Cat pyometra syndrome, in the usual proportion of cases is not large, the main reason I think the domestic cat's sterilization rate is higher. The dog is different, the owner carried out a conscious relatively small number of sterilization. Therefore, pyometra cases occur relatively more to middle aged and old cats. Strictly speaking, the cat pyometra is not rigorous, because the uterus is not necessarily accumulate pus, and sometimes can be seen in operation when the accumulation of the womb is the clearest transparent liquid. Sometimes, the accumulation of pus. In foreign textbooks on this disease is so defined: Cystic endometrial hyperplasia - pyometra syndrome (Cystic endometrial hyperplasia-pyometra complex). Pyometra can be life-threatening to the cat.
If ovarian function is abnormal, excessive progesterone (progesterone) will be secreted, which can stimulate the growth of endometrial glands and secretion, can also lead to accumulation of fluid in the uterine cavity, while the uterine cavity increases. At the same time, progesterone can also offset the contraction of uterine muscle, which also contributed to the accumulation of fluid in the womb. If bacterial infection, pus will be formed in the womb. If not, clear uterine fluid will be formed. Experimental study confirmed that exogenous hormone therapy, such as estrogen and progesterone, can also cause uterine fluid - pus. Therefore, you should be cautious when using such hormones to the sterilization of the cat. A plan---tap-meuter-return statistics show that the incidence fo pyometra rate is 0.4%(12/3000).
The main symptoms of the cats suffering from pyometra are: flow or discharge of pus from the vulva, sometimes bloody.
A abdominal circumference increasing manifests itself in anorexia and weight loss. Some even vomiting.
Cat suffering from pyometra the performance of the main symptoms are vulva pus of flow or discharge, sometimes bloody.
Relative poor spirit. As the body absorbs endotoxin, the physical condition becomes more weak.
As the toxin would inhibit the bone marrow hematopoietic function, sick cats will be reflected more severe anemia.
Diagnosis is mainly based on blood, B-ultrasound, X-ray film and so on. WBC can increase significantly up to 3 million or more.
Radiology: Uterine enlargement, no fetus.
B-ultrasound: bladder near the fluid areas, rule out pregnancy.
Vaginal cytology: open – type: a lot of pus; closed-type: the middle layer of nucleated epithelial cells, neutrophils and other white blood cells.
Under the condition when definite diagnosis is made, and the state of the animals is available, operation should be taken as soon as possible to remove the uterus and ovaries. If heavier anemia, bloodd transfusion is needed before the surgery to alleviate the anemia. For the relatively weak animals, correcting the acid-base balance and ion balance are needed to correct dehydration. Since the absorption of endotoxin, kidney toxicity can be caused. Therefore, adjusting the state of good health is very important before surgery. The other problem is the anesthesia. Improper anesthesia on infirm animals can cause death. Terefore, inhalation anesthesia is a good choice. The insulation is also very important during the surgery and the treatment process.
