic Alcohol Dependence
Abrupt Cessation or Reduction of Alcohol
Neurobiological Mechanisms
Genetic and Individual Susceptibility
Genetics
Prognostic Factors
The death rate for patients with DTs is currently between 5 and 15% despite proper therapy with contemporary intensive care unit management.
Heart arrhythmias and respiratory failure are the most frequent causes of death in people with DTs.
Patients with severe fever, fluid and electrolyte imbalance, or a coexisting illness are most at risk of dying.
Identification of high-risk individuals and the preventative use of benzodiazepines during alcohol detoxification are the main goals of prevention.

Treatment Paradigm
The main medication used to treat alcohol withdrawal is benzodiazepines. It is necessary to use large doses of sedatives to adequately control symptoms.
Patients with DTs are treated with increasing dosages of diazepam and phenobarbital titration based on their scores on the Riker Sedation Agitation Scale (RSAS) (goals 3–4) or the Richmond Agitation Sedation Scale (RASS) (goals 0–2).
The RASS or RSAS is calculated after each dose of diazepam, which is given intravenously in increasing quantities every 10 to 15 minutes up to 100–150 mg per dose.
The intravenous administration of phenobarbital is repeated at doses of 65–260 mg until the target sedation score is achieved if the goal is not achieved.
Propofol is an effect adjunct that can prolong hospital stays but is helpful for intubated patients. Dexmedetomidine may also be utilized, however it should be used carefully in patients who have heart failure or left ventricular dysfunction.
It is not recommended to use sympatholytic medications unless benzodiazepines are also taken in sufficient dosages. Benzodiazepines are the most effective way to prevent and cure seizures brought on by alcohol withdrawal.
The patient should be placed in an isolated, quiet space with little activity or noise.
Maintain dim but consistent lighting to help with orientation and sudden changes from darkness to bright light.
Any furniture, medical equipment, or sharp objects that could injure someone during agitation should be removed.
Reducing excessive stimulation is crucial but stay away from total seclusion or a sterile setting.
Proper awareness about DT should be provided and its related causes with management strategies.
Appointments with specialists and preventing recurrence of disorder is an ongoing life-long effort.
Use of Benzodiazepines
Chlordiazepoxide:
It increases GABA activity, which depresses the limbic and reticular structures as well as all other levels of the central nervous system.
Lorazepam:
It is a sedative hypnotic with a rapid onset of action and a medium duration of effect.
Use of General Anesthetics
Ketamine:
An NMDA antagonist that has a lower risk of respiratory depression.
Propofol:
It acts on both GABA-A and glutamate receptors, while benzodiazepines exclusively act on GABA receptors.
Dexmedetomidine:
The activation of presynaptic alpha-2 adrenergic receptors may be the mechanism of action of acute therapy for agitation linked to bipolar I or II disorder or schizophrenia.
Use of Barbiturates
Phenobarbital:
It shows the effects on the benzodiazepine-GABA-A-chloride receptor complex that increase chloride flux.
Pentobarbital:
Pentobarbital is a short-acting barbiturate cause mood changes at all levels of the CNS.
Use of Vitamins and Nutrients
Dextrose:
With less fluid volume, concentrated dextrose infusions give greater glucose levels and a greater caloric intake.
