Tears in the pharynx and trachea may result in mild to massiveĪccumulation of air beneath the skin (subcutaneous emphysema).Īir distention displaces the skin, creating a dead space pocket of air. This accumulationĬan further expand the dead space by stretching or displacing Significant accumulation of blood, serum, or pus. Depending on the age and condition of the wound, tissue fluid,īlood, or pus may collect in the traumatized area and gravitate in a

Herniation of abdominal contents also may be noted. Wounds are noted as gaps or depressions with deep digital palpation. Patient (provided the area is uninjured). Musculofascial tissue suspected areas of tissue disruption can beĬompared with the corresponding area on the opposite side of the Palpation over areas of intact skin may reveal irregularities of the Present, lifting the skin creates a vacuum effect, which sucks air into When grasped, the skin readily liftsĪway from the underlying musculofascial layer. Disrupted tissue planes may include separation of the skin from the Presentation as well as pain anticipated for the surgical procedure Patients should be assessed and treated for pain at the time of All trauma patients require a complete physical examination, Treatment should be instituted in critically injured patients. “ABCs” (airway, breathing, and circulation). Vital signs should be immediately assessed, including the basic High-velocity projectile wounds can cause significant tissueĭisruption and significant dead space formation as a result ofĬavitation and tissue trauma secondary to fragmentation of bone įrangible bullets also intensify local tissue trauma. Wound management, tissue trauma, circulatory compromise,Ĭontamination, and formation of dead space predispose the Laceration of the skin and underlying tissue. Bite wounds often result in the crushing, stretching, tearing, and Variable degrees of soft-tissue disruption and dead space Orthopedic trauma and subsequent fracture repair can result in Bothĭirect and indirect trauma can cause soft tissue to stretch, tear, or

Vehicular trauma is the most common form of blunt trauma. Loose or elastic fascial planes are potential areas for fluidĪccumulation, especially in the face of regional trauma. Combined with surgical traumaĪnd regional movement, seromas formation may occur. Wide surgical dissection results in disruption of normal tissue Mass (e.g., tumor, granuloma, organized hematoma) is removed The volume of a pocket or defect created when a space-occupying These options include no treatment, external bandageĬompression, suture closure, use of a drainage system, andĪspiration each can be used alone or in combination to control There are several techniques used to manage dead space,ĭepending on the size, location, and cause of the tissue pocket. Important to both the and management of infection. As a result, appropriate dead space management is Moreover, fluid accumulation mayĬontribute to infection, especially in the presence ofĬontaminants. Dead space creates a pocket or cavity in which tissue fluid orīlood can accumulate (e.g., seromas, hematomas) excessive fluidĪccumulation separates tissue planes, and its persistence can delay Wounds, vehicular trauma, high-velocity projectile wounds). Tissue separation or disruption secondary to trauma (e.g., bite Removal of a space-occupying mass or evacuation of fluid, tissueĭissection resulting in disruption of tissue or facial planes, and The term is commonly used to describe spaces resulting from the Dead space, by definition, is a space left in theīody as a result of a surgical procedure.
