Cricothyroidotomy Clinical Trial
Official title:
Evaluation of the Novel ScalpelCric Set for Cricothyrotomy Corresponding the Scalpel-Bougie Technique and Comparison With Two Further Techniques of Cricothyrotomy on a Plastic Laryngeal Model (A) and Comparison of the Novel ScalpelCric Set With Surgical Cricothyrotomy in a Porcine Laryngeal Model (B) Influence of Training (A+B) in a Simulation
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 plan to recruit medical students (University Mainz), paramedics (employed
in ambulance and rescue helicopter), trainee anaesthetists and consultants of the department
of anesthesiology from the university hospital Mainz. After written informed consent the
participants have to complete an pre-study questionnaire, than the participants get an
information sheet about the 3 techniques and the investigators show the participants a short
video demonstrating the different techniques. All participants have the opportunity to
practice one insertion with each method on a plastic laryngeal model.
After that the participants have to perform each technique on the plastic model and the
investigators measure the time from initially handling equipment to the final end-point,
which the investigators take as a successful placement of the endotracheal tube verified by a
fiberoptic position check.
