Researchers Seek to Personalize Blood Pressure Maintenance During Surgery

The complexity and acuity of patients undergoing cardiac surgery can leave them vulnerable to surgical complications. Unfortunately these complications can include stroke, cognitive changes and memory loss, and can have devastating impacts on patients and their families. The Cardiac Anesthesia Division at Johns Hopkins is highly engaged in clinical research to help reduce patient risk of these complications, particularly in the taking steps to ensure appropriate oxygen delivery to the brain during surgery.

Each patient has a unique range of pressures for which their brain blood vessels can work to maintain adequate blood flow. The researches in the Cardiac Anesthesia Division are investigating how to accurately measure blood pressure, brain blood flow, and oxygen in order to determine the optimal blood pressure for each patient undergoing cardiac surgery. This groundbreaking work has the potential to decrease the likelihood of neurological complications by personalizing blood pressure management during surgery.
