Anesthetic Effects on the Progression of Parkinson Disease in the Rat DJ-1 Model.
Parkinson disease is a chronic and progressive movement disorder characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The causes of Parkinson disease are not clear but may involve genetic susceptibilities and environmental factors. As in other neurodegenerative disorders, individuals predisposed to Parkinson disease may have an accelerated onset of symptoms following perioperative stress such as anesthesia, surgery, pain, and inflammation. We hypothesized that anesthesia alone accelerates the onset of Parkinson disease-like pathology and symptoms. ⋯ Multiple isoflurane exposures in this rat model of Parkinson disease transiently enhanced dopaminergic neurodegeneration in the SNpc that resolved over time and had no effects on progression in this Parkinson disease-like phenotype.

Practice GuidelineThe World Federation of Societies of Anaesthesiologists Minimum Capnometer Specifications 2021-A Guide for Health Care Decision Makers.
Capnometry, the measurement of respiratory carbon dioxide, is regarded as a highly recommended safety technology in intubated and nonintubated sedated and/or anesthetized patients. Its utility includes confirmation of initial and ongoing placement of an airway device as well as in detecting gas exchange, bronchospasm, airway obstruction, reduced cardiac output, and metabolic changes. The utility applies prehospital and throughout all phases of inhospital care. ⋯ The WFSA-Minimum Capnometer Specifications 2021 is based on the International Organization for Standardization (ISO) capnometer specifications. While industry is familiar with such specifications and their presentation format, most clinicians are not; therefore, this article serves to more clearly explain the requirements. In addition, the specifications as described can be used as a purchasing guide by clinicians.

Comparative Study Biography Historical ArticleThe First Cardiac Anesthesiology Fellow, William A. Lell: A Brief History.
Fifty years ago, on August 1, 1971, William A. Lell became the first cardiac anesthesia fellow at Harvard's Massachusetts General Hospital (MGH) Department of Anesthesiology, training with the world's first group of anesthesiologists whose clinical practice, teaching, and research efforts were exclusively devoted to cardiac anesthesia. ⋯ The challenges a young pioneer faced in establishing and maintaining an academic cardiac anesthesia program during the initial and rapid growth of an exciting new subspecialty are described. Dr Lell's experience emphasizes the importance of seizing new opportunities and establishing meaningful working relationships with colleagues based on mutual trust as fundamental to successful career development and research in a new medical subspecialty.
