A 75-year-old woman with mild congestive heart failure is admitted to the intensive care unit with sepsis resulting from a urinary tract infection. She is hypotensive with a blood pressure of 80/44 mmHg, has an elevated heart rate (tachycardia), and decreased urine output (oliguria). In addition to institution of appropriate antibiotic therapy and IV fluids, the care team decides to start her on an IV infusion of a vasopressor to attempt to raise her blood pressure. Post your responses to the following questions in this forum: According to the sepsis treatment guidelines, what vasopressor should be used first line? What is the pharmacological action of this vasopressor? What microbe is most likely to cause this infection? What would be an appropriate IV antibiotic to start this patient on? If this patient were in an outpatient setting and you were treating a UTI, what would be an appropriate antibiotic in this case?
