Education and Regional Anesthesia
My principal clinical interest is the use of peripheral nerve blocks and the development of novel techniques to improve resident training. I have designed and launched a website (www.regionalABC.org) dedicated to lower extremity nerve blocks. This valuable resource is available to all clinicians in the operating room and in the pre-operative block area. It can be accessed by residents for learning and review whilst faculty can use the diagrams and clinical photographs to illustrate particular teaching points at the bedside. I am the co-director of the Carolina Cadaver Course, which is run annually in conjunction with Wake Forest University School of Medicine.
I am also actively involved in teaching the use of ultrasound for the placement of peripheral nerve blocks. I have lectured on several national courses.
Human Pharmacology Lab (HPL)
I am the Director of the HPL which is a Phase 1 research unit. The unit's members consist of clinical faculty with clinical interest across the spectrum of anesthesia. This year the HPL has completed the pharmacokinetic profile of a novel drug delivery device for inhaled fentanyl, which is currently under review by the FDA. We have started further volunteer and clinical studies of a new cerebral oximeter. The study group is about to embark upon a study to determine if dexmedetomidine confers the effect of restorative sleep upon postop surgical patients.
This faculty member (or a member of their immediate family) has a working relationship (i.e. consulting, research, and/or educational services) with the companies listed below. These relations have been reported to the health system leadership and, when appropriate, management plans are in place to address potential conflicts.
