摘要:
The plasma clearance, plasma half-life, and apparent volume of distribution of morphine during anesthesia and surgery were determined in seven patients with burns and compared with seven age-matched control subjects. The burn group had a significantly lower clearance, longer terminal half-life, and smaller volume of distribution than the control group. The clearance was 12 ± 2 ml/min/kg, the half-life was 123 ± 24 minutes, and the volume of distribution was 2.2 ± 0.4 L/kg for the subjects with burns compared with 25 ± 3 ml/min/kg, 89 ± 18 minutes, and 3.2 ± 0.8 L/kg for the control subjects (p< 0.001, < 0.02, and < 0.02, respectively). These data contrast with the theory that patients with burns have a tolerance to narcotics and suggest the need for further study of the pharmacologic effects of burn injury and surgery.

摘要:
Previous studies have found that acute ethanol ingestion before burn injury caused further impairment of mitogenic response of B lymphocytes compared with burn injury alone. The principal role of B lymphocytes is immunoglobulin production. This study was designed to determine the effect of acute ethanol ingestion on circulating immunoglobulin levels before injury. Serum concentrations of IgG, IgM, and IgA in rats were measured with the use of radial immunodiffusion plates at 4 days after a 30% burn injury in animals that had received a single ingestion of 3.0 ml ethanol per kilogram of body weight. The immunoglobulin levels were compared with appropriate controls. A 30% burn injury produced significant decreases in serum IgG and IgA levels but not in IgM levels, whereas acute ethanol ingestion only decreased IgA levels. Acute ethanol ingestion before injury did not induce any further significant decrease than did burn injury alone.

摘要:
Nutritional support is provided to children after severe burn injuries in amounts derived from empirical formulas or measurements of resting energy expenditure. To scrutinize these methods, indirect calorimetry measurements were performed on 74 survivors of burns (≥40% total body surface area) and compared to their actual caloric intake, percent weight change, and optimal caloric requirements formulated from the Curreri and Shriners' equations. These parameters showed that in spite of an initial deficit in actual caloric intake as compared to formulated goals, weight was maintained, whereas resting energy expenditures ranged from 30% to 40% below the actual caloric intake. Furthermore, a subgroup of patients (n= 42) who met ± 20% of their formulated needs were stratified by extent of burn; this illustrated a significant weight gain in the more severely burned children. In conclusion, nutritional formulas in popular use overestimate caloric requirements in severe burns, whereas resting energy expenditure measurements require an additional factor of 30% to maintain body weight.

摘要:
A previous study indicated that formulas for determining caloric requirements of severely burned children overestimated their needs. This study was undertaken to determine the caloric intake required to maintain weight in patients under 12 years of age with burns over more than 30% total body surface area. The 102 patients studied were divided into two groups according to weight changes. A comparison of the actual caloric intakes of these groups was conducted. Multivariate regression analysis indicated that body surface area in square meters and burn surface area were significant predictors of caloric requirements to maintain weight in these patients. It was determined that 1800 kcal was a plausible value for the calories per body surface area. Therefore the regression was formed with 1800 kcal as the multiplier of body surface area, and the multiplier of burn surface area was estimated. The resulting formula provides 1300 kcal/m2burned, which is 900 kcal/m2burned less than our previously suggested formula.

摘要:
Cyclosporine A (CsA) immunosuppression was used in three patients with massive burns to prolong skin allograft survival. Cyclosporine A kinetic studies in patients with burns revealed markedly accelerated blood clearance and high variability in drug absorption when compared with studies in renal transplantation patients. Doses required to maintain therapeutic levels varied widely. While patients were receiving adequate maintenance therapy with CsA immunosuppression the allograft was tightly adherent without gross or microscopic rejection and was indistinguishable from autograft. Ultimately, patients' wounds were permanently covered with sequential autografts by recropping limited donor sites. There were no unusual septic complications, although prophylaxis for opportunistic infections was used. The disadvantage of allograft use is its early rejection and obligatory replacement until permanent coverage with autograft can be accomplished. Cyclosporine A can prolong allograft survival and allow autograft coverage from limited donor sites in a sequential fashion. This may lead to increased survival in patients with massive burns.

摘要:
A blood culture is an essential laboratory procedure necessary to confirm a septic episode. However, it is important to collect the blood sample at the appropriate time with an acceptable technique. The standard method is to collect at least 5 to 10 ml blood per culture bottle from patients with fevers. However, this volume of blood is an unrealistic amount to take from the frequently febrile pediatric patient. Alternatively, the pediatric blood culture bottle allows the collection of 1 ml blood per bottle to perform the same evaluation. We evaluated the two techniques of blood-culture collection over a 9-month period and compared the results between adult and pediatric blood culture bottles. Seventy-six patients, from November 1988 through February 1989, had blood cultures performed with the adult culture bottles, which produced a total of 1314 samples. A total of 113 patients, from March through July 1989, had blood cultures performed with the pediatric culture bottles, which produced a total of 758 samples. Percent recovery for the adult bottles versus the pediatric bottles was 13.95% versus 22.8% (p< 0.0001). Since the amount of blood necessary to isolate an infectious agent is critical not only for laboratory identification but also for the volume of blood of pediatric patients, these data clearly establish the efficacy of pediatric blood culture bottles and the utilization of smaller amounts of blood. Not only did this approach significantly enhance organism recovery rate, but it may well be more cost-effective because fewer cultures need to be performed to isolate the infectious organism.

摘要:
A survey was done to determine how burn wound microbial monitoring is performed and how topical antimicrobial agents are employed. The survey was sent to 90 burn-care facilities, which comprised most of the major burn centers in the United States. The survey contained questions concerning frequency and techniques of wound monitoring, personnel involved in monitoring, as well as questions about how decisions were made to initiate topical antimicrobial therapy, which agents were selected, and how they were administered. Sixty of 90 facilities (66%) responded to the survey. Although there were few areas of unanimous agreement, several trends did emerge. Most facilities monitored burn wounds for microbes (92%). Wound monitoring was typically done at least twice weekly by either surface swab or quantitative biopsy. Nursing staff played a significant role in specimen collection in 69% of facilities and were solely responsible for obtaining biopsy specimens in 29% of facilities that used biopsies exclusively. All responding facilities used topical antimicrobial agents; silver sulfadiazine was the most popular (95%). Only 33% of facilities surveyed had their own laboratory for microbial monitoring. Rapid techniques for early diagnosis of wound sepsis were used in 20% of units, and topical antimicrobial testing was used in 17% of facilities surveyed.

摘要:
Thermally injured mice that were given intraperitoneal injections of murine cytomegalovirus (MCMV) appeared to be clinically septic and to have increased mortality rates. To evaluate the possible role of MCMV infection in promoting bacterial translocation in burned mice, mesenteric lymph nodes were cultured from two strains of mice (BALB/c and CBA) that were given thermal injuries alone, MCMV alone, or both. BALB/c mice injected with 5 × 105plaque-forming units MCMV following a 15% to 16% total body surface area scald injury had increased incidence of positive mesenteric lymph node cultures compared with other groups. No intestinal mucosal histologies, mucosal dry weights, or wet-to-dry weight ratios in any animals were abnormal. Differences in cecal bacterial concentrations were not observed. Murine cytomegalovirus infection appears to enhance bacterial translocation in this model.

摘要:
Bacterial colonization and infection of wounds in seriously burned patients often comes from the patient's indigenous bowel flora. A prospective randomized clinical trial that involved 30 patients with 20% or greater total body surface area burns was undertaken to evaluate the use of a standard antibiotic bowel preparation in the delay or prevention of bacterial colonization of the burn wound and sepsis. Certain enteric bacteria were seen less frequently in the treated group (Enterobacterorganisms), but other bacteria appeared more often in the treated group (Proteusorganisms and enterococci). The average time of colonization of the burn wounds was 6.1 days in the treated group and 6.7 days in the control group. Blood cultures were positive for enteric organisms earlier in the treatment group. Pseudomonads appeared earlier in the wound and blood cultures of the treated group than in the control group. The effect of antibiotic bowel suppression in patients with burns is varied and unpredictable. The bowel preparation may select certain organisms and lead to earlier colonization of the wounds. Overall outcome and survival was not improved by the use of an antibiotic bowel preparation in these patients.
