Objective:
Necrotizing pneumonia (NP) is recently recognized as a complication of pneumonia. The data on NP are scant from developing world and we aimed to describe the characteristic features of NP in our children.
Study Design:
Single center retrospective cohort analysis.
Patient Selection:
Institutional database of children treated for pneumonia between September 2014 and May 2018 was searched to identify children with NP.
Methods:
The demographic characteristics, laboratory results, and clinical information were recorded for patients selected as NP and analyzed.
Results:
In total, 10 patients (3.7%) of NP were identified out of 272 patients with pneumonia. Median age was 3 years (range: 3 months to 12years). All cases had severe respiratory distress and 70% required mechanical ventilation and inotropic support. The causative pathogens were identified in 6/10 children (60%) with Staphylococcus aureus being most common (4/10). Pleural effusion and pneumothorax were seen in six cases. Four cases had bilateral pleural effusion and three had bilateral pneumothorax. Intercostal drainage (ICD) was placed in 70% and bilateral ICD was placed in 40% cases. Bronchopleural fistula (BPF) developed in two cases and one had bilateral BPF. Median [inter quartile range] ICD days and hospital stay were 9 (6-14) and 13.5 (7.5-18.5) days, respectively. Mean (±SD) total antibiotic (in hospital plus outpatient) days were 28.8 ± 9.6 days. Four cases had airway hemorrhage and in three cases this was massive and fatal.
Conclusion:
NP is a relatively rare but severe complication of pneumonia distinct from pediatric acute respiratory distress, pleural effusion and empyema. Airway hemorrhage is the most fatal complication.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
Pneumonia I: Introduction
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...
Pneumonia V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....
