Liver Fibrosis Marker and Postoperative Mortality in Patients Without Overt Liver Disease.
Nonalcoholic fatty liver disease (NAFLD) can progress to advanced fibrosis, which, in the nonsurgical population, is associated with poor hepatic and extrahepatic outcomes. Despite its high prevalence, NAFLD and related liver fibrosis may be overlooked during the preoperative evaluation, and the role of liver fibrosis as an independent risk factor for surgical-related mortality has yet to be tested. The aim of this study was to assess whether fibrosis-4 (FIB-4), which consists of age, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and platelets, a validated marker of liver fibrosis, is associated with postoperative mortality in the general surgical population. ⋯ A simple liver fibrosis marker is strongly associated with perioperative mortality in a population without apparent liver disease, and may aid in future surgical risk stratification and preoperative optimization.

Potentially Inappropriate Medication Administration Is Associated With Adverse Postoperative Outcomes in Older Surgical Patients: A Retrospective Cohort Study.
The American Geriatrics Society (AGS) Beers Criteria is an explicit list of potentially inappropriate medications (PIMs) best avoided in adults ≥65 years of age. Cognitively impaired and frail surgical patients often experience poor outcomes after surgery, but the impacts of PIMs on these patients are unclear. Our objective was to assess whether perioperative PIM administration was associated with poor outcomes in geriatric surgical patients. We then evaluated the association between PIM administration and postoperative outcomes in subgroups of patients who were frail or cognitively impaired. ⋯ Perioperative PIM administration was common in older surgical patients, including cognitively impaired and frail patients. PIM administration was associated with an increased hospital LOS, particularly in frail patients. There was no association found between PIM administration and discharge disposition.

BiographyThe Bupivacaine Story: A Tribute to George A. Albright, MD (1931-2020).
In 1979, George A. Albright, MD (1931-2020) published a controversial editorial in Anesthesiology that raised the question of bupivacaine cardiotoxicity. In it, he presented several cases of rapid cardiovascular collapse after administration of the highly lipophilic local anesthetic and called for further investigation. ⋯ In addition, Dr Albright's article led to the following changes: laboratory research that proved the cardiotoxicity of bupivacaine; the development of safer, stereoselective agents like ropivacaine; and the acceptance of lipid emulsion as a treatment for local anesthetic toxicity. In this article, C. Philip Larson, Jr, MDCM, Editor-in-Chief of Anesthesiology at the time of publication of Albright's manuscript, provides a unique perspective on the bupivacaine story.
