Celebrating Ruby: 40 years of NAS→SNANSC→SNACC→SNACC.

The 40-year history of the Society of Neurosurgical Anesthesia and Critical Care (SNACC) is reviewed. Annual meetings have been a focus for reporting scientific advances and providing education to those attending. The society has undergone significant maturation dealing with transitions in leadership and dealing with an existential threat and undergoing name changes reflecting growth and maturation in its mission. SNACC has collaborated with several other professional societies, most notable being the American Society of Anesthesiologists (ASA), in which SNACC members have advocated for neuroscience in the ASA's educational and scientific activities, with several SNACC members being recognized through several major ASA awards and presentations. SNACC has been a strong advocate for educational advances, most recently addressing issues in neuroanesthesia fellowship accreditation and possibly certification. SNACC's initial North American focus has grown such that SNACC is now an international society dedicated to the advancement of neuroanesthesia, neurocritical care, neuromonitoring, and neuroscience.
