This study investigated intraoperative awareness among surgical patients exposed to Combined Intravenous and Inhaled Anaesthesia (CIIA) and Total Intravenous Anaesthesia (TIVA) in tertiary institutions in Ekiti State, Nigeria. The research employed a quantitative descriptive design, selecting 148 patients through consecutive sampling across three hospitals. Data collection utilized a modified Brice Interview and Michigan Awareness Classification instrument, evaluating patients’ awareness levels post-surgery. Results indicated that a significant proportion of patients reported no memory before or after anesthesia induction, with few experiencing dreams or negative perceptions related to their operation. Notably, 18.5% reported awareness during surgery, despite efforts to prevent it. Statistical analysis showed no significant difference in intraoperative awareness between CIIA and TIVA groups (p > 0.05). These findings align with existing literature, emphasizing the multifactorial nature of intraoperative awareness. Recommendations include implementing continuous monitoring techniques and enhancing anesthesia training to mitigate awareness risks and improve patient safety during surgeries.
