Incidence and risk factors of early delirium after cardiac surgery.

Abstract

INTRODUCTION:

The aim of our study was to identify the incidence and risk factors of delirium after cardiac surgery implementing Intensive Care Delirium Screening Checklist (ICDSC).

MATERIAL AND METHODS:

87 patients, undergoing cardiac surgery at Vilnius University hospital, were prospectively monitored for postoperative delirium development, during intensive care unit stay.

RESULTS:

The incidence of postoperative delirium was 13.30%. No statistically relevant preoperative predictors of delirium were found. The duration of surgery was significantly longer in delirium group (4.51 ± 1.15 versus 3.76 ± 0.97 hours, P = 0.017). Patients in delirium group more often had blood product transfusions (1.50 (± 1.57) versus 0.49 (± 0.91) P = 0.003) and had a higher incidence of low cardiac output syndrome (33.30% versus 3.00%, P = 0.004); they were significantly longer mechanically ventilated (24.31 ± 28.35 versus 8.78 ± 4.77 (P < 0.001)) hours (OR = 1.15 (1.02-1.28)) and had twice longer ICU stay (5.00 ± 2.22 versus 2.60 ± 1.10 (P < 0.001)) days (OR = 1.91 (1.22-3.00)).

CONCLUSIONS:

The incidence of delirium after cardiac surgery was 13.3%. Independent predictors of delirium were duration of postoperative mechanical ventilation and intensive care unit stay.
