In a perfect world, patients with heavy alcohol dependence should be identified before elective surgical procedures and referred to alcohol counseling services. In the medical field, the Hospital Anxiety and Depression Scale (HADS) is a well-established self-administered 14-item scale that has two subscales that assess anxiety (7 items) and depression (7 items). The HADS was developed by Zigmond and Snaith in 1983 to evaluate the degree of anxiety and depression in non-psychiatric hospitals and clinics [15].

However, interpretation of UAC is a lot easier, because of the high correlation between UAC and BAC as reported from controlled drinking studies (48) and in apprehended drivers (45). The first two versions of the Dubowski table were published in 1957 and 1970, and these included information about UAC alongside BAC (41). The concentrations of ethanol in urine were calculated from the BAC by multiplying with a factor of ∼1.33, which corresponds to the average UAC/BAC ratio for a freshly voided specimen in the post-absorptive phase of the BAC curve (44, 45).

Consumption of alcohol lowers a person’s inhibitions, and this makes them more likely to take risks, such as driving a motor vehicle when drunk and/or engaging in unsafe sex (4, 5). The broad range of behavioral changes resulting from excessive drinking are common knowledge and must have been known for hundreds of years, because alcohol (ethanol) is our oldest recreational drug (6). Alcohol withdrawal syndrome is characterized by tremor, gastric upset, sweating, hypertension, hyper-reflexia, anxiety, and agitation progressing to delirium, hallucinations, and seizures.

Those subjects showing cerebellar degeneration exhibited hypometabolism in the superior cerebellar vermis in addition to the frontal cerebral cortex. The severity of the clinical neurological impairment significantly correlated with the degree of hypometabolism in the superior cerebellar vermis and the medial frontal cerebral cortex. The correlation between clinical symptoms and hypoactivity in the cerebellar vermis was restricted to ACD patients while the hypometabolism in the medial frontal cortex correlated with alcoholic patients with and without ACD. Certain anesthetic drugs, especially narcotics, are cleared by the liver, and decreased liver metabolism of narcotics can lead to relative overdoses. Chronic heavy alcohol use can also lead to cardiomyopathy with depressed ejection of blood from the heart, causing low blood pressures during and after anesthesia.

However, from this study it is not clear how much acute intoxication contributed to these effects. A subsequent study with low dose alcohol in healthy control subjects showed that acute oral administration of both 0.25 g/kg and 0.5 g/kg significantly reduced brain glucose metabolism 40–50 min after alcohol intake, but the responses differed between the two doses (Volkow et al., 2006). While 0.25 g/kg reduced metabolism in the cortical regions, 0.5 g/kg dose showed reduction in the cortical regions as well as the subcortical regions, i.e., cerebellum, mesencephalon, basal ganglia and the thalamus. Alcoholic effects on cognitive performance were only minimal from placebo vs. ethanol as well as between the two doses.

A brief schematic flowchart for management of alcohol intoxication in the emergency setting is presented in Figure 3. Functional connectivity in the BNST-ventromedial prefrontal cortex was weaker in women in early abstinence during unpredictable threat cues and stronger in men during unpredictable neutral cues. People in the healthy group who had higher anxiety scores showed weaker connectivity in these regions during unpredictable cues than people in the early abstinent group. Here, we provide a brief overview of common medical problems that may be related to your patients’ consumption of alcohol.

• Another early study of the relationship between signs and symptoms of intoxication and BAC was reported by Walter W. Jetter in 1938 (35).
• Neuroleptic drugs are preferred to benzodiazepines when alcohol withdrawal is not the primary cause of delirium.
• Acetaldehyde build-up leads to symptoms such as nausea and vomiting which deter the user from further alcohol intake.
• Alcohol use is an independent risk factor for the development of acute confusion or delirium after operation.
• In addition to those mentioned in Table 1, some features of alcohol intoxication seen with increasing blood alcohol concentration (BAC) are discussed in Table 2.

General management of intoxicated patients in the emergency setting

In the OF task, the exploration of the center as opposed to periphery indicate increased anxiety and familiarization to the environment. These behavioral assessments indicate cognitive impairment after acute alcohol intoxication. Therefore, our study showed a strong relationship between hypometabolism in the temporal lobe and impairment in spatial cognition after acute alcohol intoxication. Additional cognitive responses in response to acute alcohol involving the hippocampus such as spatial reference memory, contextual learning memory, trace conditioning and spontaneous alteration have been elegantly reviewed previously and will not be addressed here (Van Skike et al., 2019). Recently, we conducted a study using a mouse model of binge alcohol exposure and measured brain glucose metabolism and cognitive performance in the same cohort of mice (Jacob et al., 2019). Our model consisted mice, each receiving a continuous intravenous administration of a bolus dose of alcohol (1.5 g/kg) referred to a bolus infusion for over a 20 min period.

During police investigations of alcohol-related crimes, such as impaired driving and sexual assault, expert witnesses are often asked to interpret a person’s BAC in relation to the impairment effects of ethanol on the central nervous system. Questions might arise about changes in a person’s demeanor and personality when under the influence of alcohol or their ability to perform skilled tasks, such as driving. An expert witness might also be required to express an opinion about incapacitation after engaging in heavy stages of alcohol poisoning drinking, such as whether a person was capable of forming intent or making rational decisions or giving consent with a certain BAC (8, 9). Though cocaine and other stimulants have traditionally not been commonly abused in India, their use is gradually rising, especially in bigger cities. Presentation of cocaine intoxication is in the form of euphoric mood, increased psychomotor activity, severe agitation, impaired attention, auditory hallucinations, paranoid ideation, confusion, anxiety, and hypervigilance.

• We also investigated the duration of hospitalization and in-hospital death as secondary outcomes.
• Benzodiazepines have several clinical applications including treatment of sleep and anxiety disorders.
• In addition, some recent advancements in biomedical research are introduced with reference to hepatic and cardiovascular influences of alcohol, factors relevant to the development of alcohol dependence, and biological targets for the treatment of alcohol dependence.
• Multiple substances are generally mixed together with the aim of enhancing the psychoactive effect, off-setting the adverse effects, and alleviating the withdrawal symptoms.
• Figure 2 shows percentages of apprehended drivers judged impaired by alcohol in relation to those not considered to be impaired in relation to the measured BAC (58).

The present clinical practice guidelines deal with the assessment and management of patients with substance intoxication presenting to the emergency department. The guidelines present the general considerations while attending to a substance intoxicated patient, followed by general signs of intoxication. Thereafter, details of intoxication with specific substances are discussed, namely, alcohol, cannabis, opioids, benzodiazepines, and other substances.
