A gentle forward push must be maintained during the excision generic 50 mg viagra super active with mastercard erectile dysfunction treatment exercise, but the real action of the dermatome is determined by the delicate back-and-forth action of the body of the dermatome cheap viagra super active 100mg overnight delivery erectile dysfunction statistics age. The complete width of the dermatome must be used in the action, while maintaining the excision in its precise location. Pressure must be avoided, and all muscles in the hand and forearm must be relaxed to allow precise control of the instrument (Fig. An assistant should hold the burned tissue being excised, allowing the surgeon total control over the progression of the excision. Pressure must not be applied while holding the burned tissue because this deepens the plane of excision. It must only be considered when dealing with full-thickness burns in which it is imperative to excise the complete thickness of the skin to graft on subcutaneous tissue. They are helpful in the management of large minor burns, but the excised surface must be inspected to identify nonviable tissue. Small areas of nonvital tissue must be then excised with the handheld dermatome to avoid excision of surrounding vital tissue. When gross destruction of soft tissues is present, en bloc resection of the damaged area is recommended. The resection does not differ from any other fascial resection; and the reader is referred to Chapter 6. When this type of resection is performed, flap coverage may be necessary in selected anatomical locations. Hemostasis Extensive bleeding may occur during burn surgery that challenges the patient’s hemodynamic stability during and after surgery and graft take. The recommended hemostatic measures during burn surgery include the following: Tourniquets Topical epinephrine solution Subcutaneous infiltration of epinephrine solution A B C FIGURE10 A. Hand dermatomes are commonly used for excision of burned tissue, although large flat surfaces may benefit from excision with powered dermatomes. The Wat- son knife is used to excise large areas; the Goulian dermatome is used in small areas and face, hands, and feet. A gentle forward push must be maintained, but the back-and- forth movement, which should accommodate the complete length of the instrument, determines the real action. If the burns extend to the area where the tourniquet is to be applied, the area is excised first and covered with epinephrine-soaked Telfa dressings. After completion of the burn excision, the area is dressed with epinephrine-soaked Telfa dressings and the tourniquet is deflated. If the burn surgeon lacks the necessary experience with excision under tourniquet control, tourniquets may be briefly deflated to assess accurate excision of all devitalized tissue and inflated again. When the surgeon has enough experience, the operations may proceed without tourniquet deflation (Fig. The application of epinephrine-soaked (1:10,000) Telfa dressings has proved very effective in achieving complete hemostasis of excised burn wounds. This allows removal of the dressing without starting new bleeding points. The surgeon must be confi- dent that all nonvital tissue has been removed before the epinephrine is applied to the wound because the wound acquires a cadaveric appearance after the applica- tion and it is not longer possible to assess the extent of the excision. Epinephrine- soaked laparotomy pads are placed on top of the Telfa dressings and then wrapped with elastic bandages. All blood clots are wiped with the Telfa dressings and evident arterial bleeding points are controlled with diathermy.

Lymphocyte counts and such as the skin and mucous membranes that can be B-cell function are decreased after intense exercise but impaired by temperature, wind, sun, humidity, and not after moderate exercise (Pedersen and Toft, 2000). Cross-country skiers and cyclists have low base- and mucosal immunoglobulin-A (IgA) activity affect line salivary IgA levels that drop after racing (Eichner, airborne respiratory pathogens (Nieman, 1999). Longitudinal studies of salivary IgA in elite pended until they reach the bronchi and bronchioles swimmers, however, have reported increases where the mucous barrier, rich in IgA, impedes fur- (Bruunsgaard et al, 1997), decreases (Gleeson et al, ther invasion (Shephard and Shek, 1999). Depressed IgA levels have been noted in cross- (Bruunsgaard et al, 1997), male triathletes showed country skiers, cyclists, and swimmers (Eichner, diminished skin test measures of cellular immunity 48 h 1993; Nieman, 1999; Brenner, 1984). There is thus a decreased clearance of infectious peting triathletes and recreational athletes. NK counts (Woods, 1999) and natural killer cell organisms are theoretically more likely to invade the activity (NKCA) (Nieman, 1999) increase immedi- host and cause an infection (Nieman, 1999; Shephard ately after high intensity exercise lasting less than and Shek, 1999; Brenner, 1984; Pedersen et al, 1 h, but fall soon after to below preexercise levels 1996). NKCA is elevated chronically in elite versus untrained athletes (Nieman, 2000), but not with moderate exercise (Woods et al, 1999). Chronic exercise attenuates this Marathon runners have a higher incidence of self- response, but macrophage function is greater than reported upper respiratory tract infections (URI’s) after in nonathletes (Woods et al, 1999).

A similar study of healthy, elderly people noted an infections, however. A follow-up study (Gleeson et al, inverse relationship between the amount of energy 2000) showed no correlation between salivary IgA expended in daily moderate activities and URI levels and infection risk. Runners in short races (5K, 10K, half-marathon) decreased salivary IgA an average of 27. There was a negative correlation found running 16–26 mi a week increased the risk between salivary IgA levels and number of days of ill- of having ≥1 URI compared to running <9 mi a ness and flu symptoms, but not days of cold symptoms. Running 9–16 mi or >26 mi a week con- Studies of immune marker changes with exercise have ferred intermediate risk. Moderate exercise lowers infection risk to below that of being sedentary, while strenuous In premenopausal women, no exercise or a 15-week exercise imposes the highest risk of all (Nieman, walking program made no difference in NK cell 2002).

NKCA and lymphocyte proliferative response were significantly higher in the rowers.

Barret Broomfield Hospital, Chelmsford, Essex, United Kingdom INTRODUCTION Trauma can be defined as bodily injury severe enough to pose a threat to life, limbs, and tissues and organs, which requires the immediate intervention of spe- cialized teams to provide adequate outcomes. Burn injury, unlike other traumas, can be quantified as to the exact percentage of body injured, and can be viewed as a paradigm of injury from which many lessons can be learned about critical illness involving multiple organ systems. Proper initial management is critical for the survival and good outcome of the victim of minor and major thermal trauma. However, even though burn injuries are frequent in our society, many surgeons feel uncomfortable in managing patients with major thermal trauma. Advances in trauma and burn management over the past three decades have resulted in improved survival and reduced mortality from major burns. Twenty-five years ago, the mortality rate of a 50% body surface area (BSA) burn in a young adult was about 50%, despite treatment. Improved results are due to advancements in resuscitation, surgical techniques, infection control, and nutritional/metabolic support. The function of the skin is complex: it warms, it senses, and it protects. A burn injury implies damage or destruction of skin and/or its contents by thermal, chemical, electrical, or radiation energies or combinations thereof. Thermal injuries are by far the most common and frequently present with concomitant inhalation injuries. When the skin is seriously damaged, this external barrier is violated and the internal milieu is altered.
