Management of Suspected Septic Shock

Initial Resuscitation and Assessment

The American College of Emergency Physicians and other societies recommend immediate aggressive resuscitation for presumed septic shock, including administering 30 mL/kg crystalloid fluid bolus within the first 3 hours, initiating broad-spectrum antibiotics within 1 hour, and starting norepinephrine as first-line vasopressor if hypotension persists after fluid resuscitation targeting mean arterial pressure ≥65 mmHg 1, 2
The Society of Critical Care Medicine suggests that the triad of fever, hypotension, and tachycardia strongly suggests septic shock—a life-threatening organ dysfunction caused by dysregulated host response to infection 1, 3
Critical vital sign thresholds indicating severe illness include tachycardia ≥110 beats/min 4, hypotension (systolic BP <90 mmHg or >20 mmHg below baseline) 3, and fever ≥38°C or hypothermia 3, 4

The Infectious Diseases Society of America recommends essential laboratory tests in patients with systemic toxicity, including blood cultures (before antibiotics) and drug susceptibility testing, complete blood count with differential, serum lactate level (>2 mmol/L indicates septic shock) 1, 3
Hospitalization is mandatory if hypotension is present, elevated creatinine, low serum bicarbonate, elevated creatine phosphokinase (2-3× upper limit of normal), marked left shift on differential, or C-reactive protein >13 mg/L 2, 3

The American College of Emergency Physicians recommends administering a minimum of 30 mL/kg crystalloid within the first 3 hours, which is the foundation of septic shock management and must precede or accompany vasopressor therapy 1, 2
The Society of Critical Care Medicine suggests initiating norepinephrine immediately if hypotension persists after adequate fluid resuscitation, targeting MAP ≥65 mmHg 2, 7
Alternative vasopressors, such as epinephrine, may be used if vasopressin is unavailable 2

The Infectious Diseases Society of America recommends administering broad-spectrum antibiotics within 1 hour of recognition, with the specific regimen depending on suspected source and local resistance patterns 1, 3
Urgent identification and control of the infection source are crucial, including imaging to locate infection, surgical consultation if indicated, and removal of potentially infected catheters 1, 2

The Society of Critical Care Medicine suggests assessing tissue perfusion using lactate clearance, urine output, mental status, and skin perfusion and capillary refill 2, 6
Common pitfalls to avoid include delaying antibiotics, using low-dose dopamine for renal protection, withholding vasopressors, targeting supranormal blood pressure, and attempting to pharmacologically lower compensatory tachycardia 1, 2, 5, 6
