Abscess

Introduction to abscess Abscess is a localized pus accumulation in tissues, organs or body cavity due to necrosis and liquefaction of the diseased tissue during acute infection. There is a complete pus wall around it. The common pathogen is Staphylococcus aureus. The abscess can be caused by an acute suppurative infection, or by a pathogen of a distant source of infection through the bloodstream or lymphatic vessels. It is often caused by necrosis and dissolution of inflammatory tissue under the action of toxins or enzymes produced by bacteria, forming a abscess cavity, exudate in the cavity, necrotic tissue, pus cells and bacteria to form a pus. Because fibrin in the pus forms a reticular scaffold, the lesion is restricted to the local area, and the other part of the abscess is filled with edema and leukocyte infiltration. The resulting granulation tissue proliferates mainly in the wall of the abscess. Abscesses may have different clinical manifestations due to their different locations. The disease can often be diagnosed by understanding the medical history, clinical examination and necessary auxiliary examination. Treatment is mainly based on drainage. basic knowledge The proportion of illness: 0.03% Susceptible people: no special people. Mode of infection: non-infectious Complications: sepsis

Abscess cause

Staphylococcus aureus is invaded into tissues or blood vessels. The abscess is mainly caused by Staphylococcus aureus. The plasma coagulase produced by the bacteria converts the exuded fibrinogen into cellulose, preventing the spread of pathogenic bacteria. Staphylococcus aureus also has a laminin receptor, which can form migratory abscesses at a distance through the vessel wall.

In early abscesses, bacteria produce toxins that cause local tissue necrosis, followed by extensive neutrophil infiltration and disintegration to explain proteolytic enzymes that liquefy necrotic tissue and form a abscess. After a period of time, granulation tissue hyperplasia can occur around the abscess and surround the abscess to form a so-called "abstoma", which has the effect of absorbing pus and limiting the spread of inflammation.

Abscess prevention

The disease is mainly caused by bacterial infection, causing necrosis of inflammation tissue, forming a abscess cavity. The key to this disease is: prevention, second detection, early diagnosis, timely treatment, which can often prevent the disease from worsening, otherwise it may lead to sepsis. Septicemia is life-threatening.

Abscess complications Complications sepsis

May cause sepsis, sepsis and life-threatening.

Abscess symptoms Common symptoms Laryngeal obstruction fatigue Parino eye-adenochrome syndrome Systemic infection Symptoms Nasal root edema abscess Hand acute suppurative infection

1. Superficial abscess is slightly higher than the body surface, red, swollen, hot, painful and fluctuating. Small abscess, deep position, thick wall, the sense of fluctuation is not obvious.

2. Deep abscess generally does not have a sense of fluctuation, but the surface of the abscess often has edema and obvious local tenderness, accompanied by symptoms of systemic poisoning.

Abscess examination

(1) may have a history of acute suppurative infection.

(2) Local redness and pain and a sense of fluctuating, try to have pus.

(3) Systemic symptoms include fever, fatigue, etc.

(4) The white blood cell count is increased.

(5) Deep abscess can be in liquid dark area after B-ultrasound examination.

Diagnosis of abscess

Diagnose based on:

1. Shallow: The abscess manifests as local redness, swelling, heat, pain and tenderness, and then fluctuates.

2. Deep: The abscess is a local diffuse swelling, pain and tenderness, and the fluctuation is not obvious. The puncture can be taken out by the test puncture, and it can also be used as an ultrasound consultation.
