Abstract
ObjectiveTo investigate the efficacy of electronic bronchoscope-assisted lavage in the treatment of children with acute lobar pneumonia, and its influence on respiratory mechanics, lung compliance and lung oxygenation.
MethodsA total of 300 children with acute lobar pneumonia treated in Zhoukou Central Hospital from January 2019 to December 2021 were selected as the research subjects, and they were divided into control group and observation group by random number table method, with 150 cases in each group. Patients in the control group were given conventional treatment, and patients in the observation group were treated by electronic bronchoscope-assisted lavage based on the treatment of the control group. The clinical efficacy, respiratory mechanics indexes including peak inspiratory pressure (PIP), resistance in airways (Raw) and work of breath (WOB), pulmonary compliance indexes including thoracic compliance (CTH), static lung compliance (Cs) and dynamic lung compliance (Cd), pulmonary oxygenation indexes including oxygenation index (OI), arterial partial pressure of oxygen/inspired fraction of oxygen (PaO2/FiO2) and arterial/alveolar partial pressure of oxygen (a/APO2) were compared between the two groups.
ResultsThe effective rate of the observation group (94.67%, 142/150) was higher than that of the control group (83.33%, 125/150), P<0.05. The symptom improvement time and hospitalization time in the observation group were shorter than those in the control group (all P<0.05). After treatment, PIP, Raw, WOB and OI in both groups were lower than those before treatment, while CTH, Cs, Cd, PaO2/FiO2 and a/APO2 were higher than those before treatment (all P<0.05); moreover, the PIP, Raw, WOB, OI in the observation group were lower than those in the control group, and CTH, Cs, Cd, PaO2/FiO2, a/APO2 were higher than those in the control group after treatment (all P<0.05).
ConclusionsElectronic bronchoscope-assisted lavage is effective in the treatment of children with acute lobar pneumonia. It can relieve the symptoms of children, improve respiratory mechanics and pulmonary oxygenation function, and improve pulmonary compliance.
