Airway management of critically ill patients has been enhanced by the recent introduction of several new types of artificial airways and laryngoscopes. New drugs for sedation and neuromuscular blockade have been developed to facilitate care of the intubated patient. Guidelines for management of the difficult airway have been introduced. ⋯ A consensus is evolving that TLI and tracheotomy each have clear advantages and disadvantages in prolonged airway maintenance and that multiple factors, not simply the duration of TLI, must be considered in the optimal timing of tracheotomy for each patient. Complex medicolegal and ethical issues directly impact intubation, perhaps more so than any other practice in critical care medicine. Physicians who care for critically ill patients should be familiar with these recent developments and concepts in airway management.

Comparative Study
Reproducibility of thermodilution cardiac output determination in critically ill patients: comparison between bolus and continuous method.
A semi-continuous thermodilution method (CCO) was recently developed to measure cardiac output with less risk of bacterial contamination, fluid overload, and user-induced errors than the classical bolus technique (BCO). Previous comparison between these two methods showed negligible bias. However, large limits of agreement suggest that the two methods are not interchangeable. We hypothesized that this poor agreement may be due to differences in reproducibility. ⋯ Differences in reproducibility may explain the poor agreement between the CCO and BCO methods. The better reproducibility of the CCO method allows the detection of smaller variations in cardiac output and suggests the superiority of this new method.

Pediatric intensive care units have developed as treatment areas with a concentration of specialized equipment and personnel. Critically ill children often need to be moved to and from these critical care areas for diagnostic or therapeutic procedures. Such transport may pose additional risk to the critically ill patient. ⋯ Our results would suggest that more training regarding the transport of the critically ill child are needed in our area.

To evaluate the prevalence of serum and erythrocyte magnesium (Mg) abnormalities in patients on admission to the intensive care unit (ICU) and to test the hypothesis that low levels of Mg are associated with a higher mortality. ⋯ We confirm the high prevalence of Mgs abnormalities as well as Mg deficiency on admission to a medical ICU. Low levels of Mgs and Mge are not associated with higher fatality. HyperMgs was associated with patient death.

Hypocholesterolemia and risk of death in the critically ill surgical patient.
To evaluate the additional information provided by the determination of cholesterolemia to the Acute Physiology and Chronic Health Evaluation (APACHE) II score. ⋯ Both hyper- and hypocholesterolemia have a highly significant relationship to mortality. Cholesterolemia improves the prognostic power of the APACHE II score. This result could be used to create a more powerful prognostic index.
