Brief Summary

There are limited studies in the literature investigating the relationship between delirium and the pre- and post-extubation periods in patients planned for extubation. Determining the impact of existing delirium during the extubation process or the possible causes of delirium occurring in this period may contribute to early recognition, prevention, or treatment of delirium. In our study, we screened patients scheduled for extubation in the intensive care unit using the Confusion Assessment Method for the ICU (CAM-ICU) before extubation and during the 48-hour post-extubation period to investigate the type of delirium, its relationship with sedation, and possible triggering and risk factors.

Methods: The study was conducted with 38 patients over 18 years old who had been on mechanical ventilation (MV) for at least 24 hours and had Richmond Agitation and Sedation Scale (RASS) scores between +4 and -3. CAM-ICU was applied to patients before extubation, and then the patients were weaned from mechanical ventilation. Age, sex, APACHE-II, SOFA, mCCI scores, length of stay, and duration of intubation were compared between CAM-ICU negative and positive patients before extubation, and the relationship with sedation type was evaluated. CAM-ICU was also applied at 24 and 48 hours after extubation, and the results were compared with arterial blood gas parameters including PaO2/FiO2, PCO2, and lactate levels.
