No results posted yet for this study

Summary

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.

Conditions

  • Epidural Dosage of Lidocaine Bupivacaine in Lower Limb Surgeries

Interventions

DRUG

Lidocaine-Bupivacaine Epidural Mixture (High-dose Lidocaine)

Intervention 1: Lidocaine-Bupivacaine Epidural Mixture (High-dose Lidocaine) Epidural administration of a total volume of 15 ml containing 10 ml of 0.5% isobaric bupivacaine and 5 ml of 2% lidocaine for anesthesia during lower limb surgery. Intervention 2: Lidocaine-Bupivacaine Epidural Mixture (Low-dose Lidocaine) Epidural administration of a total volume of 15 ml containing 10 ml of 0.5% isobaric bupivacaine, 2.5 ml of 2% lidocaine, and 2.5 ml of normal saline for anesthesia during lower limb surgery. Intervention 3: Bupivacaine Epidural Mixture (Control) Epidural administration of a total volume of 15 ml containing 10 ml of 0.5% isobaric bupivacaine and 5 ml of normal saline for anesthesia during lower limb surgery. These descriptions clearly distinguish the three interventions by composition and total volume.
