Pupillary Changes In the early stages of alcoholic intoxication the pupils are said to dilate purchase biaxin 500mg with mastercard, often becoming pinpoint as the level of intoxication advances purchase 250 mg biaxin overnight delivery, particularly when the state of coma is reached (154) order 500mg biaxin mastercard. However, some commentators report the pupils as being normal-sized in alcohol intoxication (155), with current advice favoring the view that pupil size may be normal or dilated (156). Alcohol may slow the pupillary response to light, such an effect being one of the more reliable eye signs of intoxication, albeit a difficult one to detect clinically (151,157). Because it requires a high degree of coordination, it can be a sensitive index of alcohol intoxication 312 Stark and Norfolk (158). Reliable changes in speech are produced at blood alcohol levels above 100 mg/100 mL, although the effects of lower blood alcohol levels have been variable (159). Cardiovascular Effects Moderate doses of alcohol cause a slight increase in blood pressure and pulse rate (160,161). However, the most prominent effect with higher doses is a depression of cardiovascular functions. This depression is probably a com- bination of central effects and direct depression of the myocardium (144). Metabolic Effects Forensic physicians must be aware that severe hypoglycemia may accom- pany alcohol intoxication because of inhibition of gluconeogenesis. Alcohol- induced hypoglycemia, which develops within 6–36 hours of heavy drinking, typically occurs in an undernourished individual or one who has not eaten for the previous 24 hours. The usual features of hypoglycemia, such as flushing, sweating, and tachycardia, are often absent, and the person may present in coma. Death From Alcohol Poisoning Alcohol intoxication may result in death owing to respiratory or circula- tory failure or as a result of aspiration of stomach contents in the absence of a gag reflex. Levels of blood alcohol above 500 mg/100 mL are considered to be “probably fatal” (162), although survival at much higher concentrations is now well documented. In 1982, for example, the case of a 24-year-old woman with a blood alcohol level of 1510 mg/100 mL was reported. She had gone to the hospital complaining of abdominal pain and was noted to be conscious but slightly confused. Two days later, her pain had eased, her blood alcohol level fallen, and she was able to leave the hospital and return home (163). Death associated with blood alcohol levels below 350 mg/100 mL sug- gests that other complicating factors are present. Most commonly, this will be an interaction between alcohol and some other drug that has also been ingested. Diagnosis of Intoxication The terms alcohol intoxication and drunkenness are often used inter- changeably. However, a distinction between these terms is justified because people may exhibit behavioral changes associated with drunkenness when they believe they have consumed alcohol but actually have not (164). Thus, the diagnostic features of alcoholic intoxication developed by the American Psy- chiatric Association include a requirement that there must have been recent ingestion of alcohol (Table 16) (165). Table 17 Pathological States Simulating Alcohol Intoxication • Severe head injuries • Metabolic disorders (e. This is particularly important when assessing an intoxi- cated detainee in police custody. Indeed, the doctor’s first duty in examining such individuals should be to exclude pathological conditions that may simu- late intoxication (154) (Table 17), because failure to do so may lead to deaths in police custody (166). Alcohol Dependence Alcohol abuse and dependence is a major risk factor for serious health, social, and economic problems (167). Early identification of those who are dependent on alcohol increases the possibility of successful treatment, and 314 Stark and Norfolk brief intervention by the forensic physician seems both feasible and accept- able (124,168). Although not yet validated in police custody, brief interven- tions show a high acceptance among drinkers in licensed premises (169). However, obtaining accurate and reliable information about a person’s drinking habits can be extremely difficult because heavy drinkers tend to underestimate or deliberately lie about their alcohol consumption (170). The main features dif- ferentiating alcohol dependence from alcohol abuse are evidence of toler- ance, the presence of withdrawal symptoms, and the use of alcohol to relieve or avoid withdrawal. However, there is no need to treat those who simply abuse alcohol and who do not have a history of alcohol withdrawal. Alcohol Withdrawal Many alcoholics develop symptoms of withdrawal when in custody. When alcohol intake is abruptly stopped on incarceration, the com- pensatory changes give rise to signs and symptoms of withdrawal (176). The severity of the symptoms depends mainly on the amount and duration of alco- hol intake, although other factors, such as concurrent withdrawal from other drugs, like benzodiazepines, may contribute to the clinical picture (177). Uncomplicated Alcohol Withdrawal This is the most frequent and benign type, usually occurring some 12–48 hours after alcohol intake is reduced, although it can develop as early as 6 hours after drinking has stopped. The essential features are a coarse tremor of the hands, tongue, and eyelids, together with at least one of the following: Substance Misuse 315 • Nausea and vomiting. If symptoms are mild, it is safe to recommend simple observation, but significant tremor and agitation will usually require sedation. The drugs of choice are long-acting benzodiazepines, which will not only treat alcohol with- drawal symptoms but will also prevent later complications (178). The starting dosages depend on the severity of the withdrawal, but 20 mg of chlordiazep- oxide, or 10 mg of diazepam, both given four times a day, will generally be appropriate (179). Usually the benzodiazepines should not be started until such time as the blood alcohol level has reached zero (180). However, detained persons with marked alcohol dependence may develop withdrawal symptoms before this point is reached. In these circumstances, it is both safe and reasonable to initiate therapy when the blood alcohol level has reached 80 mg/100 mL or thereabouts. Alcohol Withdrawal Delirium The essential diagnostic feature of this disorder is a delirium that devel- ops after recent cessation of or reduction in alcohol consumption. Tradition- ally referred to as delirium tremens, this withdrawal state typically begins 72–96 hours after the last drink, so it is uncommon within the normal span of detention in police custody. The delirium is characterized by impaired atten- tion and memory, disorganized thinking, disorientation, reduced level of con- sciousness, perceptual disturbances, and agitation. The disorder usually coexists with other features of alcohol withdrawal, for example, autonomic hyperac- tivity, which is usually severe.
