What are the reasons for poor uterine contraction?

In fact, uterine contractions are divided into two types clinically. The first type is true uterine contractions, and the second type is false uterine contractions. If the former is normal, it is conducive to natural delivery. If it is the latter, it is definitely necessary to find the cause and then deal with it correctly. Clinically, some women's uterine contractions are not very good, so what are the reasons for this?

1. The placenta or fetal membranes remain in the uterine cavity. After delivery, the delivery of the placenta and fetal membranes must be handled correctly. The delivered placenta and fetal membranes should be carefully checked to see if they are intact, and attention should be paid to checking whether there are broken blood vessels on the edge of the fetal surface of the placenta. If there is still residual placenta or fetal membrane tissue in the uterus, or the uterus contracts poorly, it will affect the speed of uterine recovery. The recovery status of the uterus can be judged by observing the color, amount and smell of lochia discharge. Under normal circumstances, the amount of lochia will become less and less, the color will become lighter and lighter, and it will end in about 3 weeks. Excessive lochia is abnormal.

2. If improper care is given after delivery, it may cause uterine or pelvic infection and long-term bleeding.

3. Under normal circumstances, the female vagina is acidic and the cervix has a mucus plug, which is the body's physiological barrier that can resist bacterial invasion. However, under special circumstances, such as menstruation, childbirth, after abortion and various intrauterine operations, this barrier function is weakened or even disappears, which can easily lead to bacterial invasion, cause endometritis, and affect postpartum uterine recovery.

4. In the late pregnancy, the enlarged uterus presses on the bladder, reducing the tension of the bladder muscles. During delivery, the fetal head presses on the bladder tightly for a long time, weakening the contraction of the bladder muscles. Therefore, although the pressure of the uterus on the bladder is reduced after delivery, the bladder is no longer able to expel the urine due to the decrease in bladder muscle tension and weakened contraction function. In addition, some women underwent episiotomy during delivery. When urinating, urine irritates the wound and causes pain, leading to spasm of the urethral sphincter, which is also the cause of difficulty urinating after delivery. Some women are not used to urinating in bed, which can also cause difficulty urinating. If you still cannot urinate within 5 to 6 hours after delivery, doctors call it postpartum urinary retention. Poor urination after childbirth can also affect uterine recovery.
