ReviewCan we abandon daily routine chest radiography in intensive care patients?
Two different schools of thought exist on the utility of daily routine chest radiographs in intensive care unit (ICU) patients: some ICU physicians argue that daily routine chest radiographs are indicated in all patients who have cardiopulmonary problems or are receiving artificial ventilation. Others state that chest radiographs should be made on indication only, for example, following a change in clinical status or change of supportive devices. ⋯ A restrictive strategy has been compared with a daily routine strategy in only 2 clinical trials: 1 study conducted in a pediatric ICU (pediatric ICUs usually have low mortality rates), and the other a rather small (and probably underpowered) study. The debate about discontinuing daily routine chest radiographs in the ICU is still not settled.

Comparative Study Clinical TrialBispectral index monitoring during the administration of neuromuscular blocking agents in the pediatric intensive care unit patient.
Bispectral index (BIS) values were prospectively recorded in pediatric intensive care unit patients receiving continuous infusion of a neuromuscular blocking agent. Sedation was provided by a continuous infusion of midazolam or propofol. The BIS number was recorded by a bedside computer every 10 seconds but was concealed from health care workers. ⋯ Oversedation was more likely with propofol than midazolam. During the use of neuromuscular blocking agents, oversedation is a common occurrence. Physiologic parameters are not an accurate means of assessing the depth of sedation.

ReviewManagement of cardiogenic shock attributable to acute myocardial infarction in the reperfusion era.
Cardiogenic shock is the leading cause of death among patients hospitalized with acute myocardial infarction. It is defined as tissue hypoperfusion resulting from ventricular pump failure in the presence of adequate intravascular volume. ⋯ However, emergency percutaneous coronary intervention or coronary artery bypass graft surgery is required to decrease mortality rates. Novel approaches, including inhibition of nitric oxide synthase and new mechanical support devices, may further decrease mortality rates, which remain high despite reperfusion therapy.
