Insights
Preperitoneal pelvic packing (PPP) for severe pelvic fractures increases the risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). Vigilant screening for these conditions is crucial in patients undergoing PPP.
Area of Science:
- Trauma Surgery
- Vascular Surgery
- Critical Care Medicine
Background:
- Preperitoneal pelvic packing (PPP) is a critical intervention for managing severe pelvic hemorrhage in blunt trauma.
- The potential association between PPP and venous thromboembolism (VTE) requires further investigation.
Purpose of the Study:
- To investigate the hypothesis that PPP is associated with an increased incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE).
Main Methods:
- Retrospective cohort analysis of blunt trauma patients with severe pelvic fractures (AIS ≥4) from 2015-2017.
- Propensity score matching was used to compare patients who underwent PPP within 4 hours of admission with those who did not.
- Comparison of DVT and PE rates between matched groups.
Main Results:
- Out of 5129 patients, 157 underwent PPP and were matched with 157 controls.
- No significant differences in baseline variables, mortality, or end-organ failure were observed between groups.
- PPP patients had significantly higher rates of DVT (12.7% vs 5.1%) and PE (5.7% vs 0.0%).
Conclusions:
- Preperitoneal pelvic packing for severe pelvic fractures in blunt trauma is linked to a higher risk of DVT and PE.
- Maintain a high index of suspicion and low threshold for screening for DVT and PE in patients who have undergone PPP.
Introduction:
Preperitoneal pelvic packing (PPP) is an important intervention for control of severe pelvic hemorrhage in blunt trauma patients. We hypothesized that PPP is associated with an increased incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE).
Methods:
A retrospective cohort analysis of blunt trauma patients with severe pelvic fractures (AIS ≥4) using the 2015-2017 American College of Surgeons-Trauma Quality Improvement Program database was performed. Patients who underwent PPP within four hours of admission were matched to patients who did not using propensity score matching. Matching was performed based on demographics, comorbidities, injury- and resuscitation-related parameters, vital signs at presentation, and initiation and type of prophylactic anticoagulation. The rates of DVT and PE were compared between the matched groups.
Results:
Out of 5129 patients with severe pelvic fractures, 157 (3.1%) underwent PPP within four h of presentation and were matched with 157 who did not. No significant differences were detected between the two matched groups in any of the examined baseline variables. Similarly, mortality and end-organ failure rates were not different. However, PPP patients were significantly more likely to develop DVT (12.7% versus 5.1%, P = 0.028) and PE (5.7% versus 0.0%, P = 0.003).
Conclusions:
PPP in severe pelvic fractures secondary to blunt trauma is associated with an increased risk of DVT and PE. A high index of suspicion and a low threshold for screening for these conditions should be maintained in patients who undergo PPP.
