Histotoxic hypoxia
Histotoxic Hypoxia
Histotoxic hypoxia (pronunciation: his-to-tox-ic hy-pox-ia) is a type of hypoxia that occurs when the body's cells are unable to use the oxygen delivered to them. This can be due to the cells being poisoned, such as in the case of cyanide poisoning, which inhibits the cells' ability to utilize oxygen.
Etymology
The term "histotoxic hypoxia" is derived from the Greek words "histo" meaning tissue, "toxic" meaning poison, and "hypoxia" meaning lack of oxygen. Thus, it refers to a lack of oxygen due to the poisoning of tissues.
Causes
Histotoxic hypoxia can be caused by a variety of factors, including:
- Cyanide poisoning: Cyanide inhibits the cells' ability to utilize oxygen, leading to histotoxic hypoxia.
- Alcohol intoxication: High levels of alcohol can inhibit the cells' ability to utilize oxygen.
- Certain medications: Some drugs, such as sodium nitrite, can cause histotoxic hypoxia.
Symptoms
Symptoms of histotoxic hypoxia can vary depending on the severity of the condition, but may include:
- Shortness of breath
- Confusion
- Loss of consciousness
- Seizures
Treatment
Treatment for histotoxic hypoxia typically involves addressing the underlying cause of the condition. This may involve administering antidotes for poisoning, providing supplemental oxygen, or other treatments as necessary.
