Epiglottitis is inflammation of the epiglottis - the flap that sits at the base of the tongue, which keeps food from going into the trachea (windpipe). Due to its place in the airway, swelling of this structure can interfere with breathing and constitutes a medical emergency. The infection can cause the epiglottis to either obstruct or completely close off the windpipe.
Cause
Epiglottitis involves bacterial infection of the epiglottis, most often caused by Haemophilus influenzae type B, although some cases are attributable to Streptococcus pneumoniae or Streptococcus pyogenes.
Symptoms
Epiglottitis typically affects children, and is associated with fever, difficulty swallowing, drooling, and stridor. It is important to note however that since the introduction of the Hemophilus Infuenzae vaccination in many Western countries (including th UK), the disease is becoming relatively more common in adults. The child often appears acutely ill, anxious, and has very quiet shallow breathing with the head held forward, insisting on sitting up in bed. The early symptoms are insidious but rapidly progressive, and swelling of the throat may lead to cyanosis and asphyxiation. Cases in adults are most typically seen amongst abusers of crack cocaine and have a more subacute presentation.
Diagnosis
Diagnosis is confirmed by direct inspection using laryngoscopy, although this may provoke airway spasm. The epiglottis and arytenoids are cherry-red and swollen. The most likely differential diagnostic candidates are croup, peritonsillar abscess, and retropharyngeal abscess.
On lateral C-spine X-ray, the thumbprint sign is a finding that suggests the diagnosis of epiglottitis.[1]
Treatment
Epiglottitis requires urgent endotracheal intubation to protect the airway. Ideally, this should be performed by an experienced anesthesiologist or respiratory therapist, with otolaryngology back-up in case of failed intubation. If intubation fails, tracheotomy is required.
In addition, patients should be given an antibiotic drug such as ceftriaxone or chloramphenicol either alone or in association with penicillin or ampicillin for streptococcal coverage.
Complications
Some patients may develop pneumonia, lymphadenopathy or septic arthritis.
