Surviving Sepsis Campaign international guidelines children sepsis septic shock 2026 recommendations
These results (all drawn 11 Feb 2025, 18:53 to 21:04, in a 12-year-old boy) show severe metabolic derangement with several organs affected at once. The pattern fits severe sepsis or septic shock with multi-organ dysfunction until proven otherwise. I can't say what the cause is from labs alone. If this child is still unwell, he needs urgent in-person critical care assessment.
Results by system
| System | Findings | Meaning |
|---|---|---|
| Blood gas (likely venous) | pH 7.142, HCO3 14.2, BE -14.3, lactate 10.36 (normal 1 to 1.8), pCO2 42.5, pO2 27.9, SO2 40% | Severe lactic acidosis. The low pO2 and SO2 mean this is a venous sample, so they are not true oxygenation values. |
| Anion gap | 135.9 - (97 + 14.2) = about 24.7 | High anion gap acidosis. The rise in gap roughly matches the fall in bicarbonate, so this is a pure lactic acidosis. Albumin wasn't measured. |
| Respiratory compensation | Expected pCO2 is about 29 (Winter's formula). Measured is 42.5. | A venous pCO2 runs about 4 to 6 mmHg above arterial, so arterial pCO2 is probably 37 to 38. That is still higher than expected, so he may not be compensating well (tiring, or a ventilation problem). |
| Kidney | Creatinine 254 µmol/L (about 2.9 mg/dL, reference 0 to 70), urea 15.55 | Acute kidney injury, probably severe. A baseline creatinine would confirm. |
| Liver | ALT 84.7, AST 102.2, total bilirubin 39.5, direct 15.7. GGT and ALP are normal. | Hepatocellular injury with mixed hyperbilirubinemia. Normal GGT and ALP argue against bile duct obstruction. Sepsis-related liver dysfunction or poor perfusion fits. |
| Coagulation | PT 23 s, INR 2.09, PI 36%, aPTT 48.1 (borderline high), fibrinogen 4.13 (high-normal), TT normal | Prolonged PT/INR. Impaired liver synthesis, vitamin K deficiency or early consumption could all contribute. A high-normal fibrinogen and near-normal platelets make overt DIC less likely right now, but this can change quickly. |
| CBC | WBC 1.12, neutrophils 0.58, lymphocytes 0.44, monocytes 0.05, platelets 153 (low-normal), Hb 152 | Marked leukopenia with moderate neutropenia and lymphopenia. In sepsis this can mean overwhelming infection. Marrow suppression or a viral cause are also possible. |
| Hemoconcentration | Gas tHb 16.1, Hct 47, RBC 5.41 (slightly high) | Suggests volume depletion. |
| Inflammation | CRP 279 mg/L, ESR 9 | A very high CRP points to a severe systemic inflammatory response, probably bacterial. ESR lags behind in the first hours, so a normal value is not reassuring. |
| Electrolytes | K 3.48 (low), ionized Ca 1.03 (low), Na 135.9, glucose 93 | Mildly low potassium and calcium. Both need monitoring and correction, particularly as the acidosis is treated. |
What the whole picture suggests
-
Shock with hypoperfusion: lactate above 10 plus AKI, liver injury and abnormal clotting show several organs failing together. The Tintinalli textbook describes septic shock as sepsis needing vasopressors after adequate resuscitation with an elevated lactate. Pediatric sepsis chapters in Rosen's Emergency Medicine describe the same picture.
-
Leukopenia with severe inflammation carries a worse outlook than a high WBC in sepsis, and it widens the differential. The causes to consider include:
- overwhelming bacterial sepsis, such as meningococcal or toxic shock;
- a severe viral or hemorrhagic illness (Crimean-Congo hemorrhagic fever occurs in Georgia, though the near-normal platelets and high fibrinogen fit it less well);
- hemophagocytic syndrome;
- an underlying hematologic cause.
Clinical history and exam decide this, not these labs. -
Alternatives to exclude: severe dehydration or gastrointestinal loss, toxin or drug ingestion, and an acute abdominal catastrophe.
What current guidance emphasizes
The 2026 Surviving Sepsis Campaign pediatric guidelines recommend:
- measuring lactate early;
- taking blood cultures before antibiotics, as long as that doesn't delay them;
- guiding resuscitation by ongoing clinical reassessment.
A SCCM session on the update also describes a more conservative oxygen target of 88 to 92% SpO2 as a conditional suggestion for children with septic shock. These came from my search results and I haven't read the full guideline text.
Missing information that changes the interpretation
- Vital signs: blood pressure, heart rate, capillary refill, temperature, respiratory rate, mental state, urine output.
- Blood cultures, procalcitonin, and a peripheral smear.
- Albumin and a repeat lactate to show the trend.
- Whether the gas was arterial or venous, and the child's baseline creatinine.
- Symptoms: fever, vomiting or diarrhea, rash, tick exposure, abdominal pain, medications or ingestions.
I don't know the child's clinical course or outcome. I haven't verified anything in the documents beyond the printed values.
If you tell me whether you're a clinician or a family member, and what you want to know (for example a specific value, next steps, or a differential), I can focus on that. I can also set out a differential for neutropenia with coagulopathy and hepatitis.
Recent literature check
The recent reviews I found are the 2026 pediatric SSC guideline (PMID 41870559) and a 2025 meta-analysis on corticosteroids in pediatric septic shock (PMID 39348497). Nothing I saw contradicts the interpretation above.
