Abscess (abscessus), abscess, abscess - a limited cavity filled with pus, formed as a result of focal purulent fusion of tissues.
Etiology. The cause of abscesses is the penetration of microorganisms into the tissue when the skin and mucous membrane is damaged and when foreign bodies get into the tissues. They can be made with medical manipulations (injections, subcutaneous infusions), produced without observing the rules of asepsis. Often, abscesses are formed during suppuration of hematomas and lymphoextrazasates, as well as as a result of the transfer of microbes by blood and lymph from the 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 living white blood cells; the infectious focus is localized by a complete granulation barrier.
Malignant abscess contains liquid purulent exudate with a huge number of microbes and a small number of living leukocytes, tends to generalize the slow-forming granulation barrier, possibly the development of phlegmon.
According to the clinical course, abscesses are divided into hot (acute) and cold (chronic); localization - on the surface and deep.
Initially, there is an increase in local temperature, skin hyperemia, pain, then a characteristic cone-shaped swelling, fluctuation on palpation. Common clinical signs are well pronounced in horses. They have an increase in body temperature, increased heart rate and respiration. In cattle, hypotonia of the foreglobe is possible. In such species of animals, leukocytosis and acceleration of CO are observed.
The diagnosis is made on the basis of clinical signs, swelling puncture is refined and differentiated.
Treatment. In the initial period (at the stage of infiltration), a short Novocinantibiotic 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 administered in a small amount with a 0.5% Novocain solution. Cattle should be administered with antibiotics enzymes (fibrilysin, himopsin, himotrypsin, etc.). After 2–3 days, purulent exudate is aspirated. With a large accumulation of his abscess after 5-6 days, the infected wound is opened and treated.

- EPIDURAL ABSCESS
Epidural abscess - an infectious process that develops between the bones of the skull and the outer sheet 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, the epidural abscess is often accompanied by a subdural empyema. The main pathogens most common cause of
Physical blockage An abscess is a collection of pus in one place. There are hot and cold abscesses. With a hot abscess (it is much more common), the pus accumulates very quickly and all four signs of inflammation appear: swelling, redness, fever and pain. A cold abscess is characterized by a slow accumulation of fluid in one place without signs of inflammation. Emotional
An abscess is a limited inflammation in the tissues or organs, characterized by the accumulation of pus in the newly formed cavity under the dense membrane. An abscess occurs most often after any mechanical damage to the skin (for example, due to a splinter), through which pyogenic microbes penetrate under the skin (staphylococci, streptococci, blue pus, fungus cryptococci, etc.), causing
- Zagothy abscess
Clinical picture. The pharyngeal abscess is a purulent fusion of the lymph nodes and loose tissue of the swallowed space. Particularly common in debilitated children under the age of 2-3 years, rarely in adults. In childhood, it usually occurs after infectious diseases, acute respiratory viral infections, measles, scarlet fever. In adults, pharyngeal abscesses.
- Laryngeal abscess
Laryngeal abscess may be the final stage of phlegmonous laryngitis, but more often it is caused by trauma to the body (fish bone, etc.). An abscess occurs predominantly on the lingual surface of the epiglottis or in the region of one of the cuspid cartilages, usually developing gradually against the background of the general inflammatory response of the body. Complaints come down to pain when swallowing. 2-3 days after injury
- ABSCESS OF THE BRAIN
Clinic. Brain abscess - a limited abscess in the brain tissue - intracerebral, or epidural, subdural. It is called streptococci, staphylococci, pneumococci, etc. Pathogenetically, contact (otogenic), metastatic (pneumonia, lung abscess), bronchiectasis abscesses and abscesses that occur during open cranial brain injuries,
- Otogenic intracranial abscesses
Extradural abscess is called the accumulation of pus between the dura mater and bone. It occurs as a result of the spread of the inflammatory process from the mastoid process and the tympanic cavity into the cranial cavity and is localized in the middle or in the posterior cranial fossa. Extradural abscess is usually a complication of chronic suppurative otitis media; often observed in this case
- Paratonsillary abscess (paratonsillitis)
This disease is also called phlegmonous sore throat. Paratonsillar fiber is located between the tonsil capsule and pharyngeal fascia, the distance between which is normally 0.5-1 cm, and parapharyngeal cellulose behind the pharyngeal fascia, lateral. These spaces are made of fiber, the inflammation of which, and in the final stage, and abscess formation determines the clinic.
- Extradural abscess
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 during their chronic inflammation (frontal, ethmoiditis, sphenoiditis). The onset of the disease is characterized by the occurrence of a limited focus of inflammation in the region of the solid brain
- Pelvic abscess
Pelvic abscess is a congested accumulation of pus in the vesicular-uterine or rectus-uterine space. Such abscesses can form during inflammatory saccular masses in the appendages, as well as in the postoperative period. At the same time, the resulting adhesions delimit the accumulation of pus from the free sections of the abdominal cavity. Initially formed inflammatory
- LUNG ABSCESS
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. Main pathogens The development of lung abscess is associated primarily with anaerobic flora - Bacteroides spp., F. nucleatum, Peptostreptococcus spp., P. niger - often in combination with enterobacteria (due to aspiration of the contents
- ABSCESS OF THE BRAIN
Brain abscess - a cluster of brain debris, leukocytes, pus and bacteria, limited by the capsule. The main pathogens Etiological cause of brain abscess can be bacteria, fungi, protozoa and helminths. Of the bacterial pathogens, the most common are green streptococci (S.anginosus, S.constellatus and S.intermedius), which are found in 70% of cases. AT
- Zakoplotny and paratonzillary abscesses
Zakrutochny abscess develops as a result of purulent lesions of deep pharyngeal lymph nodes and loose tissue located in the pharyngeal space. These lymph nodes are regional for the posterior nasal cavity, the paranasal sinuses, the auditory tube, the middle ear, the nasal pharynx, and the tonsils. A zaplottic abscess may be observed in newborns, but
