Book description

The critical care unit manages patients with a vast range of disease and injuries affecting every organ system. The unit can initially be a daunting environment, with complex monitoring equipment producing large volumes of clinical data. Core Topics in Critical Care Medicine is a practical, comprehensive, introductory-level text for any clinician in their first few months in the critical care unit. It guides clinicians in both the initial assessment and the clinical management of all CCU patients, demystifying the critical care unit and providing key knowledge in a concise and accessible manner. The full spectrum of disorders likely to be encountered in critical care are discussed, with additional chapters on transfer and admission, imaging in the CCU, structure and organisation of the unit, and ethical and legal issues. Written by Critical Care experts, Core Topics in Critical Care Medicine provides comprehensive, concise and easily accessible information for all trainees.

    Summary

    Acute renal failure (ARF) is a common condition which is a major contributor to morbidity and mortality amongst critical care patients. As renal function is highly dependent upon adequate renal blood flow and glomerular filtration pressure, oliguria is an early marker of an inadequate haemodynamic status. This chapter lists out prerenal causes, intrinsic causes and postrenal causes of renal failure. Early identification of reversible causes of renal impairment with expedient intervention may prevent progression to established ARF. Prerenal uraemia should be treated by urgent restoration of circulating volume and renal perfusion pressure and by correction of electrolyte deficits. Renal replacement therapy (RRT) is the mainstay of treatment for established acute renal failure. Survival following an episode of ARF is variable and, within the critical care environment, is largely dependent upon the accompanying pathological conditions, e.g. severe sepsis.
