Pain Management Study

The majority of patients who undergo surgery will require treatment for the management of acute post-surgical pain. The use of narcotics after elective surgical procedures has contributed to the current opioid epidemic. Striking the right balance of treatment and use of narcotics vs. non-narcotic medications is at a crucial juncture in surgery. Post-surgical pain influences a patient's perception of quality of care, physical recovery, and length of stay. The threat of poor postoperative pain control is a fear of many patients who will have a surgical procedure. The post- operative pain regimen is traditionally chosen by the operating surgeon rather than in a shared decision-making model where patients are educated about choice and participate in management. This is one of many factors influencing use of medications for post-operative pain. If a patient develops longer term, chronic postsurgical pain it may lead to disability and diminish quality of life, increase healthcare utilization, increase healthcare costs, and result in loss of productivity. Morbid obesity is a global epidemic that increases the risk of developing related complications such as cardiac failure, type 2 diabetes, hypertension, hyperlipidemia, degenerative joint disease with the development of chronic pain and decreased mobility, and sleep apnea. In 2013 and 2014, 50% of the population had or had been affected by obesity, defined as a BMI ≥30mg/kg2. An established and effective treatment for weight loss is elective bariatric surgery. Laparoscopic bariatric surgery (\>90% of cases) is associated with less postoperative pain than open surgery, however, opioids are still used frequently for analgesia. Opioid analgesia comes with many side effects including nausea, constipation, risk of postoperative ileus, hypopnea, hypoxemia, delayed ambulation and mortality. This patient population is at increased risk for hypoventilation and narcotic related post-operative complications. In the BUMCP department of bariatric surgery, we began employing a post-operative multimodal pain control protocol in November of 2017 and noticed improvement in pain control, declining levels of nausea and a decrease in the length of stay with our patient population. All medications and surgical interventions are considered approved standard of care in surgery. Previous studies have shown that employing a multimodal pain control protocol, even intraoperatively, influences postoperative pain control, nausea, emesis as well as chronic postoperative pain. In mid-2018 we began offering patients tap blocks which we believe have offered patients more consistent post- operative pain control. Postsurgical pain control is imperative as it influences a patient's quality of care and life, recovery, and length of stay. Poor pain control can not only lead to increased healthcare utilization/costs, whereas use of opioid analgesia comes with side effects including nausea, constipation, risk of postoperative ileus, hypopnea, hypoxemia, delayed ambulation, mortality, and the increased possibility of long-term narcotic addiction. In the population that suffers from obesity it is desirable to reduce the narcotics being used as they are at increased risk for hypoventilation and post-operative complications. The BUMCP bariatric surgery department began employing a post-operative multimodal pain control protocol and noticed improvement in pain control, a decrease in perioperative morbidity from narcotic use and a decreased length of stay in the elective patient population undergoing primary bariatric surgery. This study will contribute to our knowledge of whether a non-narcotic, multi-modal post-operative pain management protocol is equivalent, if not superior in multiple facets compared to narcotic use. Objectives Study Hypothesis: The use of a multi-modal, non-narcotic pain management regimen in postoperative bariatric patients will have equivalent, if not superior, postoperative outcomes compared with patient receiving narcotic pain management regimen. Those patients receiving a TAP block will have better pain control in the first 24 hours post-op. Primary outcome measure: Patient reported postoperative pain using the Wong Baker Faces pain scale (mean of all reported scores till the earlier of discharge and 24 hours postoperative). Secondary outcomes measures: * Postoperative nausea numerical rating scale (0-5) * Length of time before subject can complete 200 feet of ambulation post-op * Hospital length of stay * Readmissions for pain control up to 30-day postoperatively (as binary Yes/No and also as a count variable)
