Extracorporeal Life Support Use in Mixed Distributive-Obstructive Shock Following an Electrical Injury: A Case Report.

Electrical burn injuries can be catastrophic, threatening severe disability or mortality. We present a patient who suffered from electrical shock, requiring bilateral above-knee amputations, right trans-radial amputation, renal replacement therapy, and veno-arterial extracorporeal life support (VA ECLS) therapy. While there exist reports of cases that have demonstrated the potential use of ECLS in burn patients with cardiogenic shock or acute respiratory distress syndrome, this is a unique case of VA ECLS use for an electrical injury patient who developed mixed distributive-obstructive shock secondary to pulmonary embolism and sepsis. Given the wide variety of morbidities that can result from electrical burns, VA ECLS is a promising tool for those who require cardiopulmonary support refractory to traditional measures.

The cost of keeping warm: a relationship between a rise in the cost of domestic energy and burn injuries caused by personal heating equipment.

INTRODUCTION: During 2022-2023, the UK found itself in the midst of a domestic energy crisis, with the average domestic gas and electricity bill rising by 75% between 2019 and 2022. As a result, the use of hot water bottles, radiant heaters, and electric blankets increased. An unintended consequence of this may be an increase in burn injuries caused by misfortune, misuse, or the use of items in a state of disrepair. PURPOSE: The aim of this study was to explore any increase in referrals to a single burns centre in England for injuries caused by hot water bottles, radiant heaters, or electric blankets. METHODS: This was a retrospective study of a prospectively maintained database of referrals. All referrals between January 2022 and January 2023 were selected and compared with the same period from 2020-2021 (before the rise in energy prices). Referrals were screened for the terms "hot water bottle," "electric heater," "electric blanket," and "heater." Total referrals in each period, demographic data (age, gender), anatomical location and the mechanism of injury were compared between cohorts. RESULTS: We found a statistically significant increase in the number of burns relating to heating implements between 2020/21 and 2022/23, rising from 54 to 81 (p = 0.03) - a 50% increase in injuries. Injuries in working age adults increased significantly (52% to 69%, p < 0.05). The most frequently injured area was the leg (30%) followed by the hand (18%). The commonest type of injury described was scald (72%). We found a moderately-strong correlation between the number of referrals and the average cost of energy in 2022-23. CONCLUSION: The number of injuries sustained by people using personal heating equipment is significantly increasing, which correlated with the rise in domestic energy prices. The most affected demographic appears to be working age adults, with wider implications around lost work-time yet to be explored. Further prospective, population-based work is indicated to assess the strength of the correlation seen in this study.

A Consequence of an Electrical-Burn Injury: Atrial Fibrillation.

Cardiac arrhythmias following electrocution injuries can accompany high-voltage or high- intensity currents. Contributing factors to electrical hazard are the type of current, voltage, resistance, and duration of contact and pathway through the body. It is important to monitor for delayed arrhythmias in patients with an electrical injury. We describe a case of a 52-year-old man who presented after an electrical shock injury while grabbing a 5,000-voltage wire at work. In this case report, we discuss the presentation, management, and follow-up recommendations for this type of injury.

Evaluation of skull bone viability and effect of early surgical intervention in electrical contact burns using 18 F-Sodium Fluoride PET-CT imaging.

OBJECTIVE: Electrical contact burns of the scalp cause serious morbidity and mortality. Early necrotic bone debridement and flap cover are crucial for successful wound closure. 18 F Sodium Fluoride (NaF), with high bone-to-soft tissue activity ratio, is useful for bone viability assessment. This study evaluated the role of 18 F NaF PET-computed tomography (CT) in objectively defining the extent and depth of nonviable calvarial bone, to guide adequate bone debridement. METHOD: Of 20 patients referred to our institute with electrical contact burns of the scalp during a 2-year period, 15 were enrolled in the study. Two weeks after the initial management, tracer uptake pattern was noted on 18 F NaF PET-CT of the head and exposed bone measured. Surgical bone debridement was based on scan findings, followed by wound closure. All patients underwent clinical evaluation and follow-up scan 3 months after surgery. RESULTS: Eight patients showed a central photopenic area in the exposed bone (maximum standardized uptake value [SUVmax] of 0.76 ± 0.14 with mean maximum dimensions 4.10 ± 1.76/2.67 ± 1.54 cm). High tracer uptake (SUVmax, 9.66 ± 6.03) was seen peripheral to the exposed bone (mean maximum dimensions, 8.14 ± 3.03/4.75 ± 1.61 cm). Postoperatively, there was no significant change in tracer uptake in the central debrided region or peri-debridement bone area under the flap. Clinically all patients showed a well-healed flap. CONCLUSION: 18 F NaF PET-CT appears useful for objective evaluation of skull bone viability and planning necrotic bone debridement in patients with electrical contact burns. However, additional studies with longer patient follow-up are required to validate these results.

Electrical injuries in children-a 6-year retrospective study.

BACKGROUND: This study aimed to assess the clinical epidemiological characteristics of children with electrical injuries and discuss the countermeasures for the prevention of electrical injuries in children. METHODS: The children with electrical injuries were grouped according to whether or not they were admitted to the hospital for treatment into inpatient and outpatient groups. Clinical data such as gender, causes of injury and injury-causing voltage distribution in different age groups were analyzed. The factors affecting hospitalization were subjected to χ2 test, Kruskal-Wallis H test, and logistic regression analysis. RESULTS: A total of 321 children were included with 37 divided into inpatient group and 284 divided into outpatient group. The incidence of electrical injuries was highest in children ≤6 years old and in the summer. There were significantly different in gender, place of occurrence, cause of injury and injury-causing voltage between the two groups (p < 0.05). Injury-causing voltage is an independent risk factor affecting hospitalization of children with electrical injuries (OR = 0.116, 95 %CI = 0.040-0.334, p = 0.000). In children ≤6 years old, boys suffered electrical injuries more frequently than girls; battery powered vehicle (47.53 %) was primarily the cause of injury; most of the patients (64.64 %) were exposed to low voltage below 100 Vs, mainly in the case of adolescent children. CONCLUSION: Male preschoolers accounted for the majority of electrical injury cases, and these accidents mostly happened in household electrical appliances and household battery cars. Overall, it is necessary to improve family electrical safety education and reinforce protective measures against electric injury to children.

An increase in electrical burns during the covid lockdown in Western Cape, South Africa.

BACKGROUND: A severe Covid lockdown in South Africa may have changed burn patterns due to the downturn of the economy and stay-at-home policies. We describe the volume and type of burn admitted to a tertiary hospital before and during the Covid lockdown. MATERIALS AND METHODS: This was a retrospective study from before (April 2019-March 2020) and during (April 2020-March 2021) the Covid pandemic. Patient demographics, burn etiology, and clinical outcomes were described. Logistic regression was used to model associations between burn etiology and the Covid period. RESULTS: Of 544 burns, 254 (46.7%) occurred before and 290 (53.3%, p = 0.051) during Covid. The proportion of electrical burns doubled during Covid n = 20, 32.3% vs n = 42, 67.7%, (p = 0.053) periods. At least half were associated with suspected cable or copper theft. On multivariate analysis, flame burns (OR=2.42, p < 0.001), electrical burns (OR=4.88, p < 0.001), and paying patients (OR=4.21, p < 0.001) were more likely to be associated with the Covid period. CONCLUSION: Electrical burns doubled during Covid, potentially related to an increase in cable and copper wire theft, a phenomenon described during hard economic times in other settings. More studies to understand this potential relationship are indicated to prepare burn centers during future pandemics and/or economic hardship.

Characteristics and risk factors for electrical burn injuries: a study based on World Health Organization Global Burn Registry.

OBJECTIVE: Electrical burn injuries (EBIs) represent an important subset of burn injuries, but the information on them from the global level is limited. We aimed to investigate the characteristics and risk factors for EBIs reported to the World Health Organization Global Burn Registry. METHODS: Patients with EBIs and non-EBIs were identified from the registry. Patient demographics, income of the country, setting of the injury occurred, and outcomes were described and compared. Multivariable analysis was performed to identify risk factors associated with the EBIs and their outcomes. RESULTS: Of the 9276 patients, 814 (8.8%) were grouped as EBIs. EBIs patients had a median age of 28 years, and they were predominantly males (89.2%). EBIs were more likely to occur in lower-middle- and low-income countries (60.9% versus 43.4%) and in an occupational setting (49.1% versus 6.7%) than the non-EBIs. Older age, male, lower-income, and occupational and public setting were risk factors for EBIs. For EBIs patients, adolescents and young adults, those from low-middle and low-income countries, and those injured by high-voltage electricity were more likely to have more than 15% of the total body surface area. In addition, those from low-middle and low-income countries and those injured by high-voltage electricity were more likely to die. CONCLUSION: The characteristics of EBIs are significantly different from that of non-EBIs. To prevent EBIs and avoid unpleasant outcomes, particular attention should be given to adolescent boys and young adult men who are employed in electrical jobs in lower-income countries.

[A case of repairing the destructive high-voltage electric burn wounds in the head, face, and neck based on the economic theory of flaps].

In September 8th, 2021, a male patient (aged 18 years) with severe destructive injuries of high-voltage electric burns in the head, face, and neck was admitted to General Hospital of Taiyuan Iron Steel (Group) Co., Ltd. Based on the economic theory of flaps, the flap donor site and transplantation method were optimized and evaluated before surgery, and then debridement of head, face, and neck wounds+removal of necrotic skull+free transplantation of super large latissimus dorsi myocutaneous flap+thin intermediate thickness skin graft transplantation from the left thigh was performed. The extra large flap donor site wound was sutured directly. This surgery reduced the adverse consequences of the flap donor site on the premise of ensure of repair effect. After operation, the patient's condition was stable, the flap and skin graft survived well, the repair effect of wound was well, the scar in the flap donor area was relatively mild, and the upper limb had no dysfunction.

Knowledge, Attitudes, and Practices Regarding Electrical Burns.

Burn prevention programs can effectively reduce morbidity and mortality rates. In this article, we present the findings of our investigation of the knowledge, attitudes, and practices of the Saudi Arabian population regarding electrical burns. Our study was a cross-sectional online survey that used a five-part questionnaire to assess the participant's demographic information, knowledge of electrical burns, attitudes toward electrical injuries, and practices related to electrical burns and their prevention. Overall, 2314 individuals responded to the survey (males: 41.2%; females: 58.8%). A total of 839 participants (36%) had a personal or family history of electrical burns. Approximately ≥90% of the responses to questions on electrical burn-related knowledge were correct; relatively less responses to questions on the extent of tissue damage from electrical burns and arcs were correct (74% and 29%, respectively). Only 54% of the respondents knew that applying first aid to the burn-affected areas at home could lead to a better outcome; 27% and 19% did not know the correct answer and thought that this would not lead to a better outcome, respectively. The most common source of information was school or college (38.9%), followed by social media (20.8%) and internet websites (16.3%). Enhancing community awareness and practices related to electrical burns is a cost-effective and straightforward strategy to prevent the morbidity and mortality associated with electrical injuries.

Temporal Fascia Free Flap for Thumb Coverage in Electrical Burn Injuries: A Case Series Analysis With DASH Score Outcomes Evaluation.

Electrical burns pose unique challenges in reconstructive surgery due to the extensive tissue damage they cause. The thumb is particularly susceptible to electrical burns, leading to severe functional impairment. This case series introduces the use of the temporal fascia free flap for thumb coverage in patients with electrical burn injuries. The study aims to assess the functional outcomes of this approach using the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Six male patients underwent thumb reconstruction using temporal fascia free flaps following electrical burn injuries. The extent of the injury was assessed, and necrotic tissue was debrided. Functional outcomes were evaluated using the DASH questionnaire 6 months postoperation. All procedures were conducted in accordance with ethical guidelines, and informed consent was obtained from all patients. All patients achieved successful transplants using temporal fascia free flaps. The average DASH score at the 6-month follow-up indicated satisfactory functional recovery. Patients reported improvements in thumb mobility and functionality, and the cosmetic appearance of the thumb was acceptable. The appearance of the scar in the donor area was well-received. The temporal fascia free flap proved to be an effective method for thumb reconstruction following electrical burn injuries. Its thin and flexible nature allows for optimal contouring and improved range of motion. Although one case of partial flap loss was observed, overall functional and aesthetic outcomes were satisfactory. Further research with larger sample sizes is warranted to optimize surgical techniques and postoperative care for better outcomes.

Suspected Burn From a 9-Voltage Battery.

Advancements in technology allow for the utilization of low-voltage battery-powered devices for patients admitted to the hospital. There have been rare cases of burns due to leakage of the internal contents from low-voltage batteries, but to date, there have been no reports of electrical burns caused by low-voltage batteries. We present the case of an 89-year-old female who presented to the general surgery service with a suspected electrical burn from laying on a 9-volt battery. The patient underwent operative debridement with no evidence of a deeper injury. The patient continues to follow up with an outpatient wound clinic and is healing well. This case highlights the importance of teaching and raising awareness of all small devices that may become entangled or lost in patients' linens, such as 9-volt telemetry batteries, to prevent harm.

Reconstruction of finger contracture with an expanded first dorsal metacarpal artery perforator flap: A case report.

Volar finger contractures can be challenging for plastic surgeons. The dorsal metacarpal artery perforator (DMCAP) flap is frequently used to cover bones, tendons, and neurovascular structures in the dorsum of the hand after trauma and burns as an alternative to grafts and free flaps. We aimed to report volar finger defect reconstruction with expanded DMCAP flap. A 9-year-old male patient applied to our clinic with the complaint of inability to open the second finger of the left hand after an electrical burn that caused proximal and distal interphalangeal joints flexion contractures. Reconstruction was planned for the patient with a two-session expanded first DMCAP flap. A 16 mL 5 × 3 cm tissue expander was placed in the prepared area from the vertical incision in the first session. The tissue expander was inflated with 4 mL of isotonic solution. The DMCA area was enlarged 6 weeks later by giving 22 mL of isotonic solution. After the pedicle dissection, the 9 × 3 cm DMCAP flap was elevated by dissection over the paratenon. With 180° of rotation, the left-hand second finger was adapted to the 6 × 2 cm defect area on the volar face. The flap donor site was closed primarily. The operation was terminated by placing the hand on a protective splint. There were no complications in the flap in the postoperative 6 months. The patient was referred to the physical therapy and rehabilitation department. As a result, an expanded DMCAP flap may cover volar tissue defects up to the distal phalanx. This report may present the first case in which volar finger contracture reconstruction was performed with an expanded first DMCAP flap after an electrical burn in a pediatric patient.

Severe High-Voltage Electrical Injury: A Rare Case Report.

High-voltage electrical injury usually causes severe tissue damage and serious secondary complications. We report a case of treatment of severe high-voltage electrical injury. A series of personalized and effective treatment plans were created through repeated discussions, we successfully handled a series of acute and critical conditions, including severe limb damage, a very large area of full-thickness abdominal wall defect, abdominal viscera (stomach and liver) necrosis, abdominal infection, renal insufficiency, myocardial damage, and malignant arrhythmia (atrial fibrillation). Finally, the wounds were all closed, the functions of the abdominal organs were restored, and the course of the disease was successfully transitioned into the rehabilitation stage. It took a lot of twists and turns but ultimately saved the patient's life. The successful treatment of this patient provides an important reference for similar patients with serious electrical injury in the future.

[Effects of artificial dermis combined with autologous skin in repairing the wounds with exposed bone and/or tendon in fingers of children after electric burns].

Objective: To explore the effects of artificial dermis combined with autologous skin in repairing the wounds with exposed bone and/or tendon in fingers of children after electric burns. Methods: A retrospective observational study was conducted. From January 2017 to December 2022, 14 children with bone and/or tendon exposed wounds in fingers after electric burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 9 males and 5 females, aged 2 to 11 years. A total of 38 fingers were affected, with 1 wound per finger. After debridement, artificial dermal coverage combined with vacuum sealing drainage was performed in all the wounds in the first stage, with wound area of 2.0 cm×1.0 cm-4.5 cm×2.5 cm after debridement. The second stage surgery was performed to close the wound with autologous thin intermediate thickness skin graft. Then the children were told to perform functional rehabilitation exercise as early as possible. The survival of autologous skin graft was observed at the 7th day after the second stage surgery. The wound healing time was recorded. After 12 months of follow-up, the Vancouver scar scale was used to evaluate the scar hyperplasia at the skin grafting site of the affected finger; the total action mobility (TAM) of the affected finger joint was measured for evaluating the functional recovery of the affected finger; a self-made efficacy satisfaction rating table was used to investigate the parents' satisfaction with the curative effect of the children. Results: At the 7th day after the second stage surgery, all the children had good survival of autologous skin grafts. The wound healing time was (24.1±2.7) d. After 12 months of follow-up, the scar score at the skin grafting site of the affected finger was 5.2±2.4; the TAM of the affected finger joint was (177±40)°; the functional assessment was good in 12 fingers, medium in 23 fingers, and poor in 3 fingers; the parents' satisfaction with the curative effect of the children in the survey was very satisfied in 10 cases, satisfied in 3 cases, and dissatisfied in 1 case. Conclusions: The combination of artificial dermis and autologous thin intermediate thickness skin graft is an alternative surgical method that can effectively repair the bone and/or tendon exposed wounds in fingers of children after electric burns. After wound healing, the scars are slight, the finger function is well recovered, and the parents of the children are highly satisfied with the curative effect of the children, which is worthy of clinical promotion.

[Selection strategy of pedicled axial flaps for repairing high-voltage electric burn wounds in foot and ankle].

Objective: To explore the selection strategy of pedicled axial flaps for repairing high-voltage electric burn wounds in foot and ankle. Methods: The retrospective observational research method was used. From January 2017 to December 2022, 16 patients with skin and soft tissue defects in foot and ankle after high-voltage electric burns were treated in General Hospital of Eastern Theater Command, including 11 cases of unilateral defect and 5 cases of bilateral defect. All patients were male, aged from 25 to 75 years. After thorough debridement, the area of the defect to be repaired with the flap was 5.0 cm×4.0 cm to 12.0 cm×8.0 cm. Before operation, the color Doppler ultrasound, computed tomography angiography, or digital subtraction angiography was used to fully evaluate the degree of vascular injury in the affected limb and to identify the distribution and traffic anastomosis of vascular network. Pedicled axial flaps with reliable blood supply were used to repair the wounds as soon as possible, and the area of flaps ranged from 3.0 cm×2.0 cm to 13.0 cm×8.0 cm. The wound in the donor area of flaps was repaired with split-thickness skin graft from head or medium-thickness skin graft from thigh. The flap repair of wounds in various areas of the ankle and foot was recorded. The postoperative survivals of the flaps and skin grafts were observed after surgery. The postoperative appearance of flaps and walking function of patients were followed up. At the last follow-up, the foot and ankle function was evaluated and rated using the American Association of Foot and Ankle Surgeons Ankle Posterior Foot Scoring System. Results: Two wounds in toe area were repaired with reverse dorsal pedis flaps, 3 wounds in medial ankle area and 2 wounds in heel area were repaired with medial plantar flaps, 2 wounds in anterior plantar area combined with toe area were repaired with reverse medial plantar flaps, 2 wounds in anterior plantar area combined with toe area and 5 wounds in anterior plantar area were repaired with reverse medial pedis flaps, 1 wound in toe area was combined with proper plantar digital artery flap, 1 dorsal pedis wound and 1 lateral malleolus wound were repaired with lateral supramalleolar perforator flaps, and 1 lateral malleolus wound and 1 dorsal pedis wound were repaired with sural neurovascular flap. One flap had venous reflux disorder after surgery and survived after treatment, while the other flaps and skin grafts survived completely after surgery. During the follow-up of 6 to 24 months after operation, the appearance of the flaps was good, and the walking function of patients was normal. At the last follow-up, the functional score of foot and ankle was 76 to 95, which was evaluated as excellent in 11 cases and good in 5 cases. Conclusions: According to the condition of high-voltage electric burn in foot and ankle, early and thorough debridement, preoperative imaging examination to evaluate blood vessels of the affected limb, and selection of pedicled axial flap with reliable blood supply are good methods for wound repair and related functional reconstruction of high-voltage electric burn in foot and ankle.

[Effects of low position lateral supramalleolar flap carrying periosteum and proximal leg propeller flap in relay repair of electric burn wounds of forefoot].

Objective: To explore the effects of low position lateral supramalleolar flap carrying periosteum and proximal leg propeller flap in relay repair of electric burn wounds of forefoot. Methods: A retrospective observational study was conducted. From January 2019 to January 2022, 12 patients with electric burn wounds of forefoot meeting the inclusion criteria were admitted to the Sixth Hospital of Shanxi Medical University, including 10 males and 2 females, aged 23-65 years. After debridement, the wound with an area of 6.0 cm×3.0 cm to 15.0 cm×7.0 cm was repaired with the lateral supramalleolar flap carrying part of the periosteum of the distal tibia and fibula with the rotation point moved down to the front of the ankle joint. The area of the cutted flap was 6.5 cm×3.5 cm-15.5 cm×7.5 cm. At the same stage, the donor site wound of lateral supramalleolar flap was repaired with peroneal artery or superficial peroneal artery perforator propeller flap in relay, with the relay flap area of 3.0 cm×1.5 cm-15.0 cm×4.0 cm. After operation, the survival of the lateral supramalleolar flap and relay flap, and the wound healing of the relay flap donor site were observed. During follow-up, the shapes of the lateral supramalleolar flap and its donor site were observed. Results: After operation, one patient developed secondary blisters in the superficial skin distal to the lateral supramalleolar flap, which healed after dressing change, and the lateral supramalleolar flap and relay flaps survived well in the other patients; the donor site wound of the relay flap healed well. During follow-up of 12-18 months, the lateral supramalleolar flaps were in good shape and not bloated, with only linear scar left in the donor site of the flap. Conclusions: The low position lateral supramalleolar flap carrying periosteum can repair electric burn wounds of forefoot with advantages including reliable blood supply, low rotation point, and better repair effects. The use of relay flap to repair the donor site of lateral supramalleolar flap can reduce the damage to the appearance and function of the donor site.

[Visual analysis of the current research status and hotspots of electric burns at home and abroad].

Objective: To analyze the literature on electric burns published at home and abroad, and to explore the research hotspots and frontiers of electric burns. Methods: The bibliometric method was used. The Chinese and English literature related to electric burns published in China National Knowledge Infrastructure, Wanfang database, VIP database and the core collection of Web of Science database from January 1, 2013 to December 31, 2022 were searched respectively, and the CiteSpace 6.2.R2 software was used for analysis. The number of papers, authors, countries, and institutions of Chinese and English literature were counted respectively, and the co-occurrence analysis of keywords and mutation analysis and cluster analysis on the basis of the co-occurrence analysis were conducted, besides, the clustering time line figure was obtained after the keywords were sorted by time to explore the current research status and the evolution process of hotspots in the field of electric burns. Results: A total of 398 English papers were retrieved from the core collection of Web of Science database, and a total of 523 Chinese papers were retrieved from China National Knowledge Infrastructure, Wanfang database, and VIP database after duplicate check. From 2013 to 2022, the number of English literature published in the field of electric burns showed a steadily upward trend, and the number of published Chinese literature showed a downward trend and tended to be stable. In Chinese literature, a total of 302 authors as the first author published papers related to electric burns, with 17 core authors published ≥3 papers; in English literature, a total of 320 authors as the first author published papers related to electric burns. Researches on electric burns were carried out in 65 countries, with United States having the most cooperation with other countries and the largest number of papers published. A total of 512 institutions at home and abroad published papers related to electric burns, and the institutions with the largest number of Chinese and English papers were Shanghai Electric Power Hospital in China (n=14) and Hallym University in Korea (n=11), respectively. A total of 1 176 Chinese keywords and 1 068 English keywords were included for co-occurrence analysis after excluding keywords related to the searching words. The top three keywords in frequency in Chinese literature were surgical flap, wound repair, and nursing, and the top three keywords in frequency in English literature were management, epidemiology, and children. Ten clusters were obtained by keyword analysis in Chinese literature, and the largest cluster was wound healing, followed by clinical effects and surgical flaps. Seven clusters were obtained by keyword analysis in English literature, and the largest cluster was reconstructive surgical procedures, followed by chronic pain and shock. The persistent clusters in Chinese literature were wound healing and clinical outcomes, etc., and the prominent nodes in the recent two years were surgical timing, limb electric burns, and hypertrophic scars; the persistent clusters in English literature were reconstructive surgical procedures and chronic pain, etc., and the prominent nodes in the recent two years were predictors and burn management, etc. In Chinese literature, the keyword with the longest duration of mutation (2017-2021) was wrist electric burns, and the keyword with the highest intensity of mutation was flap repair; in English literature, the keyword with the longest duration of the mutation (2019-2022) was voltage, and the keyword with the highest intensity of mutation was prevention. Conclusions: There are similarities and differences in the research directions and hotspots of electric burns at home and abroad. Surgical flap repair is a common research hotspot at home and abroad. At present, domestic research focuses on wound healing, wrist electric burns, and other aspects, while international research focuses on treatment management, epidemiology, reconstruction, and other aspects.

[Pay more attention to the management of burn wounds of special causes and sites].

The treatment of burn wounds of special causes and sites is a very challenging clinical work. In this paper, we briefly discussed the incidence rates of chemical burns, electric burns, facial burns, hand burns, and perineal burns, as well as the complexity and severity of pathological injury of the corresponding wound tissue. In addition, we briefly discussed the main principles and methods of clinical treatment, as well as the difficult problems to be solved. It is hoped to attract attention and provide reference for further improving the overall treatment ability of burns.
