Hyperbaric oxygen therapy for severe blast injury of lower extremity after terrorist attack: case report

More blast injuries are encountered in the civilian setting in recent years as terrorist attacks have increased globally. A 17-year-old male patient with severe blast injury of the right lower extremity was admitted to our department on the fifth day after a terrorist bombing attack. Initially he had been admitted to an emergency department with segmental tibia fracture and arterial injury (Gustilo IIIC). An amputation had been foreseen due to ischemia that persisted even after orthopedic fixation and revascularization interventions, followed by fasciotomy incisions. After consultation with our department hyperbaric oxygen (HBO2) therapy was administered twice daily for the first week. Ischemia improved prominently after 10 HBO2 sessions. HBO2 therapy was continued together with antibiotherapy and wound care. The patient underwent a total of 40 HBO2 sessions and two reconstructive operations and healed without amputation. Vascular injuries with concomitant orthopedic trauma cause most of the delayed amputations in bombing attacks since ischemia can persist at the microvascular level even though adequate treatments are applied. HBO2 corrects hypoxia at tissue level and so provides oxygen for the critically ischemic cells in the injured area. HBO2 also enhances host defense and decreases the ischemia reperfusion injury. In this case, HBO2 was effective in survival and functional recovery (salvage) of the extremity together with regular wound care, antibiotherapy and surgical repair.
