We developed consensus management guidelines for patients admitted with chest pain, pulmonary edema, and syncope and used these guidelines to examine practice variation and the effects of physician feedback on decision making in 1145 consecutive admissions to three medical intensive care units. Data collection included a 6-month baseline period and two 6-month physician feedback periods. Hospital length of stay fell from 8.34 days to 7.41 and 7.14 days during feedback; intensive care unit length of stay fell from 2.45 days to 2.23 and 2.07 days. ⋯ Multiple linear regression showed that feedback correlated with reductions of 0.79 days (confidence interval, 0.12 to 1.46) in hospital length of stay and 0.21 days (confidence interval 0.05 to 0.37) in intensive care unit length of stay. This effect was most apparent in patients not requiring any intervention, but with a major complication. During the 6-month follow-up, mortality, readmission, and urgent readmission rates were similar for patients admitted in baseline and feedback periods.

A prospective study of 126 surgical patients from two institutions was undertaken to assess the impact of pulmonary artery catheterization in surgical intensive care units. Before catheterization, surgical residents were asked to predict pulmonary artery wedge pressure, cardiac output, systemic vascular resistance, and plan of therapy. ⋯ Catheterization results prompted a major change in therapy in 50% of patients. The data suggest that hemodynamic variables obtained from pulmonary artery catheterization improve the accuracy of bedside evaluation and lead to alteration in therapy, particularly in patients whose pulmonary artery wedge pressure predictions were poor.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative pain control with a continuous infusion of epidural sufentanil in the intensive care unit: a comparison with epidural morphine.
A prospective, randomized, double-blind trial was conducted to compare the analgesic actions and side effects of sufentanil continuously infused (5 micrograms/h) into the lumbar epidural space (L2-3) with those of an infusion of lumbar epidural morphine (0.5 mg/h). Forty patients admitted to an intensive care unit after elective major abdominal surgery participated over a varying period of 24-40 h. Post-operative pain was treated with an epidural bolus of either sufentanil (50 micrograms) or morphine (5 mg), followed by a continuous infusion of the same opiate. ⋯ The incidence of nausea and vomiting, pruritus, and drowsiness was similar in the two groups. In spontaneously breathing patients there were no respiratory complications requiring treatment. Forced vital capacities were statistically significantly better during the first 1-4 h with sufentanil.

Case ReportsKetamine by continuous infusion for sedation in the pediatric intensive care unit.
ICU physicians generally rely on either narcotics or benzodiazepines to provide analgesia and sedation. We describe five patients in whom ketamine administered as a bolus dose of 0.5 to 1.0 mg/kg, followed by a continuous infusion of 10 to 15 micrograms/kg.min, provided effective sedation and analgesia without significantly compromising cardiorespiratory function. ⋯ With ketamine, no reduction in mean arterial pressure from baseline was noted in any patient. As with any form of iv anesthesia, ketamine can have cardiorespiratory side-effects; therefore, the means to manage these effects should be readily available.

Approximately 2 million people die in the United States each year, 80% of them in acute- or chronic-care institutions. Physicians now have at their disposal interventions that can postpone death in almost every instance. ⋯ On the other hand, the fact that medical resources are becoming increasingly expensive and scarce will inevitably lead to rationing. The critical-care physician will be caught in the middle--orchestrating clinical care to balance the interests of individual patients and families against those of the larger community.
