Cricothyroidotomy
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 establishing ...

Angioedema
Angioedema is an area of swelling (edema) of the lower layer of skin and tissue just under the skin or mucous membranes. The swelling may occur in the face, tongue, larynx, abdomen, or arms and legs. Often it is associated with hives, which are swelling within the upper skin. Onset is typically over minutes to hours. The underlying mechanism typically involves histamine or bradykinin. The version related to histamine is due to an allergic reaction to agents such as insect bites, foods, or medications. The version related to bradykinin may occur due to an inherited problem known as C1 esterase inhibitor deficiency, medications known as angiotensin-converting enzyme inhibitors, or a lymphoproliferative disorder. Treatment to protect the airway may include intubation or cricothyroidotomy. Histamine-related angioedema can be treated with antihistamines, corticosteroids, and epinephrine. In those with bradykinin-related disease a C1 esterase inhibitor, ecallantide, or icatibant m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percutaneous Transtracheal Ventilation
Percutaneous transtracheal ventilation is the delivery of oxygen to the lungs through an over-the-needle catheter inserted through the skin into the trachea using a high pressure gas source is considered a form of conventional ventilation.{{cite journal, vauthors=Mace SE, Khan N , title=Needle cricothyrotomy. , journal=Emerg Med Clin North Am , year= 2008 , volume= 26 , issue= 4 , pages= 1085–101, xi , pmid=19059102 , doi=10.1016/j.emc.2008.09.004 , url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=19059102 Percutaneous transtracheal ventilation may be mistaken for transtracheal jet ventilation, which is not considered conventional ventilation and refers to high-frequency ventilation High-frequency ventilation is a type of mechanical ventilation which utilizes a respiratory rate greater than four times the normal value.

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 ...
