Neonatal Sepsis Diagnosis and Management Guidelines
Diagnostic Clinical Signs (0‑7 days)
- Feeding difficulty is recognized as a key clinical manifestation for diagnosing neonatal sepsis in newborns (0‑7 days) 1.
Systematic Screening of Febrile Infants (8‑60 days)
- All infants aged 8‑60 days with fever should undergo systematic screening to enable early detection of septic shock and associated organ dysfunction 2.
- Blood cultures must be obtained before the first dose of antibiotics unless obtaining the culture would cause a clinically significant delay in therapy 2.
Age‑Specific Evaluation Criteria
- 8‑21 days: Complete evaluation—including blood, urine, and cerebrospinal fluid cultures—must be performed before initiating antibiotics [3][1].
- 22‑28 days: Similar evaluation is recommended, with the option to observe without immediate therapy after a risk‑benefit discussion [3][1].
- 29‑60 days: Evaluation is tailored to the infant’s clinical presentation and urinalysis results 1.
Timing of Empiric Antibiotic Initiation
- For infants with septic shock, empiric antibiotics should be started within 1 hour of identification (strong recommendation) 3.
- For infants with organ dysfunction but no shock, empiric antibiotics should be started within 3 hours of identification (weak recommendation) 1.
Empiric Antibiotic Regimens by Age and Clinical Focus
| Age / Clinical Situation | Recommended Empiric Regimen |
|---|---|
| 8‑21 days (no specific focus) | Ampicillin + Ceftazidime or Ampicillin + Gentamicin [3] |
| 22‑60 days (no identified focus) | Ceftriaxone [3] |
| Suspected bacterial meningitis (any age) | High‑dose Ampicillin (300 mg/kg/day divided q6 h) plus Ceftazidime or Ceftriaxone [3] |
Discontinuation of Antibiotic Therapy
- Antibiotics may be stopped after 24‑36 hours when all of the following are met: negative cultures, clinical improvement, no ongoing need for hospitalization, and absence of another infection requiring therapy 1.
Laboratory Risk Stratification
- Blood lactate measurement should not be used for risk stratification in children with suspected sepsis; no recommendation supporting its use is provided 2.
