Aspiration Pneumonia
Também conhecido como: Aspiration pneumonitis
Em resumo
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. Infecção pulmonar grave por inalação de comida, vômito ou ácido gástrico; atendimento imediato.
O material estranho ultrapassa a laringe e inflama o pulmão.
O que é?
Chemical pneumonitis plus often bacterial pneumonia after inhaling food, vomit, or gastric acid. Airway protection fails (GI disease, neurology, larynx, anesthesia).
Causas e fatores de risco
Almost always secondary. GI disorders >60% (megaesophagus ~26% leading). Neurologic ~18%, laryngeal ~13%; often multiple factors including recent anesthesia. Periodontal disease raises bacterial load.
Sinais a observar
- Cough, respiratory distress, lethargy, fever, hypoxemia, crackles (common)
- Cyanosis, collapse, regurgitation, shock (occasional)
Postura ortopneica: pescoço estendido para facilitar a respiração.
Como os veterinários diagnosticam
Auscultation (may be normal), thoracic radiographs (often right middle lobe), SpO₂, arterial blood gas, tracheal wash/culture, bronchoscopy if needed.
Opções de tratamento
Oxygen, IV fluids. Broad-spectrum antibiotics culture-guided. Glucocorticoids only with extreme caution for pure chemical pneumonitis. Nebulization and coupage when stable.
Prognóstico
Favorable with early aggressive care (survival ~77–82% in referral settings); worse with ARDS/ventilation. Recurrence if cause uncontrolled.
Prevenção
Megaesophagus: upright feeding. Pre-anesthetic fasting. Dental care. Investigate vomiting/regurgitation early.
Quando chamar o veterinário
Grade-5 emergency: severe dyspnea, moist cough, blue mucous membranes, collapse, fever with apathy.
