Anesthesiology
-
An interesting exploration of the surgeon-anesthesiologist relationship, framed in terms of it being the critical dyad of the operating theatre team.
Cooper explores the positives and negatives, the stereotypes that each craftgroup holds of the other, and the ways in which these translate to team performance.
Most significantly, Cooper makes the point that when highly functional this relationship can lead to the highest quality patient care, but at its worst, dysfunction can lead to extreme harm and compromise patient safety.

Observational Study
Cognitive Decline after Delirium in Patients Undergoing Cardiac Surgery.
Cardiac surgery is associated with cognitive decline and postoperative delirium. The relationship between postoperative delirium and cognitive decline after cardiac surgery is unclear ⋯ Patients who developed delirium had greater decline in a composite measure of cognition and in visuoconstruction and processing speed domains at 1 month. The differences in cognitive change by delirium were not significant at 1 yr, with the exception of processing speed.

Processed Electroencephalogram Monitoring and Postoperative Delirium: A Systematic Review and Meta-analysis.
Use of processed-EEG monitoring to guide anaesthesia depth is associated with a 38% odds reduction of developing postoperative delirium.

Observational Study
Defining an Intraoperative Hypotension Threshold in Association with Stroke in Cardiac Surgery.
WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Stroke is a leading cause of morbidity, mortality, and disability in patients undergoing cardiac surgery. Identifying modifiable perioperative stroke risk factors may lead to improved patient outcomes. The association between the severity and duration of intraoperative hypotension and postoperative stroke in patients undergoing cardiac surgery was evaluated. ⋯ Hypotension is a potentially modifiable risk factor for perioperative stroke. The study's findings suggest that mean arterial pressure may be an important intraoperative therapeutic hemodynamic target to reduce the incidence of stroke in patients undergoing cardiopulmonary bypass.
