ReviewReview of the acuity scoring systems for the pediatric intensive care unit and their use in quality improvement.
Acuity scoring systems quantitate the severity of clinical conditions and stratify patients according to presenting patient condition. In the pediatric intensive care unit, the complexity and number of clinical scoring systems are increasing as their applications for clinicians, health services researches, and quality improvement broaden. This article is a review of acuity scoring systems for the pediatric intensive care unit, including examples of scoring systems available, the methods used in assessing these tools, the ways in which these systems are used, and the utility of acuity scoring systems in accurate benchmarking. It is anticipated that with increasing health care costs and competition and increased focus on medical error reduction and quality improvement, the demands for risk-adjusted outcomes and institutional benchmarking will increase; therefore, as clinicians, academicians, and administrators, it is imperative that we be knowledgeable of the methods and applications of these acuity scoring systems to ensure their quality and appropriate use.

Review Case ReportsAcute adrenal insufficiency after a single dose of etomidate.
Acute adrenocortical insufficiency is a critical care emergency characterized by hemodynamic instability, lethargy, and cardiovascular collapse. Acute adrenal insufficiency has many etiologies, from rapid withdrawal of exogenous glucocorticoids to adrenocortical destruction to poor adrenal reserve after administration of steroid synthesis inhibitors. ⋯ A case is presented of acute adrenocortical insufficiency and crisis after a standard induction dose of etomidate. Acute adrenal insufficiency should be suspected in intensive care unit patients who have undergone general anesthesia with etomidate induction and present with hypotension refractory to standard vasopressor administration.

ReviewCritical care issues in the patient after major joint replacement.
Admission rates of orthopedic patients to intensive care units are increasing. Thus, an intensivist's familiarity with specific problems associated with major joint replacement surgery is of utmost importance in order to meet the needs of this particular patient population. ⋯ Perioperative risk factors for morbidity and mortality and the epidemiology, diagnosis, and treatment of cardiopulmonary complications in this patient population are discussed. Procedure-specific complications such as fat embolism and acrylic bone cement-related issues are reviewed.

Symptomatic arrhythmias are frequently observed in the intensive care unit and often lead to significant hemodynamic compromise because of the presence of multisystem disease. In particular, prompt evaluation of patients with tachycardia is critical because treatment depends on the accurate diagnosis of the arrhythmia mechanism. ⋯ For wide complex tachycardia, evaluation of the atrioventricular relationship and QRS morphology are critical, and for narrow QRS complex tachycardias, evaluation focuses on identification of the location and morphology of P waves. Bradycardia can arise from sinus node dysfunction or atrioventricular conduction block.

Older adults comprise 48% of the critically ill population in intensive care units and will continue to represent a substantial proportion of patients requiring intensive care for decades to come. Aging both decreases the reserve capacity of vital organs and increases the risk of concurrent illnesses that challenge the respiratory system, such as pneumonia, renal failure, or heart diseases. ⋯ For those who require mechanical ventilation, protocols to identify patients who are ready to wean should facilitate liberation from respiratory support and reduce complications of mechanical ventilation. Finally, allocation of potentially limited health care resources necessitates knowing about the risk-benefit of mechanical ventilation and other treatment for respiratory failure in this population.
