I was given ketamine in the ambulance or ER after my crash. Did that cause or prevent my PTSD?

There is no way to know for one person, and the research is mixed. A retrospective 2008 study of burned service members linked ketamine during surgery to lower PTSD rates, while a small 2005 study of accident victims linked one form of ketamine given during emergency care to more posttraumatic stress symptoms. Neither was randomized. Ketamine given for pain at the scene is a different situation from a planned, monitored series of infusions for established PTSD.

Is ketamine safe, and how are infusions monitored?

In a medical setting with appropriate screening, IV ketamine has a well-established safety profile, but it is not risk-free. Common effects include temporary dissociation, nausea, and a rise in blood pressure. At Music City Ketamine, Marla Peterson, CRNA, oversees every infusion with anesthesia-level monitoring of oxygen, blood pressure, and heart rate, and a clinician is in the room. You will need someone else to drive you home.

How is ketamine different from trauma therapy, physical therapy, or pain medication?

Trauma-focused therapy remains the foundation for PTSD, and physical therapy and your medical team remain central for injuries. Ketamine acts on the NMDA glutamate receptor, which is involved in both mood and pain signaling, and research suggests it can affect mood within hours to days. It is best thought of as a possible adjunct for people who have not found enough relief, and its use for PTSD and chronic pain is off-label.

How many infusions would I need, and how long do effects last?

Most patients here begin with a series of six infusions over two to three weeks, which mirrors the schedule studied in the 2021 Feder trial. Some people notice change within the first few sessions, and some do not respond. In that trial, responses lasted a median of about four weeks after the series ended, and some patients later use occasional maintenance infusions while others do not.

Riding in a car still makes me anxious. How do I get to and from an infusion?

You will need someone else to drive you home, since you cannot drive for the rest of the day after an infusion. For many crash survivors, being a passenger is its own challenge, so we talk through it during the consultation: who drives, which route feels manageable, and what helps on the ride. You are welcome to take it slowly and plan the logistics with us before you commit to anything.

Ketamine after a car accident: PTSD, chronic pain, and what the evidence shows

When the crash is over but your body has not caught up

A car accident can take seconds. What follows can take months. Maybe you tense up every time a car drifts toward your lane, or you take the long way to avoid the interchange where it happened. Maybe you replay the sound of the impact at night, or you have stopped driving altogether. Many people are surprised by how strongly a crash stays with them, especially when they walked away and everyone told them how lucky they were.

Anyone who commutes on I-65, I-24, or I-40 around Nashville knows how ordinary a wreck can seem from the outside. From the inside, it can be one of the most frightening moments of a person's life. This article is for people in Franklin, Brentwood, and across Middle Tennessee who are still living with the aftermath of a crash, whether that looks like fear, pain, poor sleep, or all three. It is part of our Trauma & Grief series.

What research shows about PTSD after car accidents

Motor vehicle crashes are among the most common traumatic events in daily life, and the research on what follows them is fairly consistent. A 1999 study in the American Journal of Psychiatry by Ursano and colleagues followed 122 people injured in motor vehicle accidents for a year, alongside a comparison group with minor injuries from other causes. One month after the crash, 34.4% of the accident survivors met criteria for PTSD, compared with 2.4% of the comparison group. The rate was 25.2% at three months and 18.2% at six months, and it stayed elevated about nine months out.

The same study found that people with a history of PTSD before the crash had roughly eight times the odds of developing PTSD one month afterward. That matters, because it means a crash can land on top of older trauma. If a wreck has stirred up memories of something earlier, you are not overreacting; that pattern is well described. Our article on trauma anniversary reactions explains why the date of a crash can bring symptoms back, and trauma nightmares covers the sleep side of the picture.

Trauma and pain after a crash often travel together

Crash survivors rarely deal with fear alone. A 2008 review in Spine by Carroll and colleagues, part of the Bone and Joint Decade 2000–2010 Task Force on Neck Pain, concluded that about half of people with whiplash-associated disorders still report neck pain one year after their injury. Back pain, headaches, and nerve pain can linger too, and a head injury can add its own complications, which we cover in ketamine after traumatic brain injury.

Pain and PTSD tend to feed each other. Pain can serve as a constant physical reminder of the crash, and the hypervigilance of PTSD can make pain feel louder. Researchers describe a related process called central sensitization, in which the nervous system becomes more reactive to pain signals over time; we explain it in ketamine and central sensitization. For a deeper look at this overlap, see ketamine for PTSD and chronic pain.

How ketamine may help when fear and pain get stuck

Ketamine blocks the NMDA receptor, a gateway for the neurotransmitter glutamate. In the brain, research suggests this sets off a brief surge of signaling through a different receptor, AMPA, followed by the release of growth factors such as BDNF and the formation of new synaptic connections. The working hypothesis is that this opens a window of greater neuroplasticity, when fear memories and rigid patterns may be easier to loosen with therapy.

NMDA receptors also play a central role in how the spinal cord and brain amplify pain, which is one reason anesthesia teams have used ketamine for decades to manage difficult pain. That dual role, in mood circuits and in pain pathways, is why ketamine is being studied for people whose trauma and pain overlap. It is a reason for interest, not proof that it will work for any one person.

What the clinical data shows, and its limits

Ketamine is FDA-approved as an anesthetic; its use for PTSD, depression, and chronic pain is off-label. Esketamine (Spravato), a related nasal spray, is FDA-approved for treatment-resistant depression. No trial has tested ketamine infusions in crash survivors as a group, so the relevant evidence comes from two directions:

Ketamine given around the time of injury. A retrospective 2008 study in the Journal of Trauma by McGhee and colleagues found that burned service members who received ketamine during surgery had a lower rate of PTSD (27%) than those who did not (46%). But a small 2005 study in Psychopharmacology by Schönenberg and colleagues, in 56 moderately injured accident victims, found that those given one form of ketamine, (S)-ketamine, during emergency care had more severe and longer-lasting posttraumatic stress symptoms than those given opioids. Neither study was randomized, and together they show that ketamine at the scene is not a proven way to prevent PTSD.
Ketamine for established PTSD. A 2021 trial in the American Journal of Psychiatry by Feder and colleagues gave 30 adults with chronic PTSD six infusions over two weeks. Sixty-seven percent of the ketamine group met the response threshold, compared with 20% on midazolam, and responses lasted a median of about four weeks. A larger 2022 trial in Neuropsychopharmacology by Abdallah and colleagues, in 158 veterans and service members, did not find a difference from placebo on PTSD symptoms, although the standard dose improved depression.

The honest read is that the evidence is promising but mixed, and the trials were small. Ketamine helps some people with PTSD and not others. Our overview of ketamine for PTSD walks through the broader research, the PTSD page gathers related reading, and our chronic pain page and article on ketamine for chronic pain cover the pain research.

Trauma-focused therapy remains the foundation for PTSD, and physical therapy and your medical team remain central for injuries. For trauma presentations, we generally recommend having a licensed therapist in place before starting infusions; our guide to finding an integration therapist in Tennessee is a practical starting point. Never start, stop, or change a pain or psychiatric medication on your own because of anything you read here; talk with your prescribing provider first.

What to expect at Music City Ketamine

It starts with a consultation, which is simply a conversation. You never have to describe the crash in detail, and our approach to trauma-informed ketamine care explains why. We review your medical history, injuries, current medications, and blood pressure, and we screen for conditions where ketamine is not appropriate. If you are still under active orthopedic, neurological, or pain care, we coordinate with your existing clinicians rather than working around them.

If ketamine looks like a reasonable fit, most patients begin with six infusions over two to three weeks. Each infusion is CRNA-led: Marla Peterson, CRNA, oversees every infusion with anesthesia-level monitoring of oxygen saturation, blood pressure, and heart rate, and a clinician is in the room. Learn more about what a CRNA is. Some people worry that ketamine will bring the crash rushing back; our article on whether ketamine can cause flashbacks addresses that directly.

You cannot drive after an infusion, and our guide to driving and ketamine explains why. For crash survivors, being a passenger can be hard in its own way, so we talk through who drives you, what route feels manageable, and what helps on the way home. Our two Old English Sheepdogs, Walter White and Wilma, are part of the welcome, and they are entirely optional.

Honest expectations

Ketamine does not repair a damaged disc, heal a fracture, or settle an insurance claim. It does not erase the memory of the crash, and it is not a substitute for trauma therapy, physical therapy, or medical follow-up. What some people describe instead is that the constant alarm quiets enough for therapy, rehab, and getting back behind the wheel to feel possible. Others notice little change, and some do not respond at all. Benefits from an initial series may fade over weeks.

Because these uses are off-label, health insurance generally does not cover them, and auto insurance coverage varies; ask your own carrier or attorney rather than relying on us. Sessions are $475 each. If you are in crisis or thinking about suicide, call or text 988, the Suicide & Crisis Lifeline, or call 911.
