The incidence of tachyarrhythmias was similar between the non-DEX group and the DEX group (19% vs 15%, P = .34). When adjusted for baseline differences, the non-DEX group did not have an increased risk of postoperative tachyarrhythmias (odds ratio [OR]: 1.4, 95% confidence interval [CI]: 0.5-3.8). The non-DEX group had an increased need for treatment for arrhythmias (18% vs 8%, P = .012). The three lesions with baseline higher risk for arrhythmias (tetralogy of Fallot, transposition of the great arteries, and complete atrioventricular canal) had an increased incidence of tachyarrhythmias in the non-DEX group (34% vs 6%, P = .027). This risk was not significant in multivariate analysis (OR: 2.5, 95% CI: 0.4-15.5).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>High-risk infants had decreased incidence of tachyarrhythmias when receiving dexmedetomidine, though this was not significant after accounting for baseline differences between groups.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2150135119842873","type":"journal-article","created":{"date-parts":[[2019,7,16]],"date-time":"2019-07-16T00:37:16Z","timestamp":1563237436000},"page":"440-445","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Association Between Postoperative Dexmedetomidine Use and Arrhythmias in Infants After Cardiac Surgery"],"prefix":"10.1177","volume":"10","author":[{"given":"Laura A.","family":"Ortmann","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Division of Critical Care, Children\u2019s Hospital and Medical Center, Omaha, NE, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meera","family":"Keshary","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Division of Critical Care, Washington University School of Medicine, St Louis, MO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karl Stessy","family":"Bisselou","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, University of Nebraska Medical Center, Omaha, NE, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shelby","family":"Kutty","sequence":"additional","affiliation":[{"name":"Helen B.
