Review of the Evaluation and Treatment of Vasovagal Reactions in Outpatient Procedures

BACKGROUND A vasovagal reaction is a commonly encountered event in outpatient procedures. There is a paucity of discussion on vasovagal reactions (VVRs) in the dermatologic surgery literature. However, recent investigations in the physiology, evaluation, and treatment of VVRs have been reported in other specialties. OBJECTIVE A comprehensive review of the physiology, evaluation, treatment, and prevention of VVRs. MATERIALS AND METHODS A search as performed using the PubMed/MEDLINE databases. Search terms included "vasovagal," "vasovagal reaction," "syncope," "reflex syncope," "neurocardiogenic syncope," and "fainting." RESULTS Studies demonstrate greater understanding in the physiology of a vasovagal reaction. Although permanent sequelae are uncommon, it is important to respond in a prompt manner. A variety of treatment and prevention options are presented. CONCLUSION Vasovagal reactions should be carefully evaluated. Additional studies may provide greater data in understanding and managing vasovagal reactions. Address correspondence and reprint requests to: Leonard H.
