Risk Factors of Fat Embolism Syndrome After Trauma

Background Fat embolism syndrome (FES) is a rare resulting from fat embolism, which defined by the presence of globules in pulmonary microcirculation; it associated with wide range symptoms. Research Question What are specific unknown risk factors for FES after we have controlled basic characteristics and patient’s severity? Study Design Methods This was nested case-control study that used Japan Trauma Data Bank database 2004 2017. We included patients identified without as control subjects using propensity score matching. The primary outcome during hospital stay. Results There were 209 (0.1%) trauma; they compared 2,090 matched 168,835 candidates this study. Patients had long bone open fractures their extremities more frequently than those FES. Regarding treatments, received reduction fixation Among who fixation, time to operation not different between groups (P = .63). overall in-hospital mortality rate 5.8% 3.4% .11). Conditional logistic regression models identify shows injury Primary independently (OR, 1.80; 95% CI, 0.92-3.54), but delay 2.21; 1.16-4.23). Interpretation Long injuries Although FES,
