ABSTRACT

Ten male patients with peripheral vascular disease, Type 2 (LaFontaine), were randomly assigned in a double-blind study to receive either Na2 ethylene diamine tetra acetic acid (EDTA) plus MgSO4, B complex, and vitamin C, or a placebo of MgSO4, B complex, and vitamin C in Ringer's lactate solution. A total of 20 intravenous infusions were planned for administration to each patient. Clinical and laboratory (noninvasive) tests showed dramatic improvements after 10 infusions in some patients, and thus was broken the code indicating who was receiving EDTA and who was receiving placebo. The group that improved had been receiving EDTA; there was no change in the placebo group. The trial was then completed in a single-blind fashion. Patients originally assigned to receive placebo then received 10 EDTA infusions, while the group originally assigned to EDTA received 20 EDTA infusions. The group that had formerly received placebo showed improvements comparable to those seen in the first EDTA group after 10 treatments.

ABSTRACT

Un nuevo monitor automático oscilométrico y noinvasivo de la presión arterial está disponible en el Brasil. El aparato fue evaluado comparando los datos de la presión arterial media con la medida simultánea de la presión arterial por el método directo de cateterización de la arteria radial concectada al manómetro de mercurio. Fueron estudiados 21 niños divididos en dos grupos: grupo 1, constituido por 10 niños con peso menor de 10K, con edad entre 1 mes y 1 año. Grupo 2, constituído por 11 niños con más de 10 Kg, con edad encima de 1 año y 6 meses. El coeficiente de correlación entre las medidas tomadas en los dos grupos fue de r = 0.85 (p < 0,01) para el grupo 1 y r = 0,88 (p < 0,001) para el grupo 2. Se concluyó que las presiones medias fornecidas por el aparato se correlacionan bien con la medida directa de la presión arterial, siendo un instrumento útil para monitorizar presión arterial en niños
