Filter by:The aim of our study is to observationally examine our unexpected difficult airway incidence and intervention times. In addition, it is aimed to discuss the clinical effect of a team specialized in airway intervention intervening in cases by call on the success of airway intervention. In this discussion, it is aimed to use the opinion-opposition method.
In patients with limited neck extension and mouth opening due to reasons including previous radiation therapy in the head and neck area or cervical spine pathology, tracheal intubation with direct laryngoscopy (DL) are challenging because of the difficulty in aligning the oral, pharyngeal, and laryngeal axes in order to visualize the cords. In contrast, video-laryngoscopes (VL) only require alignment of the pharyngeal and laryngeal axes, which lie along much more similar angles when compared with the oral axis. Thus, VL make tracheal intubation easier to accomplish in these patients. Good patient positioning also maximizes the chance of successful laryngoscopy and tracheal intubation. In difficult airway society 2015 guidelines, advantages of head-up positioning and ramping, which brings the patient's sternum onto the horizontal plane of the external auditory meatus (EAM), are highlighted. In the obese patient, the 'ramped' position should be used routinely because this improves the view during DL. This position is usually achieved by placing blankets or other devices under the patient's head and shoulders, but can also be achieved simply by configuring the operation room (OR) table into a back-up head elevated (BUHE) position. Significantly improved glottic views on DL have been reported with both obese and non-obese adult patients in BUHE position. However, the effect of this simple maneuver on laryngeal visualization with the VL in patients with limited neck extension and mouth opening has not been reported. The investigators hypothesized that BUHE position might improve laryngeal views and make intubation easier compared to the supine position with the VL in patients with simulated difficult airway (application of a cervical collar to limit mouth opening and neck movement).The investigator investigated primarily the improvement in visualization of the glottis and, secondarily, the ease of tracheal intubation after alignment of the EAM and sternal notch.

Comparison of cervical spine movement during intubation with the C-MAC Video Stylet to Flexible Bronchoscopy
In the previous study on mannekin, the investigators found stylet-assisted lifting of epiglottis is an useful technique on difficult airway (Cormack-Lehane grade IIIa, IIIb) without increasing subjective difficulty. It has no expenses other than the routine intubation process. Recently, the studies have proved that the bougie-assisted laryngoscopy can improve first pass intubation rate in the emergency department. However, bougie is a disposable device and may increased medical expenditure. The investigators will evaluate the safety of bougie and epiglottic lifting technique, as well as the first pass and overall success rate of intubation comparing to traditional video laryngoscopy and direct laryngoscopy.
We evaluate the GlideScope and lighted stylet for DLT intubation in terms of the intubation time, number of intubation attempts, difficulty in DLT advancement towards the glottis, postoperative sore throat and hoarseness, and hemodynamic responses during intubation in patients with predicted difficult airways.
Investigators aimed to compare the ease of use of the LMA protector and I-gel LMA for tracheal intubation with the Aintree catheter in our study. Laryngeal mask airway (LMA) protector is the second generation perilaryngeal seal type supraglottic airway tool. The I-gel LMA is the second generation uncuffed supraglottic airway device. The Aintree Intubation Catheter has been designed for assisted fiberoptic intubation and for uncomplicated, atraumatic endotracheal tube exchange.Both LMA types have a structure that permits endotracheal intubation. In cases of difficult intubation, these two LMA types can be used. In the literature, there is no study comparing these two LMA types using Aintree catheter.Difficult Airway Society (DAS) published a guide for tracheal intubation in 2011 using Aintree. According to this guide, LMA type LMA Supreme is the most unfavorable for this process. However, there is no research or recommendation on the type of LMA most suitable for use in the literature. In accordance with the data of this study, it will be tried to show which LMA type may be suitable for intubation with Aintree catheter in patients.
To investigate which shapes of stylet, hand techniques and possible condition that improve intubation successful rate and reduce the elapsed intubation time.
Comparison of various videolaryngoscope devices (Vividtrac™ and KingVision™) and direct laryngoscopy with Macintosh blade regarding laryngoscopy time, intubation time, intubation success rate, percentage of visible glottic opening (POGO score) in elective and acute clinical anaesthesiology practice.
This is a survey of airway codes, which are emergency mobile phone requests for anaesthetic help to manage acute airway crises in the hospital (out of theatre, out of Surgical Intensive Care Unit, SICU). The anaesthetists are doctors trained in advance airway management. Patients in the hospital may suffer airway crises e.g. airway obstruction or need for tracheal intubation (insertion of breathing tube) for various reasons. The on call SICU anaesthetists responds to the airway code by attending the patient in need and managing the patient at their own discretion. Airway management will depend on the anaesthetist's knowledge, skills and experience. it will also depend on the available airway equipment. We plan to evaluate airway codes for a 24 month period. Parameters include: type of incident; patient factors (including airway assessment); type of equipment used; anaesthetic drugs used; airway management chosen by the attending anaesthetist; and, airway complications.
