Variability in dobutamine pharmacokinetics in unstable critically ill surgical patients.
To delineate the variability in the pharmacokinetics of dobutamine over time in an unstable critically ill adult surgical patient population concurrently receiving therapeutic interventions to optimize oxygen delivery and consumption variables. ⋯ Dobutamine pharmacokinetics in adult critically ill patients is best described by a first-order model. Pathophysiologic factors may have an effect on the pharmacokinetics of dobutamine which appears to change over time. Both inter- and intrapatient variability in infusion rate administered and resultant serum concentrations were wide, suggesting that infusion rate should be guided by clinical end points rather than by predetermined values.

Comparative Study Retracted PublicationIs continuous cardiac output measurement using thermodilution reliable in the critically ill patient?
Evaluation of continuous cardiac output monitoring based on the thermodilution technique in the critically ill. ⋯ Continuous monitoring of cardiac output using a modified pulmonary artery catheter with a heated filament has proven to be accurate and precise in the critically ill patient when compared with the "standard" intermittent bolus thermodilution technique. The continuous monitoring technique enhances our armamentarium for more intensive monitoring of these patients under a variety of circumstances.

[Patient categories and use of staff in transportation of patients between hospitals in Denmark].
Questions about how many and how far patients are transported from one hospital to another in Denmark were put to assistant matrons of anaesthesiological wards. They were also asked about what type of patients they accompanied on interhospital transports. ⋯ The patients are mostly neurosurgical and paediatric patients. Apart from the nurse from the anaesthesiological ward, there is usually also a doctor from another ward who accompanies the patient.

ReviewThe role of total parenteral nutrition in critical illness: guidelines and recommendations.
Critically ill patients experience a multitude of metabolic derangements in response to sepsis, shock, and severe injury. The result of extreme stress is characterized by alterations in carbohydrate and fat metabolism and persistent catabolism of lean body mass. ⋯ In this article, the author identifies the patient at risk, defines the appropriate time to initiate parenteral nutrition, and outlines current recommendations for energy and protein prescription. The author also briefly reviews administration issues, discusses possible complications of therapy, and defines effective strategies to monitor the response to therapy.
