Recognizing sepsis in children is one of those "don't miss" skills in paediatrics. It's all about spotting the subtle signs before things escalate. The NICE traffic light system is your best friend here for risk stratification.

Let's break down how to spot the red flags and what to do when you find them.

1. Recognition & The NICE Traffic Light System

NICE uses a "Traffic Light" system (Green, Amber, Red) to categorize the risk of serious illness in children under 5. For sepsis specifically, we look for clinical features that suggest organ dysfunction or poor perfusion.

• Red (High Risk): This is the "stop everything and treat" category.
  • Appearance: Pale/mottled/ashen/blue skin, lips, or tongue.
  • Responsiveness: Does not wake or stay awake; weak, high-pitched, or continuous cry.
  • Respiratory: Grunting, tachypnoea (RR >60), or chest indrawing.
  • Circulation: Reduced skin turgor or prolonged capillary refill time (CRT ≥3 seconds).
• Amber (Intermediate Risk): Requires close monitoring and likely investigation.
  • Appearance: Pallor reported by parent/carer.
  • Responsiveness: Not smiling; wakes only with prolonged stimulation; decreased activity.
  • Respiratory/Circulation: Nasal flaring, tachypnoea, or tachycardia.
• Green (Low Risk): Normal color, responsive, and hydrated.

2. Immediate Management: The Sepsis Six

If you suspect sepsis (especially if they hit any "Red" criteria), you need to initiate the Paediatric Sepsis Six within the first hour. It’s split into three things we give and three things we take/measure.

Give:

1. Oxygen: Aim for saturations >94% (or 88-92% if at risk of hypercapnic respiratory failure).
2. IV/IO Fluids: If shocked, give a 20 ml/kg bolus of isotonic crystalloid (e.g., 0.9% Sodium Chloride).
3. Antibiotics: Give the broadest spectrum possible according to local guidelines (usually a 3rd gen cephalosporin like Ceftriaxone).

Take/Measure: 4. Blood Cultures: Ideally before antibiotics, but don't let it delay treatment! 5. Lactate: A key marker of tissue perfusion. 6. Urine Output: Monitor closely (aim for >1 ml/kg/hr).

I'll pull up a table that summarizes these risk factors and the management steps clearly for your revision.
