This Concept Map, created with IHMC CmapTools, has information related to: SX of Teat and Udders, *Ketamine Stun Standing sedation involves Ketamine 0.04mg/kg, TEAT SURGERY INSTRUMENTS* careful manipulation of tissues Brown-Adson Thumb Forceps*, *Epinepherine can cause necrosis in extermities Do not ever use Lidocaine + Epinephrine combo, TEAT SURGERY INSTRUMENTS* non-crushing clamp Doyen's Forceps*, *Repair of Teat Lacerations requires Surgery, TEAT SURGERY INSTRUMENTS* immobilize teat orifice Dr. Larson's Teat Tube*, Surgery then down to business Laceration Sx Procedure, Introduction why to do surgery General Prinicples of Teat Sx • Do not damage the teat spincter • Mastitis common • Streak canal & teat orifice tend to constrict after injury making the cow a “hardmilker” • Mucosa of teat sinus very susceptible to scarring • Teat sphincters will not regrow • Vertical teat lesions heal better than horizontal • Avoid indwelling cannulas --> leads to mastitis, One Hand Tie (Square Knot) step 2-3, Surgery always remember *Postoperative Management, Xylazine 0.02 mg/kg and butorphenol- 0.01mg/Kg in case of emergency Tolazine Reversal 2-4 times the dose of Xylazine, Lidocaine 2% the dose calcuated Dose = 0.2mg/kg Toxic dose (10mg/kg)= (10xW)/20 = XmL withdrawl time - milk 96hrs, meat 7 days, Restraint what drugs are used during the procedures Combikel LA 40, TEAT SURGERY INSTRUMENTS* trims necrotic tissue Metzenbaum Scissors*, *Lateral Susenpsory Ligament where the milk comes out *The Teat Canal, ???? **Ring Block -Ensuring that the cow is properly restrained, the teat and teat base is thoroughly cleansed. -Place an elastic band around the base of the teat if desired, to prevent diffusion of the local anaesthetic into the udder. Should not be placed if a supernumerary teat is being removed -A 2.5cm 25G needle is inserted inot the skin and muscularis layer of the teat, transverse to the direction of the teat and dorsal to the area where the analgesia is required. -Inject the local anaesthetic (lidocaine) in a ring pattern around the teat. -A total volume of 4-6mLs of 2% lidocaine should be sufficient -Following injection, massage he solution into the tissue Analgesia develops distal to the tourniquet in approximatey 10 mintues and lasts for about 2 hours, Introduction why to do surgery Teat surgery is an important part of dairy practice. Cattle should be well restrained and under appropriate anesthesia for teat surgery. In general, teat surgery is much more complicated and takes more concentration than other types of bovine surgical procedures. Flow chart shows what is common = Damage to the teat spincter and traumatic lesions., Introduction what is it? Udder of a cow. An udder is an organ formed of the mammary glands of female four legged mammals, particularly ruminants such as cattle, goats, sheep and deer. The udder is a single mass hanging beneath the animal, consisting of pairs of mammary glands., TEAT SURGERY INSTRUMENTS* lateral cuts in teat canal Lichty's Teat Knife*, TEAT SURGERY INSTRUMENTS* slitting Teat bistoury*
