Ultrasonography Versus Palpation for Identification of the Cricothyroid Membrane

2016-11-30 15:45:45 | BioPortfolio


After a structured teaching program anaesthetists are educated in identifying the cricothyroid membrane with ultrasonography. Thereafter their ability to do so is compared with their ability to do so with palpation. In an obese volunteer


After a structured teaching program anaesthetists are educated in identifying the cricothyroid membrane with ultrasonography. Thereafter their ability to do so is compared with their ability to do so with palpation.

The purpose is to advise a propriety method for preanesthetic identification. In an obese volunteer

Study Assessing the Position of Cricothyroid Membrane in Relation to Movement of Neck From Neutral to Extended Position

Ability to provide oxygen to patients undergoing general anaesthesia is crucial. This is traditionally provided using face mask, supraglottic airway (breathing tube above voice box) or end...

Do SGAs Improve Identification of the CTM

Prospective, observational, non-interventional study that will examine if the insertion of a Supraglottic airway will increase accuracy of identifying the cricothyroid membrane

Study to Determine if Tissue Scored With a Scalpel Results in Any Noticeable Marks

Mohs Micrographic Surgery is a well established method for treatment of cutaneous malignancies. Part of this technique requires marking skin surrounding the tumor. There are two ways of ma...

Measurement of Recirculation During Venovenous Extracorporeal Membrane Oxygenation (VV ECMO)

This study is to test the usefulness of ultrasound dilution recirculation measurements in patients receiving venovenous extracorporeal membrane oxygenation as therapy. The ultrasound dilut...

Study of beta2-Microglobulin Removal by Standard Versus New High Cut-Off Haemodialysis Membrane

The purpose of this study is to determine whether a novel haemodialysis membrane, compared with the standard dialysis membrane, will increase the removal of beta2-microglobulin in chronic ...

Influences of Phonological Context on Tense Marking in Spanish-English Dual Language Learners.

The emergence of tense-morpheme marking during language acquisition is highly variable, which confounds the use of tense marking as a diagnostic indicator of language impairment in linguistically dive...

Grammatical case-marking in Japanese children with SLI.

The purpose of this study was to investigate whether or not Japanese children with specific language impairment (henceforth; SLI) would in fact experience difficulty with grammatical case-marking. The...

Feasibility of laser marking in Barrett's esophagus with Volumetric laser endomicroscopy First-in-man pilot study.

Volumetric laser endomicroscopy (VLE) provides a circumferential scan of the esophageal wall layers, and has potential to improve neoplasia detection in Barrett's esophagus (BE). The novel VLE laser m...

Comparison of wire-guided localization and radio-guided occult lesionlocalization in preoperative localization of nonpalpable breast lesions.

Breast lesions that are not palpable on physical examination but considered suspicious for malignancy on mammography or ultrasonography should be marked before surgery. Wire-guided localization (WGL) ...

Microbubble-Assisted Ultrasound-Induced Transient Phosphatidylserine Translocation.

Microbubble-assisted ultrasound (sonopermeabilization) results in reversible permeabilization of the plasma membrane of cells. This method is increasingly used in vivo because of its potential to del...

Medical and Biotech [MESH] Definitions

Branches of the VAGUS NERVE. The superior laryngeal nerves originate near the nodose ganglion and separate into external branches, which supply motor fibers to the cricothyroid muscles, and internal branches, which carry sensory fibers. The RECURRENT LARYNGEAL NERVE originates more caudally and carries efferents to all muscles of the larynx except the cricothyroid. The laryngeal nerves and their various branches also carry sensory and autonomic fibers to the laryngeal, pharyngeal, tracheal, and cardiac regions.

Any system of defining ownership of dentures or dental prostheses.

The pit in the center of the ABDOMINAL WALL marking the point where the UMBILICAL CORD entered in the FETUS.

The marking of biological material with a dye or other reagent for the purpose of identifying and quantitating components of tissues, cells or their extracts.

The indelible marking of TISSUES, primarily SKIN, by pricking it with NEEDLES to imbed various COLORING AGENTS. Tattooing of the CORNEA is done to colorize LEUKOMA spots.
