Patient comfort during regional anesthesia.

Regional anesthesia has many advantages, which include low cost, ease of administration, and avoidance of risks associated with general anesthesia. Injection of local anesthetic via a needle as part of a regional anesthetic technique can be a stressful experience. The goal is to produce a relaxed patient who is comfortable and cooperative throughout the duration of surgery. The topics of regional anesthetic techniques, drug combinations, and adjunct measures such as sedation have been described extensively in the literature. The issue of patient comfort has not been reviewed in its entirety. This review seeks to collate known information in a systematic format and provide a framework for patient comfort during regional anesthesia.
