Infusion thrombophlebitis and infection with various cannulas.

A prospective study was carried out of the frequency of thrombophlebitis and bacterial contamination of cannulas associated with four commonly used intravenous cannulas of differing length and chemical composition. For all cannulas the frequency of thrombophlebitis increased significantly with time. Long 'Teflon' cannulas were significantly more likely to be contaminated with bacteria and associated with thrombophlebitis than all other cannulas, while the low frequency of thrombophlebitis with butterfly stainless steel cannulas was shown to be due to their short duration of use. It is suggested that long teflon cannulas should be avoided and that infusion thrombophlebitis could be eliminated as a clinical problem by the use of intermittent short duration intravenous infusions.

Effect of a Millipore filter on complications of intravenous infusions: a prospective clinical trial.

The Millipore filter unit has been advocated as a means of reducing the chance of bacteria entering the circulation during intravenous infusion. In a prospective study no significant reduction was obtained in the incidence of thrombophlebitis or in the bacterial contamination of cannulae. The unit was inconvenient to use and in-vitro and in-vivo studies showed reduced flow rates and frequent episodes of filter blockage. Its use was further restricted by the fact that blood and fat emulsions would not pass through it.

Effect of retrograde electrical pacing on jejunal absorption of xylose and vitamin C.

Does retrograde electrical pacing of a continuously perfused jejunal segment increase absorption of xylose and vitamin C? Proximal jejunal segments (75 cm) were isolated from the intestinal stream in 5 dogs, and recording and stimulating electrodes attached. A solution containing 139.9 mmol/liter xylose, 0.57 mmol/liter vitamin C, and 79.9 mmol/liter sodium chloride was infused into the loop at a rate of 2.8 ml/min. Effluent from the loop was collected in 5-min aliquots during 3 consecutive periods of 30 min, and the composition of each analyzed. During the second period, when retrograde electrical pacing was performed, there was a significant decrease in water, xylose, and vitamin C output (p less than 0.0001).

Integration of midwives into the Quebec health care system. L'Equipe d'Evaluation des Projets-Pilotes Sages-Femmes.

This paper reports on one aspect of the evaluation of the midwifery pilot projects in Quebec: the identification of the professional and organizational factors, as well as the mode of integrating midwives into the maternity care system, that would promote the best outcomes and the autonomy of midwives. The research strategy involved a multiple-case study, in which each midwifery pilot project represented a case. Based on a qualitative approach, the study employed various sources of data: individual interviews and focus groups with key informants, site observations and analyses of written documents. Results show that midwives were poorly integrated into the health care system during the evaluation. Four main reasons were identified: lack of knowledge about the practice of midwifery on the part of other health care providers; deficiencies in the legal and organizational structure of the pilot projects; competition over professional territories; and gaps between the midwives' and other providers' professional cultures. Recommendations are provided to facilitate the integration of midwives into the health care system.

A proposal for a precise definition of abdominal aortic aneurysm. A personal view.

Recent advances in Vascular Surgical practice have highlighted the urgent need for a precise internationally agreed definition of what an abdominal aortic aneurysm is. After consideration of possible alternatives a proposal is made that "An abdominal aortic aneurysm is present when the maximum external diameter of the infrarenal abdominal aorta is either (1) greater than 4.0 cm or (2) exceeds the maximum diameter of the aorta between the origin of the superior mesenteric and left renal arteries by at least 0.5 cm". An international nomenclature congress may be required to produce a universally agreed definition.
