Transcript

Slide 1-

An approach to a child with respiratory symptoms Dr. Pushpa Raj Sharma Professor of Child Health Institute of Medicine
Slide 2-

Common respiratory symptoms Cough Runny nose Tachypnoea Snoring Stridor Wheeze Chest pain Chest indrawing Haemoptysis Bluish discoloration
Slide 3-

The most important sign: Tachypnea Cut off rate per minute Less than 1 week up to 2 months: 60 or more 2 months up to 12 months: 50 or more 12 months up to 5 years: 40 or more. Pathophysiology: Hypoxaemia Pulmonary oedema Parenchymal inflammation Restricitve/obstructive diseases
Slide 4-

The most severe sign: Apnoea Acute life threatening event: Apnoea > 20 second or associated with pallor, cyanosis, convulsion or limpness. Aetiology: Prematurity Sepsis Meningitis/encephalitis Drugs Abnormal muscle tone
Slide 5-

Cough Commonest respiratory symptom. Physiological to remove excess secretions or foreign body. Cough receptors in the posterior pharynx and large bronchi. Vagus/ glossopharyngeal: afferent to cough centre –pons /medulla. Efferent to - larynx/ diaphragm/ chest wall/abdominal wall/pelvic Acute: lasts less than 2 weeks. Chronic: lasts more than 2 weeks.
Slide 6-

Cough relating to time/ posture During or after feeding: aspiration Night: asthma/ post nasal drip Morning: bronchiectasis With exercise: asthma Absence during play: psychogenic Seasonal: allergen Cold: hyperreactivity
Slide 7-

Differential diagnosis of chronic cough Infants: Infections Chlamydia Pertussis Bronchiolitis Non infectious Asthma Domestic smoke pollution/passive smoke Gasro-eso. Reflux Foreign body Congenital anamolies Tracheo-eso. fistula Children Infectious Pneumonia Croup Post nasal drip/sinusitis Non infectious Asthma Foreign body Tropical eosiniphilia Environmental irritants Psychogenic
Slide 8-

Treatment of chronic cough Over the counter cold preparation: no beneficial effect in children under 5 years. Post nasal drip: Propped up position at 30 degree. Treat accordingly for Allergic/non allergic rhinitis; Sinusitis Macrolides: if Mycoplasma / chlamydia suspected. Nasal steroids/ decongestant Bronchodilators/ steroids Specific treatment
Slide 9-

Psychogenic Cough School aged children. The child is often a high achiever; family stress Fixed timing but disappears during sleep and when distracted. Diagnosis by observation and exclusion of other causes. Treatment: Counseling, Normal saline gargle
Slide 10-

Noisy Breathing Snoring Grunting Stridor Wheeze Ronchi
Slide 11-

Snoring Inspiratory harsh sound irregularly Associated with: large tonsils and adenoids; micrognathia, macroglossia, palatal palsy, pharyngeal hypotonia, obesity Diagnostic test: Sleep study, flexible bronchoscopy, lateral x-ray neck Treatment needed if: Sleeping difficulty; daytime somnolence, enuresis, growth failure, morning headache.
Slide 12-

Stridor Inspiratory harsh sound continuously. Can occur during expiration (intrathoracic) or both phase of respiration. Asses the severity Drooling of saliva, respiratory distress, unable to swallow, cyanosis Common causes: Infective: epiglottitis, laryngotracheobronchitis, tracheitis, retropharyngeal abscess (rare) Malignancy: tumor compression, papilloma Allergic: angioneurotic oedema. Congenital: laryngomalacia, laryngeal web, vascular ring, Aspiration: foreign body. Neuronal: paralysis of vocal cord. Investigation Blood count; Lateral neck X-ray; flexible bronchoscopy.
Slide 13-

Grunting Low pitched expiratory sound. Protective phenomenon to prevent collapse of alveoli: PEEP Causes: Respiratory distress syndrome Severe pneumonia, ARDS, severe sepsis Investigations: CXR; O2 saturation, blood gas
Slide 14-

A child who wheezes: All wheezes are not Asthma Cough could be the only symptom. Triggering factor Worse at night History of repeated problem. Symptomatic improvement with bronchodilator. Gastro-esophageal reflux: Prokinetic.
Slide 15-

Causes of Wheeze/Ronchi Bilateral Asthma Bronchiolitis Mycoplasma Cystic fibrosis Alpha 1 antitrypsin deficiency Severe pneumonia Unilateral Pneumonia Foreign body Mediastinal mass Tuberculosis Bronchiectasis Vascualr ring
Slide 16-

Chest Pain: Rarely cardiac origin in children. Infective Pneumonia; pleural effusion, pneumothorax. Born Holm disease Asthma Trauma Costochondritis Psychogenic Pericardial lesions
Slide 17-

The severe signs: Chest Indrawing and Cyanosis Chest in drawing: Increased airway resistance. Contraction of diaphragm and pulling of ribs inside. Negative pressure inside Breathing in and lower chest wall goes in. Supra sternal, inter costal recession. Cyanosis: Vasomotor instability in acrocyanosis. Defective perfusion. Defective ventilation. Defective diffusion. Methhaemoglobinemia Hyperoxia test
Slide 18-

Haemoptysis: not common Blood from posterior naso-pharynx or hematemesis: the difference. Aetiology: Bronchiectasis. Severe cough Pneumonia Paragonimiasis Foreign body Severe measles Haemangioma/ AV malformation
