It is the open injury of soft tissue caused by external force, such as scrape, stab, cut, laceration, bite and wound caused by operation. If there is a large number of bacteria in the process of trauma, it can occur infection, suppurative inflammation. The necrobacillosis (foot rot) of sheep was caused by the suppuration of the infected hoof, and the tetanus of sheep was caused by castration or improper disinfection of the wound in handling the umbilical cord of lamb, caused by a toxin produced by the invasion of a pathogen. Trauma can also be a cause of abortion in sheep.
Symptoms: the main symptoms of a variety of trauma is bleeding, pain and wound dehiscence, severe trauma, often occur in varying degrees of systemic symptoms. Wound such as infection suppuration, wound margin and wound swelling, pain, local temperature increases, the wound constantly discharge pus or the formation of a very thick abscess scab. When the wound cavity is deep and the wound is small or foreign body is present in the wound, sometimes an abscess or cellulitis of the surrounding tissue (acute progressive suppurative inflammation of the subcutaneous, subsarcolemmal, and intermuscular Loose connective tissue) may occur with an increase in body temperature. With the resolution of suppurative inflammation, granulation tissue appeared in the wound, generally a red, flat granular, hard texture, with a sticky surface with gray-white purulent material.
How to treat: 1, the treatment of general trauma
1, wound bleeding, such as bleeding wound, can be applied pressure, clamp or ligation bleeding. Hemostatic agents can also be used, such as external use of hemostatic powder to spread the wound, if necessary, systemic hemostatic agents such as amoxicillin (2 ~ 4 mg intramuscularly, 2 ~ 3 times a day) and Vitamin K 3(30 ~ 50 mg intramuscularly, 2 ~ 3 times a day) can be used.
2. To clean the wound, cover the wound with sterilized gauze, cut off the surrounding hair, wash the wound with 0.1% bromogeramine solution or normal saline, then disinfect the wound with 5% iodine tincture.
3. Clean the wound cavity to remove the covering matter, remove the foreign body in the wound carefully with tweezers, wash the wound cavity repeatedly with normal saline, then gently absorb and dip the remaining medicine liquid and dirt in the wound with sterilized gauze, and then apply iodine tincture to the wound surface.
4. When the wound is closed and bandaged neatly, and the surgical treatment is complete, the wound can be closed; when there is danger of infection, the wound can be closed partially; when the wound is too wide, the wound can be closed at both ends; when the tissue damage is serious or inconvenient to close, the wound can be closed partly, open therapy is feasible. Lower limbs of the trauma, the general line should be bandaged. If the tissue damage or serious pollution, should be timely injection of tetanus toxoid, antibiotics.
The treatment of suppurative wound is to clean the wound, to irrigate the wound cavity with 0.1% potassium permanganate solution, 3% hydrogen peroxide or 0.1% bromogeramine solution, to enlarge the wound, open wound margin, remove deep foreign body, remove necrotic tissue, discharge pus, and finally with 10% sulfa emulsion or iodoform glycerol wound coating or gauze strip drainage. Have systemic symptoms, can be used anti-bacterial anti-inflammatory drugs, and pay attention to cardiac detoxification. For abscesses, warm therapy (such as hot compress) or application of compound lead acetate powder (Adderall) prepared with vinegar may be used at the beginning of the illness, while systemic treatment with antibiotics or sulfonamide may be used. If the above methods can not make inflammation dissipated, can be used with a weak irritant ointment coating affected areas, such as fish, such as lipid ointment, to promote the maturation of abscess. The abscess should be incised in time and the PUS should be completely removed. Rinse with 3% hydrogen peroxide or 0.1% potassium permanganate water and apply sulfa emulsion or iodoform glycerin, or as appropriate with gauze strip drainage, in order to accelerate the purification of necrotic tissue.
2. The steps of granulation wound treatment are: first clean the wound, then clean the wound surface (gently clean with normal saline) , finally, the local application of drugs (application of small irritation, can promote granulation tissue and epithelial growth of drugs, such as 3% gentian violet, etc.) . If granulation tissue vegetation, can be used copper sulfate corrosion.
