Abstract

INTRODUCTION: The use of anesthetic substances to perform surgeries is indispensable, but remembering these events after the event is a serious complication. OBJECTIVES: To investigate the occurrence of intraoperative explicit memory in the current literature, to identify data relevant to the event and to correlate them. METHODS: A literary research was conducted, in which studies were searched in the database of Google Scholar, BvSalud, Pubmed, LILACs, Scielo from the keywords: Memory, intraoperative period, peroperative awareness, general anesthesia, memory, intraoperative period, intraoperative awareness, general anesthesia. Initially, 20,200 articles were found. Of these, literature reviews, doctoral theses, master's thesis were excluded, and a total of 18 articles were used, and these studies were published between 2019 and 2021. RESULTS: In the present study, there was an investigation whether anesthesia managed by residents can increase the incidence of consciousness in the self-reported intraoperative period compared to anesthesia managed by anesthesiatoses. Based on the raw data of the patients, the management of anesthesia by anesthesialists increased the incidence of consciousness compared to the management of anesthesia by residents. However, based on this analysis of the propensity score of the patient data, the management of anesthesia by anesthesiatoses did not increase the incidence of awareness. CONCLUSION: The investigation of the occurrence of intraoperative memory is performed by specialists and their research instruments, in this work assumption it was identified that the female gender, along with extremeages and anesthetic pre-procedures are causes of these memories in the surgical environment.
