Perioperative management for chronic schizophrenic patients.

Schizophrenic patients are at increased risk for perioperative complications, as their biological response to stress is impaired. The increased complications are associated with physical disorders, antipsychotic or hazardous health behaviors, and interactions between antipsychotics and anesthetic drugs. Thus, anesthesiologists must not only be aware of the perioperative problems of these patients but must also learn how to manage their perioperative course.
