Clinical TrialUse of femoral venous catheters in critically ill adults: prospective study.
To determine the frequency of clinically important complications of femoral venous catheters. ⋯ Femoral venous catheterization offers an alternative site of insertion to the subclavian and jugular veins for central venous access in the critically ill. The occurrence rate of clinically important complications is acceptably low.

To assess the resting energy expenditure of hospitalized patients with pancreatitis. ⋯ Resting energy expenditure is variable in patients with pancreatitis (77% to 139% of predicted energy expenditure). The Harris-Benedict equations are an unreliable estimate of caloric expenditure. Septic complications are associated with hypermetabolism and may be the most important factor influencing resting energy expenditure in pancreatitis patients.

Validity of a disposable end-tidal carbon dioxide detector in verifying endotracheal tube position in piglets.
the most reliable methods for confirming endotracheal tube placement are direct visualization of passage through the vocal cords and documentation of CO2 in the expired gas. We evaluated the use of a disposable colorimetric CO2 detector for verifying endotracheal tube position in small animals. The end-tidal CO2 (Petco2) detector was tested in 11 piglets with the endotracheal tube sequentially in the trachea, the esophagus, the esophagus with a carbonated beverage in the stomach, the esophagus after bag-mask ventilation. Endotracheal tube position was confirmed in all cases by direct visualization and capnometry. ⋯ This disposable Petco2 detector is highly sensitive and specific for verifying endotracheal tube placement in this nonarrest piglet model.
