Early vasopressin start was independently associated with decreased hospital mortality (aOR = 0.69, 95% CI = 0.57-0.83). Vasopressin infusion start was also associated with an immediate decrease in the noradrenaline-equivalent dose regardless of timing. There was a statistically significant favourable breakpoint at vasopressin start for the course of arterial pH, lactate, heart rate and crystalloid infusion rate (p<0.001).</p><p><strong>Conclusions: </strong>In patients with septic shock, early adjunctive vasopressin initiation was independently associated with lower hospital mortality. Vasopressin starting at any time was also associated with reduced tachycardia, acidosis, and hyperlactatemia.</p>","PeriodicalId":49215,"journal":{"name":"Critical Care and Resuscitation","volume":"26 4","pages":"295-302"},"PeriodicalIF":1.4,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11704155/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142957562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
