Background. Fabric-like hemostatic dressings offer promise for hemorrhage control in noncompressible areas, especially given their similarity in form to standard gauze currently in use. Recently, two such products, Combat Gauze (CBG) and TraumaStat (TMS), were introduced. Their performance is evaluated in two vascular injury models.

Materials andMethods. The dressings were evaluated in anesthetized Yorkshire pigs, hemorrhaged by full transection of the femoral vasculature with 2 min free bleeding period (CBG = 6, TMS = 6) or by 4 mm femoral arterial puncture with 45 s free bleeding period (CBG = 8, TMS = 8). After injury, dressings were applied, followed …

Evaluation And Management Of Peripheral Nerve Injury, William W. Campbell

Uniformed Services University of the Health Sciences

Common etiologies of acute traumatic peripheral nerve injury (TPNI) include penetrating injury, crush, stretch, and ischemia. Management of TPNI requires familiarity with the relevant anatomy, pathology, pathophysiology, and the surgical principles, approaches and concerns. Surgical repair of TPNI is done at varying time intervals after the injury, and there are a number of considerations in deciding whether and when to operate. In neurapraxia, the compound muscle and nerve action potentials on stimulating distal to the lesion are maintained indefinitely; stimulation above the lesion reveals partial or complete conduction block. The picture in axonotmesis and neurotmesis depends on the time since …
