摘要:

An indirect calorimetry system was assembled from three readily available major components: a digital pneumotachograph, an oxygen analyzer, and a carbon dioxide analyzer. A one‐way valve, face mask, and meteorological balloon completed the system. Accuracy was assessed by comparison to direct calorimetry in hospitalized patients undergoing enteral hyperalimentation. Each subject was on continuous infusion of formula during a 7‐day metabolic balance. Direct and indirect calorimetry was performed over the last 4 days of the balance. The overall agreement between the two methods was within 1%. A simple and inexpensive calorimetry system can therefore be assembled to provide an accurate measure of resting energy expenditure.(Journal of Parenteral and Enteral Nutrition8:45–48, 1984)

摘要:

The relative safety of silicon rubber catheters allows us to use deep brachial vein catheterization when other vascular accesses are hazardous or impossible. The vein is isolated from nerve and artery after a small incision is made across the inner edge of the brachial biceps. From January 1980 until April 1982, 154 catheters were inserted and remained in place from 14–167 days. In four instances the catheter had to be replaced because the tip was not in the superior vena cava. Twice bleeding had to be controlled with an occlusive bandage. We had no incidence of clinical thrombosis. The surgical access to the deep brachial vein provides a simple and safe method for difficult and even long‐term vascular access.(Journal of Parenteral and Enteral Nutrition8:49–50, 1984)
