Anaesthesia of teat Ring block

Needle placement for teat anesthesia in cattle.

(A) Inverted V block. (B) Ring block. (C)Placement of a tourniquet and teat cannula for infusion of local anesthetic into the teat cistern.Use plain Lignocaine without adrenalineTeat LacerationsTeat lacerations are categorized as Acute Chronic (more than 12 hours old). Surgical intervention on the teat is best performed during the first 12 hours following the injury. Teat lacerations are classified as simple or complex (inverted Y or U), Longitudinal or transverse, and proximal or distal. The orientation of the blood supply of the teat is longitudinal.A transverse laceration results in more damage to the blood supply resulting in more edema, avascular necrosis and dehiscence post-operatively compared with a longitudinal laceration. The more circumference is involved, the worse is the prognosis. Distal injuries involving the streak canal are also regarded as having a poor prognosis. Proximal and transverse lacerations are difficult to repair. At this location, the mucosa is difficult, the suture and the teat swell more post-operatively.Teat lacerations are classified as being partial thickness (skin to submucosa) Full thickness (skin to mucosa with milk leaking out of the incision). recommended to apply cold hydrotherapy on the injured teat while waiting for the veterinarian. The hydrotherapy helps decrease the inflammation and helps clean the teat for surgery.You need 10 or 15 No. Blade- for debridement

Laceration repair

Mucosa and the submucosa are first reconstructed using a simple continuous pattern. The muscular and subcutaneous layers are closed with a simple continuous patternThe skin is carefully apposed using a simple interrupted. Care is taken to leave the skin sutures slightly loose because swelling is expected at the surgery site.Throughout the procedure, the surgery site is frequently lavaged with saline. Antibiotics can be added to the lavage solution.Hemostasis is performed to avoid formation of mural hematoma that may obstruct the teat cistern.Post operativeself-retaining plastic teat canula with a cap into the streak canal Antibiotic umbrella.Severe post-operative edema can be treated by applying ice around the teat for a few days.Crushed ice in a rectal sleeve can be placed around the teat. Daily Twenty minute application.The skin sutures are removed no more then 9 days after the surgery. If the sutures are left in place longer, excessive fibrosis and suture tract infection may occur.

To enlarge tight streak canals

What instrument is thisSpiral teat curette

NTI natural teat inserts.

Obstruction where a mass of granulation tissue or stenosis waspresent but affected less than 30% of the mucosal surface of the teat cistern. The mucosa proximal or distal to the lesion is grossly normal.

Type 1: Obstruction where greater than 30% of the teat cistern mucosa was abnormal due to stenosis or proliferating granulation tissue. Mucosa proximal to the lesion was grossly normal. Teat canal is normal in appearance.

Type II

Obstruction due to presence of a membranous or fibrous structure between gland and teat cistern or between lactiferous duct and gland cistern. The mucosa of the teat cistern is normal.Type IIIObstruction due to fibrosis and stenosis of an extensive portion of the teat and gland cisterns (>30%).The mucosa is abnormal in the constricted area.

Type IV: Abnormalities where a teat fistula, a webbed teat, or a laceration leading to a fistula was present. The mucosa of the teat or gland cistern is inflamed or normal.

Type V: What does chemical destruction of the teat involve100 cc of (10% formalin diluted in 500 cc of saline)Or 100 cc of 3% silver nitrate solution250 ml of acriflavine (1ml in 500 ml of NSS)20 ml of 5% Copper sulfate60 ml of chlorhexidinePre-treat with Megludyne
