RESUMO
La punción arterial es un procedimiento al que pacientes y enfermeros se enfrentan con recelo por el dolor que produce. Evaluamos la efectividad de un nuevo protocolo de punción arterial con aguja fina (paf) menos doloroso y lesivo. Se aplica un diseño randomizado comparativo para muestras independientes sobre pacientes a los que se solicita muestra de sangre arterial. Análisis de las variables intensidad de dolor, dolor comparado y dificultad técnica. Existe una confirmación muy significativa de la hipótesis alternativa a favor de menores índices de dolor y dificultad técnica con paf arterial. Una versión más amplia de este trabajo obtuvo premio en el certamen de investigación Ciudad de Sevilla(AU)
The arterial puncture is a procedure that patients and nurses are faced with suspicion by the pain it causes. We evaluate the effectiveness of a new protocol of arterial puncture with fine needle (paf) less painful and damaging. Comparative randomized design for independent samples on patients who request samples of arterial blood. Analysis of the variables of pain intensity, compared pain and technical difficulty. Significant confirmation of the alternative hypothesis in favor of lower rates of pain and technical difficulty with paf(AU)

With the objective to carry out a quality control check on the storage of arterial blood samples in order to take postponed gasometric measurements, the authors designed an experimental comparative study of paired blood samples, one in refrigerated plastic syringes and the other kept at room temperature to study the effectiveness or not of refrigerating this type of syringes. The results obtained in this study contradict the rules of protocols currently in use since these results, advise against the refrigeration of this material since that produces a significant increase in the values of partial oxygen pressure. However, the changes in pH and pCO2 do not show any significant statistical importance. The authors provide an explanation to this phenomenon and they recommend that working protocols be corrected to not refrigerate blood samples if these are taken with common plastic, polypropylene, syringes.
