Critical care education: an examination of students' perspectives.

Specialist nursing education at the tertiary level is a relatively recent occurrence in Australia. With this move to higher education a variety of issues such as course duration, award level and clinical versus theoretical outcomes provided the impetus for this study. This study examined critical care nursing students' perceptions of undertaking post-graduate education within the higher education sector. Four themes arose from analysis of eight focus group interviews with a total of 42 students from 35 courses offered in eight universities across Australia. The first theme, student burden, included subthemes of financial, heavy workload and student-work conflicts. Student benefits, the second theme, encompassed financial and other benefits. The third theme, clinical experience, incorporated clinical capability, synthesizing, support required and clinical learning. The final theme of student attitude included the subthemes of individual, technology and course. Without student evaluations, curricular improvements including assessment and clinical experience will not evolve to the best of their potential.

Efficacy and safety of prone positioning for patients with acute respiratory distress syndrome.

This article presents an overview of a literature review on how prone positioning can alleviate pathophysiological changes in ARDS and improve ventilation and perfusion. Improvement of gas exchange, efficiency of oxygenation and lung function are emphasized. Literature on the pathophysiology of ARDS, and the physiological effects of prone positioning on haemodynamics and lung function is examined. There are both advantages and disadvantages in turning a patient from the supine to the prone position. There are also contraindications in rotating between the supine and prone positions. Nevertheless, by rotating patients with ARDS, it is possible to achieve a significant improvement in A-aDO2, decrease shunting, and therefore improve oxygenation without use of expensive, invasive and experimental procedures. Placing patients with ARDS in the prone position can reduce inspiratory oxygen concentrations and peak inspiratory pressures, which minimizes the chance for barotrauma and the iatrogenic effects of hyperventilation oxygen toxicity.

Personality change in dementia.

This study examined the prevalence and nature of personality change in 99 patients with dementia of the Alzheimer type and multi-infarct dementia. Personality was assessed using an informant-rated inventory of the patient's personality before and after the onset of dementia, with the difference equating to a change in personality. Personality characteristics were related to the patients' age and sex, duration of illness, degree of cognitive impairment, the presence of a grasp reflex, and extrapyramidal signs. Personality change was found to be almost universal and negative in nature and was particularly associated with severity of cognitive impairment, longer duration of illness, and neurological signs. The findings reflect those from other studies and emphasize the biological basis of personality changes in dementia.

The cost-effectiveness of ambulatory blood pressure monitoring.

Some people's blood pressure is elevated simply by being in a clinical environment. Twenty-four hour monitoring gives a more accurate average blood pressure reading. The initial costs of ABPM are recouped in less than two years.

The utility of the Philips SRI-100 Real Time Portal Imaging Device in a case of postoperative irradiation for prevention of heterotopic bone formation following total hip replacement.

The new Radiation Oncology Department at the Heidelberg Repatriation Hospital in Melbourne, Australia commenced operation in June 1992. As part of quality control the Philips SL-15 linear accelerator was fitted with the Philips SRI-100 Real Time Portal Imaging Device (RTPID), the first such apparatus in Australia. One of its major advantages over older systems is its ability to provide a permanent hard copy of the image of the field treated. The computer image can be immediately manipulated and enhanced on the screen (with respect to such qualities as brightness and contrast) prior to the printing of the hard copy. This is a significant improvement over the more cumbersome older port films that required developing time, without any pre-assessment of the image quality. The utility of the Philips SRI-100 RTPID is demonstrated in the case of a patient irradiated soon after total hip replacement, as prophylaxis against heterotopic bone formation (HBF). The rapidity and quality of image production is a major advantage in these patients where post-operative pain may result in positional change between film exposure and image production. Extremely accurate shielding block position is essential to shield the prosthesis (and allow bone ingrowth for fixation) whilst avoiding inadvertent shielding of the areas at risk for HBF. A review of the literature is provided.
