Working in part from findings by a group in Boston about oxygen toxicity, Gregory - whose commitment to pediatric anesthesia is legendary - confirmed that oxygen toxicity was real and soon discovered that if you increased airway pressure with 30 percent oxygen, you could keep the airways open without harming the lungs. The result was Continuous Positive Airway Pressure (CPAP), which has saved the lives of countless children in respiratory distress.

SFGH opens new facility

In 1967, when Dick Barber arrived in San Francisco, the anesthesia faculty at San Francisco General Hospital (SFGH) consisted of just three members: Earnest P. Guy, Robert Hudson Smith, and himself. Operating rooms lacked piped gases and vacuum, relying on large cylinders of nitrous oxide and oxygen mounted on anesthesia machines. Despite the challenges, SFGH served as the city's sole level one trauma center, requiring round-the-clock coverage from anesthesia and surgical specialties. Over time, increased staffing, updated equipment, and city support culminated in the mid '70s with the opening of a new, state-of-the-art hospital. The new hospital facilitated Barber and his colleagues' ongoing crucial work for an underserved population.

Perioperative Thermoregulation - the importance of being normothermic

Dr. Daniel Sessler, starting from his residency at UCLA and continuing through his tenure at UCSF Anesthesia, conducted extensive research with his Outcomes Research Consortium. Their findings demonstrated that even slight hypothermia, common in unwarmed surgical patients, triples the risk of surgical wound infection, increases blood loss and transfusion needs, delays recovery, and prolongs hospital stays. It is now standard of care to keep surgical patients normothermic.

Beta blockade to reduce perioperative mortality

Researchers at the San Francisco Veterans Affairs Hospital, led by Dennis Mangano with Martin London and Art Wallace (dubbed McSPI), conducted an epidemiological study revealing poor surgical outcomes in older, sick patients. Seeking modifiable risk factors, they aimed to achieve hemodynamic stability without inducing unconsciousness. In a major clinical trial, they tested 17 drugs, including beta blockers, Alpha 2 agonists, and various anesthetic agents. In a landmark piece of research they published in the New England Journal of Medicine, McSPI found that the generic beta blocker atenolol was the most effective at reducing the risk of both myocardial ischemia and mortality. More than a hundred hospitals across the country adopted the McSPI protocols. Perioperative beta blockade in select patients became a level one standard of care.

UCSF-Led study suggests treatment combination that may increase chances for survival

In a study published May 22, 2023 in NEJM: Evidence, an international team of researchers from UCSF, Raymond Poincaré AP-HP Hospital, Versailles SQY University, Paris-Saclay University and Inserm, and the George Institute for Global Health in Sydney, studied the role of hydrocortisone in the management of adult patients with septic shock. They found that while the effect of hydrocortisone was modest in terms of overall survival, it was associated with a decrease in the need for blood pressure-raising drugs (vasopressors) and improvement in survival when used in combination with other corticosteroids. The study was coordinated by first authors Romain Pirracchio, MD, MPH, PhD, chief of Anesthesia at ZSFG and the Ronald D. Miller distinguished professor at UCSF, Djillali Annane, MD, PhD, and senior author Anthony Delaney, MBBS, MSc, PhD.

Originally published in 1981, Miller’s Anesthesia remains the definitive text on anesthesia practice. In the 10th edition expert editors and authors address timely topics alongside basic science for an in-depth and comprehensive understanding of the field.

The history of our department

1910

Prior to 1900, anesthesia was primarily supervised and taught by faculty surgeons at both didactic and clinical levels. Dr. Mary Elizabeth Botsford, after graduating from UC San Francisco in 1896, began her anesthesia practice in 1897, making her one of the first physician anesthesiologists in the nation. In 1910, she became the first faculty anesthetist at UCSF.

Botsford played a key role in professionalizing anesthesia. She established the first section on anesthesia in a state medical society and advocated for legislation to include anesthesia in medical school curricula. By 1930, she was the third president of the Associated Anesthetists of the US and Canada.

In the 1920s and 1930s, hospital-employed physicians provided anesthesia as a service. Botsford led anesthesia services within the Department of Surgery, which had five women physicians by 1921. By 1925, Drs. Mary Botsford, Ethel Righetti, Mary Kavanagh, and Dorothy Wood were integral to providing anesthesia at UCSF.

Botsford was a dynamic teacher, offering lectures, demonstrations, and electives in anesthesia to medical students. Though no official anesthesia residencies existed, informal teaching was ongoing. During this period, Dr. Chauncey Leake conducted pioneering research on anesthetic agents in the Department of Pharmacology.

1932

In 1932, Botsford was appointed clinical professor of anesthesiology, UC's first professor of anesthesia.

1941

In 1941, a Division of Anesthesia was established within the Department of Surgery, coinciding with the launch of a formal residency program. Initially, the faculty comprised 4 members overseeing 10 residency positions. The department primarily focused on providing anesthesia for surgeries, with occasional consultations for intensive care and obstetric cases. Research was limited, and recruitment of residents was challenging due to World War II.

1957

On September 4, 1957, Julius Comroe arrived in Iowa City for a meeting of the American Physiologic Society. Comroe, the newly appointed director of UCSF’s planned Cardiovascular Research Institute (CVRI), was also focused on enhancing UCSF’s reputation and establishing the CVRI as a key resource for researchers. He believed the emerging field of anesthesia could contribute significantly to this goal.

Comroe met with Stuart Cullen, who had built an impressive academic department at Iowa. By the end of their meeting, Comroe asked Cullen to lead anesthesia at UCSF. Cullen was intrigued but insisted that anesthesia must have its own department, separate from surgery, before he would agree to join.

1958

Within hours, Comroe convinced UCSF to establish an independent Department of Anesthesia. In 1958, Dr. Stuart C. Cullen became its first chairman. Cullen recruited John Severinghaus, and together with faculty members Neri Guadagni, Frank DeBon, Earnest Guy (chief of anesthesia at San Francisco General Hospital), and new resident Walter "Skip" Way, they formed the core team.

Over the next 60+ years, the department played a pivotal role in the growth of modern anesthesia, significantly impacting surgical practice, critical care, and pain management. The department quickly gained a reputation for excellence in research, education, and clinical care, matching or surpassing any institution worldwide.

Dr. Cullen and his faculty expanded the residency program to include obstetric anesthesia, ICU, and training at San Francisco General Hospital. They also developed undergraduate teaching and a productive research unit. In June 1966, Cullen left the chairmanship to become Dean of the School of Medicine, during which time the department earned an international reputation for its research.

1967

Dr. William K. Hamilton (1922-2017) became chairman in 1967, continuing the department's growth. An anesthesia unit was established at the Veterans Administration Hospital, and the department took over the ICU at San Francisco General Hospital. Faculty began providing care in the pediatric and newborn ICUs at University Hospital, and the research base was significantly expanded in quality and depth. 

1983

In 1983, Dr. Hamilton became vice dean and associate dean for Postdoctoral and Clinical Affairs. In 1984, as the department celebrated its 25th anniversary, Dr. Ronald D. Miller succeeded him as chair. The first edition of the “Miller’s Anesthesia” textbook was published in 1981, and now in its 10th edition, is a global standard.

Under Dr. Miller, the department expanded its clinical responsibilities, including preoperative evaluation, operating room, recovery, and critical care. It launched a model outpatient pain management program and assumed leadership roles at all UCSF-affiliated facilities.

The department became one of the largest and most prestigious academic anesthesia programs globally, pioneering simulation-based learning and flexible residencies in research and critical care. Dr. Miller foresaw the importance of molecular biology in medical research, modernizing the department's research program. The department has consistently been a top recipient of NIH funding.

2009

After leading the department through its 50th birthday celebration, Dr. Ronald D. Miller stepped down as chair. Dr. Mervyn Maze succeeded him, renowned for his pioneering studies on general anesthetics, notably co-inventing dexmedetomidine, widely used for sedation in perioperative and critical care. His innovative research earned him awards like the American Society of Anesthesiology's Excellence in Research award.

2015

Dr. Michael Gropper succeeded Dr. Maze in 2015, transitioning from his roles as chief of Critical Care Medicine at UCSF and as acting and interim chair. The Department of Anesthesia and Perioperative Care now boasts over 250 faculty members, 82 clinical residents, and over 20 research trainees and fellows. Active units are spread across various medical centers, including Zuckerberg San Francisco General Hospital, San Francisco Veterans Affairs Medical Center, Mount Zion Medical Center, UCSF Orthopaedic Institute, and several specialty hospitals in the Mission Bay neighborhood. Beyond operating rooms, the department plays crucial roles in ambulatory care, pain management, critical care, and preoperative evaluation.

Faculty members continue to influence the field nationally and internationally, participating in NIH study sections, securing funding, and serving on FDA and editorial boards. Graduates of the program hold prominent positions in academia and private practice, with many assuming leadership roles in hospitals and professional organizations. The department's contributions have shaped the evolution of anesthesiology since its establishment in 1958, with several faculty members recognized for innovative research.
