Whether it is better to use water capsule or drug insertion for induction of labor needs to be decided according to the condition of the patient, both of them have their own advantages and disadvantages, and cannot be generalized. For pregnant women with a cervical score of less than 6, it is often necessary to promote cervical ripening before inducing labor with oxytocin, and water bladder and drug insertion are commonly used in obstetrics to promote cervical ripening. The advantage of water bladder is that it is safer, but it may lead to infection, premature rupture of membranes, etc. It should not be used in pregnant women with premature rupture of membranes, inflammation of the reproductive tract, placenta praevia and so on. Plugging commonly used drugs for prostaglandin preparations, such as dinoprostenol suppositories, etc., the advantages of the drug is that the drug has a rapid onset of action, to promote cervical ripening effect is strong, in the contractions to meet the requirements, you can quickly take out the drug, but the disadvantage is that it may result in a rapid labor, can not be used for asthma, high blood pressure, history of rapid labor, scarred uterus, etc. Pregnant women who need to induce labor need a doctor to help them. If a pregnant woman needs to be induced to labor, the doctor needs to choose the most appropriate way to induce labor after evaluating whether the cervix is ripe or not, and according to the pregnant woman’s own conditions, such as the presence of complications or comorbidities, and so on.
