This study evaluates the efficacy of various chest physiotherapy (CPT) techniques in treating pediatric patients with pneumonia, a leading cause of morbidity and mortality among children worldwide. Despite the widespread use of CPT, there is limited consensus on the most effective methods, prompting this comprehensive assessment. We conducted a randomized controlled trial involving 150 pediatric patients aged 0-18 years, diagnosed with pneumonia and admitted to a tertiary care center. Patients were randomly assigned to receive one of three CPT techniques: percussion, vibration, or postural drainage. The primary outcomes measured were improvements in respiratory function, including oxygen saturation levels and respiratory rates, and the duration of hospital stay. [1] Secondary outcomes included patient comfort and the incidence of adverse effects. The results demonstrated that percussion and vibration techniques significantly improved respiratory function compared to postural drainage, with marked increases in oxygen saturation and reductions in respiratory rates (p < 0.05). These techniques also resulted in shorter hospital stays, indicating faster recovery times. [3] Minimal and manageable adverse effects were observed, primarily associated with discomfort during the procedures. Our findings align with and extend previous research, providing robust evidence for the superior efficacy of percussion and vibration techniques in managing pediatric pneumonia. This study underscores the need for updated clinical guidelines to incorporate these effective CPT methods and recommends routine training for healthcare providers to ensure safe and proper administration.
