This episode breaks down the underlying mitochondrial mechanism, why TIVA with propofol is the safer anesthetic strategy, and the family history red flags every provider should be screening for. A newly identified genetic mutation that turns routine sevoflurane exposure into catastrophic, permanent neurological injury The mitochondrial mechanism behind it, and why some patients have zero reserve capacity to absorb the hit Why TIVA with propofol becomes the clear anesthetic choice once you understand what spares Complex I Source : Sanz-Pons J, et al.
