For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions, such as multiple sclerosis (MS) plaques. [1] It was invented by Graeme Bydder, Joseph Hajnal, and Ian Young in the early 1990s. [2]
Sagittal view of anatomy of patient during tracheal intubation. Intubation (sometimes entubation) is a medical procedure involving the insertion of a tube into the body. Patients are generally anesthetized beforehand. Examples include tracheal intubation, and the balloon tamponade with a Sengstaken–Blakemore tube (a tube into the ...
A sagittal plane (also known as anteroposterior plane) is perpendicular to the ground, separating left from right. The median (or midsagittal) plane is the sagittal plane in the middle of the body; it passes through midline structures such as the navel and the spine. All other sagittal planes (also known as parasagittal planes) are parallel to it.
The Oxford English Dictionary indicates that sagittal in the sense of the sagittal suture along the vertex of the skull pre-dates other anatomical usage. [7] Sagittal axis or anterior-posterior axis is the axis perpendicular to the coronal plane, i.e., the one formed by the intersection of the sagittal and the transversal planes
In anaesthesia and advanced airway management, rapid sequence induction (RSI) – also referred to as rapid sequence intubation or as rapid sequence induction and intubation (RSII) or as crash induction [1] – is a special process for endotracheal intubation that is used where the patient is at a high risk of pulmonary aspiration.
The Simplified Airway Risk Index (SARI), or El-Ganzouri Risk Index (EGRI), is a multivariate risk score thought to estimate the risk of difficult tracheal intubation. The SARI score ranges from 0 to 12 points, where a higher number of points indicates a more difficult airway. A SARI score of 4 or above is thought to indicate a difficult ...
Cricoid pressure, also known as the Sellick manoeuvre or Sellick maneuver, is a technique used in endotracheal intubation to try to reduce the risk of regurgitation.The technique involves the application of pressure to the cricoid cartilage at the neck, thus occluding the esophagus which passes directly behind it.
The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .
