o bien rea lizando una punción en la yema de los dedos para conseguir una gota de sangre, depositándose esta en una tirita reactiva donde se mide la glucemia. or by performing a puncture on the fingertips to get a drop of blood, depositing it in a test strip where blood glucose is measured.
Estos métodos dan una medida en un momento concreto, pero no son ideales para valorar la diabetes, ya que tendría que hacerse una curva de glucemia a base de tomar muestras de sangre cada veinte minutos, (muchas veces al día), lo cual es incomodo y doloroso, sobre todo para los niños, debido al endurecimiento de la piel de la yema de los dedos por culpa de las punciones, además que en la práctica no se puede desarrollar todos los días. These methods give a measure at a specific time, but they are not ideal for assessing diabetes, since a blood glucose curve should be done based on taking blood samples every twenty minutes, (many times a day), which is uncomfortable and painful, especially for children, due to the hardening of the skin of the fingertips because of the punctures, in addition that in practice it cannot develop every day.
Además, si surgen complicaciones en el caso de aparecer una alteración cuantitativa del valor de la glucemia, obligaria a pedir cita en el ambulatorio, con la demora correspondiente. In addition, if complications arise in the case of a quantitative alteration of the glycemic value, it would be necessary to make an appointment in the outpatient clinic, with the corresponding delay.
Por otro lado, independientemente de la frecuencia de toma de sangre, hay que tener en cuenta la correlación de los valores de la curva de glucemia con el modo de vida, la actividad que se esta desarrollando, la alimentación, la medicación, etc, para poder fijar exactamente el tratamiento-pronóstico. On the other hand, regardless of the frequency of blood collection, it is necessary to take into account the correlation of the values of the blood glucose curve with the way of life, the activity that is being developed, the feeding, the medication, etc., to be able to fix the prognostic treatment exactly.
