Assessment of Correlation Between Brain Function Index and Three Common Sedation Scales in Intensive Care Unit Patients

Background: This study aimed to evaluate the correlation of brain function index (BFI) with three criteria consciousness (Glasgow, Richmond, and FOUR score) in intensive care unit. Methods: We enrolled patients aged over 15 years who required no muscle relaxants had hearing visual impairment, mental retardation, disorder, hemodynamic instability (MAP < 60 mmHg), hypoxia (SpO2 90%), as well electrical activity disorders such epilepsy focal disease, those not undergone anesthesia surgery for past 24 hours. Results: All ICU were autumn winter based on inclusion exclusion (n = 85). During hours, BFI clinical sedation including RASS, GCS, score assessed times a minimum four-hour intervals. Among patients, 45 (52.9%) males, 40 (47.1%) females; (28.2%) under age, 13 (15.3%) between 41 old, 48 (56.5%) 61 old. There was significant positive relationship patient score, GCS. The higher than other two criteria. Conclusions: Objective assessing level are sufficiently accurate can be used instead assess special wards.
