Comparing two methods of umbilical artery catheter placement.

This study compared the conventional method of umbilical artery catheter placement with a side-entry method. Criteria for comparison were: (1) frequency of correct placement; (2) time required for placement; and (3) incidence of bleeding. Newborn infants less than 3 hours of age who required placement of a umbilical artery catheter were admitted into the study with parental consent. The sample size was 32 catheter attempts (16 conventional method and 16 side-entry method). The side-entry method resulted in more successful catheter placements and required less time without incidence of bleeding. With the conventional method, there were five failures to place the catheter and three incidents of bleeding, resulting in a total blood loss of 14 cc.

Electrocardiographic response to ice water ingestion.

To determine the necessity of restricting ice water for patients with acute myocardial infarction (MI) we performed studies in 89 patients who had been admitted to a coronary care unit with a diagnosis of acute MI or "rule out MI." Using a split-plot factorial repeated-measures design, we randomly assigned patients to position and sequence of volume. A Marquette Augmented Cardiograph was used to obtain 12-lead electrocardiogram (ECGs) at baseline and at 3, 10, and 25 minutes after ingestion of 200 or 400 ml ice water. Multivariate analysis of variance (MANOVA) was used to assess the significance of each factor alone and in interaction for both ST segments and T waves for 11 leads. The preliminary analysis of variance showed significant difference (p less than 0.10) in ST segments for position in several leads and in T waves for disease in several leads. Differences did not continue to be significant when they were considered across the four time periods (MANOVA); then time and volume were the significant variables for most leads. Mean change scores for ST segment (0.01 to 0.05) and T wave amplitude (0.01 to 0.88) were not clinically significant; however, a few patients had significant changes in ST segment of greater than 1 mm and T wave amplitude of greater than 10 mm. A few patients exhibited T wave inversion, suggesting a third level of significance: clinically detectable differences.(ABSTRACT TRUNCATED AT 250 WORDS)

Nurses and physicians must interact for valid clinical research.

The results of clinical research provide information for improving patient care. Seldom can one profession conduct research in the clinical setting without communicating with other professionals affected by the research protocol. When informed consent is obtained from the patient, an investigator may think that sufficient communication to all parties affected by a study has occurred. To conceptualize interactions observed between two professions, (i.e., nursing and medicine), five patterns are proposed: blocking research, hidden research, dumping research, negotiated research, and collaborative research. The patterns are associated with various amounts or types of communication about research. Each description of a pattern contains an example of the interactions possible in that model, a set of assumptions that underlie those interactions, and a number of potential outcomes. The interactions described are real occurrences with some details changed to prevent identification of individuals or institutions. These examples of research interactions occurred at several institutions. The outcomes listed are not all possible at the same time, but are a compilation of a number of outcomes that could occur.

Accuracy of references in nursing journals.

The purpose of this study was to quantify and classify errors in reference lists of randomly selected, recently published issues of nursing journals (n = 17) and to assess whether these errors prevented retrieval of the cited documents. Randomly selected references, 65 from clinical journals and 47 from non-clinical journals, were compared to the original sources for accuracy. Errors were classified as minor (not preventing retrieval) and major (preventing retrieval). Errors occurred more frequently in references in clinical journals, 38.4% of those reviewed, as compared to 21.3% in of non-clinical journals. Additionally, 4.6% of the clinical references contained major errors, but no major errors were located in references from the non-clinical journals. These findings have implications for all readers.

Clinical nurse researchers: strategies for success.

One response to nursing's growing commitment to grounding practice in a research base has been the development of clinical nurse researcher positions in hospitals throughout the country. Drawing on data from a nationwide survey, the authors describe goals and strategies that clinical nurse researchers and their chief nurse executives identify as contributing to successfully carrying out the clinical nurse researcher role.

A comprehensive charge system for unit supplies.

Various methods of capturing charges for supplies stocked on nursing units have been devised, such as stickers and charge slips attached to the items. Effectiveness and efficiency were not maximized through these methods. A new system customized for each unit showing daily patient charges per patient provides for an audit of inventory and for lost charges. Items from both pharmacy and central supply are included. Charge capture is maximized with relative ease for the nursing staff.

Perspectives on exercise and aging.

This discussion has particular implications for those involved in the care of the older patient with cardiac disease Without increased attention to research that addresses exercise and aging, decisions about the future activity of the elderly person who has sustained a coronary event may be biased by subjective notions. The question remains regarding whether this individual will be given the same options for rehabilitation as one who happens to be middle-aged. Clearly, there is a need to study the responses to exercise of the elderly with and without diagnosed heart disease. There is also need for a greater number of longitudinal studies such as those of Robinson et al. These studies might compare the exercise responses of active, inactive, and athletic individuals from young adulthood to old age.

A nursing practice problem: failure to observe aseptic technique.

A study was conducted to assess nurses' adherence to a recently revised policy and procedure manual. Medical-surgical nurses (n = 217) were surveyed to assess their perceived ability to perform selected clinical procedures. A sample (n = 34) of respondents was then observed performing the procedures. Analysis of the 37 errors in performance revealed an unanticipated high number of errors (n = 33) in aseptic technique. Type of errors and projected reasons for their occurrence are given.
