“…In particular, the "Observed" item showed a very high odds ratio of 6.0, compared with those of the other two items, which were nearly 1.4. Although it usually refers to observation by non-medical personnel, this result is consistent with the intuition that the "Observed' item is highly correlated with OSA, and similar reports have been made in studies such as Neves Junior et al [18].…”

Background: The STOP-BANG questionnaire is a simple screening tool with high sensitivity for the detection of severe obstructive sleep apnea (OSA). Predicting airway obstruction would allow the safe management of sedative patients to prevent intraoperative hypoxia. This study was designed to check the correlation between the STOP-BANG score and oxygen saturation (SpO2) during sedation and confirm the availability of the STOP-BANG questionnaire as a preoperative exam for predicting the incidence of hypoxia in sedative patient management.Methods: This study included 56 patients who received spinal anesthesia. The pre-anesthesia evaluation was conducted using the STOP-Bang questionnaire. The patients were under spinal anesthesia with an average block level of T10. Dexmedetomidine was infused with a loading dose of 1 μg/kg over 10 min and a maintenance dose of 0.5 μg/kg/h until the end of the procedure. The SpO2 of the patients was recorded every 5 min.Results: The STOP-Bang score was negatively correlated with the lowest SpO2 (coefficient = –0.774, 95% confidence interval [CI]: –0.855 to –0.649, standard error [SE] = 0.054, P < 0.001). The item of “observed apnea” was the most correlated one with hypoxic events (odds ratio = 6.00, 95% CI: 1.086 to 33.145).Conclusions: The STOP-BANG score was significantly correlated with the lowest SpO2 during spinal anesthesia, which enabled the prediction of meaningful hypoxia before it occurred in the sedated patients.

“…However, the sensitivity and specificity of the screening model are usually inversely correlated, and high sensitivity is often gained at the expense of specificity. 7,11 For diseases such as OSA combined with hypertension, it may be more important that the screening test has high sensitivity so as not to miss OSA patients rather than having high specificity. 17 The Berlin questionnaire classifies patients as high-risk or low-risk based on self-reports of snoring, daytime sleepiness, hypertension and obesity, with different sensitivity and specificity in different studies.…”

“…It was initially used to screen surgical patients, but later proved to be a high-quality method with good consistency in identifying the severity of OSA in patients. 9,11 The Berlin questionnaire was developed by a group of respiratory and primary care doctors in Germany in 1996 through consensus, and has become a qualitative diagnostic tool for OSA that is widely used in the world. 12 In the design of some of these scales, hypertension is considered a risk factor for OSA.…”

Background: Obstructive sleep apnea (OSA) is often accompanied by other complications, especially hypertension. Hypothesis: The purpose of this study is to compare the application value of six tools in the screening of OSA in patients with hypertension. Compared with other questionnaires, we hypothesized that Berlin performed better in screening hypertensive patients suspected of OSA. Methods: In this study, we collected the basic data and polysomnography (PSG) data of patients diagnosed with hypertension who underwent PSG at the Sleep Medicine Center of the First Affiliated Hospital of Guangzhou Medical University from April 2012 to March 2021. The sensitivity, specificity, positive predictive value, negative predictive value, area under the curv (AUC) and diagnostic odds ratio (DOR) of the six screening tools were then calculated, and their correlation with the sleep apnea hypopnea index (AHI) analyzed.Results: There were 303 males (303/398, 76.1%) out of 398 hypertension patients suspected of OSA. The area under the curve of the Berlin questionnaire's receiver operating characteristic (ROC) curve reached 0.753 (95%CI: 0.707-0.794). When the AHI was 5, 15 and 30 times/h as the cut-off points, the sensitivity and negative predictive value of Berlin were the highest at 0.947 and 0.630, 0.970 and 0.851, and 0.988 and 0.957 respectively, while the specificity and positive predictive value of the Epworth Sleepiness Scale (ESS) were the highest at 0.

“…While a STOP-BANG score of 5–8 identifies patients with a high probability of moderate or severe OSAS [ 43 ]. A score of 3 or higher has been confirmed to offer a high sensitivity to identify sleep apnea and seems to be a suitable cutoff value for screening purpose [ 19 , 44 ], as even with a mild status of OSAS oxygen desaturation occurs during sleep [ 45 ]. Furthermore, we supposed that the patients in our moderate to high risk group were at least suspected of being affected to intermittent hypoxemic episodes while sleep.…”

Short term cognitive function after sevoflurane anesthesia in patients suspect to obstructive sleep apnea syndrome: an observational study

et al. 2021

Background The obstructive sleep apnea syndrome (OSAS) is characterized by intermittent cerebral hypoxia which can cause cognitive alterations. Likewise, hypoxia induced neurocognitive deficits are detectable after general anesthesia using volatile anesthetics. The objective of this study was to evaluate the association between a moderate to high risk patients of OSAS and postoperative cognitive dysfunction after volatile anesthesia. Methods In this single center prospective, observational study between May 2013 and September 2013, 46 patients aged 55 to 80 years with an estimated hospital stay of at least 3 days undergoing surgery were enrolled. Patients were screened using the STOP-BANG test with score of 3 or higher indicating moderate to high risk of OSAS. The cognitive function was assessed using a neuropsychological assessment battery, including the DemTect test for cognitive impairment among other tests e.g. SKT memory, the day before surgery and within 2 days after extubation. Results Twenty-three of the 46 analyzed patients were identified with a moderate to high risk of OSAS. When comparing post- to preoperative phase a significant better performance for the SKT was found for both groups (p < 0.001). While the moderate to high risk group scores increased postoperative in the DemTect test, they decreased in the low risk group (p < 0.003). When comparing the changes between groups, the moderate to high risk patients showed significant better test result for DemTect testing after anaesthesia. This effect remained robust when adjusting for potential confounding variables using a two-factor ANOVA. Conclusion Compared to low risk, a moderate to high risk of OSAS based on the STOP-BANG score was associated with improved postoperative cognitive function measured by the DemTect test. Trial registration The study was approved by the local Ethics committee (Ethikkommission der Medizinischen Fakultät der Friedrich-Alexander-Universität Erlangen-Nürnberg, Erlangen, Germany) (reference number: 87_12 B) on 19.04.2012.
