Core Tip

Core Tip: The R-on-T phenomenon is associated with an increased risk of fatal arrhythmia. It may initiate ventricular tachycardia and ventricular fibrillation, and its appearance seem to be associated with a poor prognosis. However, this phenomenon is rarely encountered in the preoperative inpatient setting. The anesthetic management of patients with this particular manifestation poses a great challenge. We herein describe a patient who was scheduled for laparoscopic-assisted sigmoid colon resection when the R-on-T phenomenon was incidentally discovered. Our experience suggests that the anesthetic process can be greatly optimized by detailed preoperative assessment and preparation with interdisciplinary cooperation.
