Effectiveness of exclusive self-monitoring of fasting capillary blood glucose in the treatment of diabetes/Analise da eficacia do automonitoramento exclusivo de glicemia capilar de jejum no tratamento da diabetes

The study aims to analyze the efficacy of the exclusive self-monitoring of the fasting capillary blood glucose in the control and treatment of diabetic patients. This is a quasi-experimental study, for which five individuals with diabetes were selected, who perform only the fasting capillary blood glucose monitoring, being added about seven other measurements, a variable number according to the individual availability of the volunteer, at different times throughout the day. It was verified that four individuals presented blood glucose values by the use of the fasting capillary blood glucose monitoring, within the parameters of normality for diabetics, between 70-130 mg d[L.sup.-1] of blood (ADA, 2014b), although in the other measurements, they presented values far from the ideal goal, in a significant part of the time. The study outlines a trend that shows that the glycemic monitoring values based solely on the fasting capillary blood glucose is ineffective, since they can erroneously indicate satisfactory control of the blood glucose levels. Based on the results obtained, to a more effective monitoring and which denotes levels of reliability, it is required at least three measurements of capillary blood glucose throughout the day, and also, the importance of long laboratory tests for glycemic monitoring, such as glycated hemoglobin.

O objetivo deste estudo e analisar a eficacia do automonitoramento exclusivo da glicemia capilar de jejum no controle e no tratamento de pacientes diabeticos. Trata-se de um estudo quase experimental, para o qual foram selecionados cinco individuos portadores de diabetes que realizam apenas o monitoramento da glicemia capilar de jejum e acrescentaram cerca de outras sete medicoes, numero variavel de acordo com a disponibilidade individual do voluntario, em diferentes horarios ao longo do dia. Verificou-se que quatro individuos apresentaram os valores glicemicos pelo monitoramento da glicemia capilar de jejum dentro dos parametros de normalidade para os diabeticos, entre 70-130 mg d[L.sup.-1] de sangue (ADA, 2014b), apesar de nas outras medicoes apresentarem, em parte significativa das vezes, valores fora da meta ideal. Logo, o estudo traca uma tendencia que mostra que o acompanhamento glicemico baseado exclusivamente nos valores de glicemia capilar de jejum e ineficaz, uma vez que pode erroneamente indicar controle satisfatorio dos
