Comparison of Ultrasonographic and Anthropometric Measurements in Difficult Airway Evaluation

2019-10-31 14:29:41 | BioPortfolio


In this study, anthropometric measurements (clinical measurements) will be applied in all patient groups; expected (to be difficult to provide airway patency as a result of detailed history, physical examination and evaluation tests performed by an experienced anesthesiologist), and unexpected (although it was not predicted that a difficulty was encountered). And ultrasounographic measurements will be applied in all patients. The aim of this study is to evaluate the predictive accuracy of ultrasonographic measurements.


In the preoperative period, the following clinical tests will be performed before the patient arrives in the operating room and when the patient arrives, the measurements will be made by ultrasonography.

1. Mallampati classification

2. Determination of mouth opening (interinsizer distance)

3. Thyromental distance

4. Sternomental distance

Preoperative evaluation of the patients and clinical results of the airway tests (mentioned above) will be recorded. The cervical soft tissue thickness will be measured and recorded at 3 levels (thyrohyoid membrane, vocal cord, hyoid bone) with the help of ultrasonography (mentioned above). In addition, since all patients will be under general anesthesia, laryngoscopic images (laryngoscopic evaluation according to Cormack Lehane classification) routinely recorded on the anesthesia follow-up sheet will be recorded.

Medical and Biotech [MESH] Definitions

A type of oropharyngeal airway that provides an alternative to endotracheal intubation and standard mask anesthesia in certain patients. It is introduced into the hypopharynx to form a seal around the larynx thus permitting spontaneous or positive pressure ventilation without penetration of the larynx or esophagus. It is used in place of a facemask in routine anesthesia. The advantages over standard mask anesthesia are better airway control, minimal anesthetic gas leakage, a secure airway during patient transport to the recovery area, and minimal postoperative problems.

A form of bronchial disorder with three distinct components: airway hyper-responsiveness (RESPIRATORY HYPERSENSITIVITY), airway INFLAMMATION, and intermittent AIRWAY OBSTRUCTION. It is characterized by spasmodic contraction of airway smooth muscle, WHEEZING, and dyspnea (DYSPNEA, PAROXYSMAL).

A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the TRACHEA and the BRONCHI. This results in a floppy non-rigid airway making patency difficult to maintain.

The structural changes in the number, mass, size and/or composition of the airway tissues.

A congenital or acquired condition of underdeveloped or degeneration of CARTILAGE in the BRONCHI. This results in a floppy bronchial wall making patency difficult to maintain. It is characterized by wheezing and difficult breathing.
