Clinically Important Pharmacologic Considerations for Wide-Awake Local Anesthesia No Tourniquet Hand Surgery

Understanding the clinically important pharmacokinetics (what the body does to the drug) and pharmacodynamics (what the drug does to the body) of medications used in surgery will help surgeons use them more safely and effectively. The goal of this article is to provide an overview of these considerations for the 2 medications used in wide-awake local anesthesia with no tourniquet upper extremity surgery (ie, lidocaine and epinephrine) to establish a better understanding of lidocaine and epinephrine in tumescent local anesthesia, as well as adverse reactions and how to manage them.
