Blast injuries: The experience of a level 1 trauma center.

Background: There is a global surge in blast injuries, which are associated with high morbidity and mortality. To our knowledge, there are no guidelines for the management of blast injuries in the trauma bay.

Methods: This single-center retrospective cohort study utilized data on all patients admitted to our emergency department (ED) with terror- or combat-related injuries between October 7, 2023 (Gaza Iron Swords War onset) and February 4, 2024. The primary outcome was trauma severity indicated by either an injury severity score (ISS) >15 and/or need for acute care. We also analyzed the mechanisms of injuries, focusing on those resulting from blasts.

Results: Of 208 patients who were admitted following terror-and combat related injuries, 109 patients (101 males [93 %], median age 24.0 years) were admitted following blast injuries. Of them, 88 % were military personnel and 12 % were civilians, with a median ISS of 8 [IQR:4.0-17.0]. The level of trauma was severe in 48 patients (44 %). Tertiary sub-category of blast injuries (P =0.004), chest (P =0.032), abdomen (P =0.018), and lower extremities (P =0.044) injuries were significantly associated with severe trauma. Blast injuries mandated the urgent availability of specialist personnel and appropriate equipment to contend with multiple life-threatening sequelae of exposure to blasts upon the arrival of the victims to emergency services.

Conclusion: Blast injuries present unique challenges in management and demand a multidisciplinary approach and specialized resources. We present an algorithm for terror- and combat-related blast injuries treated in our trauma bay. The step-by-step procedures may be applicable to any blast injury sustained under variable conditions.
