Acute epiglottitis is an acute inflammatory condition of the epiglottis and nearby structures like the arytenoids, aryepiglottic folds, and vallecula.It is a life-threatening infection that causes profound swelling of the upper airways which can lead to asphyxia and respiratory arrest.Bacterial etiology is the most common cause of epiglottitis. Soft tissue lateral xray of neck shows thumb sign. Airway management is the main concern of epiglottitis.
This is a seminar presentation conducted by 4th year medical students under supervision of a lecturer. Reference were not attached here, but all information are from google, few textbooks and also from previous ENT posting's seminar.

27. Rapid overview : Epiglottitis ( supraglottitis ) in children Secure airway before diagnostic evaluation if respiratory distress is severe. Communicate early with otolaryngologist, anesthesiologist, and intensivist. Keep the patient in a setting where the airway can be rapidly managed if necessary ( eg, the emergency department, operating room, or intensive care unit) Evaluation Febrile, toxic - appearing children with rapid onset and progression of dysphagia, drooling, and respiratory distress Consider epiglottitis in : Respiratory distress : stridor, tachypnea, anxiety, refusal to lie down, " sniffing " or " tripod " posture . Sore throat, dysphagia, drooling, anterior neck pain ( at the level of the hyoid). Muffled " hot potato " voice Marked retractions and labored breathing indicate impending respiratory failure . Signs and symptoms that may indicate epiglottitis
28. Stridor, drooling, suprasternal and subcostal retractions Swollen, erythematous epiglottis, inflammation of the supraglottic structures Look for signs of extra-epiglottic infection (eg, pneumonia) Findings: Defer examination of the pharynx in children with signs of moderate/severe respiratory distress Examine the patient in the upright position Attempt to visualize the epiglottis (with aid of tongue depressor, direct or indirect laryngoscopy) only in patients with mild distress and not in those with more severe distress Maintain the child in a position of comfort with parent present Avoid invasive procedures Examination :
29. If abrupt obstruction: Attempt bag-valve mask ventilation first During laryngoscopy, pressure on the chest by an assistant may produce bubbling and help indicate the location of the glottis Perform needle cricothyrotomy (<8 years of age) or surgical cricothyrotomy (>8 years of age) if unable to ventilate or intubate Secure the airway, if time allows, in the operating room by anesthesia or otolaryngologist (artificially or surgically if necessary) Airway Management : Enlarged epiglottis ("thumb" sign), loss of vallecular air space, thickened aryepiglottic folds, distended hypopharynx, loss of cervical lordosis Findings : Soft-tissue radiograph of the lateral neck (portable if possible) when the clinical diagnosis is in doubt Defer imaging in patients with severe respiratory distress or in whom it will delay definitive visualization of the epiglottis Imaging :
