Management of Septic Shock – Evidence‑Based Recommendations

Immediate Recognition and Initial Resuscitation

Initiate treatment the moment septic shock is recognized; it is a time‑critical emergency. Strong recommendation. 1
Give at least 30 mL kg⁻¹ of intravenous crystalloid within the first 3 hours of sepsis‑induced hypoperfusion. Strong recommendation. 1
Employ a dynamic fluid‑challenge: continue fluids only while cardiac output, pulse‑pressure variation, stroke‑volume variation, arterial pressure, or heart‑rate improve, and stop when the response plateaus to avoid volume overload. Strong recommendation. 2
In patients who require vasopressors, target an initial mean arterial pressure (MAP) of ≥ 65 mm Hg. Strong recommendation. 1
Use lactate normalization as a surrogate marker of adequate tissue perfusion during resuscitation. Strong recommendation. 1

Crystalloids are the first‑line fluid for both initial resuscitation and ongoing volume replacement. Strong recommendation. 2
Balanced crystalloids (e.g., lactated Ringer’s, Plasma‑Lyte) are preferred over normal saline because they are associated with a lower risk of renal dysfunction, although either may be used. Strong recommendation. 1
Albumin should be added to crystalloids only when large volumes of crystalloid are required; this is a weak recommendation based on low‑quality evidence and should not be routine. 2
Hydroxyethyl starches must never be used for volume replacement in septic shock; strong evidence links them to an increased need for renal replacement therapy. Strong recommendation. 2
Gelatin solutions should be avoided; crystalloids remain the preferred choice. Strong recommendation. 2

Norepinephrine is the first‑choice vasopressor and should be started early when fluid resuscitation alone does not achieve MAP goals. Strong recommendation. 2
Vasopressin (up to 0.03 U min⁻¹) or epinephrine may be added to norepinephrine when additional support is needed to reach MAP target or to reduce norepinephrine dose. Strong recommendation. 2
Dopamine is reserved for highly selected patients with low risk of tachyarrhythmias and absolute or relative bradycardia; it is not a first‑line agent. Strong recommendation. 2
Low‑dose vasopressin should not be used as the sole initial vasopressor; higher doses (> 0.03–0.04 U min⁻¹) are reserved for salvage therapy when other agents fail. Strong recommendation. 2

Obtain appropriate microbiologic cultures (including at least two sets of blood cultures) before starting antimicrobials, but do not delay antibiotic administration if this would cause a substantial postponement. Strong recommendation. 1
Deliver broad‑spectrum intravenous antimicrobials within 1 hour of recognizing sepsis or septic shock, covering likely bacterial, fungal, and viral pathogens. Strong recommendation. 1
De‑escalate to narrower‑spectrum therapy once the pathogen and its susceptibilities are identified or when clear clinical improvement is evident. Strong recommendation. 1
Optimize dosing using pharmacokinetic/pharmacodynamic principles and drug‑specific characteristics. Strong recommendation. 1

Promptly remove any intravascular access devices that could be the source of infection after alternative vascular access has been secured. Strong recommendation. 2

Frequently reassess hemodynamic status after the initial fluid bolus to guide further fluid administration. Strong recommendation. 1
Perform additional hemodynamic evaluation (e.g., cardiac function assessment) when the clinical exam does not clarify the type of shock. Strong recommendation. 1
Prefer dynamic variables (pulse‑pressure variation, stroke‑volume variation) over static measures to predict fluid responsiveness whenever available. Strong recommendation. 1
