Background: The hematopoietic growth factor erythropoietin (EPO) attracts attention due to its all-tissue-protective pleiotropic properties. The purpose of this study is to investigate the effect of EPO in experimental burn wounds healing. Methods: Fifteen healthy Sprague-Dawley, strain of Rattus Novergicus weighing 300-350 grams, were prepared to achieve deep dermal burns. Animals were randomized to receive either low-dose EPO injection (600 IU/mL), high-dose EPO injection (3000 IU/mL) or nothing (control group). After 14 days of observations, quantitative and qualitative assessments of wound healing was determined. Results: The size of the wound area and re-epithelialization rate percentage was determined on Day-0, Day-5, Day-10, and Day-14. The average of raw surface areas measurement (p value: 0.012 in day-5; 0.009 in day-10 and 0.000 in day-14) and healing percentage of the lesions (p value: 0.011 in day-5; 0.016 in day-10 and 0.010 in day-14) were significantly best in the low-dose EPO grup compared to the control group and high-dose EPO grup. The histopathology evaluation revealed that the highest score for for re-epithelialization, granulation tissue and neo-angiogenesis were achieved by the low-dose EPO injection group than in both control and high-dose EPO injection groups. Conclusion: In this animal study using Sprague-Dawley rats, Recombinant Human EPO (rHuEPO) injection administration prompted the evidences of improved re-epithelialization and wound healing process of the skin caused by deep dermal burns. These findings may lead to a new therapeutic approach to improve the clinical outcomes for the management of burns wound healing.

Background : Severe burns are among the commonly occurring trauma with lethal outcome. One of the important aspects of severe burn therapy is to quickly achieve wound healing. Previous reports indicated that mesenchymal stem cells (MSCs) therapy contributes in facilitating better wound healing. In this report, we investigated the effects of MSCs derived from human bone marrow and umbilical cord on wound healing in patients with severe burns and its mechanism. Method : We performed human bone marrow and human umbilical cord MSCs therapy on 3 severe burns patients. Two of the patients had inadequate donor to close raw surface with skin graft, whilst one patient had infected chronic burn wound which have failed to epithelialize despite repeated attempts of skin graft and wound care. Result : We observed that MSCs therapy significantly accelerated wound healing. The effects after MSCs migrated into wound were decreased infiltration of inflammatory cells and faster epithelialization. Conclusion : This study suggests that MSCs therapy has positive effects in improving wound healing in severe burns patients. Data provided by this research may serve as theoretical basis for further study of MSCs application in burn wound therapy.

Background : Burns result in severe injuries that cause damage or loss of tissue due to contact with sources of heat resulting in injuries to all body systems. Injuries of the skin, which functions as a barrier to protect internal organs, may cause patients to experience damage to one's physical appearance and body image causing negative feelings that may lead to other problems such as psychopathology and symptoms of mental illness. Method : A cross sectional study with consecutive sampling method of burn patients who were treated at the Plastic Surgery Outpatient Clinic and Burn Unit of RSCM was conducted between April-May 2017. Subjects were asked to fill in self-report questionnaires including patient identity form, SRQ-20 (cutoff point ?6) for presence of psychopathology, and WHOQoL-BREF to obtain mean scores of quality of life that include four domains of physical, psychological, social, and environment assessment. Data collected was analyzed using correlation analysis. Result : 56 burn patients were included in the study. 30.4% did not work and 48.2% had very low income per month. 67.9% patients experienced burns due to fire and 44.6% had burns 10-30% of the TBSA with a majority of patients (80.4%) experiencing a combination of second & third degree burns. Based on the analysis, 57.1% of patients had a form of psychopathology and low mean scores of quality life (physical domain 48.1, psychological domain 51.5). Significant negative correlations (p ? 0.05) were obtained between the psychological domain and symptoms of depression, anxiety, low energy; physical domain and low energy; and social domain with anxiety. Conclusion: This study obtained significant results to identify the correlation between psychopathology and various domains of quality of life affected.

Background: Intense and prolonged pain often caused by burn injuries. The greatest pain is mostly experienced during dressing changes to maintain healing and banish the infection. This review is conducted to assess the effectiveness and safety of different analgesia agents or methods for dressing changes in burn patients. Method: Searches of studies conducted from 4 electronic databases, using keywords “Analgesia”, “Dressing”, “Bandages”, “Changes” and “Burns”. We included randomized and quasi-randomized trials assessing and comparing the effects of different analgesia agents, analgesia methods for dressing changes in burns patients. We excluded trials reporting only pharmacokinetic and physiological outcomes, comparing drug dosages, with exception for those using different drugs in the same class. Result: Multiple databases search retrieved 144 studies. 17 trials are eligible involving 700 patients. Analgesia using pharmacological agents in 7 trials; 5 trials elaborating primary treatments and 2 trials as the adjunct treatment complementing the major analgesia. Two primary analgesia treatments were studying the role of patient-controlled analgesia (PCA), while 3 trials using caregiver delivered. Ten trials were observing the role of non-pharmacological analgesia. Conclusion: There was inadequate evidence from comparisons tested in randomized trials to confirm the dependent effectiveness of various techniques of analgesia, individual methods, or to assess the administration of different drug adjuncts for providing analgesia during dressing changes. Given the unresolved questions about the management of these conditions, we suggest that preference should be focused on the large scale, optionally, multi-center randomized observations of the primary methods.

Background: Burn injury is considered as major problem because of high mortality and morbidity. One of the several managements to decrease the mortality rate is wound excision. This study aimed to describe the characteristics of burn mortality in our burn unit and its association with timing of tangential excision. Method: We collect data of burn patients who died in 2016 at Burn Unit of Cipto Mangunkusumo Hospital. We investigate the association of mortality and timing of tangential excision. The data were compared with other studies from online databases. Result: Thirty-four burn patients died at RSCM Burn Unit from January - December 2016. 13 patients underwent early tangential excision, the rest had delayed or no tangential excision. Only length of stay (LOS) has statistically significant result. The early tangential excision group has significantly longer median LOS (p=0.003) compared to delayed tangential excision. From five relevant studies, three studies had higher mortality in early tangential excision group compared to delay group but fewer complications and shorter LOS. Two studies reported a significant reduction in mortality in early tangential excision group while culture positive wounds were more frequent in the delay group. Conclusion: Mortality in our patients in early tangential excision group is fewer than the delayed one. The early tangential excision group has longer length of stay compared to delay tangential excision. Although there are pros and cons from the literature review, we suggest that early tangential excision should be done in burn patients.

Background : Burn injury has a great impact on mortality and morbidity in children. Significant loss of albumin (hypoalbuminemia) in burn patient often leads to serious complications. However, it is still unclear whether serum albumin has a role in the success of fluid resuscitation in children with burn injury. Method : This is a retrospective cohort study based on medical record of children hospitalized with burn injury at Cipto Mangunkusumo Hospital Burn Centre from January 2012-March 2018. The subjects collected with the total sampling method. Result : Most burn injury happen because of scalds, and have grade 2 burn injury with PELOD score<10. Almost all subjects was succesfully resuscitated in the first 24 hour (95,1%). No association was found between the success of fluid resuscitation with either serum albumin [RR 1,175(95%CI 0,3-4,4) p=0,812], or with ureum, creatinin, lactate level, weight and the degree/extent of the burn injury. Conclusion: The success rate of fluid resuscitation in pediatric burn injury was quite high in Cipto Mangunkusumo Hospital Burn Centre. No association was found between serum albumin and the success of fluid resuscitation during the first 24 hour period. Keywords: albumin, burn, pediatric, resuscitation
