The abdominal compartment syndrome is an increasingly recognized complication of both medical and surgical patients in the ICU setting. This syndrome has been described in a wide variety of clinical scenarios and results from a persistent elevation in intra-abdominal pressure characterized by graded organ system dysfunction. Manifestations of abdominal compartment syndrome include cardiovascular, pulmonary, renal, splanchnic, and neurologic impairment. ⋯ Patients at risk for abdominal compartment syndrome warrant close monitoring and we recommend prompt abdominal decompression following documentation of increased intra-abdominal pressure in the setting of physiologic compromise. Abdominal compartment syndrome can significantly contribute to the morbidity and mortality of both medical and surgical patients alike in the ICU. The signs and symptoms of abdominal compartment syndrome should become familiar to all critical care practitioners.

Effective use of sedative-hypnotic and analgesic agents is an integral part of providing patient comfort and safety. Of the numerous drugs administered, benzodiazepines, propofol, and narcotics are the most popular. Even these proven, time-tested sedative-hypnotics and analgesics are not perfect, however, and modern intensive care demands a more ideal product. ⋯ Slower bolus loading over 20 minutes results in minimally decreased heart rate and blood pressure. Continuous infusion maintains unique sedation (patients appear to be asleep, but are readily roused), analgesic sparing effect, and minimal depression of respiratory drive. More experience with dexmedetomidine infusion in medical ICU patients and patients with complex end-organ dysfunction such as respiratory failure or systemic inflammatory response syndrome is needed before conclusions can be drawn about the drug's potential for wider application and its long-term (> 24 h) safety and effectiveness.

ReviewDeveloping and implementing measures of quality of care in the intensive care unit.
As consumers, payers, and regulatory agencies require evidence regarding quality of care, the demand for intensive care unit (ICU) quality measures will likely grow. ICU providers and professional societies may need to partner with experts in quality measurement to develop and implement quality measures. ⋯ On the other hand, structure and process measures may be feasible to implement broadly. Given the steps for developing quality measures outlined in this essay and the growing evidence in the literature regarding the impact of ICU care, the future should realize the development and implementation of ICU quality indicators that are rigorously developed and provide insights into opportunities to improve the quality of ICU care.

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.
