Clinical and Research Interests
I am a pediatric critical care scientist, a translational researcher who simulates complications from biomedical devices in the laboratory in order to develop improved diagnostic or therapeutic modalities for critically ill children. My current emphasis is to focus on the pathophysiological basis of the untoward effects of cardiopulmonary bypass (CPB) devices on blood components in critically ill children. Over 18,000 children are supported each year by CPB devices which has led to a significant decline in the mortality and morbidity of children suffering from life threatening heart or lung diseases. However, complications from these devices such as bleeding, stroke, and inflammatory response remain poorly controlled.

Specifically, we are studying microparticles, submicron vesicles released from cells when under a state of activation from agonists, shear-stress, or apoptosis. Recent research has shown them to be a strong promoter and mediator of strokes or inflammatory response. We are exploring if biomedical devices are a potent activators of these microparticles and the relative microparticle pathophysiology, therapeutic, and diagnostic applications in pediatrics.

If treatments could then be devised to decrease the rate of complications from CPB then the number of patients who could benefit from this technology may increase. Studies from the H1N1 epidemic demonstrated that transport to an extracorporeal membrane oxygenation (ECMO) referral center, ECMO is miniature CPB outside the operating room, reduced mortality by 50% when compared to patients who were not referred for ECMO support. With expansion of this technology we could decrease the mortality and morbidity of all children suffering from cardiac or respiratory failure, not just patients needing CPB surgery.

Interests:
Pediatric Cardiac Intensive Care - I am one of four pediatric critical care faculty members who specialize in the care of the post-operative pediatric patient with congenital heart disease. This area of pediatric intensive care requires specialized care due to the unusual anatomy and physiology of these patients. Also, many of these patients require several operations to repair their heart disease and the continuity of care provided by a dedicated team of physicians is very important. Physicians referring patients for repair of congenital heart disease often prefer to send their patients to a program with a dedicated intensive care unit team. The cardiac surgeons and cardiologists we work with also benefit from the specialized team. They know each cardiac intensive care physician well and we have developed a very good working relationship with them.

Transport Medicine - Since becoming the medical director of the pediatric transport team and Christus Santa Rosa Children‘s Hospital I have obtained specialized training in transport medicine. I have attended conferences arranged by organizations such as the Air Medical Physicians Association and The American Academy of Pediatrics Section on Transport Medicine. Through these meetings I have obtained specialized knowledge pertaining to transport medicine including the effects of altitude on the critically ill patient, transport safety issues related to ground versus air transport, organizing and maintaining an efficient and competent transport service, outreach strategies and the development of interhospital communication and relations. I have used this specialized knowledge to educate the nurses, respiratory therapists, students, residents, fellows, and my colleagues.
