目的研究便携睡眠监测阻塞定位仪(AG)在悬雍垂腭咽成形术(UPPP)前评估中的临床价值。方法对经Friedman临床分期系统检查认为有UPPP适应证的21例成年阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者在术前2d内行AG检查。结果 1.AG能自动分析得出各项主要睡眠相关呼吸紊乱指标和阻塞模式;2.阻塞模式绝大多数为上部和下部联合阻塞,上部阻塞构成比大于50%的有16例(76.19%),下部阻塞构成比大于50%的有5例(23.81%)。3.AG判定的腭后区阻塞百分比与Friedman临床分期之间无明确相关性。结论 AG具有分析睡眠相关呼吸紊乱事件和判定上气道阻塞水平的双重功能,对选择UPPP手术患者有重大的指导意义。
Objective To investigate the clinical value of portable sleep monitoring and occlusion locator (AG) in pre-uvulopalatopharyngoplasty (UPPP) evaluation. Methods Twenty-one patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) who were considered to have UPPP indications on the Friedman clinical staging system were examined by AG within 2 days before surgery. Results 1.AAG can automatically analyze the major sleep-related respiratory disorders and obstructive modes.2. The majority of obstructive modes are upper and lower combined obstructions, with 16 cases (76.19%) with upper obstruction more than 50% , 5 cases (23.81%) were lower than 50%. 3.AG determined the percentage of obstruction of the palate area and Friedman clinical stage no clear correlation between. Conclusion AG has the dual function of analyzing sleep-related respiratory disorders and determining the level of upper airway obstruction, which is of great guiding significance for the patients with UPPP.
