Comparing two pain blocks for hemorrhoid surgery
Part of Digestive system, Heart & circulation, Pain clinical trials.
This study tests two types of numbing injections (a pudendal block and a sacral ESP block) to see which works better for pain after hemorrhoid surgery. If you're scheduled for this surgery, you might qualify to help find a better way to manage pain.

This study compares two ways to numb the area for hemorrhoid surgery: an ultrasound-guided nerve block near the tailbone (sacral erector spinae plane block) versus a traditional spinal 'saddle block.' The goal is to see which provides better pain relief and fewer side effects.
This study tests whether giving a nerve block (an injection that numbs the area around the buttock) before hemorrhoid surgery can reduce pain after the operation. If you're having this surgery, the nerve block may help you recover more comfortably with less need for strong painkillers.
This study tests whether a nerve block (an injection to numb the area) can reduce pain after outpatient hemorrhoid surgery. It may help you recover with less discomfort.
This trial compares two pain-relief medicines (liposomal bupivacaine and ropivacaine) given during open hemorrhoidectomy surgery. It aims to see which one provides better pain control and recovery after surgery. To join, you need to be having this surgery for advanced hemorrhoids and meet certain health criteria.
This study compares two ways to numb the lower belly and groin area for children having hypospadias repair. It tests if a newer injection method (sacral erector spinae block) works as well as the standard method (caudal block) to control pain during and after surgery.
This trial compares two types of pain blocks (nerve numbing injections) used during laparoscopic abdominal surgery to see which gives better pain relief after the operation. It may help you have less pain and recover more comfortably.
