OBJECTIVE/BACKGROUND: Since the apnea-hypopnea index (AHI), which is used in the diagnosis and grading of OSAS, does not adequately reflect the clinical perspective of the disease, the Baveno classification of OSA was developed, which allows multicomponent evaluation of OSAS patients. The aim of our study was to evaluate the application of the Baveno classification in clinical practice.
PATIENTS/METHODS: A prospective study was performed on patients diagnosed with OSAS between January 2021 and June 2022. Patients were divided into 4 groups according to Baveno classification (Groups A-D) and three groups as mild, moderate, and severe OSAS according to AHI.
A total of 378 patients (70% male, mean age 48.68 ± 11.81 years) were included in the study. The patients had mild (n: 75; 20%), moderate (n: 88; 23%), and severe (n: 215; 57%) OSAS. According to Baveno classification, patients were included in Groups A (n: 90; 24%), B (n: 105 (28%), C (n: 65; 17%), and D (n: 118; 31%). The mean AHIs of the Baveno groups were similar ( = 0.116). Oxygen desaturation index (ODI) was higher in Groups B and D compared to Group A. The duration of T90 desaturation was longer in Groups C and D compared to Groups A and B ( < 0.05).
The Baveno classification divided our OSAS cases into equivalent groups. One out of every four patients with mild OSAS was in Group D. This data was noteworthy in that the Baveno classification allows for the identification of symptomatic and comorbid patients with mild OSAS according to AHI and for the application of more effective treatments to these patients. Patients with comorbidities experienced oxygen desaturation for a longer period of time at night, and oxygenation deteriorated in patients with prominent symptoms. Baveno classification was found to be a more reasonable and easily applicable approach in clinical practice.
目的/背景：由于用于诊断和分级 OSAS 的呼吸暂停-低通气指数 (AHI) 不能充分反映疾病的临床观点，因此开发了 Baveno 分类法来评估 OSAS 患者。我们研究的目的是评估 Baveno 分类在临床实践中的应用。
患者/方法：对 2021 年 1 月至 2022 年 6 月期间诊断为 OSAS 的患者进行前瞻性研究。根据 Baveno 分类（A、B、C 和 D 组）将患者分为 4 组，并根据 AHI 将患者分为三组：轻度、中度和重度 OSAS。
共有 378 名患者（70%为男性，平均年龄 48.68±11.81 岁）纳入研究。患者患有轻度（n=75；20%）、中度（n=88；23%）和重度（n=215；57%）OSAS。根据 Baveno 分类，患者被分为 A 组（n=90；24%）、B 组（n=105；28%）、C 组（n=65；17%）和 D 组（n=118；31%）。Baveno 组的平均 AHI 相似（ = 0.116）。与 A 组相比，B 组和 D 组的氧减指数（ODI）更高。与 A 组和 B 组相比，C 组和 D 组的 T90 去饱和时间更长（ < 0.05）。
Baveno 分类将我们的 OSAS 病例分为等效组。每四个轻度 OSAS 患者中就有一个在 D 组。这一数据值得注意，因为 Baveno 分类法根据 AHI 识别出有症状和合并症的轻度 OSAS 患者，并为这些患者应用更有效的治疗方法。合并症患者夜间的氧饱和度下降时间更长，症状明显的患者的氧合作用恶化。Baveno 分类在临床实践中被发现是一种更合理和易于应用的方法。
