A Randomized Trial of Enteral Glutamine for Treatment of Burn Injuries.

BACKGROUND: Glutamine is thought to have beneficial effects on the metabolic and stress response to severe injury. Clinical trials involving patients with burns and other critically ill patients have shown conflicting results regarding the benefits and risks of glutamine supplementation. METHODS: In a double-blind, randomized, placebo-controlled trial, we assigned patients with deep second- or third-degree burns (affecting ≥10% to ≥20% of total body-surface area, depending on age) within 72 hours after hospital admission to receive 0.5 g per kilogram of body weight per day of enterally delivered glutamine or placebo. Trial agents were given every 4 hours through a feeding tube or three or four times a day by mouth until 7 days after the last skin grafting procedure, discharge from the acute care unit, or 3 months after admission, whichever came first. The primary outcome was the time to discharge alive from the hospital, with data censored at 90 days. We calculated subdistribution hazard ratios for discharge alive, which took into account death as a competing risk. RESULTS: A total of 1209 patients with severe burns (mean burn size, 33% of total body-surface area) underwent randomization, and 1200 were included in the analysis (596 patients in the glutamine group and 604 in the placebo group). The median time to discharge alive from the hospital was 40 days (interquartile range, 24 to 87) in the glutamine group and 38 days (interquartile range, 22 to 75) in the placebo group (subdistribution hazard ratio for discharge alive, 0.91; 95% confidence interval [CI], 0.80 to 1.04; P = 0.17). Mortality at 6 months was 17.2% in the glutamine group and 16.2% in the placebo group (hazard ratio for death, 1.06; 95% CI, 0.80 to 1.41). No substantial between-group differences in serious adverse events were observed. CONCLUSIONS: In patients with severe burns, supplemental glutamine did not reduce the time to discharge alive from the hospital.

When to Admit to Observation: Predicting Length of Stay for Anticoagulated Elderly Fall Victims.

BACKGROUND: Geriatric patients who fall while taking an anticoagulant have a small but significant risk of delayed intracranial hemorrhage requiring observation for 24 h. However, the medical complexity associated with geriatric care may necessitate a longer stay in the hospital. Little is known about the factors associated with a successful observational status stay (<2 d) for this population. MATERIALS AND METHODS: Elderly patients who fell while taking an anticoagulant admitted from 2012 to 2017 at an ACS level II trauma center were included in a retrospective cohort study to determine what factors were associated with a stay consistent with observational status. INCLUSION CRITERIA: age> 65 y old, negative initial head CT, and one of the following: INR>3.5 if on warfarin, GCS<14, external signs of trauma, or focal neurological deficits. RESULTS: The cohort included 369 patients. Factors associated with decreased likelihood of successful observational status included the need for services after discharge such as an extended care facility (OR 0.06, 95% CI 0.02-0.19, P < 0.001) or visiting nurse agency services (OR 0.27, 95% CI 0.10-0.75, P < 0.001), a dementia diagnosis (OR 0.17, 95% CI 0.04-0.70, P = 0.014), increasing number of medications (OR 0.91, 95% CI 0.84-0.99, P = 0.031), and the use of coumadin (OR 0.28, 95% CI 0.12-0.70, P = 0.006). CONCLUSIONS: For trauma providers, knowing your patient's medication use and particularly type of anticoagulant, comorbidities including dementia, and likely need for services after discharge will help guide the decision to admit the patient for what may be a reasonably lengthy stay versus a brief observation in the hospital for elderly fall victims on anticoagulation.

Understanding Epidemiological Trends in Geriatric Burn Injuries: A National Multicenter Analysis from NEISS 2004-2022.

Burn injuries pose a significant source of patient morbidity/mortality and reconstructive challenges for burn surgeons, especially in vulnerable populations such as geriatric patients. Our study aims to provide new insights into burn epidemiology by analyzing the largest national, multicenter sample of geriatric patients to date. Utilizing the National Electronic Injury and Surveillance System (NEISS) database (2004-2022), individuals with a "Burn" diagnosis were extracted and divided into two comparison age groups of 18-64 and 65+. Variables including sex, race, affected body part, incident location, burn etiology, and clinical outcomes were assessed between the two groups utilizing two proportion z-tests. 60,581 adult patients who sustained burns were identified from the NEISS database with 6,630 of those patients categorized as geriatric (65+). Geriatric patients had a significantly greater frequency of scald burns (36.9% vs. 35.4%; p<0.01), and third degree/full-thickness burns (10.4% vs 5.5%, p<0.01) relative to non-geriatric adult patients with most of these burns occurring at home (75.9% vs 67.4%; p<0.01). The top five burn sites for geriatric patients were the hand, face, foot, lower arm, and lower leg and the top five burn injury sources were hot water, cookware, oven/ranges, home fires, and gasoline. Geriatric patients had over two times greater risk of hospital admission (OR: 2.32, 95% CI: 2.17-2.49, p<0.01) and over five times greater risk of ED mortality (OR: 6.22, 95% CI: 4.00-9.66, p<0.01) after incurring burn injuries. These results highlight the need for stronger awareness of preventative measures for geriatric burn injuries.

Understanding the Drivers of Cost and Length of Stay in a Cohort of 21,875 Patients with Severe Burn.

Burn management has significantly advanced in the past 75 years, resulting in improved mortality rates. However, there are still over one million burn victims in the United States each year, with over 3,000 burn-related deaths annually. The impacts of individual patient, hospital, and regional demographics on length of stay (LOS) and total cost have yet to be fully explored in a large nationally representative cohort. Thus, this study aimed to examine various hospital and patient characteristics using a sample of over 20,000 patients. Inpatient data from the National Inpatient Sample from 2008 to 2015 were analyzed, and only patients with an ICD-9 code for second- or third-degree burns were included. In addition, a major operating room procedure must have been indicated on the discharge summary for patients to be included in the final dataset, ensuring that only severe burns requiring complex care were analyzed. Analysis of covariance models was used to evaluate the impact of various patient, hospital, and regional variables on both LOS and cost. The study found that skin grafts and fasciotomy significantly increased the cost of hospitalization. Having burns on the face, neck, and trunk significantly increased costs for patients with second-degree burns, while burns on the trunk resulted in the longest LOS for patients with third-degree burns. Infections in the hospital and additional procedures, such as flaps and skin grafts, also led to longer stays. The study also found that the prevalence of postoperative complications, such as electrolyte imbalance, was high among patients with burn surgery.

American Burn Association Clinical Practice Guidelines on Burn Shock Resuscitation.

This Clinical Practice Guideline (CPG) addresses the topic of acute fluid resuscitation during the first 48 hours following a burn injury for adults with burns ≥20% of the total body surface area (%TBSA). The listed authors formed an investigation panel and developed clinically relevant PICO (Population, Intervention, Comparator, Outcome) questions. A systematic literature search returned 5978 titles related to this topic and after 3 levels of screening, 24 studies met criteria to address the PICO questions and were critically reviewed. We recommend that clinicians consider the use of human albumin solution, especially in patients with larger burns, to lower resuscitation volumes and improve urine output. We recommend initiating resuscitation based on providing 2 mL/kg/% TBSA burn in order to reduce resuscitation fluid volumes. We recommend selective monitoring of intra-abdominal and intraocular pressure during burn shock resuscitation. We make a weak recommendation for clinicians to consider the use of computer decision support software to guide fluid titration and lower resuscitation fluid volumes. We do not recommend the use of transpulmonary thermodilution-derived variables to guide burn shock resuscitation. We are unable to make any recommendations on the use of high-dose vitamin C (ascorbic acid), fresh frozen plasma (FFP), early continuous renal replacement therapy, or vasopressors as adjuncts during acute burn shock resuscitation. Mortality is an important outcome in burn shock resuscitation, but it was not formally included as a PICO outcome because the available scientific literature is missing studies of sufficient population size and quality to allow us to confidently make recommendations related to the outcome of survival at this time.

Evaluating Real-World National and Regional Trends in Definitive Closure in U.S. Burn Care: A Survey of U.S. Burn Centers.

To better understand trends in burn treatment patterns related to definitive closure, this study sought to benchmark real-world survey data with national data contained within the National Burn Repository version 8.0 (NBR v8.0) across key burn center practice patterns, resource utilization, and clinical outcomes. A survey, administered to a representative sample of U.S. burn surgeons, collected information across several domains: burn center characteristics, patient characteristics including number of patients and burn size and depth, aggregate number of procedures, resource use such as autograft procedure time and dressing changes, and costs. Survey findings were aggregated by key outcomes (number of procedures, costs) nationally and regionally. Aggregated burn center data were also compared to the NBR to identify trends relative to current treatment patterns. Benchmarking survey results against the NBR v8.0 demonstrated shifts in burn center patient mix, with more severe cases being seen in the inpatient setting and less severe burns moving to the outpatient setting. An overall reduction in the number of autograft procedures was observed compared to NBR v8.0, and time efficiencies improved as the intervention time per TBSA decreases as TBSA increases. Both nationally and regionally, an increase in costs was observed. The results suggest resource use estimates from NBR v8.0 may be higher than current practices, thus highlighting the importance of improved and timely NBR reporting and further research on burn center standard of care practices. This study demonstrates significant variations in burn center characteristics, practice patterns, and resource utilization, thus increasing our understanding of burn center operations and behavior.

Infection in Elderly Burn Patients: What Do We Know?

Background: Infection is the greatest cause of mortality in burn patients. As our population ages, the need to care for elderly burn patients will increase, and with it our understanding of how infection affects older patients with burn injuries. This article presents a review of the available literature on the effect of aging on the physiologic response to burns, of the known effects of infection in the elder population, and of the contribution of underlying medical comorbidities to the outcomes for the elderly burn patient. The potential for more serious outcomes from multi-drug resistance in the elder population is also discussed. Methods: This article is a review of the available literature on infection in elderly burn patients. A literature search was performed for key words: elderly; geriatric; burn; infection; comorbidity; multi-drug resistance; central line; urinary tract infection; and burn sepsis. Relevant findings were included in each section. Results: Pre-existing conditions are common in the elderly and contribute to a higher rate of development of pneumonia, cellulitis, urinary tract infection, central line infections, and burn wound infections. Specific data pertaining to infections in the elderly burn population are scarce or confined to single-center reports. Conclusions: Because of the inherent susceptibility of the elder population to infection because of pre-existing medical conditions, immunosenescence, and potential exposure via frequent interaction with the medical system, vigilance must be maintained for preventing and treating infection in elderly burn patients. More research is needed to define the risks and extent of this increasingly important issue.

New onset squamous cell carcinoma in previous split-thickness skin graft donor site.

INTRODUCTION: Marjolin' s ulcer, an aggressive ulcerating squamous cell carcinoma, is a well-known phenomenon that occurs in chronically inflamed or scarred tissue; however, squamous cell carcinoma arising in the acute setting after tissue trauma - specifically autograft donor harvest sites for burns - is a rare, but notable event. METHODS: This case series describes three instances of squamous cell carcinoma diagnosed in split-thickness skin graft donor sites in the immediate post-operative period. Charts were reviewed in detail after at least 9 months follow-up from identification of the tumor. Detailed descriptions of each case are included. A discussion of the literature on this rare entity is included as well. RESULTS: In the three cases discussed, all were characterized clinically as painful masses arising in a recently healed donor site. Two were managed surgically with adherence to oncologic principals. One lesion regressed or fell off spontaneously. With at least 9 months follow-up, there was no evidence of recurrence. CONCLUSIONS: Very few cases of acute neoplasm in donor sites have been described in the literature. Presently, there is no dominant theory as to how these lesions arise; however, this is an entity that burn care providers, world wide should be aware of, with a low threshold for oncologic evaluation if suspected.

Use of aerosolized aminoglycosides in the treatment of Gram-negative ventilator-associated pneumonia.

BACKGROUND AND PURPOSE: Ventilator-associated pneumonia (VAP) in the surgical intensive care unit (ICU) is associated with substantial morbidity and mortality. Affected patients are at higher risk for infection with multi-drug-resistant (MDR) pathogens, often necessitating therapeutic regimens of two parenteral antibiotics. Aerosolized antibiotics achieve high alveolar concentrations and have been reported anecdotally to have value in the treatment of VAP. This study examined the role of aerosolized aminoglycosides in the treatment of VAP in surgical ICU patients. METHODS: We reviewed retrospectively the medical records of 22 patients who received aerosolized aminoglycosides in conjunction with parenteral antibiotics for VAP in the surgical ICU. Sixteen patients received inhaled tobramycin, and six received inhaled amikacin. Demographic information and data on the length of stay (LOS), mortality rate, days of antibiotic therapy, days of mechanical ventilation, and recurrence of VAP were collected. Results of bronchoscopic and sputum cultures were reviewed to identify bacterial pathogens and antimicrobial susceptibilities. RESULTS: The average duration of mechanical ventilation was 31 +/- 12 days, the mean ICU LOS was 41 +/- 13 days, and the mean hospital LOS was 71 +/- 25 days. There were three deaths. The average duration of mechanical ventilation after initiation of aerosolized antibiotics was 4.3 days. Seven patients (40%) developed recurrent pneumonia with the same pathogen, but only one had a change in antibiotic susceptibility pattern. There were no renal or pulmonary complications of aminoglycoside treatment. CONCLUSIONS: Ventilator-associated pneumonia in critically ill patients is associated with substantial morbidity, longer ICU stays, and prolonged mechanical ventilation. Along with systemic therapy, aerosolized aminoglycosides are valuable adjuncts in select patients with minimal risk of antibiotic resistance.

Is Pre-Hospital CPR a Risk Factor for Early Death in Patients Transferred to an Adult Burn Center?

BACKGROUND: Burn patients who require CPR before admission to a burn center are anecdotally known to suffer higher mortality than those who do not require pre-hospital CPR. STUDY DESIGN: A retrospective chart review identified adult patients admitted to our burn center between 2013 and 2015. Included patients met 1 or both of the following criteria: 20% or more total body surface area burned and need for intubation before admission to our facility. We sought to identify predictors of early death, late death, and survival among burn patients who underwent CPR before admission. RESULTS: Of the 80 patients meeting inclusion criteria, 17.5% underwent CPR before arrival at our facility. Seventy-nine percent of these died, compared with 29% of the patients who did not require CPR (p = 0.0005). Seventy-one percent of CPR patients died within 48 hours of admission, compared with 8% of non-CPR patients (p < 0.0001). The major predictor of death vs survival after CPR was lower initial arterial pH. CONCLUSIONS: Patients who undergo CPR before transfer to a burn center are at high risk for early death. Predictors of death and early death after CPR may include elevated initial lactate and lower initial arterial pH.

A multicenter study of preventable contact burns from glass fronted gas fireplaces.

Glass fronted gas fireplaces (GFGFs) have exterior surfaces that can reach extremely high temperatures. Burn injuries from contact with the glass front can be severe with long-term sequelae. The Consumer Product Safety Commission reported that these injuries are uncommon, whereas single-center studies indicate a much higher frequency. The purpose of this multi-institutional study was to determine the magnitude and severity of GFGF injuries in North America. Seventeen burn centers elected to participate in this retrospective chart review. Chart review identified 402 children ≤10 years of age who sustained contact burns from contact with GFGF, who were seen or admitted to the study hospitals from January 2006 to December 2010. Demographic, burn, treatment, and financial data were collected. The mean age of the study group was 16.8 ± 13.3 months. The majority suffered burns to their hands (396, 98.5%), with burns to the face being the second, much less common site (14, 3.5%). Two hundred and sixty-nine required rehabilitation therapy (66.9%). The number of GFGF injuries reported was 20 times greater than the approximately 30 injuries estimated by the Consumer Product Safety Commission's 10-year review. For the affected children, these injuries are painful, often costly and occasionally can lead to long-term sequelae. Given that less than a quarter of burn centers contributed data, the injury numbers reported herein support a need for broader safety guidelines for gas fireplaces in order to have a significant impact on future injuries.

A case of pyogenic liver abscesses in a previously healthy adolescent man.

An 18-year-old, previously healthy man admitted with abdominal pain, high-grade fevers, nausea and emesis was found to have multiple hepatic abscesses. Aspiration cultures grew Fusobacterium necrophorum, a rare bacterium causing potentially fatal liver abscesses in humans. Following sequential percutaneous drainages and narrowing of antibiotics, the patient was discharged on a 6-week antibiotic course and showed no signs of infection. A week after presentation it was discovered that he had experienced upper respiratory symptoms and sore throat prior to presentation. Because oropharyngeal infections are a potential source of bacteremia, they must be considered in the differential diagnosis of patients presenting with hepatic abscesses and no evidence of immunocompromise.

Characteristics of patients with injury secondary to smoking on home oxygen therapy transferred intubated to a burn center.

BACKGROUND: The aim of this study was to compare outcomes of patients who sustained burn and ostensible inhalation injuries while on home oxygen therapy with those suffering equivalent injuries via other mechanisms. STUDY DESIGN: Between December 2002 and January 2006, 109 burn patients were transferred to our center intubated. Their charts were retrospectively reviewed. Patients who sustained injuries while on home oxygen therapy were age and total body surface area matched to patients with inhalation and burn injuries secondary to other mechanisms. RESULTS: Fourteen of 109 patients were injured while smoking on home oxygen therapy (15.26%). All 14 had COPD. Mean age was 63 years (range 53 to 77 years) and average total body surface area burned was 4% (range 0% to 10%). Charges for the 14 hospitalizations totaled $1,097,860 ($8,003 to $284,835; mean $78,418 per admission). Average time to extubation was 5.7 ± 10.2 days and average length of stay was 11.4 ± 15.2 days. No significant differences in the average time to extubation, length of stay, cost of hospitalization, or clinical signs of inhalation injury (ie, soot and edema in the pharynx) were noted between our series and the control group. CONCLUSIONS: Injury secondary to smoking on home oxygen therapy is a perennial problem, and guidelines for prescribing home oxygen therapy for smokers should be reassessed. Despite underlying lung disease, patients in our series did as well as patients without COPD who sustained similar injuries.

Use of continuous local anesthetic infusion in the management of postoperative split-thickness skin graft donor site pain.

Donor sites from split-thickness skin grafts (STSG) impose significant pain on patients in the early postoperative period. We report the use of continuous local anesthetic infusion as a method for the management of postoperative STSG donor site pain. Patients undergoing single or dual, adjacent STSG harvest from the thigh (eight patients) or back (one patient) were included in this study. Immediately after STSG harvest, subcutaneous catheters were placed for continuous infusion of local anesthetic. Daily donor site-specific pain severity scores were prospectively recorded in nine patients receiving local anesthetic infusion. Patient characteristics, technical aspects, and postoperative complications were identified in the study. The thigh was the anatomic location chosen for most donor sites. A single catheter was placed for donor sites limited to 4 inches in width or less. A dual catheter system was used for those wider than 4 inches. An elastomeric pump delivered continuously a total of 4 ml/hr of a solution of 0.5% bupivacaine. The average anesthetic infusion duration was 3.1 days. A substantial decrease in worst, least, and average donor site pain scores was found from the first 24 hours to the second postoperative day in our patients, a treatment trend that continued through postoperative day 3. One patient developed minor anesthetic leakage from the catheter insertion site; and in three cases, accidental dislodgement of the catheters occurred. There were no cases of donor site secondary infection. All donor sites were completely epithelialized at 1-month follow-up. Continuous local anesthetic infusion is technically feasible and may represent an option for postoperative donor site pain control after STSG harvesting. Relative cost-benefit of the technique remains to be determined.
