Airway management includes a set of maneuvers and medical procedures performed to both prevent and relieve airway obstruction. This ensures an open pathway for gas exchange between a patient's lungs and the atmosphere.[1] This is accomplished by either clearing a previously obstructed airway, which can be caused by the tongue, foreign objects, the tissues of the airway itself, and bodily fluids such as blood and gastric contents (aspiration), or by preventing airway obstruction in cases such as anaphylaxis, the obtunded patient, or medical sedation.

Airway management is commonly divided into two categories: basic and advanced.

Basic techniques are generally non-invasive and do not require specialized medical equipment or advanced training. These include head maneuvers to optimize ventilation, abdominal thrusts, and back blows.

Advanced techniques require specialized medical training and equipment, and are further categorized anatomically into supraglottic devices (such as oropharyngeal and nasopharyngeal airways), infraglottic techniques (such as tracheal intubation), and surgical methods (such as cricothyrotomy).[2]

Airway management is a primary consideration in cardiopulmonary resuscitation, anaesthesia, emergency medicine, intensive care medicine, and first aid. It represents the "A" In the ABC treatment mnemonic.[3]

Basic airway management

Main article: Basic airway management

Basic airway management is mainly used in first aid since it is non-invasive, simple to perform and does not rely on the use of medical equipment (in contrast to advanced airway management). Basic airway management can be divided into treatment and prevention.[citation needed] The simplest way to determine if the airway is obstructed is by assessing whether the patient is able to speak.[4]

Back slaps and abdominal thrusts are performed to relieve airway obstruction by foreign objects
Inward and upward force during abdominal thrusts

Treatment

Treatment includes a number of maneuvers aimed at removing foreign bodies from the airways. This most often occurs when someone is eating or drinking. Most modern protocols, including those of the American Heart Association, American Red Cross and the European Resuscitation Council,[5] recommend several stages, designed to apply increasingly more pressure. Most protocols recommend first encouraging the victim to cough, and allowing them an opportunity to spontaneously clear the foreign body if they are coughing forcefully. If the person's airway continues to be blocked, more forceful maneuvers such as hard back slaps and abdominal thrusts (Heimlich maneuver) can be performed. Some guidelines recommend alternating between abdominal thrusts and back slaps while others recommend starting with back slaps first.[5]

Performing abdominal thrusts on someone else involves standing behind them, and providing and inward and upward force in the upper abdomen. Abdominal thrusts can also be performed on oneself with certain objects, such as by leaning over a chair. In adults, there is limited evidence that the head down position can be used for self-treatment of suffocation and appears to be an option only if other maneuvers do not work.[6] In contrast, in children under 1 it is recommended that the child be placed in a head down position as this appears to help increase the effectiveness of back slaps and abdominal thrusts.[7]

The American Medical Association advocates sweeping the fingers across the back of the throat to attempt to dislodge airway obstructions, once the choking victim becomes unconscious.[8] However, many modern protocols recommend against the use of the finger sweep since. If the person is conscious, they should be able to remove the foreign object themselves, and if they are unconscious, a finger sweep can cause more harm. A finger sweep can push the foreign body further down the airway, making it harder to remove, or cause aspiration by inducing the person to vomit. Additionally, there is the potential for harm to the rescuer if they are unable to clearly see the oral cavity (for example, cutting a finger on jagged teeth).

Prevention

The head-tilt/chin-lift is the most reliable method of opening the airway.
The jaw thrust maneuver can also open up the airway with minimal spine manipulation

Prevention techniques focus on preventing airway obstruction by the tongue and reducing the likelihood of aspiration of stomach contents or blood. The head-tilt/chin-lift and jaw-thrust maneuvers are useful for the former while the recovery position is useful for the latter. If head-tilt/chin-lift and jaw-thrust maneuvers are performed with any objects in the airways it may dislodge them further down the airways and thereby cause more blockage and harder removal.[citation needed]

The head-tilt/chin-lift is the primary maneuver used in any patient in whom cervical spine injury is not a concern. This maneuver involves extension of the neck and flexion of the head (also called the sniffing position), which opens up the airway by lifting the tongue away from the back of the throat. Placing a folded towel behind the head accomplishes the same result.[4]

All forms of the recovery position share basic principles. The mouth is downward so that fluid can drain from the patient's airway; the chin is well up to keep the epiglottis opened. Arms and legs are locked to stabilize the position of the patient

The jaw-thrust maneuver is an effective airway technique, particularly in the patient in whom cervical spine injury is a concern. It is easiest when the patient is positioned supine. The practitioner places their index and middle fingers behind the angle of the mandible to physically push the posterior aspects of the mandible upwards while their thumbs push down on the chin to open the mouth. When the mandible is displaced forward, it pulls the tongue forward and prevents it from occluding the entrance to the trachea.[citation needed]

The recovery position refers to one of a series of variations on a lateral recumbent or three-quarters prone position of the body, in to which an unconscious but breathing casualty can be placed. Use of the recovery position prevents aspiration.[citation needed]

Most airway maneuvers are associated with some movement of the cervical spine.[9][10] Even though collars for holding the head in-line can cause problems maintaining an airway and maintaining a blood pressure,[11] it is not recommended to remove the collar without adequate personnel to manually hold the head in place.[12]

Advanced airway management

Main article: Advanced airway management

In contrast to basic airway management maneuvers such as head-tilt or jaw-thrust, advanced airway management relies on the use of medical equipment. Advanced airway management can be performed "blind" or with visualization of the glottis e.g. by the use of a laryngoscope. 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.[citation needed]

In increasing order of invasiveness are the use of supraglottic devices such as oropharyngeal or nasopharyngeal airways, followed by infraglottic techniques such as tracheal intubation and finally surgical methods[citation needed]

Removal of foreign objects

Foreign objects can be removed with a Magill forceps under inspection of the airway with a laryngoscope

The ingestion and aspiration of foreign objects poses a common and dangerous problem in young children. It remains one of the leading cause of death in children under the age of 5.[13] Common food items (baby carrots, peanuts, etc.) and household objects (coins, metals, etc.) may lodge in various levels of the airway tract and cause significant obstruction of the airway. Complete obstruction of the airway represents a medical emergency. During such crisis, caretakers may attempt back blows, abdominal thrust, or the Heimlich maneuver to dislodge the inhaled object and reestablish airflow into the lungs.[14]

In the hospital setting, healthcare practitioners will make the diagnosis of foreign body aspiration from the medical history and physical exam findings. In some cases, providers will order chest radiographs, which may show signs of air-trapping in the affected lung. In advanced airway management, the inhaled foreign objects, however, are either removed by blind suction or under direct inspection of the airway with a laryngoscope or bronchoscope. If removal is not possible, other surgical methods should be considered.[15]

Supraglottic techniques

Supraglottic techniques employ the use of supraglottic devices that are designed to have the distal tip above the level of the glottis when in it's final resting position with the goal of ensuring patency of the upper respiratory tract without entry into the trachea.[citation needed] There are many methods of subcategorizing this family of devices including route of insertion, absence or presence of a cuff, and anatomic location of the device's distal end.[citation needed] The most commonly used devices are laryngeal masks or supraglottic tubes, such as oropharyngeal (OPA) and Nasopharyngeal airways (NPA) which are further described below. In general, features of an ideal supraglottic airway include the ability to bypass the upper airway, easy insertion even by a nonspecialist, high first-time insertion rate, stability once in seated position, minimal to no risk of aspiration, disposability to prevent risk of cross-infection, and minimal side effects.[citation needed]

A nasopharyngeal airway is a soft rubber or plastic tube that is passed through the nose and into the posterior pharynx. Patients tolerate NPAs more easily than OPAs, so NPAs can be used when the use of an OPA is difficult, such as when the patient's jaw is clenched or the patient is semiconscious and cannot tolerate an OPA.[16] NPAs are generally not recommended if there is suspicion of a fracture to the base of the skull, due to the possibility of the tube entering the cranium.[17] However, the actual risks of this complication occurring compared to the risks of damage from hypoxia if an airway is not used are debatable.[17][18]

Oropharyngeal airways in a range of sizes

Oropharyngeal airways are curved, rigid plastic devices, inserted into the patient's mouth. OPAs prevent airway obstruction by ensuring that the patient's tongue does not obstruct the epiglottis. Because an oropharyngeal airway can mechanically stimulate the gag reflex, it should only be used in a deeply sedated or unresponsive patient to avoid vomiting and aspiration .[19]

Supraglottic airways (or extraglottic devices[20]) are a family of devices that are inserted through the mouth to sit on top of the larynx. Supraglottic airways are used in the majority of operations performed under general anaesthesia.[21] Compared to a cuffed tracheal tube (see below), they give less protection against aspiration but are easier to insert and cause less laryngeal trauma.[20] The best-known example is the Laryngeal Mask Airway or LMA™. A laryngeal mask airway is an airway placed into the mouth and set over the glottis and inflated.[22] Other variations include devices with oesophageal access ports, so that a separate tube can be inserted from the mouth to the stomach to decompress accumulated gases and drain liquid contents.[20] Some devices can have an endotracheal tube passed through them into the trachea.[20]

Infraglottic techniques

A cuffed endotracheal tube used in tracheal intubation

Unlike supraglottic devices; infraglottic devices pass through the glottis and thereby enter the trachea. Tracheal intubation, often simply referred to as intubation, is the placement of a flexible plastic or rubber tube into the trachea to maintain an open airway or to serve as a conduit through which to administer certain drugs. 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.Alternatives to standard endotracheal tubes includes laryngeal tube and combitube.[citation needed]

Surgical methods

Main article: surgical airway management
In cricothyrotomy, the incision or puncture is made through the cricothyroid membrane in between the thyroid cartilage and the cricoid cartilage
In cricothyrotomy, the incision or puncture is made through the cricothyroid membrane in between the thyroid cartilage and the cricoid cartilage

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. Surgical methods for airway management include cricothyrotomy and tracheostomy.[citation needed]

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.[23] 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 immediate complications.[24]

A tracheotomy is a surgically created opening from the skin of the neck down to the trachea.[25] A tracheotomy may be considered where a person will need to be on a mechanical ventilator for a longer period.[25] The advantages of a tracheotomy include less risk of infection and damage to the trachea during the immediate post-surgical period.[25] Although rare, some long term complications of tracheotomies include tracheal stenosis and tracheoinnominate fistulas.[26]

Airway management in specific situations

Cardiopulmonary resuscitation

Main article: Cardiopulmonary resuscitation

The optimal method of airway management during CPR is not well established at this time given that the majority of studies on the topic are observational in nature. These studies, however, guide recommendations until prospective, randomized controlled trials are conducted.

Current evidence suggests that for out-of-hospital cardiac arrest, basic airway interventions (head-tilt–chin-lift maneuvers, bag-valve-masking or mouth-to-mouth ventilations, nasopharyngeal and/or oropharyngeal airways) resulted in greater short-term and long-term survival, as well as improved neurological outcomes in comparison to advanced airway interventions (endotracheal intubation, laryngeal mask airway, all types of supraglottic airways (SGA), and trans-tracheal or trans-cricothyroid membrane airways).[27][28] Given that these are observational studies, caution must be given to the possibility of confounding by indication. That is, patients requiring an advanced airway may have had a poorer prognosis in relation to those requiring basic interventions to begin with.

For the management of in-hospital cardiac arrest however, studies currently support the establishment of an advanced airway. It is well documented that quality chest compressions with minimal interruption result in improved survival.[29] This is suggested to be due, in part, to decreased no-flow-time in which vital organs, including the heart are not adequately perfused. Establishment of an advanced airway (endotracheal tube, laryngeal mask airway) allows for asynchronous ventilation, reducing the no-flow ratio, as compared to the basic airway (bag-valve mask) for which compressions must be paused to adequately ventilate the patient.[30]

Bystanders without medical training who see an individual suddenly collapse should call for help and begin chest compressions immediately. The American Heart Association currently supports "Hands-only"™ CPR, which advocates chest compressions without rescue breaths for teens or adults.[31] This is to minimize the reluctance to start CPR due to concern for having to provide mouth-to-mouth resuscitation.

Trauma

Airway represents the "A" in the ABC mnemonic for trauma resuscitation.

Management of the airway in trauma can be particularly complicated, and is dependent on the mechanism, location, and severity of injury to the airway and its surrounding tissues. Injuries to the cervical spine, traumatic disruption of the airway itself, edema in the setting of caustic or thermal trauma, and the combative patient are examples of scenarios a provider may need to take into account in assessing the urgency of securing an airway and the means of doing so.[32][33]

The pre-hospital setting provides unique challenges to management of the airway including tight spaces, neck immobilization, poor lighting, and often the added complexity of attempting procedures during transport. When possible, basic airway management should be prioritized including head-tilt-chin-lift maneuvers, and bag-valve masking. If ineffective, a supraglottic airway can be utilized to aid in oxygenation and maintenance of a patent airway. An oropharyngeal airway is acceptable, however nasopharyngeal airways should be avoided in trauma, particularly if a basilar skull fracture is suspected.[34] Endotracheal intubation carries with it many risks, particularly when paralytics are used, as maintenance of the airway becomes a challenge if intubation fails. It should therefore be attempted by experienced personnel, only when less invasive methods fail or when it is deemed necessary for safe transport of the patient, to reduce risk of failure and the associated increase in morbidity and mortality due to hypoxia.[35][36]

Management of the airway in the emergency department is optimal given the presence of trained personnel from multiple specialties, as well as access to "difficult airway equipment" (videolaryngoscopy, eschmann tracheal tube introducer, fiberoptic bronchoscopy, surgical methods, etc.).[4] Of primary concern is the condition and patency of the maxillofacial structures, larynx, trachea, and bronchi as these are all components of the respiratory tract and failure anywhere along this path may impede ventilation. Excessive facial hair, severe burns, and maxillofacial trauma may prevent acquisition of a good mask seal, rendering bag-valve mask ventilation difficult. Edema of the airway can make laryngoscopy difficult, and therefore in those with suspected thermal burns, intubation is recommended in attempts to quickly secure an airway prior to progression of the swelling.[37] Furthermore, blood and vomitus in the airway may prove visualization of the vocal cords difficult rendering direct and video laryngoscopy, as well as fiberoptic bronchoscopy challenging.[38] Establishment of a surgical airway is challenging in the setting of restricted neck extension (such as in a c-collar), laryngotracheal disruption, or distortion of the anatomy by a penetrating force or hematoma. Tracheotomy in the operating room by trained professionals is recommended over cricothyroidotomy in the case of complete laryngotracheal disruption or children under the age of 12.[39]
