摘要:

A program was developed to calculate fluid, nutritional, and electrolyte intake using a Hewlett-Packard 41C (HP-41C) programmable calculator. This program simplifies calculations of infused and enteral intake of carbohydrate, lipid, amino acids, nitrogen, sodium, potassium and fluid volume in patients receiving enteral intake and up to three different venous (or arterial) infusions.

摘要:

The accuracy of a new reagent test strip (Chemstrip BG) for the quantitative estimation of whole blood glucose concentration was compared to that of a widely used test strip (Dextrostix). To perform the comparative study, venous blood specimens were obtained from 133 patients. Interpretations of reagent strip glucose readings were made by three observers who separately recorded their impressions from the two strips on each patient. These estimated levels were compared to quantitative (glucose oxidase) concentrations measured from the same specimen. Although there were significant correlations (p< 0.001) between both reagent strips and the measured values, the Chemstrip BG results more closely approximated measured values for the range of glucose concentrations encountered (10–600 mg/dl). In addition, Chemstrip BG was easier to read and measured a wider range of values than Dextrostix and, unlike Dextrostix, Chemstrip BG strips could be stored for review at a later time. This new glucose test strip accurately and rapidly determines whole blood glucose concentration at the bedside.

摘要:

We introduced telemedicine, i.e., telecommunications for delivery of health services, to alleviate scarcity and maldistribution of critical care services. For 18 months, we used interactive television to provide consultation with university-based critical care physicians for patients in the ICU of a 100-bed hospital. Telemedicine “visits” (1548) were made to 395 patients. Television consultation had greater clinical and educational impact than consultation using the telephone. Equipment was expensive but proved to be reliable and easy to use. Interactive television extended the availability of specialist expertise, but full exploitation of this technology for delivery of critical care services was not achieved. Extensive background research, currently underway at the University of Pittsburgh, is necessary before the next telemedicine demonstration.

摘要:

Pneumoperitoneum (PP) in artificially ventilated patients is usually caused by barotrauma to the lungs or by perforation of an intra-abdominal viscus. The differential diagnosis is sometimes difficult but important, as unnecessary laparotomy could result if the PP is due to pulmonary barotrauma. Three cases of PP are presented and the literature reviewed in order to demonstrate the source of the intra-abdominal gas, the factors predisposing to PP, the causes and mechanisms of PP, and its diagnosis and treatment. A classification based on the mechanism involved in the production of PP is presented.

摘要:

We report the recurrence of pneumothorax caused by ball-valving of an intrabronchial blood clot cast in a patient on mechanical ventilation. Removal of the blood clot cast by flexible fiberoptic bronchoscopy prevented further pneumothoraces. Bronchial obstruction should be considered in the mechanically ventilated patient with recurrent pneumothorax.

摘要:

15(R)-15 methyl prostaglandin E2(PGE2) was successful in the control of life-threatening hemorrhage from gastric stress erosions refractory to maximal surgical and medical intervention. 15(R)-15 methyl PGE2is an inhibitor of gastric acid secretion, aids in healing of gastric and duodenal ulcers, and exerts a cytoprotective effect on gastric mucosa independent of its antisecretory property.
