An exploration of the role of the nurses'' uniform through a period of non-uniform wear on an acute medical ward

The nursing staff on an acute medical hospital ward elected to wear their own clothes to work for a period of 2 months. The trial was evaluated using a variety of research methods and it raised a number of issues about the role of uniform, about patients' perceptions of nurses and nurses' perceptions of their role. The study has led to questions being raised about the assumptions that are made if uniform is worn and the appropriateness of a uniform dress.     

Chemotherapy-induced nausea

The rubric complementary medicine covers a variety of approaches that may seem alike only in their being outside conventional care and training. We have asked experienced practitioners to present their own pieces of this jigsaw, realising that these clinical fragments, when seen together, create excitement but also confusion. Of course, this forum is not intended to be a comprehensive review of relevant complementary treatments, and often the individual apporaches to clinical problems will appear totally unrelated, while their apparent effectiveness stretches the biomedical model and conventional research methodology beyond their capacity. With this in mind, we intend that forthcoming articles and reviews will expand on the therapies themselves, and discuss the evidence supporting them.     

Controlled reperfusion of the regionally ischemic myocardium with leukocyte-depleted blood reduces stunning, the no-reflow phenomenon, and infarct size.

Open-chest sheep underwent 90 minutes' occlusion of the diagonal branch of the left anterior descending coronary artery, followed by vented cardiopulmonary bypass. After 30 minutes of cardioplegic arrest, simulating distal anastomoses, the occlusion on the coronary artery branch was released. Controlled reperfusion (40 to 50 mm Hg, 135 to 150 ml/min) for the first 20 minutes was delivered at the aortic root with either unmodified whole blood (control, n = 7) or blood passed through leukocyte filters (filters, n = 7). Serial measurements were made during 3 additional hours reperfusion off cardiopulmonary bypass. During ischemia, the major determinants of infarct size, which include area at risk, collateral myocardial blood flow, and rate-pressure product were not significantly different between groups. Overall, during reperfusion, mean left ventricular stroke work index in the filter group was greater than in the control group (28.7 +/- 5.8 versus 12.6 +/- 6.4 x 10(3) erg/gm, p less than 0.05), as was mean rate of rise of left ventricular pressure (1900 +/- 260 versus 1348 +/- 279 mm Hg/sec, p less than 0.05). Myocardial blood flow to the area at risk at 3 1/2 hours of reperfusion in the filter group was also significantly better than in the control group (0.57 +/- 0.15 versus 0.27 +/- 0.05 ml/min/gm, p less than 0.05), as was necrotic area as a percentage of area at risk (40% +/- 6% versus 70% +/- 5%, p less than 0.05). These results demonstrate amelioration of myocardial stunning and the no-reflow phenomenon, as well as decreased infarct size. We conclude that controlled reperfusion with leukocyte-depleted blood is superior to whole-blood reperfusion for the surgical treatment of acute regional ischemia.     

Vaginal cones: a conservative method of treating genuine stress incontinence

Summary. A set of weighted vaginal cones designed to exercise the pelvic floor muscles was used by a group of 39 premenopausal patients with genuine stress incontinence who were awaiting corrective surgery. The effectiveness of the exercises in reducing urinary loss was assessed with a standard urine pad test before and after 1 month of training. Of the 30 women who completed 1 month of the exercises 70% felt they were improved or cured and 90% found it an acceptable method of treatment. Of the 30 women only 11 (37%) opted for surgery after training. There was a highly significant correlation (P<0·001, r_s= -0·21) between decreased urine loss and increase in retained cone weight.
