Filter by:The goal of this prospective observational study is to test combination of STOP-Bang score and factors predicting difficult intubation can improve accuracy of prediction difficult mask ventilation in obese patients that undergoing to elective surgery under general anesthesia. The main question[s] it aims to answer are: - Can combination of STOP-Bang score and factors predicting difficult intubation improve accuracy of prediction difficult mask ventilation in obese patients? - Study about complication after endotracheal tube insertion in obese patients that undergoing to elective surgery under general anesthesia. Participants who undergoing to elective surgery under general anesthesia will - Routine preoperative evaluation and ask about STOP bang questions, evaluate neck circumference, Mallampati grade,Thyromental distance (That routine physical examination for anesthetic care pre-operation) - In operation room, patients will be inducted anesthesia by anesthesiologist (step routine for general anesthesia),observe difficult mask ventilation grading before intubate endotracheal tube and complication after endotracheal tube insertion. If there is a comparison group: Researchers will compare obese patients with/without high STOP bang score >=3 point plus factor predicting difficult intubation (Mallampati grade 3-4, Neck circumference > 42 cm, Thyromental distance < 6 cm)to prediction difficult mask ventilation
This prospective, controlled study will compare the 3D cephalometric analysis of bone and craniofacial soft tissues in young (18-35 years) non-overweight apneic adults phenotype between a test group (with AHI 15) and a control group (healthy subjects with AHI < 15).
Early feasibility study to estimate the functionality of a novel intervention based on non-invasive transcutaneous electrical stimulation of the hypoglossal nerve to reduce the Apnea Hypopnea Index (AHI).
To evaluate efficacy of CPAP Therapy on Pulmonary Function Test in Patients With COPD-OSA Overlap Syndrome
The VicTor Study is a randomized, double blind, placebo-controlled, 3-period, multiple-dose crossover study in participants with OSA.
The goal of this descriptive, cross-sectional survey design is to determine the effect of public awareness video on the basic knowledge regarding sleep apnea syndrome or glaucoma and traffic accidents in normal population The main questions it aims to answer are: - To assess the attitudes toward the health-related cause of traffic accidents, mainly focused on obstructive sleep apnea and glaucoma among Thai people who viewed the local language translated versions of the public awareness video. - To assess the feedbacks of the public awareness video. Participants will be ask to complete a set of questionnaires containing 3 parts - pre-test part - educational video part - post-test part
Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea(OSA) are common disorders ,the co-existence of both conditions is called overlap syndrome Smoking , obesity , airway resistance and inflammation are considered risk factors for both conditions ,interestingly either COPD and OSA are associated with increased cardiovascular complications with further increased risk in overlap syndrome Multiple theories could explain that one disorder can predispose or exaggerate the other. For example, in COPD cigarette smoking and inhaled steroids are linked to myopathy of upper airway dilator muscles. Moreover in core-pulmonale redistribution of edema fluid in supine position during sleep can also contribute to or exacerbate OSA . On the other hand , OSA patients might smoke frequently and more heavily to compensate for excessive daytime sleepiness and to help them to lose weight , which results in exaggerated airway inflammation and exacerbate COPD. Rationale of the study was to assess the prevalence and predictors of OSA among patients with stable COPD.
This study intends to investigate the improvement in patients with OSA through objective measurement, including oxygen desaturation index (ODI) and the percentage reduction in intermittent mouth puffing (IMP) before and after the intervention. The oral appliances are placed between the tongue and the soft palate to reduce the oral ventilation space. A total of 24 participants aged between 36 and 57 years were identified with ODI above 5 events/hour by measuring their blood oxygen and with an originally designed mouth puffing detector to find out those who were still mouth-puffed when their mouths were taped. A suitable appliance was chosen for the participants between the two originally designed oral appliances, tongue pressed device (TPD) and tongue elevated device (TED), and the intervention lasted for six weeks.
High flow, humidified, temperature-regulated nasal insufflation is not a new concept. It is used widely in the treatment of hypoxaemic respiratory failure in critically ill patients, as an alternative to non-invasive positive ventilation via face or nasal mask. Recently, its use has been extended to the perioperative setting for pre-oxygenation and prolonging apnoeic time to desaturation. Both CPAP and high flow nasal cannula insufflation devices are licensed for use clinically in Singapore. We conduct this pilot study because its perioperative use in our adult OSA population is currently not well-defined.
The aim of the present project is to analyze the impact from orthognathic surgery on the upper airway respiratory volume. The primary objective is comparison of differences in the in the airway changes due to maxillary movements and mandibular movements. Secondary objectives are the analysis of any correlation between the magnitude of the movement and the airway volume, correlation between the direction of the movements and the changes in airway volume and correlation with Health-Related Quality of Life (HRQoL). Expected confounding factors like smoking habits and Body Mass Index (BMI) will be analyzed.
