The infiltration of deep partial- thickness burns may lead to excision of vital tissue in inexperienced hands generic extra super cialis 100mg mastercard. Dermis becomes congested and acquires a cadaveric appearance after infiltration. Vast experience is needed with this technique to avoid extending the excision to deeper planes of living tissue. Other techniques that have been explored to control blood loss during burn surgery include use of fibrin sealant and bovine thrombin. These agents are very A B C FIGURE 12 The use of sterile tourniquets provides excellent blood loss control. The tourniquet is inflated before excision and (B) excision is performed. As an alternative, the tourniquet can be deflated to assess the depth of excision and then reinflated (C). When epinephrine-soaked dressings have been applied to the wound, it is not longer possible to assess the extent of the excision because the wound acquires a cadaveric appearance (D). Some studies have shown a significant decrease in blood loss during burn surgery with their use, although combination with topical or subcutaneous epinephrine renders the best hemostatic effect. Fixation of Skin Grafts and Splinting Many techniques for skin graft fixation are documented in the medical literature. The methods extends from paper tape to fibrin glue, but the most frequently used are metallic staples, resolvable sutures, and bolsters or tie-overs. Skin grafts must not extend over normal skin because that will lead to desiccation and infection. Graft seams need to be overlapped a few millimeters to provide good coaptation and avoid open wounds during the rehabilitation phase. One edge is fixed first, and the graft is then stretched until full tension has been achieved. If the wound is small enough to be covered with one single skin autograft, the opposite edge is fixed before the rest of the graft is sutured. When more than one graft is needed, the next graft is placed beside the previous graft and they are fixed together to provide enough tension to the first skin autograft.

The use of immunohistochemisty discount 100mg extra super cialis with visa, infrared fluorescence, and laser Doppler studies all show promise in vitro, but a trained surgeon has been shown to be at least as good. The cause of the burn, inspection and palpation of the wound, and sensory nerve function are all important clues. Finally, excision of very deep burns over joints, tendons, and bones may leave a wound that may not accept a skin graft. Some truisms regarding burns and burn care include the following: Burns in patients at the extremes of age are not shallow. Except for contact burns, most burns of the palms and soles heal within 3 weeks. Patients whose clothing or bedding has been on fire rarely escape without some full-thickness burns. All electrical burns are full-thickness and should be assumed to be fourth- degree. Flash burns are rarely full-thickness, except in areas of very thin skin. Burns from hot soups and sauces are deeper than those from hot water alone. Principles of Burn Surgery 137 Burns resulting from direct contact with a tar pot are usually very deep dermal or full-thickness burns, while those from tar that has been trans- ferred into a bucket or spread on a surface are usually shallow. Small burns that will eventually heal present little threat to life if allowed to heal over several weeks. Inadequate excision with skin grafting on a poor bed leads to skin graft loss, adds the size of the donor site to the total area of open wounds, and may necessitate another operation. Non-life-threatening burns in patients with associated medical problems or injuries should not be excised until the associated problems are under control and the operation can be done with low morbidity and essentially no mortality. Patients with burns of the hands and feet will be able to return to work sooner if their burns are excised and skin grafted shortly after hospital admission. Large, superficial burns with scattered small deeper components are best treated nonoperatively until the shallow areas have healed.
