The study population was stratified by the development of limb necrosis following vasopressor use. Patients who experienced necrosis were compared with age- and sex-matched controls who did not experience necrosis. Demographic information, comorbidities, and medication details were recorded.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>The incidence of limb necrosis following vasopressor administration was 0.25%. Neither baseline demographics nor medical comorbidities differed significantly between groups. Necrosis was present in the same limb as the arterial catheter most often for femoral catheters. The vasopressor dose administered was significantly higher in the necrosis group than in the control group for ephedrine (P = .02) but not for the other agents. The duration of therapy was significantly longer in the necrosis group than in the control group for norepinephrine (P = .001), epinephrine (P = .04), and ephedrine (P = .01). The duration of vasopressin administration did not differ significantly between groups.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The findings of this study suggest that medication-specific factors, rather than patient and disease characteristics, should guide clinical management of necrosis in the setting of vasopressor administration.<\/jats:p>\n               <\/jats:sec>","DOI":"10.4037\/ajcc2024171","type":"journal-article","created":{"date-parts":[[2024,5,1]],"date-time":"2024-05-01T02:02:14Z","timestamp":1714528934000},"page":"226-233","source":"Crossref","is-referenced-by-count":7,"title":["Limb Necrosis in the Setting of Vasopressor Use"],"prefix":"10.4037","volume":"33","author":[{"given":"Kendall H.","family":"Derry","sequence":"first","affiliation":[{"name":"Kendall H.
