Alcohol Intoxication (cont.)

When to Seek Medical Care for Alcohol intoxication

If all home care conditions cannot be assured, or if a caretaker feels uncomfortable monitoring the intoxicated person, or if there is any doubt about the person's condition, then take the person to the nearest hospital's emergency department. In addition, the person may need medical attention to address chronic medical conditions unrelated to the alcohol intoxication. These could be conditions such as diabetes, renal (kidney) failure, or epilepsy (seizures).

Alcohol Intoxication Diagnosis

The doctor will assess the person suspected of alcohol intoxication to answer the following medical questions and provide the appropriate care. Friends or family who accompany an intoxicated person (or person suspected to be intoxicated) to the hospital can provide invaluable information regarding recent events as well as past medical history.

Does the blood alcohol concentration correspond to the physical exam and the person's apparent degree of intoxication?

  • Most importantly, in a lethargic, intoxicated person, a doctor may be more interested in how low the blood alcohol concentration is rather than how high it is. This is because the lower the blood alcohol concentration, the less likely that alcohol explains the abnormal drowsiness.
  • The dilemma: If the blood alcohol concentration is found to be inappropriately low for the apparent degree of intoxication (for example, a blood alcohol concentration of 150 mg/dL in a person who is deeply lethargic), then the doctor must look elsewhere for an explanation. Conversely, a blood alcohol concentration of 300 mg/dL may perfectly explain a stuporous state while masking a coexisting, serious, life-threatening condition.

Is there any evidence of serious physical injury?

  • In people with mild-to-moderate intoxication, the physical exam alone may often be sufficient to exclude serious physical injuries or at least permit a later reassessment.
  • The existence or extent of a head injury may be difficult or impossible to assess in a lethargic, intoxicated person. Important information about the person's medical history and recent activities is often lacking, and a person is usually in no condition to talk coherently.

Are any medical conditions contributing to the person's condition?

  • The assessment of medical conditions in an intoxicated person can be quite complex, as the two often coexist. The doctor will need to assess the status of the person's chronic medical illnesses plus the effects of any acute illnesses and injuries. Diagnosis and further investigation of these possibilities are guided by available medical history, physical exam, and results of standard blood tests.
  • The doctor will check (to rule out) common conditions that may mimic those of alcohol intoxication, such as head injuries , hypoglycemia (low blood sugar), seizure disorders, and the influence of illicit drugs (marijuana, cocaine, amphetamines, and opiates). Common opiates are heroin and codeine. In addition, psychiatric conditions, especially depression and alcohol abuse, frequently coexist. Until the alcohol wears off, it can be exceedingly difficult for the physician to separate the effects of each, and make sure the individual was not attempting suicide.
  • The doctor will look for other specific conditions. For example, if there is fever, the physician might consider meningitis, pneumonia, or some other serious infection that might be causing a change of mental status. If the blood pressure is extremely low, the physician may consider internal bleeding.
  • The doctor will be looking for evidence of chronic alcohol abuse, such as red spots on the skin (called spider angiomas), an enlarged liver, or yellow eyes or skin (jaundice, caused by damage to the liver).
