Surgical airway management

Surgical airway management is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Surgical airway management rather than just read about it. In short: Surgical airway management (bronchotomy) is the medical procedure ensuring an open airway between a patient's lungs and the outside world. Surgical methods for airway management rely on making a surgical incision below the glottis in order to achieve direct access to the lower respiratory tract, bypassing the upper respiratory tract.

Key takeaways

Surgical airway management belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Surgical airway management to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Surgical airway management from memory before moving on to harder problems.

Reference excerpt

Surgical airway management (bronchotomy) is the medical procedure ensuring an open airway between a patient's lungs and the outside world. Surgical methods for airway management rely on making a surgical incision below the glottis in order to achieve direct access to the lower respiratory tract, bypassing the upper respiratory tract. Surgical airway management is often performed as a last resort in cases where orotracheal and nasotracheal intubation are impossible or contraindicated. Surgical airway management is also used when a person will need a mechanical ventilator for a longer period. The surgical creation of a permanent opening in the larynx is referred to as laryngostomy. Surgical airway management is a primary consideration in anaesthesia, emergency medicine and intensive care medicine. Surgical methods for airway management include cricothyrotomy and tracheostomy

History Asclepiades of Bithynia is credited with being the first person who proposed bronchotomy as a surgical procedure, though he never attempted to perform one. Aretaeus of Cappadocia thought the procedure dangerous even as a remedy for choking, since the resulting incision "would not heal, as being cartilaginous"; Caelius Aurelianus also rejected its usefulness.

Cricothyrotomy

A cricothyrotomy 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. A cricothyrotomy is nearly always performed as a last resort in cases where orotracheal and nasotracheal intubation are impossible or contraindicated. Cricothyrotomy is easier and quicker to perform than tracheotomy, does not require manipulation of the cervical spine and is associated with fewer complications.

Needle cricothyrotomy

A needle cricothyrotomy is similar to a cricothyrotomy, but instead of making a scalpel incision, a large over-the-needle catheter is inserted (10- to 14-gauge). This is considerably simpler, particularly if using specially designed kits. This technique provides very limited airflow. 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 called percutaneous transtracheal ventilation (PTV).

Tracheotomy

A tracheotomy is a surgically created opening from the skin of the neck down to the trachea. A tracheotomy may be considered where a person will need to be on a mechanical ventilator for a longer period. The advantages of a tracheotomy include less risk of infection and damage to the trachea such as tracheal stenosis.

Worked examples

Example 1 — a first encounter with Surgical airway management

Start with the simplest possible case. Write down what Surgical airway management claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Surgical airway management before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Surgical airway management ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Surgical airway management

In research: Surgical airway management appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Surgical airway management in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Surgical airway management is common in secondary-school and first-year university syllabi. It links to neighbouring topics Otorhinolaryngology, so understanding it makes those chapters shorter.
In everyday life: Look for Surgical airway management outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
