ICD-10: T40.903

The ICD-10 code T40.903 refers to "Poisoning by unspecified psychodysleptics [hallucinogens], assault." This code is part of the broader classification for poisoning and drug-related conditions, specifically focusing on substances that can alter perception, mood, and cognitive processes.

Clinical Description

Definition of Psychodysleptics

Psychodysleptics, commonly known as hallucinogens, are substances that can induce alterations in perception, mood, and cognitive processes. These substances can lead to experiences such as hallucinations, altered states of consciousness, and significant changes in thought patterns. Common examples include LSD (lysergic acid diethylamide), psilocybin (found in certain mushrooms), and mescaline.

Poisoning by Hallucinogens

Poisoning from hallucinogens can occur through various routes of administration, including ingestion, inhalation, or injection. Symptoms of poisoning may include:

• Visual and auditory hallucinations: Distorted perceptions of reality.
• Altered sense of time and space: Individuals may feel time is moving slower or faster than usual.
• Mood disturbances: This can range from euphoria to severe anxiety or paranoia.
• Physical symptoms: These may include increased heart rate, nausea, and sweating.

Assault Context

The specification of "assault" in the code indicates that the poisoning occurred as a result of an assaultive act. This could involve a scenario where an individual is intentionally administered a hallucinogenic substance against their will, leading to acute poisoning. Such cases may require careful documentation and consideration in both clinical and legal contexts.

Clinical Management

Management of poisoning by hallucinogens typically involves:

1. Assessment: A thorough evaluation of the patient's vital signs, mental status, and any physical symptoms.
2. Supportive Care: This may include ensuring a safe environment, monitoring for severe agitation or psychosis, and providing reassurance.
3. Symptomatic Treatment: Benzodiazepines may be used to manage severe anxiety or agitation, while antipsychotics can be considered for persistent psychotic symptoms.
4. Hydration and Monitoring: Ensuring the patient is hydrated and monitoring for any complications.
