OBJECTIVE:

To compare the advantages and benefits of paracervical block vs conventional anesthesia for manual vacuum aspiration in patients with incomplete abortion and endometrial hyperplasia.

MATERIALS AND METHODS:

An analytical, comparative and retrospective study was carried out in patients with a diagnosis of incomplete abortion in the first trimester or endometrial hyperplasia who underwent manual vacuum aspiration under paracervical block or regional anesthesia, treated at the tochosurgery service in the Obstetric-Gynecology Department.

RESULTS:

We analyzed 144 files of patients with a diagnosis of incomplete first trimester abortion and endometrial hypertrophy operated by paracervical block (53.47%) and epidural block (46.53%). The indication for manual vacuum aspiration was: endometrial hyperplasia in 40.97% and for incomplete abortion 59.03%. Pain was mild in 57.14%, moderate in 38.96% and severe in 3.90%.

CONCLUSION:

In patients in whom manual vacuum aspiration was performed, the effectiveness of paracervical block was less than with conventional anesthesia in the control of postoperative pain. In patients with incomplete spontaneous abortion no statistical difference was found in postoperative pain between analgesic techniques. Therefore, paracervical block may be an alternative in the care of these patients, especially when the resources and infrastructure necessary to administer an epidural block are not available.
