tubal ventilation

Fallopian tube ventilation uses special instruments to inject gas (air, oxygen or carbon dioxide gas) into the uterine cavity from the cervix to determine whether the fallopian tube is unobstructed. Treatment of diseases: tubal obstruction infertility Indication 1, a variety of primary or secondary infertility. 2. After infertility surgery, prevent adhesion formation and measure the surgical effect. 3. Unblock the mild adhesion of the fallopian tubes. 4. The therapeutic fluid is started 3 to 4 days after menstruation, 6 times for 1 course of treatment, and 1 course of treatment per month. The drug is 400,000 U of penicillin and 0 to 5 g of streptomycin (all need to be tested first). Hyaluronidase 150 U or acetic acid cortisone 50 mg was dissolved in physiological saline 8-10 ml, and further angiography was performed after 3 courses to determine the therapeutic effect. Contraindications 1. The menstrual cycle disorder has not been corrected. 2. There is a genital tumor in the pelvic cavity. 3, genital inflammation in the acute phase or chronic recurrent episodes, drug treatment has not been controlled. 4, poor general condition, there are serious heart, brain, lung, liver, kidney and other important organ lesions. 5, has been identified as the male infertility. Preoperative preparation 1, time selection after menstruation clean 3 ~ 7d. 3 days before surgery, banned sex life. 2, confirmed by various examinations are indeed not pregnant. 3, preoperative examination of leucorrhea routine, blood, urine routine and body temperature, blood pressure. Surgical procedure 1. Empty the bladder, take the bladder lithotomy position, disinfect the vulva and vagina, and sterilize the surgical towel. 2, double examination to understand the size, azimuth, texture, activity, shape and relationship with the surrounding organs, the attachments on both sides are abnormal. 3. Place the speculum, expose the cervix, disinfect the vagina and the cervix, clamp the front lip with a cervical clamp, and pull outward to make the uterus horizontal. 4, with the uterus probe in the direction of the uterus gently probe the bottom of the palace, measure its depth and confirm the degree of flexion and size and check whether the resistance is not strong, you can change the direction to find the position of the uterine cavity without resistance and variation. It is clear whether there is a feeling of resistance to the probe caused by unevenness or adhesion of the inner wall and tumor compression. 5. Check that the ventilation device is perfect and should not leak air. 6. Insert the uterine ventilation catheter into the neck tube according to the direction of the probe detection and fix it at a previously selected depth. The anterior lip of the cervix is clamped with tissue clamps, and the conical head of the inflation catheter is pushed inward while pulling the cervix outward. The two are tightly fitted, and the air can be squeezed by the air to gradually increase the pressure to 26, 66 kPa ( 200mmHg); if CO2 ventilation device, open the valve, the pressure is controlled at 39, 9 ~ 53, 2kPa (300 ~ 400mmHg), so that the gas enters the uterine cavity.
