研究目的: |
虽然已有研究证实OSA患者在无痛内镜等操作中发生低氧的风险显著升高,但临床目前缺乏基于便携睡眠监测构建术中低氧预测模型的前瞻性研究。现有研究主要聚焦于AHI这一单一事件频率指标,忽视了患者间差异最大的低氧负荷特征(如ODI或CT90在不同AHI水平下波动范围大),对真实术中呼吸风险的预测不足,尤其在轻中度OSA人群及老年患者中更为明显。此外,目前尚未有研究系统评估上述气体交换参数与术中低氧事件、气道干预频率、丙泊酚剂量反应之间的关系,无法为临床制定个体化麻醉策略(如吸氧浓度、镇静深度控制、术中呼吸监测等级)提供量化依据。 本研究拟通过前瞻性收集术前便携式睡眠监测参数及围术期低氧血症相关数据,采用多元Logistic回归分析、ROC曲线绘制及亚组分析等统计学方法,构建术中低氧风险预测模型。研究将该模型与现有的OSA筛查工具(如STOP-Bang问卷、AHI指标)进行系统比较,以评估其在门诊无痛麻醉场景中的预测效能、实用性与推广潜力。我们假设,在接受无痛胃肠镜检查的患者中,术前便携式睡眠监测中获得的动态低氧负荷参数(如氧减指数ODI、血氧饱和度<90%的时间比例CT90、呼吸暂停低通气时间占比AHT%)与术中低氧事件的发生具有显著相关性,且其预测能力优于传统的问卷筛查方法与单一AHI指标。 |

Objectives of Study: |
Although existing studies have confirmed that patients with obstructive sleep apnea (OSA) face a significantly elevated risk of hypoxemia during procedures such as painless endoscopy, there is currently a lack of prospective research on constructing an intraoperative hypoxemia prediction model based on portable sleep monitoring in clinical practice. Most available studies have focused solely on the apnea-hypopnea index (AHI)—a metric reflecting event frequency—while neglecting hypoxic burden characteristics, which exhibit the greatest interindividual variability (e.g., oxygen desaturation index [ODI] and cumulative time with oxygen saturation < 90% [CT90] show wide fluctuations across different AHI levels). This deficiency results in inadequate prediction of actual intraoperative respiratory risks, particularly evident in patients with mild-to-moderate OSA and elderly populations. Furthermore, no studies have systematically evaluated the relationships among the aforementioned gas exchange parameters, intraoperative hypoxemic events, frequency of airway interventions, and propofol dose-response. Consequently, there is a lack of quantitative evidence to guide the formulation of individualized anesthetic strategies in clinical settings (e.g., oxygen concentration, sedation depth control, and intraoperative respiratory monitoring intensity). The present study aims to establish an intraoperative hypoxemia risk prediction model by prospectively collecting preoperative portable sleep monitoring parameters and perioperative hypoxemia-related data, followed by statistical analyses including multivariate logistic regression, receiver operating characteristic (ROC) curve plotting, and subgroup analysis. This model will be systematically compared with existing OSA screening tools (e.g., the STOP-Bang questionnaire and AHI) to evaluate its predictive efficacy, clinical utility, and scalability in the context of outpatient painless anesthesia. We hypothesize that in patients undergoing painless gastroenteroscopy, dynamic hypoxic burden parameters derived from preoperative portable sleep monitoring—including oxygen desaturation index (ODI), percentage of total sleep time with oxygen saturation < 90% (CT90), and apnea-hypopnea time ratio (AHT%)—are significantly correlated with the occurrence of intraoperative hypoxemic events, and that their predictive performance is superior to that of conventional questionnaire-based screening methods and the single AHI metric. |
