Induction of labor with small water sac

Induction is the use of surgical methods to induce uterine contractions, and termination of pregnancy. Indications for induction of labor: pregnant women or fetuses should not continue their pregnancy due to the condition of termination of pregnancy. Common reasons are: 1. Pregnancy-induced hypertension/hypertension. 2. Pregnancy complications should not continue to be pregnant, such as chronic kidney disease, heart disease, diabetes, liver disease. 3. Those with placental dysfunction, such as expired pregnancy, intrauterine growth retardation. 4. Premature rupture of membranes. 5. Too much amniotic fluid and too little amniotic fluid. 6. Fetal malformation, stillbirth. 7. It is also possible to arrange for the timely induction of labor due to non-medical reasons, but it is currently not advocated. Commonly used methods include artificial stripping, artificial rupture, and small water sac induction. With the development of perinatal medicine, planning and timely termination of pregnancy for high-risk pregnancies is an important issue. Induction of labor in small water sacs can be performed on vaginal delivery conditions in the fetal head at the end of pregnancy. It is a simple, safe and effective method of induction of labor. Treatment of diseases: abortion Indication Small water bladder induction surgery is applicable to: Expired pregnancy, pregnancy-induced hypertension syndrome, intrauterine growth retardation, placental dysfunction, and other indications may be performed in patients who need to terminate the pregnancy, but must be connected or partially connected and the membrane is intact. Contraindications 1. Have a history of vaginal bleeding or B-ultrasound diagnosis of placenta previa. 2. Acute genital inflammation and severe erosion of the cervix. 3. The uterus has scars. Preoperative preparation 1. Take cervical secretions for bacterial culture and drug sensitivity. 2. Cervical score. 3. Prepare a sterile small water bladder. Use a double-layer condom (discharge the air between the two layers) or a small balloon, tie it on the 12th rubber catheter, and ligature it with a thick thread at 5cm and 8cm from the head. Boiled or autoclaved before use. 4. Pregnant women urinate on their own. Surgical procedure 1. Expose the cervix with a vaginal speculum, wipe the vagina and cervical secretions, sterilize the cervix with iodine, ethanol or iodophor, hold the anterior lip of the cervix with a cervical pliers, and apply a sterile lubricant to the small water sac. Pliers or non-toothed bending pliers clamp the small water bladder into the side wall of the uterine cavity, and stop when the second knot enters the external cervix. At this time, it indicates that it has been placed 8cm, and 100ml of normal saline is added to add the macromycin. Wan U forms a small water sac, the lower edge of which has reached the upper end of the cervix, and finally the end of the catheter is ligated with a wire. 2. Remove the cervical forceps and wrap the end of the catheter with sterile gauze into the vagina. 3. Remove the vaginal speculum. complication Calving infection.
