Active clinical trials for "Airway Obstruction"

In a prospective, observational study the investigators compared resistance values measured using the airway perturbation device (APD) to impulse oscillometry and spirometry. The investigators also created reference equations for normal APD resistance ranges using the data from clinically normal volunteers.

Pre-Hospital Advanced Airway Management (PHAAM) is a potentially lifesaving intervention. A recent Danish multicentre single country study demonstrated a 99,7% incidence of successful anaesthesiologist pre-hospital endotracheal intubation, with a PHAAM-related complication rate of 7.9%. A London study revealed a significantly higher intubation failure rate among non-anaesthesiologist physicians. In Scandinavia different types of emergency medical services (EMS) and professions provide PHAAM. The success rate of prehospital endotracheal intubation (PHETI), incidence of difficult intubation and complications in the Nordic countries is not known. The aim of this study is to define PHAAM success rate and complications in different types of Nordic EMS organisations and physician critical care teams. The study is a prospective observational study with collection of PHAAM data according to the template by Sollid et al. in the 12 participating Nordic Countries EMS/HEMS centres and physician critical care teams. The primary endpoint is PHETI success on ≤2 attempts and no complications.

After a structured teaching program anaesthetists are educated in identifying the cricothyroid membrane with ultrasonography. Thereafter their ability to do so is compared with their ability to do so with palpation. In an obese volunteer

This study is a non-randomized, observational, non-comparative prospective study to evaluate the safety, efficacy and performance of the LMA Supreme laryngeal mask airway when used according to the device's Instructions for Use.

Background: Foreign body airway obstruction (FBAO) is often described as an uncommon cause of Out of Hospital Cardiac Arrest (OHCA) accounting for approximately 1.4% of all OHCA. Reported incidents rates of FBAO causing cardiac arrest are unclear, and first aid by layperson are not well described. The aim of the epidemiological part of the study is: to investigate information on actions taken by EMS-personnel and laypersons to investigate outcomes of hypoxic Cardiac Arrest due to foreign body airway obstruction in Denmark to increase overall survival. propose new guidelines and strategies to increase survival from OHCA caused by FBAO. The aim of advanced text-string search algorithm part of the study is - To investigate if an advanced text-string search algorithm can identify FBAO in medical records with high sensitivity Methods: National data will be collected from the verified 2016-2019 Danish OHCA register, and cases with FBAO prior to OHCA will selected via a direct marking by external validation and advanced text search. Patients reported as indisputably deceased (late signs of death) was excluded. Incidence rates per 100.000 citizens, survival rates to hospital and first aid actions by layperson are presented. A pilot study have been conducted in regional data from 2016-2019 and the study group have concluded that, a national study is feasible with the current amount of data and the used methodology. Expected outcome: This study will enable targeted campaigns aimed at increasing survival from OHCA caused by FBAO. Potential campaigns might target the food items provided to potential vulnerable groups and guide focus for first aid recommendations. Further, with a deeper understanding of which airway management procedures most often are successful, it will be possible to improve EMS treatments of vulnerable groups. Finally, a novel method of extracting information from the electronic medical records will be developed creating the foundation for future works on other prehospital conditions

This is a pilot study to assess the utility of the automatic stenosis index quantification using 3D Slicer software (Computer-based Quantification). We will recruit three physicians to perform a similar analysis using video images of the same bronchoscopes images (Human-based Quantification). This study relates to the latter data collection.

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

The use of laryngeal mask airway or i-gel to manage airway may improve success rates, especially in difficult situations more than tracheal intubation.

The aim of this study is to assess the bronchodilator response of salbutamol on respiratory mechanics of healthy individuals, smokers and COPD with varying degrees of airway obstruction.

This study aims at :- detecting the prevelance of snoring and OSA in non-obese patients identify their diagnostic profile in order to provide proper management
