Filter by:The aim of this study was to investigate the airway inflammatory profile and the clinical presentation of chronic obstructive pulmonary disease (COPD) in never smokers compared to smokers with COPD.
this study aim to compare the effect of early rehabilitation program on mechanical ventilated COPD patient in Respiratory ICU to those using current standard care as regarding : - morbidity and thirty day mortality - diaphragm function and weaning outcomes. - disease exacerbation - Duration spent on ventilator. - Length of ICU stay
This study will assess whether the type of simulation model used in cricothyroidotomy training has an effect on the subsequent confidence and competence in the procedure.
Currently, there are no tools that can measure nasal airflow in an objective manner that is non-invasive to the patient. This clinical study aims to address this by evaluating the use of thermal imaging as a diagnostic tool for measuring nasal airflow. Proper airflow cools the nasal airway as it passes--obstructions or narrowed airways hinder flow and results in elevated temperatures along the airway and nasal tissue. It is this elevation in temperature, or more specifically, loss of cooling, that we hypothesize to be measurable with thermal imaging. Participants in this study will be asked to perform 3-4 nasal breathing cycles which will be recorded by the thermal imager.
The aim of such study is to compare three different school-based (in nurseries, kindergartens and primary schools) interventions aimed at teaching to families how to prevent food choking injuries. The topic of food choking primary and secondary prevention is placed in a more general topic regarding food safety, including education on food labeling and on food waste prevention.
Assessment of the airway forms part of routine anesthetic practice. However, the predictions referred to intubation or ventilation difficulties are usually inconclusive. In effect, the failure rate in predicting such difficulties exceeds 60%. In this scenario it is not possible to know whether a given patient will be difficult to intubate and ventilate. These are referred to as non-intubate and non-ventilate cases with a high risk of severe neurological complications and even death due to hypoxemia. According to all the clinical guides, the solution in such cases usually involves the use of supraglottic devices that rescue oxygenation through effective ventilation. In the event of ventilation failure with a supraglottic device, it is currently not possible to know whether the device is correctly positioned, unless some other instrument such as a flexible fiberscope is used to visualize the anatomy beyond the ventilation device. The TotalTrack is a new device with all the characteristics of a supraglottic device that moreover includes a camera at the tip, allowing us to confirm anatomical positioning with respect to the glottic structures. This device also allows intubation under indirect visualization of the glottis, thus adding the possibility of definitive patient lung isolation. The primary objective of this study is to determine the capacity to visualize the glottic structures through the camera of the TotalTrack device, compared with glottic visualization afforded by indirect laryngoscopy in the same patient. The Cormack-Lehane scale and percentage of glottic opening (POGO) are used for this purpose. The secondary objectives comprise assessment of the ventilation, intubation and TotalTrack device withdrawal times. The hemodynamic changes associated to both techniques during intubation and TotalTrack device withdrawal are also evaluated. Minimum patient oxygenation throughout the procedure is assessed. The sealing and ventilation pressures during operation of the TotalTrack device are recorded. Likewise, an analysis is made of the number of placement attempts, visualization improvement maneuvers, and minor complications associated to the use of the TotalTrack device (presence of blood upon withdrawal or pharyngeal pain), with their degree of severity.
It has been observed that COPD exacerbations are under-reported in China. One of the reasons for this is Chinese subjects with COPD cannot describe the symptoms of exacerbation mentioned in English. Hence this study aims to create a tool called CERT that will help Chinese physicians and subjects with COPD to recognize and report exacerbations. The study will be carried out in 4 stages: item identification, cognitive briefing, item reduction and creation of final CERTs. Two CERTs will be prepared, one for subjects with COPD and another for physicians. A total of approximately 200 subjects will be included in the study and each subject will contribute to only one step.
Failed intubation is currently one of the most important factors leading to morbidity and mortality in anesthesia. The development of supraglottic airway devices (SGDs), such as the intubating laryngeal tube, has revolutionized airway management, as these devices allow adequate ventilation and oxygenation in situations where ventilation and/or intubation via conventional means pose a challenge. Several publications describe the usefulness of such devices for salvaging ventilation in patients that cannot be intubated with direct laryngoscopy or who cannot be ventilated with a facemask. In these salvage situations, SGDs are highly effective in achieving adequate patient oxygenation. Achieving effective oxygenation with an SGD and completely isolating the airway by intubation at the same time. This is now possible thanks to the so called supraglottic intubation devices (SGIDs). For that reason, we believe it is necessary to conduct a study that allows evaluation of the performance of this device in the context of daily clinical practice. Its design characteristics, its capacity to be used in intubation applications, its soft and atraumatic materials as well as its disposability augur this product a significant expansion in the next few years. Nonetheless, no data are available on the success of intubation when the intubating laryngeal tube suction device (ILTSD) is used. The idea behind this study is to assess the possibilities to use the ITLSD device to intubate patients in regular anesthetic practice.
This study evaluates subjective and objective measures of treatment outcome after using the Aerin Medical Vivaer™ Stylus to treat nasal obstruction
The Articulating Oral Airway (AOA) is a novel oral airway which actively displaces the tongue, allowing for a greater cross-sectional area for mask ventilation. The investigators hypothesize that, in patients with predictors for difficult mask ventilation, the AOA will be non-inferior to the Geudel oral airway in terms of expired tidal volumes.
