睡眠监测设备负荷对阻塞性睡眠呼吸暂停低通气综合征诊断的影响

目的　评价睡眠监测设备负荷变化对监测结果的影响。方法　对50例受试者分别进行采用连线较少且允许患者活动度较大的II类便携式睡眠监测（portable monitor,PM）设备及传统多道睡眠图（PSG）监测。对比两者的主观评价及客观监测结果的差异,分析差异产生的原因。结果　50例受试者中,29例为OSAHS患者,21例为对照组,其中无鼾症者14例,单纯鼾症7例。PSG监测的呼吸暂停低通气指数（AHI-PSG）与PM设备的AHI值（AHI-PM）呈正相关（r =0.914,P <0.001）。PM与PSG诊断一致性和分度一致性的κ 值分别为0.919和0.658（P 均＜0.05）。PSG-AHI≥5次/h时,AHI-PM的ROC曲线下面积（AUC）为0.987,相对应的最佳诊断切点为4.26次/h,此时敏感度为96.6%,特异度为95.2%,均表现出良好一致性。在对照组,PM和PSG检测到的AHI值无明显相关性（1.52次/h vs 1.68次/h,P＞0.05）,在OSAHS组,PM较PSG监测到的AHI偏低（18.6次/h vs26.6次/h,P＜0.05）。N3期睡眠时间占总睡眠时间的百分比,PM较PSG更高（21.8% vs 13.5%,t =-5.505,P＜0.05）,PM较PSG的仰卧位睡眠时间差异无统计学意义（62.5% vs56.3%,P＞0.05）。结论　与PSG相比,PM的负荷小,舒适度和接受程度较高,OSAHS患者用负荷较低的PM检测到的AHI值更低,可能与睡眠质量提升有关。     

阻塞性睡眠呼吸暂停低通气综合征患者睡眠参数与白天嗜睡、睡眠质量及体质量指数的相关性研究

目的研究阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者睡眠监测指标与白天嗜睡、睡眠质量、体质量指数(BMI)的相关性。方法选取2020年4月至2021年2月以睡眠打鼾、呼吸暂停为主要症状就诊于苏北人民医院耳鼻咽喉头颈外科318例患者作为研究对象,分别进行Epworth嗜睡量表(Epworth sleeping scale,ESS)评分、匹兹堡睡眠质量指数(Pittsburgh sleep quality index,PSQI)评分和多道睡眠图(PSG)监测,整理数据后筛选出符合要求者216例。根据睡眠监测结果将研究对象分为对照组25例(AHI<5次/h)、轻度OSAHS组52例(5次/h≤AHI<15次/h)、中度OSAHS组48例(15次/h≤AHI<30次/h)、重度OSAHS组91例(AHI≥30次/h)。比较各组PSG相关指标、ESS总分、PSQI总分及BMI,利用Pearson相关分析,探讨ESS总分、PSQI总分、BMI与PSG指标相关性。结果①各组体位改变次数、俯卧位呼吸暂停低通气次数差异无统计学意义,其余各项PSG研究指标差异均有统计学意义(P<0.05);②四组受试者ESS总分和BMI差异有统计学意义,PSQI总分差异无统计学意义;③AHI、ODI、体位改变次数与ESS总分呈正相关(r=0.272、0.287、0.141,P<0.01),平均血氧饱和度(average oxygen saturation,ASaO_(2))、最低血氧饱和度(lowest oxygen saturation,LSaO_(2))与ESS总分呈负相关(r=-0.333、-0.299,P<0.01),平均心率(average heart rate,AHR)与ESS总分无显著相关性(r=0.009,P=0.894);AHI、ODI与BMI呈正相关(r=0.317、0.363,P<0.01),ASaO_(2)、LSaO_(2)与BMI呈负相关(r=-0.273、-0.271,P<0.01),体位改变次数、AHR与BMI无显著相关性(r=0.055、0.038,P=0.422、0.574);PSQI总分与所研究的PSG指标无显著相关性。结论ESS和BMI均能在各自层面反映OSAHS严重程度。AHI、ODI越高,LSaO_(2)、ASaO_(2)越低,则ESS总分越高,BMI越大,OSAHS越严重;夜间体位改变次数越多,ESS总分越高,患者白天嗜睡越严重。虽然PSQI总分与PSG监测指标无明显相关性,但可反映OSAHS患者的精神和心理状态,大部分患者带有抑郁或焦虑情绪,造成OSAHS患者不良预后。三者联合可作为OSAHS的初筛,评估其严重程度,为早期干预、改善预后提供依据。     

体位改变对阻塞性睡眠呼吸暂停低通气综合征患者睡眠结构和呼吸事件的影响

Correlation of soft palate length with velum obstruction and severity of obstructive sleep apnea syndrome

Objective

Our aim in this study was to analyze whether soft palate length and velum obstruction during sleep are correlated and to determine the effects of related parameters on obstructive sleep apnea syndrome (OSAS) severity. We used computed tomography to measure soft palate length and drug-induced sleep endoscopy (DISE) to evaluate velum obstruction severity. Patients also underwent polysomnography (PSG) for evaluation of OSAS severity.

Tongue-base suspension in conjunction with uvulopalatopharyngoplasty for treatment of severe obstructive sleep apnea: long-term follow-up results

OBJECTIVES/HYPOTHESIS: To evaluate the usefulness of tongue-base suspension (TBS) in addition to uvulopalatopharyngoplasty (UPPP) in the treatment of obstructive sleep apnea syndrome (OSAS). STUDY DESIGN: Long-term prospective case series. SETTING: University tertiary care medical center. METHODS: Fifty-five consecutive patients with severe OSAS (apnea-hypopnea index [AHI] 52.8+/-14.9 events/hr) with multilevel upper airway obstruction who refused treatment with continuous positive airway pressure underwent UPPP plus TBS with the Repose system. All patients were evaluated before surgery by clinical history, Epworth Sleepiness Scale (ESS), fiberoptic nasopharyngoscopy with Müller maneuver, and nocturnal polysomnography (PSG). After 3 years of surgery, all patients were re-evaluated at the clinic and had ESS test and full PSG. Surgical success was defined when the ESS dropped bellow 11, and the AHI decreased below the threshold of 20 events per hour of sleep and at least 50% from the preoperative value RESULTS: There were 42 (78%) patients in which the AHI score decreased more than 50%, the AHI was lower than 20 events/hr in the PSG, and the ESS was lower than 11 after 3-years of follow-up (surgical success index). Logistic regression analysis demonstrated that body mass index at baseline was the only variable with significant statistical power to predict surgical success (odds ratio 0.85; 0.73-0.95, 95% confidence interval, P<.01) CONCLUSION: When associated with UPPP, the TBS technique performed with the Repose system demonstrates a surgical success of up to 78% for patients with severe OSA who refused nasal continuous positive airway pressure.     

Polygraphic characteristics of upper airway resistance syndrome]

OBJECTIVE: (1) To analyze upper airway resistance syndrome (UARS) patients' polysomnographic characteristics, to lower the misdianosis of UARS. (2) To improve the understanding of UARS. METHODS: (1) Select 12 UARS patients diagnosed by PSG and continuous esophageal pressure measurement, the sleep structure, arousal index, apnea hyponea index (AHI) were analyzed, the body mass index (BMI), epworth sleepiness scale (ESS) were calculated. (2) Select 16 simple snoring cases as the control group, obstructive sleep apnea syndrome (OSAS) and UARS were ruled out by PSG and continuous esophageal pressure measurement for this group of cases. (3) Compare the 2 groups' first night PSG indexes (4) Compare the 2 nights PSG indexes of the UARS group, to see the continuous esophageal pressure measurement effects on their sleep. RESULTS: (1) There are no statistical difference of the 2 group's BMI and AHI. (2) Compared with the control group, UARS patients got higher arousal index and ESS score, more sleep stage 1 and stage 2, less sleep stage 3 and stage 4. (3) The 2 nights PSG indexes of UARS patients are not statistically different. CONCLUSIONS: (1) Compared with simple snoring cases, the UARS patients have some special characteristics, i.e., higher arousal index, less deep sleep, and higher ESS score, combined with the clinical manifestations, it is possible to screen UARS patients. (2) No evident effects of continuous esophageal pressure measurement on UARS patients sleep.     

Correlation of the Epworth Sleepiness Scale with respiratory sleep parameters in patients with sleep-related breathing disorders and upper airway pathology

The aim of the study was to test whether a correlation between the Epworth Sleepiness Scale (ESS) and respiratory sleep parameters recorded by polysomnography (PSG) in patients with sleep-related breathing disorders and upper airway pathology exists. The PSG records of 130 patients (average age 52.6 ± 10.7 years) with upper airway pathology suspected of having obstructive sleep apnea (OSA) have been retrospectively evaluated. Upper airway pathology included deviation of the nasal septum, inferior nasal turbinate hypertrophy, soft palate webbing, elongated uvula, tonsillar hypertrophy, macroglossia, hypertrophy of the tongue base, unfavorable palate position relative to the tongue base. To test for a possible correlation in this patient population between ESS score and arithmetic values of AHI, SPO₂, ODI and Arousal Index, the Spearman’s correlation coefficient was calculated. No correlation between ESS and AHI, minimal SpO₂ and ODI was proven and only a weak positive correlation between Arousal Index and ESS was found in this particular patient population. We concluded that in patients with upper airway pathology, it is not possible to predict solely on the basis of the ESS score the existence of OSA or of other disturbances in Arousal Index, minimal SpO₂ and ODI. Nevertheless, historical data evaluated by questionnaires, such as the ESS provide for additional information combined with the clinical findings to select patients who are candidates for further detailed sleep studies.     

Obstructive Sleep Apnea Syndrome: A Comparison Between Far‐East Asian and White Men

Objectives To investigate the possible differences between Far‐East Asian men and white men in obstructive sleep apnea syndrome (OSAS). Study Design Prospective nonrandomized controlled study. Methods This study compared consecutive Far‐East Asian men with OSAS (n = 50) with two selected groups of White men with OSAS (n = 50 in each group). One group of white men was controlled for age, respiratory disturbance index (RDI), and minimum oxygenation saturation (LSAT). Another group was controlled for age and body mass index (BMI). Cephalometric analysis was performed on all subjects. Results The majority of the Far‐East Asian men were found to be nonobese (mean BMI, 26.7 ± 3.8) but had severe OSAS (mean RDI, 55.1 ± 35.1). When controlled for age, RDI, and LSAT, the white men were substantially more obese (mean BMI, 29.7 ± 5.8, P = .0055). When controlled for age and BMI, the white men had less severe illness (RDI, 34.1 ± 17.9, P = .0001). Although the posterior airway space and the distance from the mandibular plane to hyoid bone were less abnormal in the Far‐East Asian men, the cranial base dimensions were significantly decreased. Conclusions The majority of the Far‐East Asian men in this study were found to be nonobese, despite the presence of severe OSAS. When compared with white men, Far‐East Asian men were less obese but had greater severity of OSAS. There may be differences in obesity and craniofacial anatomy as risk factors in these two groups.     

A new modification of uvulopalatopharyngoplasty for the treatment of obstructive sleep apnea syndrome

Objective

To evaluate objective and subjective improvement after applying a new surgical technique, two-piece palatopharyngoplasty (Two-P4), to the treatment of obstructive sleep apnea syndrome (OSAS).

Methods

Twenty-four patients with mild to severe OSAS underwent Two-P4 between January 2002 and November 2007. Polysomnography and Epworth Sleepiness Scale (ESS) score were used to evaluate surgical results.

Results

Mean apnea–hypopnea index (AHI) improved from 50.9 to 10.7 after Two-P4. Mean ESS score decreased significantly from 13.0 to 7.7. Body mass index was unchanged after surgery. Objective success as evaluated by a 50% reduction in AHI and by AHI <20 was obtained in 22 of 24 patients (91.7%). Mean reduction in AHI was 76.9% for all 24 patients, 86.2% for patients with Friedman's anatomical stage I, 78.9% for stage II, and 54.5% for stage III.

Conclusion

Two-P4 is a novel surgical treatment for OSAS patients with a high success rate (91.7%) as evaluated by reductions in AHI. Two-P4 keeps the middle soft palate intact to form independent scars on both sides, which constrict to stretch the soft palate and widen the pharyngeal space.

Dissociation between objectively quantified snoring and sleep quality

BackgroundThe impact of simple snoring on sleep structure and sleepiness has not been well described. In several studies, self-reported snoring was associated with increased daytime sleepiness. However, most studies did not distinguish patients with simple snoring from those with coexisting obstructive sleep apnea (OSA) using objective measures. We therefore evaluated the relationship between objectively measured snoring and both sleep structure and daytime sleepiness in patients with no or mild OSA.MethodsSubjects referred for suspected sleep disorders underwent polysomnography (PSG) during which breath sounds were recorded by a microphone. Those with an apnea-hypopnea index (AHI) <15/h were analyzed. Individual snores were identified by a computer algorithm, from which the snore index (SI) was calculated as the number of snores/h of sleep. Sleep stages and arousals were quantified. Daytime sleepiness was evaluated using the Epworth Sleepiness Scale (ESS) score.Results74 (35 males) subjects were included (age, mean ± SD: 46.4 ± 15.3 years and body mass index: 29.8 ± 7.0 kg/m²). The mean SI was 266 ± 243 snores/h. Subjects were categorized according to their SI into 3 tertiles: SI < 100, between 100–350, and >350. No sleep structure indeces, arousals, or ESS score differed among SI tertiles (p > 0.13). There was no correlation between SI and any of these variables (p > 0.29). In contrast, the AHI was significantly related to frequency of arousals (r = 0.23, p = 0.048).ConclusionsThese findings suggest that simple snoring assessed objectively is not related to indices of sleep structure or subjective sleepiness.
