Effect of B-ultrasound on abnormal pregnancy of ewes

2024-09-23 11:04:58 Visits:

Usually, ewes will have clinical symptoms such as abdominal pain, restlessness, and shortness of breath. If the cervical mucus plug has not dissolved at this time, it indicates that abortion may be imminent. Clinically, the following measures are usually taken to treat ewes: intramuscular injection of progesterone: 40 mg, once a day, for 3-5 times. At the same time, intramuscular injection of the sedative chlorpromazine hydrochloride 0.8 mg (kg•bw) to stop the contractions and straining of the ewe. If combined with traditional Chinese medicine, the effect of abortion protection is better for ewes with signs of abortion, such as Baizhu Antai San. After the above treatment, if the symptoms of the ewe still do not improve, the imported sheep B-ultrasound observation shows that the condition worsens as follows: the cervix is no longer closed, the vaginal secretions increase, the fetal sac is prolapsed into the vagina, or the amniotic fluid has broken. At this time, abortion will be difficult to avoid. The pregnant sheep should be helped to expel the uterine fetus and other objects as soon as possible (the measures can refer to the treatment of mummified fetuses and immersion fetuses), and the larger ones should be saved and the smaller ones should be abandoned. After treatment, the imported Sheep B-ultrasound should be used frequently to observe the recovery.

There is a principle for the treatment of mummified fetuses and macerated fetuses: accelerate ovulation, remove after separation, and disinfect and prevent inflammation. Accelerate ovulation, usually through prostaglandin preparations and estrogen dissolving corpus luteum and other methods to promote the dilation of the cervix of pregnant sheep, so as to make the birth canal smooth (lubricant mixed with antibiotics can be injected into the birth canal to lubricate the birth canal), which is convenient for the rapid discharge of uterine contents. Through imported sheep B-ultrasound observation, remove after separation. In the process of the mother animal expelling contents and dead fetuses, remember not to pull hard, and the fetal bones should be taken out slowly (the action should be gentle to prevent damage to the birth canal). If large bones are encountered, they should be broken into small pieces before being taken out. Disinfection and anti-inflammation, after the contents are discharged, wash the mother animal's uterus with disinfectant or 10% saline with antibiotics, and inject some oxytocin in an appropriate amount (which is conducive to the return of the uterus and the discharge of residual fluid). For abortion caused by fetal maceration, it is strongly recommended to inject antibiotics into the uterus and give systemic fluid therapy to prevent postpartum sequelae.
