Peripheral nerve block with ropivacaine in Brugada syndrome patient: Anesthetic consideration.

Brugada syndrome has a lethal arrhythmogenic risk during surgery or anesthesia. Perioperative drugs, electrolytic disturbances, and autonomic imbalance can trigger cardiac rhythm disturbances and even sudden cardiac death. Patients with this syndrome are at high risk during the perioperative period.

Optimal effect-site concentration of remifentanil for inhibiting response to laryngeal mask airway removal during emergence.

Purpose: This randomized, controlled, double-blind study was designed to determine the optimal dose of remifentanil for preventing complications associated with the removal of a laryngeal mask airway (LMA) without delaying emergence.

Materials And Methods: This study randomly assigned 128 patients to remifentanil effect-site concentrations (Ce) of 0 ng/mL (group R0), 0.5 ng/mL (group R0.
