Obstructive sleep apnea syndrome (OSAS) is an underdiagnosed condition that causes recurrent episodes of partial or total collapse of the upper airways during sleep. It is associated with perioperative pulmonary complications. The STOP-BANG is a screening tool for assessing patients at risk of OSAS. The aim of this study was to assess the prevalence of patients with OSAS during pre-anesthetic evaluation at a hospital and its correlation with predictors of ventilation and difficult airway.
This is an observational, cross-sectional study carried out from January 2022 to September 2023. The questionnaire comprised demographic data (age, weight, BMI, type of surgery, and anesthesia), the STOP-BANG, predictors of difficult orotracheal intubation (Mallampati, mouth opening, thyromental distance, cervical mobility, and upper lip bite test), and predictors of difficult ventilation through a facial mask (male sex, absence of teeth, presence of beard, obesity, and >55 years).
The study had the participation of 221 patients, of whom 121 presented with a STOP-BANG ≥3, with a prevalence of 54.2%. All patients undergoing bariatric surgeries presented STOP-BANG ≥3. No significant statistical relationships were found between predictors of difficult orotracheal intubation and STOP-BANG ≥3. However, significant statistical relationships were found in relation to predictors of difficult ventilation through the facial mask.
阻塞性睡眠呼吸暂停综合征（OSAS）是一种诊断不足的病症，它会导致睡眠期间上呼吸道部分或完全坍塌，从而引发反复发作。它与围手术期肺部并发症有关。STOP-BANG 是一种评估 OSAS 风险患者的筛查工具。本研究的目的是评估一家医院在麻醉前评估中 OSAS 患者的患病率，以及其与通气和困难气道预测因素的相关性。
这是一项从 2022 年 1 月至 2023 年 9 月进行的观察性、横断面研究。问卷包括人口统计学数据（年龄、体重、BMI、手术类型和麻醉类型）、STOP-BANG、经口气管插管困难预测因素（Mallampati、张口度、甲状软骨-下颌骨距离、颈椎活动度和上唇咬测试）和经面罩通气困难预测因素（男性、无牙、有胡须、肥胖和 >55 岁）。
该研究共有 221 名患者参与，其中 121 名患者的 STOP-BANG≥3，患病率为 54.2%。所有接受减重手术的患者的 STOP-BANG≥3。经口气管插管困难预测因素与 STOP-BANG≥3 之间无显著统计学关系。然而，在经面罩通气困难预测因素方面发现了显著的统计学关系。
