A study on 161 patients treated in the Burn Department of Chî RÉy Hospital has shown that the accidents occurred frequently in ages of 15-40. The major circumstances of accidents mainly were antenna installation, construction, and house repair under the high change electricity. The electric equipment and machines did not cause the electric burn but severe cardiac lesion. The mortality rate was very high. The active, urgent artificial respiratory and cardiac massage is very important after cutting the electric resource.

Transient hyperkalemia has been reported to occur in eletric burn patients following intravenous administration of succinylcholine. We have studied the origin of the elevated serum K+ concentration after injection of succinylcholine from both the non-burned area and from the burned area in electirc burn patients. Blood samples for serum K+ measurement were drawn 1,2,3,4,5 and 10 minutes after administration of succinylcholine from both the burned are and the non-burned area in 6 electric burn patients. The following results were obtained: 1) Serum K+ levels increased in the burned group in 3 minutes after injection of succinylcholine. 2) The serum K+ concentration of venous samples from the electric burn area were more increased than from the non-burned area injection of succinylcholine.

Objective: To analyze the literature published in Chinese Journal of Burns (now Chinese Journal of Burns and Wounds) in the last 22 years, and to explore the development trend of burn discipline. Methods: The relevant clinical and research literature published in Chinese Journal of Burns from January 1, 2000 to December 31, 2021 were retrieved through China National Knowledge Infrastructure database. Bibliometrics was used to classify and analyze the literature by research types, involved research fields, and reported causes of injury, and compare them every 3 years according to the year of publication (with literature published in 2021 being included in the last time period). Keywords of all the literature were retrieved, which were corrected and conversed later. CiteSpace 6.1.R2 software was used to visually cluster the included keywords, count high-frequency and high-centrality keywords, and divide the high-frequency keywords by time as before for segment comparison. Results: A total of 4 485 relevant papers were included, with an average of about 204 papers each year. The research types analysis of literature showed that clinical diagnosis and treatment literature had the highest proportion, reaching 65.3% (2 929/4 485), followed by cell experiment and animal experiment literature, accounting for 18.1% (812/4 485) and 13.2% (591/4 485), respectively. The proportion of various research types of the literature in each time period was basically stable. The analysis of the research fields involved in the literature showed that the literature in the field of systemic treatment of burns accounted for the highest proportion, reaching 60.2% (2 699/4 485), followed by the literature in the fields of acute wounds and plastic surgery, accounting for 20.2% (908/4 485) and 7.3% (326/4 485), respectively. The proportion of the literature in the field of systemic treatment of burns decreased from 84.0% (430/512) in 2000-2002 to 40.3% (373/926) in 2018-2021, with a decreasing proportion of 43.7%. While compared with that in 2000-2002, the proportions of literature in the fields of acute wounds, plastic surgery, chronic wounds, and burn rehabilitation were on the rise, with the proportions in 2018-2021 increased by 11.7%, 9.1%, 10.7%, and 5.5%, respectively. In the first 6 time periods, the number of literature in the field of discipline management was few and remained in single digits, but it increased to 49 in 2018-2021. Among the 1 099 literature in the field of systemic treatment of burns with a clear cause of injury, the literature on thermal burns was the most, accounting for 58.5% (643/1 099), followed by the literature on electrical burns and chemical burns, accounting for 19.8% (218/1 099) and 12.6% (138/1 099), respectively. The comparison by time period showed that the proportion of literature reporting thermal burns showed a significant downward trend, while the proportion of literature reporting other causes of injury did not change significantly. A total of 6 822 keywords from 2 236 literature were included for analysis. Visual cluster analysis showed that relevant studies focused on burns, surgical flaps, scars, and wound healing. The top 3 keywords in frequency were burns, wound healing, and surgical flaps, and the top 3 keywords in centrality were burns, scars, and skin transplantation. The comparison by time period showed that the only keyword with a stable frequency in the top 10 ranks was burns; with the passage of time, some keywords such as endotoxin/endotoxins and fibroblasts gradually dropped out of the top 10 ranks, while keywords such as wounds and injuries, surgical flaps, and negative-pressure wound therapy gradually entered the top 10 ranks. Conclusions: Among the literature published in Chinese Journal of Burns during the last 22 years, the literature on systemic treatment of burns and thermal burns has gradually decreased, while the literature on chronic wounds and burn rehabilitation has increased. Surgical flaps, wound healing, and scar prevention and treatment are the current research hot spots in burn discipline.

Transient hyperkalemia is well known to occur in man following intravenous administration of succinylcholine chloride. We studied the change of the serum potassium concentration after injection of succinylcholine in nonburn patients and electricburn patients, physical status 1 or 2 adopted by the American Society of Anesthesiologists. We compared two groups: Non-burn patient group(Group 1) as control, Electric burn patient group (Group 2) as experimental. The following results were obtained: 1) In non-burn patient group(Group 1) serum potassium concentration was slightly decreased in the 1st, 2nd, 3rd, 4th, 5th, 6th and 10th minute after succinylcholine injection compared with control, but nostatistical significance was noticed in this group. 2) In electric burn patient group (Group 2) serum potassium concentration was maximally increased compared with the controls. Statistical significance was noticed at the 2nd and 3rd minute after succinylcholine injection in this group.

The electric burn is a kind of special injury, in which the injured areas are not big, but deep tissues and organs are often injured, resulting in higher rates of mortality and amputation than thermal injury. In the process of management, besides the treatment for systemic and pathologic changes, wound repair is also emphasized for restoration of function. In the past 50 years, ten thousand patients with electric burn were cured in our country, including hundreds of severe electric burn patients with extensive injury. Lots of operative regimes for electric burn were developed, and the scope of experimental research was broadening. As a result, six monographs concerning electric burns were published. However, clinical management of severe electric burn to give a satisfactory result is still difficult, therefore further indepth research is necessary, especially in the field of the use of artificial skin, vessels, nerves, muscular tendon, etc. from gene and tissue engineering to improve quality of wound repair.

OBJECTIVETo study the influence of high-voltage electric burn on the microcirculation of heart in rabbit.

METHODSOne-hundred and twenty New Zealand rabbits of clean grade were divided into control group (C) and electric burn group (EB) according to the random number table, with 60 rabbits in each group. Rabbits in EB group were subjected to high-voltage electric burn (the electrical current flow into the left foreleg at the lateral side of proximal end and out from the corresponding site of the right hind leg) with voltage regulator and experimental transformer. Rabbits in C group were sham injured with the same devices without electrification. At 15 minutes before injury, and 5 minutes, 1, 2, 4, 8 hour (s) post injury (PIM or PIH), ten rabbits in each group were chosen to examine the cardiac apex microcirculation hemoperfusion (CAMH) with laser Doppler hemoperfusion image instrument. The morphologic changes of microvessels of left ventricular wall tissues of 2 rabbits from each of the 10 rabbits collected at above-mentioned time points were observed with light microscope and transmission electron microscope. Auricular vein blood of rabbit was harvested at above-mentioned time points for the determination of aspartate amino transferase (AST), lactate dehydrogenase (LDH), hydroxybutyrate dehydrogenase (HBDH), creatine kinase (CK), and creatine kinase isozyme MB (CK-MB) by full-automatic biochemical analyzer. Data were processed with two-factor analysis of variance and LSD test.

RESULTS(1) The differences between C group and EB group in detection results were statistically significant, with F values from 425.991 to 3046.834, P values all below 0.01. Only the data within EB group were comparable. (2) At PIM 5, the CAMH value of rabbits in EB group was (1.96 ± 0.09) V, which was lower than that at 15 minutes before injury [(4.34 ± 0.35) V, P < 0.01]. The CAMH value of rabbits in EB group was increased at PIH 1 [(3.43 ± 0.30) V], and then it showed a tendency of decrease. (3) Bleeding and microthrombus formation were observed in venule and capillary vessel of rabbits in EB group at PIH 8. Breakage of basement membrane of capillary endothelial cells, mitochondrial swelling, and severe degranulation from damaged endoplasmic reticulum were observed in rabbits of EB group at PIH 8. (4) Levels of AST, LDH, HBDH, CK, and CK-MB in rabbits of EB group were significantly higher at PIH 1, 2, 4, 8 than at 15 minutes before injury (with P values all below 0.01). The AST level peaked at PIH 2 [(164 ± 39) U/L]. Levels of LDH and HBDH peaked at PIH 4, which were respectively (1016 ± 246) U/L and (487 ± 54) U/L. The CK level peaked at PIH 8 [(7799 ± 738) U/L]. The CK-MB level peaked at PIH 2 [(1848 ± 65) U/L].

CONCLUSIONSHigh-voltage electric burn can bring damage to the microvessels of heart in rabbits and change blood flow of microcirculation, which should be given adequate attention during the treatment.

To evaluate the various factors related to the development of electric cataract in electric burn patients, we reviewed medical charts of 663 electric burn patients who were admitted to the department of General Surgery in Hanil General Hospital between 1981 and 1993. Eleven patients(1.7%) had electric cataract in both eyes. All of them were injured by contact with 22,900 voltage current, and developed third degree burns. Fifty-eight electric burn patients had their electric inputs through their head and eight (13.8%) among them developed cataracts. Only three(0.5%) among 567 electric burn patients who had their electric inputs through upper extremities developed cataracts. The interval between the electric injury and the diagnosis was 2 to 18 months. Anterior subcapsular opacity was the most common type of lenticular opacity. Other associated ocular complications included uveitis, macular edema, macular degeneration, and macular hole.

BACKGROUND: Occupational accidents are unplanned events that cause damage. The socio-economic impacts and human costs of accidents are tremendous around the world. Many fatalities happen every year in workplaces such as electricity distribution companies. Some electrical injuries are electrocution, electric shock, and burns. This study was conducted in an electricity distribution company (with rotational 12-hour shift work) in Iran during an 8-year period to survey descriptive factors of injuries. METHODS: Variables collected included accident time, age of injured worker, employment type, work experience, injury cause, educational background, and other information about accidents. RESULTS: Results indicated that most of the accidents occurred in summer, and 51.3% were during shift work. Worker negligence (malpractice) was the cause of 75% of deaths. Type of employment had a significant relationship with type of injuries (p < 0.05). Most injuries were electrical burns. CONCLUSION: High rate of accidents in summer may be due to the warm weather or insufficient professional skills in seasonal workers. Shift workers are at risk of sleep complaints leading to a high rate of work injuries. Acquiring knowledge about safety was related to job experiences. Temporary workers have no chance to work all year like permanent workers, therefore impressive experiences may be less in them. Because the lack of protective equipment and negligence are main causes of accidents, periodical inspections in workshops are necessary.

PURPOSE: A vast array of injuries result from high voltage electrical damage. The compartment syndrome of forearm prone to have high risk of major amputations, especially in arc burn. Early decompressing fasciotomy has been recommended for the prevention of limb amputations. There are controversies about the effect of fasciotomy. We tried to Pressure Cuff Recording (PCR) wave forms of Plethysmography for the monitoring early signs of vascular compromises in decision of early selective fasciotomy. We investigated the role of PCR wave forms to reduce major amputation rate. METHODS: We reviewed 875 burned limb of 520 electric current damage victims (fasciotomy or amputation were performed, PCR wave forms evaluated) during the last 14 years (from Jan. 1, 1996 to Jun. 30, 2009). We analysed the differences of amputation rates by the currency, input/output, burn types, effects of PGE1 adminstration, fasciotomy time, converting of PCR wave forms. RESULTS: There was no major amputations among low tension victims (minor amputation rate; 0.3%). The minor and major amputation rate were 19.5% and 27.0 in high tension injury. The flash burns rarely made the amputations, but arc burns had 12.1% of minor and 41.2% of major amputations. The direct contact burns had 24.7% of minor and 21.3% of major amputations. Most of the victims had their hand as input and foot as output. The minor and major amputation rate were 26.2% and 10.9% in none-fasciotomy, 8.8% and 48.0% in within 8 hours, 10.0% and 52.9% in 8-24 hours, 9.3% and 63.0% in over 24 hours fasciotomy group. Final normal type (N type) of PCR result had only 3.1% of minor amputations and 3.1% of major amputations. Final obstructive type (O type) had 37.6% of minor amputations, 60.8% of major amputations. Initial stenotic type (S type) of converted to N type had 6.6% amputation, but to O type had 98.7% amputation. CONCLUSION: The early selective fasciotomy are essential to reduce major amputations in high tension injuries, especially in arc burns. The PCR wave form converting to obstructive type could be helpful to predict the possible amputation. The PCR wave form is a good tool to monitor early signs of vascular compromise around fasciotomy. It plays as the index of immediate fasciotomy decision.

PURPOSE: Prealbumin is known as a biochemical marker for assessing nutritional status, and it is influenced by a systemic inflammatory condition. This study aims to find any correlation between patients' low serum prealbumin in electrical burn and unhealed burn surface area and insufficient nutritional support. METHODS: Data were collected by a review of the medical charts of patients admitted to Hanil General Hospital for electrical burn. Laboratory results such as prealbumin, albumin, total lymphocyte count (TLC), and C-reactive protein (CRP) were collected and tested every week. Residual burn surface area (residual BSA) during a specific period was calculated from the surgery record. Statistical analysis was conducted using Pearson's correlation and multiple regression analysis. RESULTS: A total of 30 subjects were selected, all male. Average total burn surface area was 20.9±14.9%, and patients were operated on about three times after admission. There was statistical significance among all variables in Pearson's correlation test, but in multiple regression analysis, albumin and CRP were significant compared with prealbumin. CONCLUSION: The results could indicate that burn causes a systemic inflammatory reaction, which could affect the serum prealbumin level. Further study concerning the biological plausibility of each variable is needed.
