Ketamine infusion therapy is a type of treatment used to manage chronic pain that has not responded to other forms of treatment. Ketamine is a dissociative anesthetic that can block certain pain receptors in the brain and spinal cord, making it an effective treatment for chronic pain conditions.

During a ketamine infusion, a solution of ketamine is delivered intravenously over a period of several hours, typically in an outpatient setting. The dose and duration of treatment will depend on the patient's individual needs and condition.

Ketamine infusion therapy has been used to treat a range of chronic pain conditions, including neuropathic pain, fibromyalgia, complex regional pain syndrome (CRPS), and chronic headaches. It has also been used to manage depression and other mood disorders.

The exact mechanism by which ketamine works to relieve pain is not fully understood, but it is thought to block certain receptors in the brain and spinal cord that are involved in the perception of pain. It can also help to reduce inflammation and promote the growth of new nerve cells, which may contribute to its pain-relieving effects.

Ketamine infusion therapy is generally considered safe, but as with any medical treatment, there are potential risks and side effects, such as nausea, dizziness, hallucinations, and increased blood pressure. It's important to discuss the risks and benefits of ketamine infusion therapy with your healthcare provider to determine if it's an appropriate treatment option for your specific condition and needs.
