While waiting to cross a street, a 30-year-old woman was suddenly struck by an oncoming vehicle, which crushed her legs against a parked automobile. She sustained a life-threatening traumatic injury and nearly exsanguinated at the scene. Nearby pedestrians assisted her, including a man who applied his belt to the woman’s left thigh to prevent complete exsanguination following the crush. She was emergently transported to an adult regional trauma center and admitted to the ICU.
The patient was given multiple transfusions of packed red blood cells, platelets, and frozen plasma in attempts to restore hemostasis. She underwent emergent surgery for a complete washout, debridement, and compartment fasciotomy on the right leg. The left leg required an above-knee amputation. Following surgery, full-thickness and split-thickness wounds were present on both extremities.
Before the accident, the woman had a history of hypertension controlled with a single antihypertensive. She was obese, with a BMI of 31.9. She had no surgical history. She denied excessive alcohol consumption, illicit drug use, or smoking. She was unaware of having any food or drug allergies.
The woman was married and had a 6-month-old baby. Until her accident, she was employed full-time as an investment accountant. She expressed contentment regarding her home, family, work, and busy lifestyle.
Once the patient’s condition was stabilized and hemostasis achieved in the trauma ICU, the bilateral lower-extremity wounds were managed by application of foam dressings via negative-pressure therapy. The dressings were changed on the patient’s lower-extremity wounds three times per week for about three weeks. When the wounds’ depth decreased and granulation was achieved, split-thickness skin grafts (STSGs) harvested from the right anterior thigh were applied to the open wounds (see Figure 1) in the operating room.
Following application of the STSGs and hemostasis of the patient’s donor site, silver silicone foam dressings were applied directly over the right lower-extremity graft and the donor site in the operating room. The dressings remained in place for four days (see Figure 2). A nonadherent, petrolatum-based contact layer was then applied to the left lower-extremity amputation graft site, followed by a negative-pressure foam dressing.
The negative-pressure pump was programmed for 75 mm Hg continuous therapy for four days. The silver silicone foam and negative-pressure foam dressings were removed from the respective graft sites on the fourth postpostoperative day. The grafts were viable and intact (see Figures 3 and 4). The silver silicone foam was reapplied to the lower-extremity STSGs and donor site and changed every four days.
When a few pinpoint dehisced areas were noted on the grafts, a silver-coated absorbent antimicrobial dressing was applied. A nonadherent, petrolatum-based contact layer, followed by wide-mesh stretch gauze, was secured as an exterior dressing over the graft sites. Both lower-extremity dressings were layered with elastic wraps to prevent edema. The dressings were changed daily for two weeks.
On postoperative Day 4, the silver silicone foam was removed from the donor site. A nonadherent contact layer of bismuth tribromophenate petrolatum, followed by the silver silicone foam, was selected for placement over the donor site. Gauze and an elastic wrap were secured as an exterior dressing and removed three days later.
The donor site dressing was reduced to a layer of bismuth tribromophenate petrolatum and left open to air. As the edges of the nonadherent contact layer dried, they were trimmed with scissors (see Figure 5). A moisturizing cocoa butter–based lotion was applied daily to the exposed areas of the donor site.
During the patient’s third postoperative week at the trauma center, as she underwent a continuum of aggressive rehabilitation and wound care, the donor and STSG sites were pronounced healed (see Figures 6, 7, and 8). The donor site was left open to air, with daily use of cocoa butter lotion. Maintenance care of the graft sites included daily application of cocoa butter lotion, stretch gauze, and elastic wraps. The patient was discharged from the rehabilitation unit to home, where she awaited a prosthetic fitting.
Throughout the patient’s hospitalization and rehabilitation, surgical, medical, pain, and nutrition management were monitored on a continuum, as were laboratory values. Her vital signs remained within reasonable limits. The patient remained infection free and experienced neither medical nor surgical complications during the course of her hospital stay.
DISCUSSION
Traumatic injuries often result in bodily deformities, amputations, and death. They represent the leading cause of death among people in the US younger than 45.1,2
Compartment syndrome develops when increased pressure within a bodily cavity minimizes capillary perfusion, resulting in decreased tissue viability.3 Edema and hemorrhage are also precipitating factors for this condition.3 When it goes unrelieved, compromised circulation can lead to muscle devitalization. Amputation of the affected appendage may be necessary unless circulation is restored.
