Cervical balloon dilatation

When every pregnant woman goes to the hospital for a prenatal check-up, the doctor will tell her the specific due date. If the pregnant woman gives birth during the due date, it will be beneficial to both the fetus and the pregnant woman's body. If a pregnant woman has not given birth after the due date, the doctor will recommend that she undergo cervical balloon dilatation to promote delivery, because continuing the pregnancy will cause harm to the pregnant woman's body. Next, the relevant knowledge about cervical balloon dilatation is explained.

1. Benefits of cervical dilation balloon

When continuing the pregnancy is dangerous to the pregnant woman or the fetus, such as delayed pregnancy, post-term pregnancy, oligohydramnios, gestational diabetes beyond the due date, etc., and natural delivery is not possible, the pregnant woman will face two choices: natural delivery or cesarean section to end the delivery. For pregnant women who are qualified for natural childbirth (vaginal childbirth), doctors will recommend that they plan their childbirth, but immature cervical conditions will increase the difficulty of vaginal childbirth. According to Zeng Jingyan, chief physician of the Department of Obstetrics and Gynecology at Yangjiang Maternal and Child Health Hospital, in order to promote natural childbirth and reduce the cesarean section rate among pregnant women, the hospital has recently introduced the technology of cervical dilation balloon catheter to promote cervical ripening, giving pregnant women planning childbirth an additional option and method.

The cervical dilation balloon is a non-drug obstetric device that can safely, naturally and gradually dilate the cervix and increase the success rate of induction of labor. Ripening and dilation of the cervix is ​​achieved by the balloon providing gentle, sustained dilation force at the internal and external cervical os.

2How to perform cervical dilation

1. Routinely disinfect the vulva and vagina.

2. Place a vaginal speculum, expose the cervix, disinfect the vagina, cervix and cervical canal, clamp the anterior lip of the cervix and pull it outward, correct the uterine flexion position to a horizontal position, and use a probe to carefully explore the direction and depth of the cervical canal. After the probe passes through the internal os of the uterus, remove the probe and use a cervical dilator to dilate the cervical canal.

3. The operator holds the dilator in a pen-like manner and gently inserts the dilator into the cervix, leaving the internal os of the cervical canal 1 to 2 cm away. The initial size of the dilator is determined according to the tolerance of the patient's cervix, generally starting from size 2 to 4 and gradually expanding to size 7 to 8 in sequence. When the cervix is ​​tight and has poor elasticity, the stay time of the dilator can be extended. Do not be impatient to avoid cervical laceration.

4. After the operation, remove the dilator, disinfect the cervix, and remove the speculum.
