Abstract: Abstract:Objective To discuss changes of accompanying femoral artery and vein blood gas in patients with burn sep⁃ sis. Methods The retrospective data of twenty-two patients with burn sepsis and forty-three non-sepsis patients (control) was analyzed, and changes of accompanying femoral artery and vein blood gas were compared between two groups.Results Results of femoral artery gas analysis showed that the HCO3- concentration was lower in sepsis group than that of control group. Results of femoral vein blood gas showed that the partial pressure of carbon dioxide [p(CO2)] was higher in sepsis group than that of control group; the oxygen saturation (SvO2) and HCO3- concentration was lower in sepsis group than that of control group (P＜ 0.01). The differences between oxygen partial pressure p(O2), p(CO2), HCO3- concentration, oxygen satura⁃ tion of femoral artery and vein blood gas were significantly higher in sepsis group than those of control group (P＜ 0.01). Conclusion Results of femoral vein blood gas analysis change obviously in patients with burn sepsis . The detection of accompanying femoral artery and vein blood gas is beneficial to diagnosis of burn sepsis.
