Official title
A Prospective Randomized Controlled Pilot Study Nitrous Oxide for the Treatment of Complex Regional Pain Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Patients will then be randomized via a web-based randomization system Redcap Allocation will be stratified based on the presence of a pre-existing spinal cord stimulator to either the nitrous oxide study group or the oxygen control group. The nitrous oxide group will receive 50% nitrous oxide mixed with 50% oxygen, and the control group will receive 50% oxygen (oxygen plus air mixture). Both groups will undergo inhalation therapy for a duration of 2 hours via an FDA-approved mask breathing circuit. Vital signs (blood pressure, respiratory rate, heart rate) will be monitored every 30 minutes. Pulse oximetry monitoring will be continuous. Patients will be monitored for side effects including nausea, vomiting, desaturation, sedation, respiratory depression, and dizziness. Patients and other involved providers will be blinded to the treatment type.
