Conditioned Open Label Placebo for Postoperative Pain Management

Overview

The primary objective is to evaluate the efficacy of two Conditioned Open Label Placebos (COLP): COLP pill and COLP odor to reduce opioid intake for postoperative (thoracic and spinal surgery) pain management compared to the opioid only usual treatment (TAU).

Patients, eligible for an elective thoracic or spinal surgery, will be randomized into either standard of care, COLP\_pill or COLP\_odor. Patients in COLP groups will be asked to pair each opioid intake with an open label placebo intake (either a pill or an inhalation) for postoperative (POD) day 0 to 17. From POD 2, patients in the intervention arms will be additionally asked to take OLP alone 3 times a day. Patients will have unrestricted access to pain killers. Patients will daily assess opioid intake, pain intensity, side effects, mobility and sense of agency using a e-dairy.
