PENGARUH WAKTU PELEPASAN TOURNIQUET TERHADAP KADAR KALIUM PADA PENGAMBILAN DARAH VENA

Tourniquet can be a problem if it is tied too long and too tightly when taking venous blood can affect potassium levels and result in high false potassium levels (pseudohiperkalemia). This study aims to determine the effect of Tourniquet release time on potassium levels in venous blood collection. This study uses the Quasy Experiment method using a Non-Equivalent Control group design involving two groups with two different treatments. The variables of this study were the time of tourniquet release and potassium levels. Data processing in this study was conducted in univariate and bivariate. Analysis of the data in this study also used the Independent T Test to determine the effect between variables.The results of the study through statistical analysis showed that the average blood potassium level in the first group was 3.784 mEq / L and the second group was 4.896 mEq / L. From the results of statistical tests obtained a value of P value (0,000) <α (0.05) which means Ha is accepted so that the results of this study are there are differences in the average potassium levels at the moment of release of tourniquet blood entering and releasing the tourniquet after blood. The conclusion of this study is that the release time of the tourniquet can affect potassium levels and it is recommended for medical personnel to release the tourniquet while the blood enters the syringe needle when taking venous blood to avoid high levels of potassium in the serum.Keywords: Tourniquet Release, Potassium Levels, and Pseudohiperkalemia
