The Incidence of Awareness During Surgery And Affecting Factors in Patients Who Undergo General Anesthesia in Besat Hospital in Hamadan- 2016

Awareness during anesthesia is a side effect associated with general anesthesia and refers to a condition in which brain awakens by a stimulus during a period of general anesthesia. The experiences are stored in explicit memory and patient might recall a few things after recovering from anesthesia. The experiences are sometimes in the form of pain perception, but the patient is not able to show a reaction due to the administration of muscle relaxants, the feeling of weakness and helplessness caused by intraoperative awareness might cause some patients to develop lasting and significant psychological issues. Given the importance of monitoring and maintaining the depth of anesthesia, this study aimed to determine the incidence of awareness and recall during general anesthesia.

A total of 400 patients who were referred to Besat Hospital and underwent various surgical procedures in 2016 were involved in this study. Data collection was performed using a questionnaire previously utilized by other researchers to study the same topic. Patients were visited 24 to 36 hours after recovery and interviewed about their experiences before, after and during operation. The data collected from each patient were then recorded in the patients questionnaire form.

data were obtained from patients indicates that out of 400 patients, 249 patients were men (62.3%) and 151 patients were women (37.7%). In order to induce, propofol was used in 71.8%, thiopental sodium in 27.3% and ketamine in 0.9% of patients. Benzodiazepines were used as 1 . نویسنده مسوول: dsmbszolhavarieh@gmail.com 53 preanesthetic agents in 87.8% of cases. Ten patients (2.5%) had pointed to issues that suggested consciousness during anesthesia. The only significant connection in this study was found to be the lack of use of benzodiazepines and awakening during anesthesia.

Given the increased risk of awakening during anesthesia without use of benzodiazepines as preanesthetic drugs, we suggest administration of these agents as far as possible in general anesthetics. Also, our findings indicate that the prevalence of consciousness during anesthesia is higher in our country compared to other countries.
