Summary

This trial will test if lidocaine and/or ketamine reduces pain and need for opioids after surgery.

Who is the study for?

Excluded are pregnant or breastfeeding individuals, those needing post-op ventilation, using certain drugs like gabapentin, obese patients (BMI ≥35), people with severe heart failure or communication issues, and those allergic to the study meds.
What is being tested?

What are the potential side effects?
Possible side effects include reactions specific to lidocaine such as cardiac arrhythmias for at-risk individuals and ketamine-related issues like psychiatric disturbances or increased blood pressure in susceptible patients.
