What to do if a female dog has dystocia? The situation of dystocia in dogs must be taken seriously, as it can easily lead to the death of both the mother dog and the puppies. For female dogs that cannot produce naturally, they should be sent to a pet hospital for medical treatment, and puppies should be delivered artificially or by caesarean section. However, caesarean section not only affects the female dog's next pregnancy, but also greatly reduces the number of litters. If circumstances permit, artificial assisted delivery may be given priority.
What to do if a female dog has difficult labor ? Symptoms of dystocia in dogs
The following situations often indicate that dystocia may occur, and a good woman should be prepared immediately to assist in the delivery:
1. The fetal position or fetal potential is very abnormal, such as only one leg is involved Qingdao;
2. Intense labor for 20 to 30 minutes, but no elimination of the fetus was seen; labor was weak, sporadic, lasting 2 to 3 hours;
3. The previous fetus After elimination, no continuous production will be seen for 4 hours (unless production is completed).
If the time between fetal delivery is extended, it is suggested that dystocia may occur, but no definite conclusion can be drawn. Because under normal birth conditions, a fetus is delivered every 10 to 15 minutes, but when the dog's physique is weak or the uterus is interrupted unregulated, it may take several hours to deliver a fetus.
Analysis of the causes of canine dystocia< /p>
1. Dystocia caused by fetal factors
(1)The fetal position is very very
What should I do if a female dog has dystocia? That is, improper fetal position, transverse, vertical, oblique, inferior, lateral, or abnormal fetal position may cause obstruction of the birth canal and cause dystocia.
During the birth process, the position and posture of the fetus in the birth canal are directly related to the birth process. It is rare to have an upright birth in clinical practice (that is, the fetal head is exposed, and the face and two forelimbs are born first. ) The fetal head is too short or too high, and the neck is flexed; the head is turned sideways, with one forelimb inside the birth canal and the other outside the birth canal; inversion delivery (buttocks first, the buttocks and then the two limbs are delivered first ), the two hind limbs are flexed and cannot enter the birth canal, or one hind limb is in the birth canal and the other is outside the birth canal, and the two hind limbs are separated.
(2) Fetal development is very easy to cause dystocia. For example, macrofetus and abnormal fetus are prone to obstructive dystocia. In addition, stillbirth can also easily cause dystocia in bitches. Dystocia.
2. Dystocia caused by maternal factors
(1) The labor force is very severe
The labor force is mainly due to uterine interruption. Throughout the entire production process, the diaphragm, abdominal muscles and abdominal wall muscles are interrupted and the levator ani muscle is interrupted as a supplement. If the factors of the birth tract and fetus are normal, the dilation of the cervix and the exposure of the fetal head during uterine interruption will play a decisive role.
Normal uterine disruption is rhythmic, symmetrical, and has corresponding intensity and frequency. If the uterine interruption loses its rhythm, symmetry, frequency and intensity, it will show that the uterine interruption is tired or too strong, resulting in uncooperative interruption, which will lead to dystocia in the female dog.
(2) The birth canal is very very
The birth canal is small, the cervix, vaginal canal, and vulva are not fully dilated, and the pelvis is not fully dilated, causing dystocia. The osseous birth tract includes the birth canal, pelvis and soft birth tract (lower uterine segment, cervix, vagina). Dystocia will occur in all birth duct abnormalities, but clinically, bony birth duct abnormalities are very rare.
(3) What should I do if my female dog has dystocia? Dystocia due to inappropriate medication
Artificial assistance in canine dystocia
p>1. Dystocia caused by fetal factors
(1) Improper fetal position
First correct the fetal position, and the helper will lift the two hind limbs of the female dog, and the surgeon will Inject 3 to 5 mL of paraffin oil or soybean oil into the vagina of the female dog. After disinfecting the right hand, insert it into the vaginal canal. Use your left hand outside the abdominal wall to push the fetus into the pelvic cavity and then correct the fetal position.
If there are other fetuses in the body, first push the fetus back into the fetal position to make room for correcting the fetal position. For horizontal, vertical, lower, side, and head-to-head positions, it is best to squeeze and massage in one direction with both the inner and outer hands. After the fetal position is corrected, insert the right index finger into the vaginal canal to check.
If the cervix is fully open, the fetal membranes are not ruptured, and the pelvis is normal, the fetal extrusion method can be used, that is, a warm, moist towel is tightly wrapped around the abdomen from the diaphragm and pelvic direction, and the mother's uterus is While the dog's uterus is interrupted, squeeze the fetus. Use your right index finger to pull the fetus' head or buttocks out. Use your hands to lift the female dog's vulva, and use the lubrication effect of oil to pull the fetus out. If you don't succeed once, you can repeat it several times until you succeed. .
(2) Obstructive dystocia caused by excessive fetal size
What should I do if a female dog has dystocia? First, make a lateral incision and cut 2 to 3cm above the vulva to enlarge the caliber of the vaginal canal. When the fetus is close to the vagina, the surgeon uses his right hand to open the labia and expand it to both sides.
Assists massage the uterus through the abdominal wall to promote the orderly interruption of uterine expression. When the uterus is interrupted, press the abdomen to reduce abdominal pressure. When the fetus shows the vulva, the surgeon pulls the fetus with his left hand and pulls the fetus out.
(3) Stillbirth and abnormal fetus
Fetal fragmentation is used to destroy the fetus and reduce its size, making the birth difficult.
The method is to use soapy water for enema, routinely disinfect the vulvar birth tract, and inject 10 to 20 mL of paraffin oil or soybean oil. The surgeon inserts the right index finger into the vagina to determine the position of the fetus. The assistant cooperates with the surgeon outside the abdominal wall to fix the fetal neck. The surgeon withdraws the index finger from the outside of the vulva, and then uses the right index finger to insert the small diamond-shaped hook. Inside the Yin Dao.
At this time, the helper fixes the fetal neck outside the abdominal wall. The surgeon withdraws the right index finger 1 to 2 centimeters, hooks the fetal lower jaw hard, and after checking with the index finger to determine whether the hook is firm, pulls the fetal lower jaw hard.
What should I do if my female dog has dystocia? According to the above method, pull out the fetal skull, neck, forelimbs, etc. in sequence, and finally pull out the fetal pelvis. If there are many stillbirths, after pulling out all the stillbirths according to the above method, in order to prevent the occurrence of septic uterine inflammation and systemic symptoms, use 500 ml of psychological saline, 120,000 units of gentamicin, and 1.6 million units of penicillin for vaginal cleaning. .
2. Dystocia caused by maternal factors
(1) The birth canal is narrow, the cervix, vaginal canal, and vulva are not fully dilated, and the pelvis is not fully dilated, resulting in dystocia. Generally, the delivery period has not yet arrived.
BitchAlthough there were signs of labor, the cervix was not fully dilated. A digital examination found that the boundary between the cervix and vagina had not disappeared, and the pelvis was not fully dilated.
As long as the fetal position is normal, wait patiently for this situation. Perform a digital check every 30 minutes to determine the degree of cervical and pelvic relaxation. When the cervix and pelvis are fully relaxed, the abdominal wall is pressed to promote the orderly interruption of the uterus, and the injected paraffin oil or soybean oil also helps to lubricate the fetus.
(2) When the productivity is insufficient, the abdominal pressure is not enough, and the uterus is weak.
First, abdominal massage, inject oil and lubrication into the birth canal, then apply 5 to 10 units of oxytocin to enhance the force of uterine interruption, and then insert the right index finger into the birth canal, touch the head of the fetus, and terminate in the uterus Time traction is produced.
(3) Improper use of medication may cause dystocia.
First, at the cervix, the pelvis is not fully expanded or the fetal position is not correct. The use of oxytocin causes the uterus to warmly interrupt. Eventually, uterine numbness develops. The second is to use an appropriate amount of oxytocin to cause uterine numbness.
What should I do if my female dog has dystocia? In the above situation, the use of oxytocin should be stopped immediately, followed by massage and hot compress on the abdominal wall to promote blood circulation and restore the uterus to normal. When the uterus contracts normally, a digital examination will be conducted to determine the cause of dystocia, and artificial delivery will be used to deliver the fetus.
The artificial delivery guidelines for bitches with dystocia are “clear diagnosis and treatment, smoothing first, then massaging, correcting the fetal position, leveraging labor force, and slow traction.” Therefore, according to the actual situation of each dog, adopt corresponding methods. As long as the method is suitable, artificial weaning will be successful.
