Ketamine Infusion for Complex Regional Pain Syndrome
What is it?
Ketamine is a powerful intravenous pain-relieving medication that has been used in cases of complex regional pain syndrome that are no longer responding to sympathetic blocks and oral medications.
How is it performed?
The infusion can be performed in an outpatient setting or in a hospital setting depending on the severity of the case. Monitors are attached to the patient so the physician can carefully monitor heart rate, blood pressure, and oxygen levels during the infusion. An intravenous line is placed into the patient’s vein and the infusion is started. The patient’s clinical picture dictates the does and duration of the infusion.
For patients who respond to this therapy, one can expect a decrease in the patient’s pain so that they are able to participate in physical therapy and slow bone deterioration and muscle atrophy.
How long does it take?
The dose and duration depends on the severity of the patient’s signs and symptoms, but infusions typically range from 2.5-4 hours.
