Brugada Syndrome: anesthetic considerations and management algorithm

Brugada Syndrome is characterized by arrhythmogenic risk that may be exacerbated by different metabolic and pharmacological factors. Since its first description, knowledge of this syndrome and its detection by physicians belonging to different specialties have gradually increased. The risk of arrhythmias is well known to increase in the postoperative period, and this risk is particularly accentuated in patients with Brugada Syndrome. The purpose of this review is to analyze the relationship between this syndrome and anesthesia; establish recommendations for the safe management of these patients in the surgical setting; and update the relevant concepts regarding the safety of drug administration in individuals with Brugada Syndrome.

Brugada Syndrome Induced by an Interscalene Block: A Case Report

CASE

A 57-year-old woman with no noteworthy medical or surgical history underwent an interscalene block with bupivacaine in preparation for an arthroscopic rotator cuff repair. Following administration of the bupivacaine, the patient sustained a ventricular fibrillation arrest. After successful cardiopulmonary resuscitation, she was diagnosed with Brugada syndrome. An implantable cardioverter-defibrillator was placed, and the rotator cuff repair was performed 1 month later.

CONCLUSION

Brugada syndrome is an abnormality of the cardiac conduction system that leads to cardiac arrhythmias. Several anesthetic agents trigger Brugada-like electrocardiographic abnormalities. To our knowledge, this is the first report of an interscalene block inducing Brugada syndrome.
