Informed Consent for Ketamine Treatment
Informed consent is your permission to receive treatment with the knowledge of the possible consequences, possible risks and benefits. Please read the following information and ask for clarification from your provider if you have further questions. By signing this consent form, you will be acknowledging you have been advised of the risks and benefits of this treatment. 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 and concerns you had with a member of the staff, and that you consent to treatment by South Sound Health & Wellness, including any and all repeated Ketamine infusions. 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 depression. 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 an extremity 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 clinician. Under the supervision of a clinician, you will receive ketamine through a vein in your arm. The dose you receive will be determined by the clinician based on your circumstances. For the treatment of depression, patients most commonly receive between 0.5 mg to 2.0 mg of Ketamine per kilogram over approximately 40 minutes, followed by a 20 to 30-minute recovery time. For the treatment of chronic pain, patients most commonly receive between 50 to 100 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 the care of a family member or friend. You cannot drive home after the procedure and should not make important decisions or operate machinery for the rest of the day.
B. Risks of Ketamine Infusion
Off-Label Use. 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 depression, other mental health disorders, or chronic pain. Ketamine is a promising treatment for people with treatment-resistant depression. However, there is limited long-term safety and effectiveness data available for use as an antidepressant or chronic pain treatment. Accordingly, there are potential and currently unknown risks to the administration of Ketamine in repeated doses, and there is 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. Common side effects, greater than 1% and less than 10% include: 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).
Other Risks: 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 surgery 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 extremity. The risk of venipuncture may include temporary discomfort from the needle stick, bruising, 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.
Pregnancy. Receiving Ketamine or other drugs during pregnancy may be harmful to a developing fetus. It is the policy of South Sound Health & Wellness that women who are pregnant or breastfeeding or women who may be pregnant should not undergo 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. South Sound Health & Wellness offers women the option to undergo a pregnancy test in our office prior to your infusion.
For Chronic Pain: 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 clinician 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 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 clinician and additional treatment recommendations may be made based on your response to IV Ketamine treatment.
