TASK DEFINITION: Indicate the presence of numerical data in the abstract (whether numerical data plays a key role in medical records), solely using the information from the abstract.
PROBLEM: Abstract: The ability to breathe spontaneously through an endotracheal tube is a usual prerequisite before an intubated patient can have it removed. Other researchers have measured air flow resistance through endotracheal tubes. In this study, we evaluated work of breathing in joules per min and tension-time index while three normal volunteers breathed through different sized endotracheal tubes. Four 27.5-cm endotracheal tubes were used. Subjects breathed with a constant tidal volume of 500 ml. By increasing respiratory frequency, minute ventilation was increased from 5 to 30 L/min. As tube diameter decreased, work and the tension-time index increased. Changes were magnified at higher minute ventilations through the 6- and 7-mm endotracheal tubes, and the tension-time index critical fatigue level of 0.15 was approached or exceeded.

SOLUTION: Yes

PROBLEM: Abstract: Rubber glove intolerance is a common dermatological problem and hypersensitivity of both delayed and immediate types occur. In order to study immediate skin reactions induced by rubber gloves, 15 patients with discomfort and itch produced by rubber gloves were examined. The patients were provoked by wearing rubber gloves, scratch tested with gloves, rubber chemicals and powders. RAST-tests were performed using an extract from the rubber tree (Hevea brasiliensis). In 6/15 patients, contact urticaria was confirmed, in 3 of whom IgE antibodies to latex were demonstrated.

PROBLEM: Abstract: In the critically ill child, administration of fluids and medications via the intraosseous route often proves life-saving. The authors describe the case of a child with status epilepticus in whom phenytoin was administered via the intraosseous route, and seizure resolution and therapeutic serum levels were achieved. Intraosseous drug administration should be reserved for the rare critically ill child in whom vascular access proves impossible.
