Randomized Controlled Trial Clinical Trial
Is there postoperative evidence of implicit learning following aural stimuli at moderate hypnotic BIS levels during general anesthesia?
Patients may develop behavioral changes after the administration of a general anesthetic without a triggering stimulus. This phenomenon, referred to as implicit learning, continues to be debated. Some researchers have denied the phenomenon takes place, while others have demonstrated behavioral changes not related to recall. ⋯ A posttest was administered to determine explicit recall, as well as implicit memory formation. No patients had explicit recall. There was no difference in the implicit memory scores between patients in the experimental group and the control group.
