Preprocedural fasting policies for patients receiving tube feeding: A national survey.

Background: Patients who are critically ill frequently accrue substantial nutrition deficits due to multiple episodes of prolonged fasting prior to procedures. Existing literature suggests that, for most patients receiving tube feeding, the aspiration risk is low. Yet, national and international guidelines do not address fasting times for tube feeding, promoting uncertainty regarding optimal preprocedural fasting practice.

Outpatient Robotic surgery: Considerations for the Anesthesiologist.

A shortage of inpatient beds and nurses during the coronavirus disease 2019 pandemic has lent priority to safe same-day discharge after surgery. The minimally invasive nature of robotic surgery has allowed an increasing number of procedures to be done on an outpatient basis. Anesthetic management should be designed to complement the technical advantages of robotic surgery in facilitating early discharge.

Association Between Intraoperative Arterial Hypotension and Postoperative Delirium After Noncardiac Surgery: A Retrospective Multicenter Cohort Study.

Background: It is unclear whether intraoperative arterial hypotension is associated with postoperative delirium. We hypothesized that intraoperative hypotension within a range frequently observed in clinical practice is associated with increased odds of delirium after surgery.

Methods: Adult noncardiac surgical patients undergoing general anesthesia at 2 academic medical centers between 2005 and 2017 were included in this retrospective cohort study.

Effect of Intraoperative Arterial Hypotension on the Risk of Perioperative Stroke After Noncardiac Surgery: A Retrospective Multicenter Cohort Study.

Background: Intraoperative cerebral blood flow is mainly determined by cerebral perfusion pressure and cerebral autoregulation of vasomotor tone. About 1% of patients undergoing noncardiac surgery develop ischemic stroke. We hypothesized that intraoperative hypotension within a range frequently observed in clinical practice is associated with an increased risk of perioperative ischemic stroke within 7 days after surgery.

Clinical Research Redirection and Optimization During a Pandemic.

The COVID-19 pandemic has seen many hurdles to crucial research processes, in particular those that depend on personnel interactions, in providing safeguards against the incipient infectious disease. At the same time, there was a rapid redirection of research, driven by popular and social media and demand for pandemic-related content, to the detriment of non-COVID-19 research and perhaps to COVID-19 research itself. This article provides historical context to research redirection and discusses approaches to optimizing research methodology in the setting of COVID-19 pandemic.

New-Onset Atrial Fibrillation in Adult Patients After Cardiac Surgery.

Purpose Of Review: An overview of recent literature regarding pathophysiology, risk factors, prophylaxis, and treatment of new-onset atrial fibrillation (AF) in post-cardiac surgical patients.

Recent Findings: AF is the most frequent adverse event after cardiac surgery with significant associated morbidity, mortality, and financial cost. Its causes are multifactorial, and models to stratify patients into risk categories are progressing but a consistent, evidence-based system has not yet been developed.

Epicardial Cavernous Hemangioma: A Diagnostic Challenge.

• Primary cardiac tumors, although rare, represent a wide differential diagnosis. • It is often difficult to decipher the type of tumor from imaging alone. • This case highlights imaging modalities to plan surgical removal of cardiac masses.

NMDA Receptor Antagonists, Gabapentinoids, α-2 Agonists, and Dexamethasone and Other Non-Opioid Adjuvants: Do They Have a Role in Plastic Surgery?

Background: Inadequate pain control and opioid-related adverse effects result in delayed patient recovery and discharge times. Adjuvants help to improve the quality of analgesia and decrease opioid consumption, consequently decreasing opioid-related effects, such as nausea and vomiting, sedation, ileus, and respiratory depression. We review the mechanisms and clinical evidence for nonopioid adjuvants.
