Ade- quate analgesia is frequently not achieved for the burn-injured patient discount 300 mg tinidazole with mastercard antibiotics for acne resistance. Back- ground pain results from the burn and is accentuated by surgical burn debridement at the recipient site and autograft harvesting generic tinidazole 500mg line virus 1999 movie. Procedural interventions that are painful for the patient include dressing changes, application of topical antimicro- bial agents, and physiotherapy. Trauma and metabolic requirements can be effec- tively minimized by liberal usage of opioid analgesics such as morphine and fentanyl analogues, sedative agents, and anxiolytics [42a]. Psychological support of the burned patient is crucial in addition to pharmacotherapy. PHYSICAL EXERCISE PROGRAM Accretion of lean muscle mass requires, in addition to a high-carbohydrate diet, a resistance exercise program. Formal supervision of this program by a physiotherapist or occupational therapist is required to direct attention to specific areas requiring greater attention, to prevent and minimize the effects of burn scar contracture and to ensure compliance. A supervised, coordinated 12 week inpa- tient program of resistance exercises has shown 50% greater accretion of lean muscle in patients who completed this program than in patients who followed standard exercise regimens as outpatients (Fig. Exercise programs in burned children undergoing rehabilitation appear to be safe, since children effec- tively dissipate the heat generated during exercise. Children not only show significantly improved peak torque and stamina after undertaking an exercise program but also have notably improved pulmonary function. COMPLICATIONS Localized infection of the burn wound very frequently results in generalized septicemia. Sepsis can markedly increase the metabolic demands in the burned patient. Prevention of infection and sepsis are critical therapeutic manoeuvers to decrease the hypermetabolic response. Burn infection scores may be extremely useful to define infection, which is difficult to do clinically, in a hypermetabolic Metabolic Response 299 FIGURE 3 Muscle strength after exercise. Scores defined by the Society of Critical Care Medicine or Ameri- can Academy of Chest Physicians are useful (Fig. Infection can increase the metabolic rate (as determined by stable isotope studies) in burn-injured patients by 40% relative to patients with like-sized burns that do not become septic. This large increase in metabolic rate persists throughout the patient’s hospital stay and well into the rehabilitation period. Local and systemic infection may be prevented by the early coverage of the burn wound by either split-thickness auto- graft or synthetic materials. The other major therapeutic manoeuver shown to have a marked effect on metabolic rate is early excision and closure of the burn wound. Early burn wound excision and coverage with widely meshed autograft covered with cadaver skin, combined with cadaver skin used to cover all other non-grafted remaining areas, results in decreased operative blood loss, decreased length of stay, fewer septic complications, and decreased mortality in children and young burned adults compared to patients treated with serial debridement [13,48–50]. A significant reduction in catabolism and amelioration of the hypermetabolic response is also achieved. Biobrane is a synthetic wound dressing that has been used successfully to cover superficial second-degree burns until spontaneous healing occurs. In burns greater than 40% TBSA, this has shown superior results to conventional dress- ings, expressed as a significant reduction in pain, time to healing, inpatient stay, and metabolic response to the burn. Deep dermal burns (deep second-degree or deep partial-thickness) greater than 40% TBSA achieve superior healing when early coverage is achieved using cadaveric allograft compared to application of topical antimicrobial agents. Hospital stay is reduced and significantly decreased pain levels and rates of infection serve to temper the hypermetabolic response markedly. Early coverage of the debrided burn wound is the key to reduction of the hypermetabolic response exhibited by the burn-injured patient. Early debridement and coverage with either cadaveric skin or skin substitutes such as Integra or Dermagraft within 48 h of injury have shown results superior to delayed burn wound closure at 7 days [54,55]. Biological dressings and skin substitutes require subsequent autografting when the skin substitute has achieved sufficient biointe- gration with the wound bed.
