Low versus standard dose numbing medicine for spinal anesthesia
Part of Bones, joints & muscles clinical trials.
This study compares two doses of a numbing medicine given during spinal anesthesia for lower limb surgery in older adults. The goal is to find out if a lower dose works just as well but with fewer side effects.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 65 years of age or older.
- You are scheduled for a non-emergency (elective) surgery on your hip, knee, or leg that will use spinal anesthesia (numbing medicine given through a needle in your back).
- You are in generally stable health (classified as ASA I-III by your anesthesia team).
- You are willing to take part and sign a consent form.
- You do not have any condition that would make spinal anesthesia unsafe (like infection at the injection site, bleeding problems, or certain heart conditions).
- You are not allergic to bupivacaine, and you do not have severe liver or kidney disease.

This study looks at how your position during spinal anesthesia (numbing from the waist down) affects the dose of the numbing medicine (bupivacaine) needed and your blood pressure stability. It may help make anesthesia safer and more comfortable for you.
This trial compares two ways of giving the numbing medicine (bupivacaine) to children during surgery below the belly button. It tests whether dosing based on age or weight provides better and safer pain relief during spinal anesthesia.
This early study tests whether using ropivacaine (a local numbing medicine) in spinal anesthesia is safe and workable for certain lower back operations. If you qualify, it may help doctors refine anesthesia choices for your type of surgery.
This study tests two different strengths of a numbing medicine given through a spinal injection before a bladder scope procedure. It aims to find which strength keeps your heart rate and blood pressure more stable during the procedure.
This study compares two types of anesthesia for below-knee amputation surgery in people with type 2 diabetes. One type is a spinal injection, and the other is a nerve block in the leg. The goal is to see which provides better pain control and recovery.
This trial compares two anesthesia methods for lower limb surgery to find which one works better and is safer. If you are having surgery on your leg, foot, or hip, this study may help improve your recovery experience.
