Orthopaedic anesthesia - part 1. Commonly used anesthetic agents in orthopaedics.

Anesthesia is a broad discipline; for orthopaedic applications, the type and location of the planned orthopaedic procedure is important in the selection of the most appropriate anesthetic agent and technique. The purpose of this overview is to: 1. highlight the role of several anesthetic agents commonly used in an orthopaedic setting and 2. to familiarize the orthopaedist with those techniques of regional anesthesia that have implications for emergency rooms and other ambulatory settings. Because the subject matter is expansive in scope, it is necessary to address each of the above objectives separately, in two different articles. Part 1 describes anesthetic agents, whereas Part 2 encompasses techniques of administering regional anesthesia.
