Abstract
Los pacientes críticos se ven sometidos a múltiples extracciones de sangre de un catéter para analítica, siendo necesario desechar un volumen de sangre adecuado, que evite alteraciones en los resultados, secundarias a las perfusiones que se administran por los mismos. En las unidades de cuidados intensivos los procedimientos invasivos se consideran estímulos que actúan de manera negativa sobre los pacientes, y producen cambios en una variedad de parámetros psico-fisiológicos, siendo frecuente que los pacientes se vean sometidos a varias determinaciones analíticas diarias. En algunos casos la situación de los pacientes o la medicación que se administra, puede hacer difícil o desaconsejable la punción directa de venas periféricas para la obtención de la muestra necesaria. Punciones evitables por otra parte, si realizamos la extracción directamente desde un catéter ya implantado. Para realizar la extracción desde un catéter, es necesario desechar un volumen de sangre adecuado, que evite alteraciones en los resultados, secundarias a las perfusiones que se administran. Nuestro objetivo fue determinar la fiabilidad de los parámetros analíticos tras desechar dos cc de sangre de la luz proximal del catéter venoso central de tres luces, frente a la punción directa, sin parar las perfusiones de la luz media y distal y sin lavado previo...
Patients admitted to an intensive care unit are subjected to numerous invasive procedures for both diagnostic and therapeutic purposes. One of the most frequent invasive procedures is blood collection by venous puncture for biochemical, haematological and coagulation tests. Invasive procedures in intensive care units (ICUs) are thought to negatively affect patients psychologically, who often have to undergo several daily tests. In some cases, the patient's state or medication make it not recommendable to subject them to the direct puncture of a peripheral vein to obtain the necessary sample. This may be avoided by collecting blood from an indwelling catheter. When drawing blood in this manner, an adequate volume of blood is usually discarded to avoid altering test results due to the presence of infusion substances. The present study sought to examine the reliability of biochemistry, blood cell count and coagulation variables determined in blood samples obtained in ICU patients from the proximal lumen of a triple-lumen CVC using a 2 mL discard volume without prior flushing or interrupting infusion through the other lumens...
