Question: Post-surgical psychosis

 mkjd1986 - Thu Jan 08, 2009 3:54 pm

I awoke from back surgery (fusion L5-S1) in state of psychosis. Eventually the psychosis cleared, but continues to be a problem when I am under stress or take certain medications. Could the general anesthesia have caused this and how does post-surgical brain damage usually present?

User avatar Hello --

While post-surgical psychosis most often is seen as "ICU psychosis", I would guess you didn't spend much, if any, time in ICU following your surgery. Still, this happens fairly frequently. It is believed the causes vary, overlap, and are generally common in recovery and ICU units. Certainly general anesthesia can play a role in it and probably can sometimes be the sole cause. Also, various other medications, electrolyte imbalances, disorientation of sensory deprivation, etc., can, in varying combinations, cause this response, as well as idiosyncratic response to trauma of surgery by the bodies of certain subjects.

None of this directly answers your question, but hopefully it helps put the problem into a more useful context. You didn't describe the symptoms of your particular psychotic experience, and that would be helpful; hallucinations are probably most common, along with time/space disorientation and the recollection of factitious events. Anxiety, paranoia, etc., are also often seen. As a rule the problem will resolve with time. If, however, there was actual organic damage or change to the brain, this could cause recurrent episodes or at least increased sensitivity to certain drugs (especially antihistimines, and most especially Diphenhydramine, brand name Benadryl).

There is also the possibility that a lesion existed prior to the surgery and this merely opened the door for the symptoms to emerge.

If you could elaborate on the symptoms it might be helpful. If you haven't already, you would probably benefit from a neurological evaluation with possible psych consult as well.

Hope this is helpful. Best of luck to you. Please follow up with us as needed.
