Introduction:
A number of factors can affect hematological measurements among which the effect of blood sample collection procedures by nurses in hematology test results is of great importance. Therefore, this study was carried out with the aim of determining and comparing the experimental values of complete blood cell count through taking blood samples from peripheral vein infusion of intravenous fluids and routine blood sampling procedure while receiving continuous IV fluids.
Methods & Materials:
This quasi-experimental intervention study was done on 60 patients hospitalized in the internal medicine ward who were selected for blood sampling. Two samples were taken from each patient through a peripheral intravenous line after throwing the first 5 cc of IV away and collecting the remaining 5 cc and through the routine blood sampling procedure for the case and control group, respectively. Then all the samples were analyzed in terms of the number of white blood cells, red blood cells, platelets, hemoglobin and Hematocrit using SPSS software19, paired t-test and Pearson correlation.
Results:
The mean values of white blood cells, red blood cells, platelets, hemoglobin and Hematocrit in the case group were 9694 mm3, 4433000 mm3, 240166 mm3, 12.52 gr/dl, 38.90% and 9587 mm3, 4588000 mm3, 244800 mm3, 12.68 gr/dl, 38.96% in the control group, respectively. A significant difference was only observed in hemoglobin values between the case and control groups.
Conclusion:
In order to measure the amount of white blood cells, red blood cells, platelets and Hematocrit, blood samples taken from peripheral vein infusion can be used after throwing away 5 cc at the beginning of the sampling.
