Care priority and warning signs

Care priority

Immediate Treatment (Plan C) / Refer URGENTLY

Red flags

  • Lethargy / Unconsciousness / No movement
  • Skin pinch > 2 seconds
  • Signs of shock (cold periphery, poor capillary refill, weak pulse)
  • Inability to feed/take fluids
  • Associated signs of PSBI/Very Severe Disease

Assessment

  • Ask: Does the young infant have diarrhoea? (Note: Stools are normally frequent/semisolid in breastfed babies. Diarrhoea is a change to many watery stools).
  • Look/Feel: Look at the infant's general condition/movements. Is the infant lethargic or unconscious? Moves only when stimulated or no movement at all?
  • Look/Feel: Look for sunken eyes.
  • Look/Feel: Pinch the skin of the abdomen. Does it go back Very slowly (longer than 2 seconds)?

Classification

  • Two or more of the following signs: (Movement only when stimulated or no movement at all / Lethargic or unconscious) OR (Sunken eyes) OR (Skin pinch goes back very slowly) -> SEVERE DEHYDRATION

Key features

  • Requires TWO or more of the following signs: Lethargic/unconscious OR Movement only when stimulated/no movement OR Sunken eyes OR Skin pinch goes back very slowly (>2 seconds).
  • Indicates severe fluid and electrolyte loss, which is particularly dangerous in young infants.
  • Requires immediate fluid resuscitation, preferably IV or NG if trained (Plan C), and urgent referral.

Management

Non-pharmacological management

  • If providing Plan C in clinic: Ensure immediate access to IV/NG equipment and ORS. Monitor closely.
  • If referring: Keep infant warm. Continue ORS sips frequently if possible.

Pharmacological treatment

  • TREAT WITH PLAN C (Young Infant Version - Page 41):
  • If IV Therapy Possible Immediately: Start IV fluid. Give 100 ml/kg Ringer's Lactate Solution (or Normal Saline). Give 30ml/kg in 1 hour, THEN 70ml/kg in 5 hours.
  • Reassess frequently (every hour initially). If hydration not improving, give IV drip faster.
  • Also give ORS (about 5 ml/kg/hour) by mouth/NG tube as soon as infant can take it.
  • Reassess dehydration status after 6 hours and choose appropriate plan (A, B, repeat C).
  • If IV Therapy Not Available/Possible:
  • If trained in NG tube insertion: Start rehydration by NG tube with ORS solution: give 20 ml/kg/hour for 6 hours (total 120 ml/kg). Reassess every 1-2 hours. If vomiting/distension, slow rate. If not improving after 3 hrs, refer urgently for IV.
  • If NG tube not possible AND infant can drink: Refer URGENTLY. Give mother ORS and show how to give frequent sips during the trip.
  • If infant also has another severe classification (e.g., PSBI): Refer URGENTLY after stabilizing airway/breathing and giving essential pre-referral treatments (e.g., antibiotic). Give frequent sips of ORS on the way if possible.

Pre-referral treatment

  • If referring urgently: Ensure airway is clear. Give frequent sips of ORS on the way if infant can drink. Keep infant warm (Page 40). Give other essential pre-referral treatments based on other classifications (e.g., antibiotic for PSBI - Page 40).

Follow-up

  • Managed initially under Plan C, then reassessed.
  • If discharged on Plan A or B, follow-up as per those plans.

Counselling points

  • Explain the seriousness of dehydration in a young baby and the need for urgent hospital treatment.
  • Show how to give ORS sips frequently during transport if applicable.
  • Advise on keeping infant warm.
  • Advise mother to continue breastfeeding whenever infant wants.

Differential diagnosis

  • Some Dehydration (Young Infant)
  • Septic shock
  • Other causes of altered consciousness/lethargy (PSBI, meningitis, hypoglycemia)

Complications

  • Hypovolemic shock
  • Acute kidney injury
  • Severe electrolyte imbalance
  • Seizures
  • Death

Prevention

  • Exclusive breastfeeding.
  • Handwashing.
  • Safe water/sanitation.
  • Rotavirus vaccination (where available, consider age limits).
  • Prompt management of diarrhoea with ORS and continued feeding.
