ABSTRACT

Introduction: We made a prospective, exploratory and blind study to evaluate the incidence of memory during general balanced anesthesia. Whereas implicit memory as the information retained in the memory that is not accompanied by conscious recollection. And explicit memory information that is consciously recollected. Objective: The aim of this study was to determinate the incidence of implicit and explicit memory in a group of patients during general balanced anesthesia in open surgery cholecystectomy in General Hospital of Mexico. Material and methods: We studied 31 ASA I-II patients during general balanced anesthesia. No one received pre-anesthetic medication. Fentanyl citrate and thiopental induction was made, Vecuronium bromure was used for neuromuscular relaxation, and they were supported with 02 100% and isoflurane. During the procedure we measured heart rate and blood pressure all time. When peritoneum incision was made each patient was placed with headphones and they listened a short narration tape with a children’s story. After surgery when patient was recovered from the anesthetic residues, we evaluated implicit memory and explicit memory. Results: We found 30 patients whom had a negative answer to all questions related to explicit memory and only one patient was able to answered to implicit memory evaluation. Conclusions: Incidence of implicit memory was found 3.2% in study sample population. Upper cerebral functions have to be evaluated in all patients who is going to be in general anesthesia procedures; if we do it, we could decrease patient’s memory, recall and awareness incidence.
