Is there an association between inflammatory biomarkers and organ space surgical site infection after emergency laparotomy in massively transfused trauma patients?

BACKGROUND

The relationship between inflammatory biomarkers (IB) and organ space surgical site infections (OS-SSIs) after emergency laparotomy (EL) is poorly understood.

METHODS

Retrospective, single-center analysis of patients in the Pragmatic, Randomized Optimal Platelet and Plasma Ratios (PROPPR) trial who underwent EL and survived 48 ​h after admission was performed. IB levels of IL-6, IL-8, G-CSF, MCP-1, neutrophil to lymphocyte ratio, and platelet to lymphocyte ratio were analyzed. IB and OS-SSIs association was evaluated using the Wilcoxon rank sum test.

RESULTS

Of 74 eligible patients, 80 ​% were male, 69 ​% sustained blunt trauma, the injury severity score was 31 (24-41), and 22 ​% developed OS-SSIs. Levels of IL-6 (12, 24 ​h), IL-8 (2, 12, 24, 72 ​h), and MCP-1 (24 ​h) were higher in OS-SSI patients (P ​< ​0.05).

CONCLUSIONS

IL-6, IL-8, and MCP-1 levels were associated with OS-SSIs in PROPPR patients who underwent EL. The IB may help to predict high-risk patients for OS-SSIs.
