Objectives: Severe pelvic fracture concomitant with massive bleeding is potentially lethal, and intervention for hemorrhage control still depends on institutional supplies. With the recent installation of a CT and C-arm combined resuscitation room system (CTCARM) for treatment of trauma patients in our institution, the strategic process and options for hemorrhage control after pelvic fracture have changed. We retrospectively reviewed the procedures we performed and their outcomes.
Methods: The CTCARM was installed in our trauma resuscitation room in April 2020. Patients who were diagnosed as having pelvic fracture and underwent interventional radiology for hemorrhage control within 2.5 hours after arrival were compared before and after CTCARM installation. We reviewed the time process for hemorrhage control, treatment options performed, blood products used and their outcomes.
Results: Included in this study were 56 patients treated between 2016 and 2022, of whom 36 patients were treated before (original group) and 20 patients after CTCARM installation (CTCARM group). Patient characteristics and vital signs at admission were not statistically different. Preperitoneal pelvic packing was performed significantly more frequently in the original group (p<0.01), whereas resuscitative endovascular balloon occlusion of the aorta use was much more frequent in the CTCARM group (p=0.02). Although the times from admission to first angiography (p=0.014) and to complete hemostasis (p=0.02) were significantly shorter in the CTCARM group, mortality was not statistically different. Four preventable trauma deaths occurred in the original group, but there were none in the CTCARM group. Six unexpected survivors were observed in the original group and four in the CTCARM group.
Conclusions: Although the CTCARM had no direct effects on patient mortality for now, it has allowed us to accelerate the treatment time process, shorten preperitoneal pelvic packing procedural time, and potentially avoid subsequent preventable trauma deaths.
