Delayed seizures following sedation with propofol

Abstract

Seizures occurred in two adolescents approximately six hours after sedation with propofol for bone marrow biopsy. Case #1 was a patient with chronic renal failure, hypertension, and anaemia. Case #2 had just been diagnosed with acute lymphocytic leukaemia. Neither child had experienced seizures before, and both recovered without neurological sequelae. Although other factors may have caused the seizures, the episodes have raised concerns about the safety of propofol for patients travelling home after outpatient surgery. Further study is required to explain the cause of this complication or, at least, to identify risk factors. © 1993 Canadian Anesthesiologists.
