Ketamine Plus Spinal Anesthesia for Older Adults Undergoing Leg Surgery
Treatments studied
Part of Pain clinical trials.
This study tests whether adding ketamine (a type of anesthetic medication) to spinal anesthesia—numbing medication injected near the spine—can make the numbness last longer for older adults having leg surgery. The goal is to see if this combination improves pain control after surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 65 years old or older
- You are scheduled for elective (planned, not emergency) leg surgery using spinal anesthesia
- You do not have a pre-existing neurological disorder (such as Parkinson's disease, multiple sclerosis, or neuropathy)
- Your blood clots normally (platelets above 60,000 and INR 1.5 or lower)
- You have no infection at the site where the spinal needle would be inserted
- You are not allergic to ketamine or any other medications used in this study

Other trials that look related to this one.
This trial tests whether a medicine called S-ketamine (a type of anesthetic) can safely improve recovery in older adults during major surgery. Participating may help reduce pain and confusion after surgery.
This study tests if giving ketamine during certain back surgeries affects how well doctors can monitor your spinal nerves during the operation. It's for adults having a posterior spinal fusion.
This study tests if a low dose of ketamine (a pain medicine) given before spinal anesthesia can prevent dangerously low blood pressure during orthopedic surgery. It might help keep your blood pressure steady, making the procedure safer.
This trial tests whether giving a medication called ketamine during heart surgery can reduce long-term pain after the operation. If it works, patients may recover with less chronic pain.
This study tests whether adding a medicine called dexmedetomidine to spinal anesthesia can make the numbness last longer after knee or hip replacement surgery. It may help reduce pain after surgery without extra side effects.
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.
