AbscessAbscessIt’s a localized infection with It’s a localized infection with collection of bus in a cavity collection of bus in a cavity

Many microrganisms may be Many microrganisms may be pyogenic in action and may cause pyogenic in action and may cause abscessabscess

Like staph., srept., corynebacterium Like staph., srept., corynebacterium pyogenes, E coli ..etcpyogenes, E coli ..etc

AbscessAbscess

Most of abscess begin as cellulites Most of abscess begin as cellulites that become localized as an abscess that become localized as an abscess form, the capillaries closed so the form, the capillaries closed so the infection will kept localized infection will kept localized

AbscessAbscess

If the infection is highly virulent, the If the infection is highly virulent, the clots in small blood v. may destroyed clots in small blood v. may destroyed

septic emboli may carried to other septic emboli may carried to other parts of the body proceeding parts of the body proceeding abscesses, pyemia and septicemia abscesses, pyemia and septicemia

AbscessAbscess

When the infection occur in the When the infection occur in the tissue the bacteria on the center of tissue the bacteria on the center of the inflammatory area destroy the T.the inflammatory area destroy the T.

Defense become active and Defense become active and Leukocyte surround the infected area Leukocyte surround the infected area until local immunity is produced until local immunity is produced

AbscessAbscess

The dead bacteria and many PMNc The dead bacteria and many PMNc remain in the necrotic cavity and remain in the necrotic cavity and these together with cellular debris, these together with cellular debris, lymph and serum produce lymph and serum produce Suppurative or formation of pus Suppurative or formation of pus

AbscessAbscess

The wall of abscess cavity consist of The wall of abscess cavity consist of granulation T. that contain PMNc, granulation T. that contain PMNc, leukocyte, lymphocyte, fibroblast and leukocyte, lymphocyte, fibroblast and endothelial cells which activate the endothelial cells which activate the local immunity of the T. local immunity of the T.

RednessRedness

It can be determined in gray animal It can be determined in gray animal and only when the swilling is near and only when the swilling is near the surfacethe surface

HeatHeat

This due to increase flow of the blood This due to increase flow of the blood through the affected part through the affected part

Clinical signs of the abscessClinical signs of the abscess

SwillingSwilling

Always occur except in the location Always occur except in the location when the anatomy of the parts when the anatomy of the parts prevents expansion prevents expansion

PainPain

Due to P. on the nerve ending of the Due to P. on the nerve ending of the T. T.

Clinical signs of the abscessClinical signs of the abscess

Some time abscess may lead to loss Some time abscess may lead to loss of function of the part of affected of function of the part of affected depending on the degree of depending on the degree of destruction which is cause by the destruction which is cause by the abscess abscess

Depending on the clinical signs Depending on the clinical signs

Exploratory puncture specially in the Exploratory puncture specially in the mature abscess mature abscess

D.DD.DD.DD.D

Cyst Cyst

Hematoma Hematoma

Distended synovial bursaDistended synovial bursa

Abdominal hernia Abdominal hernia

TreatmentTreatment

TreatmentTreatment

In acute mature abscessIn acute mature abscess

Hasten the maturation abscess by Hasten the maturation abscess by application of counter irritantapplication of counter irritant

Like iodine ointment 5% Like iodine ointment 5%

TreatmentTreatment

In certain cases its advisable to open In certain cases its advisable to open the abscess as soon as its diagnose the abscess as soon as its diagnose

Like when the abscess localized near Like when the abscess localized near the vital organ or in the abdominal the vital organ or in the abdominal cavity or near the joint cavity or near the joint

TreatmentTreatmentSurgical stapes Surgical stapes

The skin over the abscess should be The skin over the abscess should be clipped and shear and antiseptic clipped and shear and antiseptic applicationapplication

An open is made at the most dependant An open is made at the most dependant part of the swilling which is fluctuating and part of the swilling which is fluctuating and its better in the ventral part of the swilling its better in the ventral part of the swilling to provide complete drainage of the to provide complete drainage of the abscess cavity abscess cavity

TreatmentTreatment

After the pus is removed the cavity After the pus is removed the cavity should be checked for any F.B and should be checked for any F.B and necrotic T. should be removed necrotic T. should be removed

Then although flashing of the cavity Then although flashing of the cavity should be made by SSS followed by should be made by SSS followed by suitable antiseptic like 10% povidone suitable antiseptic like 10% povidone iodine or 1% chlor hixidene iodine or 1% chlor hixidene

TreatmentTreatment

Then the abscess cavity should be Then the abscess cavity should be packed completely with gauze packed completely with gauze saturated with ten. Iodine 5% saturated with ten. Iodine 5%

This ten. Iodine gauze help in This ten. Iodine gauze help in destruction of the lining membrane destruction of the lining membrane of abscess cavity and reduce the of abscess cavity and reduce the number of microrganisms number of microrganisms

TreatmentTreatment

The gauze is removed in 48h and The gauze is removed in 48h and then the cavity again flashed with then the cavity again flashed with mild antiseptic solution mild antiseptic solution

TreatmentTreatment

Treatment in cold abscess or chronic Treatment in cold abscess or chronic abscessabscess

Its developed very slowly due to Its developed very slowly due to chronic trauma to a certain area and chronic trauma to a certain area and it show little or no inflammatory it show little or no inflammatory reaction reaction

TreatmentTreatmentSometime they gradually undergo Sometime they gradually undergo softening and burst causing ulceration to softening and burst causing ulceration to the skin and mucous membranethe skin and mucous membrane

The causes may be has a result of The causes may be has a result of infectious dis. Like strangles, glander and infectious dis. Like strangles, glander and T.BT.B

The treatment is the same line of acute The treatment is the same line of acute abscess abscess

TreatmentTreatment

Counter irritant can be applied to Counter irritant can be applied to render the abscess to acute form and render the abscess to acute form and bring the pus near the surface of the bring the pus near the surface of the skin skin
