These complications, coupled with the ongoing opioid epidemic, have favored the rise of opioid-free-anesthesia (OFA). Herein, we perform the first pairwise meta-analysis of clinical outcomes for OFA vs opioid-based anesthesia (OBA) in patients undergoing cardiovascular and thoracic surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We comprehensively searched medical databases to identify studies comparing OFA and OBA in patients undergoing cardiovascular or thoracic surgery. Pairwise meta-analysis was performed using the Mantel\u2013Haenszel method. Outcomes were pooled as risk ratios (RR) or standard mean differences (SMD) and their 95% confidence intervals (95% CI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our pooled analysis included 919 patients (8 studies), of whom 488 underwent surgery with OBA and 431 with OFA. Among cardiovascular surgery patients, compared to OBA, OFA was associated with significantly reduced post-operative nausea and vomiting (RR, 0.57; P = .042), inotrope need (RR .84, P = .045), and non-invasive ventilation (RR, .54; P = .028). However, no differences were observed for 24hr pain score (SMD, \u2212.35; P = .510) or 48hr morphine equivalent consumption (SMD, \u22121.09; P = .139). Among thoracic surgery patients, there was no difference between OFA and OBA for any of the explored outcomes, including post-operative nausea and vomiting (RR, 0.41; P = .025).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Through the first pooled analysis of OBA vs OFA in a cardiothoracic-exclusive cohort, we found no significant difference in any of the pooled outcomes for thoracic surgery patients. Although limited to 2 cardiovascular surgery studies, OFA was associated with significantly reduced postoperative nausea and vomiting, inotrope need, and non-invasive ventilation in these patients. With growing use of OFA in invasive operations, further studies are needed to assess their efficacy and safety in cardiothoracic patients.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10892532231180227","type":"journal-article","created":{"date-parts":[[2023,6,10]],"date-time":"2023-06-10T09:50:25Z","timestamp":1686390625000},"page":"162-170","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":19,"title":["Opioid-free anesthesia versus opioid-based anesthesia in patients undergoing cardiovascular and thoracic surgery: a meta-analysis and systematic review"],"prefix":"10.1177","volume":"27","author":[{"given":"Dave M","family":"Mathew","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter J","family":"Fusco","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathryn S","family":"Varghese","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed K","family":"Awad","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Ain Shams University, Cairo, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eamon","family":"Vega","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serena M","family":"Mathew","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mia","family":"Polizzi","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jerrin","family":"George","sequence":"additional","affiliation":[{"name":"University of Toledo College of Medicine and Life Sciences, Toledo, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher S","family":"Mathew","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremiah J","family":"Thomas","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2020-5906","authenticated-orcid":false,"given":"Rose","family":"Calixte","sequence":"additional","affiliation":[{"name":"Epidemiology and Biostatistics, SUNY Downstate Health Sciences University, Brooklyn, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8998-8267","authenticated-orcid":false,"given":"Adham","family":"Ahmed","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine, New York, NY, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,6,10]]},"reference":[{"key":"bibr1-10892532231180227","doi-asserted-by":"publisher","DOI":"10.1037\/a0013628"},{"key":"bibr2-10892532231180227","doi-asserted-by":"publisher","DOI":"10.1016\/j.accpm.2018.05.002"},{"key":"bibr3-10892532231180227","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2018.05.053"},{"key":"bibr4-10892532231180227","unstructured":"Ferry N, Hancock LE, Dhanjal S.
