Navigating Angiotensin II and Vasopressors in Critical Care

This chapter examines the role of angiotensin II as a vasopressor in critical care, particularly referencing the ATHOS-3 trial and the challenges in identifying responsive patients. The conversation highlights the potential for angiotensin II as a second-line option alongside vasopressin, and discusses vasodilator scavengers' role in managing vasoplegia. Additionally, the chapter addresses the benefits and considerations of using methylene blue and hydroxycobalamin, including their side effects and implications in critical care settings.
