Paediatric Respiratory Examination - OSCE Guide | Geeky Medics (2023)

Paediatrics is full of respiratory presentations and thus, respiratory examinations. This guide provides an overview of how to perform a paediatric respiratory examination in an OSCE setting.

It is important to be flexible when examining a child, adjusting your approach whilst taking into consideration the patient’s age, personality and how unwell they are.

Be opportunistic in your examination – taking advantage of periods of quiet to listen to the chest and open mouth yawns or cries to look at the throat. Remember, parents and carers can also be a great asset – helping to explain the next step in the examination and position the child as you need them. Work as a team!

Introduction

Wash your hands and don PPE if appropriate.

Introduce yourself to the parents and the child, including your name and role.

Confirm the child’s name and date of birth.

Briefly explain what the examination will involve using patient-friendly language: “Today I’d like to perform a respiratory examination, which will involve observing your child, feeling their pulse and listening to their breathing with my stethoscope.”

Gain consent from the parents/carers and/or child before proceeding: “Are you happy for me to carry out the examination?”

General inspection

Appearance and behaviour

Observe the child in their environment (e.g. waiting room, hospital bed) and take note of their appearance and behaviour:

• Activity/alertness: note if the child appears alert and engaged, or quiet and listless.
• Cyanosis: bluish discolouration of the skin due to poor circulation (e.g. peripheral vasoconstriction secondary to hypovolaemia) or inadequate oxygenation of the blood (e.g. right-to-left cardiac shunting).
• Shortness of breath: may indicate underlying cardiovascular (e.g. congenital heart disease) or respiratory disease (e.g. asthma).
• Pallor: a pale colour of the skin that can suggest underlying anaemia (e.g. blood dyscrasia, chronic disease) or poor perfusion (e.g. congestive cardiac failure).
• Weight: note if the child appears a healthy weight for their age and height.

Syndromic features

Pay attention to features that may indicate the presence of an underlying genetic condition:

• Stature (e.g. tall/short)
• Syndromic facial features

See the end of this guide for a non-exhaustive list of clinical syndromes which can be associated with respiratory system pathology.

Sounds

Note any audible sounds as you observe the child and consider what underlying pathology they may indicate:

• Cough with wheeze: asthma, viral-induced wheeze
• Productive cough: lower respiratory tract infection
• Barking cough: croup, laryngomalacia
• Dry cough: allergies, tuberculosis
• Hoarse voice: laryngitis
• Hot potato voice: peritonsillar abscess
• Acute stridor: croup, foreign body, bacterial tracheitis, epiglottitis
• Chronic stridor: laryngomalacia, subglottic stenosis

Equipment

Observe for any equipment in the child’s immediate surroundings and consider why this might be relevant to the respiratory system:

• Mobility aids: neuromuscular disorder
• Feeding tubes (NG/NJ/gastrostomy): ex-premature infant, cystic fibrosis
• Oxygen saturation monitor or oxygen cylinder: chronic lung disease
• Tracheostomy: upper airway obstruction – each child in the UK should have a box of emergency tracheostomy equipment (often blue/red in colour). See our tracheostomy overview guide.

Medications

Note any medications by the bedside or in the child’s room and consider what underlying diagnoses they may indicate:

• Antibiotics: pneumonia, bronchiectasis, cystic fibrosis
• Inhalers: asthma
• Pancreatic enzymes: cystic fibrosis

Hands

Thehandscan provide lots of clinically relevant information and therefore a focused, structured assessment is essential.

Inspect the hands

General observations

Inspect the handsfor clinical signs relevant to the cardiovascular system:

• Colour:pallor suggests poor peripheral perfusion (e.g. congestive heart failure) and cyanosis may indicate underlying hypoxaemia.
• Tremor: may be caused by beta 2 agonist use (e.g. salbutamol).
• Eczema:increased likelihood of asthma and hayfever (atopy).

Finger clubbing

Finger clubbing involves uniform soft tissue swelling of theterminalphalanxof adigitwith subsequentloss of the normal anglebetween thenailand thenail bed. Finger clubbing is associated with several underlying disease processes, but those most likely to appear in a respiratory OSCE station include bronchiectasis, cystic fibrosis and primary ciliary dyskinesia.

To assess for finger clubbing:

• Ask the child to copy you in placing the nailsof their index fingers back to back.
• In a healthy individual, you should be able to observe asmall diamond-shaped window(known asSchamroth’s window).
• When finger clubbing develops, thiswindow is lost.
• If the child is too young for this to be possible, you can simply inspect the fingers, looking for soft tissue swelling of the terminal phalanx of the digits.

Pulse

Radial pulse

Palpate the child’s radial pulse, located at the radial side of the wrist, with thetipsof yourindexandmiddle fingersaligned longitudinally over the course of the artery.

Once you have located the radial pulse, assess therateandrhythm.

In babies, assess the femoral pulse instead.

Heart rate

Assessingheart rate:

• You can calculate the heart rate in a number of ways, including measuring for 60 seconds, measuring for 30 seconds and multiplying by 2 or measuring for 15 seconds and multiplying by 4.
• Forirregular rhythms, you should measure the pulse for afull 60 secondsto improve accuracy.

Face

Observe the child’s facial complexion and features, including their eyes, ears, nose, mouth and throat.

General appearance

Inspect the general appearance of the child’s face for signs relevant to the respiratory system:

• Nasal flaring/grunting: indicative of increased work of breathing.
• Micrognathia (undersized jaw): associated with a wide range of genetic syndromes (e.g. Pierre Robin, Noonan, Marfan).

Eyes

Inspect the eyes for signs relevant to the respiratory system:

• Conjunctival pallor: suggestive of underlying anaemia. Gently pull down their lower eyelid to inspect the conjunctiva.

Ears

Inspect the ears for signs relevant to the respiratory system:

• Tympanic membrane:may be inflamed or bulging in the context of acute otitis media which often accompanies viral upper respiratory tract infections.
• Hearing aids: hearing loss is associated with primary ciliary dyskinesia.

Nose

Inspect the nose for signs relevant to the respiratory system:

• Deviated nasal septum:may contribute to breathing difficulties.
• Nasal polyps: associated with atopy and cystic fibrosis.

Mouth

Inspect the mouth for signs relevant to the respiratory system (tip – ask the child to see how long their tongue is or how big their mouth is):

• Central cyanosis: bluish discolouration of the lips and/or the tongue associated with hypoxaemia (e.g. persistent pulmonary hypertension, bronchospasm, lower respiratory tract infection).
• Cleft palate:the full palate should be examined by visual inspection.

Throat

Inspect the throatfor signs relevant to the respiratory system:

• Inspect the throat using a pen torch and tongue depressor (this is often best left until the end of the examination of young children, as it is likely to upset them).
• Tonsillar hypertrophy: may indicate a history of recurrent tonsillitis and airway obstruction.

Tracheal position

Inspect the position of the trachea, which should becentral in healthy children.

Close inspection of the chest

Ask the parent or child (if appropriate) to expose the child’s chest.

Observe the chest, paying particular attention to the respiratory rate and work of breathing.

Closely inspect the anterior chest

Look for clinical signs that may provide clues as to the child’s past medical/surgical history:

• Scars suggestive of previous thoracic surgery: see the thoracic scars section below.
• Pectus excavatum: a caved-in or sunken appearance of the chest (e.g. Marfan syndrome).
• Pectus carinatum: protrusion of the sternum and ribs (e.g. Noonan syndrome).
• Asymmetry of chest wall movement: may indicate underlying pneumothorax or consolidation.
• Harrison’s sulcus (indrawing of the chest wall from long term diaphragmatic tug): associated with poorly controlled asthma.
• Chest hyper-expansion (barrel chest): can be associated with asthma and chronic respiratory obstruction.

Respiratory rate

Assess the child’s respiratory rate for 60 seconds to calculate the number of breaths per minute:

• Note anyasymmetriesin theexpiratoryandinspiratory phases of respiration (e.g. the expiratory phase is often prolonged in asthma exacerbations).
• The range of a normal respiratory rate varies significantly depending on the age of the child, so make sure to take this into account.

Work of breathing

Assess for signs of increased work of breathing.

General signs of increased work of breathing:

• Difficulty speaking (or feeding)
• Expiratory grunting (increasing positive end-expiratory pressure)

Recession:

• Tracheal tug
• Supraclavicular recession
• Intercostal recession
• Subcostal recession

Use of accessory muscles:

• Nasal flaring
• Abdominal breathing
• Head bobbing (secondary to sternocleidomastoid contractions)

Palpation of the chest

Palpate the apex beat

Palpate the apex beat with your fingers placed horizontally across the chest.

In healthy individuals, it is typically located in the5th intercostal spacein themidclavicular line.

Assess chest expansion

1.Place your hands on the child’s chest, inferior to the nipples.

2.Wrap your fingers around either side of the chest.

3.Bring your thumbs together in the midline, so that they touch.

4. Observe the movement of your thumbs (in healthy individuals they should move symmetrically upwards/outwards during inspiration and symmetrically downwards/inwards during expiration).

Reduced movement of one of your thumbs indicates reduced chest expansion on that side.

Percussion of the chest

Percussion of the chest involves listening to the volume and pitch of percussion notes across the chest to identify underlying pathology. Correct technique is essential to generating effective percussion notes.

Warn the child before beginning percussion – ‘I’m going to play your chest like a drum!’

Perform percussion gently, comparing one side to the other.

Percussion is often not performed on younger children.

Percussion technique

1. Place your non-dominant hand on the child’s chest wall.

2. Position your middle finger over the area you want to percuss, firmly pressed against the chest wall.

3. With your dominant hand’s middle finger, strike the middle phalanx of your non-dominant hand’s middle finger using a swinging movement of the wrist.

4. The striking finger should be removed quickly, otherwise, you may muffle the resulting percussion note.

Areas to percuss

Percuss the following areas of the chest, comparing side to side as you progress (see image example below):

• Supraclavicular region: lung apices
• Infraclavicular region
• Chest wall: percuss over 3-4 locations bilaterally
• Axilla

Auscultation

Start by showing the child your stethoscope and demonstrate it on your own chest and/or on one of their toys to familiarise them with this piece of equipment.

Suggest listening to their chest, making sure the stethoscope diaphragm isn’t cold prior to it making contact with the child.

When auscultating the chest, it is important that you have a systematic approach that allows you to compare each area on both the left and the right as you progress.

Technique

1. Ask the child to take ‘big breaths’ – some abnormal sounds may be inaudible if taking shallow breaths.

2. Position the diaphragm of the stethoscope over each of the relevant locations on the chest wall to ensure all lung regions have been assessed and listen to the breathing sounds during inspiration and expiration. Assess the quality and volume of breath sounds and note any added sounds.

3. Auscultate each side of the chest at each location to allow for direct comparison and increased sensitivity at detecting local abnormalities.

Assess vocal resonance

Assessing vocal resonance in an adult involves auscultating over different areas of the chest wall whilst the patient repeats a word or number consistently. The presence of increased tissue density or fluid affects the volume at which the patient’s speech is transmitted to the diaphragm of the stethoscope.

Vocal resonance may be difficult/impossible to assess in small children and therefore it is often not performed in this context. We have included further details on how to assess and interpret vocal resonance below.

Technique

1.Ask the child to say “99” or some other word every time you listen to their chest.

2.Auscultate all major regions of the anterior chest wall, comparing each side at each location.

Lymph nodes

Inspect for any evidence of obvious lymphadenopathy affecting the neck.

Palpate the lymph nodes

1. Position yourself behind the child and use both hands to start palpating the neck.

2. Use the pads of the second, third and fourth fingers to press and roll the lymph nodes over the surrounding tissue to assess the various characteristics of the lymph nodes. By using both hands (one for each side) you can note any asymmetry in size, consistency and mobility of lymph nodes.

3. Start in the submental area and progress through the various lymph node chains. Any order of examination can be used, but a systematic approach will ensure no areas are missed:

• Submental
• Submandibular
• Pre-auricular
• Post-auricular
• Superficial cervical
• Deep cervical
• Posterior cervical
• Supraclavicular

Take caution when examining the anterior cervical chain that you do not compromise cerebral blood flow (due to carotid artery compression). It may be best to examine one side at a time here.

A common mistake is a “piano-playing” or “spider’s legs” technique with the fingertips over the skin rather than correctly using the pads of the second, third and fourth fingers to press and roll the lymph nodes over the surrounding tissue.

Posterior chest assessment

Assess the posterior chest including inspection, chest expansion, percussion, vocal resonance and auscultation.

Allocate adequate time to assessing the posterior aspect of the chest as this is where you are most likely to identify clinical signs.

Final steps

Assess for evidence of oedema:

• Ask the parents if the child looks puffy or swollen.
• Inspect the limbs, sacral area and face: affected areas will depend on the age of the child and mobility status.

To complete the examination…

Explain to the child and parents that the examination is now finished.

Ensure the child is re-dressed after the examination.

Thank the child and parents for their time.

Explain your findings to the parents.

Ask if the parents and child (if appropriate) have any questions.

Dispose of PPE appropriately and wash your hands.

Summarise your findings to the examiner.

Further assessments and investigations

Suggest further assessments and investigations to the examiner:

• Cardiovascular examination: if concerned about cardiac pathology (e.g. heart failure with secondary pulmonary oedema).
• Inhaler technique assessment: if asthmatic and concerned about long term management.
• Record a full set of vital signs
• Assess peak expiratory flow rate: if asthmatic to assess response to treatment.
• Send a sputum sample for culture: if concerned about possible pneumonia.
• Plot the height and weight of the child on a growth chart
• Venous blood gas: if concerned about respiratory failure.
• Chest X-ray: if concerned about consolidation or pneumothorax.
