Management of Lower Respiratory Tract Infection in Children

Assessment of Severity and Need for Hospitalization

The British Thoracic Society recommends assessing for indicators requiring hospital admission, including oxygen saturation <92%, respiratory rate >50 breaths/min, difficulty breathing, grunting, signs of dehydration, or inability of family to provide appropriate observation 1, 2
Monitoring of vital signs, including heart rate, temperature, respiratory rate, oxygen saturation level, and respiratory pattern, is essential for managing LRTI in children 3
For patients managed at home, families need information on managing fever, preventing dehydration, and identifying signs of deterioration, as recommended by the British Thoracic Society 1

The British Thoracic Society recommends amoxicillin as the first-choice oral antibiotic for children under 5 years, as it is effective against the majority of pathogens causing CAP in this age group, well-tolerated, and cost-effective 1, 2
If there is no improvement after 48 hours on treatment, the child should be reviewed by a healthcare provider, according to the British Thoracic Society 1
Alternative antibiotics, such as co-amoxiclav, cefaclor, erythromycin, clarithromycin, and azithromycin, may be considered if amoxicillin is contraindicated, as recommended by the British Thoracic Society 1, 2
Treatment duration should typically be 5-7 days, although this guideline is from Praxis Medical Insights, it is still a relevant consideration 4

Providing adequate hydration is crucial, and if intravenous fluids are needed, they should be given at 80% of basal levels with monitoring of serum electrolytes, as recommended by the British Thoracic Society 3, 5
Using antipyretics and analgesics to keep the child comfortable and to help with coughing is essential, according to the British Thoracic Society 3
Maintaining oxygen saturation above 92% with supplemental oxygen via nasal cannulae, head box, or face mask if needed is vital, as recommended by the British Thoracic Society 1

For children on oxygen therapy, performing observations, including oxygen saturation at least every 4 hours, is necessary, according to the British Thoracic Society 3
For home management, educating parents to monitor for signs of deterioration, including increased work of breathing, inability to drink, or worsening symptoms, is crucial, as recommended by the British Thoracic Society 1
If the child remains pyrexial or unwell 48 hours after starting treatment, re-evaluation is necessary, according to the British Thoracic Society 1

Chest physiotherapy is not beneficial and should not be performed in children with pneumonia, as recommended by the British Thoracic Society 3, 5
Nasogastric tubes may compromise breathing and should be avoided in severely ill children; if necessary, use the smallest tube in the smallest nostril, according to the British Thoracic Society 3, 5
Considering the possibility of Mycoplasma pneumoniae, which becomes more prevalent in older children, and using macrolide antibiotics if mycoplasma is suspected, is essential, as recommended by the British Thoracic Society 1, 2

The child should be reviewed if deteriorating or if not improving after 48 hours on treatment, according to the British Thoracic Society 1
For recurrent LRTIs, considering evaluation for underlying conditions, such as immunodeficiencies, allergies, or anatomical abnormalities, is necessary, although this guideline is from Praxis Medical Insights, it is still a relevant consideration 6
