The Evolving Landscape of Perioperative Medicine

The concept of perioperative evaluation and optimization has evolved over the recent decades as a multifaceted, multidisciplinary paradigm, which consolidates the medical science, information technology, and social, fiscal, and legal aspects into a unified process. The comprehensive assessment of the health status of the patients aims to identify medical conditions that can affect procedural and anesthetic complications, and, through their optimization, to reduce morbidity and mortality, increase patient satisfaction, and control the perioperative socioeconomic burdens.

What’s New in Preoperative Cardiac Testing

More than 300 million surgeries are performed annually worldwide. Patients are progressively aging and often have multiple comorbidities that put them at increased cardiovascular risk in the perioperative period. The United States published latest guidelines regarding preoperative cardiac evaluation and risk stratification for patients undergoing non-cardiac surgery in 2014. There are multiple risk stratification tools available that can help guide management. Furthermore, newer laboratory tests, such as preoperative NT-proBNP and high-sensitivity troponin assays, may aid in preventing and diagnosing perioperative myocardial injury.

Perioperative Management of Novel Pharmacotherapies for Heart Failure and Pulmonary Hypertension

Heart failure (HF) and pulmonary hypertension (PH) are increasingly prevalent comorbidities in patients presenting for noncardiac surgery. The unique pathophysiology and pharmacotherapies associated with these syndromes have important perioperative implications. As new medications for HF and PH emerge, it is imperative that anesthesiologists and other perioperative providers understand their mechanisms of action, pharmacokinetics, and potential adverse effects. We present an overview of the novel HF and PH pharmacotherapies and strategies for their perioperative management.

Management of Preoperative Anemia

Anemia is the most common modifiable risk factor for postoperative morbidity and mortality. Early identification and optimal management are key to restore iron stores and ensure its resolution before surgery. Several therapies have been proposed to treat anemia in the perioperative period, such as iron supplementation and erythropoiesis-stimulating agents, though it remains unclear which is the most optimal to improve clinical outcomes. This article summarizes the most updated evidence on perioperative management of anemia and denotes differences among the international guidelines to reflect the conflicting evidence in this field and the need for further research in specific areas.

Stimulant Drugs and Stimulant Use Disorder

The authors aim to summarize several key points of stimulant drugs and stimulant use disorder, including their indications, short-term and long-term adverse effects, current treatment strategies, and association with opioid medications. The global prevalence of stimulant use has seen annual increase in the last decade. Multiple studies have shown that stimulant use and stimulant use disorder are associated with a range of individual and public health issues. Stimulant misuse has led to a significant increase of overdose deaths in the United States.
