Informed Consent to Ketamine Treatment
Before you decide to take part in this procedure, it is important for you to know why it is being done and what it will involve. This includes any potential risks to you, as well as any potential benefits you might receive and alternatives to Ketamine Therapy.
Please closely read the information below closely and ask one of the clinical staff, if there is anything that is not clear or if you would like more information. If you do decide to take part, your signature on this consent form will show that you received all of the information below, that you were able to discuss any questions or concerns with a member of the staff. You understand ny signing below, that you consent to treatment by Virginia Infusion Therapies, including any and all repeated Ketamine infusions with Virginia Infusion Therapies.
Ketamine is widely used in emergency departments and operating rooms, for the purposes of surgical sedation. Ketamine has not been approved by the Food and Drug Administration (FDA) to treat depressive conditions or chronic pain. This is not a research study, but is rather a clinical procedure. This procedure is not being monitored by the Institutional Review Board (IRB) or FDA.
An intravenous line (IV) will be started in your arm, so you can receive Ketamine. Your blood pressure, heart rate, and oxygen saturation will all be monitored throughout the infusion under the supervision of a physician.
Under the supervision of a physician, you will receive ketamine through a vein in your arm. The dose you will receive will be determined by the physician based on your diagnosis, experience with Ketamine and response to treatments. For the treatment of depression and depressive conditions, patients most commonly receive between 0.5 mg to 2.0 mg of Ketamine per kilogram over 40-60 minutes, followed by a 30-45 minute recovery time (This is only an estimate and will be individually tailored to each client). For the treatment of chronic pain and related conditions, patients most commonly receive between 50 to 150 mg of Ketamine per hour over four hours, followed by a 1 to 2 hour recovery time.
You will be monitored and then released to return home. You must arrange for transportation home from your appointment. You cannot drive home after the procedure and should not make important decisions, drive or operate machinery for the rest of the day.
B. Risks of Ketamine Infusion
Before a drug can be approved, a company must submit clinical data and other information to the Food and Drug Administration (“FDA”) for review. The company must show that the drug is safe and effective for its intended uses. “Safe” does not mean that the drug has no side effects. Instead, it means the FDA has determined the benefits of using the drug for a particular use outweigh the potential risks. Once a drug has been approved by the FDA for one purpose, healthcare providers may generally prescribe that drug for other purposes, when they judge that it is medically appropriate for their patient. The practice of prescribing a drug for a purpose other than that for which it is approved is known as “off-label” use.
Ketamine has not been approved by the FDA to treat chronic pain disorders or depressive disorders. Intravenous (IV) Ketamine Infusion for the treatment of chronic pain disorders or depressive disorders is an off-label use of this drug. There is limited long-term safety and effectiveness data available for use as an antidepressant or for chronic pain. Accordingly, there are potential and currently unknown risks to the administration of Ketamine in repeated doses, and insufficient evidence of the safety of Ketamine in repeated doses.
Any procedure has possible risks and discomforts. The procedure may cause all, some, or none of the risks or side effects listed. Rare, unknown, or unforeseeable risks may also occur. It is important that you are truthful and forthcoming with Virginia Infusion Therapies, about your medical history and past or present drug usage, as it may affect your response and safety with IV Ketamine treatment.
Common side effects, greater than 1% and less than 10% include:
- Laryngospasm (1-2%), hallucinations, nausea and vomiting, increased saliva production, dizziness, blurred vision, increased heart rate and blood pressure during the infusion, out of body experience during the infusion, change in motor skills.
- These symptoms are usually mild and often dissipate within hours after the infusion is stopped.
Uncommon side effects, greater than 0.1% and less than 1% include:
- Rash, double vision, pain and redness in the injection site, increased pressure in the eye, jerky arm movements resembling a seizure.
Rare side effects, greater than 0.01% and less than 0.1% include:
- Allergic reaction, irregular or slow heart rate, arrhythmia, low blood pressure, cystitis of the bladder (bladder inflammation, ulcers, and fibrosis).
Ketamine can cause various symptoms including, but not limited to flashbacks, hallucinations, feelings of unhappiness, restlessness, anxiety, insomnia and disorientation. Individuals with a history of drug misuse or dependence can develop a dependency on ketamine. The amount of ketamine used in treatment of depression is much lower than the amount used for surgical sedation, but there is limited information about long-term safety and effectiveness and risk for addiction for repeated doses of ketamine.
With administration of any medication, including IV Ketamine, there is a risk of dosing error or unknown drug interactions which may require medical intervention including, but not limited to intubation (placement of a breathing tube) and/or hospitalization. These risks can be serious and possibly fatal. To reduce these risks, it is very important that you disclose all medications, supplements, and/or other drugs that you are taking.
To administer the Ketamine, an IV will need to be inserted into your arm. The risk of venipuncture may include temporary discomfort from the needle stick, bruising, blood clots, bleeding, nerve damage, pain, infection and fainting.
Ketamine may not alleviate your symptoms. Ketamine may only temporarily relieve symptoms and may require additional future infusions. Ketamine therapy does not work for everyone and may need to be discontinued due to lack of response to medications, adverse side effects, non-compliance with instructions or for any other reason your physician feels necessary.
Receiving Ketamine or other drugs during pregnancy may be harmful to a developing fetus. It is the policy of Virginia Infusion Therapies that women who are pregnant or breastfeeding or women who may be pregnant should not receive IV Ketamine Infusion. If you are pregnant or breastfeeding, or if there is any chance that you may be pregnant, you should inform clinical staff immediately, before treatment. Virginia Infusion Therapies offers women the option to undergo a pregnancy test in our office prior to your infusion.
There are two small studies that have examined whether patients with bipolar depression improve with ketamine treatment. These studies suggest that ketamine may be helpful to these patients. One area of concern regarding the treatment of bipolar patients with ketamine is whether there is a potential to induce mania or hypomania in bipolar patients. This may be similar to the risk in almost all of our current antidepressant treatments. Again, little research has been done, so it is difficult to quantify the size of the risk of mania in a bipolar patient receiving ketamine.
For Chronic Pain Disorders:
Ketamine has been associated with a decrease in chronic pain symptoms, with patients reporting varying lengths and levels of pain-relief. It is difficult to predict how any single person will respond to ketamine infusion therapy. Your response to treatment will be monitored by your physician and additional treatment recommendations may be made, based on your response to IV Ketamine treatment.
For Depression and Other Mental Health Disorders:
Ketamine has been associated with a decrease in depression and anxiety symptoms with patients reporting varying lengths and levels of relief. It is difficult to predict how any single person will respond to ketamine infusion therapy. Your response to treatment will be monitored by your physician and additional treatment recommendations may be made based on your response to IV Ketamine treatment. Please note if you have thoughts of hurting yourself or others and feel acutely suicidal, you should seek medical/psychiatric help Immediately. Please call 911 or the suicide hotline 1-800-273-8255. These temporary situations will not necessarily prevent you from getting help with IV Ketamine at a later time.
