Aspiration Pneumonia
Även känd som: Aspiration pneumonitis
Kort sagt
Aspiration pneumonia is a serious, life-threatening lung infection in dogs and cats caused by inhaling foreign material like food or stomach acid. Learn the symptoms, risk factors, and treatment options.
TL;DR. Allvarlig lunginfektion efter inandning av mat, kräks eller magsyra; omedelbar vård.
Främmande material passerar struphuvudet och inflammerar lungan kraftigt.
Vad är det?
Chemical pneumonitis plus often bacterial pneumonia after inhaling food, vomit, or gastric acid. Airway protection fails (GI disease, neurology, larynx, anesthesia).
Orsaker och riskfaktorer
Almost always secondary. GI disorders >60% (megaesophagus ~26% leading). Neurologic ~18%, laryngeal ~13%; often multiple factors including recent anesthesia. Periodontal disease raises bacterial load.
Tecken att bevaka
- Cough, respiratory distress, lethargy, fever, hypoxemia, crackles (common)
- Cyanosis, collapse, regurgitation, shock (occasional)
Ortopnéställning: utsträckt hals underlättar andningen.
Hur veterinärer diagnostiserar
Auscultation (may be normal), thoracic radiographs (often right middle lobe), SpO₂, arterial blood gas, tracheal wash/culture, bronchoscopy if needed.
Behandlingsalternativ
Oxygen, IV fluids. Broad-spectrum antibiotics culture-guided. Glucocorticoids only with extreme caution for pure chemical pneumonitis. Nebulization and coupage when stable.
Prognos
Favorable with early aggressive care (survival ~77–82% in referral settings); worse with ARDS/ventilation. Recurrence if cause uncontrolled.
Förebyggande
Megaesophagus: upright feeding. Pre-anesthetic fasting. Dental care. Investigate vomiting/regurgitation early.
När ringa veterinären
Grade-5 emergency: severe dyspnea, moist cough, blue mucous membranes, collapse, fever with apathy.
