Use of the modified Allen's test for screening before radial artery harvest may unnecessarily exclude some patients from use of this conduit and may also place a number of patients at risk for digit ischemia from such harvest. Direct digit pressure measurement is a simple, objective method that may more precisely select patients for radial artery harvest. Additional studies are needed to define objective digital pressure criteria that will accurately predict patients at risk for hand ischemia after radial harvest.

Simulation-based team training for staff caring for perioperative patients is associated with measurable improvements in teamwork and communication.

An elevated sP-selectin to IL-10 ratio appears to be associated with the development of VTE in patients at high risk and may prove to be a useful clinical marker for this dreaded complication among trauma patients. Early recognition of this high-risk group improves the accuracy of the risk/benefit determination for prophylaxis and identifies a group in whom routine ultrasound screening would be cost-effective.
