Critical Care
The Critical Care Division in the UNMC Department of Anesthesiology educates the next generation of critical care leaders in a supportive and nurturing environment. Through UNMC's clinical partners, the division delivers state-of-the-art care to critically ill patients from across the region.
Research includes large outcomes studies, multi-center randomized controlled trials, and translational research. Research mentorship for fellows and junior faculty is provided by senior faculty, including the department chair and the vice chair for research, both of whom are members of the Critical Care Division.
Our faculty members work through UNMC's clinical partners to provide collaborative, comprehensive care for a wide variety of patients – including from cardiothoracic, vascular, cardiology, ECMO, surgical oncology, obstetric, otolaryngology and other services.
Many members of our division serve in national leadership positions, as well as in leadership within UNMC's primary clinical partner, Nebraska Medicine.
Our division has a long history of providing critical care and leadership within the internationally known Nebraska Biocontainment Unit. Through the biocontainment unit, physicians in our division provided direct care for Ebola patients in 2014 and for COVID patients in 2020.

Critical Care Anesthesiology Fellowship
The Critical Care Anesthesiology Fellowship provides training and mentorship to future critical care anesthesiologists to allow them to excel clinically and become leaders in education and research. Get details about the program and meet our current fellows.
