[Concordance among samples taken from a subcutaneous reservoir and a peripheral puncture]. / Concordancia entre muestras extraídas por reservorio subcutáneo y punción periférica.

Many patients who undergo phlebo-toxic treatment eventually require central vein access ways and of these accesses, the most common one used among oncology patients due to its advantages is a subcutaneous reservoir. The objective of this study was to verify the concordance among samples obtained from a subcutaneous reservoir using the rejection technique, and those obtained when using a direct puncture technique. This study included 22 patients who were carriers of a subcutaneous reservoir and who visited outpatient services during March and April in 2006. The study authors obtained simultaneous samples from subcutaneous reservoirs and from peripheral veins. These parameters were compared by means of an intra-class correlation coefficient. Only hematology parameters, that is leucocytes, hematocrits, hemoglobin and platelets, showed an adequate concordance.

Concordancia entre muestras extraídas por reservorio subcutáneo y punción periférica / Concordance among simples taken from a subcutaneous reservoir and a peripheral puncture

Muchos de los pacientes que reciben tratamientos flebotóxicos acaban precisando accesos venosos centrales siendo el más común por sus ventajas, entre los pacientes oncológicos, el reservorio subcutáneo. El objetivo de este estudio fue averiguar la concordancia entre las muestras obtenidas del reservorio subcutáneo, utilizando la técnica de descarte, y las obtenidas por punción directa. La muestra incluía 22 pacientes portadores de reservorios subcutáneos, que acudieron al hospital de día durante los meses de marzo y abril del 2006. Se obtuvieron muestras simultáneas del reservorio subcutáneo y de vena periférica. Los parámetros se compararon con el coeficiente de correlación intraclase. Sólo los parámetros de hematología (leucocitos, hematocrito, hemoglobina y plaquetas) obtuvieron una concordancia adecuada(AU)
