LOT fetal position is left occipital transverse position, most of them can be delivered smoothly, but the fetal position is normal in LOT, but the fetal orientation is abnormal, this fetal orientation can be changed to left occipital anterior position or right occipital anterior position with the strengthening of contractions during labor. In the process of vaginal delivery, it is necessary to monitor the progress of labor, and if it can be changed to left occipito-anterior or right occipito-anterior position with the contraction of uterus, the fetal head can be delivered smoothly through the pelvis. If the fetal position is persistently left occipito-transverse during labor and cannot be changed to left occipito-anterior or right occipito-anterior position, the fetus cannot be delivered vaginally and the delivery needs to be ended by cesarean section in time. During the progress of labor, it is found that the fetal heart rate varies too much and there is obvious intrauterine hypoxia, and if it is considered that labor cannot be ended within a short time, it is also necessary to take appropriate methods to assist labor or end labor by cesarean section.
