Reviews and summaries of research related to AACN 1980 research priorities: clinical topics.

This article reviews and summarizes the research conducted following publication of the 1980s American Association of Critical-Care Nurses' clinical research priorities. Original research conducted on the clinical priority topics between 1981 and 1991 was included. Review articles, doctoral dissertations, theses and abstracts were excluded unless judged to provide important information on the topic. Following the statement of each priority, progress in the area is summarized. Limitations and measurement issues are discussed as appropriate. Recommendations for future research are provided, and progress in the area is summarized.

Clinical safety and cost of heparin titration using bedside activated clotting time.

OBJECTIVE: To evaluate the clinical safety of heparin titration and the procedural cost of anticoagulation measurement using bedside low-range activated clotting time. DESIGN: Quasi-experimental study using data gathered through retrospective record review. SETTING: Coronary care, medical intensive care and telemetry units of a community hospital. SUBJECTS: Sample of 102 patients undergoing elective percutaneous transluminal coronary angioplasty. INTERVENTION: Intravenous heparin therapy was titrated using low-range activated clotting time in 51 percutaneous transluminal coronary angioplasty patients. Data from this group were compared to a matched sample of 51 angioplasty patients whose intravenous heparin therapy was titrated using activated partial thromboplastin time. RESULTS: No differences in procedural, early or late complications were found between the groups. The cost of managing heparin therapy with low-range activated clotting time was less than with activated partial thromboplastin time. CONCLUSION: These results suggest that titrating heparin therapy based on bedside low-range activated clotting time for the angioplasty patients in this sample was as safe as with activated partial thromboplastin time. Use of bedside low-range activated clotting time saved money for the hospital.

Determining AACN's research priorities for the 90s.

The American Association of Critical-Care Nurses completed a three-phased process of priority identification for critical care nursing research. In phase 1, a 78-item survey was generated following a comprehensive review of potential research topics. In phase 2, approximately 1000 critical care nurses rated each item on the survey for importance to critical care nursing. Based on these results, the AACN Research Committee formulated a clinical and a nonclinical (contextual) list of research topics. Each list contained 25 topics. In phase 3, topics were given final rankings at a 1-day Consensus Conference on Research Priorities. Both Likert-type and magnitude estimation scaling were used to determine priority ranking of items on each list. As a result, both clinical and contextual research priorities were established for AACN.

Moving beyond: a generative philosophy of science.

Philosophies of science are perhaps the most covert yet significant forces influencing the direction of change within disciplines. Although the era of logical positivism has waned for many disciplines, newer philosophies may not be satisfactory, especially for the applied disciplines. This article describes an alternative philosophy of science with special significance for nursing. This philosophy was influenced by several of the major existing philosophies, but especially by the paradigmatic view espoused by Thomas Kuhn. The generative philosophy of science was named because of its focus on generating growth among the applied disciplines. Members of these disciplines study questions with social significance and human application. This article defines major concepts, describes relationships among concepts and discusses implications for the development of nursing science and the nursing discipline.

Effect of nitroglycerin ointment placement on headache and flushing in healthy subjects.

The purpose of this study was to determine the effect of site of nitroglycerin ointment placement on headache and flushing in healthy subjects. Twenty-six subjects were given two doses of nitroglycerin ointment 3 hr apart in a randomly assigned arm-chest sequence or chest-arm sequence. Subject reports of headache and flushing using the visual analogue scale were recorded. There were no significant differences in headache or flushing based on the site or sequence of placement. Thus, the practice by nurses of routinely teaching patients to vary the site of nitroglycerin ointment placement to minimize side-effects must be questioned.

[Intravascular volume expansion and intravenous nimodipine in the treatment of cerebral vasospasm after surgical treatment of intracranial aneurysm].

The advantage of calcium antagonist on cerebral arterial spasm during the peri-operative period has been recently demonstrated. However, the role of volemia and cardiac output in the pathogenesis of arterial spasm seems predominant. The basal hemodynamic profile of 17 patients operated for an intracranial aneurysm was investigated. The hemodynamic and neurological modifications induced by treatment with nimodipine, modification of blood volume and the use of inotropic drug was subsequently analysed. In 8 patients there was a clearcut hypovolemia with diminished cardiac index whereas in 9 other patients there were low filling pressures with an unmodified cardiac index. As early as the 48th hour of treatment, there was an improvement of Hunt and Hess score in 12 patients whereas in 5 others the score remained unchanged. Two death occurred due to the extension of secondary ischemic lesions. This study seems to confirm the aggravating role of hypovolemia in the occurrence of vasospasm and the neurological improvement due to the association of a calcium antagonist, restoration of blood volume with or without a vasoconstrictor.

Social support and psychological adjustment to chronic coronary heart disease: operationalization of Johnson's behavioral system model.

No comprehensive theory of social support and psychological adjustment to chronic illness such as coronary heart disease (CHD) exists. This article reviews the literature on social support and adjustment to CHD from the perspective of Johnson's behavioral system model. It is argued that the quality of social support or nurturing is the major factor predicting cardiac crippled behaviors or dependency following myocardial infarction (MI). The variables of self-esteem, anxiety, depression, and perceptions of functional capacity are identified as variables affecting choices such as return to work and adherence to the treatment regimen and the behavioral outcome of dependency following MI.

[Interaction of nimodipine and isoflurane in surgery of intracranial aneurysm].

A moderate controlled hypotension has been performed with isoflurane in the presence of nimodipine (4 mg.h-1) on ten patients anesthetized for cerebral aneurysm clipping. The administration of both drugs induced a dose-dependent hypotension secondary to the reduction of the systemic vascular resistance without impairment of cardiac index. Nimodipine did not modify the cardiovascular effects of isoflurane. It is concluded that intravenous administration of nimodipine should be continued during the operative period.

Effect of nitroglycerin ointment placement on the severity of headache and flushing in patients with cardiac disease.

Fifty-six patients with cardiac disease participated in a study to determine the effect of site placement on patient reports of headache and flushing after topical nitroglycerin ointment placement. Nitroglycerin was placed on the upper arm, chest, and pelvis in random order. Approximately 30 minutes after application, patients were asked to evaluate their headache and flushing using a visual analogue scale. No significant difference in the severity of side effects was found when the three sites were compared by multivariate analysis of variance with repeated measures. The clinical practice of instructing patients to vary the site placement of nitroglycerin ointment to avoid side effects was not supported.
