Guideline Recommendations on Beta‑Blocker Use in Septic Shock

Guideline Position

The Surviving Sepsis Campaign (2016‑2017) does not recommend beta‑blockers as a standard therapy for septic shock; the guidelines focus exclusively on norepinephrine as the first‑line vasopressor. [1][2]

Beta‑blockers should be avoided within the first 24 hours of septic shock onset because of the highest risk of hemodynamic decompensation. [1][2]
Beta‑blockers must not be used when initial fluid resuscitation is inadequate (i.e., less than 30 mL/kg of crystalloids has been administered). [1][2]
A mean arterial pressure (MAP) < 65 mmHg despite ongoing vasopressor therapy is an absolute contraindication to beta‑blocker administration. [1][2]
Presence of cardiac dysfunction or a low‑output state (requiring inotropic support) precludes beta‑blocker use. [1][2]

Fluid resuscitation: Deliver at least 30 mL/kg of crystalloid within the first 3 hours and continue as long as hemodynamic improvement is observed. [1][2]
Vasopressor optimization: Use norepinephrine as the first‑line agent, titrating to achieve a MAP ≥ 65 mmHg. [1][2]
Adjunct vasopressor: Add vasopressin at 0.03 units/min when additional vasopressor support is needed; this may reduce norepinephrine dose and associated tachycardia. [1][2]
Inotropic support: Consider dobutamine (2.5–20 µg/kg/min) for patients with persistent hypoperfusion despite adequate MAP, especially when myocardial dysfunction is evident. [1][2]
Reversible causes: Systematically treat pain, anxiety, fever, hypovolemia, anemia, and hypoxia as contributors to tachycardia. [1][2]

Do not substitute beta‑blockers for adequate fluid resuscitation or appropriate vasopressor therapy. [1][2]
Do not assume that tachycardia is harmful in septic shock; it may be a compensatory response to maintain cardiac output. [1][2]
Do not prioritize heart‑rate targets over perfusion endpoints such as lactate clearance, urine output, mental status, and capillary refill. [1][2]
Avoid dopamine for heart‑rate control, as it is linked to higher mortality and more arrhythmias compared with norepinephrine; reserve it only for selected patients with bradycardia. [1][2]
