Effectiveness of platelet rich plasma in burn wound healing: A systematic review and meta-analysis
The Journal of dermatological treatment. 2020;:1-25
Background: To evaluate the efficacy of platelet-rich plasma (PRP) in the treatment of burn wounds.Methods: A comprehensive literature survey was conducted in electronic medical journal databases to identify studies that examined the effect of PRP treatment to burn wounds and meta-analyses of mean differences (MD) standardized MD, or odds ratios (OR) were performed.Results: The percentage of graft take was not significantly different between PRP-treated and control wound areas. Healing rate was significantly better in PRP-treated wounds. Healing time was also significantly less in PRP-treated wounds. There was no significant difference between PRP-treated and control wound areas in epithelialization, or in the incidence of adverse events. Incidence of infection was also not different between PRP-treated and control wound areas. Scar assessment score was significantly better in PRP-treated than in control wound areas.Conclusion: PRP treatment to burn wounds is found to improve healing. Variations in study design and sample size, types of wounds, PRP preparation protocols, and high risk of bias in some of the included studies may have impact on these outcomes.
Fibrin tissue sealant and minor skin grafts in burn surgery: A systematic review and meta-analysis
Journal of plastic, reconstructive & aesthetic surgery : JPRAS. 2019
BACKGROUND The indications for use of fibrin glue in skin grafting burn patients remains understudied. The purpose of this study is to review the efficacy of fibrin tissue sealant in skin graft adherence, establish guidelines for use of fibrin tissue sealant, and review the cost effectiveness of fibrin glue. METHODS Publications with the following criteria were included: comparative human studies, autologous skin grafts, and autologous or commercial fibrin sealant. Outcomes assessed included evidence of engraftment, wound closure, rates of hematoma/seroma, graft loss and infection. Meta-analysis obtained pooled odds ratios for outcomes of interest. Cost analysis was performed using data available in the literature. RESULTS 7 studies and 751 interventions (fibrin) and controls (staples) were included in the final analysis. 67.6% grafts with fibrin were 100% adherent by one week, vs. 55.5% (OR 1.45, p=0.086). Complete wound closure by one month was 80.2% with fibrin, vs. 73.3% (OR 1.34, p=0.187). Hematoma/seroma occurred 38.2% with fibrin, vs. 64.7% (OR 0.487, p=0.122). Graft loss was higher in the control group, 21% vs. 12.6% (OR 0.891, p=0.604). Average cost of fibrin glue was $50 per ml, and averaged costs of stapler and staple remover was $30 USD ($10-50). CONCLUSION Fibrin glue is as effective as staples for adhering skin grafts, and trends towards lower rates of hematoma/seroma. In topographically complex regions, fibrin glue may be a better choice for adherence of skin grafts.
Pediatric Toxic Shock Syndrome After a 7% Burn: A Case Study and Systematic Literature Review
Annals of plastic surgery. 2019
INTRODUCTION Toxic shock syndrome (TSS) is a life-threatening condition, which occurs in children after sustaining a burn. Often diagnosed retrospectively, many patients may not receive optimal treatment.The primary objective of this study was to evaluate a severe and complex case of TSS at our unit and subsequently conduct a Preferred Reporting for Systematic Reviews and Meta-Analyses-compliant systematic literature review, to identify cases of postthermal injury TSS and evaluate their presentation and management. CASE REPORT A 9-year-old boy with Down syndrome presented with a 7% total body surface area scald to his back and posterior head. Four days after discharge, he developed a fever. The following day, he deteriorated, becoming stridulous and unresponsive. A working diagnosis of TSS was made. The patient's intensive care stay was arduous with multiple complications, including 2 cardiac arrests. METHODS A Preferred Reporting for Systematic Reviews and Meta-Analyses-compliant systematic literature review was conducted. MEDLINE, PubMed, and Web of Science were searched using key terms "burns, thermal injury, scalds, paediatric, child, infant, neonate, toxic shock syndrome" to identify cases. Two authors independently checked each study against inclusion criteria. RESULTS The systematic literature search yielded 9 articles, identifying 40 cases. Ages ranged between 9 months and 8 years. The mean number of days' postburn patients presented with symptoms of TSS was 2.5 days (1-7 days). The most common presenting symptoms were fever (75%), rash (70%), and diarrhea, and/or vomiting (52.5%). Intravenous immunoglobulins were administered in 11 (27.5%) cases. DISCUSSION We have highlighted a case where a possible delayed diagnosis along with the immunodeficiency seen in Down syndrome may have impacted the severity of TSS. The literature review highlighted that a significant proportion of patients do not meet diagnostic criteria. CONCLUSIONS It is fundamental that appropriate diagnostic and management guidelines are developed. Furthermore, this case highlights the importance of educating patient's carers and health professionals of key symptoms to be wary of postburn.
The effect of mesenchymal stem cells combined with platelet-rich plasma on skin wound healing
Journal of Cosmetic Dermatology. 2018;17((5):):650-659
INTRODUCTION Mesenchymal stem cells (MSCs) are multipotent stem cells that have the potential of proliferation, high self-renewal, and the potential of multilineage differentiation. The differentiation potential of the MSCs in vivo and in vitro has caused these cells to be regarded as potentially appropriate tools for wound healing. After the burn, trauma or removal of the tumor of wide wounds is developed. Although standard treatment for skin wounds is primary healing or skin grafting, they are not always practical mainly because of limited autologous skin grafting. EVIDENCE ACQUISITIONS Directory of Open Access Journals (DOAJ), Google Scholar, PubMed (NLM), LISTA (EBSCO), and Web of Science have been searched. EVIDENCE SYNTHESIS For clinical use of the MSCs in wound healing, two key issues should be taken into account: First, engineering biocompatible scaffolds clinical use of which leads to the least amount of side effects without any immunologic response and secondly, use of stem cells secretions with the least amount of clinical complications despite their high capability of healing damage. CONCLUSION In light of the MSCs' high capability of proliferation and multilineage differentiation as well as their significant role in modulating immunity, these cells can be used in combination with tissue engineering techniques. Moreover, the MSCs' secretions can be used in cell therapy to heal many types of wounds. The combination of MSCs and PRP aids wound healing which could potentially be used to promote wound healing.
Fluid resuscitation in paediatric burns: how do we get it right? A systematic review of the evidence
Archives of Disease in Childhood. 2018
BACKGROUND Optimal fluid resuscitation in children with major burns is crucial to prevent or minimise burn shock and prevent complications of over-resuscitation. OBJECTIVES To identify studies using endpoints to guide fluid resuscitation in children with burns, review the range of reported endpoint targets and assess whether there is evidence that targeted endpoints impact on outcome. DESIGN Systematic review. METHODS Medline, Embase, Cinahl and the Cochrane Central Register of Controlled Trials databases were searched with no restrictions on study design or date. Search terms combined burns, fluid resuscitation, endpoints, goal-directed therapy and related synonyms. Studies reporting primary data regarding children with burns (<16 years) and targeting fluid resuscitation endpoints were included. Data were extracted using a proforma and the results were narratively reviewed. RESULTS Following screening of 777 unique references, 7 studies fulfilled the inclusion criteria. Four studies were exclusively paediatric. Six studies used urine output (UO) as the primary endpoint. Of these, one set a minimum UO threshold, while the remainder targeted a range from 0.5-1.0 mL/kg/hour to 2-3 mL/kg/hour. No studies compared different UO targets. Heterogeneous study protocols and outcomes precluded comparison between the UO targets. One study targeted invasive haemodynamic variables, but this did not significantly affect patient outcome. CONCLUSIONS Few studies have researched resuscitation endpoints for children with burns. Those that have done so have investigated heterogeneous endpoints and endpoint targets. There is a need for future randomised controlled trials to identify optimal endpoints with which to target fluid resuscitation in children with burns.
Management of bleeding in major burn surgery
Burns : Journal of the International Society for Burn Injuries. 2018
Major burn surgery is often associated with excessive bleeding and massive transfusion, and the development of a coagulopathy during major burn surgery is associated with increased morbidity and mortality. The aim of this study was to review the literature on intraoperative haemostatic resuscitation of burn patients during necrectomy to reveal strategies applied for haemostatic monitoring and resuscitation. We searched PubMed, EMBASE, and CENTRAL for studies published in the period 2006-2017 concerning bleeding issues related to burn surgery i.e. coagulopathy, transfusion requirements and clinical outcomes. In a broad search, a total of 1375 papers were identified. 124 of these fulfilled the inclusion criteria, and six of these were included for review. The literature confirmed that transfusion requirements increases with burn injury severity and that haemostatic monitoring by TEG((R)) (thrombelastography) or ROTEM((R)) (rotational thromboelastometry) significantly decreased intraoperative transfusions and was useful in predicting and goal-directing haemostatic therapy during excision surgery. Resuscitation of bleeding during major burn surgery in many instances was neither standardized nor haemostatic. We suggest that resuscitation should aim for normal haemostasis during the bleeding phase through close haemostatic monitoring and resuscitation. Randomised controlled trials are highly warranted to confirm the benefit of this concept.
Measuring coagulation in burns: an evidence-based systematic review
Scars, Burns & Healing. 3:2059513117728201, 2017 Jan-Dec.. 2017;3:2059513117728201
Introduction: Dynamic monitoring of coagulation is important to predict both haemorrhagic and thrombotic complications and to guide blood product administration. Reducing blood loss and tailoring blood product administration may improve patient outcome and reduce mortality associated with transfusion. The current literature lacks a systematic, critical appraisal of current best evidence on which clinical decisions may be based. Objectives: Establishing the role of different coagulation markers in burn patients, diagnosing coagulopathy, tailoring blood product administration and indicating prognosis. Methods: Literature during 2004-2017 from the Cochrane Library, PubMed, Scopus, Medline and Embase was reviewed. Eligibility criteria included randomised controlled trials, systematic reviews, multi-/single-centre study and meta-analyses. Keywords searched were 'burns', 'blood coagulation disorders', 'rotem', 'blood coagulation' and 'thromboelastography'. The PRISMA flow system was used for stratification and the CASP framework for appraisal of the studies retrieved. Results: In total, 13 articles were included after inclusion/exclusion criteria had been applied to the initial 79 studies retrieved. Hypercoagulation increases in proportion to the severity of thermal injury. Whole blood testing, using thrombelastography (TEG) and rotation thromboelastometry (ROTEM), was superior to standard plasma based tests, including prothrombin time (PT) and activated partial thromboplastin time (APTT) at detecting burn-related coagulopathies. Conclusions: Routine laboratory markers such as PT/APTT are poor indicators of coagulation status in burns patients. Viscoelastic tests, such as TEG and ROTEM, are efficient, fast and have a potential use in the management of burn patients; however, strong evidence is lacking. This review highlights the need for more randomised controlled trials, to guide future practice.
Fluid resuscitation in patients with severe burns: a meta-analysis of randomized controlled trials
Academic Emergency Medicine : Official Journal of the Society for Academic Emergency Medicine. 2017;25((3):):320-329
OBJECTIVES Fluid resuscitation is the mainstay treatment to reconstitute intravascular volume and maintain end-organ perfusion in patients with severe burns. The use of a hyper-osmotic or iso-osmotic solution in fluid resuscitation to manage myocardial depression and increased capillary permeability during burn shock has been debated. We conducted a systematic review and meta-analysis to compare the efficacies of hyper-osmotic and iso-osmotic solutions in restoring hemodynamic stability after burn injuries. METHODS PubMed, Embase, Cochrane Library, Scopus, and ClinicalTrials. gov registry were searched. Randomized control trials evaluating the efficacy and safety of hyper-osmotic and iso-osmotic fluid resuscitation in patients with burn injuries were selected. Eligible trials were abstracted and assessed for the risk of bias by 2 reviewers and results of hemodynamic indicators in the included trials were analyzed. RESULTS Ten trials including 502 participants were published between 1983 and 2013. Compared with iso-osmotic group, the hyper-osmotic group exhibited a significant decrease in the fluid load (vol/%TBSA/weight) at 24 h postinjury, with a mean difference of -0.54 (95% confidence interval = -0.92 to -0.17). No differences were observed in the urine output, creatinine level, and mortality at 24 h postinjury between groups. CONCLUSIONS Hyper-osmotic fluid resuscitation appears to be an attractive choice for severe burns in terms of total body surface area or burn depth. Further investigation is recommended before conclusive recommendation. This article is protected by copyright. All rights reserved.
Albumin administration for fluid resuscitation in burn patients: a systematic review and meta-analysis
Burns : Journal of the International Society for Burn Injuries. 2016;43((1):):17-24
OBJECTIVE The objective was to systematically review the literature summarizing the effect on mortality of albumin compared to non-albumin solutions during the fluid resuscitation phase of burn injured patients. DATA SOURCES We searched MEDLINE, EMBASE and CENTRAL and the content of two leading journals in burn care, Burns and Journal of Burn Care and Research. STUDY SELECTION Two reviewers independently selected randomized controlled trials comparing albumin vs. non-albumin solutions for the acute resuscitation of patients with >20% body surface area involvement. DATA EXTRACTION Reviewers abstracted data independently and assessed methodological quality of the included trials using predefined criteria. DATA SYNTHESIS A random effects model was used to assess mortality. We identified 164 trials of which, 4 trials involving 140 patients met our inclusion criteria. Overall, the methodological quality of the included trials was fair. We did not find a significant benefit of albumin solutions as resuscitation fluid on mortality in burn patients (relative risk (RR) 1.6; 95% confidence interval (CI), 0.63-4.08). Total volume of fluid infusion during the phase of resuscitation was lower in patients receiving albumin containing solution -1.00ml/kg/%TBSA (total body surface area) (95% CI, -1.42 to -0.58). CONCLUSION The pooled estimate demonstrated a neutral effect on mortality in burn patients resuscitated acutely with albumin solutions. Due to limited evidence and uncertainty, an adequately powered, high quality trial could be required to assess the impact of albumin solutions on mortality in burn patients.
Albumin in burn shock resuscitation: a meta-analysis of controlled clinical studies
Journal of Burn Care Research. 2016;37((3):):e268-78
Critical appraisal of outcomes after burn shock resuscitation with albumin has previously been restricted to small relatively old randomized trials, some with high risk of bias. Extensive recent data from nonrandomized studies assessing the use of albumin can potentially reduce bias and add precision. The objective of this meta-analysis was to determine the effect of burn shock resuscitation with albumin on mortality and morbidity in adult patients. Randomized and nonrandomized controlled clinical studies evaluating mortality and morbidity in adult patients receiving albumin for burn shock resuscitation were identified by multiple methods, including computer database searches and examination of journal contents and reference lists. Extracted data were quantitatively combined by random-effects meta-analysis. Four randomized and four nonrandomized studies with 688 total adult patients were included. Treatment effects did not differ significantly between the included randomized and nonrandomized studies. Albumin infusion during the first 24 hours showed no significant overall effect on mortality. However, significant statistical heterogeneity was present, which could be abolished by excluding two studies at high risk of bias. After those exclusions, albumin infusion was associated with reduced mortality. The pooled odds ratio was 0.34 with a 95% confidence interval of 0.19 to 0.58 (P < .001). Albumin administration was also accompanied by decreased occurrence of compartment syndrome (pooled odds ratio, 0.19; 95% confidence interval, 0.07–0.50; P < .001). This meta-analysis suggests that albumin can improve outcomes of burn shock resuscitation. However, the scope and quality of current evidence are limited, and additional trials are needed.
