Performance of Automated Telemetry in Diagnosing QT Prolongation in Critically Ill Patients.
QT prolongation increases the risk of ventricular arrhythmia and is common among critically ill patients. The gold standard for QT measurement is electrocardiography. Automated measurement of corrected QT (QTc) by cardiac telemetry has been developed, but this method has not been compared with electrocardiography in critically ill patients. ⋯ QTc determination by telemetry has poor agreement and moderate correlation with electrocardiography. However, telemetry has an acceptable area under the curve in ROC analysis with tolerable sensitivity and specificity depending on the cutoff used to define prolonged QT. Cardiac telemetry should be used with caution in critically ill patients.

Inferior Vena Cava Collapsibility Index and Central Venous Pressure for Fluid Assessment in the Critically Ill Patient.
To determine the correlation of sonographic evaluation of inferior vena cava diameter and its collapsibility index with central venous pressure in both spontaneously breathing and mechanically ventilated patients in surgical ICU. Study Design: Cross-sectional study. ⋯ Total number of patients was 126. A significant correlation was seen between IVC measurements (inferior vena cava diameters and the collapsibility index) and CVP, (p<0.001), but the regression coefficients were less in patients who were mechanically ventilated (r=0.779 for IVC maximum diameter and -0.725 for collapsibility index) than the patients who were breathing spontaneously (r=0.850 for IVC maximum diameter and -0.899 for collapsibility index) Conclusion: Evaluation of IVC diameter and its collapsibility index is an easy and non-invasive method to evaluate intravascular volume status of critically ill patients. Its use is more helpful in patients who are spontaneously breathing than those who are mechanically ventilated. Key Words: Central venous pressure, Fluid status, Inferior vena cava diameter.

First goal in an emergency department must be the immediate recognition of patients at risk. The primary success of therapy depends mainly on whether a critical risk is identified immediately upon arrival at the central emergency department and appropriate therapy is initiated. In order to identify critical patients among the many patients with a wide range of diseases and, nurse-assisted initial assessment systems can help. The assessment thus represents a complex decision-making process to identify critically ill patients in times of high patient volume and limited resources.
