Alterations in cognitive functions are common in the perioperative course. Although often unnoticed by physicians, these alterations might have distinct long-term consequences for the patient with regard to everyday functioning, self-dependency, and quality of life. In recent years, however, perioperative cognition has gained increased interest, both by clinicians and scientists, and knowledge of the preventive measures of postoperative cognitive decline has become mandatory for anesthetists and surgeons. ⋯ Postoperative neurocognitive disorders are frequent complications, especially in elderly patients, with postoperative delirium being its most pronounced and acute postoperative form, predisposing the patient for long-term cognitive impairment. The incidence of postoperative cognitive decline can be reduced by implementing preventive measures during perioperative patient care as recommended by national and international guidelines.

With the growing of the aging population, increased and new methods of anesthesia and surgery allow for surgery and other interventions in older adults.Pharmacokinetics and pharmacodynamics of drugs in older adults differ from those in younger and middle-aged adults. However, the geriatric population is frequently neglected in the context of clinical trials. The present review focuses on the consequences of multimorbidity and pharmacokinetic and pharmacodynamic alterations and their implications on anesthesia. ⋯ Further research of drug effects in the aging population may include physiologically based pharmacokinetic and pharmacodynamic complex models and randomized controlled trials with thoroughly conducted geriatric assessments.

ReviewUltrasound-guided blocks for cardiovascular surgery: which block for which patient?
Regional anesthesia blocks may benefit patients undergoing cardiovascular surgery. This review coincides with the evolution of ultrasound-guided fascial plane blocks, societal concerns regarding opioid misuse and changing expectations regarding surgical recovery. ⋯ Ultrasound-guided fascial plane blocks may reduce postoperative opioid requirements. Investigation into the safety and efficacy of bilateral continuous ultrasound-guided blockade for cardiac surgery is required. Trial protocols should be embedded into enhanced recovery after surgery programs. Patient-reported and long-term outcomes are recommended.

Ex-vivo lung perfusion (EVLP) has been developed to expand the donor pool for lung transplantation recipients. The role of EVLP in organ preservation, evaluation and potential reconditioning is reviewed. ⋯ EVLP has been shown to be an effective system to expand donor pool for lung transplantation without detriment to recipients. Future potential ex-vivo developments may further improve patient outcomes as well as increasing availability of donor organs.

Hemodynamic instability is common in the perioperative period because of obligate physiologic changes that occur with surgery. Despite the frequency of such hemodynamic changes and the potential harm associated with them, particularly in the elderly, guidelines to optimize perioperative blood pressure are lacking. The present review examines recent evidence for perioperative blood pressure management in the elderly. ⋯ Precise and intentional management of hemodynamic parameters, medication regimens, and blood pressure monitoring may reduce adverse events in elderly patients undergoing surgery. Further investigation is required to identify the exact hemodynamic parameters that mitigate risk.
