ReviewA not so sweet scenario: impact of perioperative glucose control on regional anesthetic techniques for orthopedic surgery.
Diabetes and hyperglycemia are well established risk factors for complications associated with common orthopedic surgeries. In some practice settings, these conditions are also viewed as contraindications to regional nerve catheters. In this article, we aim to present our approach to offering the benefits of this modality in a safe manner for patients with diabetes and even some with preexisting, localized infections. ⋯ Based on our experience and reading of the literature, we advocate for a liberalized approach to use of continuous regional anesthesia for diabetic patients having for orthopedic surgery. A set of consensus guidelines tailored to institutions' resources and monitoring capabilities can be a useful tool for standardizing care. It may also increase access to the clinical benefits of this modality in a population particularly vulnerable to opioid related adverse effects.

ReviewEarly tracheostomy: on the cutting edge, some benefit more than others.
The decision to undergo early tracheostomy in critically ill patients has been the subject of multiple studies in recent years, including several meta-analyses and a large-scale examination of the National in-patient Sampling (NIS) database. The research has focused on different patient populations, and identified common outcomes measures related to ventilation. At the crux of the new research is the decision to undergo an additional invasive procedure, mainly tracheostomy, rather than attempt endotracheal tube ventilation with or without early extubation. Notably, recent research indicates that neurological and SARS-CoV-2 (COVID-19) patients seem to have an exaggerated benefit from early tracheostomy. ⋯ Specific populations such as neurosurgical and COVID-19 patients have clearly defined benefits following early tracheostomy. Although the benefit is less pronounced, there does seem to be an advantage in general ICU patients with regards to ventilator-free days and lower incidence of ventilator-associated pneumonia. In these patients, large-scale examination points to a clear mortality benefit.

The purpose of this review is to look at the current evidence on the consequences of intraoperative hypotension and discuss improvements that can be implemented for its prevention. ⋯ There should be a shift in paradigm in focusing on the prevention of intraoperative hypotension instead treatment. The suggested goals to help maintaining hemodynamic stability during anesthesia include ensure adequate blood pressure and flow; hypotension prevention; and ensure adequate anesthetic depth without overdose.

Although recent census demonstrates that women comprise 50.8% and ethnic minority groups collectively consist of 42.1% of the US population, the field of anesthesiology still demonstrates disparity in representation and health outcomes across race, ethnicity, and gender. In addition, the growing percentage of people that identify as lesbian, gay, bisexual, transgender, and queer (LGBTQ) compounded with limited representation among providers of their care can augment existing disparate outcomes within this community. ⋯ To achieve an optimized quality of healthcare, anesthesiologists and other providers should be a reflection of the communities they serve, including women, people of color, and LGBTQ. In this way, there is an increased likelihood of empathy, effective communication, and insightful perspectives on how to bridge the gap in health equity. A diverse lens is essential to ensure grassroots efforts lead to lasting transformational change.

Advances in the treatment of septic shock have historically focused on resuscitation endpoints, mainly mean arterial pressure and cardiac output. As the definitions of sepsis and septic shock have shifted to focus on the diversity of causes of dysregulated host-response we have seen an emerging phenotype where tissue hypoxia persists despite adequate macrocirculatory parameters. Interest in the topic of microcirculation is re-emerging as validated bedside techniques for hemodynamic monitoring, such as video microscopes, are becoming available. We review the current understanding of how sepsis induced hypoperfusion with a focus on recent advances in monitoring the microcirculation, and how a proliferation of biomarkers and emerging therapeutic targets may impact future research. ⋯ Sepsis is associated with changes in the microcirculation that can lead to tissue hypoxia and organ dysfunction. Further studies are needed to validate the usefulness of microcirculatory bedside tools in guiding resuscitative efforts.
