How to prevent incomplete uterine aspiration during abortion surgery

Incomplete aspiration refers to the residual of some pregnancy tissue after artificial abortion. If a woman bleeds for more than 10 days after abortion, the amount of bleeding is heavy, or there is heavy bleeding again after the bleeding stops, it should be considered as incomplete aspiration. Its occurrence is related to factors such as the operator's unskilled skills, excessive uterine curvature and uterine malformation. By understanding the causes of its occurrence, targeted methods can be taken to prevent it. Relevant measures include:

1. Operators should strengthen their sense of responsibility and improve their technical level

It is recommended to routinely use prostaglandin preparations to relax the cervix before surgery; use a transparent silicone tube as a suction tube connection during surgery, which helps the operator observe the amount of embryonic tissue sucked out and helps to preliminarily determine whether the suction is complete. Use a curette to check during surgery, especially to check whether the uterine horns on both sides are scraped clean, and carefully check whether the embryonic tissue is complete before the end of the surgery.

2. Treatment of uterine malformation

Common uterine malformations include didelphys, bicornuate uterus, complete or incomplete septate uterus, etc. Therefore, relevant examinations should be performed before surgery to understand the patient's uterine condition. If conditions permit, the operation should be performed under B-ultrasound guidance; if conditions do not permit, the chorionic villi and decidua should be checked before the end of the operation. Generally speaking, patients with bicornuate uterus have more decidua. If no villi or less decidua are found, the patient should be re-examined to avoid incomplete uterine aspiration.

3. Treatment of excessive uterine flexion

If the uterus is excessively anteflexed or retroflexed, it can be corrected by double-handed reduction or traction of the cervix. If reduction is not possible, it is best to perform surgery under the guidance of B-ultrasound. If conditions are unavailable, carefully check whether the villi are intact before the end of the operation.
