Filter by:The study is designed to evaluate the validity of the SMDD as a predictor of difficult airway in elderly and to compare its validity with that of the TMHT.
In this study, it was planned to evaluate the preoperative neck ultrasonography measurements as a predictor of difficult airway in adult patients who will undergo elective surgery under general anesthesia.
Flexible bronchoscope or videoscope plays important roles in managing difficult airway. But this technique is time-consuming and very difficult to learn for novices. The investigators design a simple training simulator to help them master this technique.
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.
Intrabronal intubation is one of the basic methods of airway protection during cardiac surgery. The use of double-lumen tubes in the implementation of a standard method based on macintosh laryngoscope may cause the prolongation of the procedure especially in the case of difficult airways. The aim of the study was to match the effectiveness of endotracheal intubation using a standard Macontosh laryngskop and a normal double-lumen tube versus the ETView DL tube.
When difficult airway/intubation occurs in the OR the anesthesiologist needs rescue techniques and equipment. The algorithms about management of the difficult airway don't provide adequate data. In current study researchers aim to determine most preferred rescue techniques and success rate of the chosen technique.
The incidence of difficult airway in paediatric population is up-to date not well described. Difficult airway is connected with significant airway-related morbidity and mortality. The majority of difficult airway in paediatric patients should be predictable. The aim of the study is to evaluate the incidence of difficult airway in paediatric patients scheduled for surgery under general anaesthesia and to test the predictability of the set of prediction tests to reveal the patients with high risk of difficult airway.
Supraglottic airway tools, one of the tools used in the management of the difficult airway. American Society of Anesthesiologists and the Difficult Airway Society of the United Kingdom airway management algorithms have included the LMA. In our study investigators aimed to determine which one will show the best performance with supraglottic airway means that LMA - Classic, LMA - Flexible and LMA - ProSeal in patients that difficult airway scenarios created with attaching collar.
The F.R.O.N.T. formula for pre-operative airway assessment and documentation Background: Prediction of difficult airway is one of the most important challenges before general anesthesia. Although in recent decades different scoring systems have been for the preoperative assessment of their sensitivity and specificity in predicting a difficult airway remains moderate. Recently, the calculation of composite scores using different formulae has been proposed as the most sensitive one. The aim of the present work was to test the clinical usefulness of the FRONT score, a recently developed scoring system. Methods: This study was a multi-center, inter-observer, prospective and double-blind investigation that included 976 patients from two university centers: 250 from the University of Cluj-Napoca, Romania, and 726 from the University of Debrecen, Hungary. The preoperative evaluation of the patients was performed by a preoperative team of anesthesiologists (team A) who evaluated and scored the expected difficulty of the management of the airway. An intraoperative team of evaluators (team B) working independently from team A, performed the actual instrumentation of the airway and scored the actual findings. Both teams used the FRONT scoring system and worked independently from each other to ensure blinded assessment. Statistical analysis of the preoperative and intraoperative FRONT scores were performed post hoc.
Infants (0-1 yr.) with anticipated difficult airways will be enrolled in the study. Specifically, we will include infants with cleft palate, Pierre Robin, Treacher Collins, trisomy 21, or similar congenital malformations. Patients with American Society of Anesthesiologists physical status scores ≥3 will be excluded, as will those with congenital heart disease and left-to-right shunting. Patients will be randomly assigned to laryngoscopy with or without simultaneous insufflation of oxygen at 4 L/minute. Oxygen will be provided by a flowmeter connected via rigid tubing to the track-mounted endotracheal tube on the AirTraq. Randomization (1:1) will be based on computer-generated codes with random block sizes and stratified by hospital; allocation will be concealed and provided to clinicians via a secure web site that will be accessed shortly before induction of anesthesia.
