Abstract
Objective: To evaluate the clinical efficacy of high-frequency chest wall oscillation (HFCWO) as adjunctive therapy for pediatric pneumonia complicated by pulmonary consolidation. Methods: This retrospective study included 185 pediatric patients, assigned to a treatment group (n=112, receiving HFCWO plus standard therapy) or a control group (n=73, receiving standard therapy alone). Outcomes assessed included time to resolution of pulmonary rales, radiographic improvement, length of hospital stay, and rate of fiberoptic bronchoscopy lavage. Results: Compared with the control group, the treatment group showed significantly shorter time to rale resolution (5 days [IQR: 4-6] vs. 8 days [IQR: 6.5-9], P<0.05), higher radiographic improvement rate (87.5% vs. 74.0%, P<0.05), shorter hospital stay (9 days [IQR: 7-10] vs. 11 days [IQR: 9.5-13], P<0.05), and lower bronchoscopy lavage rate (12.5% vs. 26.0%, P<0.05). Conclusion: HFCWO as adjunctive therapy facilitates recovery in children with pneumonia and pulmonary consolidation, offering meaningful clinical benefit.
