ICU nurses have an important role in preparing and controlling the blood glucose sample. Due to the lack of evidence for appropriateness of measuring blood glucose in patients with hemodynamic instability using glucometers, the current study aimed to compare the glucometry results with venous blood sugar in diabetic patients undergoing open heart surgery with hemodynamic instability. Instrument & Methods: In this comparative study with a time-series design, which was conducted in the heart surgery and ICU wards of Vali-Asr hospital of Birjand in 2015, 60 diabetic patients were selected based on convenience sampling method. Blood glucose samples were measured through venous blood sampling and simultaneously with glucometry method at four stages (before surgery and admission to the operating room, opening time of the thorax, admission in the ICU, and one hour after admission to the ICU). The data were analyzed with SPSS 16 software, using Pearson correlation test, repeated measures analysis and Bland and Altman’s charts. Findings: There was a significant difference between glucometry blood glucose average with venous blood glucose at all four sampling occasions (p<0.001). Bland and Altman’s chart showed difference between two methods. There was a strong correlation between two measuring methods of blood sugar (p<0.001; r=0.94). Conclusion: It seems inappropriate to measure blood sugar in patients with hemodynamic instability via the glucometry method and venous blood sampling seems more reasonable. }, URL = {http://imtj.gmu.ac.ir/article-1-2465-en.html}, eprint = {http://imtj.gmu.ac.ir/article-1-2465-en.pdf}, journal = {Internal Medicine Today}, doi = {10.18869/acadpub.hms.23.1.1}, year = {2017} }
