Abstract
Intermittent hemodialysis, continuous hemofiltration and prolonged daily dialysis are used for renal replacement therapy in the intensive care units. Independent of the replacement modality, antibiotic therapy must start with a high loading dose. Dose adjustment to the kidneys must follow 48 h later to prevent toxic accumulation. Dose recommendations on product labels are often underdosed. On continuous hemofiltration, meanwhile many intensivists administer a normal standard dose because the high filtration rate corresponds to a half-normal glomerular filtration rate. After intermittent hemodialysis, a dose similar to the loading dose will be needed. On day off dialysis, the maintenance dose must be adjusted to the failing kidney function. Immediately after prolonged daily dialysis, a loading dose should be given; with twice daily dosing the maintenance dose needs to be adjusted to kidney function. Therapeutic drug monitoring is recommended for gentamicin, vancomycin, piperacillin, meropenem and voriconazole. Due to pharmacodynamic reasons, the target concentration corresponds to the concentration producing the half-maximum effect. Accordingly, the target concentration is the normal peak for concentration-dependent action with bolus dosing. The target is the average steady-state concentration for antibiotics with time-dependent action and continuous infusion.

Abstract
Interactions between lung and kidney can significantly affect the course of acute diseases, a phenomenon that was first observed in the 1950s by describing pulmonary dysfunction in uremic patients. From animal experiments there is ample evidence for remote lung injury following acute kidney injury (AKI), with an increased risk for the development of pulmonary edema and acute respiratory distress syndrome (ARDS). Coincident ARDS and AKI are associated with higher rates of intubation and mechanical ventilation, significantly prolonged weaning from mechanical ventilation and increased mortality. On the other hand, acute lung diseases and mechanical ventilation can promote the development of AKI and are associated with increased mortality when AKI is also present. These bidirectional interactions may include hemodynamic adverse effects during mechanical ventilation or volume overload as well as the release or decreased clearance and metabolism of proinflammatory mediators (e.g., interleukin-6 and tumor necrosis factor-α), which may induce and aggravate distant organ injury. The aim of this work is to examine the interactions between lung and the kidney in critically ill patients, as well as discuss potential preventive approaches.

[PMID: 29594317 DOI: 10.1007/s00063-018-0413-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2018] [Accepted: 02/26/2018] [Indexed: 12/19/2022]
Abstract
BACKGROUND Acute kidney injury (AKI) has both high mortality and morbidity. OBJECTIVES To prevent the occurrence of AKI, current recommendations from the renal section of the DGIIN (Deutschen Gesellschaft für Internistische Intensivmedizin und Notfallmedizin), ÖGIAIN (Österreichischen Gesellschaft für Internistische und Allgemeine Intensivmedizin und Notfallmedizin) and DIVI (Deutschen Interdisziplinären Vereinigung für Intensiv- und Notfallmedizin) are stated. MATERIALS AND METHODS The recommendations stated in this paper are based on the current Kidney Disease Improving Global Outcomes (KDIGO) guidelines, the published statements of the "Working Group on Prevention, AKI section of the European Society of Intensive Care Medicine" and the expert knowledge and clinical experience of the authors. RESULTS Currently there are no approved clinically effective drugs for the prevention of AKI. Therefore the mainstay of prevention is the optimization of renal perfusion by improving the mean arterial pressure (>65 mm Hg, higher target may be considered in hypertensive patients). This can be done by vasopressors, preferably norepinephrine and achieving or maintaining euvolemia. Hyperhydration that can lead to AKI itself should be avoided. In patients with maintained diuresis this can be done by diuretics that are per se no preventive drug for AKI. Radiocontrast enhanced imaging should not be withheld from patients at risk for AKI; if indicated, however, the contrast media should be limited to the smallest possible volume.
