Seizures & liposuction: Can anesthesia bring on an episode?

This is a fantastic question! Overall, inhaled (gaseous) and IV anesthetic agents have anticonvulsant properties and actually raise the seizure threshold by causing generalized central nervous system (brain) activity depression. Therefore, in general, anesthesia should not cause seizure activity in patients prone to this. However, there are rare instances where anesthetics can cause seizures - I actually experienced this myself during a minor surgical procedure I underwent years ago. It is therefore incredibly important to discuss your concerns with a board certified plastic surgeon as well as an anesthesiologist to ensure that any elective procedures you decide to undergo will be first and foremost safe. 

While the stress of surgery could possibly trigger seizure activity, the medications you would be receiving for a general anesthetic (likely midazolam and propofal) will sedate the central nervous system to reduce this risk.  Ask to speak with the anesthesiologist before the day of surgery.
