How does nebulized epinephrine help with croup?
Children with croup develop swelling of inner mucosal layers of the larynx and trachea. Nebulised adrenaline is thought to act by stimulating α-adrenergic receptors in subglottic mucous membranes, producing vasoconstriction and decreased mucosal oedema.
Why is racemic epinephrine contraindicated in epiglottitis?
Racemic epinephrine should be avoided because of the rebound effect. Awareness of the possibility of epiglottitis in adults and close monitoring of the airway are the keys to management of this potentially life-threatening condition.

What is the best treatment for upper airway obstruction?
Upper airway obstruction with stridor and edema should be treated with high-flow nebulized oxygen, racemic epinephrine, and IV epinephrine. If airway obstruction is severe or increases, bag-valve-mask–assisted ventilation, endotracheal intubation, or cricothyroidotomy should be performed.
How long does it take for dexamethasone to work?
With prolonged intubation (adults, 5 to 7 days; children, 1 to 2 weeks), consultation for endoscopic laryngeal assessment is advised. Minor injuries usually resolve spontaneously after removal of the endotracheal tube.
What is the narrowest part of the airway in neonates?
The subglottis is the narrowest portion of the airway in neonates. The presence of a foreign body, as occurs with prolonged intubation, produces edema in the subglottic region, which can produce further narrowing of the airway when the neonate is extubated. Racemic epinephrine stimulates both α- and β-adrenergic receptors. It acts on vascular smooth muscle to produce vasoconstriction, which markedly decreases blood flow at the capillary level. This shrinks upper respiratory mucosa and reduces edema. Racemic epinephrine is a useful agent in patients with established postextubation stridor; however, its efficacy for prevention of postextubation stridor has not been proven.177 Racemic epinephrine may also be considered as an adjunct to therapy for pulmonary hemorrhage. 178 When using racemic epinephrine, one should be aware of the side effects, which include tachycardia, arrhythmias, hypertension, peripheral vasoconstriction, hyperglycemia, hyperkalemia, metabolic acidosis, and leukocytosis. 177

Who discovered the adrenal gland?
Extracts of the adrenal gland were first obtained by Polish physiologist Napoleon Cybulski in 1895. These extracts, which he called nadnerczyna, contained adrenaline and other catecholamines. American ophthalmologist William H. Bates discovered adrenaline's usage for eye surgeries prior to 20 April 1896. Japanese chemist Jōkichi Takamine and his assistant Keizo Uenaka independently discovered adrenaline in 1900. In 1901, Takamine successfully isolated and purified the hormone from the adrenal glands of sheep and oxen. Adrenaline was first synthesized in the laboratory by Friedrich Stolz and Henry Drysdale Dakin, independently, in 1904.
