How many times can I perform fallopian tube intubation?

If the effect of fallopian tube insufflation is not good after one try, you can consider doing it again. We know that fallopian tube disease is relatively common in infertility cases. It often leads to fallopian tube adhesion and fallopian tube blockage. Both of these conditions can cause infertility in women. At this time, you can consider fallopian tube insufflation. As for how many times it needs to be done, it depends on the specific condition.

How many times can I perform fallopian tube intubation?

The number of times the fallopian tube insufflation is performed depends on the specific condition. The process of fallopian tube insufflation:

1. The patient's bladder is in lithotomy position after urination. The vulva and vagina are routinely disinfected, covered with sterile towels, and a bimanual examination is performed to understand the position and size of the uterus. Place a vaginal speculum to expose the cervix, disinfect the vagina and cervix again, clamp the anterior lip of the cervix with a cervical clamp, insert a cervical catheter along the direction of the uterine cavity, and make it fit tightly against the external os of the cervix.

2. Connect the cervical catheter to the pressure gauge and syringe with a Y-type pipe. The pressure gauge should be higher than the level of the pipe to prevent the injection fluid from entering the pressure gauge.

3. Fill the syringe with 20 ml of sterile saline (containing 80,000 units of gentamicin) and inject slowly. The pressure should not exceed 26.6 KP (200 mmHg). If the fallopian tube is blocked, the patient will feel pain in the lower abdomen when 4-5 ml is injected. At this time, the pressure on the pressure gauge will continue to rise and not drop. If the fallopian tube is unobstructed, 20 ml of sterile saline is injected without any resistance, and the pressure is maintained below 8.0 kPa (60-80 mmHg). The patient does not experience abdominal distension or discomfort, and the pressure drops rapidly on its own after the injection stops, indicating that the injected liquid has successfully entered the abdominal cavity. The experiment was repeated and the situation was the same. You can also use a syringe to directly push the injection into the cervical catheter without a pressure gauge. If 20 ml of sterile saline is slowly injected without resistance and the patient feels no discomfort, it confirms that the fallopian tube is unobstructed. If resistance is felt when 10 ml is injected with difficulty, the patient will experience lower abdominal distension and pain, and the liquid will flow back into the syringe after the injection stops, indicating that the fallopian tube is blocked. If it can be pushed forward again after pressurized injection, it means that the original mild adhesion has been separated. If you want to identify which fallopian tube is blocked, you can place a stethoscope on the lower abdomen at the level corresponding to the fallopian tube during the fluid flow process. If you can hear the sound of fluid passing through water, it indicates that the fallopian tube on that side is unobstructed (but these are all conjectures, and their reliability is subject to certain limitations).

4. After the operation, remove the cervical catheter, disinfect the cervix and vagina again, and remove the vaginal speculum.

Who should not undergo fallopian tube insufflation?

(1) Menstrual cycle disorders have not been corrected.

(2) Presence of genital tumors in the pelvic cavity.

(3) Inflammation of reproductive organs: acute stage or chronic recurrent stage, which cannot be controlled by drug treatment.

(4) Those who are in poor general condition, have serious lesions of the heart, brain, lung, liver, kidney and other important organs, or have diseases that are contraindicated for pregnancy.

(5) The male partner is clearly infertile.
