Inhalational anaesthetics, ozone depletion, and greenhouse warming: the basics and status of our efforts in environmental mitigation
We describe recent evidence examining the benefits and harms associated with their use. Recent findings The environmental harms associated with desflurane and nitrous oxide likely outweigh any purported clinical benefits. Life cycle analyses are beginning to address the many gaps in our understanding, and informing choices made on all aspects of anaesthetic care. There is, however, an urgent need to move beyond the debate about anaesthetic technique A vs. B and focus also on areas such as sustainable procurement, waste management, pharmacological stewardship and joined-up solutions. Summary There is now compe...

Recent advances in understanding cognitive and behavioural alterations after early-in-life anaesthesia exposure and new mitigation/alternative strategies in preclinical studies
Purpose of review Long-term behavioural and cognitive impairments after exposure to general anaesthetics during infancy is an intensely investigated and controversial topic. Recent clinical studies with prospective assessments associate exposure with long-term behavioural alterations rather than cognitive impairments. This review aims to provide an understanding of the long-term cognitive impairments and behavioural alterations found in recent animal studies and to summarize latest advances in strategies to protect against anaesthesia-induced developmental neurotoxicity (AIDN). Recent findings Preclinical studie...

Ready for a “breakthrough” with ketamine? A look at recent pharmacological insights!
Purpose of review To update pharmacological insights on ketamine integrating information from different disciplines for developing steps to “breakthrough” approaches in clinical challenges. Recent findings Pharmacokinetic/pharmacodynamic (PK/PD) models have incorporated recirculation, ketamine metabolites, drug–drug interaction, and covariates such as age. Ketamine-induced relief from treatment-resistant depression has been explained by “disinhibition” of gamma-aminobutyric acid-ergic interneurons and synaptogenic mechanisms requiring neurotrophic signals. Neuroimaging/electroencephalographic investiga...

The disruptive physician and impact on the culture of safety
Purpose of review The disruptive physician is a growing problem in medicine. All too often, physician behavior negatively impacts the delivery of quality patient care. The hostile environment that certain behaviors create makes it difficult for team members advocate for their patients. It is imperative that physician practices develop and an understanding of how to identify the disruptive physician to maintain patient safety. Recent findings Disruptive physicians can damage team morale by creating a psychologically unsafe working environment. Healthcare organizations must be committed to ensuring that all team m...

Myocardial injury after noncardiac surgery – an update
Purpose of review After successfully reducing mortality in the operating room, the time has come for anesthesiologists to conquer postoperative complications. This review aims to raise awareness about myocardial injury after noncardiac surgery (MINS), its definition, diagnosis, clinical importance, and treatment. Recent findings MINS, defined as an elevated postoperative troponin judged to be due to myocardial ischemia (with or without ischemic features), occurs in up to one in five patients having noncardiac surgery and is responsible for 16% of all postoperative deaths within 30 days of surgery. New evidence...

Perioperative frailty: lessons learned and future directions
This article reviews current conceptual frameworks of frailty, references current literature and provides a practical approach to the preoperative frailty assessment with a focus on potential interventions. Recent findings A multipronged approach toward preoperative optimization should be used in patients with frailty syndrome. Oral protein supplementation and immunonutrition therapy can reduce complications in patients with malnutrition. Initiating a preoperative physical exercise regimen may mitigate frailty. Nonpharmacologic interventions to reduce preoperative anxiety and improve mood are effective, low-cost adj...

How new biomarkers aid the anesthetist to detect and prevent perioperative acute kidney injury
Purpose of review Acute kidney injury (AKI) is underestimated but common in the perioperative setting. Although the association of this syndrome with an increased morbidity and mortality has been well established, little progress has been made in the diagnosis or prevention of AKI in recent years. This is partly due to the late detection of AKI by conventional criteria based of functional biomarkers, serum creatinine, and urine output. In addition, conceptually AKI is now recognized as being part of a continuum, in which preventive intervention is time critical. This review will summarize the current best available evi...

Immunomodulators in anesthesia
Purpose of review Anesthetics are known to have immunomodulatory effects. These can be detrimental, inducing immunosuppression and facilitating the development of opportunistic infections, especially when used at high doses, for prolonged periods, or in patients with preexisting immune deficiency; or beneficial, modulating the inflammatory response, particularly in critical illness and systemic hyperinflammatory states. Recent findings Anesthetics can have microbicidal properties, and both anti- and pro-inflammatory effects. They can act directly on immune cells as well as modulate immunity through indirect path...

Current concepts in the evaluation and management of preoperative anemia
Purpose of review In the past years, patient blood management (PBM) has evolved to improve patient‘s care and safety. Anemia is one of the most common medical diseases in the world and is an independent risk factor for morbidity and mortality. Iron deficiency is the main cause for anemia and constitutes a potentially preventable condition with a great impact on surgical outcome. However, preoperative anemia management is not yet established in most hospitals. Changing workflows and re-thinking is challenging. Numerous published studies confirmed the positive effect of preoperative anemia diagnosis and treatment recen...

Patients with psychiatric disease: implications for anesthesiologists
Purpose of review Psychiatric illness is common in patients presenting for surgery. Overall health and surgical outcomes are adversely affected by the presence of psychiatric comorbidities. Recent findings As new treatment modalities become available, their perioperative implications need to be evaluated. These implications include drug–drug interactions, hemodynamic effects, bleeding risk, and factors affecting perioperative exacerbation of the underlying psychiatric illness. Summary From our review of the recent literature we continue to support the continuation of psychoactive agents in the periopera...

Perioperative thrombocytopenia
Purpose of review In this review, we discuss recent developments and trends in the perioperative management of thrombocytopenia. Recent findings Large contemporary data base studies show that preoperative thrombocytopenia is present in about 8% of asymptomatic patients, and is associated with increased risks for bleeding and 30-day mortality. Traditionally specific threshold platelet counts were recommended for specific procedures. However, the risk of bleeding may not correlate well with platelet counts and varies with platelet function depending on the underlying etiology. Evidence to support prophylactic plat...

Anesthetic technique and cancer surgery outcomes
Purpose of review Surgery remains integral to treating solid cancers. However, the surgical stress response, characterized by physiologic perturbation of the adrenergic, inflammatory, and immune systems, may promote procancerous pathways. Anesthetic technique per se may attenuate/enhance these pathways and thereby could be implicated in long-term cancer outcomes. Recent findings To date, clinical studies have predominantly been retrospective and underpowered and, thus limit meaningful conclusions. More recently, prospective studies of regional anesthesia for breast and colorectal cancer surgery have failed to de...
