What’s Treatment With Ketamine Like?

Ketamine, an anesthetic that’s been used since the 1960s, was found to have unexpected and profoundly beneficial psychological effects. In general anesthesia, the goal is to put the patient to sleep. Compared to a hospital setting, patients with depression receive ketamine at a much lower dose over a shorter period of time. The infusion is controlled and can be tapered down to the patient’s needs.

Ketamine is given intravenously while the patient is on a cardiac monitor to continually assess their vital signs. Patients receiving ketamine treatment for depression often describe the feeling as floating, or an out-of-body, “loopy” experience. Short term side effects are feelings of dissociation of mind and body, disorientation, and visual hallucinations. Patients can wear an eye mask during treatment to avoid any visual disturbance. Some patients may feel a temporary numbness to hands, feet, and around the mouth. Some patients may feel nauseated toward the end of a treatment. Some patients may have an elevation in their blood pressure and heart rate. This is usually transient and resolves after the infusion is finished.

Protocol For Ketamine Treatment For Anxiety

Protocol For Ketamine Treatment For Anxiety

Pre-Treatment Evaluation

Each patient must have documentation of their diagnosis of anxiety from a qualified mental health professional. The first step is for the patient to complete diagnostics for depression, anxiety, drug abuse, and alcohol abuse before a medical screening exam. All test results are shared with the patient’s providers.

The next step is for the patient to complete a medical exam with Dr. Manno. Dr. Manno will review the patient’s medical history and discuss what to expect during the treatment experience.

Induction Treatment Phase

The induction phase of ketamine treatment for anxiety is two infusions per week for two weeks. For each treatment, the patient will receive a slow intravenous infusion starting at 0.5 mg/kg of ideal body weight. If the patient has little response to the initial treatment, the dosage will be increased up to a maximum of 0.75 mg/kg ideal body weight.

Each infusion lasts 45 minutes; after that it takes about another 45 minutes for the patient to feel back to normal. Patients must arrange to have someone take them home after treatment.

Booster Treatment Phase

Patients will need periodic infusions of ketamine to maintain the therapeutic effects. Frequency of maintenance infusions will depend upon patient response. Each patient is unique and the treatment regimen will be determined by the physician.

Post Induction Monitoring

After the two weeks of treatment have been completed, patients will take the same diagnostic tests given before the Induction Phase. We do this to compare patient responses to their baseline and measure the effectiveness of treatment. All results will be shared with the patient’s providers.

Risks and Contraindications

Patients with uncontrolled hypertension, severe heart disease, active psychosis, or in a manic phase of bipolar disorder, or are taking methamphetamines, cocaine or other stimulants should not receive ketamine treatment. Patients who are chronically taking benzodiazepines, such as xanax, valium, ativan, can have a blunted response to ketamine, and should have their mental health professional or primary physician see if they can decrease their dosage prior to treatment.
