With the development of the dairy industry, while the production performance of dairy cows is increasing, the obstetric diseases of dairy cows are gradually increasing. Caesarean section surgery is often used in the treatment of obstetric diseases in dairy cows. This article focuses on several issues that should be noted in caesarean section of dairy cows. First, the indication of surgery Caesarean section surgery is mainly applied to the following aspects: 1 pelvic bone abnormalities; 2 too large a fetus; 3 severe malformation, fetal orientation, abnormal fetal position; 4 uterine torsion; 5 twin dystocia; 6 other conditions requiring caesarean section. Second, the timing of surgery From practical experience, as long as the diagnosis is as follows and the fetus is still alive, surgery should be performed immediately to ensure that the mother and child are safe. 1 uterus torsion; 2 fetus into the hard birth canal, artificial midwifery, but can not push the fetus to uterine correction; 3 twin dystocia. Third, the surgical site The choice of surgical part has a great influence on the effect of caesarean section surgery. From the current surgery, there are the following 3 parts. 1. The left part, according to "practical veterinary experience compilation" written by the surgical site, should be in the left side of the axillary triangle of the rumen down to a straight line to 17 to 20 centimeters, which began to down the direction of the ribs The incision is 30 to 35 cm long and the end point is generally 7 to 9 cm below the 10th to 11th ribs. 2. Right under the abdomen, the incision site in the right side of the lower abdomen and the right breast vein 5 to 8 cm, incision length of 25 to 30 cm. 3. The right fetal palpation of the right abdominal wall is the most obvious place, usually 20 cm down in the right armpit, vertical 20-30 cm incision. From the above three kinds of incision sites, the left part of the abdominal cavity after the open, remove the uterus, a huge rumen can effectively prevent the bowel from prolapse, save the operation time, but in veterinary practice, the uterus is sometimes not in the abdominal cavity, but in the net In the crypt in the membrane (about 60%), it is very difficult to remove the left side of the membrane, especially when the cow's body is too large and the operation time is delayed. When taking the right abdominal incision, it is easier to remove the uterus because of the proximity of the ion chamber in the incision site. However, if the fetus is facing the incision in the womb, it is not possible to hold the fetal head or head in the hand, and sometimes it is necessary in the upper abdominal wall. Doing an incision can only pull the uterus out of the incision. In addition, the tension in the abdominal incision is large. It is also more difficult to suture than other incisions (tension is large), and it is easy to infect; and the right abdominal wall incision can effectively avoid the disadvantages of the above incision, saving 30% of the operation time, improve the success rate of surgery, it is worth veterinary practice to promote. Fourth, anesthesia method Try to use local anesthesia to avoid general anesthesia. At present, the general anesthetic used, whether by Jingsongling or Shennengning, can enter the fetus through the placental barrier from the point of view of drug body dynamics, inhibit the weakened heart, respiratory and nervous system of the fetus, and increase the mortality rate of fetuses delivered by caesarean section. The use of 2% lidocaine for parasinal nerve conduction anesthesia, with chlorpromazine can effectively avoid the occurrence of the above conditions, to achieve both sure indeed, but also to prevent the death of the fetus. Fifth, pay attention to the problem 1. In the case of caesarean delivery, 3 to 4 individuals must work together to cooperate with each other during the operation to achieve the shortest possible time to complete the operation and ensure the survival rate of the fetus. 2. Prior to surgery, according to the body condition of the cow, in order to prevent excessive bleeding, certain hemostatic drugs should be injected. To prevent infection, antibiotics are required before, during, and after surgery. 3. After pulling out the fetus, if the fetus is weak and suffocates, don't break the umbilicus first, and then hold the umbilical cord with one hand so that the blood in the placenta flows into the fetus and presses the chest of the fetus at the same time. Caesarean section of the fetus due to lack of oxygen in the uterus, pull out and timely intramuscular injection of sodium 1 ~ 2 grams, improve fetal survival rate. In addition, after removing the fetus, if the fetal clothing should not be stripped, can be injected in the uterus 10% saline 500 to 1000 ml, after surgery, intramuscular injection of oxytocin 100 units, prompting discharge of the placenta.
