Auriculotherapy for Surgical Pain

Once patient has signed the Informed Consent to participate in this trial, demographic information and medical history will be collected from each participant on the day of surgery. Research staff will record this information from the medical chart. The Medical Outcomes Study Questionnaire 12-Item Short Form Health Survey (SF-12) will also be administered at this time to obtain baseline value. Randomization will occur by assigning the participant a subject ID number, and this ID number will correspond to a treatment allocation based on a pre-designed randomization schema. This treatment allocation (intervention/control) will be contained in a sealed, opaque, envelope with the subject ID number that is designated on envelope. The master randomization list will be created and held by an independent data monitor who will both create and hold the master randomization list. Study coordinators, Co-Is and subjects will be blinded. Only the research staff completing the treatment will be unblinded. Once the patient is randomized to a treatment group by research staff, Auriculotherapy will be performed by certified research staff using a cryoauriculopuncture in the post-anesthesia recovery room, either with nitrogen gas (intervention group), or an empty cryoauriculopunture with no gas (control group). After proper disinfection of the designated ear, the treatment consists of the stimulation of 9 ear points on the ipsilateral ear. These points include:-Ω2 (the master point for the mesoderm), the shoulder point, 6 points involved with the pain pathway (the stellar ganglion, the sensory and motor C7 branches, the sensory master point (MSP), the reticular master point (RMP) and the point corresponding to the Thalamus). Finally, the stimulation of the ACTH point completes the treatment. The total time required to complete auriulotherapy treatment is approximately 10 minutes. The enrolled subject will also receive a pre-operative interscalene block as per standard of care. The patient will receive standard of care treatment for surgery, post-operative pain management, and physical therapy. After surgery, the subject will be assessed at time of hospital discharge to review how to complete the subject diary, administer pain satisfaction questionnaire (0-6) and obtain NRS pain at rest and with movement scores (0-10). When the patient is discharged from the hospital, the subject will be asked to take home and complete a subject diary where they will record their total narcotic/pain medication consumption, pain satisfaction score (0-6), and NRS pain score (0-10), and adverse events daily for first 5 days post-discharge. The subject will be instructed to complete the diary just before bedtime on these post-op days. The patient will be contacted via telephone on Day 5 post-operatively as a reminder to return pain diary. On post-operative Day 14, 30, 60 and 90 telephone calls, functional recovery will be measured using the Medical Outcomes Study Questionnaire 12-Item Short Form Health Survey (SF-12). The subject will also be asked to assess their overall patient satisfaction at the Day 90 call, on a scale of 0 (least satisfaction) to 10 (most satisfaction). Analgesic efficacy in both groups will also be evaluated by the amount of total narcotic consumption (measured with oral morphine equivalent doses of analgesics used to provide pain relief). Secondary outcome measures will include pain at rest and with movement, total non-narcotic pain medication consumption for the first 5-days post-discharge, time to readiness for discharge from PACU, time to hospital discharge, readmission to the hospital because of pain related issues, incidence of postoperative complications, overall patient satisfaction, patient satisfaction relating to pain management and functional recovery. Functional recovery will be measured using the Medical Outcomes Study Questionnaire 12-Item Short Form Health Survey (SF-12). Since, starting the study, the secondary outcome measure of "Change in post-operative opioid consumption in opioid naïve subjects undergoing rotator cuff surgery" has been removed as this is repetitive of the data collected as part of the primary outcome measure and its analysis. Additionally the outcome of "Pain scores following rotator cuff surgery" was further specified to Post-operative pain at rest and Post-operative pain with movement for clarification and analysis of each individually. This was also altered from a primary to secondary outcome to match the current IRB approved protocol for this study in which pain scores were a secondary outcome.
