Filter by:The aim of the study was to determine the impact of the videolaryngoscope on reducing the time needed to intubate on a low-fidelity manikin for beginners. The investigators conducted a randomised crossover study, which took place in the simulation department of the medical school of Tunis. They used a low-fidelity manikin designed for learning airway management. The first part of our session consisted in a theoretical training. The second part was the practical training with procedural simulation.
The Aim of the study was to determine the impact of the videolaryngoscpe on the time needed to intubate. This was a Prospective, randomized, simple blinded study. The participants intubated patients for surgery under general anesthesia either with direct laryngoscpy or with videolaryngoscopy.
In this study, the investigators aim to evaluate the glottic visualization and time to intubation during laryngoscopy performed with the C-MAC VL size 1 Miller blade lifting the epiglottis or placing the tip of the blade on the base of the tongue (vallecula) in children younger than 2 years of age.
The study's primary aim is to develop and validate a multivariable diagnostic model for the prediction of difficult videolaryngoscopy (the 'PeDiAC classification') in children undergoing general anesthesia with tracheal intubation. The secondary aim is to compare the diagnostic performance of the PeDiAC-classification with the Cormack-Lehane classification.
The investigators will evaluate the endotracheal intubation using video laryngoscopy versus conventional direct laryngoscopy on intubation success, quantified by the number of intubation attempts. The question is important because video laryngoscopes are more expensive than conventional direct laryngoscopes. The additional cost might be justified if video systems improve intubation success and reduce airway trauma. But if they do not, the extra cost would not be justified
Before an anesthetic procedure, airway management is essential to ensure adequate ventilation and breathing of the patient during the entire surgical process. The preanesthetic evaluation of the airway allows for proper planning, facilitates the anticipation of human resources and necessary means to face the possible challenges in a safe and efficient way. Orofacial mask ventilation and endotracheal intubation are a crucial step in general anesthesia. Most of the time, management is not complicated, but when an unpredicted difficult airway occurs, it is currently one of the most important challenges to face as an anesthesiologist. These situations are rare as the prevalence of a difficult airway is approximately 2.2% of the general population. When there is a case of a difficult airway and adequate management is not achieved, very serious complications may occur including brain damage, cardio-respiratory arrest, aspiration of gastric content, traumatic airway injuries, tooth damage, unnecessary surgical access to keep the airway permeable or death. For these reasons, in anesthesia, an unforeseen difficult airway is considered a crisis situation. Therefore, a preoperative airway assessment is paramount. Traditional predictive tests evaluate multiple anthropometric characteristics in which the physical presence of the patient is mandatory. However, no test can currently predict a difficult airway based on a single characteristic nor in the patient's absence. Nowadays, the optimization of resources and new technologies have increased interest in developing new tests or methods for preoperatively assessing the difficulty of the airway and new methods of airway evaluation have been proposed. As recently demonstrated, the detection of a difficult airway depends not only on the morphology but also on functional traits of the airway. Some studies propose the analysis of voice parameters as a reflection of anatomical and functional features of the superior airway. The investigators propose that the analysis of voice characteristics could reflect the airway's anatomy and therefore the investigators will be able to predict a difficult airway, and this would enable the development of a voice-based assessment method which could have an promising role in facilitating telematic airway evaluation.
Check the intubation conditions during laryngoscopy without external mobilization of the larynx, with Sellick manoeuvre or with low paratracheal esophagal compression.
During anesthetic induction, the relevance of neuromuscular blockade (NMB) onset monitoring cannot be asserted and its superiority over waiting for a fixed delay (corresponding to pharmacokinetic knowledge of the neuromuscular blocking agent used) has not been proven. However, many studies have shown a large inter-individual variability on the delay of the NMB onset. The main objective of othe investigator's study is to compare the quality of laryngoscopy during intubation between the NMB onset monitoring and the expectation of a fixed delay after curarization
The aim of this study is to demonstrate the effect of C-Mac videolaryngoscopy with Miller Blade size 0 and 1 on the intubation conditions in children less than 2 years age with a roll inserted under the shoulders.
In more than one-in-five cases of out-of-hospital cardiac arrest, airways are blocked by vomit and blood. Sometimes, paramedics cannot clear the airway using methods they have been taught. If the airway cannot be cleared, the patient will die. Usually, these patients will have a breathing tube placed into their windpipe (intubation), as this provides protection from vomit and blood. To do this, the paramedic needs to be able to see the entrance to the windpipe. A new method of clearing the airway called SALAD has been used in patients to help insert a breathing tube, but it is not known whether the method can help paramedics. This study will use a manikin to see if paramedics can insert a breathing tube more often on their first attempt, using SALAD.
