Use of High-Dose Hydroxocobalamin for Septic Shock: A Case Report.

In this case report, we describe 2 patients with septic shock requiring high-dose vasopressors for hemodynamic support despite aggressive fluid resuscitation. After the administration of high-dose hydroxocobalamin for presumed septic vasoplegic syndrome, both patients had an immediate response to hydroxocobalamin with a rapid and lasting improvement of blood pressure that significantly reduced the need for vasopressor support.
