Treatment Process
Explore the step-by-step process of ketamine infusion therapy.
Before starting treatment
Your psychiatric provider must determine that ketamine is an appropriate treatment for you. They will then order the ketamine nurse to administer the prescription. The first infusion appointment will take a little longer than subsequent treatments, but generally, you should plan for 90 min for the first treatment and 60 min for subsequent treatments. You will initially meet with the ketamine nurse and review the risks and benefits of the procedure to obtain your consent prior to starting the treatment. This gives you and your family the opportunity to ask any last-minute questions you may have before treatment begins.
Preparing for the infusion
You should wear comfortable clothing that allows easy access to your forearms for IV placement. Unless otherwise instructed, you should take your medications as you normally would but avoid taking any new medications or as needed medications for 8 hours prior to the procedure.
The procedure setting
You will be in a quiet, relaxing, private or semi-private space with a comfortable recliner and soft lighting. There may be space in the room for a friend or family member to stay with you for support. You can talk normally, but you shouldn't expect to have much meaningful conversation since you will find that you'll want a calm and quiet environment. We provide some optional items to help you stay relaxed and comfortable such as a soft blanket, fluffy pillows, water to sip, and noise canceling headphones to block ambient sound and listen to music during the treatment.
Starting the IV (for IV ketamine only)
Our specialized ketamine nurses are very experienced with IV placement and will place the IV catheter using a small-gauge needle as painlessly as possible to use for the infusion. Prior to starting the Ketamine drip, a medication such as atropine (or glycopyrrolate) is administered to safely and effectively prevent some of the possible side effects of Ketamine including excessive salivation and nausea.
During the treatment
A few minutes after the treatment begins, you will likely start to experience a peaceful and relaxing state that feels disconnected from your body and the world around you. This is a state of dissociation that may include perceptual disturbances, which most people have a difficult time describing. Some patients describe difficulty perceiving the passage of time, some see colors, some describe interesting feelings in their bodies like tingling, numbness, or increased size of limbs.
Getting the most out of treatment
The level of dissociation is not always the same from one treatment to another and the benefit of the treatment is not dependent on having an intense experience. Many factors play a role in the patient's subjective experience during the treatment, which depending on the patient, may include feeling anxious, being sleep deprived, being in pain, and the level of comfort with the procedure. We strongly advise patients to approach Ketamine treatments with the outcome in mind, especially if the temporary feeling of dissociation may make you feel anxious or uncomfortable.
Assuring safety
The nurse will monitor your vital signs during the treatment including heart rate, blood pressure, and oxygen saturation, and following the doctor's orders for your treatment, the nurse may adjust the Ketamine drip rate (for IV treatments) or administer comfort medications to optimize your response and prevent side effects. The doctor can be reached at a moment's notice if needed.
Dosing the treatment
We will start with a low-dose , typically at 0.5 mg/kg, consistent with accepted protocols that have been developed and researched since the early 2000’s. In order to find the most effective dose, we recommend always starting with IV treatments so we have the ability to speed up or slow down the infusion rate and/or raise or lower the dose. These adjustments can be made during an infusion (infusion rate) or adjusted for subsequent treatments (infusion rate and dose). You may experience different feelings and sensations from one treatment to the next regardless of whether any changes were made, and this is all very normal. There is no typical sensation a patient should experience in order to have a good effect. Although we may increase a patient's dose, unlike most medication treatments, a higher dose of Ketamine is not necessarily more effective, which is why the benefits of Ketamine for mood were not apparent over decades of using high doses for anesthesia.
Following treatment
The nurse will remove the IV catheter after the treatment and allow you to fully recover before you leave. You will need someone to drive you home because although you may feel fine, your reflexes will be slowed and equilibrium may be slightly off, so you will not be safe to drive, care for children, or make important decisions until you've had a full night's sleep to reset. We also have patients who choose to take a cab or an Uber; although this is not preferred, since we feel it would be best to travel with someone you know and trust. The medication will rapidly leave your system as soon as the treatment is completed, so you will quickly feel the effects of ketamine dissipate. However, lingering side effects such as slowed reflexes and poor equilibrium may persist until you have had a night of sleep, which is why you need a ride home.
