Filter by:SureCRIC is intended to be used as an accessory to cricothyrotomy and tracheotomy devices, helping to identify and stabilize anatomical landmarks for establishing an airway. Cricothyroid membrane identification accuracy has been reported to be 30-62% in the literature [Bai15, Ell10, Kri15, Lam15]. The current study assesses SureCRIC-assisted medic performance in identifying the cricothyroid membrane in a diverse standardized patient population.
The purpose of this study is to evaluate the association of signals recorded and analysed with Ventica® LFTS in infants and preschoolers during acute airway obstruction/asthma exacerbation and recovery thereof for changes in the IP-derived TBFV curves within and between nights.
The inclined position at 30 ° in case of transient respiratory discomfort is recommended since the consensus conference of September 2000. This recommendation is based on a low level of evidence (grade C). This advice is found in the health book, and in many tips for parents. However, it does not comply with the recommendations of the American Academy of Pediatrics for sleeping on the back, on a firm mattress and without other objects in the bed. 70% of pediatricians advise this position in a specific medical context according to a study of Bellaïche conducted in 2013. 40% of parents use it for no particular reason. Anatomically, the upper airways of infants are of reduced caliber, and therefore at risk of obstruction. A study by Bergougnioux on the cases of MIN in infants wearing a wrap-around sling shows that the flexion of the neck causes the chin to be positioned against the chest and contributes to the suffocation of the infant. This is especially important in infants under 3 months whose neck muscles do not yet support the weight of the head. The 2009 InVS national survey of unexpected infant deaths shows that bed crashes accounted for 11.1% of all deaths reported. Among unexplained deaths, maladaptive bedding was a contributing factor, including the use of a pillow in the bed in 24.3% of cases. It was observed in the study by Kornhauser Cerar et al in 2009 that half-sitting in a car seat for an extended duration was at the origin of a significant desaturations rate, which was also found in the car bed group. The control group "hospital bed" was not subject to these desaturations. These results support the fact that only an adapted bedding that complies with the recommendations protects against asphyxiation. Since 2016, INPES recommends in its advice sheet on bronchiolitis for parents, a flat bed on the back. Hypothesis : The inclined position in infants under one year of age is at risk of unexpected death of the infant by obstruction of the upper airways, because of the changes of position that it entails, including a risk of slipping at the bottom of the bed and of asphyxiation under the covers.
The purpose of this study is to establish the reference values of impulse oscillometry (IOS) in healthy Chinese, and compare the indices of IOS in patients with lung disease, such as chronic obstructive pulmonary disease (COPD), asthma, interstitial lung disease (ILD), and upper airway Obstruction (UAO).
The investigators propose a preliminary study performing exome sequencing on samples from patients and their biologically related family members with tracheal and esophageal birth defects (TED). The purpose of this study is to determine if patients diagnosed with TED and similar disorders carry distinct mutations that lead to predisposition. The investigators will use advanced, non-invasive magnetic resonance imaging (MRI) techniques to assess tracheal esophageal, lung, and cardiac morphology and function in Neonatal Intensive Care Unit (NICU) patients. MRI techniques is done exclusively if patient is clinically treated at primary study location and if patient has not yet had their initial esophageal repair.
This study was designed as retrospective chart review to test our hypothesis whether there are the differences in inflammatory and anti-inflammatory mediators between asthmatic and ACOS patients with small airway obstruction, and COPD
Introduction: Endotracheal intubation and mechanical ventilation are lifesaving interventions that are commonly done in the intensive care unit (ICU). The act of intubating someone can cause laryngeal edema (LE) that, if extensive enough, can cause airway obstruction after a patient is extubated. To date, the only test that is available to predict this complication is the cuff leak test (CLT). However, its diagnostic accuracy is uncertain as there have been no randomized controlled trials (RCT) examining this. The Cuff leak and airway Obstruction in Mechanically ventilated ICU patients (COMIC) Randomized Control Trial will be done to examine the impact of CLT on postextubation stridor and reintubation. Subsequently, describing the diagnostic accuracy of this test. Methods: This will be a multi-center centered, pragmatic, double blinded RCT. Mechanically ventilated patients in the ICU, who are deemed ready to be extubated will be included. All patients will have a CLT done prior to extubation. The results of the CLT in the intervention arm will be communicated to the treating physician, and decision to extubate will be left to the treating team, while the results of the CLT for patients in the control arm will not be communicated to the treating physician, and the patient will be extubated, regardless of the result of the CLT. Objective: This is a pilot trial to assess feasibility of conducting a powered RCT. Feasibility outcomes include: consent rate, recruitment rate, and protocol adherence. Clinical outcomes will include postextubation stridor, reintubation, emergency surgical airway, ICU mortality, in hospital mortality, duration of mechanical ventilation, and ICU length of stay in days.
This clinical trial is a monocentric, prospective, observational and controlled trial (historical cohort control group of healthy non-obese subjects who had Nasal functional exploration for Snoring) as part of current care. This study concerns the prevalence of obstructive sleep apnea syndrome (OSAS). OSAS is elevated in subjects with morbid obesity (BMI≥40) (on average 70%). International recommendations agree on the need to seek OSAS before bariatric surgery because of the high risk of complications. Increased nasal resistance could also be related to a limitation of inspiratory flow due to an abnormality of the elasticity of the nasal mucosa or "nasal compliance". Adipose infiltration of the nasal mucosa may occur during obesity. These tissue changes (decreased vaso-erectile tissue and increased adipose tissue) could modify the nasal compliance, which the decrease would be a possible factor of severity of OSAS in obese patients. Screening for an abnormality of compliance could also anticipate a difficulty of equipment for Continuous Positive Airway Pressure (CPAP) in the case of associated OSAS. All patients who must have bariatric surgery and get in the criteria are included. They will have to do a medical checkup pre and post-operative (polygraphy + ear/nose/throat assessment (ENT) + Nasal functional exploration). They will be followed for 13 to 24 months. The main objective of this research is to demonstrate a reduction of at least 30% of nasal compliance in a group of obese subjects (BMI> 35) compared to a control group of healthy subjects. The secondary objectives are to is to demonstrate an increase of 30% in resistance in patients with BMI> 35 compared to control group and a normalization of nasal compliance 1 year after surgery when their weight is normalized (BMI <30). A study period of 4 years is planned.
The goal of this clinical research study is learn about side effects and the success of bronchoscopies when performed in cancer patients with and without symptoms. This is an investigational study. Up to 110 patients will take part in this study. All will be enrolled at MD Anderson.
