Ultrasound-Guided Versus Landmark-Guided Pudendal Block for Post-Hemorrhoidectomy Pain

Hemorrhoid surgery is often followed by significant pain during the first few days after the operation. Pudendal nerve block is a pain-control technique that can help reduce discomfort after surgery. This study will compare two different methods of performing a pudendal nerve block: an ultrasound-guided method and a conventional landmark-guided method. Patients undergoing Milligan-Morgan hemorrhoidectomy will be randomly assigned to one of the two techniques. The study will evaluate postoperative pain levels, pain medication use, treatment-related complications, and patient satisfaction. The study hypothesis is that the ultrasound-guided technique may provide better pain relief and reduce the need for additional pain medication compared with the landmark-guided technique.

Ultrasound-Guided Pudendal vs Dorsal Penile Nerve Block for Pediatric Hypospadias Surgery

The goal of this clinical trial is to compare the effectiveness and safety of two regional anesthesia techniques, ultrasound-guided pudendal nerve block and dorsal penile nerve block, for postoperative pain management in children undergoing hypospadias surgery. The main questions we aim to answer are: Which technique provides more effective pain relief after surgery? What are the potential side effects or complications associated with each technique? Participants will: Receive either an Ultrasound-guided pudendal nerve block or a dorsal penile nerve block in combination with general anesthesia after surgery. Participants will be monitored for pain levels using a pediatric pain scale Face, Leg, Activity, Cry, Consolability (FLACC) and their overall recovery for the first 24 hours post-surgery. Have their total analgesic consumption and vital signs recorded during the recovery period. This study will help improve postoperative pain management strategies for pediatric hypospadias surgery by evaluating these two anesthesia techniques.
