Cricothyrotomy
A cricothyrotomy (also called cricothyroidotomy) is an incision made through the skin and cricothyroid membrane to establish a patent airway during certain life-threatening situations, such as airway obstruction by a foreign body, angioedema, or massive facial trauma. Cricothyrotomy is nearly always performed as a last resort in cases where other means of tracheal intubation are impossible or impractical. Compared with tracheotomy, cricothyrotomy is quicker and easier to perform, does not require manipulation of the cervical spine, and is associated with fewer complications. However, while cricothyrotomy may be life-saving in extreme circumstances, this technique is only intended to be a temporizing measure until a definitive airway can be established. Indications A cricothyrotomy is often used as an airway of last resort given the numerous other airway options available including standard tracheal intubation and rapid sequence induction which are the common means of establishi ...

Tracheal Intubation
Tracheal intubation, usually simply referred to as intubation, is the placement of a flexible plastic tube into the trachea (windpipe) to maintain an open airway or to serve as a conduit through which to administer certain drugs. It is frequently performed in critically injured, ill, or anesthetized patients to facilitate ventilation of the lungs, including mechanical ventilation, and to prevent the possibility of asphyxiation or airway obstruction. The most widely used route is orotracheal, in which an endotracheal tube is passed through the mouth and vocal apparatus into the trachea. In a nasotracheal procedure, an endotracheal tube is passed through the nose and vocal apparatus into the trachea. Other methods of intubation involve surgery and include the cricothyrotomy (used almost exclusively in emergency circumstances) and the tracheotomy, used primarily in situations where a prolonged need for airway support is anticipated. Because it is an invasive and uncomfortable me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cricothyroid Membrane
The cricothyroid ligament (also known as the cricothyroid membrane or cricovocal membrane) is a ligament in the neck. It connects the cricoid cartilage to the thyroid cartilage. It prevents these cartilages from moving too far apart. It is cut during an emergency cricothyrotomy to treat upper airway obstruction. Structure The cricothyroid ligament is composed of two parts: * the median cricothyroid ligament along the midline (a thickening of the cricothyroid membrane). It is a flat band of white connective tissue that connects the front parts of the contiguous margins of the cricoid and thyroid cartilages. It is a thick and strong ligament, narrow above and broad below. Each lateral ligament is known as the conus elasticus. * the lateral cricothyroid ligaments on each side (these are also called conus elasticus). Each is overlapped on either side by laryngeal muscles. The conus elasticus (which means elastic cone in Latin) is the lateral portion of the cricothyroid ligament. Th ...

Tracheotomy
Tracheotomy (, ), or tracheostomy, is a surgical airway management procedure which consists of making an incision (cut) on the anterior aspect (front) of the neck and opening a direct airway through an incision in the trachea (windpipe). The resulting stoma (hole) can serve independently as an airway or as a site for a tracheal tube or tracheostomy tube to be inserted; this tube allows a person to breathe without the use of the nose or mouth. Etymology and terminology The etymology of the word ''tracheotomy'' comes from two Greek words: the root ''tom-'' (from Greek τομή ''tomḗ'') meaning "to cut", and the word ''trachea'' (from Greek τραχεία ''tracheía''). The word ''tracheostomy'', including the root ''stom-'' (from Greek στόμα ''stóma'') meaning "mouth," refers to the making of a semi-permanent or permanent opening, and to the opening itself. Some sources offer different definitions of the above terms. Part of the ambiguity is due to the uncertainty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

I Saw What I Saw (Grey's Anatomy Episode)
"I Saw What I Saw" is the sixth episode of the sixth season of the American television medical drama ''Grey's Anatomy'', and the show's 108th episode overall. It was written by Peter William Harper and directed by Allison Liddi-Brown. The episode was originally broadcast on the American Broadcasting Company (ABC) in the United States on October 22, 2009. The episode begins ''in medias res'', depicting events following a whodunit style, exposing them from alternating points of view in a fast-paced way. Katherine Heigl ( Dr. Izzie Stevens) was absent from the episode, due to her hiatus to film the 2010 romantic comedy '' Life as We Know It''. Upon its initial airing, the episode was viewed by 15.40 million people, garnered a 5.6/4 Nielsen rating/share in the 18–49 demographic, and ranked #1 for the night in terms of viewership and ratings. Plot After victims burned in a hotel fire are brought to the hospital, Seattle Grace and Mercy West residents compete to get the best ca ...

Rapid Sequence Induction
In 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 – is a special process for endotracheal intubation that is used where the patient is at a high risk of pulmonary aspiration. It differs from other techniques for inducing general anesthesia in that several extra precautions are taken to minimize the time between giving the induction drugs and securing the tube, during which period the patient's airway is essentially unprotected. One important difference between RSI and routine tracheal intubation is that the anesthesiologist does not typically manually assist the ventilation of the lungs after the onset of general anesthesia and cessation of breathing, until the trachea has been intubated and the cuff has been inflated. Uses This procedure is used where general anesthesia must be induced before the patient has had time to fast long enough to ...

Facial Trauma
Facial trauma, also called maxillofacial trauma, is any physical trauma to the face. Facial trauma can involve soft tissue injuries such as burns, lacerations and bruises, or fractures of the facial bones such as nasal fractures and fractures of the jaw, as well as trauma such as eye injuries. Symptoms are specific to the type of injury; for example, fractures may involve pain, swelling, loss of function, or changes in the shape of facial structures. Facial injuries have the potential to cause disfigurement and loss of function; for example, blindness or difficulty moving the jaw can result. Although it is seldom life-threatening, facial trauma can also be deadly, because it can cause severe bleeding or interference with the airway; thus a primary concern in treatment is ensuring that the airway is open and not threatened so that the patient can breathe. Depending on the type of facial injury, treatment may include bandaging and suturing of open wounds, administration of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicolas Roeg
Nicolas Jack Roeg (; 15 August 1928 – 23 November 2018) was an English film director and cinematographer, best known for directing ''Performance'' (1970), '' Walkabout'' (1971), ''Don't Look Now'' (1973), '' The Man Who Fell to Earth'' (1976), '' Bad Timing'' (1980), and '' The Witches'' (1990). Making his directorial debut 23 years after his entry into the film business, Roeg quickly became known for an idiosyncratic visual and narrative style, characterized by the use of disjointed and disorienting editing. For this reason, he is considered a highly influential filmmaker, cited as an inspiration by such directors as Steven Soderbergh, Christopher Nolan, and Danny Boyle. In 1999, the British Film Institute acknowledged Roeg's importance in the British film industry by respectively naming ''Don't Look Now'' and ''Performance'' the 8th and 48th greatest British films of all time in its Top 100 British films poll. Early life Roeg was born in St John's Wood in North London ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
