Normal contractions have a certain rhythm, polarity and consistency, and have a corresponding intensity and frequency. When abnormalities occur, they are called labor abnormalities and are divided into three types: weak contractions, uncoordinated contractions and hyperactivity, with weak contractions being the most common. How to prevent labor abnormalities during labor? Prevention and treatment of labor abnormalities First of all, we should check in detail whether there is obstruction in labor, and those who have obstruction should be treated accordingly, and those who do not have obstruction should be comforted and encouraged, pay attention to their nutrition and rest, give sedatives if necessary, and pay attention to water and electrolyte balance. For those who have been in labor for more than 24 hours or whose membranes have been broken for 12 hours, antibiotics should be given to prevent infection. After the above treatment, the contractions can generally improve and the labor can be ended smoothly after the mother gets several hours of rest. If not, try the following methods to stimulate and strengthen contractions: 1. Enema or catheterization Hot soapy water enema can promote contractions. Those who have difficulty in urination can be catheterized. 2.Acupuncture Acupuncture Sanyinjiao and Hegu to stimulate the technique, or Hegu point injection of vitamin B125-50mg. 3.Artificial rupture of membranes If the fetal head is articulated and the opening of the uterus is 2-3cm without head-pelvic disproportion, the membranes can be pierced artificially to make the lower part of the dewlap and the lower part of the uterus and cervical tightly to reflexively cause contractions, and the time to break the membranes should be chosen between the second contraction. 4, oxytocin IV, can cause strong contractions, do not use a large amount at once, so as not to cause tonic contractions, resulting in fetal asphyxia and death, can cause uterine rupture. Before use, must exclude cephalopelvic disproportion and fetal malposition. Do not use it if the fetal head is high and floating. Use as follows: Oxytocin 2.5u or 5u in 5% glucose 500ml. Start with 10-15 drops per minute, if no contractions are seen, it can be gradually accelerated, the maximum is not more than 40 drops per minute is appropriate. If the contraction is too strong or the fetal heart rate changes, the drip should be slowed down or stopped. After the above treatment, the contractions will be stronger, the opening of the uterus will be opened and the fetus will be delivered smoothly. If this does not work, surgical assistance should be considered. Regardless of whether the fetus is delivered vaginally or by cesarean section, care should be taken to prevent postpartum contraction bleeding.
