Purpose: Mechanical ventilation (MV) is an essential life-saving modality for severely injured patients. However, the long-term use of MV is a major risk factor for late mortality. The surgical correction of long bone fractures plays a critical role not only in improving functional outcomes, but also in reducing physiological derangements, including MV duration. This study investigated the factors affecting prolonged MV (PMV) in severely injured patients with femur fractures.
Methods: We retrospectively evaluated all severely injured patients (injury severity score >15) with femur fractures who were taken to the emergency department within 12 hours of the causative accidents between January 2016 and December 2018. PMV was defined as MV lasting for ≥7 days. We analyzed the factors affecting PMV.
Results: In total, 35 patients were enrolled and 21 (33.3%) were included in the PMV group. The PMV group required more red blood cell (RBC) transfusions within 7 days RBC (7dRBC) (12.8 vs. 6.8 units; p=0.03) and the time to femur fracture fixation (TFFF) was longer (7.9 vs. 2.7 days; p=0.018). The area under the curve (AUC) for TFFF was 0.740 (95% confidence interval [CI]: 0.572?0.908; p=0.018) and the AUC for 7dRBC was 0.718 (95% CI: 0.546?0.889; p=0.031).
Conclusions: This study i ndicates that TFFF is an i ndependent risk factor for PMV. Early fixation of femur fractures might prevent PMV and its associated complications.
