摘要:
Prompt transfer of the child with acute burns can be difficult from distant or inaccessible locations, and it is believed that the outcomes of children with serious burns whose transfer to a specialized burn care facility is delayed may be compromised. A 4-year experience with 16 consecutive children with serious burns (≥ 20% of the body surface area) whose transfer to a burn care facility was delayed for 5 or more days was reviewed to document the difficulties that can follow such delays. These 16 children had an average age of 8.6 ± 1.6 years and an average wound size of 57.6% ± 5.8% of the body surface area, and they arrived a mean of 16.3 ± 3.4 days after the injury (range, 5 to 44 days). These children had undergone an average of 1 operation, excluding escharotomies, at referring facilities. Only 4 (25%) of the children had no infectious focus at transfer, and at admission resistant bacteria were recovered from 9 (56%) of the children and fungal organisms were found in 10 (63%). Compared with a concurrently managed matched control group of patients admitted to the burn center within 24 hours of injury, the delayed-transfer group had statistically significantly more bacteremia, renal dysfunction, wound sepsis, and central venous catheter days. It was also more expensive to manage these children; the delayed-transfer group required statistically significantly longer to achieve 95% wound closure, and they had greater total lengths of hospital stay and more rehabilitation days. The early transfer of children with serious burns to a specialized burn center may truncate hospitalization and thereby reduce costs. (J Burn Care Rehabil 1999;20:347–50)

摘要:
Abdominal compartment syndrome (ACS) is a well-recognized perioperative complication that occurs in patients who undergo intra-abdominal operations and who require extensive fluid resuscitation. The classic presentation of this syndrome includes high peak airway pressures; oliguria, despite adequate filling pressures; and intra-abdominal pressures of more than 25 mm Hg. A decompressive laparotomy performed at the bedside can alleviate ACS. If left untreated, sustained intra-abdominal hypertension is often fatal. In the literature, ACS has been described in pediatric patients with burns but not in adult patients with burns. This article describes 3 adults who sustained burns of more than 70% of their body surface areas, who required more than 20 L of crystalloid resuscitation, and who developed ACS during their resuscitation after the burn injury. The mortality rate among these patients was 100%, which confirms the grave consequences of this syndrome. In our institution, intra-abdominal pressure is now routinely measured as part of the burn resuscitation process in an attempt to diagnose and treat this syndrome earlier and more efficaciously. It is recommended that the possibility of ACS be considered when diagnosing any patient with burns who develops high airway pressures, oliguria, or both. (J Burn Care Rehabil 1999;20:351–3)

摘要:
High serum concentrations of procalcitonin (PCT), the 116 amino acid precursor protein of the hormone calcitonin, have been found in patients with various bacterial infections, particularly in those with sepsis. Because recent reports have shown that serum PCT constitutes a useful parameter for the diagnosis of sepsis in patients with several clinical conditions, a temporal analysis of the PCT concentrations in the plasma of 19 patients with severe burns (median body surface area burned, 32%) was conducted retrospectively. Nine patients were classified as septic on the basis of standardized clinical and laboratory parameters. Compared with the nonseptic group, these patients showed higher plasma PCT throughout the study period (median concentrations of septic vs nonseptic patient groups: 0.4 vs 0.2 μg/L on postburn day 2; 1.0 vs 0.3 μg/L on postburn day 4; 5.5 vs 0.3 μg/L on postburn day 7; 10.8 vs 0.5 μg/L on postburn day 9; 4.2 vs 0.4 μg/L on postburn day 12; and 1.7 vs 0.5 μg/L on postburn day 14), with differences considered to be significant (P< .05) from day 7 on. In contrast, differences in the plasma C-reactive protein concentrations were less pronounced and never reached statistical significance. PCT concentrations exceeding 15 μg/L were only observed in the 3 patients who died of sepsis-induced multiple organ failure. In addition to absolute PCT, individual time courses were also of diagnostic value. PCT is a highly efficient laboratory parameter for the diagnosis of severe infectious complications after a burn injury. (J Burn Care Rehabil 1999;20:354–60)

摘要:
Patients who have sustained thermal injuries may require tracheostomies as a result of facial burns; these operations may also be required after prolonged intubation for smoke inhalation injury or respiratory failure. For a patient with a temporary tracheostomy, speech may be achieved by occluding the opening of the tracheostomy cannula with the tip of a finger, thereby directing airflow through the vocal cords and allowing phonation to be produced. However, some patients who also have hand burns may not be able to cover the opening of the tube because of the injuries to their fingers and the bulky dressings covering them. A simple tracheal occluder can be made out of a ping-pong ball and a syringe casing. The device presented in this article allows for the restoration of speech in the types of patients described above, and it promotes purposeful movement of their upper extremities.

摘要:
Bioelectric impedance analysis (BIA) is used to measure the body composition and total body water of normal subjects. The purpose of this study was to determine if the hydration of patients with burns could be assessed by BIA. Assessments of total body water as determined by BIA and the tritiated water method were prospectively compared. The 2 analyses were performed 48 hours after admission for 5 patients with acute burns to determine the correlation of the 2 methods. The patients had a mean age of 36.4 ± 14.7 years (range, 20–56 years), a mean burn size of 39.4% ± 15.9% of the body surface area (range, 23%-65%), and a mean full-thickness burn size of 27.7% of the body surface area. The total body water was measured on admission and again at 48 hours postburn. There is an excellent relationship between BIA and tritiated-water-method determinations of the total body water of patients with severe burns (r= 0.958). This correlation suggests that BIA provides an accurate measure of total body water, and so it is a reliable means of monitoring fluid resuscitation in patients with burns.

摘要:
Assessment of functional outcome can be used as a measure of the effectiveness of intervention during recovery from a burn injury. This pilot study identifies the factors that are likely to be most important for determining standardized functional outcome measures for children after a burn injury; it highlights the contribution of these factors to variations in children's postburn outcomes. A focus group of 8 parents and a self-report questionnaire administered to 12 children and 13 parents were the means of obtaining information for this exploratory study. Itching was found to be one of the primary impairments that contributed to reduced functional outcome during skin healing after a burn injury. The activities of children who had been burned that were most frequently affected by the injury (as reported by parents) were schoolwork and sports; these were closely followed by sleeping, playing with other children, and unliked activities. Least affected activities were enjoying the family, eating, seeing friends, watching television, and bathing or showering. Eighty-five percent of parents reported at least some level of interference with the listed daily activities. Burn injuries are likely to cause interference with several aspects of a patient's daily life. As a result, families require ongoing support and monitoring. Further research should longitudinally compare the performance of children who have been burned with other children and adolescents. (J Burn Care Rehabil 1999;20:367–73)

摘要:
An in vitro bioartificial skin construct (BSC) model was studied to see how inflammatory infiltration affects apoptosis in skin that has been thermally injured. The BSC was used as a target organ. Control BSCs without leukocytes (CON) were burned (BCON) by scalding with phosphate-buffered saline heated to 70°C for 6 seconds, and they were then cooled with room temperature phosphate-buffered saline for 15 seconds. Human alloimmunocytes were added to CON to create rejection cultures (REJ) and to BCON to create burned rejection culttures (BREJ). Slides were stained with hematoxylin and eosin and anti-Lewis antibody. In situ labeling of apoptosis was measured by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). Those sections that were immunostained for Lewis Y were analyzed for intensity stain index (ISI = [Σ P0× I0]/total tissue area in pixels). TUNEL was quantified with the following equation: no. of total apoptotic cells/total tissue area. Necrosis and blister formation in the epidermal layer were evident in BCON and BREJ. Pyknosis and nuclear fragmentation—indicators of apoptosis—were also present. Phagocytosis of keratinocytes by leukocytes was seen in REJ and BREJ. Immunostaining showed greater expression of Lewis Y antigen, as determined by ISI, in REJ as opposed to CON (58.2 ± 2.3 vs 36.4 ± 2.3, respectively,P< .001), but no significant difference was found between BCON and BREJ (55.0 ± 5.7 vs 60.5 ± 3.4, respectively) and REJ and BREJ (58.3 ± 2.3 vs 60.5 ± 3.4, respectively). TUNEL staining indicated the presence of apoptosis as follows: REJ versus CON (0.0015 ± 0.0002 vs 0.0003 ± 0.0001, respectively,P< .001); BREJ versus BCON (0.0031 ± 0.0006 vs 0.0018 ± 0.0004, respectively,P< .05); REJ versus BREJ (0.0015 ± 0.0002 vs 0.0031 ± 0.0006, respectively,P= .007). The presence of leukocytes and thermal injury induces apoptosis in BSC. The combination of these two variables results in increased apoptosis as determined by TUNEL. These findings suggest that a common pathway for skin injury may include inappropriate regulation of apoptosis exacerbated by a mechanism that includes inflammatory cellular infiltration.

摘要:
Herpetic tracheobronchitis is a well-recognized clinical entity that most commonly occurs in immunocompromised patients, including patients with burns. Although the diagnosis of herpetic tracheobronchitis is usually not made until postmortem examination, the presence of the condition can be established when histologic specimens of a patient with upper airway obstruction are studied. In this article, a case is described in which a child developed herpetic tracheitis after undergoing elective intubation after the grafting of burns of the face, neck, and upper extremity. The tracheitis resulted in severe upper airway obstruction that required tracheal dilatation and sequential bronchoscopic excisions of granulation tissue. The patient also developed a brachial plexus neuropathy that was most likely related to herpetic infection. (J Burn Care Rehabil 1999;20:377–81)

摘要:
Acellular dermal matrix (ADM) has been used as a dermal substitute for the treatment of deep burns, but the availability of cadaver skin for the production of ADM is limited. The usefulness of porcine ADM as a xenogeneic dermal substitute in rats was studied. With the use of Dispase II (Boehringer Mannheim, Indianapolis, Ind) and Triton X-100 (US Biochemicals, Cleveland, Ohio), xenogeneic ADM was prepared from commercially available, cryopreserved porcine skin, and allogeneic ADM from the rats was also prepared. Four full-thickness injuries 225 mm2in size were created on the dorsum of each rat. One of these wounds was treated with xenogeneic ADM and 1 was treated with allogeneic ADM, and immediately a 0.005-in thick split-thickness skin graft was placed over the ADM. The other 2 wounds were covered with 0.005− or 0.017-in thick split-thickness skin grafts alone. The wounds were evaluated macro- and microscopically 10, 14, 20, and 30 days after grafting. At 30 days after grafting, contraction of the wounds that contained xenogeneic ADM was significantly greater than that of the wounds that contained allogeneic ADM. Graft take was poor in the wounds that contained xenogeneic ADM at 14 days after surgery and moderately good in those that contained allogeneic ADM. The use of thick autografts resulted in the best wound healing, whereas the use of thin autografts resulted in considerable wound contraction. Allogeneic ADM diminished this contraction, but wound healing was significantly worsened when xenogeneic ADM was used. (J Burn Care Rehabil 1999;20:382–90)

摘要:
Respiratory failure that requires endotracheal intubation is an uncommon but potentially fatal complication of scald burns in children. Because scalds are rarely associated with a direct pulmonary injury, the pathophysiology of respiratory failure is unclear. A possible mechanism may be upper airway edema, diminished pulmonary compliance secondary to fluid resuscitation, or both. To identify an at-risk population for intubation after a scald injury, the hospital courses of 174 consecutive patients under the age of 14 years who were admitted after a scald injury to a single burn center during a 6-year period were examined. Seven of these patients (4%) required endotracheal intubation. No patient older than 2.8 years or who had a scald injury that covered less than 19% of the total body surface area required intubation. Patients who required intubation were younger (mean age, 1.4 vs 2.8 years,P< .001), had a larger mean burn size (29.9% vs. 12.3% total body surface area,P< .001), and required more fluid resuscitation (7.66 vs. 4.07 cc/kg per percentage of total body surface area burned,P< .001) than patients who did not require intubation. Examination of the adequacy of resuscitation revealed that the intubated patients had an average hourly urine output of 0.84 cc/kg during the first 24 hours, suggesting that resuscitation was not excessive. Multivariate analysis demonstrated that both larger burn size (P= .041) and younger age (P= .049) were independent predictors of the need for intubation. Young patients with large body surface area burns that required large volumes of resuscitation comprise an at-risk group for respiratory failure after a scald injury. Increased vigilance is merited during the resuscitation of these patients. (J Burn Care Rehabil 1999;20:391–9)
