Early in his career, Dr. Hogue participated in multiple multicenter clinical investigations in the development of remifentanil and dexmedetomidine that eventually led to their approval for use in the Unites States. He also was an early investigator of the potential use of perfluorocarbon and free hemoglobin based blood substitutes.
More recently Dr. Hogue’s research has focused on neurological complications from cardiac surgery. He was the principle investigator on a National Institutes of Health sponsored clinical trial that investigated the potential role of perioperative estrogen replacement therapy as a means for providing neuroprotection for elderly women undergoing cardiac surgery.
Currently, Dr. Hogue and his colleagues are investigating methods to monitor cerebral blood flow autoregulation noninvasively and in real time.
Dr. Hogue and collaborators at England’s University of Cambridge have developed a method to monitor cerebral autoregulation noninvasively by using near-infrared spectroscopy (NIRS).
Two self-adhesive sensors are placed on the patient’s forehead and connected to an oximetry monitor. Clinical and laboratory research has shown that processing the collected NIRS signals serves as an acceptable surrogate for monitoring changes in cerebral blood flow.
Dr. Hogue and his colleagues believe that this approach can be used to optimize individual patients’ blood pressure to avoid loss of cerebral autoregulation—particularly during cardiac procedures such as cardiopulmonary bypass.
