Management of Severe Bronchopneumonia in Infants

Admission and Monitoring

The British Thoracic Society recommends immediate hospital admission with intravenous antibiotic therapy for infants with severe bronchopneumonia and high-risk features, such as vomiting, poor feeding, tachypnea, tachycardia, fever, and young age 1, 2, 3
The American Academy of Pediatrics suggests admitting infants to a general pediatric ward with continuous cardiorespiratory monitoring 4
Infants should be monitored for signs of deterioration, including increased work of breathing, apnea, grunting, and altered mental status 6

The British Thoracic Society recommends maintaining SpO2 >92% at all times, and initiating supplemental oxygen via nasal cannula if SpO2 drops <92% 1, 4, 5
Elevating the head of bed 30-45 degrees is recommended to improve respiratory status 4
Gentle nasal suctioning should be performed as needed, but chest physiotherapy should not be ordered as it is not beneficial 1, 3, 4

The British Thoracic Society explicitly states that IV antibiotics are indicated when the child is unable to absorb oral antibiotics due to vomiting or presents with severe signs 1, 3
The recommended primary regimen is ampicillin-sulbactam IV (or IV co-amoxiclav if available) plus azithromycin IV, to cover atypical organisms such as Mycoplasma and Chlamydia 1, 3, 4
Alternative regimens include cefuroxime IV or cefotaxime IV 1, 3

IV fluids should be administered at 80% of maintenance to prevent SIADH, with monitoring of serum electrolytes daily 1, 3, 4
Nasogastric tubes should be avoided if possible, as they can compromise breathing in infants with small nasal passages 1, 3
Infants should be initially kept NPO due to vomiting, then advanced to small frequent feeds as tolerated 2, 4

Blood culture should be performed before starting IV antibiotics, and complete blood count with differential should be monitored for trends 1, 5
Serum electrolytes, BUN, and creatinine should be monitored daily, with consideration of viral respiratory panel to guide management 1, 3, 4, 5

The minimum duration of IV antibiotics is 3 days, with transition to oral antibiotics when clinically improved, and total antibiotic duration of 7-10 days 4
Transition to oral co-amoxiclav plus oral azithromycin should occur when the infant is afebrile, tolerating oral intake, and has improved work of breathing 1, 4, 6

Infants can be discharged when they are afebrile for ≥24 hours, have SpO2 >92% on room air, normalized respiratory rate, decreased work of breathing, and are tolerating adequate oral intake, with reliable follow-up arranged within 48-72 hours 1, 4, 5
