6. What is Abscess ? An abscess is a circumscribed area of inflammation or an abnormal cavity that contains pus if matured.

7. Suppration The process of formation of pus is called suppration Suppration is caused by bacteria like Staphylococcus,Streptococcus,Pseudomonas,E.coli etc. Irritants like turpentine,calomel,corton oil also cause suppration

8. ETIOLOGY OF ABSCESS The main cause of abscess are pyogenic bacteria such as_ -Sterptococcus spp -Staphylococcus spp -Pseudomonas aeruginosa -Actinomyces bovis -Actinobacillus lignieresi Foreign bodies escaping from reticulum to rib cage.

9. CLASSIFICATION OF ABSCESS 1.Acute or hot abscess 2.Chronic or cold abscess 3.Superficial abscess 4.Deep abscess 5.Embolic abscess 6.Pyaemic or metastatic abscess.

10. PATHOGENISIS A ny breach in skin and mucous membrane ↓ Pyogenic bacterial invasion ↓ Formation of pyogenic membrane ↓ Body immunity fails to fight ↓ Finally abscess develops

11. Symptoms of Abscess In superficial Abscess The appearance of localised,painful and inflammatory swelling Febrile disturbances are usually absent in superficial abscess

12. TERMINATION OF ABSCESS The normal consequences of abscess are- Pointing or maturating Rupture Draining

13. Differential Diagnosis Abscess should be differentiated from Cyst Haematoms A synovial distention An abdominal hernia Tumor Granuloma Inflamed Bursa

14. Treatment of Abscess A .Measures to hasten maturation: -Hot fomentation -Fomentation with boric sulfate,magnesium sulphate. -Blister.eg.Bin iodide of mercury .

15. Treatment of Abscess B .Pre operative consideration. -Control of animal -Clipping,shaving of the operation site -Washing with antiseptics such as Tr of iodine, povidone iodine

16. Treatment of Abscess For Large animal -LA: 2%Lidocaine HCl -Sedative: Xylazine HCl For small animal -GA: Thiopental

17. Treatment of Abscess C .Opening of Abscess: -Abscess is opened with scalpel -Insert an artery forceps into the abscess cavity. -A blunt dissection is done without damaging blood vessels and nerved. -Pierce the secondary pocket. -Wash with saline and antiseptics -Introduce even folded gauze soaked with Tr.iodine.

18. Management of Abscess Renew gauze in every alternate day. -Suture is prohibited -Size of gauze to be reduced according to the size of cavity. -Vitamin supplement is contraindicated.

19. Management of Abscess Prescription on Abscess for 100 kg BWT Rx 1.inj . S treptopen vet---------2.5gm vial × 7 Sig . inject one vial IM daily for seven days 2.inj . Hista vet--------10gm vial × 2 S ig. inject 5 ml IM once daily for fou r days.
