Filter by:Cricothyroid membrane (CTM) localization is a critical step prior to emergent surgical airway access. Ultrasound-guided localization of the CTM on the skin of the neck had been suggested prior to induction of general anesthesia so that a marked entry point can be used to quickly establish emergent front of neck access if required. In this prospective observational study, the investigators aim to determine the potential for migration of the CTM markings in the sagittal plane during neck repositioning.
According to the recently published german guidelines for the prehospital airway management regular training for cricothyroidotomy is recommended. Even though participants prefer animal or cadaver trainingmodels, it is not possible to perform this comprehensive for a large number of participants due to organizational requirements like food hygiene, limited shelf-life and preparation time and expense. Therefore the investigators modified an available for purchase cricothyroidotomy trainer (the AirSim Combo X) with everyday suitable and cost-effective utensils. As a control group the investigators used a conventional simple plastic model.
During a cannot ventilate cannot intubate situation surgical airway is the last rescue option. Especially in the prehospital setting the airway management seems to be more difficult than in a hospital setting. Nearly all emergency physicians have a limited experience with cricothyrotomy and it is a unclear what method should be taught for this lifesaving procedure, due to lack of data in humans. The aim of this study is to compare the performance of medical personnel (medical students, paramedics, trainee anaesthetists and consultants) in establishing an emergency surgical airway on a plastic laryngeal model and in a porcine laryngeal model using the Scalpel Bougie technique, the Seldinger technique and the common surgical technique. Furthermore the investigators want to elucidate whether the training of the 3 techniques has an influence in the decision making of the preferred technique in a subsequently simulated cannot ventilate cannot intubate scenario.
The Investigators aim to determine how easy it is for anaesthetists to identify the Cricothyroid membrane (CTM) in children and infants and whether ultrasound maybe useful in addition. The investigators aim to conduct a randomised single blinded trial to compare methods to detect the CTM. The first group of patients will be randomised to palpation of anatomical landmarks group. Prior to commencing the MRI scan the anaesthetist is timed to identify the CTM and then the trachea using a felt tip pen. A ficidual marker will be placed on the 2 marked areas. The second group of patients will be randomised to receive ultrasound. Prior to commencing the MRI scan the sonographer is timed to identify the CTM and then the trachea using a felt tip pen. A ficidual marker will be placed on the two marked areas.
