    BackgroundAfter bariatric surgery, patients are at risk for narcotic-related side effects. Multimodal pain management strategies should be used when possible to reduce the consumption of narcotic medication. The purpose of this study was to investigate whether multimodal analgesia reduces narcotic consumption and may have an influence on opioid-related side effects in patients undergoing laparoscopic Roux-en-Y gastric bypass surgery (LRYGB).MethodsIn this retrospective data analysis, we examined the data of a total of 181 consecutive patients undergoing LRYGB. In January 2011, i.v. acetaminophen became clinically available. Hydromorphone patient controlled analgesia (PCA) was replaced by i.v. acetaminophen and i.v. ketorolac (TNT-Tylenol and Toradol). The first 89 patients received postoperative hydromorphone PCA (PCA group). The next 92 patients received i.v. acetaminophen and i.v. ketorolac every 6 hours for the first 24 hours (TNT group). In the TNT group, 8 patients were excluded in the analysis.ResultsThere were no differences in clinical characteristics between the groups except for smoking history. Patients treated with PCA required 4.2 mg hydromorphone in the postoperative period. Patients in the TNT group required 1.1 mg hydromorphone. This was a statistically significant reduction of opioids by 73.8%. After discharge from postanesthesia care unit, 34.8% of patients required antiemetic rescue medication (AERM) compared with 20.2% in the TNT group (P<.001). The relative risk (AERM/no AERM) in the postoperative period after postanesthesia care unit discharge is 1.75 (95% CI, 1.05-2.92).ConclusionThis study suggests that a multimodal analgesic regimen (TNT) can reduce postoperative narcotic consumption, which may lead to a reduction in the number of patients requiring AERM.Copyright © 2013 American Society for Bariatric Surgery.
