Scraping and cleaning are both relatively common gynecological procedures, and many people think that scraping and cleaning are the same procedure, but in fact they are not. There is a difference between the two. Scraping is the process of removing the contents of the uterine cavity, such as the gestational sac and the endometrium, while purging is the process of removing residual material from the uterine cavity after scraping. Scraping is very effective for intrauterine pregnancies within 70 days of gestation, while curettage can be used in cases where there are residues in the uterine cavity after scraping, placenta residues after delivery, and excessive blood clots in the uterine cavity. The scraping of the uterus requires the use of a cervical aspirator, but the cleaning of the uterus is a mechanical operation, and the use of a scraping spoon depends on the experience and skill of the clinician. The time required for both curettage and evacuation is basically the same, taking about 3-5 minutes to complete, and they both have the same level of pain and the option to inject anesthetic medication during the procedure. Both procedures are inevitably harmful to the lining of the uterus. In simple terms, a curettage is a complementary procedure to a curettage, but it is more widely available than a curettage. Both procedures require an infusion of anti-inflammatory fluids to prevent infection in the uterine cavity.
