Growth then remains constant for several years until the onset of the pubertal growth spurt, which occurs some 2 years earlier, on average, in girls than in boys. Height is dependent on the rate of growth and is com- pared against standardized values. These standardized values are based on the statistical analysis of very large populations. Unfortunately, most of the corresponding tables are already several years old and, given the phe- nomenon of acceleration, no longer accurately reflect the current situation, since children now grow taller, on aver- age, than they did 20 years ago ( Chapter 1.

Donor sites are then dressed with epinephrine-soaked Telfa dressings for 10 min cheap 50 mg anafranil overnight delivery. The Small Burn 203 The scalp provides the surgeon with the best quality of skin for burn surgery buy anafranil 75 mg low price. The harvesting is practically painless and the donor site remains concealed pro- vided the hairline is not crossed discount anafranil 25 mg on-line. The scalp should be considered the first choice in infants and small children and when excision and grafting of face burns are considered. The following are some of the principles for successful harvesting of scalp donor sites: 1. Infiltrate the area to be harvested with 1:200,000 epinephrine solution. Provide enough tension to facilitate the harvest by achieving a flat surface. The head should be fixated by an assistant to allow control and good exposure 6. A scrubbed anesthetist should hold the endotracheal tube and protect the airway (Fig. Apply epinephrine-soaked (1:10,000) Telfa dressings when harvesting is completed. When the scalp is not an option as a donor site (either due to concomitant scalp burns or lack of parent or patient’s consent), the buttocks are the second choice in small children who are still in diapers. For older children, the thigh or back provides the surgeon with plenty of skin grafts. It is more painful to harvest than the scalp, but it is easy to dress and care for, and it heals properly in few days. Infiltration of subcutaneous epinephrine solutions should be considered to obtain good hemostasis, although it is not necessary to use tumescent technique to provide good tension. An assistant should hold the limb in good position and the muscles should be positioned in tension. The thigh is then serially harvested until enough quantity of skin grafts has been obtained. Epinephrine-soaked Telfa dressings are then applied to the donor site and the thigh is dressed after 10 min. Medium-sized burn injuries present with extensive graft requirements be- yond those available from scalp or thigh donor sites. Even though some medium- sized burns can be grafted by using both thighs, the back is usually the best donor site for these injuries. Large amounts of skin grafts with excellent quality are readily available from this area. However, many surgeons dislike using skin from the back because the patient has to be positioned prone. The use of a second operating table to roll the patient and on which to harvest the back can solve this problem. A B FIGURE 8 The scalp is an excellent donor site for split-thickness skin autograft. The hairline should be drawn before shavingto avoid inadvertent harvest of skin in the upper neck posterior neck and on the forehead. A second operating table is placed parallel to the main operating table and sterile drapes are prepared. The patient is then rolled onto the second operating table and the main operating table is moved aside. The back is prepped in the standard fashion and the area infiltrated with 1:200,000 epinephrine solution. It is impera- tive to infiltrate the back, because good tissue tension is needed to provide good- quality skin grafts. Moreover, an even surface is needed, since all bony structures (especially ribs) preclude any good grafting technique unless Pipkin’s technique is used. Graft requirements are then drawn onto the back surface according to burn wound measurements and long strips of medium-thickness skin grafts are harvested. It is necessary to change the blade of the dermatome very often: it becomes dull very quickly due to the thickness of the dermis.

This is an example of how the operative plan may change based on the area of the burn best anafranil 75mg. Once the techniques for excision and closure of the wound are chosen buy 75mg anafranil with mastercard, care must be taken to provide a technically sound result buy anafranil 25 mg lowest price. Although in small burns local flaps can be used for wound closure, most significant burn wounds will require closure with skin grafts. These are applied to wound beds where the cells of the graft are kept alive by nutrients in the serum produced by the wound bed until vascularization takes place (1–4 days after application). For this process to take place and for the skin graft to take, four things are required: A viable wound bed No accumulation of fluid between the graft and the wound bed 224 Wolf No shear stresses on the wound Avoidance of massive micro-organism proliferation Performance of the selected technique must be reliable to ensure adequate out- come. Then meticulous attention should be paid to placing the grafts and adhering them to the wound bed. Consideration should be given to the lines inherent in placing grafts either from the meshing or the grafts themselves in order to minimize cosmetic scarring. Selection and application of the dressing are equally important: the dressing should apply pressure to the wound to minimize dead space under the graft, minimize shear stress, and provide antimicrobial properties. This portion of the operation is often overlooked, and if performed inadequately will lead to poor results. Wound Healing and Scarring The skin is made up of two distinct layers: the epidermis and dermis; function of the skin depends on the presence of both. The epidermis, made primarily of keratinocytes, provides a continuous moisture and antimicrobial barrier. The underlying dermis is responsible for most of the other functions of the skin, including shear strength, pliability, contour, eccrine function, hair production, sensation, and so on. When the skin is lost from injury, the wound is closed by contraction, keratinocyte migration, and/or skin grafts. Most of the modern techniques of wound closure involve replacement of the epidermis to re-establish barrier continuity, which is generally successful. What is absent after closure is most of the dermal layer that is responsible for all the other functions. In its stead a neodermis of disorganized fibroblasts, macrophages, and collagen forms under the epidermal layer. This layer provides for continued wound contraction, hyper- trophic collagen deposition, and is a nonpliable surface, which we typically asso- ciate with scarring. It was found long ago that wound closure with full-thickness skin grafts containing a complete epidermis and dermis provides for the best outcomes in terms of wound contraction, appearance, and pliability. As a general principle, therefore, a graft with increasing levels of dermis should provide the best func- tional and cosmetic outcomes. Split-thickness donor sites can be taken at many depths, the deeper of which contain more dermis. When these are used as auto- grafts, these sites will have decreased scarring. The limitation to this is that deep donor sites leave significantly increased scarring at the donor site. This should be kept in mind during operative planning and the use of donor sites. OPERATIVE INDICATIONS AND PLANNING Once the initial urgent measures for burn resuscitation have been undertaken, a plan of action for further management of the wound is necessary. This manage- The Major Burn 225 ment plan can include conservative and operative measures depending on the patient’s age and condition, burn depth, burn size, and burn wound location. This assessment is very important: it will dictate the proper treatment, including the need for operative treatment and the planning thereof. Burn depth is most accurately judged by the appearance of the wound to experienced practitioners. However, new technologies such as the heatable laser Doppler flowmeter with multiple sensors hold promise for quantitatively determining burn depth.

Examination of abduction From a position of 90° flexion, the hips are simultane- ously abducted and externally rotated. While the hips of a healthy neonate can almost always be abducted down to the examination table, abduction is inhibited in disloca- tion or subluxation of the hip in the first 3 months of life. Examination of the range of motion Neonates usually show a flexion contracture of around 30–40°. This is a physiological finding, since both hips are flexed more than 90° within the uterus. Since it is not possible therefore to examine rotation in the extended position, rotation is examined in the flexed position in the usual way. AP x-ray of the hips of an 18-month old infant with a high normally possible if the hip is flexed by more than 90° hip dislocation on the left side because of the tensing of the hamstrings. If the hip is dislocated however, the knee can be extended in this position. For further details on the examination of the hip in children and adolescents see also chapter 3. Radiographic diagnosis Radiographic diagnosis in infancy is almost completely irrelevant nowadays since it has been superseded by ultra- sound, an examination that not only involves no radiation exposure but one that is also more informative. Since the femoral head center starts to ossify after a year or so, the diagnosis must then be made radiologically. Other x-ray views do not produce reproducible results since large sections of the skeleton are still cartilaginous at this stage and thus not radiopaque. The AP view in the infant should always be an x-ray of both hips so that the pelvic position and the horizontal situation can be evaluated.
