Since July 2021, we have been offering chronic pain treatments in Gatineau at our private clinic at 430 Boulevard de l'Hôpital. Among the treatments offered, we provide therapeutic infusions for the control of chronic pain, namely lidocaine, ketamine, and pamidronate. We noticed that some patients mentioned being improved in terms of mood. Knowing that ketamine infusion is a treatment for depressive states that do not respond to conventional treatment, we decided to offer the service.

Clinic context: We have been an anesthesiologist for 22 years and continue to practice anesthesia in a private clinic in Montreal. Our ACLS certification is valid and renewed every 2 years. On site, I am assisted by a nurse who, together with myself, closely monitor the patient during the procedure. On site, we have a defibrillator and resuscitation medications that are available and ready to be used.

Limit of the service: we provide the medical procedure with safety and supervision, we do not carry out the psychiatric follow-up of the patient, this follow-up must be provided by the referring doctor.
