Introduction: Angioembolization is a life-saving intervention for hemorrhage control after traumatic hemorrhage and is frequently employed in selective non-operative management of solid organ injuries. We examined the risk factors of for mortality after angioembolization in traumatic hemorrhagic shock.
Methods: The Glue Grant database was analyzed. Patients who had angioembolization were included. Survivors were compared with non-survivors. Univariate and multivariable analyses were used to determine predictors or mortality.
Results: A total of 258 patients were included with a mean age of 44 years. Compared to non-survivors, survivors were slightly younger (42±19 vs. 51±20, p=0.004), had lower multiple organ dysfunction score (6±2 vs. 9±3, p<0.0001), lower Injury Severity Score (38±13 vs. 44±16, p=0.003), lower ER lactate (4.5±2.8 vs. 6.6±3.5, p<0.001), and received less blood (2889±2357 vs. 8232±6619, p<0.001) and crystalloids (10756±5272 vs. 16561±10083, p<0.001). Predictors of mortality include age (OR: 1.045, CI: 1.022-1.070, p<0.001), multiple organ dysfunction score (OR: 1.584, CI: 1.302-1.927, p<0.001), ER lactate (OR: 1.177 , CI: 1.031-1.343, p=0.016) and cardiac arrest (OR: 37.185, CI: 7.948-173.976, p<0.001). p=0.002)
Conclusion: Age. Multiple organ dysfunction, ER lactate level, and cardiac arrest are independently associated with mortality following traumatic hemorrhagic shock.
