The definitive results should be evaluated once the phase of secondary scarring has been completed cheap skelaxin 400mg amex uterus spasms 38 weeks, between 6 and 12 months after the burn in cases in which hypertrophic scarring does not occur buy skelaxin 400mg otc spasms below rib cage. The recovery method of choice for deep burns of the hands following an early escharectomy includes cutaneous grafts taken from the same patient. Limitations in the amount of available cutaneous graft donor areas should not be, in our opinion, a restriction against using them on the hand. The surgical technique for collecting and placing cutaneous grafts has been described in detail in other chapters. However, a thicker graft will cause less secondary scar retraction, which is especially relevant when treat- ing burned hands on children. Full-thickness cutaneous grafts may be indi- cated for hand burns in areas that are sensitive to secondary contraction, especially with pediatric patients. There does not appear to be any significant difference in the functional results of treatment by cutaneous coverage of burned hands based on the thickness of the grafts used on adults. Graft expansion methods are generally not indicated for burned hand coverage, since the area to be covered is not extensive. When placing these cutaneous grafts, we have found that adhesive sutures for coverage of the digits of the burned hand are especially useful (Fig. It is very important to splint the hand and digits in the intrinsic plus 266 Go´mez-Cıa´ and Ortega-Martınez´ position, with the thumb in flexion, opposition, and abduction. Some authors suggest placing the hand in fist position when placing the graft because they believe that the amount of graft material needed can be better estimated [15,16]. When the digital extensors, ligamentous apparatus, or joints have been damaged, we use internal splinting of the affected segment using K-wires until the wound has healed. We examine laminar grafts of the hands 24 hours after surgery to eliminate seromas and hematomas, which may accumulate beneath the graft, and to apply a new nonadherent bandage. Grafted hands should be elevated with respect to the position of the patient’s body by placing them on a pillow or by elastic traction above the patient, and splinted in the position described previously. Occasionally, skeletal traction may be useful alone or in association with devices such as the ukelele, horseshoe, or others. Once the graft is secure, the patient should then begin active and passive mobilization of the joints of the digits, hand, and wrist. A splint is used to maintain the correct position of the hand while the patient is resting. If deep structures are exposed, such as tendon lacking a peritenon, bone lacking periosteum, joints, or nerves, after burn debridement, cutaneous grafts are not indicated. In such cases, it is necessary to use local flaps, distal flaps, or occasionally free flaps. In addition to the classic flaps, based on a proximal, random, or axial vascular pedicle, proximal cutaneous regions based on distal vascular pedi- cles using inverse flow are also useful. Cutaneous losses in the pulp of the long digits occurs frequently with low- voltage electrical burns in children. When bone is not exposed and the injury is less than 1 cm2, it is justifiable, in our opinion, to take a conservative approach and allow the wound to close by spontaneous scarring. If the injury is greater than 1 cm2, it may be covered with full-thickness skin graft. If bone is exposed, and if the injury is small, we identify two distinct approaches: If the injury is perpendicular or bevelled dorsally, we can use the V-Y advancement palmar flap [18,19], which is based on the ascending arteries that branch off of the distal central artery of the pulp. If the injury is bevelled obliquely on the palmar surface, we do not use tissue from the part distal to the pulp and proximal to the injury. We use tissue lateral to the pulp by means of the V-Y advancement lateral flap. The advancement–rotation quadrangular flap may also be used to close such small injuries. The difficulty with this technique is that the area that is most damaged, which is the part that must cover the end distal to the pulp, is the least sensitive part of the flap. These three flaps have the advantage of being simple, but they provide less sensation than the neurovascular island flap. This flap involves V-Y The Hand 267 displacement of the side of the digit that includes the complete collateral pedicle from the side of the injury. For this reason, most authors consider this the method of choice for such injuries.

Barret Broomfield Hospital, Chelmsford, Essex, United Kingdom The treatment of major burn injuries with immediate (within 24 h from the injury) total burn wound excision (all full-thickness and deep dermal injuries are excised and homografted) has been described in chapter 9. Two main approaches have proven effective for the treatment of massive burn wounds: Immediate burn wound excision Serial or sequential early burn wound excision They differ significantly in terms of timing of surgery (first 24 h vs. They represent an alternative for each other, and there is still great debate regarding the timing and extent of excision, especially in patients whose survival is questionable. The general philosophy of the major burn excision reviewed in Chapter 9 is entirely valid for both approaches. However, intraoperative and postoperative care issues differ as to the extent of the surface to be excised and the number of times the patients has to return to for further skin autografting procedures. A third therapeutic approach used in some burn centers throughout Europe is the treatment of massive burn injuries with daily or twice-daily application of cerium nitrate–silver sulfadiazine (Flammacerium) and delayed excision and autografting. Some reports suggest that patients present with improved and re- covered inmunological function and good protection against invasive burn wound 249 250 Barret infection. All three therapeutic approaches are summarized and compared in the following sections. IMMEDIATE TOTAL BURN WOUND EXCISION In this therapeutic approach, all deep dermal and full-thickness burns are excised after admission, ideally within 24 h of injury. Resuscitation is started and carried on during surgery, and urine output and other hemodynamic parameters govern it. Operative losses are replaced with reconstituted whole blood (one unit of fresh frozen plasma one unit of packed red cells) calculated to replace a blood loss of 0. Blood gas analysis and measurement of blood count and electrolytes are repeated every 30 min during surgery to determine the adequacy of fluid resuscitation and operative blood loss replacement. Patients receive peri- operative antibiotics to prevent postoperative sepsis due to bacterial translocation from the gut. Donor sites are harvested first, unless paucity of donor sites necessitates the use of culture keratinocyte techniques, in which case a skin biopsy is obtained to perform such techniques. If planned wound closure includes the use of Integra, donor sites are not harvested at this time. The patient is placed in the supine position and any deep dermal and full- thickness burns on the anterior torso and abdomen are excised. Active arterial and large venous bleeder points are controlled with diathermy and bipolar cautery. A second opera- tive table is placed parallel to the main operative table and the patient is turned prone. The back is then excised and hemostasis is obtained in the standard fashion. Wound clo- sure may proceed by three different but complementary approaches: 1. Split-thickness autografts meshed 4:1 with an overlay of nonmeshed allografts (sandwich technique) 3. Split thickness autografts meshed 2:1 The meshing pattern used for wound closure depends on burn surface area and donor site availability. Following wound closure, the grafts or skin substitutes are secured with a bolster (should include the whole back), or Biobrane. This order is advised to prevent any blood loss pouring onto the dressing applied on the back.

A number of patient-, physician-, and system-related issues converge to make treating chronic pain a complex matter. Patient-related issues include an inability to define a clear anatomic cause for patients’ pain, comorbid psychiatric conditions, and past and current substance abuse. Physicians lack training on the appropriate evaluation and treatment of chronic nonmalignant pain, fear creating addicts, and often face intense pharmaceutical industry pressure to pre- scribe medications. A paucity of practical clinical practice guidelines, controversy over the effectiveness of opioids on chronic nonmalignant pain, and concern about potential legal and regulatory ramifications add to the complexity of caring for these patients. Possible multi- faceted solutions exist to minimize provider discomfort and improve their ability to treat patients appropriately. Examples include comprehensive, practical multidimensional guide- lines on the evaluation and treatment of chronic nonmalignant pain, Web-based teleconfer- enced consultations with subspecialists, reduced pharmaceutical pressure, enhanced continuing medical education and pregraduate training, multispecialty coordinated care of patients with adequate reimbursement for such care, and physician access to state-based systems to track opioid prescriptions. Karger AG, Basel Introduction Office-based physicians encounter pain, whether acute or chronic, on a daily basis. Most primary care physicians (PCPs) do not have difficulty managing acute pain – evaluating, locating, and treating causes of acute pain is what their medical training best prepares them to do. The epidemiology of chronic nonmalignant pain in primary care, however, dictates that physicians also need to know how to manage this common problem. The World Health Organization, in a large, cross-national survey, estimated that the prevalence of persistent pain in primary care settings ranges from 5. Other researchers in smaller studies of patients and physicians in primary care offices have documented prevalence rates of 11–45% [3–5]. Chronic pain is the lead- ing cause of disability in the United States, with arthritis alone resulting in 750,000 hospitalizations and 36 million outpatient visits annually. The Centers for Disease Control estimates that the total cost of arthritis, including lost productivity, exceeds USD 82 million per year. Despite its frequency and tremendous economic and societal burden, research shows that chronic pain often goes undertreated. According to the Michigan Chronic Pain Study, in 1997, 20% of the adults in Michigan suffered from chronic pain conditions and 70% of the survey responders reported having persistent pain despite treatment. An American Pain Society (APS)- sponsored survey of chronic, nonmalignant pain sufferers with moderate to severe pain found that 41% of the 805 respondents reported not having their pain under control despite medications and adjuvant therapies. In managing chronic nonmalignant pain, most PCPs feel comfortable prescribing nonopioid therapies, such as all the classes of nonsteroidal anti- inflammatory drugs, Tylenol, and muscle relaxants, and nonpharmacologic treatments such as physical therapy. However, all PCPs have encountered patients for whom these medications and therapies are not enough and who require stronger medications in the form of opioids prescription. Multiple patient, physician, and system-related issues converge to make PCPs often uncomfortable about prescribing opioids for chronic nonmalignant pain (fig. Patient-Related Issues Patients with chronic nonmalignant pain often have no identifiable anatomic lesion that PCPs can point to as a clear cause of pain and that, in a doctor’s mind, better justifies the use of long-term strong opioid medications. Without objective evidence of pathology, there is less to counter the multi- ple forces that weigh in on the side of not prescribing opioids.

Research has shown that chronic pain patients tend to have a higher preva- lence of comorbid psychiatric disorders, such as depression and borderline personality disorders, and that the presence of these conditions is associ- ated with poorer pain control. Within the past 20 years, PCPs have improved significantly in their treatments of depression, but when depres- sion is combined with chronic pain and personality disorders, these patients often become complicated and frustrating.
