Abscess (abscessus), abscess, abscess - a limited cavity filled with pus, resulting from focal purulent fusion of tissues.

Etiology. The cause of abscesses is the penetration of microorganisms into tissues with damage to the skin and mucous membrane and when foreign bodies enter the tissue. They can be introduced during medical manipulations (injections, subcutaneous infusions), performed without observing aseptic rules. Often, abscesses are formed during suppuration of hematomas and lymphoextravasates, as well as as a result of the transfer of microbes by blood and lymph from a purulent focus.

Classification. Abscesses, depending on the morphological composition of purulent exudate, are divided into benign and malignant.

A benign abscess contains a thick creamy purulent exudate with a large number of live white blood cells; the infectious focus is localized by a full-fledged granulation barrier.

A malignant abscess contains liquid purulent exudate with a huge number of microbes and a small amount of live white blood cells, tends to generalize a slow-forming granulation barrier, phlegmon may develop.

According to the clinical course, abscesses are divided into hot (acute) and cold (chronic); by localization - on the superficial and deep.

Clinical signs.
Initially, there is an increase in local temperature, skin hyperemia, pain, then a characteristic swelling of a conical shape, with fluctuation on palpation. General clinical signs are well expressed in horses. They noted an increase in body temperature, increased heart rate and respiration. In cattle, hypotension of the stomach is possible. In such animal species, leukocytosis and acceleration of CO are observed.

The diagnosis is made according to clinical signs, is specified and differentiated by puncture of the swelling.

Treatment. In the initial period (in the stage of infiltration), a short novocainibiotic blockade is made. You can use alcohol-ichthyol warming compresses, oil balsamic dressings according to Vishnevsky. With the formed abscesses, purulent exudate is aspirated, after which antibiotics are introduced in a small volume on a 0.5% solution of novocaine. Cattle should be given enzymes along with antibiotics (fibrilysin, chymopsin, chymotrypsin, etc.). After 2-3 days, purulent exudate is aspirated. With a large accumulation of the abscess, after 5-6 days, the infected wound is opened and treated.

  1. Epidural Abscess
    Epidural abscess - an infectious process that develops between the bones of the skull and the outer leaf of the dura mater, may be accompanied by osteomyelitis. Due to the fact that the pathogen easily penetrates through the dura mater along the emissary veins, subdural empyema is often accompanied by an epidural abscess. Major causative agents The most common cause of
  2. Abscess
    Physical blockage An abscess is a collection of pus in one place. Distinguish between hot and cold abscesses. With a hot abscess (it occurs much more often), pus accumulates very quickly and all four signs of inflammation appear: swelling, redness, temperature and pain. A cold abscess is characterized by a slow accumulation of fluid in one place with no signs of inflammation. Emotional
    An abscess is a limited inflammation in tissues or organs, characterized by an accumulation of pus in a newly formed cavity under a dense membrane. An abscess most often occurs after any mechanical damage to the skin (for example, due to a splinter), through which pyogenic microbes (staphylococci, streptococci, Pseudomonas aeruginosa, cryptococcus fungi, etc.) penetrate the skin, causing
  4. Pharyngeal abscess
    Clinical picture Pharyngeal abscess is a purulent fusion of the lymph nodes and loose tissue of the pharyngeal space. It is especially common in debilitated children under the age of 2-3 years, rarely in adults. In childhood, usually occurs after infectious diseases, acute respiratory viral infections, measles, scarlet fever. In adults, pharyngeal abscesses
  5. Abscess of the larynx
    An abscess of the larynx may be the final stage of phlegmonous laryngitis, but more often it is caused by a body injury (fish bone, etc.). An abscess occurs mainly on the lingual surface of the epiglottis or in the region of one of the arytenoid cartilages, and usually develops gradually against the background of a general inflammatory reaction of the body. Complaints boil down to pain when swallowing. 2-3 days after injury
  6. Brain Abscess
    Clinic. An abscess of the brain is a limited abscess in the brain tissue - intracerebral, or epidural, subdural. It is caused by streptococci, staphylococci, pneumococci, etc. Contact pathogens (otogenically determined), metastatic (pneumonia, lung abscess), bronchiectatic abscesses and abscesses arising from open craniocerebral injuries are distinguished pathogenetically.
  7. Otogenic intracranial abscesses
    An extradural abscess is the accumulation of pus between the dura and the bone. It occurs as a result of the spread of the inflammatory process from the mastoid process and tympanic cavity into the cranial cavity and is localized in the middle or posterior cranial fossae. An extradural abscess is usually a complication of chronic suppurative otitis media; often observed
  8. Paratonsillar abscess (paratonsillitis)
    This disease is also called phlegmonous tonsillitis. Between the capsule of the tonsil and the pharyngeal fascia, the distance between which is normally 0.5-1 cm, is located paratonsillar tissue, and behind the pharyngeal fascia, laterally, there is fiber of the parapharyngeal space. These spaces are made of fiber, the inflammation of which, and in the final stage, and abscess formation determines the clinic
  9. Extradural abscess
    An extradural abscess usually has a contact mechanism of occurrence. The source of infection in most cases is osteoperiostitis, a carious process located in the wall of the paranasal sinus, which can occur with their chronic inflammation (frontitis, ethmoiditis, sphenoiditis). The onset of the disease is characterized by the appearance of a limited focus of inflammation in the dura mater
  10. Pelvic abscesses
    Abscesses of the pelvic cavity are a delimited accumulation of pus in the cystic-uterine or rectal-uterine space. Such abscesses can form with purulent-inflammatory saccular masses in the appendages, as well as in the postoperative period. In this case, the resulting adhesions delimit the accumulation of pus from the free parts of the abdominal cavity. In the beginning, an inflammatory
    Lung abscess is a pathological process characterized by the formation of a limited cavity in the lung tissue as a result of its necrosis and purulent fusion. The main pathogens The development of lung abscess is primarily associated with the anaerobic flora - Bacteroides spp., F.nucleatum, Peptostreptococcus spp., P.niger - often in combination with enterobacteria (due to aspiration of the contents
  12. Brain Abscess
    A brain abscess is a capsule-limited accumulation of brain detritus, white blood cells, pus, and bacteria. The main causative agents The etiological cause of brain abscess can be bacteria, fungi, protozoa and helminths. Of the bacterial pathogens, the most common are vermin streptococci (S. anginosus, S. constellatus and S. intermedius), which occur in 70% of cases. AT
  13. Pharyngeal and paratonsillar abscesses
    A pharyngeal abscess develops as a result of a purulent lesion of deep pharyngeal lymph nodes and loose fiber located in the pharyngeal space. These lymph nodes are regional for the posterior sections of the nasal cavity, paranasal sinuses, auditory tube, middle ear, nasal pharynx and palatine tonsils. A pharyngeal abscess may occur in newborns, but
