Septic Shock: Initial Resuscitation and Management

Conclusión

Initial workup

• Activate sepsis screening, mark 'time zero,' and follow the Surviving Sepsis Campaign 3- and 6-hour bundles.
• Obtain blood cultures (and other site-specific cultures) before antibiotics when feasible, without delaying therapy.
• Measure an initial serum lactate and re-measure within 6 hours if elevated, to assess perfusion.
• Search for the source with a focused exam and imaging (e.g., CT abdomen/pelvis, chest X-ray) to guide source-control procedures.

Acute management

• Begin broad-spectrum IV antibiotics as early as possible, ideally within 1 hour of recognition — early administration is lifesaving.
• Initiate protocolized crystalloid resuscitation, titrated to physiologic targets such as a MAP ≥ 65 mmHg and adequate urine output.
• If hypotension persists after fluids, start norepinephrine as the first-line vasopressor; add vasopressin if additional pressor support is needed.
• Apply hemodynamic targets, consider transfusion where indicated, and reassess frequently within the first 6 hours.

Inpatient and longitudinal management

• Arrange definitive source control (drainage, debridement, device removal) as early as clinically feasible.
• Reassess daily for antibiotic de-escalation once culture data and the clinical response are available.
• Investigate and address organ dysfunction (renal replacement for severe AKI, ventilatory support for ARDS) per ICU protocols.
• Engage multidisciplinary care (pharmacy, infectious disease, nursing) to optimize bundle compliance and quality metrics.

Monitoring and disposition

• ICU-level care for all septic shock patients: continuous blood pressure, ECG, urine output, and serial lactates.
• Track adherence to SSC/SEP-1 time stamps (cultures, antibiotics, fluids, vasopressor start) for quality improvement.
• Step down from ICU when vasopressor-free for ≥ 24 hours, lactate has normalized, and there is no progressive organ failure.

Escalate care if

• MAP remains < 65 mmHg despite adequate fluids and norepinephrine ± vasopressin — consider escalation (e.g., epinephrine, corticosteroids) and advanced hemodynamic monitoring.
• Lactate fails to clear or rises — reassess volume status, cardiac function, and the infection source, and escalate ICU support.

Duration

Tailor the antibiotic course to the confirmed source (commonly 7–10 days) once hemodynamic stability is achieved.

Advertencias

• Modify aggressive fluid resuscitation in severe cardiogenic pulmonary edema or end-stage renal disease.
• Norepinephrine titration requires an arterial line and ICU monitoring.
