Case ReportsA Call for Real-Time Bispectral Index and Electroencephalogram Monitoring in a Patient Undergoing Aortic Surgery.
A 77-year-old woman underwent replacement of the ascending aorta and aortic valve. Before separation from cardiopulmonary bypass, the pump flow was reduced to 0-to-1.1 L/min/m2 for four minutes at a tympanic temperature of 34.3°C to perform additional sutureing for aorta-graft anastomosis. ⋯ An offline scalogram of intraoperative electroencephalograms obtained from the bispectral index monitor, which was generated by using continuous wavelet transform with complex Morlet wavelets, readily visualized the process of development of cerebral infarction preceding a significant decrease of regional cerebral oxygen saturation during the low-flow period of cardiopulmonary bypass. The present case demonstrated the possible importance of real-time bispectral index and electroencephalogram monitoring in patients undergoing cardiovascular surgery, especially those undergoing high-risk procedures under hypothermic circulatory arrest.

The Impact of Initial Postoperative Destination on Unplanned Critical Care Admissions After Lung Resection.
Despite an increasing proportion of patients undergoing lung resection being managed postoperatively in a ward-based environment, studies analyzing the impact of initial postoperative destination (IPD) on perioperative outcomes and unplanned critical care admission (UCCA) are lacking. ⋯ Most patients undergoing lung resection can be managed safely postoperatively in a ward-based environment. Short-term mortality is higher after UCCA, with patients who experience readmission to critical care at the highest risk of death. Patients should receive additional monitoring immediately following discharge from critical care.
