Endometritis is an inflammation of the uterine mucosa caused by bacterial infection, which can cause infertility in sick animals.

【Basic information】

Family: Reproductive system diseases

Symptoms: Increased body temperature, loss of appetite or loss of appetite, depression, hard work

【Cause】

In cases of lax disinfection and brutal midwifery during childbirth or dystocia, detachment and retained stillbirth, incomplete postpartum uterine involution, unclean mating, excessive mating, persistent estrus, and reduced body resistance to disease, diplococci, staphylococci, streptococci, Escherichia coli and other pathogenic bacteria invade the uterus and cause endometritis. Infectious diseases such as brucellosis and paratyphoid are often complicated by this disease.

【Main Symptoms】

1. Acute endometritis: The sick dog has elevated body temperature, loss of appetite or paralysis, depression, difficulty urinating, and mucus or mucopurulent exudate from the vagina. If the inflammation invades the myometrium and blood vessels of the uterus, it can cause a large amount of fibrinogen to leak out, causing necrosis of the mucosa and muscle layer, and a foul-smelling red or brown mucus exudate containing dirty white mucous membranes to flow out from the vagina. fragments. The areas around the vulva and tail are exuded, adhered, dry and clogged. The sick dog has abdominal pain. When peritonitis develops, the pain worsens and the abdomen refuses to be touched. The uterine horns can become thickened and relaxed.

2. Chronic endometritis: It usually changes from acute to acute. The systemic symptoms are often not obvious, and sometimes the body temperature rises. Vaginal examination showed that the cervix was slightly dilated. Transparent, turbid, or purulent floc exudates from the vagina for a long time. The sexual cycle rate is irregular, it is difficult to conceive, and miscarriage and stillbirth are prone to occur even if pregnancy occurs. Often secondary to pyometra.

【Diagnostic criteria】

Diagnosis requires culture of the uterine cavity contents, usually taken during laparotomy or endometrial biopsy.

【Treatment method】

Mainly to control inflammation and promote the excretion of inflammatory secretions in the uterus.

1. Uterine flushing: Use 0.1%-0.2% potassium permanganate solution to flush the uterus once a day or every other day until clear fluid is discharged. In order to reduce the absorption of exudates, 5% to 10% hypertonic saline can also be used to flush the uterus once a day. The concentration is gradually reduced to 1%, and the dosage is also gradually reduced. After flushing, inject Fuyangeng solution into the vagina and uterus.

2. Promote the discharge of exudates: First, intramuscularly inject diethylstilbestrol, 0.5 mg each time, once a day, for 2-3 days to open the cervix. Then use strong uterine contraction drugs to promote the discharge of exudates: intramuscular injection of oxytocin, 10 units each time, once a day, for 3 days.

3. Systemic therapy: intramuscular or intravenous infusion of 800,000 units of penicillin and 800,000-1 million units of streptomycin each time, daily2 times; intramuscular injection of ampicillin, 0.5 g each time, 2 times a day; intramuscular injection of neomycin sulfate, 0.5 g each time, 2 times a day. If the abdominal pain is severe, peritonitis may be secondary, and antibiotics can be given intraperitoneally.

4. Supportive therapy: For dogs with loss of appetite, intravenous infusion of 5% glucose saline, 250 ml each time, 2 times a day; feed Xiao Shi Er Kang, 1 capsule each time, once a day to supplement Essential nutrients for the body.

5. Surgical therapy: For dogs that are ineffective in long-term treatment, total hysterectomy and oophorectomy can be performed.

6. Other treatments: For dogs suspected of latent endometritis, flush the uterus with normal saline 2 hours before mating, inject 800,000 units of penicillin and 1 million units of streptomycin into the uterus 20 minutes before mating, and after mating, Injecting 80 units of penicillin and 1 million units of streptomycin into the uterus again within 24 hours can increase the pregnancy rate.

【Prevention and treatment methods】

Do a good job in sanitation and disinfection during breeding, labor and postpartum; strengthen feeding and management to prevent the occurrence of infectious diseases; dogs must be treated in time when they have persistent estrus, retained placenta, vaginitis and other diseases.
