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.
