Obstructive Sleep Disordered Breathing

Radiofrequency proves to be a useful tool for snoring and obstructive sleep apnoea cases. Its advantages include relative precision in incision making, relatively bloodless fields if used appropriately, decrease postoperative pain and excellent healing with fibrosis which aids in stiffening tissues. Radiofrequency is high frequency alternating current used to ablate (cut/coagulate) tissues. Radiofrequency ablation treatment can be applied to nasal turbinates, soft palate, tongue base, tonsils etc and it can be used in various surgeries in the cutting mode to improve obstructive sleep disordered breathing.

AbstractObjective:To assess the quality of life of UK children with sleep-disordered breathing undergoing adenotonsillectomy, by using the Obstructive Sleep Apnoea 18 questionnaire and determining score changes and effect sizes.Design:Prospective, longitudinal study.Setting:The otolaryngology department of a university teaching hospital in Northern England.Participants:Twenty-eight children for whom adenotonsillectomy was planned as treatment for sleep-disordered breathing, and who had either a clinical history consistent with obstructive sleep apnoea or a polysomnographic diagnosis.Main outcome measure:The Obstructive Sleep Apnoea 18 questionnaire, a previously validated, disease-specific quality of life assessment tool; changes in questionnaire scores and effect sizes were assessed.Methods:The Obstructive Sleep Apnoea 18 questionnaire was administered to each child's parent pre-operatively, then again at the follow-up appointment. Questionnaire scores ranged from 1 to 7. Score changes were analysed using the paired t-test; effect sizes were calculated using 95 per cent confidence intervals.Results:Complete data were obtained for 22 children (mean age, 61 months). Ten had undergone pre-operative polysomnography. Twenty-one children underwent adenotonsillectomy (one underwent tonsillectomy). Median follow up was eight weeks (interquartile range, six to 11 weeks). Following surgery, the overall mean score improvement was 2.6 (p < 0.0001) and the mean effect size 2.4 (95 per cent confidence interval 1.9 to 2.8). There were significant improvements in each of the individual questionnaire domains, i.e. sleep disturbance (mean score change 3.9, p < 0.0001), physical suffering (2.2, p < 0.0001), emotional distress (2.0, p = 0.0001), daytime problems (1.8, p = 0.0001) and caregiver concerns (2.6, p < 0.0001).Conclusion:In these children with sleep-disordered breathing treated by adenotonsillectomy, Obstructive Sleep Apnoea 18 questionnaire results indicated significantly improved mean score changes and effect sizes across all questionnaire domains, comparing pre- and post-operative data.

Sleep disordered breathing 254 Sleep disordered breathing is a relatively new area of respiratory medicine. It encompasses two broad and sometimes overlapping groups: the first and largest is obstructive sleep apnoea (OSA), and the second is the nocturnal hypoventilatory disorders. Both require nocturnal respiratory support, usually via a nasal or face mask, although sometimes via a tracheostomy. The on-call acute physician will be consulted about patients who have sleep disordered breathing and hence should be aware of the diagnoses and the therapies....

Obesity hypoventilation syndrome (OHS) is defined as a combination of obesity (body mass index ≥30 kg·m−2), daytime hypercapnia (arterial carbon dioxide tension ≥45 mmHg) and sleep disordered breathing, after ruling out other disorders that may cause alveolar hypoventilation. OHS prevalence has been estimated to be ∼0.4% of the adult population. OHS is typically diagnosed during an episode of acute-on-chronic hypercapnic respiratory failure or when symptoms lead to pulmonary or sleep consultation in stable conditions. The diagnosis is firmly established after arterial blood gases and a sleep study. The presence of daytime hypercapnia is explained by several co-existing mechanisms such as obesity-related changes in the respiratory system, alterations in respiratory drive and breathing abnormalities during sleep. The most frequent comorbidities are metabolic and cardiovascular, mainly heart failure, coronary disease and pulmonary hypertension. Both continuous positive airway pressure (CPAP) and noninvasive ventilation (NIV) improve clinical symptoms, quality of life, gas exchange, and sleep disordered breathing. CPAP is considered the first-line treatment modality for OHS phenotype with concomitant severe obstructive sleep apnoea, whereas NIV is preferred in the minority of OHS patients with hypoventilation during sleep with no or milder forms of obstructive sleep apnoea (approximately <30% of OHS patients). Acute-on-chronic hypercapnic respiratory failure is habitually treated with NIV. Appropriate management of comorbidities including medications and rehabilitation programmes are key issues for improving prognosis.

IntroductionObstructive sleep apnoea (OSA) is a common sleep disorder with a high social and economic burden. Thus, early prediction and diagnosis of OSA are important. Changes in metabolism and the microbiome may serve as biomarkers for OSA. Herein, we review the literature on the metabolomic and microbiome changes associated with OSA, and identify the metabolites and microorganisms involved.MethodsWe searched the PUBMED and EMBASE electronic databases using the following terms: “obstructive sleep apnea”, “OSA”, “sleep disordered breathing”, “SDB”, “intermittent hypoxia”, “sleep fragmentation”, and either “metabolomics” or “microbiome”. In total, 273 papers were identified, of which 28 were included in our study.ResultsChanges in the levels of certain metabolites related to fatty acid, carbohydrate and amino acid metabolism were associated with the incidence of OSA. The diversity and abundance of microflora, particularly Firmicutes and Bacteroidetes, were altered in humans and rodents with OSA.ConclusionsCertain changes in metabolism and the microbiota play an integral role in the pathophysiology of OSA and OSA-induced cardiovascular complications. Metabolomic and microbiome biomarkers shed light on the pathogenesis of OSA, and facilitate early diagnosis and treatment.

RationaleSleep-disordered breathing (SDB) is highly prevalent after stroke. The clinical and ventilatory chemosensitivity characteristics of SDB, namely obstructive, central and coexisting obstructive and central sleep apnoea (coexisting sleep apnoea) following stroke are poorly described.ObjectiveTo determine the respective clinical and ventilatory chemosensitivity characteristics of SDB at least 3 months after a first ischaemic stroke.MethodsCross-sectional analysis of a prospective, monocentric cohort conducted in a university hospital. 380 consecutive stroke or transient ischaemic attack patients were screened between December 2016 and December 2019.Measurements and main resultsFull-night polysomnography, and hypercapnic ventilatory response were performed at a median (Q1; Q3) time from stroke onset of 134.5 (97.0; 227.3) days. 185 first-time stroke patients were included in the analysis. 94 (50.8%) patients presented no or mild SDB (Apnoea-Hypopnoea Index <15 events/hour of sleep) and 91 (49.2%) moderate to severe SDB, of which 52 (57.1%) presented obstructive sleep apnoea and 39 (42.9%) coexisting or central sleep apnoea. Obstructive sleep apnoea patients significantly differed regarding their clinical presentation from patients with no or mild SDB, whereas there was no difference with coexisting and central sleep apnoea patients. The latter presented a higher frequency of cerebellar lesions along with a heightened hypercapnic ventilatory response compared with no or mild SDB patients.ConclusionSDB in first-time stroke patients differ in their presentation by their respective clinical traits and ventilatory chemosensitivity characteristics. The heightened hypercapnic ventilatory response in coexisting and central sleep apnoea stroke patients may orientate them to specific ventilatory support.
