What is the approach to suspected septic shock in a dog, including early resuscitation targets?

• A. Recognize tachycardia, tachypnea, hypotension; obtain cultures; start broad-spectrum antibiotics promptly; aggressive IV fluids (balanced crystalloids) and vasopressors if hypotension persists; monitor lactate and urine output.
• B. Start antibiotics after 48 hours; avoid fluids.
• C. Only fluids; no antibiotics.
• D. Withhold cultures; use steroids.

Answer: (C)

Suspected septic shock requires rapid stabilization aimed at restoring perfusion while addressing the underlying infection. Begin broad-spectrum antibiotics promptly and obtain cultures (including blood cultures) as part of the initial workup, but do not delay antibiotic therapy while waiting for culture results. Start aggressive fluid resuscitation with balanced crystalloids to improve circulating volume and tissue perfusion, and reassess response using lactate levels and urine output. If hypotension persists after fluids, add vasopressor support to maintain an adequate mean arterial pressure. Monitor perfusion indicators, lactate clearance, and urine output to guide ongoing resuscitation, aiming for a downward lactate trend and sufficient urine production. Prefer balanced crystalloids to minimize electrolyte and acid-base disturbances. Steroids are not routinely indicated, and delaying antibiotics or withholding cultures would miss essential elements of sepsis management.
