Özet
Background: The aim of this study is to reveal the relationship between end-tidal CO2 (EtCO2) values with infarct volume and early prognosis in patients diagnosed with acute ischemic stroke in the emergency department. Materials and Methods: This prospective cross-sectional study was conducted in a tertiary hospital. The demographics, characteristics, EtCO2, volume of the stroke area on diffusion-weighted magnetic resonance imaging and the modified Rankin Scale (mRS) of the patients were recorded. The values calculated at admission and at discharge were labeled as mRS-1 and mRS-2, respectively, and the mRS-2 measurement was used as a prognostic indicator. The good and the poor functional outcomes were defined as mRS <= 2 and mRS >2, respectively. Correlations between levels of EtCO2 and infarct volume, mRS were calculated. Results: In total, 44 patients were included in the study. The median age of the patients was 69 years (interquartile range; 16; min-max: 35 to 88 y) and 68.2% of them were male. In the univariate logistic regression models of the mRS-2 [0 to 2 (0) and 3 to 6 (1)], all variables were not statistically significant to predict mRS-2 group. There were statistically significant differences in EtCO2 values between mRS-1 (P=0.03) and mRS-2 (P=0.04). A negative moderate correlation was found between EtCO2 and mRS-2 (r=-0.410; P=0.006). The correlation between EtCO2 and infarct volume was not statistically significant (r=-0.256; P=0.093). Conclusions: This study highlights the importance of capnography follow-up of patients with acute ischemic stroke. In patients with acute ischemic stroke, the EtCO2 value measured at the time of admission is lower in the group with high mRS at both admission and discharge.
