Ketamine infusions may reduce pain for some patients with treatment-resistant Complex Regional Pain Syndrome (CRPS), but the evidence is limited by small studies and varying protocols. This systematic review examined clinical studies on ketamine use for CRPS and found that while some patients experience pain relief, the quality of evidence is low, and more rigorous research is needed to confirm effectiveness and determine optimal dosing and duration of treatment.
