empyema

empyema

(ĕmpē-ē`mə), persistent purulent discharge into a cavity such as the pleural space or the gallbladder. Empyema results as a complication of bacterial infections such as pneumonia and lung abscess. It is now relatively rare because of the widespread availability of therapy for the infections that precipitate the disease.

Empyema

 

the accumulation of pus in a closed body cavity or in a hollow organ if the outlet for the pus is blocked by a concrement or inflammatory infiltrate. Empyema may develop after purulent inflammation of the walls of a cavity or organ caused by shifting of the inflammatory process from the nearest organ, for example, from bone to the walls of a joint cavity in osteomyelitis. It also occurs after direct penetration of the infection into a cavity upon injury to its wall, for example, after rupture of a pulmonary abscess into the pleural cavity. The symptoms of empyema vary depending on whether the condition is acute or chronic and on the site of the infection. They may include a high fever, intoxication, pain, and change in the blood composition.

Treatment may require removal of the affected organ, for example, in suppurative appendicitis and suppurative cholecystitis. In some cases the purulent cavity is opened, pus is removed and the cavity is drained, for example, in suppurative pleurisy (thoracic empyema) or suppurative arthritis.

empyema

Purulent material from the guttural pouch defines some degree of guttural pouch empyema. Guttural pouch empyema can be a primary infection, or secondary to ruptured lymph nodes into the pouch (possibly secondary to Streptococcus equi).
Complications were categorized as insertional (for example, lung or other organ laceration or perforation, hemorrhage), positional (for example, extrathoracic placement, persistent hemothoraces, or pneumothoraces), or infective (for example, minor wound infection and empyema thoracic).
[1,34,35] Drainage is the mainstay of initial treatment of complex parapneumonic effusions and empyema. Classically, this has been performed using a large-bore surgical chest drain, however as with other pathology, small-bore Seldinger drains have dramatically increased in use due to their ease of insertion and patient comfort.
Empyema was suspected, and the patient was treated accordingly, with chest tube drainage and intravenous broad-spectrum antibiotics.
