Which organ is affected when a person suffer from laryngeal edema?
Laryngeal edema is a common feature of acute inflammation, but it is particularly important because swelling of the epiglottis and vocal cords can obstruct the laryngeal orifice, resulting in asphyxiation.

How long can an ET tube stay in?
Can a cuff leak test be used to identify high risk patients?
Although patients at low risk for postextubation respiratory insufficiency due to laryngeal edema can be identified by the cuff leak test or laryngeal ultrasound, no reliable test for the identification of high-risk patients is currently available.
What is PLE after extubation?
The edema results in a decreased size of the laryngeal lumen, which may present as stridor or respiratory distress (or both) following extubation. Ultimately, postextubation laryngeal edema (PLE) may lead to respiratory failure with subsequent need for reintubation. Since reintubation is associated with increased morbidity and mortality, ...
Can laryngeal edema cause respiratory failure?
Ultimately, postextubation laryngeal edema (PLE) may lead to respiratory failure with subsequent need for reintubation. Since reintubation is associated with increased morbidity and mortality, it is important to prevent reintubation if possible [3].
What are the risk factors for PLE?
Important risk factors include female gender, longer duration of intubation, use of large tube size and high cuff pressure, and difficult intubation. Unfortunately, none of these risk factors is sufficiently reliable to identify patients at risk for PLE and this prevents targeted treatment of high-risk patients.
What is the complication of intubation?
Laryngeal edema is a frequent complication of intubation. It often presents shortly after extubation as post-extubation stridor and results from damage to the mucosa of the larynx. Mucosal damage is caused by pressure and ischemia resulting in an inflammatory response.
Can a positive cuff leak test cause laryngeal edema?
Several studies show that a positive cuff leak test combined with the presence of risk factors can identify patients with increased risk for laryngeal edema.
Can laryngeal edema cause stridor?
On the other hand, laryngeal edema represents a common cause for breathing difficulty and/or stridor following extubation, thereby makes a common etiology for extubation failure and the need for reintubation.
Why is post-intubation laryngeal edema important?
Thus, because reintubation is associated with augmented morbidity and mortality, the issue of post-intubation laryngeal edema is of paramount importance and needs for careful prevention and proper management .
What is the laryngeal injury?
Laryngeal injuries are common after endotracheal intubation, which could manifest as varying degrees of edema, ulceration, granulation, and restricted vocal cord mobility, often resulting in luminal narrowing. Among these conditions, laryngeal edema is a common complication following intubation and usually results from the direct pressure and the inflammatory reaction triggered by the endotracheal tube on surfaces of contact.
How long does edema last after RT?
In patients irradiated for carcinoma of the glottis, the incidence of mild to moderate laryngeal edema persisting for more than 3 months after RT is about 10% to 25%. 100,192,194 The incidence of severe laryngeal edema is about 1.5% to 4.6%. 62,97,111,116,174 The incidence of laryngeal edema increases with greater total dose, field size, dose per fraction, and T stage of the lesion. * A randomized study found that persistent laryngeal edema occurred in 4% of the patients treated with 5 × 5–cm 2 fields and in 21% of the patients with 6 × 6–cm 2 fields and no difference in local control in the two arms. 174
Why is laryngeal edema so common?
Laryngeal edema is a common feature of acute inflammation, but it is particularly important because swelling of the epiglottis and vocal cords can obstruct the laryngeal orifice, resulting in asphyxiation . Laryngeal edema occurs in pigs with edema disease; in horses with purpura hemorrhagica; in cattle with acute interstitial pneumonia; in cats with systemic anaphylaxis; and in all species as a result of trauma, improper endotracheal tubing, inhalation of irritant gases (e.g., smoke), local inflammation, and allergic reactions. Grossly, the mucosa of the epiglottis and vocal cords is thickened and swollen, often protrudes dorsally onto the epiglottic orifice, and has a gelatinous appearance ( Fig. 9-43 ).
What causes laryngeal edema in cats?
Laryngeal edema occurs in pigs with edema disease; in horses with purpura hemorrhagica; in cattle with acute interstitial pneumonia; in cats with systemic anaphylaxis; and in all species as a result of trauma, improper endotracheal tubing, inhalation of irritant gases (e.g., smoke), local inflammation, and allergic reactions.
What is the cause of post-extubation edema?
Laryngeal edema is an important cause of post-extubation obstruction, especially in neonates and infants. This condition has various causes and is classified as supraglottic, retroarytenoidal, or subglottic. 315 Supraglottic edema most commonly results from surgical manipulation, positioning, hematoma formation, overaggressive fluid management, impaired venous drainage, or coexisting conditions (e.g., preeclampsia, angioneurotic edema). Retroarytenoidal edema typically results from local trauma or irritation. Subglottic edema occurs most often in children, particularly neonates and infants. Factors associated with development of subglottic edema include traumatic intubation, intubation lasting longer than 1 hour, bucking on the ETT, changes in head position, or tight-fitting tubes. Laryngeal edema usually manifests as stridor within 30 to 60 minutes after extubation, although it may start as late as 6 hours after extubation. Regardless of the cause of laryngeal edema , management depends on the severity of the condition. Therapy consists of humidified oxygen, nebulized epinephrine, head-up positioning, and occasionally reintubation with a smaller ETT. The practice of administering parenteral steroids with the goal of preventing or reducing edema after long-term (>36 hours) ventilation may prove beneficial for adult patients, but routine administration for anesthesia is controversial. 316
What causes subglottic edema in children?
Factors associated with development of subglottic edema include traumatic intubation, intubation lasting longer than 1 hour, bucking on the ETT, changes in head position, or tight-fitting tubes.
How long does it take for edema to manifest after extubation?
Laryngeal edema usually manifests as stridor within 30 to 60 minutes after extubation, although it may start as late as 6 hours after extubation. Regardless of the cause of laryngeal edema, management depends on the severity of the condition.
Why is no biopsy done for arytenoids?
If it is mild and stable, if no visible recurrence develops, and especially if it is limited to the arytenoids, no biopsy is attempted because of the risk of inducing laryngeal necrosis.
