Preoperative Transcranial Doppler as a Predictor for Delirium Following On-pump Cardiac Surgery

NCT02478736 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 175

No results posted yet for this study

Summary

Postoperative delirium is an important problem in patients undergoing major cardiac surgery and associated with more complicated hospital course, increased hospital length of stay and total postoperative cost. A study shows that a low preoperative cerebral oximetry (rSO2) is associated with postoperative delirium after on-pump cardiac surgery. Another study showed that patients who underwent cardiac surgery with reduced cerebral blood flow (CBF) velocity in the left middle cerebral artery (MCA) preoperatively are at greater risk for postoperative cognitive dysfunction (POCD). Therefore, the investigators hypothesize that lower perioperative rSO2 and reduced preoperative mean flow velocity (MFV) of MCA are good predictors of the postoperative delirium in the patients undergoing the on-pump cardiac surgery.
