TL;DR

  • A rare genetic variant (m.11232T>C) in mitochondrial DNA has been identified, affecting the mtND4 gene.
  • This mutation may increase cellular vulnerability to inhaled anesthetics, particularly sevoflurano.
  • Affected individuals can experience severe neurological complications, including permanent damage or death.
  • The condition is extremely rare, with sevoflurano successfully administered to over 1.2 billion people worldwide without similar incidents.
  • Most reported cases are linked to a direct maternal lineage from Carabobo, Venezuela.
  • Mitochondrial inheritance is exclusively maternal; patients with maternal ancestry from Carabobo or a history of anesthetic complications should inform their anesthesiologist.
  • Preventive measures include using total intravenous anesthesia (TIVA) instead of inhaled agents.
  • The Venezuelan Society of Anesthesiology is collaborating with national and international institutions on genomic studies.
  • International reports since 2021, particularly from Chile, and alerts from US anesthesiology societies in 2026 highlighted potential neurological damage in patients of Venezuelan maternal descent.
  • Anesthesiology societies recommend inquiring about Venezuelan maternal lineage and taking precautions, such as avoiding inhaled anesthetics.
