BackgroundObstructive sleep apnea-hypopnea syndrome (OSAHS) is a common sleep-related respiratory disease. Despite reports of low-temperature plasma radiofrequency ablation of tonsils and adenoids for the treatment of OSAHS, the effects on lung function and quality of life are unclear.AimsThis study aims to explore the effects of low-temperature plasma treatment on pulmonary function in children with OSAHS.MethodsA total of 110 children with OSAHS were included in this prospective study. Low-temperature plasma radiofrequency treatment and routine surgical treatment were performed in group A and group B, respectively. Maximal voluntary ventilation (MVV), forced vital capacity (FVC), and total lung capacity (TLC) were measured. OSA-18 survey was used to evaluate the quality of life 1 year after operation.ResultsGroup A had significantly higher effective treatment rate (P < 0.05) and lower operative period, bleeding volume, visual analog score, pseudomembrane detachment time, and time required to feed after operation than group B (all P < 0.001). There were no significant difference in the incidence of postoperative complications between the groups and MVV, FVC, and TLC between the groups before and after operation (all P > 0.05), and the above indexes in both groups were significantly increased after operation (all P < 0.05). OSA-18 scores in group A were significantly lower than group B after operation (P < 0.001).ConclusionsLow-temperature plasma technique performed in OSAHS children has a good clinical effect, which can reduce the operation time, intraoperative blood loss, postoperative pain, pseudomembrane detachment time, hospitalization time, and improve pulmonary function and quality of life.
