Ketamine Infusion


What is a Ketamine Infusion?

  • Ketamine is a medication usually used in the treatment of neuropathic pain and in conditions such as complex regional pain syndrome (CRPS).
  • The aim of a ketamine infusion is to reduce the level of pain and, at the same time, increase your sensitivity to analgesia. This should reduce the amount of medications needed for pain management. 


How is Ketamine Administered?

  • Ketamine infusions are usually delivered intravenously (IV) in a hospital based setting. 
  • A plastic cannula is inserted into a vein in the arm and the Ketamine is administered via a computer operated infusion pump. 
  • Patient vital signs (blood pressure, pulse, etc) will be monitored regularly.
  • Infusion and pain level will be monitored hourly by nurses.


How Long is the Hospital Stay?

  • The average length of stay in hospital is approximately 7 days. The duration of the infusion will depend on your response to treatment.
  • You will be contacted by a nurse from HPC after discharge and an appointment given to see your doctor approximately 1-2 weeks later.


What Are the Side Effects?

The following are commonly experienced side effects:

  • Headache;
  • Light headedness;
  • Numb, tingling lip;
  • Increase in blood pressure and/or pulse;
  • Heightened emotional response;
  • Nightmares;
  • Hallucinations;
  • Nausea & vomiting.

If you become drowsy or short of breath, please let the nurse know immediately.
