What “too intense” usually means in practice
When patients tell us a ketamine session was too intense, they almost always mean one of a few specific things. The dissociation went further than they expected and they briefly lost track of where their body was. A wave of grief or fear surfaced and would not be argued with. A piece of imagery—a memory, a face, a place—arrived more vividly than waking life and stayed for several minutes. Time stretched. The room receded.
None of those are signs that something has gone wrong. They are common features of the medicine working. But they can be alarming if you walked in expecting a quiet, hazy float and instead encountered something more layered. Patients who arrive with a clearer picture of what is possible tend to do better. Understanding dissociation before the first session helps the experience feel like territory rather than territory you are lost in.
It is also worth saying plainly: ketamine is FDA-approved as an anesthetic, and its use for depression, PTSD, anxiety, and chronic pain is off-label. The intensity profile you may encounter has been studied for decades, but you are entering a treatment whose psychiatric applications are still being defined. We try to be honest about that frame on the way in.
How the CRNA reads the room in real time
Marla Peterson, CRNA, oversees every infusion at Music City Ketamine and provides anesthesia-level monitoring throughout the session. That phrase carries specific meaning: continuous pulse oximetry, blood pressure cycling, heart rate, respiratory observation, and a clinician trained to act on those numbers. The CRNA is in the room and on-site for the duration of your infusion.
What the CRNA is doing is not psychotherapy. We want to be clear about this distinction because it matters for your expectations. The clinical role during the infusion is to keep you physiologically safe, to read for signs of distress versus signs of productive processing, and to coach you through grounding when you ask for it or when your body language says you need it. Deep emotional processing and meaning-making happen with an integration therapist after the fact, not at the bedside during the medicine.
What does the CRNA actually watch? Vitals, of course—but also breathing rhythm, facial tension, hand position, restless leg movement, the sound of your voice if you speak. Patients also signal in their own ways, and we encourage you to do so. A raised hand. A word. “Slow it down.” “I need a minute.” If you are unsure whether to speak up, the rule is simple: speak up. Here is more on what Marla does during a session.
Grounding techniques that work mid-session
If a session starts to feel like more than you can hold, there are a small number of techniques that consistently help. None of them require you to think clearly, which matters, because thinking clearly is the part that is offline.
- Open your eyes briefly. Looking at the room for two or three seconds reminds your nervous system where it is. You can close them again immediately. This single move resolves a surprising number of overwhelm spikes.
- Slow your breath, lengthen the exhale. A four-count in, six-count out, repeated three or four times. The longer exhale activates parasympathetic tone and brings the body back below threshold.
- Press your hands into the chair. Physical pressure through the palms or feet gives the brain a clean proprioceptive signal that you have a body and the body is here.
- Say one word out loud. Your name. The word “here.” The CRNA's name. Speech reactivates frontal-cortex circuits and pulls you partway back without ending the experience.
- Ask the CRNA to slow the drip. This is always a real option, not a last resort. Bringing the dose down a notch usually softens the curve within a minute or two.
- Change the music. The right playlist can hold you; the wrong one can amplify whatever is already loud. We can swap tracks mid-session.
Patients sometimes worry that using a grounding technique will “ruin” the session or undo the medicine's work. The opposite is closer to true. Grounding gives you the capacity to stay with the material rather than fight it, and staying with the material is where the benefit comes from. More on managing in-session anxiety here.
When we slow or pause the infusion—and when we don't
We will adjust the infusion when there is a clinical reason: blood pressure or heart rate moving outside our parameters, signs of nausea or vomiting risk, respiratory changes, or a patient who is asking us to. We will also slow the rate when a patient is clearly distressed in a way that grounding alone is not resolving. The FDA-required REMS monitoring window for Spravato (esketamine) was built around exactly this principle—the prescribing information specifies observation until transient psychoactive effects resolve before discharge. We apply the same logic to IV ketamine.
What we generally will not do is stop the infusion the moment a patient encounters something hard. A wave of grief at minute fifteen is not, by itself, a reason to abort. Dore and colleagues, in a 2019 paper in the Journal of Psychoactive Drugs reporting outcomes from ketamine-assisted psychotherapy practice, emphasized that clinician presence and integration are what convert intense experiences into clinical benefit. Ending the session prematurely tends to leave the patient with the difficulty and without the integration. That is a worse outcome than working through the moment with support.
The judgment call is real, and we make it together. If you tell us you genuinely need to stop, we stop. If you tell us you are scared but want to continue with adjustments, we adjust. The conversation is collaborative.
Why intensity often correlates with breakthrough
Bremner and colleagues, in their 1998 paper in the Journal of Traumatic Stress, validated the Clinician-Administered Dissociative States Scale (CADSS), which captures derealization, depersonalization, and amnesia in real time. CADSS scores reliably rise and fall during ketamine sessions. Many patients reach scores that, on paper, look high—and those same patients often report meaningful clinical change afterward.
The relationship between dissociative intensity and outcome is not perfectly clean in the research literature, but the broad pattern is consistent: the patients who go nowhere during sessions also tend to benefit less. The patients who encounter real material and stay with it—sometimes uncomfortably—are often the ones who report the most durable shifts. This is not an argument for chasing intensity. It is an argument for not panicking when intensity arrives.
The same logic shows up in why crying during a ketamine session is not a problem and is often a feature.
Dose recalibration for the next session
If a session was too intense, the most concrete thing we can change is the dose, the ramp, or both. After your session, we sit down and review what happened: when the intensity peaked, what it felt like, what helped, what did not. That conversation is data for the next protocol.
For some patients, we lower the next dose by 10 to 20 percent. For others, we keep the dose and slow the ramp—the rate at which the infusion comes up to its peak—so the body has more time to acclimate. For others, the issue was not the medicine at all but the surrounding inputs: the music, the lighting, an unsettled mental state walking in. Those are also adjustable.
The point worth absorbing: the first session is not the protocol. It is information for the protocol. Many patients describe their second or third session as more workable, even when the first one was hard, because we tuned the dose to what their nervous system actually showed us. Our approach is built around this iterative recalibration rather than a fixed recipe.
Integration after a hard session is non-negotiable
If a session brought up real material—grief, fear, a memory, a piece of imagery that stayed with you—integration is not optional. Integration is the conversation, journaling, therapy, or quiet processing that turns the experience into something usable. Without it, an intense session can sit unresolved for days or weeks and feel like a disturbance rather than a treatment.
We can connect you with an integration therapist if you do not have one. Some patients use our network; some bring their own; some combine ketamine with other modalities as part of a broader plan. What matters is that you are not metabolizing a hard session alone. Dore and colleagues' 2019 outcome data, again, reinforces this point: integration is part of why the treatment works, not an add-on.
When intensity is a sign to step back rather than push forward
Most intense sessions are workable. Some are not, and we want to name that honestly. If a session leaves you destabilized for more than a few days, if it triggers symptoms you have not had in years, if it produces a flashback profile you cannot integrate with support, those are reasons to pause and reassess rather than schedule the next infusion.
We have declined to continue treatment with patients when we believed continuing was not in their interest. That decision is rare, but it exists. Ketamine is a powerful tool; it is not the right tool for every person at every moment, and pushing forward against clear signals is not what good care looks like. We would rather have an honest conversation about pausing than book another session because the calendar says so. Research suggests ketamine helps many patients with treatment-resistant conditions, but evidence does not support pretending it helps everyone.
