Patients experiencing AWS can be treated in inpatient or outpatient settings depending on the severity of the withdrawal. A score £8 indicates absent or very mild withdrawal 9 to 14 indicates mild withdrawal 15 to 20 indicates moderate withdrawal and a score of >20 indicates severe withdrawal. Nine of the 10 signs and symptoms can be rated in severity from 0 to 7 and one from 0 to 4. These include nausea and vomiting, auditory disturbances, headache, tactile disturbances, paroxysmal sweats, agitation, tremor, visual disturbances, orientation and clouding of sensorium, and anxiety. The CIWA-Ar lists 10 signs and symptoms of withdrawal that can be quantified in order to evaluate the severity of the syndrome. 16 This tool is used to monitor withdrawal signs and symptoms and assess the need for medication. The Clinical Institute for Withdrawal Assessment for Alcohol-revised (CIWA-Ar) scale is a validated instrument to assess the severity of AWS. This is related to the frequent changes in GABA and NMDA receptors as described above. 12,13Ī process known as kindling has been proposed to explain the decrease in time of onset and increase in severity of symptoms in patients who have undergone repeated episodes of withdrawal. At the same time, glutamate is activated, which in turn increases the function of the NMDA receptors. 13,15 During withdrawal, GABA levels decrease below normal capacity, which ultimately leads to hyperactivity of the nervous system. The presence of alcohol inhibits the function of the N-methyl-d-aspartate (NMDA) receptor, leading to the sedative and anxiolytic effects of alcohol as well as to impaired memory and the generation of potentially life-threatening seizures. Together these neurotransmitters maintain neurochemical balance in the brain. Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter and glutamate is the primary excitatory neurotransmitter. Two neurotransmitters in the brain are affected by chronic alcohol consumption and play a major role in AWS. 10,13 The mortality rate for patients who experience DTs has been reported to be from 1% to 15%. The primary symptoms of DTs consist of diaphoresis, fever, nightmares, agitation, global confusion, disorientation, visual and auditory hallucinations, and cardiovascular and metabolic complications. 13 Stage 4 includes the previous symptoms in conjunction with DTs. 5 Stage 3 is characterized by similar symptoms with an increase in severity and the addition of seizures. 10,12 Stages 1 and 2 of withdrawal are characterized by milder symptoms, which may cause a patient not yet in treatment to begin consuming alcohol again. 1,11ĪWS consists of three or four (depending on the source) stages of severity, which are based on the symptoms a patient is experiencing. More severe consequences of alcohol withdrawal, especially seizures or delirium tremens (DTs), occur in 100 bpm) increased hand tremor insomnia nausea or vomiting transient visual, tactile, or auditory hallucinations or illusions psychomotor agitation anxiety or tonic-clonic seizures. Approximately one-half of patients with alcohol dependence will develop clinically relevant symptoms of withdrawal. 1 According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), alcohol use disorders are medical conditions that occur in patients experiencing distress or harm related to their consumption of alcoholic beverages. Versed antidote manual#The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) combines alcohol abuse and alcohol dependence into the newly termed alcohol use disorder (AUD). Although a variety of drugs have some utility in treating this disorder, the benzodiazepines remain the agents of choice. Pharmacotherapy is often necessary for treating patients with AWS to manage the symptoms of withdrawal, prevent the progression to serious complications, and bridge these patients to treatment for maintaining long-term recovery. Depending upon the severity of withdrawal symptoms, patients may be treated in the inpatient or outpatient setting. Mild symptoms can occur within hours after the last drink and, if left untreated, may progress to more severe, life-threatening symptoms. ABSTRACT: Alcohol withdrawal syndrome (AWS) can occur when an individual stops or even significantly reduces alcoholic consumption after a prolonged period of use.
