Adult Multispecialty Anesthesia

The Division of Adult Multispecialty Anesthesia delivers outstanding evidence-based care, fosters innovation, and encourages individuals to pursue clinical and research interests.

We provide anesthesia care across a wide range of surgical specialties including ear, nose and throat (ENT), plastic surgery, orthopedic surgery, general surgery, neurosurgery, and vascular surgery. We also provide anesthesia services for a number of non-OR procedures, including those in interventional radiology, brachytherapy, interventional neuroradiology, gastroenterology, and interventional radiology.

Our wide-ranging research interests include both lab-based basic science research and active clinical research. The diverse areas of interest to which our faculty have contributed include: developing ERAS protocols for various services; innovative use of jet ventilation for solid organ ablations; and groundbreaking work on the use of convalescent plasma and vaccines during the COVID-19 pandemic.

Our faculty’s ongoing projects include researching mechanisms of anesthetic action in animal models, a trial site of the large multicenter CONSCIOUS 2 study and conducting a multidisciplinary study of antidepressant effects of psilocybin. In addition to our own projects, we help residents and medical students produce research to present at regional and national meetings and publish in a wide variety of journals.

Non-OR anesthesia (NORA)

Non-OR anesthesia (NORA) cases make up approximately 20 percent of total anesthesia cases at UW Health, or more than 8,000 cases per year. These cases include cardiac, radiologic imaging, CT ablation, interventional radiologic, neuroendovascular, stroke and gastroenterology procedures, as well as radiation therapy treatments. Overall NORA volumes have increased approximately 10 percent annually for nearly 10 years. We see no likelihood of this changing in the future.

Because we train future professionals to advance the practice of anesthesia, education is integral to our division. We teach a variety of learners about our specialty and demonstrate how our work integrates with the world of medicine. We train residents at most of UW Health’s clinical locations and expand our reach to alternative settings by providing educational opportunities in simulation for medical students, residents, and other learners.

Ambulatory Anesthesia

Ambulatory Anesthesia proudly provides comprehensive and compassionate care to an increasing number of patients in a variety of procedure and ambulatory surgery centers. We are able to effectively care for a wide spectrum of patients by adopting innovative approaches and the latest evidence-based anesthesia modalities. At Madison Surgery Center and Transformations Surgery Center, for example, we employ a host of general, regional and Monitored Anesthesia Care (MAC) anesthesia techniques for a variety of general, ophthalmology, orthopedic, otolaryngology, plastics, pediatric, urology and vascular surgeries performed. At Generations Fertility Center and the Digestive Health Center, we provide sedation services. We also provide coverage for UW Hospital Outpatient Surgery Center (OSC), where patients with more serious comorbidities are cared for on an outpatient basis.

Complementing our steadfast clinical mission, our division also offers a variety of educational opportunities. Beginning in their CA-1 year, residents are required to spend a four-week rotation in OSC. There, they are introduced to the challenges and nuances of ambulatory anesthesia. We also offer a senior ambulatory anesthesia elective for CA-3 residents who wish to operate in a more independent fashion. Finally, our division houses a unique ambulatory anesthesia and administrative medicine fellowship that offers insight into the business, financial, and administrative aspects of an anesthesiology practice.

Division Highlight

Dr. George Arndt has dedicated his career to advancing the practice of anesthesiology in airway management. His many innovations, including the Arndt Endobronchial Blocker and the Arndt Wire-Guided Airway Exchange Catheter, have improved the safety of anesthesia. Dr. Arndt’s immense impact extends to education. He has trained residents and medical students for more than three decades. His Arndt Airway Course, held annually for the last 20 years, helps learners of all disciplines advance their practice of airway management.
