ReviewThe malnourished surgery patient: a silent epidemic in perioperative outcomes?
As many as two of every three major surgery patients are malnourished preoperatively - a diagnosis rarely made and treated even less frequently. Unfortunately, perioperative malnutrition is perhaps the least often identified surgical risk factor and is among the most treatable to improve outcomes. ⋯ The recent publication of new surgical nutrition guidelines, the PONS score, and use of LBM assessments will allow better identification and earlier intervention on perioperative malnutrition. It is essential that in the future no patient undergoes elective surgery without nutrition screening and nutrition intervention when malnutrition risk is identified.

With new medical technologies and changing life styles, maternal demographics has changes and consequently older and sicker women are becoming pregnant.In this review, we present these different high-risk parturient populations, which were once considered rare for the practicing obstetric anesthesiologist. ⋯ Future research and implementation of international guidelines for management of these high-risk parturient population is necessary in order to reduce maternal and neonatal morbidity.

There has been a steady advance in neuromonitoring during anaesthesia. Inevitably much of the research is first done in adults and later in children. This review will focus on the recent paediatric publications (2017-2019) in two areas of neuromonitoring - measuring anaesthesia effect and cerebral perfusion and oxygenation. ⋯ The impact of anaesthesia on the EEG of small infants has some gross similarities to older children but there are fundamental differences, which mandate separate calibration of anaesthesia depth monitors. The role of nociception monitors in children has yet to be defined. Cerebral oxygenation monitoring during paediatric anaesthesia is improving our understanding of cerebral perfusion in this period, but as with almost all monitoring, evidence that its use improves outcome is not yet available.

ReviewAnaesthetic neuroprotection in children: does it exist or is it all just bad?
In the last 20 years, data from studies of laboratory animals, including nonhuman primates, have provided ample evidence that general anaesthetic drugs cause pathological changes in developing central nervous system (neurotoxicity). Recently, a new area of research has been developed in order to recognize any possible actions that can attenuate anaesthetics neurotoxicity. This review aims to provide an overview of the recent literature on neuroprotection. ⋯ Recent literature largely explores a variety of solutions in order to preserve and reduce the damage caused by anaesthetic agents. At the moment, none of the presented solutions regarding neuroprotection is applicable in clinical setting. Further research studies are needed.

ReviewThe patient with hypertension and new guidelines for therapy.
Hypertension is a leading disease in preoperative clinics; nearly 60% of patients over 60 years have it. Many guidelines have been published for the diagnosis and treatment of hypertension. Last year, the American College of Cardiology/American Heart Association and European Society of Cardiology and European Society of Hypertension made new recommendations for diagnosis and management, with special emphasis on targets, nonpharmacological treatment, and management of the elderly patient, and pharmacological therapy. We will review relevant concordances and differences that are important for the anesthesiologist and perioperative management. ⋯ New guidelines could increase the burden of patients with pharmacological treatment that will need surgery and require case by case considerations. The scarcity of information demands trials about blood pressure management and consensus about antihypertensive medications in perioperative period.
