Dr. Frederick E. Sieber is a professor of anesthesiology and critical care medicine at the Johns Hopkins University School of Medicine. He serves as chair and director of Clinical Research of the Department of Anesthesiology and Critical Care Medicine.
Dr. Sieber received a B.A. in chemistry from Northwestern University and an M.D. from the University of Pittsburgh. He completed a medical internship at the Pennsylvania Hospital in Philadelphia. After a residency in anesthesiology and a fellowship in neuroanesthesiology at the University of Pennsylvania, he joined the Johns Hopkins faculty in 1985.
His research interests focus on problems specific to geriatric surgical patients and on optimization of their surgical outcomes. Through multidisciplinary clinical research, he studies elderly surgical patients, especially those undergoing orthopaedic procedures.
Dr. Sieber is a member of the American Society of Anesthesiologists, the International Anesthesia Research Society, the Association of University Anesthesiologists and the Society for Advancement of Geriatric Anesthesia. He serves as president-elect of the Society for Advancement of Geriatric Anesthesia and is a member of that organization’s Committee on Geriatric Anesthesia. He is board certified in anesthesiology and critical care medicine.

Research & Publications
Dr. Sieber’s research focuses on problems specific to geriatric surgical patients and on optimization of their surgical outcomes. Through multidisciplinary clinical research, he studies elderly surgical patients, especially those undergoing orthopedic procedures.
At Johns Hopkins Bayview Medical Center, a multidisciplinary Hip Fracture Service has been ongoing since the late 1990s. The service includes Anesthesiology (Dr. Sieber and Mary-Rita Blute, RN, MS), Orthopaedics (Drs. Simon Mears and Tariq Nayfeh), Geriatrics (Dr. Jeremy Walston), and Neuropsychiatry (Drs. Constantine Lyketsos, Benjamin Lee, and Paul Rosenberg). Several members of the Hip Fracture Service have funded clinical research projects. Dr. Mears, for example, has a grant from the Orthopaedic Trauma Association to study inflammatory markers of delirium in elderly surgical patients who have had a repair of a traumatic hip fracture or who have had an elective hip replacement. Dr. Mears and the Anesthesiology team collect perioperative cerebrospinal fluid and blood samples from these patients to measure inflammatory and dementia markers and their possible relationships to postoperative delirium.
Second, an NIH-funded multi-center trial is investigating whether the sedative dexmedetomidine attenuates postoperative delirium and cognitive dysfunction in elderly surgical patients. Dr. Sieber is Johns Hopkins’ principal investigator for this trial.
Third, in another NIH-funded clinical trial, Dr. Sieber and his team are researching the effects of depth of sedation (as measured by the BIS monitor and the OAA/S score) during regional anesthesia with propofol on the incidence of postoperative delirium, cognitive dysfunction and mortality in elderly hip fracture patients.
