Adding sodium bicarbonate to numbing medicine for hand or foot surgery
Part of Pain clinical trials.
This trial tests whether adding baking soda (bicarbonate) to the numbing medicine (lidocaine with epinephrine) reduces pain during hand or foot surgery. It might make the local anesthesia work better and reduce the burning sensation when it is injected.

This trial compares two methods of numbing pain—an injection near the joint versus a nerve block—during ankle or hindfoot surgery. It aims to see which approach helps with comfort and recovery after surgery.
This study looks at hand surgeries done using a special numbing medicine that lets you stay awake without a tourniquet (a band that stops blood flow). The goal is to help you have a comfortable experience and maybe a quicker recovery.
This trial tests whether a long-acting numbing medicine called liposomal bupivacaine, given through a nerve block, reduces the pain that can return after the block wears off following orthopedic surgery. If you're having arm or leg surgery, this could help you feel better and need less pain medicine.
This trial tests whether injecting a long-acting numbing medicine near the surgery site can reduce pain after brain surgery for nerve compression. If it works, patients may have less pain and need fewer painkillers after the procedure.
This trial tests a regional anesthesia (numbing medicine given near nerves) during minimally invasive lumbar spine surgery. The goal is to see if it helps control pain around surgery and improves recovery comfort.
This study tests a new way to manage pain after hand surgery using local numbing medicine with a special clotting agent, aiming to reduce the need for opioid painkillers.
