Abscess

abscess2
Abscess
  • It’s a localized infection with collection of bus in a cavity
  • Many microrganisms may be pyogenic in action and may cause abscess
  • Like staph., srept., corynebacterium pyogenes, E coli ..etc
abscess3
Abscess
  • Most of abscess begin as cellulites that become localized as an abscess form, the capillaries closed so the infection will kept localized
abscess4
Abscess
  • If the infection is highly virulent, the clots in small blood v. may destroyed
  • septic emboli may carried to other parts of the body proceeding abscesses, pyemia and septicemia
abscess5
Abscess
  • When the infection occur in the tissue the bacteria on the center of the inflammatory area destroy the T.
  • Defense become active and Leukocyte surround the infected area until local immunity is produced
abscess6
Abscess
  • The dead bacteria and many PMNc remain in the necrotic cavity and these together with cellular debris, lymph and serum produce Suppurative or formation of pus
abscess7
Abscess
  • The wall of abscess cavity consist of granulation T. that contain PMNc, leukocyte, lymphocyte, fibroblast and endothelial cells which activate the local immunity of the T.
clinical signs of the abscess9
Clinical signs of the abscess

Redness

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

Heat

  • This due to increase flow of the blood through the affected part
clinical signs of the abscess10
Clinical signs of the abscess

Swilling

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

Pain

  • Due to P. on the nerve ending of the T.
clinical signs of the abscess11
Clinical signs of the abscess
  • Some time abscess may lead to loss of function of the part of affected depending on the degree of destruction which is cause by the abscess
diagnosis
Diagnosis

Diagnosis

  • Depending on the clinical signs
  • Exploratory puncture specially in the mature abscess
slide13
D.D

D.D

  • Cyst
  • Hematoma
  • Distended synovial bursa
  • Abdominal hernia
treatment15
Treatment

In acute mature abscess

  • Hasten the maturation abscess by application of counter irritant
  • Like iodine ointment 5%
treatment16
Treatment
  • In certain cases its advisable to open the abscess as soon as its diagnose
  • Like when the abscess localized near the vital organ or in the abdominal cavity or near the joint
treatment17
Treatment

Surgical stapes

  • The skin over the abscess should be clipped and shear and antiseptic application
  • An open is made at the most dependant part of the swilling which is fluctuating and its better in the ventral part of the swilling to provide complete drainage of the abscess cavity
treatment18
Treatment
  • After the pus is removed the cavity should be checked for any F.B and necrotic T. should be removed
  • Then although flashing of the cavity should be made by suitable antiseptic like 10% povidone iodine or 1% chlor hixidene
treatment19
Treatment
  • Then the abscess cavity should be packed completely with gauze saturated with ten. Iodine 5%
  • This ten. Iodine gauze help in destruction of the lining membrane of abscess cavity and reduce the number of microrganisms
treatment20
Treatment
  • The gauze is removed in 24h and then the cavity again flashed with mild antiseptic solution
treatment21
Treatment

Treatment in cold abscess or chronic abscess

  • Its developed very slowly due to chronic trauma to a certain area and it show little or no inflammatory reaction
treatment22
Treatment
  • Sometime they gradually undergo softening and burst causing ulceration to the skin and mucous membrane
  • The causes may be has a result of infectious dis. Like strangles, glander and T.B
  • The treatment is the same line of acute abscess
treatment23
Treatment
  • Counter irritant can be applied to render the abscess to acute form and bring the pus near the surface of the skin
