Acute kidney injury (AKI) is a common and serious complication that significantly increases morbidity, mortality, and cost of care after surgery. In this article, we review recent studies that deal with strategies for renal protection and the prevention of AKI after surgery. ⋯ Early identification of patients at risk for AKI is crucial to apply any protective intervention. An improved perioperative management is required to prevent AKI. Although pharmacological therapies aiming to protect AKI are under evaluation, hemodynamic optimization and avoidance of nephrotoxic drugs are critical for perioperative patient.

The diagnostic and therapeutic use of radiation modalities is an integral part of cancer care that is being used more frequently. Organization and planning for anesthesia out of the operating room poses many challenges that are addressed in this review. ⋯ Anesthesia care in the radiation suites is increasingly in demand for the diagnosis and treatment of cancer patients. Organization of all aspects of anesthetic care in radiation suites can be challenging. Planning for each type of procedure and individual patients as well as equipment set up and postoperative care is evolving.

Sepsis affects patients of all ages with multiple comorbidities and underlying diagnoses, and is the result of infection by many potential pathogens infecting various organs or sites. Many molecules have been clinically tested in recent years for their potential immunomodulatory effects, but have been shown to have no beneficial effects on outcomes in heterogeneous populations of patients with sepsis. There are, therefore, no specific antisepsis therapies and mortality and morbidity rates remain high despite improved overall management of these patients. This review covers promising agents currently used in clinical trials. ⋯ Despite multiple trials of potential therapies for sepsis, no strategies have yet been persistently shown to have beneficial effects on outcomes. The main reason for the disappointing results is that patient populations in these studies have been too heterogeneous. Selecting patients on the basis of general symptoms is not enough. Rather patients should be selected according to the likely action of the drug in question. To achieve this, improved biomarkers of sepsis and of the immune response are needed and the activities of the individual agents need to be carefully characterized. New candidates are being developed and the results of ongoing and recent clinical trials of immunomodulatory therapies are eagerly awaited as new therapies for sepsis are urgently needed.

ReviewAdult and pediatric anesthesia/sedation for gastrointestinal procedures outside of the operating room.
This review presents current trends of safe and efficient anesthesia and sedation for adults and children for gastrointestinal procedures outside of the operating room with a special focus on total intravenous anesthesia (TIVA), target-controlled infusion (TCI), intravenous or topical lidocaine, and the use of the video laryngoscope. ⋯ Both anesthesiologists and nonanesthesiologists have to achieve a consensus and develop quality-improvement strategies to provide safe and efficient anesthesia and sedation for gastrointestinal procedures outside of the operating room for pediatric and adult patients. Techniques using TIVA, TCI, intravenous or topical application of lidocaine, and the video laryngoscope may improve and facilitate gastrointestinal procedures for the patients, the anesthesiologists, and the gastroenterologists.
