Initial fluid resuscitation in septic shock should include isotonic crystalloid at 30 mL/kg within the first 3 hours, delivered as small boluses of about 500 mL.

Initial fluid resuscitation in septic shock should include isotonic crystalloid at 30 mL/kg within the first 3 hours, delivered as small boluses of about 500 mL.

• A. 5 mL/kg boluses
• B. 20 mL/kg over 60 minutes
• C. 30 mL/kg in the first 3 hours using small boluses of approximately 500 mL
• D. 100 mL/kg in 6 hours

Answer: (C)

Early aggressive volume resuscitation with isotonic crystalloids is the essential first step in septic shock to rapidly restore perfusion. The goal is about 30 mL/kg within the first 3 hours, given in small boluses (roughly 500 mL at a time) so you can repeatedly reassess the patient’s response after each aliquot. This approach pushes enough fluid to improve preload and tissue perfusion without flooding the circulation, which helps avoid fluid overload. After a few boluses, if the patient remains hypotensive or perfusion is not improving, vasopressors are started to maintain a mean arterial pressure of at least 65 mmHg. The other options fall short because they either provide too little fluid too slowly, or deliver a total volume that’s excessive (and risky) or not within the recommended early timeframe.
