Comparison of Different Epidural Lidocaine-Bupivacaine Mixtures for Lower Limb Surgeries

This randomized controlled trial will evaluate different epidural lidocaine-bupivacaine mixtures in patients undergoing lower limb surgery at a tertiary care hospital in Karachi, Pakistan. Ninety-six participants will be randomly assigned to one of three study groups receiving different combinations of lidocaine and bupivacaine for epidural anesthesia.

The purpose of this study is to determine which anesthetic mixture provides the most effective anesthesia for lower limb surgery. The study will compare the speed of onset and duration of anesthesia, as well as the effects of the anesthetic mixtures on cardiovascular stability during surgery.

The results of this study may help identify an epidural anesthetic regimen that provides optimal surgical conditions, effective pain control, and stable hemodynamic parameters for patients undergoing lower limb procedures.
