Ketamine infusion therapy is an innovative method used to treat chronic pain, treatment-resistant depression, and certain anxiety disorders. This treatment involves the controlled intravenous (IV) administration of ketamine. Ketamine is a fast-acting anesthetic and analgesic that alleviates pain and depression symptoms by affecting certain chemicals in the brain. The treatment session typically lasts between 40 minutes and several hours, and patients are closely monitored during the procedure. While ketamine infusion therapy can provide rapid and significant relief, potential side effects may include hallucinations, dizziness, and nausea. For this reason, it is important to undergo a detailed evaluation with a healthcare professional both before and after treatment.
Ketamine infusion therapy is a method used to treat chronic pain, depression, and certain psychiatric disorders. This treatment involves the slow administration of the drug ketamine intravenously (IV). Ketamine is a drug with anesthetic and analgesic properties that can alleviate symptoms of pain and depression by affecting brain chemicals.
For Which Conditions Is Ketamine Infusion Therapy Used?
Ketamine infusion therapy, along with medication and psychotherapy, is one of the first-line treatment options for depression. Among biological treatments, the group of drugs known as “antidepressants” plays a significant role in treatment. However, in 30–35% of patients, current medication treatments are insufficient and may cause serious side effects. This situation has led physicians and scientists to seek new treatment options
.
Ketamine Infusion Therapy (KIT) was discovered as a result of this search. Following promising results from scientific research, it has begun to be used in the treatment of treatment-resistant depression, particularly in countries such as the U.S. and Canada. Through the collaborative efforts of psychiatrists and anesthesiologists, internationally recognized protocols for the clinical use of ketamine infusion have been established, the clinical diagnoses for which it can be used have been specified, and it has been made available to thousands of patients in a growing number of Ketamine Treatment Units.
It is used in the treatment of psychiatric disorders such as major depression, bipolar disorder—depressive episode, and postpartum depression, as well as Post-Traumatic Stress Disorder (PTSD), Obsessive-Compulsive Disorder (OCD), anxiety disorders, and fibromyalgia.
The Ketamine Infusion Treatment Process
The ketamine infusion treatment process consists of several stages, each of which is crucial for the patient’s safety and the effectiveness of the treatment. Here are the steps of the ketamine infusion treatment process:
1
. Evaluation and Consultation
The treatment process begins with a detailed evaluation of the patient’s medical history and current condition. During this stage, the patient’s symptoms—such as depression, anxiety, or chronic pain—as well as his history of previous treatments and other health issues are taken into account. Additionally, the patient’s suitability for ketamine treatment is determined, and he is provided with information about the treatment.
2. Preparation
Prior to treatment, the patient is prepared both physically and psychologically. Precautions are taken to ensure the patient arrives properly prepared for treatment, including confirming whether he is on an empty stomach and providing information about any medications he is taking. The patient is informed about the treatment process, potential side effects, and what to expect.
3. Infusion
Ketamine infusion therapy is typically administered in a specialized clinic or hospital. The ketamine medication is administered intravenously to the patient at the prescribed dose and for the specified duration. The infusion duration generally ranges from 40 minutes to several hours. Throughout this time, the patient’s vital signs (heart rate, blood pressure, oxygen level) are closely monitored.
4. Observation and Monitoring
Patients are closely monitored during and after treatment. Due to ketamine’s rapid effects and potential side effects, the patient may need to be kept under observation for a period of time following treatment. During this phase, immediate intervention is provided if the patient exhibits any adverse side effects.
5. Next Steps and Follow-Up
After treatment, an assessment is made to determine whether the patient’s symptoms have improved and how long the effects of the treatment last. Generally, the effects of ketamine infusion therapy can last for several weeks, and some patients may require repeated infusion sessions. The patient’s condition is monitored through post-treatment follow-up appointments,
and adjustments are made to the treatment plan as needed.
Ketamine infusion therapy is a promising method for managing conditions such as treatment-resistant depression, anxiety disorders, and chronic pain. However, it is important that this treatment be administered under the supervision of a healthcare professional and under appropriate medical conditions.
How Did Ketamine Come to Be Used in Treatment?
Ketamine was initially developed as an anesthetic in the 1960s and began to be widely used in medical procedures. It was particularly favored for its ability to provide rapid and effective anesthesia during surgical operations and on the battlefield. However, as the effects of ketamine on specific neurotransmitter systems in the brain were discovered, research focused increasingly on its potential applications in psychiatry and pain management. In the early 2000s, it was discovered that ketamine, when used in low doses, produced rapid and potent antidepressant effects. This finding has led to the use of ketamine as a potential treatment option for treatment-resistant conditions such as treatment-resistant depression, anxiety disorders, and chronic pain. Clinical studies and hospital practices have contributed to the adoption of ketamine as a safe and effective treatment method, and today, many healthcare centers have begun to implement ketamine infusion therapy.
What Are the Outcomes of Ketamine Infusion Therapy?
The results of ketamine infusion therapy are generally positive, providing rapid and significant improvements, particularly in conditions such as treatment-resistant depression, anxiety disorders, and chronic pain. Patients typically report improvements in mood, energy levels, and overall quality of life shortly after the first infusion. Side effects that may occur during and after treatment include nausea, dizziness, and hallucinations; however, these side effects are usually temporary. Ketamine infusion therapy is also effective for pain management, providing a significant reduction in pain levels for patients who do not respond to traditional methods. However, research into its long-term effects is ongoing, and the success of the treatment depends on individual patient characteristics.

Following treatment, an assessment is made to determine whether the patient’s symptoms have improved, and the effects of the treatment are monitored. Generally, the effects of ketamine infusion therapy can last for several weeks, and repeat sessions may be necessary for some patients.
How Is the Medication Dose Adjusted in Ketamine Treatment?
In ketamine treatment, the amount of medication administered to the patient is carefully adjusted according to the patient’s individual characteristics and needs. During this process, the patient’s medical history, current health status, and response to treatment are taken into account. The patient’s vital signs are closely monitored before and during treatment to determine the most appropriate and safe dose.
Is There a Protocol for Ketamine Infusion Therapy?
There is a specific international protocol for the use of this medication. Ketamine is normally an anesthetic agent. In this treatment, a dose much lower than that used in anesthesia is administered. The patient does not fall asleep during the procedure. A very low dose is administered intravenously in a saline solution over a 45-minute period. Ketamine has a rapid antidepressant effect. Many studies indicate that immediately after the first treatment, patients experience an improvement in their emotional state and mood, a reduction in suicidal tendencies, and an overall sense of well-being.
For Which Patients Is Ketamine Infusion Therapy Suitable?
Ketamine infusion therapy is particularly suitable for patients with treatment-resistant depression, anxiety disorders, post-traumatic stress disorder (PTSD), and chronic pain who have not responded to traditional treatments. This treatment may be an effective option for patients who have not achieved sufficient improvement with other treatment methods or who are seeking rapid relief. However, it is important to conduct a comprehensive medical evaluation to determine whether it is appropriate for each individual patient.
