The period of time between the opening of the uterus and the delivery of the fetus is also known as the period of fetal delivery. It is also known as the second stage of labor. Normal labor takes about 1-2 hours for primigravid women and less than 1 hour for transient women, and is usually completed in a few minutes. Proper assessment and management of the second stage of labor is critical to maternal and fetal outcomes. Given that prolonged duration of the second stage of labor is associated with increased adverse maternal and fetal outcomes such as postpartum hemorrhage, puerperal infections, severe perineal lacerations, neonatal asphyxia, and infections. Therefore, the management of the second stage of labor should not only consider the duration of the second stage of labor, but should also focus on fetal heart rate monitoring, contractions, fetal head descent, the presence of cephalopelvic disproportion, and the general condition of the mother. Fetal heart rate should be closely monitored during the second stage of labor, and attention should be paid to assessing the relationship between fetal heart rate and contraction after each contraction, etc., and distinguishing between fetal heart rate and maternal heart rate. If abnormal fetal heart rate is detected, a vaginal examination should be performed immediately to comprehensively assess the progress of labor and end the delivery as soon as possible. Pregnant women should pay attention to the prenatal checkup during pregnancy, and actively listen to the advice of professional doctors to do a comprehensive care and health care work, which can effectively ensure the safety of labor.
