ReviewNew ways to reduce unnecessary variation and improve outcomes in the intensive care unit.
The care of critically ill patients and the advent of the modern day intensive care unit (ICU) present a large person power and cost burden to society. The high cost of critical care is attributed to high overhead expenses (eg, experienced staff and equipment), high resource utilization (eg, pharmaceutical resources, lab testing, imaging procedures), and high demand for services. ⋯ A number of large, randomized, prospective trials have demonstrated that protocol-based strategies can not only reduce variation and cost of ICU medicine but also improve morbidity and mortality of critically ill patients requiring ICU support. In this article, we discuss examples of these trials investigating four major areas of modern ICU medicine: ventilator management, ventilator weaning, sedation and analgesia, and blood transfusions.

Review Comparative StudyCentral venous oxygen saturation monitoring in the critically ill patient.
In the initial treatment of a critically ill patient, blood pressure, heart rate, urine output, and central venous pressure guide resuscitative efforts. Despite normalization of these variables, global tissue hypoxia may still persist and has been implicated in the development of multiorgan failure and increased mortality. ⋯ The physiology, technology, clinical uses, and rationale for ScvO2 monitoring are reviewed, including issues regarding physiologic equivalence to SvO2. The clinical use of ScvO2 monitoring, evidence-based outcome implications, and limitations of ScvO2 monitoring will also be examined.
