The papers have been grouped into categories haemodynamic monitoring goal-directed therapy cardiac enzymes and critical care metabolic considerations in cardiovascular performance thrombosis prevention physiology and procedures and techniques. Introduction This review article summarizes original research papers in cardiology and critical care published in 2005 in Critical Care. The papers are grouped into topics for ease of reference. Haemodynamic monitoring The volume of distribution of intravenous glucose can be used to estimate central extracellular fluid volume and cardiac preload. Ishihara and colleagues 1 assessed the utility of standard arterial blood gas glucose analyzers found in the intensive care unit ICU in accurate calculation of this volume. Previous work by the group 2 demonstrated that injection of a small bolus of glucose 5 g followed by serial measurements of glucose concentration from arterial samples allowed calculation of the initial distribution volume of glucose IDVG . This calculated volume was independent of preinjection glucose concentration and concomitant infusions of glucose and or insulin. Animal studies by the group showed a close correlation between IDVG and intrathoracic blood volume implying clinical utility as a marker of cardiac preload 3 . Their recent study 1 used preinjectate and 3 min glucose concentrations to derive approximated IDVG. The approximated IVDG was shown to correlate well with .
