Study Notes
Epiglottitis
- Historically a childhood disease, now increasingly observed in adults due to factors like vaccination and decreased childhood incidence.
- Etiological agents include Staphylococcus, Streptococcus, and Haemophilus influenzae.
- Diagnosis confirmed through lateral neck x-ray displaying "thumbprint" sign; clinical diagnosis considers signs such as stridor, dysphagia, and drooling.
- Characteristic patient appearance includes protruding chin (like "smelling flowers").
- Treatment focus includes airway management, corticosteroids, nebulized vasoconstrictor (often racemic epinephrine), and intravenous antibiotics (third-generation cephalosporins) alongside humidified oxygen.
Pleural Effusion
- Defined as fluid accumulation between visceral and parietal pleura.
- Diagnosis primarily through chest X-ray assessment.
- Management involves treating the underlying cause; therapeutic thoracentesis indicated if symptomatic at rest.
- Fluid samples sent for cytology to assist in determining cause.
- In cases of massive or severe effusion, tube thoracostomy recommended.
- Light's criteria used to evaluate and classify the effusion.
Pneumothorax (PTX)
- Can be classified as spontaneous or traumatic in origin.
- Management options vary from conservative approaches to tube thoracostomy based on severity.
- Caution against mechanical ventilation without prior tube thoracostomy, as it may lead to tension pneumothorax.
- Conservative treatment preferred for very small pneumothorax, considering factors such as acute onset and diffuse involvement, with severe hypoxia being a critical indicator.
- Common causes include pneumonia, sepsis, and aspiration phenomena.
Epiglottitis
- Historically a pediatric condition, now increasingly observed in adults due to vaccination and other factors.
- Common pathogens include Staphylococcus, Streptococcus, and Haemophilus influenzae.
- Diagnosis typically involves a lateral neck X-ray, often revealing a "thumbprint" sign.
- Clinical signs include stridor, dysphagia, drooling, and a characteristic posture with the chin extended (resembling smelling flowers).
- Treatment focuses on airway management, corticosteroids, nebulized vasoconstrictors (usually racemic epinephrine), antibiotics (typically third-generation cephalosporins), and humidified oxygen.
Pleural Effusion
- Defined as the accumulation of fluid between the visceral and parietal pleura of the lungs.
- Diagnosis primarily achieved through a chest X-ray.
- Management involves addressing the underlying cause of the effusion.
- If patient is symptomatic at rest, therapeutic thoracentesis is indicated, with fluid sent for cytology to aid in diagnosis.
- Tube thoracostomy required for massive or severe cases.
- Light's criteria helps differentiate between transudative and exudative pleural effusions.
Pneumothorax (PTX)
- Can occur spontaneously or due to trauma.
- Management can be conservative for small PTX; larger cases may require tube thoracostomy.
- Mechanical ventilation should be avoided unless tube thoracostomy is in place to prevent tension physiology.
- Common causes include pneumonia, sepsis, and aspiration, often leading to acute onset and severe hypoxia.
