ClinConnect Summary

This clinical trial is looking at two different ways to provide pain relief during and after outpatient surgery for hemorrhoids. Specifically, the researchers want to see which method is more effective at reducing pain right after the surgery. One group of patients will receive a nerve block using a technique called neurostimulation, while the other group will receive a nerve block guided by ultrasound. Both groups will be monitored for how much pain they feel in the recovery room before they receive any additional pain medication.

To participate in this study, you must be an adult who is scheduled for hemorrhoid surgery under general anesthesia and willing to give your consent to join. However, there are some people who cannot participate, such as those who have had hemorrhoid surgery before, have certain allergies, or are pregnant. If you qualify and decide to join, you can expect careful monitoring of your pain levels after the surgery to help determine which pain relief method works best. This study is not yet recruiting participants, but it aims to find better ways to manage pain for patients undergoing this common procedure.
