Summary
High-pressure injection injuries, though serious, may have better outcomes than previously thought. Latex-based paints are associated with lower amputation rates and fewer complications compared to grease or oil-based paints.
Area of Science:
- Trauma surgery
- Orthopedics
- Emergency medicine
Background:
- High-pressure injection injuries (HPIIs) are rare but severe traumas.
- Historically, HPIIs have been linked to high rates of limb amputation.
Purpose of the Study:
- To evaluate amputation rates, common materials involved, and patient outcomes for HPIIs.
- To reassess the prognosis of HPIIs based on contemporary data.
Main Methods:
- Retrospective analysis of 53 HPII cases from 2007-2023.
- Data collected included demographics, injury specifics, injected materials, surgical treatments, and follow-up outcomes.
- Level-1 trauma center setting.
Main Results:
- The overall amputation rate was 2.2%.
- Latex-based paints were associated with more favorable outcomes than grease or oil-based paints.
- Fewer reoperations and postoperative complications were observed with latex-based paint injuries.
Conclusions:
- HPII prognosis may be more optimistic than historically reported.
- The evolution of injected materials, particularly latex-based paints, may contribute to lower amputation rates.
- Re-evaluation of HPII outcomes is warranted.
