This trial tests whether using a laser to ablate (destroy) specific nerves around the knee provides better pain relief than the standard radiofrequency method for people with chronic knee osteoarthritis. Fifty adults with persistent knee pain will receive one of the two procedure…

This trial compares two ultrasound-guided nerve blocks—serratus-intercostal and erector spinae—both using a mix of bupivacaine and dexmedetomidine to control pain after mastectomy. The goal is to see which block reduces the need for morphine and improves pain scores. Seventy wome…

This study tests a new ultrasound-guided pain block for high-risk children (ages not specified) having anal or penile surgery. The goal is to see if this block can delay or replace strong pain medicines that can cause breathing or heart problems. Sixty children will be enrolled, …

This study tests whether a combination of ketamine and dexmedetomidine (Ketodex) works faster and safer than the usual propofol-midazolam for sedation during upper GI endoscopy. Fifty-two adults aged 21–60 will be enrolled. Researchers will measure how quickly patients reach the …

This study tests two ways to numb the knee after total knee replacement in 50 elderly patients. One method combines two nerve blocks, the other uses a single block. Researchers will measure how long pain relief lasts and how much extra pain medicine is needed. The goal is to find…

This study tests whether intravenous lidocaine or magnesium sulfate can better stabilize blood pressure and heart rate as women wake up from general anesthesia during infertility-related laparoscopic surgery. Sixty-nine women will be randomly assigned to receive one of the two dr…

This study compares two nerve block techniques—dual external oblique fascial plane block and erector spinae plane block—for pain control after percutaneous nephrolithotomy (PCNL), a surgery to remove large kidney stones. Ninety adults will be randomly assigned to receive one of t…

This study compares two drug combinations given through an IV to manage pain after vaginal hysterectomy. 50 women will receive either dexmedetomidine alone or with ketamine. The goal is to see which provides better pain relief and reduces the need for extra painkillers in the fir…

This study will compare two ultrasound-guided nerve block techniques (subcoracoid tunnel block vs. costoclavicular block) in 70 elderly patients having surgery on the hand or forearm. The goal is to see which method provides faster pain relief, longer-lasting comfort, and reduces…
