Clinical Interests:
General, vascular, high-risk, ambulatory, and liver-transplantation anesthesiology; acute pain
Research Interests:
My current research interests include postoperative nausea and vomiting (PONV), acute postoperative pain, clinical pharmacology of anesthetic drugs and resuscitation fluids as well as database research in postoperative outcomes.
Improving Outcome in Surgical Patients:
Nausea and vomiting is regarded as one of the most unpleasant experiences in postoperative recovery. To date, there is no single antiemetic which can satisfactorily control PONV. My interests concentrate on the use of new and novel antiemetics, combination antiemetic therapy, as well as new methods of delivery of these medications.
Another research interest is fluid resuscitation during surgery. I have conducted a number of studies investigating the intraoperative use of a new balanced colloid. I am investigating the use of esophageal Doppler, a relatively non-invasive cardiac output monitor, as a guide for fluid loading during major blood-loss surgery.
Improving Quality of Recovery in Geriatric Patients:
My previous experience with bispectral index monitoring has aroused my interest to pursue other clinical investigations in this area. With the International Anesthetic Research Society Clinical Scholar Award, I am investigating the recovery of elderly patients from day surgery with the use of bispectral index.
Much of what we do in anesthesia may not effect mortality and influence the length of hospital stay. However, the quality of recovery, such as the avoidance of pain and absence of postoperative nausea and vomiting can be prevented. In these days of cost containment in healthcare, managed care companies may not be interested in additional expenses that do not have an impact on the duration of hospital stay. With new methodology, I am assessing patients willingness to pay to avoid these postoperative discomforts.
