We would neither be disappointed nor upset if the gas mileage on the sticker of a car didn't match our personal, real-life fuel consumption. Depending on our daily route to work, our style of accelerating and the number of passengers in our carpool, the gas mileage will vary. As soon as the falcon wing door of our car is closed and entrance to the ICU is granted, we tend to forget all of this, even though another hot rod is waiting there for us. Renal replacement therapy is like a car; it fulfills goals, such as the removal of uremic toxins and accumulated fluids, but it also "consumes" (removes) antibiotics. Unlike catecholamines, where we have the mean arterial pressure on our ICU dashboard, we do not have a gauge to measure antibiotic "consumption", i.e. elimination by renal replacement therapy. This manuscript describes the principles and basic knowledge to improve dosing of antibiotics in critically ill patients undergoing renal replacement therapy. As in modern cars, we briefly touch on hybrid therapies combining renal replacement therapy with extracorporeal lung support or adsorbent technologies that remove cytokines or bacteria. Further, the importance of considering body size and body composition is addressed, especially for choosing the right initial dose of antibiotics. Lastly we point out the dire need to increase the availability of timely and affordable therapeutic drug monitoring on the most commonly used antiinfectives, ideally using point-of-care devices at the bedside. |
