Ketamine is a medication primarily used for induction and maintenance of anesthesia. It induces dissociative anesthesia, a trance-like state providing pain relief, sedation, and amnesia. The distinguishing features of ketamine anesthesia are preserved breathing and airway reflexes, stimulated heart function with increased blood pressure, and moderate bronchodilation. At lower, sub-anesthetic doses, ketamine is a promising agent for pain and treatment-resistant depression. However, the antidepressant action of a single administration of ketamine wanes with time, and the effects of repeated use have not been sufficiently studied.
Why is Ketamine Used Medically?
- Ketamine can provide pain relief and short-term memory loss (for example, amnesia of a medical procedure).
- In surgery, it is used an induction and maintenance agent for sedation and to provide general anesthesia.
- It has also been used for pain control in burn therapy, battlefield injuries, and in children who cannot use other anesthetics due to side effects or allergies.
- Ketamine, through blocking at the N-methyl-D-aspartate (NMDA) site, has rapid action in controlling symptoms of depression and acute suicidal ideation.
- At normal doses, it is often preferred as an anesthetic in patients at risk of bronchospasm and respiratory depression.
RISK FROM SNORTING KETAMINE
Snorting Ketamine is considered relatively safe in medical settings.This is because it does not affect the protective airway. It reflexes, and it does not depress the circulatory system.However, some patients have reported disturbing sensations when awakening from ketamine anesthesia. Ketamine can cause an increase in blood pressure and intracranial pressure, or pressure in the brain. People with the following conditions cannot receive ketamine for medical purposes:
- brain swelling
- brain lesion or tumor
It is used with caution in those with:
- coronary artery disease
- increased blood pressure
- thyroid disease
- chronic alcohol addiction
- acute alcohol intoxication
- chest pain
- mental illness
These effects may be stronger in people aged over 65 years. Some people may have an allergy to the ingredients. If Patients are suffering from any of the following problems please contact your doctor if you have or contact a nearby hospital immediately.
