Hypernatremia in the intensive care unit: an indicator of quality of care?
To assess the frequency of hypernatremia in patients who were admitted to an intensive care unit (ICU) and to determine the correlation of hypernatremia with the clinical outcomes, durations of the patients' stays in the ICU, and other clinical variables. ⋯ Despite frequent measurement of sodium levels in patients in the ICU, hypernatremia is a relatively common occurrence. Initial treatment of hypernatremia is often inadequate, and sometimes treatment is delayed. The development of hypernatremia is associated with adverse outcomes for patients developing hypernatremia in the ICU. Hypernatremia could potentially be used as an indicator of quality of care in the medical ICU.

Unilateral do-not-attempt-resuscitation orders and ethics consultation: a case series.
To describe the role of an ethics consultation service in unilaterally withholding cardiopulmonary resuscitation. ⋯ The process of ethics consultation is useful in resolving disagreements over withholding cardiopulmonary resuscitation and other treatment and can frequently result in a consensus. Hospital policies that permit unilateral treatment limitation should be based on a model that is process-based and that encourages interdisciplinary participation in decision-making, such as that recently proposed by the Houston Task Force.

Randomized Controlled Trial Comparative Study Clinical TrialThe ex vivo antimicrobial activity and colonization rate of two antimicrobial-bonded central venous catheters.
Catheter-related sepsis is an important complication associated with the use of central venous catheters. Recent studies have suggested that antimicrobial-bonded catheters may reduce catheter colonization and catheter-related sepsis. The aim of this study was to determine the relationship between the antimicrobial activity and the colonization rate of two commercially available antimicrobial-bonded central venous catheters. ⋯ The Bio-Guard central venous catheter had greater ex vivo antimicrobial activity against MRSA, S. epidermidis, and E. faecalis compared with the ARROWgard catheter, and this was associated with a significantly lower rate of catheter colonization.

Given the high costs of delivering care to critically ill patients, practitioners and policymakers are beginning to scrutinize the costs and outcomes associated with intensive care. Health economics is a discipline concerned with determining the best way of using resources to maximize the health of the community. This involves addressing questions such as which procedure, test, therapy, or program should be provided, and to whom, given available resources. ⋯ Economic evaluations use analytic techniques to systematically consider all possible costs and consequences of clinical actions. Although they should never form the sole basis for clinical decisions for individual patients, economic evaluations offer potentially useful information at different levels of decision-making.

Comparative StudyUse of intraosseous blood to assess blood chemistries and hemoglobin during cardiopulmonary resuscitation with drug infusions.
To compare intraosseous with central venous blood samples for biochemical analyses and hemoglobin levels during cardiopulmonary resuscitation (CPR) and during cardiopulmonary resuscitation with infusion of sodium bicarbonate, epinephrine, and saline boluses through the intraosseous site. ⋯ Intraosseous and central venous blood biochemical and hemoglobin values were similar during hemodynamic stability and throughout 30 mins of resuscitation if no drugs were given through the intraosseous site. However, differences existed after 30 mins of CPR and infusions through the intraosseous site. Laboratory values may be erroneous when intraosseous blood is used during periods of resuscitation of >5 mins if drugs and fluid boluses have also been infused through the site. For reliable values, an intraosseous site for sampling only may be reasonable.
