Аннотация
BACKGROUND: Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is characterized by cardiac depression, respiratory failure, myopathy, and anesthesia for affected patients is challenging. Although several anesthetics have been safely employed, there are no reports on remimazolam used in those patients.
CASE PRESENTATION: A 47-year-old male with MELAS syndrome was diagnosed with mitral regurgitation and scheduled for transcatheter mitral valve repair under general anesthesia. Anesthesia was induced with remimazolam and remifentanil (0.3 µg/kg/min). Remimazolam was administered at 12 mg/kg/h until loss of consciousness for approximately 1 min. Anesthesia was maintained with 1.1-1.2 mg/kg/h of remimazolam and 0.1 µg/kg/min of remifentanil without circulatory collapse or severe metabolic acidosis. The tracheal tube was removed in the operating room.
CONCLUSION: Remimazolam may be a new option for anesthesia for MELAS syndrome patients with depressed heart function.
