Which anesthesia is kinder to your brain after spine surgery?

This study looked at how two common anesthesia drugs, sevoflurane and propofol, affect thinking and memory after spinal surgery. Twenty adults having spine surgery were randomly assigned to receive one of the two drugs. Their mental function was tested before surgery and again at 6 hours, 24 hours, 3 days, and 7 days after surgery using a simple questionnaire called the Mini-Mental State Examination (MMSE). The goal was to see if one drug causes less confusion or memory loss after surgery.
