laser coagulation

Laser coagulation cervical erosion, has the characteristics of simple, rapid, high efficacy; at the same time the laser knife does not touch the tissue, easy to grasp the depth of the burning tissue, so fewer complications. Cervical erosion is commonly used as a CO2 laser. More solidification carbonization or oxidation is used. For the cervical erosion with a small power CO2 laser, burning on the erosion surface carbonization, usually a cure. Treatment of diseases: cervicitis cervical erosion Indication Laser coagulation is suitable for moderate and severe cervical erosion. Contraindications 1, suffering from acute inflammation of internal and external reproductive organs such as trichomoniasis or fungal vaginitis, acute pelvic inflammatory disease need to be cured before surgery. 2, there are systemic diseases, such as severe heart disease, liver disease, blood disease, etc. should not be treated surgically. 3, cervical invasive cancer. Preoperative preparation 1, detailed medical history, physical examination and gynecological examination, including testing vaginal discharge. And explain the precautions to the patient. 2, cervical scraping or cervical biopsy to exclude cancer or other specific inflammation such as tuberculosis. 3, the operation time is generally carried out 3 to 7 days after menstruation. Asexual life history within 3 days before surgery. Surgical procedure 1, take the bladder lithotomy position, expose the cervix, routine disinfection. 2. After adjusting the power and focal length (the general power is 40W, the spot is 6mm parallel beam), the operator holds the CO2 laser cutter head, the light guide tube is aligned with the cervical lesion, the foot switch is centered on the neck, and the inside is burned from the inside to the outside. It can be seen that the smashed surface is rapidly carbonized and gasified. The burning range can exceed 1 to 2 mm of the cervical erosion surface. 3, the wound surface cleaned, partially coated with 1% gentian violet and furancilin powder. complication 1, cervical wound bleeding. 2, infection. 3, cervical tube adhesion or stenosis.
