Q

Define Sepsis.

A
  • Systemic inflammatory response syndrome = generalised inflammatory response, defined by the presence of ≥2 criteria (abnormal temperature or WCC must be one of the criteria):
    • Abnormal core temperature (<36 or >38.5°C)
    • Abnormal HR (>2 S.D. above normal for age, or less than 10th centile for age if child aged < 1 years)
    • Raised RR (>2 S.D. above normal for age, or mechanical ventilation for acute lung disease)
    • Abnormal WCC in circulating blood (above or below normal range for age, or >10% immature cells)

Q

Describe the neonatal resuscitation guidelines.

A
  1. Dry baby

  3. Within 60s if not breathing = open airway → 5 inflation breaths
    1. Reassess = if no increase in HR, look for chest movement → if chest NOT moving → re-check head position, suction airway, other airway manoeuvres → repeat 5 inflation breaths, check for chest movement
    2. Reassess → repeat 5 inflation breaths until chest movement seen
  4. Chest moves, HR slow (<60bpm) and ventilate for 30s [rate: 15 over 30s]
  5. Chest moves, HR slow (<60bpm), Chest compressions + ventilation
  6. Reassess HR every 30s: if HR not detectable/slow (<60bpm), consider venous access and drugs
    1. NaCl (fluid resuscitation)

    4. NaHCO3 (for metabolic acidosis)
