Adding sedation drugs to spinal block to prevent urine retention after leg surgery
Part of Bones, joints & muscles, Kidney & urinary, Pain clinical trials.
This trial tests whether adding dexmedetomidine or fentanyl to the standard spinal anesthesia medication helps prevent trouble urinating after leg surgery. If you qualify, you'll get one of these added to your spinal block, and the study will watch how your bladder function recovers.
Summary written for real people, not researchers, by Clin2.

This study tests whether adding a medication called dexmedetomidine to spinal anesthesia can make pain relief last longer and work better. This could help reduce pain after your leg or foot surgery.
This trial tests adding dexmedetomidine (a calming medication) to bupivacaine (numbing medication) injected into the spine during knee surgery. The goal is to improve pain relief and recovery after surgery.
This study tests whether giving a drug called dexamethasone before spinal anesthesia shortens how long the numbing and muscle relaxation last. The goal is to help you recover feeling and movement sooner after surgery.
This trial tests adding two medicines (dexmedetomidine and fentanyl) versus fentanyl alone to the standard spinal anesthetic for above-knee amputation surgery for lower limb sarcoma. The goal is to see if the combination provides better pain control during and after surgery.
This study tests whether two medicines, dexmedetomidine and esketamine, can reduce discomfort from a urinary catheter after bladder or prostate surgery. If you are having this type of surgery and need a catheter, this trial may help find a better way to manage that discomfort.
This study compares two medicines (dexmedetomidine and fentanyl) added to a spinal numbing shot for people having planned leg or knee surgery. The goal is to see which one works better to keep your blood pressure stable, and to make the numbing last while keeping you comfortable.
