[ Frequently Asked Questions ](#blog-faqs) 11. [ References ](#references-heading) A child with septic shock can receive perfect fluids, antibiotics, and vasoactives—and still die if the infected collection remains untouched. Source control is not an “after the PICU transfer” task. Treat it like an airway problem: identify it early, call for help early, and do not let imaging become the reason definitive care is delayed. The Mental Model: Antibiotics Buy Time, Source Control Wins Time ---------------------------------------------------------------- In pediatric septic shock, antibiotics reduce microbial burden, but abscesses, necrotic tissue, obstructed systems, and infected foreign bodies often need a procedure. The 2026 Surviving Sepsis Campaign pediatric guidelines state that emergent source control should occur as soon as possible once an infection amenable to a procedure is diagnosed, with diagnostic testing and specialist input used to prioritize interventions. [\[1\]](#cite-1 "Reference [1]") Think in four buckets: - **Drain** pus: abscess, empyema, septic joint, complicated appendicitis. - **Debride** dead tissue: necrotizing fasciitis, clostridial myonecrosis, infected burns. - **Relieve obstruction**: obstructed pyelonephritis, cholangitis, infected hydronephrosis. - **Remove infected hardware**: central line, VP shunt, prosthetic material when confirmed or strongly implicated. For boards, the trap is escalating pressors while ignoring the source. Persistent shock after appropriate antibiotics should make you ask, “What needs to come out?” When to Call Surgery, IR, or Another Procedural Team ---------------------------------------------------- Do not wait for the lactate to normalize before consulting. Shock physiology is often the reason to accelerate source control, not postpone it. Involve pediatric surgery, interventional radiology, orthopedics, neurosurgery, urology, ENT, or infectious diseases based on the suspected focus. ### Consultation triggers you should not miss Call early when you see: - Peritonitis, free air, toxic megacolon, necrotizing enterocolitis, or perforated appendicitis. - Rapidly progressive soft tissue infection, pain out of proportion, bullae, crepitus, skin anesthesia, or shock with cellulitis. - Septic arthritis, especially hip or shoulder involvement. - Pleural empyema with respiratory compromise or persistent sepsis. - Obstructed urinary tract infection or infected stone. - Persistent bacteremia or candidemia with a central venous catheter. - VP shunt infection, CNS abscess, or hardware-associated infection. > **Clinical Pearl:** In a child with septic shock and a focal exam, “too unstable for surgery” is rarely the final answer. The better question is, “What resuscitation, airway plan, blood product, or vasoactive strategy gets this child safely to source control?” Imaging Strategy: Find the Source Without Losing the Patient ------------------------------------------------------------ Imaging should answer a management question: Is there something to drain, debride, remove, or decompress? Do not order a CT abdomen because “sepsis needs a source” if the child is on escalating vasoactives and unsafe for transport. Use a staged approach: 1. **Bedside first:** exam, POCUS when expertise exists, chest radiograph, line assessment, skin and joint exam. 2. **Ultrasound when useful:** abdomen, pelvis, urinary tract, pleural space, soft tissue, hip effusion. 3. **CT or MRI after stabilization:** deep neck infection, intra-abdominal abscess, CNS infection, osteomyelitis complications. 4. **Procedure-linked imaging:** coordinate imaging with IR or surgery so a drainable collection becomes a drained collection. Board exams love the unstable meningitis scenario. If bacterial meningitis is suspected and the child is in shock, obtain blood cultures if feasible, give antibiotics immediately, and defer lumbar puncture until safe. Cultures: Be Fast, Targeted, and Honest About Delays ---------------------------------------------------- The 2026 pediatric SSC guidance supports obtaining blood cultures before antimicrobials when doing so does not substantially delay treatment; for suspected septic shock, antimicrobials should begin as soon as possible, ideally within 1 hour of recognition. [\[1\]](#cite-1 "Reference [1]") Practical culture strategy: - Draw blood cultures promptly; prioritize adequate blood volume over ritualistic low-volume sets. - If a central line is present, obtain cultures from the line and a peripheral site when possible. - Culture the suspected focus: urine, CSF when safe, tracheal aspirate, wound, joint fluid, abscess fluid, or operative specimen. - Do not delay antibiotics for LP, CT, urine bag collection, or a difficult peripheral stick. - Re-culture persistent bacteremia, candidemia, or clinical deterioration despite therapy. A common exam pitfall is treating cultures as source control. Cultures identify the enemy; they do not evacuate pus. Adjunctive Therapy: Steroids Are Not a Substitute for Source Control -------------------------------------------------------------------- Adjunctive therapy should be disciplined. Current pediatric guidance suggests against IV hydrocortisone when hemodynamic stability is restored with fluids and vasoactive therapy, and finds insufficient evidence to recommend for or against hydrocortisone when shock remains unstable despite both. Stress-dose corticosteroids are appropriate for suspected or documented adrenal insufficiency. [\[1\]](#cite-1 "Reference [1]") ### Catecholamine-resistant shock: the useful concept Catecholamine-resistant shock means ongoing hypoperfusion or hypotension despite adequate intravascular resuscitation and escalating vasoactive support. In that scenario, hydrocortisone is not “routine sepsis treatment”; it is a targeted rescue consideration, especially if adrenal insufficiency is plausible. Consider adrenal risk when there is: - Chronic systemic steroid exposure. - Known adrenal or pituitary disease. - Congenital adrenal hyperplasia. - Purpura fulminans or meningococcemia with refractory shock. - Recent etomidate exposure, noting pediatric sepsis guidelines suggest avoiding etomidate for intubation. [\[1\]](#cite-1 "Reference [1]") Also avoid the “kitchen sink” reflex. The 2026 guidance suggests against routine vitamin C, thiamine, vitamin D repletion without deficiency, and routine IVIG for pediatric sepsis or septic shock. [\[1\]](#cite-1 "Reference [1]") Key Takeaways ------------- - Source control is a resuscitation priority, not a cleanup step. - Call procedural teams early for drainable pus, necrotic tissue, obstruction, or infected hardware. - Image only when it changes management and can be done safely. - Obtain cultures before antibiotics only if this does not delay therapy. - In suspected septic shock, antibiotics should start ideally within 1 hour of recognition. - Hydrocortisone is not routine; reserve it for refractory shock considerations or adrenal insufficiency. Conclusion ---------- Advanced pediatric septic shock care is won by pairing physiology with logistics. Keep the child perfused, give antimicrobials fast, but relentlessly ask what source needs a procedure. On rounds, in the ED, and on boards, the safest clinician is the one who recognizes that pressors cannot drain an abscess. Frequently Asked Questions ---------------------------- ### Should blood cultures delay antibiotics in pediatric septic shock? No. Obtain blood cultures first only if they do not substantially delay antimicrobials. In suspected septic shock, antibiotics should begin as soon as possible, ideally within 1 hour. ### When should surgical consultation happen in pediatric septic shock? Consult early for suspected abscess, perforation, necrotizing infection, obstructed infection, septic joint, infected hardware, or persistent shock without clear source control. ### Is CT required before source control? No. CT is helpful when it changes management and the child is safe for transport. Use bedside exam, ultrasound, POCUS, and procedure-directed imaging when unstable. ### When are steroids appropriate in pediatric septic shock? Do not use hydrocortisone routinely if fluids and vasoactives restore stability. Consider stress-dose steroids for suspected adrenal insufficiency or refractory catecholamine-resistant shock after expert consultation. References (2) ------------------ 1. 1.
