Patient factors associated with difficult flexible bronchoscopic intubation under general anesthesia: a prospective observational study.

Patient factors associated with difficult flexible bronchoscopic intubation under general anesthesia: a prospective observational study. Can J Anaesth. 2020 Jan 17;: Authors: Touré T, Williams SR, Kerouch M, Ruel M Abstract PURPOSE: Patient characteristics associated with difficult tracheal intubation using a flexible bronchoscope (FB) under general anesthesia have not been prospectively evaluated. This observational study aimed to identify demographic and morphologic factors associated with difficult FB intubation. METHODS: We recruited 420 adult elective surgery patients undergoing tracheal intubation during general anesthesia. Patients characteristics were recorded including age, sex, weight, height, body mass index, American Society of Anesthesiologists physical status, history of snoring, obstructive sleep apnea, Mallampati score, upper lip bite test score, neck circumference and skinfold thickness, maximal neck flexion and extension angles, absence of teeth, Cormack and Lehane grade, presence of blood or secretions during intubation, as well as the inter-incisor, thyromental, sternothyroid, and manubriomental distances. The time (duration) needed to complete intubation (primary endpoint) and the number of attempts needed were correlated with these patient characteristics in a multivariable analysis. RESULTS: Intubation was successful on the first attempt in 409/420 patients (97%). Seven patients (1.7%) needed more than one attempt....

Authors: Dzięciołowska-Baran E, Gawlikowska-Sroka A, Szczurowski J Abstract Polysomnography, a gold standard for the diagnosis of sleep-disordered breathing, is a complex investigation requiring access to the sleep laboratory. Thus, sleep-disordered breathing could be underdiagnosed. The aim of this paper was to investigate the feasibility and effectiveness of self-performed investigation of obstructive sleep apnea (OSA) in the home setting, using a portable device, and to assess the comfort and simplicity of the procedure from the patient's perspective. The study included 68 middle-aged patients (21 women and 47...

C, Alonso-Fernández A, Barceló A Abstract BACKGROUND AND OBJECTIVES: Available evidence suggests a familial basis for OSA. The aim of the present study was to assess the potential influences of parental OSA in predicting the diagnosis and severity of OSA in snoring children. METHODS: Observational study, we prospectively enrolled 84 children and their parents. A complete nocturnal polysomnography was performed. Children were categorized into 3 severity groups according to the apnea-hypopnea index (AHI

n O Abstract Signs of both motor and sensory nervous lesions have previously been shown in the upper airway of obstructive sleep apnea (OSA) patients and habitual snorers. HYPOTHESIS: snoring per se may damage all upper airway neurons over time, thereby causing progression to manifest sleep apnea. To test this, non-snoring subjects, untreated snorers and CPAP-treated patients underwent repeated sensory testing in the soft palate in a prospective long-term study. METHODS: Cold detection threshold (CDT) testing at soft palate and lip with a thermode and nocturnal respiratory recordings were performed in 20...

Abstract Clinical factors associated with daytime sleepiness and insomnia in persons with epilepsy (PWE) were examined in this cross-sectional study of 126 participants (men, 50.8%). Excessive daytime sleepiness (EDS; score of ≥11 on the Epworth Sleepiness Scale (ESS)) was noted in 17.5% of participants (mean score, 6.1 ± 4.2), and moderate-to-severe insomnia (Insomnia Severity Index (ISI) scores of ≥15) was noted in 20.6% (mean score, 7.8 ± 6.4). Linear regression analyses revealed that ESS scores were independently associated with obstructive sleep apnea (OSA; snoring, tiredness, obse...

AbstractObjective/hypothesisTo investigate the impact of obstructive sleep apnea syndrome (OSAS) on the olfactory and gustatory functions, and the potential mechanisms affecting olfactory and gustatory functions.Materials and methodsA total of 120 men between the ages of 41 and 70 (mean age (SD) = 56 ± 7.5) were divided into three groups according to polysomnography results: snoring group, mild to moderate OSAS group, and severe OSAS group. Olfactory and gustatory functions were evaluated by the Sniffin’ Sticks test and the triple-drop method, respectively. Otorhinolaryngologic examination, a s well as sleep a...

CONCLUSIONS: Patients with 22q11.2DS are medically complex and are at increased risk of OSA at baseline. Wide PPF surgery for severe VPD does not significantly increase risk of OSA. Careful perioperative planning is essential to optimize both speech and sleep outcomes. PMID: 31973553 [PubMed - as supplied by publisher]

This study shows reducing excess fat in general can reduce tongue size,” said Dr. Raj Dasgupta, a sleep specialist at Keck Medicine at the University of Southern California, who was not involved in the study. In the new paper, the researchers used MRI imaging to measure the effect on upper airways of a 10% weight loss in 67 obese patients. The images showed reducing tongue fat was the primary reason overall sleep apnea scores improved by 31%. “In fact, the more tongue fat you lost, the more your apnea improved,” said Schwab, who is the co-director of the Penn Sleep Center at Penn Medicine. Costs of sleep ...
