The Impact of Inflammation and General Anesthesia on Memory and Executive Function in Mice.
Perioperative neurocognitive disorders (PNDs) are complex, multifactorial conditions that are associated with poor long-term outcomes. Inflammation and exposure to general anesthetic drugs are likely contributing factors; however, the relative impact of each factor alone versus the combination of these factors remains poorly understood. The goal of this study was to compare the relative impact of inflammation, general anesthesia, and the combination of both factors on memory and executive function. ⋯ Impairments in recognition memory were driven by inflammation. Deficits in executive function were only observed in mice cotreated with LPS and etomidate. Thus, an interplay between inflammation and etomidate anesthesia led to cognitive deficits that were not observed with either factor alone. These findings suggest that inflammation and anesthetic drugs may interact synergistically, or their combination may unmask covert or latent deficits induced by each factor alone, leading to PNDs.

Middle Ear Condition at the Time of Pediatric Myringotomy Tube Placement: Pain Associations Following Intraoperative Fentanyl/Ketorolac and Seasonal Variation.
Ketorolac-refractory pain behavior following bilateral myringotomy and pressure equalization tube placement (BMT) is associated with the absence of middle ear fluid. Intraoperative fentanyl/ketorolac affords more reliable pain control than ketorolac alone. We hypothesized that middle ear condition would correlate with postoperative pain despite such combination therapy. We further sought to demonstrate seasonal variation in ear condition and its influence on pain. ⋯ Normal/unilateral infected ears at time of pediatric BMT are associated with higher incidence of moderate-to-severe postoperative pain following intraoperative fentanyl/ketorolac administration, but the predictive value of ear condition on pain is limited. Infections were less common in the summer.

Observational StudyMortality and incidence of cardiovascular events in patients treated with aspirin and statins at one year after myocardial injury in noncardiac surgery: a prospective observational study.
Recommendations on the diagnosis and management of myocardial injury in noncardiac surgery (MINS) show remarkable variability. Mortality reports also vary. We aimed to describe mortality and major adverse cardiovascular and cerebrovascular event (MACCE) rates in patients with silent MINS treated with postoperative aspirin-statin therapy and with cardiology follow-up. ⋯ Rates of mortality and MACCE in patients with silent MINS were high despite aspirin-statin therapy and cardiology follow-up. Further prospective research is needed to assess new postoperative care protocols that might effectively improve outcomes.

Inherited and acquired coagulopathy are frequently associated with major bleeding in severe trauma, cardiac surgery with cardiopulmonary bypass, and postpartum hemorrhage. Perioperative management is multifactorial and includes preoperative optimization and discontinuation of anticoagulants and antiplatelet therapy in elective procedures. ⋯ Targeted goal-directed therapy using viscoelastic point-of-care monitoring is increasingly used to guide the administration of coagulation factors and allogenic blood products. In addition, damage control surgery, which includes tamponade of large wound areas, leaving surgical fields open, and other temporary maneuvers, should be considered when bleeding is refractory to hemostatic measures.
