Question What is the effect on mortality at 90 days of reducing the exposure to vasopressors through permissive hypotension (mean arterial pressure target of 60-65 mm Hg) in intensive care unit (ICU) patients aged 65 years or older receiving vasopressors for vasodilatory hypotension? Findings In this randomized clinical trial that included 2600 patients aged 65 years or older with vasodilatory hypotension, treatment with permissive hypotension resulted in death at 90 days among 41.0% of patients compared with 43.8% of those receiving usual care, a difference that was not statistically significant.
