The dose makes the poison What is it that is not a poison? All things are poison and nothing is without poison. Solely, the dose determines that a thing is not a poison. --Paracelsus (1493–1541), the Renaissance Father of Toxicology, in his Third Defense Erickson TB, The approach to the patient with an unknown overdose, Emerg Med Clin N Am 25 (2007) 249–281 http://en.wikipedia.org/wiki/Paracelsus

Abuse versus dependence: DSM IV-TR • Alcohol abuse • A. A maladaptive pattern of drinking, leading to clinically significant impairment or distress, as manifested by at least one of the following occurring within a 12-month period: • Recurrent use of alcohol resulting in a failure to fulfill major role obligations at work, school, or home (e.g., repeated absences or poor work performance related to alcohol use; alcohol-related absences, suspensions, or expulsions from school; neglect of children or household) • Recurrent alcohol use in situations in which it is physically hazardous (e.g., driving an automobile or operating a machine when impaired by alcohol use) • Recurrent alcohol-related legal problems (e.g., arrests for alcohol-related disorderly conduct) • Continued alcohol use despite having persistent or recurrent social or interpersonal problems caused or exacerbated by the effects of alcohol (e.g., arguments with spouse about consequences of intoxication). • B. Never met criteria for alcohol dependence. • Alcohol dependence • A. A maladaptive pattern of drinking, leading to clinically significant impairment or distress, as manifested by three or more of the following occurring at any time in the same 12-month period: • Need for markedly increased amounts of alcohol to achieve intoxication or desired effect; or markedly diminished effect with continued use of the same amount of alcohol • The characteristic withdrawal syndrome for alcohol; or drinking (or using a closely related substance) to relieve or avoid withdrawal symptoms • Drinking in larger amounts or over a longer period than intended. • Persistent desire or one or more unsuccessful efforts to cut down or control drinking • Important social, occupational, or recreational activities given up or reduced because of drinking • A great deal of time spent in activities necessary to obtain, to use, or to recover from the effects of drinking • Continued drinking despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to be caused or exacerbated by drinking. • B.

MKSAP question • A 39-year-old man is admitted to the hospital for new-onset agitation, fluctuating level of consciousness, and tremors. He is diagnosed with acute alcoholic hepatitis.
MKSAP Question • On physical examination, temperature is 38.8°C (101.8°F), blood pressure is 95/55 mm Hg, pulse rate is 130/min, and respiration rate is 30/min. Jaundice is noted. The abdomen is protuberant with ascites but is soft, with no abdominal rigidity or guarding. There is no blood in the stool. The patient is agitated and disoriented, is unable to maintain attention, and appears to be having visual hallucinations. He believes that the nurse has stolen his wallet (which is in his bedside drawer) in order to obtain his identity. He is diaphoretic and tremulous. Asterixis is absent, and the remainder of the neurologic examination is normal.
MKSAP Question • Q: Which of the following is the most appropriate management? • A. Ceftriaxone B. CT of the headC. HaloperidolD. Lactulose enemaE. Lorazepam
DeliriumDiagnostic Criteria • A disturbance in attention (i.e., reduced ability to direct, focus, sustain, and shift attention) and awareness (reduced orientation to the environment). • The disturbance develops over a short period of time (usually hours to a few days), represents a change from baseline attention and awareness, and tends to fluctuate in severity during the course of a day. • An additional disturbance in cognition (e.g., memory deficit, disorientation, language, visuospatial ability, or perception). • The disturbances in Criteria A or C are not better explained by another preexisting, established, or evolving neurocognitive disorder and do not occur in the context of a severely reduced level of arousal, such as coma. • There is evidence from the history, physical examination, or laboratory findings that the disturbance is a direct physiological consequence of another medical condition, substance intoxication or withdrawal (i.e., due to a drug of abuse or to a medication), or exposure to a toxin, or is due to multiple etiologies.

Differentiate delirium tremens from other alcohol withdrawal syndromes • 5% of patients with alcohol withdrawal • Constellation of symptoms: confusion, hallucinations, fever (with or without evidence of infection), and autonomic hyperresponsiveness with hypertension and profound tachycardia • Suspect in any agitated patient withdrawing from alcohol with BP >140/90 mm Hg, HR > 100/min, T > 101 Fahrenheit • Mortality 5-15% Erwin WE et al, Delirium tremens, Southern Medical Journal (May 1998, 91:5), 425-432.
MKSAP Question • Correct answer: E. Lorazepam. • The most appropriate treatment is lorazepam for delirium tremens syndrome. The term delirium tremens is nearly universally used to refer to delirium due to alcohol withdrawal syndrome. The syndrome usually presents 48 to 96 hours after cessation of drinking, can last up to 2 weeks, and is usually exacerbated at night. The syndrome is characterized by impaired level of consciousness and disorientation (which may fluctuate significantly), reduced attention and global amnesia, impaired cognition and speech, and often hallucinations (usually tactile and/or visual) and delusions (persecutory). The condition can be rapidly fatal if not treated appropriately and aggressively. Seizure activity can occur. Benzodiazepines are the treatment of choice, with doses given as needed based on exhibited signs and symptoms consistent with alcohol withdrawal.
Delirium tremens • Key Points • Delirium tremens is characterized by fluctuating level of consciousness, disorientation, reduced attention, global amnesia, impaired cognition and speech, and often hallucinations and delusions.
Risk factors for severe course of AWS, including seizures and delirium • 1. Prior episodes of AWS requiring detoxification, including seizures or delirium (kindling) • 2. Grade 2 severity or higher on presentation (CIWA-Ar Score >10) • 3. Advanced age • 4. Acute or chronic comorbid conditions, including alcoholic liver disease, co-intoxications, • trauma, infections, sepsis • 5. Detectable blood alcohol level on admission • 6. Use of “eye opener,” high daily intake of alcohol, or number of drinking days/month • 7. Abnormal liver function (serum aspartate aminotransferase activity >80 U/L) • 8. Prior benzodiazepine use • 9. Male sex • Abbreviation: CIWA-Ar, Clinical Institute of Withdrawal Assessment for Alcohol, revised. Carlson RW et al, Alcohol Withdrawal Syndrome, Crit Care Clin 28 (2012) 549–585
Potential indications for ICU management • 1. Advanced Stage 2 or greater alcohol withdrawal syndrome • 2. Critical comorbid conditions including: trauma; severe sepsis; respiratory failure; acute respiratory distress syndrome; hemodynamic instability; gastrointestinal bleeding; hepatic failure; pancreatitis; rhabdomyolysis; co-intoxication; coagulopathies; acute CNS process; cardiac arrhythmias, ischemia, or congestive failure; severe fluid or electrolyte defects; renal failure; persistent fever; or complex acid-base defects • 3.
