What are the characteristics of coordinated uterine inertia? What are the characteristics of coordinated uterine inertia? Coordinated uterine atony is also called hypotonic uterine atony, as opposed to uncoordinated uterine atony. The uterine contraction of women with coordinated uterine atony has the characteristics of rhythm, symmetry and polarity, but the uterine contraction force is weak, the intrauterine pressure is low, usually lower than 2.0kPa, and the duration of uterine contraction is short and the interval is long, usually irregular. Although the uterus contracted to the extreme, it did not harden and swell, and the labor process was prolonged.
Management of coordinated uterine atony. Once there is coordinated uterine inertia, cesarean section is needed. As long as the head-basin asymmetry is found, cesarean section and artificial rupture of membrane should be carried out immediately. Coordinated uterine atony can occur in three stages of delivery. In the first stage of labor, the measures to strengthen uterine contraction include artificial rupture of membrane, intravenous injection of diazepam and intravenous infusion of oxytocin. Oxytocin can be injected intravenously to strengthen uterine contraction in the second stage of labor, and ergonovine can be injected intravenously in the third stage of labor. The weak coordinated uterine contraction indicates that the degree of uterine contraction is not strong enough and the intermittent time will be prolonged. The intrauterine pressure needed for delivery cannot be reached, which leads to the difficulty of delivery becoming dystocia. If there is no cephalopelvic disproportion, the fetus is not hypoxic, and the amniotic fluid is not turbid, oxytocin can be used for trial delivery in the future.
Coordinated uterine atony is characterized by polarity reversal of uterine contraction. The exciting point of uterine contraction is not from the uterine horns on both sides, but from one or more impulses of the lower uterine segment. Uterine contraction spreads from bottom to top, with small and irregular contraction amplitude and high frequency. When the uterine contraction is uncoordinated, the bottom of the uterus is not firm, but the lower part of the uterus is firm. During the intermission of uterine contraction, the uterine wall is not completely relaxed. This kind of uterine contraction can not expand the cervix as scheduled, nor can it make the exposed part fall, which is an invalid uterine contraction. It may be related to maternal emotional stress.
With the progress of labor, the uterine contraction gradually increases, the contraction time becomes longer, and the interval time becomes shorter. Strong uterine contraction urges the labor to continue. However, some expectant mothers' contractions do not increase with the labor process, which will inevitably prolong the labor process. This condition is called uterine atony, which is divided into primary and secondary. During delivery, abnormal rhythm, symmetry and polarity of uterine contraction or changes in intensity and frequency are called abnormal uterine contractility. Obstructive dystocia is often caused by abnormal birth canal or fetal factors, which increases the resistance of the fetus through the birth canal and leads to secondary abnormal labor force. Abnormal uterine contraction can be divided into two types in clinic: uterine inertia and excessive uterine contraction, each of which is also uterine contraction coordination and uterine contraction disharmony. Uterine weakness refers to the normal polarity, symmetry and rhythm of uterine contraction, but the uterine contraction is weak and weak, with short duration and long or irregular intermittent time. Uterine atony refers to the normal rhythm, symmetry and polarity of uterine contraction, but the intensity of uterine contraction is decreasing, which leads to the prolonged interval and shortened duration of uterine contraction. The strength is weak at each contraction, the cervix dilates slowly, the delivery time is prolonged, the fetus is threatened and the parturient is exhausted. However, the delay of uterine orifice leads to the delay of labor, which leads to the bladder being compressed between the fetal head and pubic symphysis after the fetal head enters the pelvis, resulting in dysuria and urinary retention; Affect the placenta from the uterine wall, causing postpartum hemorrhage; Increase the risk of fetal hypoxia and trauma. If the parturient is weak due to nervousness and fear of delivery, the prospective father and his family should patiently guide him to relax and finally give birth normally.
The first way to relieve the pain of uterine contraction is to listen to music to relax. Music can relieve the tension of parturient and relieve the pain of uterine contraction. Listening to soothing music helps to divert attention and relieve pain.
The second way is to distract yourself and do other things. If the contractions are more frequent and the pains are getting heavier and heavier, expectant mothers may wish to imagine the scene when the baby is born, or walk more, watch TV, read newspapers, chat with their families and try not to think about the painful things. Family members should also give more comfort and encouragement to expectant mothers. During the period of uterine contraction pain, you can eat some digestible foods, such as milk, eggs, chocolate, noodle soup and so on. In order to maintain abundant energy.
The third method is to relax as much as possible during the contraction. When the expectant mother feels pain during the contraction, she should relax as much as possible, or lie down or lie down, and try to lean back against some soft and comfortable quilts when lying down. Try to relax and take a deep breath.
The fourth method, the use of delivery balls can effectively relieve pain. Don't lie in bed all the time when your body aches. You can get up and walk around and try to do some childbirth exercises, that is, sit on the fitness ball and shake it back and forth, which is also helpful for production.
Fifth, the prospective father can massage to relieve the pain, and the prospective father or family can massage the expectant mother to relieve the tension and pain caused by her contractions before labor. The expectant mother lies on the bed or cushion, and the expectant father or family gently knead the expectant mother's back. Or find a soft and comfortable chair or sofa, with the expectant mother lying half-lying and her head relaxed. The prospective father or family members keep pressing the waist and abdomen of the parturient with their hands. Handle with care.
Heating a bag filled with wheat bran in a microwave oven for a few minutes and then carrying it on your back really helps to relieve the pain caused by contractions. Or you can use a water bottle filled with hot water (not boiled water) instead, carefully wrap it in a towel and carry it on your back. Focusing on your breathing is a good way to spend every contraction. Take a deep breath at the beginning of the contraction and relax when exhaling. Then inhale through the nose and exhale through the mouth to keep the muscles of the mouth and cheeks relaxed. Don't care too much about how deep your breath is, but keep a good rhythm.
