Researchers studied whether adding a local anesthetic injection to the cervix (cervical blockade) during general anesthesia could help patients having a procedure called LEEP to remove abnormal cervical cells. They compared 20 patients who received the cervical blockade plus general anesthesia to 20 patients who received general anesthesia alone. All patients had been diagnosed with high-grade squamous intraepithelial lesion (HSIL).
The study found that patients who received the cervical blockade reported significantly less pain after surgery. They also had less bleeding during the procedure, as measured by how many surgical sponges were used. However, there was no difference between the two groups in other important measures. These included the size of the tissue removed, whether all abnormal cells were successfully cut out, changes in blood counts, or whether patients needed to be readmitted to the hospital.
This was a small, early-stage trial with only 40 patients. The doctors and patients knew which treatment was being given, which can sometimes influence results. The study did not report on any safety concerns or side effects from the cervical blockade. While the findings suggest this approach might improve comfort during this specific surgery, much larger studies are needed to confirm these results and understand if there are any risks.
