Management of Septic Shock with Hypotension and Lactic Acidosis

Immediate Priorities (First Hour)

The American College of Critical Care Medicine recommends administering crystalloid fluid boluses of 500-1000 mL over 30 minutes immediately to restore adequate cardiac filling pressures and maintain mean arterial pressure ≥65 mmHg 1, 2
Target central venous pressure 8-12 mmHg, urinary output ≥0.5 mL/kg/h, and central venous oxygen saturation ≥70% 2
The Society of Critical Care Medicine suggests starting broad-spectrum antibiotics within the first hour of documented hypotension—each hour of delay decreases survival by 7.6% 2
Initial empiric regimen should include meropenem, imipenem/cilastatin, or piperacillin/tazobactam as monotherapy, as recommended by the Infectious Diseases Society of America 2

The European Society of Intensive Care Medicine recommends initiating norepinephrine at 0.1-1.3 μg/kg/min if mean arterial pressure remains <65 mmHg despite adequate fluid resuscitation 1, 2
Norepinephrine is superior to dopamine and causes less tachycardia and arrhythmias, according to the American Heart Association 1, 5

The American College of Critical Care Medicine recommends targeting mean arterial pressure ≥65 mmHg 1, 2
Target urine output ≥0.5 mL/kg/h, as suggested by the National Institute of General Medical Sciences 2, 6
Monitor lactate clearance to assess tissue perfusion and resuscitation response, as recommended by the Society of Critical Care Medicine 4, 5

The American College of Emergency Physicians advises against continuing aggressive fluid boluses if signs of volume overload appear—this can precipitate pulmonary edema and respiratory failure 2, 3
Avoid delaying vasopressor initiation in patients who remain hypotensive after 2-3 liters of crystalloid, as recommended by the European Society of Intensive Care Medicine 5
The Infectious Diseases Society of America recommends against using albumin for resuscitation—meta-analyses show no benefit and possible harm 2
