Effect of an airway clearance technique in the treatment of children with severe pneumonia.

This was a research study, mainly explored the effect of an airway clearance technique (ACT) in treating children with severe pneumonia. One hundred children with severe pneumonia who accepted therapy in Shulan (Hangzhou) Hospital Affiliated to Zhejiang Shuren University Shulan International Medical College from January 2023 to January 2024 were selected and randomly divided into a control group and observation group. The control group accepted anti-inflammatory, cough, phlegm and asthma treatment, while the observation group accepted ACT therapy including anti-inflammatory, cough, phlegm, and asthma treatment. As compared to the control group, the observation group presented better total effective rate, shorter cough and sputum relief time, defervescence time, length of hospital stay, lung rale and disappeareance time, and lung shadow disappearance time. The observation group also had higher peak expiratory flow (PEF), forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) levels, higher cough reflex, secretion viscosity and secretion volume scores, higher arterial oxygen pressure (PaO2) and arterial oxygen saturation (SaO2) levels as well as lower levels of inflammatory markers. We conclude that, the clinical efficacy of ACT for treatment of children with severe pneumonia is remarkable, which can improve related symptoms, improve lung function and blood gas indices, repress inflammation, and promote airway recovery..
