Mean time on insulin infusion was shorter for those with euglycemic DKA: 13.5 vs 19.4 hours, <i>P</i> = 0.003. Mean times to first bicarbonate >18 mmol/L and first long-acting insulin were similar. Incidence of hypoglycemia (<70 mg/dL) while on insulin infusion was significantly higher for those with euglycemic DKA (18.2 vs 4.8%, <i>P</i> = 0.02); incidence of hypokalemia (<3.3 mmol/L) was 27.3 vs 19.1% (<i>P</i> = 0.23).</p><p><strong>Conclusion: </strong>Compared to hyperglycemic DKA patients managed in the same protocolized fashion, euglycemic DKA patients were on insulin infusions 5.9 hours less, yet experienced hypoglycemia over three times more frequently. Future work can investigate treatment strategies for euglycemic DKA to minimize adverse events, especially iatrogenic hypoglycemia.</p>","PeriodicalId":23682,"journal":{"name":"Western Journal of Emergency Medicine","volume":"24 6","pages":"1049-1055"},"PeriodicalIF":3.1,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10754195/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139075164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
