Subpectoral Bupivacaine for Pain Management in Adolescent Reduction Mammaplasty
Study Details
Study Description
Brief Summary
The goal of this randomized control trial is to in [describe participant population/health conditions]. The main question it aims to answer is:
• Is the use of intraoperative subpectoral bupivacaine associated with decreased post-operative pain in adolescent patients who undergo bilateral reduction mammaplasty
Participants will be randomized into the study group that intraoperatively receives 20cc of subpectoral bupivacaine injections or into the control group that intraoperatively receives 20cc of injectable saline subpectorally. All participants will keep a pain log and pain medication log at home for the first week following surgery.
Researchers will compare to see if patients who receive subpectoral bupivacaine have lower pain scores in the PACU, and lower use of narcotics post-operatively when compared to the control group who receive injectable saline.

Detailed Description
-
All team members will be extensively trained on the proceedings of this trial
-
Patients will be recruited at their initial consultation, or subsequent pre-operative visit.
-
All patients that are approached will be recorded into an excel sheet. If they decline the study- this will be listed along with any provided reasoning for declining.
-
Once consent is obtained, the patient will be randomized into either the study group (receiving intraoperative subpectoral bupivacaine) or the control group (will not receive subpectoral bupivacaine.) Block randomization will be performed using randomizer.org. For every forty patients, twenty will be randomized into the control group, and twenty into the bupivacaine group. Patients will be blinded to the which group they are placed in. The PI and study staff are not blinded.
-
Per standard protocol, patients will undergo urine pregnancy testing in the pre-operative area. If results are positive, patients will be informed of the results in a private area. Surgery will be postponed and patients will be then excluded from the study.
-
Patients will undergo their procedure with their assigned intervention. Intra-operative anesthetic and pain control regimens will otherwise be standardized with the anesthesia team to remove other confounding factors/variables.
-
Administration of the saline/bupivacaine will be just below the fascia of the pectroalis major. This will occur following resection of the specimen and achievement of hemostasis, prior to closure of the wounds. Injections will be in a fan-like pattern, beginning at the inferolateral border of the pectoral is muscle, extending superomedially with injection, spanning the anterior surface of the pectroalis major. This will be performed under direct visualization; no imaging assistance is necessary. Each patient will receive 5 injections, 3mL per injection bilaterally. A total of 30mL of saline or bupivacaine will be injected.
-
PACU nurses will record pain scores upon arrival into the PACU, as well as upon discharge home from the hospital. All patients will receive the same amount of prescribed narcotic. They will be sent home with a log. Patients will record a daily pain score, and the number of doses of ibuprofen, acetaminophen and oxycodone.
-
As an internal quality control measure, research staff will call patients within 72 hours from surgery to ensure they are completing the pain score and medication log daily.
-
The clinician (MD, PA, or nurse) will go through the survey questions with patients at their 1 and 4 week post-operative visits. These questions are typical questions asked at follow-up and will not add significant time to the clinic visit. All clinical staff asking these surveys is familiar with the information. (see appendices)
-
Data will be collected at the 1 and 4 week post-operative visit in the plastic surgery clinic Further data (PACU length of stay, PACU pain scores) will be determined by performing chart review.
-
To minimize error and maximize quality, only a few clinicians (3-4 max) will be those obtaining the survey results in clinic. All questions will be asked by reading verbatim from the survey to avoid bias when questioning. Scores will be entered into an excel file each day at the end of clinic.
-
The spreadsheet will be password protected to ensure patient privacy. Only the surgeon, PA and RN will have access to this.
-
Interim analyses will be performed after 60 patients have undergone treatment in order to assess if the study is meeting the intended objectives.

Outcome Measures
Primary Outcome Measures
- Post-operative pain score [Measured on day of surgery]
Post-operative pain score will be patient reported on a rating scale of 1-10. This will be recorded by the PACU nurse upon admission and upon discharge from the PACU. Patients will subsequently record a daily pain score in a home log daily until their 1 week follow-up visit. Scores will be recorded using the home log provided by the patient. We will also utilize chart review to record PACU pain score from the immediate post-operative time period.
Secondary Outcome Measures
- Narcotic use [Measured up until 4 weeks post-op]
Narcotic use will be determined by chart review of the PACU record. The amount of narcotic pain medication will be recorded for each patient. Prescription narcotic use upon discharge will be patient-reported in their patient log.
- Length of stay in post-anesthesia care unit [Measured on day of surgery]
Length of stay in post-anesthesia care unit will be determined by chart review from time entering the PACU to time of discharge from the hospital.
- Return to full activity [Measured for 4 weeks post-op]
Return to full activity- will be categorized as returning to school, returning to light activity, or returning to full activity/heavy exercise.
- Demographics [Recorded when patient is enrolled]
Demographics including age, race, ethnicity will be collected and recorded for all patients approached to enter the study.
