T36-T50: Poisoning by drugs, medicaments and biological substances

T41: Poisoning by anaesthetics and therapeutic gases

Poisoning by anaesthetics and therapeutic gases is a group of conditions that arise when a person is exposed to higher-than-recommended levels of these substances. This typically occurs due to accidental exposure or misuse. These substances, which are usually used to reduce pain and promote relaxation during medical procedures, can result in poisoning if improperly administered or ingested. Symptoms vary depending on the specific substance, but may include dizziness, confusion, shortness of breath, loss of consciousness, and in severe cases, life-threatening respiratory or cardiac distress. Disease progression can be rapid, often within minutes or hours of exposure, and primarily impacts the nervous and respiratory system. This poisoning does not spread from person to person. It is related exclusively to personal exposure to these gases or substances.
