Introduction:
This study prospectively evaluated the effect of early bronchoalveolar lavage (BAL) on refractory Mycoplasma pneumoniae pneumonia with radiologically proven large pulmonary lesions in children.
Methods:
A total of 35 children diagnosed as having refractory M. pneumoniae pneumonia with radiologically proven large pulmonary lesions completed the study. According to the time point of BAL, they were divided into 2 groups. In the early BAL group, BAL was performed within 3 d after admission (n = 22); in the late BAL group, BAL was performed 3 d later after admission (n = 13). Clinical effects were compared between these 2 groups.
Results:
After BAL therapy, improvement in clinical symptoms and laboratory findings as well as resolution of pulmonary lesions on radiography were obtained in all subjects. The median fever duration after admission was 4 (2-7) d and 5 (2-10) d (P < .05), and the median hospitalization duration was 7 (5-10) d and 10 (5-14) d (P < .05), respectively, in the early BAL group and the late BAL group. Approximately 7 d after admission, 67% of subjects in the early BAL group showed resolution of atelectasis on x-ray image versus a corresponding rate of 14% in the late BAL group (P < .05). Furthermore, laboratory indices recovered quicker in the early BAL group than in the late BAL group (P < .01).
Conclusions:
BAL appeared to be efficacious and well-tolerated treatment for refractory M. pneumoniae pneumonia with radiologically proven large pulmonary lesions, and early application of BAL may be more beneficial.
Insights
Early bronchoalveolar lavage (BAL) significantly improved outcomes for children with refractory Mycoplasma pneumoniae pneumonia. This early intervention reduced fever duration and hospitalization, demonstrating its therapeutic benefit.
Area of Science:
- Pediatric Pulmonology
- Infectious Diseases
- Respiratory Medicine
Background:
- Refractory Mycoplasma pneumoniae pneumonia in children can present with large pulmonary lesions.
- Early diagnosis and intervention are crucial for managing severe pediatric respiratory infections.
Purpose of the Study:
- To evaluate the efficacy of early bronchoalveolar lavage (BAL) in children with refractory Mycoplasma pneumoniae pneumonia.
- To compare the clinical outcomes of early versus late BAL administration.
Main Methods:
- A prospective study involving 35 children with refractory M. pneumoniae pneumonia.
- Children were divided into an early BAL group (within 3 days) and a late BAL group (after 3 days).
- Clinical symptoms, laboratory findings, and radiological resolution were compared between groups.
Main Results:
- All patients showed improvement after BAL therapy.
- The early BAL group had significantly shorter median fever duration (4 days vs. 5 days) and hospitalization (7 days vs. 10 days).
- Early BAL led to quicker resolution of atelectasis (67% vs. 14%) and faster recovery of laboratory indices.
Conclusions:
- Bronchoalveolar lavage (BAL) is an effective and safe treatment for refractory M. pneumoniae pneumonia in children.
- Early application of BAL (within 3 days) appears more beneficial, leading to improved clinical and radiological outcomes.

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 V: Nursing management and Prevention
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
