ReviewClinical utilization of pulmonary artery catheter monitoring.
Since the introduction of PA catheter monitoring in 1970, the applications for it have dramatically broadened. PA catheters are used to obtain hemodynamic data for the assessment, monitoring, and therapeutic management of critically ill, high-risk surgical patients. Because of potential complications associated with PA catheter monitoring, numerous editorials and articles have questioned the procedure's risk-to-benefit ratio. ⋯ Problems may stem not from technology but from the knowledge and expectations of clinicians. "Human" complications from inadequate understanding of the physiological data is not uncommon. Measured pressures by themselves can be misleading; indeed use of absolute numbers rather than trends or relative changes in the values monitored can compromise clinical assessment. Overzealous acceptance and utilization of any quantitative measurement without sound clinical judgment is fraught with failure.

Randomized Controlled Trial Clinical TrialParenteral nutrition in the critically ill: use of a medium chain triglyceride emulsion.
The study investigated the use of an intravenous lipid emulsion containing medium chain triglycerides (MCTs) in critically ill patients, and compared the effects with those of a conventional long chain triglyceride (LCT) preparation. ⋯ MCTs are rapidly hydrolysed and oxidised to fatty acids and ketones which can be readily utilised. This study indicates that intravenous lipid emulsion containing MCT are safe in critically ill patients and may have advantages over LCT. The number and range of patients studied was, however, small and larger studies are needed.

Clinical TrialHemodynamic effects of sodium bicarbonate in critically ill neonates.
To analyze the cardiovascular effects of sodium bicarbonate in neonates with metabolic acidosis. ⋯ Sodium bicarbonate in neonates with metabolic acidosis induces an increase in contractility and a reduction in afterload.
