ReviewAcute dialysis and continuous renal replacement: the emergence of new technology involving the nephrologist in the intensive care setting.
The emergence of dialytic support for patients with reversible renal failure was one of the most significant advances in critical care medicine. Supporting a patient with a failed organ till organ recovery has not had the same success with other organ failures. Despite the indispensable nature of the support, dialysis was intermittent at best, and carried its own morbidity. ⋯ Plastic membrane bio-incompatibility, human physiological responses to foreign material exposure, either in the circuit material itself or introduced from therapy methodology, pose practical and theoretical problems. Recent advances in the field of bio-artificial technology have allowed the development of functioning hybrid "blood processors," which function as a renal tubule and may be able to not only "clean" blood, but also allow for other cellular functions not currently possible with dead membrane technology. Combining living cells with a continuous delivery method may be the next significant step toward a fully functional renal replacement therapy.
