PostOperative Delirium (POD) is the most common neuropsychiatric complication following cardiac surgery and may be related to morphine consumption. PostOperative Delirium (POD) prolongs hospital and intensive care unit (ICU) length of stay (LOS) and increases morbidity and mortality. No study has been conducted to demonstrate the effect of regional anesthesia using catheters inserted before sternotomy.

This study investigate the effect of an enhanced recovery protocol using regional anesthesia on PostOperative Delirium (POD) onset.
