"In intensive care units, therapeutic paralysis has been a routine treatment method for many years in a select group of patients. Sufficient and appropriate sedation in patients undergoing therapeutic paralysis is crucial to prevent awareness and reduce the risk of excessive sedation. Both inadequate and excessive sedation levels can be highly detrimental to the patient. Clinical assessment may not always provide accurate information regarding sedation depth. Recently, the frequency and workload of therapeutic paralysis treatment in intensive care units have increased due to COVID-19 pneumonia. Therefore, the investigators believe that inadequate sedation may be common in these patients. Processed electroencephalogram parameters such as bispectral index or patient state index (PSI), routinely used in operating rooms and intensive care units, are commonly used to indicate sedation depth. In this study, the investigators aimed to determine sedation levels in patients during paralysis, assess the prevalence of inadequate or excessive sedation, and observe the doses of sedatives and analgesics used."
