obstructive Sleep Apnea Syndrome (OSAS) is a serious confition that compromises the quality of life and survival of patients. Its main risk fator in adults is obesity and the gold standard test for diagnosis is polysomnography (PSG), mainly through the apneia-hypopnea index (AHI). Objective: to analyze the sleep pattern of obese patients with indication for bariatric surgery, determining the main polisomnographic parameters compromised by obesity.
This work is a cross-sectional study with analysis of polysomnography perfomed in patients with obesity in the peroperative period of bariatric surgery at a clinic in Vitória da Conquista/BA during 2017. The Epi Info 7 platform was used for analysis of the data.
58 polysomnographic reports were analyzed, with 56,9% morbdly obese and 43,1% non-morbid. The prevalence of OSAS was 70,68% and de AHI ranged from zero to 84,6 with a mean of 19,47±22,89 e/h. morbidly obese, compared to "non-morbid", had a longer saturation time below 80% and 90% (0,4±0,93 vs. 0,12±0,45 e 4,87±7,38 vs. 1,36±2,87 respectively; p-value=0,02 in both), worse index respiratory disorders ((29,24±25,36 vs. 16,88±16,21; p-value=0,02), higher AHI (24,71±25,68 vs. 12,56±16,67; p-value=0,02), higher hypopnea index values (16,41±17,10 vs. 6,99±8,52; p-value=0,006) and lower minimum saturation (78,24±9,80 vs. 85,24±6,33; p-value=0,004).
the high prevalence of OSAS found confirms its indication in the preoperative period of bariatric surgery. The main respiratory event involved in most individuals with OSAS was the hypopnea index.
阻塞性睡眠呼吸暂停综合征（OSAS）是一种严重影响患者生活质量和生存的疾病。成人的主要危险因素是肥胖，诊断的金标准测试是多导睡眠图（PSG），主要通过呼吸暂停-低通气指数（AHI）。目的：分析肥胖患者的睡眠模式，确定肥胖引起的主要多导睡眠图参数。
这是一项横断面研究，分析了 2017 年在巴伊亚州维多利亚达孔基斯塔的一家诊所进行减肥手术围手术期肥胖患者的多导睡眠图。使用 Epi Info 7 平台分析数据。
分析了 58 份多导睡眠图报告，其中 56.9%为病态肥胖，43.1%为非病态肥胖。OSAS 的患病率为 70.68%，AHI 从 0 到 84.6 不等，平均值为 19.47±22.89 次/小时。病态肥胖患者与“非病态肥胖”患者相比，80%和 90%的饱和度时间更长（0.4±0.93 对 0.12±0.45 分别为 4.87±7.38 对 1.36±2.87；p 值均为 0.02），呼吸障碍指数（29.24±25.36 对 16.88±16.21；p 值均为 0.02）、更高的 AHI（24.71±25.68 对 12.56±16.67；p 值均为 0.02）、更高的呼吸暂停低通气指数（16.41±17.10 对 6.99±8.52；p 值均为 0.006）和更低的最低饱和度（78.24±9.80 对 85.24±6.33；p 值均为 0.004）。
肥胖患者术前 OSAS 发生率高，证实了其在减肥手术前的适应证。大多数 OSAS 患者的主要呼吸事件是呼吸暂停低通气指数。
