Background: The opioid epidemic demands changes in perioperative pain management. Of the 33,000 deaths attributable to opioid overdose in 2015, half received prescription opioids. Multimodal analgesia is a practice-altering evolution that reduces reliance on opioid medications. Ambulatory breast surgery is an ideal opportunity to implement these strategies.
Methods: A retrospective review of 560 patients undergoing outpatient breast procedures was conducted. Patients received (1) no preoperative analgesia (n = 333); (2) intraoperative intravenous acetaminophen (n = 78); (3) preoperative oral acetaminophen and gabapentin (n = 95); or (4) preoperative oral acetaminophen, gabapentin and celecoxib (n = 54). Outcomes included postanesthesia care unit narcotic use, pain scores, postanesthesia care unit length of stay, rescue antiemetic use, and 30-day complications. Results: Both oral multimodal analgesia regimens significantly reduced postanesthesia care unit narcotic use (oral acetaminophen and gabapentin, 14.3 ± 1.7; oral gabapentin, acetaminophen, and celecoxib, 11.9 ± 2.2; versus no drug, 19.2 ± 1.1 mg oral morphine equivalents; p = 0.0006), initial pain scores (oral acetaminophen and gabapentin, 3.9 ± 0.4; oral gabapentin, acetaminophen, and celecoxib, 3.4 ± 0.7; versus no drug, 5.3 ± 0.3 on a 1 to 10 scale, p = 0.0002) and maximum pain scores (oral acetaminophen and gabapentin, 4.3 ± 0.4; oral gabapentin, acetaminophen, and celecoxib, 3.6 ± 0.7; versus no drug, 5.9 ± 0.3 on a 1 to 10 scale; p < 0.0001). Both oral regimens were better than no medications or intravenous acetaminophen alone in multivariate models after controlling for age, body mass index, American Society of Anesthesiologists class, length of surgery, prior narcotic prescription availability, and intraoperative local anesthetic. Postanesthesia care unit length of stay, antiemetic use, and 30-day complications were not different.
Conclusions: Preoperative oral multimodal analgesia reduces narcotic use and pain scores in outpatient breast plastic surgery. These regimens are inexpensive, improve pain control, and contribute to narcotic-sparing clinical practice in the setting of a national opioid epidemic.
