Observational StudyCharacterizing the Heart Rate Effects From Administration of Sugammadex to Reverse Neuromuscular Blockade: An Observational Study in Patients.
Reversal of neuromuscular blockade (NMB) with sugammadex can cause marked bradycardia and asystole. Administration of sugammadex typically occurs in a dynamic period when anesthetic adjuvants and gas concentrations are being titrated to achieve emergence. This evaluation examined the heart rate (HR) responses to sugammadex to reverse moderate to deep NMB during a steady-state period and sought mechanisms for HR changes. ⋯ Sugammadex to reverse moderate and deep NMB resulted in a fast onset and variable magnitude of HR slowing in patients. A difference in HR slowing as a function of dose did not achieve statistical significance. The observational nature of the investigation prevented a full understanding of the mechanism(s) of the HR slowing.

Pro-Con Debate: The Clinical (Ir)relevance of the Lower Limit of Cerebral Autoregulation for Anesthesiologists.
In this Pro-Con commentary article, we discuss whether the lower limit of cerebral autoregulation is clinically relevant for anesthesiologists. The central question regarding this issue is whether mean arterial blood pressure below the lower limit of autoregulation is detrimental for the brain. The Pro side argues that continuous monitoring of cerebral autoregulation has revealed an association between going below the lower limit and mortality in the critically ill patient. Conversely, the Con side argues that cerebral autoregulation is only one of various defense mechanisms of the brain that protect against cerebral hypoperfusion, and that cerebral autoregulation may be more important to protect against intracranial hypertension.

Postoperative cognitive dysfunction and delirium are undesirable consequences of surgery and anesthesia that regrettably do not have consistent predictive markers. Nor do they have reliable prophylactic or treatment methodologies. In an effort to better understand how anesthetic drugs alter the rate of postoperative delirium, Chang et al explore how patients with preoperative cognitive impairment respond to the influence of intraoperative ketamine. ⋯ Is it possible that ketamine and other drugs could be used as agents to stratify cognitive risk? Should we definitively avoid such drugs as potentiators of cognitive dysfunction? A variety of contextual limitations must be entertained when interpreting the results of this study as summarized in this infographic. These are also elaborated in greater detail in both the primary article as well as its attendant editorial. The reader is encouraged to review both in their entirety for an in-depth scope of understanding.

A Call to Action: A Specialty-Specific Course to Support the Next Generation of Clinician Scientists in Anesthesiology.
Clinical production pressure is a significant problem for faculty of anesthesiology departments who seek to remain involved in research. Lack of protected time to dedicate to research and insufficient external funding add to this long-standing issue. Recent trends in funding to the departments of anesthesiology and their academic output validate these concerns. ⋯ Directed toward early career academic anesthesiologists who wish to gain competency specifically in the fundamentals of clinical research and receive mentorship to develop an investigative project, the yearlong course will provide participants with the skills necessary to design research initiatives, ethically direct research teams, successfully communicate ideas with data analysts, and write and submit scientific articles. Additionally, the course, articulated in a series of interactive lectures, mentored activities, and workshops, will teach participants to review articles submitted for publication to medical journals and to critically appraise evidence in published research. It is our hope that this initiative will be of interest to junior faculty of academic anesthesiology departments nationally and internationally.

The provision of health services has been transforming from a largely top-down, paternalistic model into a construct in which patients play a substantive role in decision making over their care. Two articles in this month's issue of Anesthesia & Analgesia and an accompanying editorial address the growing momentum behind transparency in health care. Firstly, Quinonez et al consider the increasing expectation of family presence during surgical procedures and resuscitation of loved ones. ⋯ In conjunction with the increased desire for physical presence of loved ones during clinical procedures, so too is there a demand for complete access to all medical records, including even the arcane hieroglyphics of an anesthesia record as detailed by Ramaswamy et al. As federal law now mandates such access, questions naturally arise as to their utility and medicolegal implications. The reader is strongly encouraged to review the concepts elaborated in these articles for in depth appreciation of their considerations.
