To determine if a dry fibrin sealant dressing (DFSD) will provide superior hemostasis when compared with regular gauze in a ballistic injury animal model.
A nonsurvival randomized goat study.
A federal biomedical research institute.
Eighteen anesthetized Angora goats.
Uncontrolled hemorrhage was induced by a complex ballistic extremity injury. Control of hemorrhage was achieved by applying and holding pressure with the DFSD or regular gauze for 2 minutes. The dressings were left in place for 1 hour.
Main Outcome Measures
Total blood loss, mean arterial pressure, ballistic injury, and mortality were recorded after 1 hour.
The injuries were equivalent for the 2 groups. No animal mortality was seen. After 1 hour, the mean(±SEM) blood loss was 124±64 mL in the DFSD-treated group and 377±64 mL in the gauze dressings–treated group (P=.01). Twenty minutes after injury, the mean arterial pressure was 95.0 mm Hg (±SEM, ±4.7 mm Hg) in the DFSD-treated group and 70.0±5.0 mm Hg in the gauze dressings–treated group. The difference persisted for the remainder of the study (P=.01).
The DFSD was superior to gauze in decreasing blood loss and maintaining blood pressure while retaining the simplicity of standard dressing application.
