Abstract

Abstract: Objective

To investigate the early diagnosis significance of immature granulocyte (IG) in patients with sepsis.

Methods

A total of 185 in patients with suspected sepsis in our hospital between January 2008 and June 2013 were enrolled. Their relative data were analyzed retrospectively. The blood culture and peripheral blood IG warning flag results were analyzed statistically.

Results

Among the 185 cases, there were 134 cases of blood culture positive. There were IG ≤0.50% (7 cases), IG ≤3.00% (32 cases), IG ≤4.00% (65 cases) and IG >4.00% (30 cases). Blood culture negative had 51 cases in the 185 cases, and IG ≤0.50% (26 cases), IG ≤3.00% (17 cases), IG ≤4.00% (5 cases) and IG >4.00% (3 cases). It was significant between IG >3.00% group and the other groups(P<0.05), when the results of blood culture was positive. It was significant between IG ≤3.00% group and the other groups(P<0.05), when the results of blood culture was negative.

Conclusions

The results of IG >3.00% can be used as a early auxiliary diagnosis index for patients with sepsis. It has specificity in the diagnosis of sepsis.
