Belaunzaran, M, Raslan, S, Ali, A, Newsome, K, McKenney, M, Elkbuli, A
The American surgeon. 2022;(1):10-19
Abstract
Shock is a sequelae in trauma and burn patients that substantially increases the risk for morbidity and mortality. The use of resuscitation endpoints allows for improved management of these patients, with the potential to prevent further morbidity/mortality. We conducted a review of the current literature on the efficacy of hemodynamic, metabolic, and regional resuscitation endpoints for use in trauma and burn patients. Hemodynamic endpoints included mean arterial pressure (MAP), heart rate (HR), urinary output (UO), compensatory reserve index (CRI), intrathoracic blood volume, and stroke volume variation (SVV). Metabolic endpoints measure cellular responses to decreased oxygen delivery and include serum lactic acid (LA), base deficit (BD), bicarbonate, anion gap, apparent strong ion difference, and serum pH. Mean arterial pressure, HR, UO, and LA are the most established markers of trauma and burn resuscitation. The evidence suggests LA is a superior metabolic endpoint marker. Newer resuscitation endpoint technologies such as point-of-care ultrasound (PoCUS), thromboelastography (TEG), and rotational thromboelastometry (ROTEM) may improve patient outcomes; however, additional research is needed to establish the efficacy in trauma and burn patients. The endpoints discussed have situational strengths and weaknesses and no single universal resuscitation endpoint has yet emerged. This review may increase knowledge and aid in guideline development. We recommend clinicians continue to integrate multiple endpoints with emphasis on MAP, HR, UO, LA, and BD. Future investigation should aim to standardize endpoints for each clinical presentation. The search for universal and novel resuscitation parameters in trauma and burns should also continue.

Impact of Adding Protein Supplementation to Exercise Training on Lean Body Mass and Muscle Strength in Burn Patients.
Badawy, MM, Allam, NM
Journal of burn care & research : official publication of the American Burn Association. 2021;(5):968-974
Abstract
Protein catabolism is a common complication after burn injury, leading to a loss of muscle mass and a decrease in muscle strength. The present study was aimed to evaluate the efficacy of combining exercise training with protein supplementation on lean body mass and muscle strength in patients with severe burn. Sixty participants with severe burn >30% of TBSA were randomly distributed into four equal groups of 15 participants per group. Group A (Exercise and Protein) received oral protein supplementation (Inkospor X-TREME; 1.5-2.0 g/kg/d), exercise program, and traditional burn care; group B (Protein) received oral protein supplementation and traditional burn care; group C (Exercise) received exercise program and traditional burn care; and group D (Control) received traditional burn care. Lean body mass was measured using dual-energy x-ray absorptiometry, whereas muscle strength was measured using Biodex 3 Dynamometer System before treatment and 12 weeks after treatment. A significant increase in lean body mass was found in group A compared with that of group B, group C, and group D post-treatment (P < .001). Also, a significant increase was recorded in peak torque of group A compared with that of group B, group C, and group D post-treatment (P < .001). Exercise training can significantly increase lean body mass and peak torque. Protein supplementation can significantly increase lean body mass but cannot significantly increase muscle strength, whereas protein + exercise group has a great impact on lean body mass and muscle power than exercise group and protein group in burn patients.

Saeg, F, Orazi, R, Bowers, GM, Janis, JE
Plastic and reconstructive surgery. 2021;(1):226-238
Abstract
BACKGROUND The role of nutritional intervention in wound care has been a topic of controversy. Although the efficacy of macronutrient supplementation has been well described, there is a paucity of evidence and no official recommendation regarding the use of vitamins and minerals to optimize wound healing. This is the first review of vitamin and mineral wound intervention that systematically summarizes the literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and distills the evidence by wound type. METHODS In this comprehensive review, the authors outline the nutrients and delivery methods used in the identified studies, analyze reported treatment outcomes, summarize nutrient effectiveness, and propose evidence-based conclusions to improve wound healing outcomes and enhance the consistency of nutritional intervention in wound care. RESULTS Thirty-six studies with a combined total of 2339 patients investigated the use of oral, topical, or intravenous vitamin and/or mineral supplementation for treatment of the following wound types: burn wounds (n = 3), pressure ulcers (n = 7), diabetic ulcers (n = 4), venous ulcers (n = 7), digital ulcers (n = 1), skin incisions (n = 9), hypertrophic scars (n = 4), and sinonasal wounds (n = 1). Improved outcomes were reported in patients with burn wounds receiving vitamins A, B1, B6, B12, D, and E and zinc, calcium, copper, magnesium, selenium, and zinc; patients with pressure ulcers receiving vitamin C and zinc; patients with diabetic ulcers receiving vitamin A, B9, D, and E; patients with venous ulcers receiving zinc; and patients with hypertrophic scars receiving vitamin E. CONCLUSIONS Based on the high-level data provided in this review, the use of specific nutritional interventions may improve the outcome of certain wound types. Further investigation is warranted to draw definitive conclusions.

Medical grade honey for the treatment of paediatric abdominal wounds: a case series.
Smaropoulos, E, Cremers, NA
Journal of wound care. 2020;(2):94-99
Abstract
OBJECTIVE Children are at high risk of injuries and wounds. The application of medical grade honey is a promising approach to improving the healing of wounds of various origin and severity. However, the use of medical grade honey in young paediatric patients remains limited. The aim of this study is to show the safety, efficacy and usefulness of medical grade honey in abdominal wounds, of different causes, in paediatric patients. METHOD This was a prospective, observational case series evaluating five young infants with abdominal wounds at the General Hospital in Thessaloniki. All wounds were treated in the same manner with daily medical grade honey applied to the wound area and closely monitored. RESULTS All treated wounds rapidly presented granulation tissue formation and underwent re-epithelialisation. Peripheral oedema and inflammation decreased upon initial application. Necrotic tissue was effectively debrided when present. Slough was removed and no signs of infection were detected, irrespective of initial wound presentations. Scar formation was minimal and the full range of motion was preserved in all cases. CONCLUSION Based on this case study, medical grade honey is safe and effective in treating different abdominal wounds, including infected or dehisced wounds as well as burns. The easy application and broad applicability make medical grade honey recommendable as a first-line treatment in paediatric patients.

Abstract
BACKGROUND Burn injuries are an important health problem. They occur frequently in the head and neck region. The face is the area central to a person's identity that provides our most expressive means of communication. Topical interventions are currently the cornerstone of treatment of burns to the face. OBJECTIVES To assess the effects of topical interventions on wound healing in people with facial burns of any depth. SEARCH METHODS In December 2019 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. SELECTION CRITERIA Randomised controlled trials (RCTs) that evaluated the effects of topical treatment for facial burns were eligible for inclusion in this review. DATA COLLECTION AND ANALYSIS Two review authors independently performed study selection, data extraction, risk of bias assessment and GRADE assessment of the certainty of the evidence. MAIN RESULTS In this first update, we included 12 RCTs, comprising 507 participants. Most trials included adults admitted to specialised burn centres after recent burn injuries. Topical agents included antimicrobial agents (silver sulphadiazine (SSD), Aquacel-Ag, cerium-sulphadiazine, gentamicin cream, mafenide acetate cream, bacitracin), non-antimicrobial agents (Moist Exposed Burn Ointment (MEBO), saline-soaked dressings, skin substitutes (including bioengineered skin substitute (TransCyte), allograft, and xenograft (porcine Xenoderm), and miscellaneous treatments (growth hormone therapy, recombinant human granulocyte-macrophage colony-stimulating factor hydrogel (rhGMCS)), enzymatic debridement, and cream with Helix Aspersa extract). Almost all the evidence included in this review was assessed as low or very low-certainty, often because of high risk of bias due to unclear randomisation procedures (i.e. sequence generation and allocation concealment); lack of blinding of participants, providers and sometimes outcome assessors; and imprecision resulting from few participants, low event rates or both, often in single studies. Topical antimicrobial agents versus topical non-antimicrobial agents There is moderate-certainty evidence that there is probably little or no difference between antimicrobial agents and non-antimicrobial agents (SSD and MEBO) in time to complete wound healing (hazard ratio (HR) 0.84 (95% confidence interval (CI) 0.78 to 1.85, 1 study, 39 participants). Topical antimicrobial agents may make little or no difference to the proportion of wounds completely healed compared with topical non-antimicrobial agents (comparison SSD and MEBO, risk ratio (RR) 0.94, 95% CI 0.68 to 1.29; 1 study, 39 participants; low-certainty evidence). We are uncertain whether there is a difference in wound infection (comparison topical antimicrobial agent (Aquacel-Ag) and MEBO; RR 0.38, 95% CI 0.12 to 1.21; 1 study, 40 participants; very low-certainty evidence). No trials reported change in wound surface area over time or partial wound healing. There is low-certainty evidence for the secondary outcomes scar quality and patient satisfaction. Two studies assessed pain but it was incompletely reported. Topical antimicrobial agents versus other topical antimicrobial agents It is uncertain whether topical antimicrobial agents make any difference in effects as the evidence is low to very low-certainty. For primary outcomes, there is low-certainty evidence for time to partial (i.e. greater than 90%) wound healing (comparison SSD versus cerium SSD: mean difference (MD) -7.10 days, 95% CI -16.43 to 2.23; 1 study, 142 participants). There is very low-certainty evidence regarding whether topical antimicrobial agents make a difference to wound infection (RR 0.73, 95% CI 0.46 to 1.17; 1 study, 15 participants). There is low to very low-certainty evidence for the proportion of facial burns requiring surgery, pain, scar quality, adverse effects and length of hospital stay. Skin substitutes versus topical antimicrobial agents There is low-certainty evidence that a skin substitute may slightly reduce time to partial (i.e. greater than 90%) wound healing, compared with a non-specified antibacterial agent (MD -6.00 days, 95% CI -8.69 to -3.31; 1 study, 34 participants). We are uncertain whether skin substitutes in general make any other difference in effects as the evidence is very low certainty. Outcomes included wound infection, pain, scar quality, adverse effects of treatment and length of hospital stay. Single studies showed contrasting low-certainty evidence. A bioengineered skin substitute may slightly reduce procedural pain (MD -4.00, 95% CI -5.05 to -2.95; 34 participants) and background pain (MD -2.00, 95% CI -3.05 to -0.95; 34 participants) compared with an unspecified antimicrobial agent. In contrast, a biological dressing (porcine Xenoderm) might slightly increase pain in superficial burns (MD 1.20, 95% CI 0.65 to 1.75; 15 participants (30 wounds)) as well as deep partial thickness burns (MD 3.00, 95% CI 2.34 to 3.66; 10 participants (20 wounds)), compared with antimicrobial agents (Physiotulle Ag (Coloplast)). Miscellaneous treatments versus miscellaneous treatments Single studies show low to very low-certainty effects of interventions. Low-certainty evidence shows that MEBO may slightly reduce time to complete wound healing compared with saline soaked dressing (MD -1.7 days, 95% CI -3.32 to -0.08; 40 participants). In addition, a cream containing Helix Aspersa may slightly increase the proportion of wounds completely healed at 14 days compared with MEBO (RR 4.77, 95% CI 1.87 to 12.15; 43 participants). We are uncertain whether any miscellaneous treatment in the included studies makes a difference in effects for the outcomes wound infection, scar quality, pain and patient satisfaction as the evidence is low to very low-certainty. AUTHORS' CONCLUSIONS There is mainly low to very low-certainty evidence on the effects of any topical intervention on wound healing in people with facial burns. The number of RCTs in burn care is growing, but the body of evidence is still hampered due to an insufficient number of studies that follow appropriate evidence-based standards of conducting and reporting RCTs.

The use of moist exposed burn ointment (MEBO) for the treatment of burn wounds: a systematic review.
Mabvuure, NT, Brewer, CF, Gervin, K, Duffy, S
Journal of plastic surgery and hand surgery. 2020;(6):337-343
Abstract
Moist exposed burn ointment (MEBO) is an oil-based herbal paste, purported to be efficacious in managing burn wounds and more commonly used in Asia and the Middle East. A PRISMA-compliant systematic review was performed to analyse the evidence for the use of MEBO on burn wounds. Wound healing rate was the primary outcome of interest. PubMed-listed randomised controlled trials (RCTs) comparing the efficacy of MEBO with placebo, standard care or other therapies in the treatment of partial thickness burns in adults and children were eligible for inclusion (November 2019). Six RCTs were eligible. The majority of trials comparing wound healing between MEBO and SSD favoured MEBO (two of three). There may be improved healing in MEBO-treated wounds vs. those treated with povidone-iodine + bepanthenol cream. There was no difference between MEBO and Acquacel Ag, but Helix Aspersa had faster healing rates than MEBO. However, all evidence was from moderately to poorly reported trials with a high risk of bias, thereby limiting the strength of this evidence. In conclusion, the evidence for MEBO in English-language literature was poor and inconsistent with respect to wound healing rate and analgesis compared to 1% SSD, Acquacel Ag, Helix aspersa cream and povidone-iodine + bepanthenol cream. Blinded RCTs comparing MEBO to both placebo and other common topical treatments may further improve the confidence in concluding their analysis. There is some evidence that MEBO is as safe as its comparators as shown by the low complication rate.

Nutritional therapy among burn injured patients in the critical care setting: An international multicenter observational study on "best achievable" practices.
Chourdakis, M, Bouras, E, Shields, BA, Stoppe, C, Rousseau, AF, Heyland, DK
Clinical nutrition (Edinburgh, Scotland). 2020;(12):3813-3820
Abstract
BACKGROUND & AIMS Burn patients pose a number of clinical challenges for doctors and dietitians to achieve optimal nutrition practice. The objective of this study was to describe nutrition practices in burn center intensive care units (ICUs) compared to the most recent ESPEN and SCCM/ASPEN guidelines (hereafter referenced as "the Guidelines") and highlight the variation in practice and what is "best achievable." METHODS In 2014-15, we prospectively enrolled 283 mechanically ventilated patients who were admitted to one of 14 burn ICUs for at least 72 h. Data collected included information on the estimation of energy and protein requirements, their actual delivery as well as route and time of feeding, and administration of micronutrients. We describe site practices and data per patient-day. RESULTS Adherence to the Guidelines for the use of enteral nutrition (EN) over parenteral nutrition (PN) was 90.5% of patient-days (site range 79.2%-97.0%). However, adherence to the Guidelines for the measurement of energy requirements was 6.0% of patient-days (site range 0.0%-93.3%), supplementation with glutamine took place in 22.4% of patient-days (site range 0.0%-61.8%). Provision of 80% of energy requirements within 48-72 h was achieved in 35.3% of patients (site range 0.0%-80.0%), and provision of 80% of protein needs within 48-72 h was achieved in 34.3% of patients (site range 0.0%-80.0%). Average nutritional adequacy was 64.9 ± 40.0% for energy (best site: 80.2%, worst site: 42.0%) and 65.6 ± 42.1% for protein (best site: 87.3%, worst site: 43.6%). CONCLUSION The present findings indicate that despite high adherence to providing EN over PN, there is still a large gap between many recommendations and clinical practice, and the achievement of nutrition goals for patients in burn centers is suboptimal.

Safety and Tolerance of Intraoperative Enteral Nutrition Support in Pediatric Burn Patients.
Sunderman, CA, Gottschlich, MM, Allgeier, C, Warden, G
Nutrition in clinical practice : official publication of the American Society for Parenteral and Enteral Nutrition. 2019;(5):728-734
Abstract
BACKGROUND Multiple surgical procedures required by patients with extensive thermal injuries impedes delivery of adequate nutrition support, leading to caloric deficits, weight loss, delayed wound healing, and increased length of stay. The standard practice at our institution for >20 years has been to continuously infuse postpyloric enteral nutrition (EN) during surgery. The purpose of this review was to examine the safety and efficacy of intraoperative EN support. METHODS A retrospective chart review of pediatric patients with burn injuries >30% total body surface area provided a 20-year (1995-2014) safety assessment associated with intraoperative feeding along with an evaluation of gastrointestinal tolerance and efficacy. Continuous variables were summarized by mean and SD, whereas categorical variables were summarized by counts and percentages. RESULTS The 20-year review confirmed the safety of intraoperative feeding, as the assessment of 434 patients revealed no incidence of aspiration. Patients were successfully fed during an average of 8.4 ± 6.5 surgical procedures and received EN support for a mean of 49.9 ± 31.7 days. Uninterrupted nutrition delivery was well tolerated with minimal gastrointestinal intolerance. Patients achieved an average nitrogen balance of 3.1 ± 2.8 and 70% maintained ±10% of their body weight at time of discharge. CONCLUSION EN has been safely provided with marginal intolerance during surgical procedures over the past 20 years. Continuous nutrition support with negligible interruption is integral to meet nutrient needs for wound healing, preservation of weight and nutrition parameters, and optimize length of stay in pediatric patients with extensive thermal injuries.

Thrombin generation in patients with severe thermal injury.
Wiegele, M, Schaden, E, Koch, S, Bauer, D, Krall, C, Adelmann, D
Burns : journal of the International Society for Burn Injuries. 2019;(1):54-62
Abstract
BACKGROUND Severe burns can induce a hypercoagulable state which is not depicted in conventional coagulation assays. The thrombin generation assay allows global assessment of coagulation and can identify hypercoagulability. We report changes in thrombin generation in patients after severe burn injury. METHODS We measured TGA, rotational thrombelastometry and conventional assays in 20 consecutive patients with a total body surface area burned of >20% over a 2-week period: the day after burn trauma (A), the morning after surgical excision of burn wounds (B) and on post-admission days 7 (C) and 14 (D). RESULTS Thrombin generation assay showed a procoagulatory state: there was an increase in the velocity of thrombin generation (increase in time to peak of +13%, increase in velocity index of +22%), and peak amount of thrombin (+25%) between days A and B. All parameters reached their highest levels on day C and returned towards normal on day D. Rotational thrombelastometry showed a hypercoagulable state with an increase in clot firmness and alpha angle. Conventional coagulation tests remained within reference values. CONCLUSIONS In the first two weeks following burn, both the thrombin generation assay and rotational thrombelastometry show a hypercoagulable state, while conventional coagulation tests remain normal.

Pediatric enteral nutrition therapy for burn victims: when should it be initiated?
Valentini, M, Seganfredo, FB, Fernandes, SA
Revista Brasileira de terapia intensiva. 2019;(3):393-402
Abstract
OBJECTIVE To review the scientific evidence regarding the initiation of enteral nutrition in the pediatric burn population. METHODS This study was a systematic review and meta-analysis of randomized clinical trials comparing early enteral nutrition and late enteral nutrition in individuals aged 1 month to 18 years with burns. The MEDLINE/PubMed, Embase and Cochrane Library databases were searched using the terms "burns", "fires", "child nutrition disorders", "nutritional support" and related terms. RESULTS Three articles that included a total of 781 patients were identified. There was no significant difference in the mortality rate between the early and late groups (OR = 0.72, 95%CI = 0.46 - 1.15, p = 0.17). Patients who received early enteral nutrition had a 3.69-day reduction in the length of hospital stay (mean difference = -3.69, 95%CI = -4.11 - -3.27, p < 0.00001). There was a higher incidence of diarrhea and vomiting and decreased intestinal permeability in the early group. This group also presented higher a serum insulin concentration and insulin/glucagon ratio as well as lower caloric deficit and weight loss when compared to the control group. CONCLUSION Analysis of the different intragroup variables suggests the importance of starting nutritional support early. Considering the number of pediatric burn patients, there is a need for robust studies with greater scientific impact.
