ABSTRACT
Objective To explore the clinical value of Dynamic testing of serum cortisol (COR) and procalcitonin (PCT) in the prediction and prognosis of sepsis after burn.Methods 122adult patients with severe burns who were treated by our unit from September 2014to November 2017were selected and retrospective analyzed.According to the diagnosis criteria of sepsis and the prognosis, the patients were divided into nonsepsis group, sepsis survival group and sepsis death group.The serum COR and PCT level in 1-20days after burn were continuously and dynamically monitored and measured using an automated electrochemical method and immunofluorescence method respectively.Results The serum COR levels in sepsis patients were significantly higher than those in non-sepsis group from the sixth day after burns (P<0.05) , and the serum PCT levels were significantly higher than those in the non-sepsis group from the 7th day after burn (P<0.05) .From the 11th day after burn, the serum COR and PCT levels in the sepsis death group were significantly higher than those in the sepsis survival group (P<0.05);the serum PCT levels in the sepsis death group were significantly higher than those in the sepsis survival group from the 15th day after the burn (P<0.05) .The serum COR levels in the sepsis-dead group decreased linearly, and the serum COR levels were significantly lower than those in the sepsis survival group (P<0.05) .Conclusion The combined testing of serum COR and PCT can be used as an early predictor of post burn sepsis, The Dynamic testing of serum COR and PCT levels in the important clinical application value in the evaluation of prognosis of sepsis after burn.
