Comparative StudyThe Anesthesia Perioperative "Call for Help"-Experience at a Quaternary Pediatric Medical Center: Analysis of 67,564 Anesthesia Encounters.
During the past several decades, anesthesia has become increasingly safe. Truly major adverse events are rare, and anesthesia quality researchers have instituted programs to evaluate "near miss" or less critical adverse events to evaluate the safety of anesthesia delivery. In this study, we aimed to evaluate calls for emergency help in our institution as a surrogate for pending critical events. We hypothesized that calls would be more common in patients with high American Society of Anesthesiologists (ASA) physical status, history of prematurity, and children with recent respiratory illness compared to those without these characteristics. ⋯ Our study offers the most comprehensive analysis of emergent perioperative calls for help in pediatric anesthesia to date. We identified several characteristics, independently associated with more complicated and frequent perioperative STAT calls. Further research is required to evaluate the utility of this information in preventing and treating adverse events in children undergoing surgery and anesthesia.

Review Historical ArticleWhole Blood for Resuscitation in Adult Civilian Trauma in 2017: A Narrative Review.
After a hiatus of several decades, the concept of cold whole blood (WB) is being reintroduced into acute clinical trauma care in the United States. Initial implementation experience and data grew from military medical applications, followed by more recent development and data acquisition in civilian institutions. Anesthesiologists, especially those who work in acute trauma facilities, are likely to be presented with patients either receiving WB from the emergency department or may have WB as a therapeutic option in massive transfusion situations. ⋯ We summarize relevant recent retrospective military and preliminary civilian efficacy as well as safety data related to WB transfusion, and describe our experience with the initial implementation of WB transfusion at our level 1 trauma hospital. Suggestions and collective published experience from other centers as well as ours may be useful to those investigating such a program. The role of WB as a significant therapeutic option in civilian trauma awaits further prospective validation.

Complications Associated With Mortality in the National Surgical Quality Improvement Program Database.
Attributing causes of postoperative mortality is challenging, as death may be multifactorial. A better understanding of complications that occur in patients who die is important, as it allows clinicians to focus on the most impactful complications. We sought to determine the postoperative complications with the strongest independent association with 30-day mortality. ⋯ Additional resources should be focused on complications associated with the largest attributable mortality, such as respiratory failure and infections. This is particularly important for complications disproportionately impacting younger patients, given their longer life expectancy.

Review Historical ArticleFrozen in Time: A History of the Synthesis of Nitrous Oxide and How the Process Remained Unchanged for Over 2 Centuries.
Three major factors have contributed to the unrivaled popularity of nitrous oxide (N2O) among anesthetists in the 20th century and beyond: its impressive safety profile, its affordability, and its rapid induction and emergence times. These 3 characteristics of N2O have been discussed and written about extensively throughout the medical literature. Nonetheless, the characteristic that contributed most to N2O's initial discovery-the elegance and simplicity of its synthesis-has received substantially less attention. ⋯ In this article, we track the developments in the recognition and early synthesis of N2O, highlight the major players credited with its discovery, and examine its evolution from the late 1700s to today. The discovery and assimilation of N2O into common medical practice, alongside ether and chloroform, heralded a new paradigm in surgical medicine-one that no longer viewed pain as a fundamental component of surgical medicine. Its continued usage in modern medicine speaks to the brilliance and skill of the chemists and scientists involved in its initial discovery.

Misaligned Feeding May Aggravate Pain by Disruption of Sleep-Awake Rhythm.
Increasing evidence suggests that patients with eating disorders are more likely to develop chronic pain. A misaligned diet has been reported to disrupt the sleep-awake rhythms. Combined with our previous investigation on circadian pain, we aimed to investigate the role of misaligned diet in the pain sensitivity and the underlying mechanisms. ⋯ Misaligned diet might aggravate pain sensitivity through the disruption of the sleep-awake cycle, which could be recovered by Mel. NR2B-CaMKII-CREB may participate in the disruption of sleep-awake rhythm-mediated pain aggravation.
