[Incidence of ventilator-associated pneumonia in patients using open-suction systems and closed-suction systems: a prospective study -- preliminary data].

This a randomized clinical trial in which 20 patients were prospectively evaluated for the incidence of ventilator-associated pneumonia (VAP), of whom 12 received endotracheal suctioning by an open-suction method and 8 by a closed-suction method. Differences in the incidence of VAP was not significantly different (p = 0.4) between closed and open suctioning. Differences in Acute Physiology and Chronic Health Evaluation II, duration of entubation, and the use of steroids were all not significant. All patients in the study used H2 antagonist and a nasogastric tube. Proceeding with the study will involve a sample increase with a possible change in the results.

[Nursing specialization program: residential model: experience of establishing oneself in a teaching hospital].

This is a report about the experience of setting up a Specialization Program for Nurses in a "Residence" format, at the school-hospital of the Federal University of São Paulo, which mixes the traditional structure of specialization programs in Brazil with the model of the resident physician practical training. It began on February 1995, with the following objectives: 1) to qualify nurses, in different specialities, by an intensive training program, on a full-time schedule; 2) to contribute to improve the process of nursing care and; 3) to increase the quality of nursing assistance in our hospital. The results of our experience allow us to suggest that's a good way to qualify nurses for the best nursing practice, and to increase nursing research in a very practical basis.

[Identification of the defining characteristics of the nursing diagnosis of excess fluid volume].

This study aimed at verifying the defining characteristics of the nursing diagnosis "Fluid Volume Excess" proposed by NANDA. Data collection was carried out within a specialized Cardiology health care setting where the 29 patients were selected by two expert nurses. The conclusion showed consonance of opinions between the two professionals in regard to the identification of nine patients with diagnosis and 20 without this type of diagnosis. The identified defining characteristics appeared in different percentages considering the studied patients.

[Effect of propranolol and metoprolol on cardiorespiratory and metabolic response to exercise].

PURPOSE: To study the effects of intravenous propranolol and metoprolol on cardiorespiratory and metabolic responses to exercise. METHODS: Two groups of anaesthetized dogs (sodium pentobarbital, 33 mg/kg) were studied at rest and moderate exercise (induced by electrical stimulation) before and after metoprolol (0.4 mg/kg, n = 7) or propranolol (0.2 mg/kg, n = 10). Haemodynamic, metabolic and respiratory variables were measured. RESULTS: There was a decrease in heart rate both at rest and during exercise after metoprolol and propranolol administration. The cardiac output, stroke volume and peripheral vascular resistance presented decreased responses to exercise after both drugs. O2 consumption and CO2 production were not altered significantly at rest but increased in a lesser degree during exercise. Propranolol administration reduced ventilation during rest and exercise, although the ventilatory response to exercise remained the same. Metoprolol administration did not affect ventilation at rest but reduced the ventilatory response to exercise leading to an increase of the PaCO2. CONCLUSION: Propranolol and metoprolol effects on cardiovascular and metabolic variables measured at rest and during exercise were the same. The ventilatory effect with metoprolol administration was different from the observed with propranolol.

[Health care models for nursing practice].

The focus of this study is the development and the choice of nursing models. It doesn't intend to discuss all the aspects involved in the development of models, but to emphasize the importance of choosing one to use in nursing clinical practice.
