ClinConnect Summary

This clinical trial is investigating the effects of two different local anesthetics, lidocaine and levobupivacaine, when injected near the sciatic nerve in the back of the knee, which is often done to help manage pain during foot or ankle surgeries. The researchers want to find out if using lidocaine helps patients feel ready for surgery faster compared to levobupivacaine. They believe that injecting lidocaine below a specific point of the nerve may speed up the process of getting the area numb.

To participate in this study, individuals should be adults aged between 18 and 80 who are scheduled for elective foot surgery and are in good health (ASA physical status I-III). However, people who are pregnant, have certain health conditions, or have had previous surgeries in that area may not be eligible. Participants will receive either lidocaine or levobupivacaine before their surgery, and the researchers will monitor how quickly the anesthesia takes effect and how effective it is. This trial aims to improve the way pain is managed for patients undergoing these types of surgeries.
