The day at the Hospital: The first patient arrived at 08:00, when the daily clinical meeting for the trauma admissions began. During the first hour, an effort was made in order to triage victims and organize the requirements for operating room and ICU treatment. All scheduled operations were aborted and six orthopaedic trauma teams were prepared to start operations immediately. A separate area in the Hospital was established to treat minor injuries. All patients were operated within the first 8 hours. Injury characteristics: 39 patients admitted with an ISS higher than 9 presented the most severe injuries. A study group was made with these patients. Mean age were 33,6. The mean RTS were 6,87, mean ISS 21,94, and mean NISS 26,15, revealing the high frequency of multisistemic injuries. The most frequently injury in these group were pulmonary blast injury, with a mean AIS for thorax of 2,7 points.74% of patients had some type of pulmonary blast injury. Limb injuries: 12 (25%) patients had open fractures, combined in all cases with pulmonary blast. Open Gustilo IIIb and IIIc occur in seven patients. Soft tissue injuries caused by small fragments were also frequent. Two patients presented SCIWORA like injuries of the thoracic medullary cord. All patients were operated in the first six hours after the explosion. A detailed description of the injuries, treatment and functional outcome will be presented. Functional outcome were analyzed by physical and psychological scales at six and twelve months after the attack. Scales used were SF-36(short form 36), EQ-5D (Euroqol), CES-D( Center for Epidemiologic Studies Depression Scale) and AVS. Comparison with a similar general trauma group revealed poorer functional outcome at six months for the study group.
