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.

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.

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.

ReviewPatients with left ventricle assist devices presenting for thoracic surgery and lung resection: tips, tricks and evidence.
Over a thousand left ventricular-assist device (LVAD) implants were performed for heart failure destination therapy in 2017. With increasing survival, we are seeing increasing numbers of patients present for noncardiac surgery, including resections for cancer. This article will review the relevant literature and guidelines for patients with LVADs undergoing thoracic surgery, including lung resection. ⋯ Successful thoracic surgery requires understanding of the LVAD physiology. Modern devices are preload dependent and afterload sensitive. The effects of one-lung ventilation, including hypoxia and hypercapnia, may increase pulmonary vascular resistance and impair the right ventricle. Successful surgery necessitates a multidisciplinary approach, including thorough preoperative assessment; optimization and planning of intraoperative management strategies; and approaches to anticoagulation, right ventricular failure and LVAD flow optimization. This article discusses recent evidence on these topics.

ReviewImpact of geriatric co-management programmes on outcomes in older surgical patients: update of recent evidence.
To determine the impact of geriatric co-management programmes on outcomes in older patients undergoing a surgical procedure. ⋯ There was a shorter length of stay, less mortality and a lower readmission rate. However, there was uncertainty whether the results are clinically relevant and the GRADE of evidence was low. It was uncertain whether the outcomes time to surgery and complications were improved. The evidence is limited to hip fracture patients.
