Checking Accuracy of Hematological and Biochemical Tests of Blood Samples Taken from Venous Catheter Infusion Fluids after Stop Infusion Fluids for a Minute

摘要

The most common method of blood sampling is vein puncture.Therefore, according to the vein puncture technique is invasive and painful,This question is still raised whether intravenous lines can be used for sampling blood~R Therefore, this study was carried out with the aim of determining and comparing the experimental values of complete blood cell count and biochemical through taking blood samples from peripheral vein infusion line and routine blood sampling procedure. This quasi-experimental intervention study was done on 60patients hospitalized in the internal medicine ward who were selected for blood sampling.Two samples were taken from each patient through peripheral intravenous line after stopped infusion fluid of peripheral catheter(case)for one minute and through the routine blood sampling procedure (control).Then all the samples were analyzed in terms of the number of white blood cells, red blood cells, platelets,hemoglobin .Hematocrit,sodium,potassium,urea and creatinin using SPSS softwarel9,paired t-test and Pearson correlation. Differences of hemoglobin and hematocrit contents.sodium and potassium through IVand vein puncture methods were significant. It can be used to blood samples taken from a peripheral vein infusion line in order tomeasuring the amount of white blood cells,red blood cells,platelets,urea and creatinin levels after stopping one minute of flow infusion in vulnerable patients.
