The frequency of gastroesophageal reflux when radiofrequency catheter ablation procedures for atrial fibrillation under general anesthesia with a supraglottic device

摘要

Radiofrequency catheterablation (RFCA) is performed in patients with drug refractory atrialfibrillation,and pulmonary vein isolation (PVI) is the main procedure. [1] DuringRFCA, sedation or generalanesthesiais required to relieve pain and discomfort. [2,3] RFCAunder generalanesthesia reduces therecurrencerate ofatrialfibrillation by enhancing catheter stability and mapping systemaccuracy compared to conscious sedation. [3,4] Asupraglottic device(SGD) is used instead oftrachealintubation to minimizethesympatheticresponse during generalanesthesiain patients with tachyarrhythmia. [5] However, the use ofa SGDduring generalanesthesia does not protect theairway and may causereflux of gastriccontents.
