Acute epiglottitis

From WikiLectures

Template:Infobox - illness Acute epiglottitis (MKN-10: Template:MKN) is a life-threatening swelling of the epiglottis and septicemia caused by Haemophilus influenzae type B. It most commonly affects children aged 1-6 years.[1]

The introduction of vaccination against Haemophilus influenzae type b into the routine calendar has virtually eliminated it.[2]

Pathogenesis[edit | edit source]

Upper airway obstruction occurs by covering part or all of the laryngeal entrance with an epiglottis magnified several times. The cause is the rapidly advancing phlegmon epiglottis. A significant predisposition to these invasive microbes is the reduced ability to produce IgG 2 (protection against invasive encapsulated bacteria), which is physiological at this age.[2]

The clinical picture[edit | edit source]

Acute epiglottitis has a rapid development (in the order of hours). It starts with a sharp sore throat and difficulty swallowing, then dyspnoea appears. The child is pale, hypoxic, sitting in a forward bend, saliva flowing from his mouth because they cannot drain through the valecules along the epiglottis. The child has a fever, a quiet voice and can cough carefully, superficially.[3]

The physical finding in the lungs is poor, the progression of obstruction, ie dysphagia and dyspnoea coming within a few hours. Rarely, paratonsillar / retropharyngeal abscess, severe pablan tonsillitis may have a similar effect.[2]

Diagnosis[edit | edit source]

Accurate diagnosis is based on a good aspect of the epiglottis. We perform a gentle aspect of the pharynx after a short pressing of the tongue with a spatula. Enlarged, reddish and soaked epiglottis, often of bizarre shape, appears. Sometimes the epiglottis is not visible, as saliva and inflammatory secretion stagnate in the area, creating a characteristic "pond". In a typical course, the diagnosis can be made on the basis of a clinical finding, independent of the aspect of the epiglottis.

The key is to be able to readily distinguish between acute epiglottitis and laryngitis :

Acute epiglottitis Acute laryngitis[1][3]
Avarage age 3–4 years 6–36 months
The course hours (6-24 hours) days (2-3)
Prodromes runny nose
Cough –/meek barking
Feeding No Yes
Mouth saliva flows out closed
Toxicity Yes No
Temperature > 38,5° C < 38,5 °C
Stridor fine creaking
Voice weak / quiet hoarse
Recurrences No Yes

Treatment[edit | edit source]

  • in pre-hospital therapy, do not traumatize the child, transport it completely at rest, sitting; [2]
  • endotracheal intubation;
  • hospitalization in the ICU;
  • blood culture collection;
  • iv ATB: 2nd or 3rd generation cephalosporins (cefuroxime, ceftriaxone, cefotaxime) 7-10 days.
  • rifampicin should be given as a precaution to persons who come into contact with the child's disability. [1]

Prevention[edit | edit source]

Regular vaccination against diphtheria, tetanus, whooping cough, hepatitis B virus, polio and Haemophilus influenzae type b (since 2007 as a hexavaccine).

Polyribosylribitol phosphate conjugated to tetanus or genetically modified diphtheria toxoid is used.
