Respiratory Distress in Paediatrics: Causes, Indicators and Early Management. My name is Hannah Bellsham-Revell. I'm a Paediatric Cardiologist at Evelina London Children's Hospital.

Signs of respiratory distress. Use of accessory muscles, so working hard, is a sign of respiratory distress. This can include nasal flaring, tracheal tug, intercostal and subcostal recession, use of shoulder muscles and grunting, otherwise known as auto-PEEP.

Clinical evaluation. End of the bed. What can you see? Is the patient using accessory muscles? What is the respiratory rate? Are there added noises? Like wheeze, which is expiratory or stridor, which is inspiratory. What can you feel? Crepitations, chest wall motion. What can you hear? Crackles, crepitations, wheeze or stridor.

Common conditions in paediatrics. Bronchiolitis. This is small airway inflammation usually presents under 1-2 years of age with crackles and wheeze, wet spluttery cough, prolonged exhalation often with coryza and then maybe patchy changes on the chest X-ray. Heart failure. This can present at any age, and may or may not have a murmur. Breathlessness, maybe crackles, and other adult signs, although in smaller children, hepatomegaly, pulmonary oedema on chest X-ray with an increased heart size may be of more use.
1:25
Chest infection or pneumonia. Fever with a cough, possible chest X-ray changes and focal chest signs may point towards a chest infection or pneumonia. Asthma is associated with wheeze, prolonged expiratory phase and may or may not have an intercurrent infection. Croup presents with stridor and respiratory distress. Foreign body inhalation may present with stridor or wheeze, depending on where the foreign body gets stuck. It is important to note that in asthma, croup and foreign body inhalation, desaturation is a late sign. If you have a patient who is already desaturated, that is a worrying sign. Early management. ABC approach.
