Sponsored by Erasme University Hospital · Observational
Ketamine has been shown to have a certain efficiency in chronic pain syndromes. However, it is still not clearly known what is its efficiency and how ketamine is used in real world patients. In this retrospective study, all patients treated with ketamine for chronic pain in our hospital will be reviewed. Patients demographics, pain syndromes as well as outcome criteria will be collected to describe the use of ketamine in pain syndromes.
The American Society of Regional Anesthesia and Pain Medicine, together with the American Academy of Pain and the American Society of Anesthesiologists published a consensus guideline in 2018 on the use of ketamine in chronic pain. A review of medical charts of all patients who received ketamine for chronic pain between january 2010 and june 2024 will be done. Demographic data, detailed pain scores, as well as description of the type of pain will be collected. Ketamine usage will be recorded for the dosage, as well as duration of the treatment. Outcome will be measured by before/after pain scores for neuropathic pain, as well as on a visual analog scale. A more global score (good-medium-no effect) will also be collected to get the patient's impression on their treatment. Concomitant pain medication will be collected.
