Abstract:
Objective To observe the correlation between CD64 index levels in peripheral blood and the severity and prognosis factors of postoperative traumatic sepsis,and investigate the clinical effect of these changes in the development of postoperative traumatic sepsis.Methods A total of 560 patients with trauma were enrolled in the study,and these patients were divided into the postoperative traumatic sepsis group (210 cases) and the postoperative general trauma group (350 cases) according to clinical manifestations.According to the severity of the postoperative traumatic sepsis,these patients were divided into low-risk group (64 cases),moderate-risk group (75 cases) and high-risk group (71 cases).According to clinical prognosis,these patients with post-traumatic sepsis were divided into survival group (178 cases) and death group (32 cases).The CD64 index in peripheral blood and APACHE Ⅱ score were analyzed and measured by flow cytometry.The differences and correlation between CD64 index levels and APACHE Ⅱ score were compared and analyzed,and the relationship between CD64 index levels and the severity and prognosis of postoperative traumatic sepsis were also assessed.Results The CD64 index levels of postoperative traumatic sepsis group were higher than the postoperative general trauma group (P<0.05).The differences in terms of CD64 index,APACHE Ⅱ score and mortality rate among low-risk group,moderate-risk group and high-risk group were statistically significant,in which high-risk group was the highest,followed by moderate-risk group,and low-risk group was the lowest(P<0.05).Compared with the survival group,the death group had higher CD64 index levels and APACHE Ⅱ score (P<0.05).The CD64 index levels were positive correlated with APACHE Ⅱ score (r=0.72,P=0.00) and mortality (r=0.56,P=0.00).ROC curves analysis results showed that the area under curve of CD64 index was 0.874 (95%CI:0.765~0.896), and the optimal operating point was 7.08,which had 82.6% sensiticity and 86.4% specificity.Conclusion The increased CD64 index levels in postoperative traumatic sepsis are closely related to the severity and prognosis of disease,and the CD64 index levels can be effective predictor with some clinical application value.
