Ability of Glasgow Coma Scale and Full Outline of Unresponsiveness Score in Measuring Level of Consciousness and Outcome in Patients Receiving Sedation Under Mechanical Ventilation

Background: Determining the level of consciousness is one of the main responsibilities of nurses in intensive care unit (ICUs). Scales used to determine the level of consciousness should be less affected by the injection of analgesics and sedatives and should provide proper vision of the patient’s status. Objectives: This study was conducted to assess the ability of two tools including Glasgow coma scale (GCS) and full outline of unresponsiveness (FOUR) score in measuring the level of consciousness and outcome in patients receiving sedation under mechanical
