“…One case was reported in 1984, and described a 19-year-old man struck by a 20 kV high-voltage electric shock: the patient died after 4 days due to ventricular arrhythmia. At the time of death, the patient was leukopenic, and at autopsy, a decreased bone marrow cellularity with decreased myelopoiesis was recorded [5]. An animal study by Asko-Seljavaara concluded that burns inhibited bone marrow function in rats [6].…”

“…Tulang merupakan jaringan tubuh yang memiliki konduksi rendah terhadap listrik, hal ini menyebabkan panas yang diterima oleh jaringan tulang lebih tinggi dibandingkan jaringan lainnya (Moenadjat, 2011). Penelitian lain yang juga menjelaskan mengenai kerusakan sumsum tulang pasca luka bakar akibat listrik adalah penelitian yang dilakukan oleh Szabo dan Ver (1984) yang menjelaskan bahwa pada pasien pasca luka bakar akibat listrik terjadi aplasia sumsum tulang. Pemeriksaan sumsum tulang menunjukkan depresi total mielopoiesis.…”

Electrical burns cause high mortality and morbidity and various complications, although the incidence is only 4% of all burns. Joule heating phenomenon occurs in electric burn patients which cause changes in erythrocyte morphology resulting hypercoagulability that contribute to the formation of thrombus. Changes in erythrocyte morphology may cause tissue oxygenation disorders and decrease in erythrocyte count leading to hypoxia. Until now there have been no reports of changes in erythrocyte morphology and reduction in the number of erythrocytes in burn patients due to electricity. This study aims to observe and analyze morphological and erythrocyte count in rats after electrical exposure of 140 V for 17 seconds. This is a true experimental laboratories study with post-test only control group design. The sample used were 24 rats consisting of one control group (K) and five treatment groups (P). Treatment groups were distinguished by days of blood sampling that is days 0 (P1), 3 (P2), 7 (P3), 10 (P4), and 14 (P5) post electrical exposure of 140 V for 17 seconds. Assessment in erythrocyte morphology was performed using giemsa staining that observed with 1000x magnification while erythrocyte count was performed using improved neubauer counting chamber. One Way Anova showed that there was no significant change in rats erythrocyte count after electrical exposure of 140 V for 17 seconds (p = 0.110). Descriptive analysis showed that there is morphological changes in erythrocyte morphology after electrical exposure of 140 V for 17 seconds, in terms of shape there are more fragmentosit, microsite, tear drops, stomatocytes, and cell target, in terms of size there are more microsite, and in terms of color there are more hypochromic erythrocytes.

“…Sometimes prolonged anemia may be encountered in large burns and may persist for more than 2 months after the initial trauma, in spite of considerable amounts of blood units given to the patient. Depression of the bone marrow added to the losses due to surgical procedure and daily debridement of the deep wounds [21], [22], [23].…”

BACKGROUND: Electrical burns, although constituting a small part of the burns treated in a tertiary hospital, remain a constant burden to the medical staff, due to the nature of the causative agent. PATIENTS AND METHODS: After the Institutional Review Board approval, a retrospective study was performed including all the patients admitted to the Service of Burns and Plastic Surgery, University Hospital Center “Mother Theresa” of Tirana, Albania, from January 2018 to December 2019. Descriptive statistics was used to review the cases for age distribution, body surface area burned, points of entry and exit of the current, acute and late complications, surgical approach, and timing of the latter. RESULTS: Twenty-six patients were admitted during this period, of which 22 suffered a real electrical burn, four of them having only superficial damage from the flash of the electric arc without direct contact with the electrical source. Mean hospital stay was 58.1 days for true electrical burns and 7.5 days for burns from electrical arc. Each patient underwent three surgical interventions in average, of which 20% were fasciotomies, 30% were eschar excision, 35% were reconstructive procedures, and 15% were amputations. Only one fatal outcome was registered. About 36% of the patients were children and the only death was registered among them. Most of cases were due to neglect of safety measures while working with the electrical power, although being professional qualified workers. Acute complications were myoglobinuria, cardiac rhythm disorders, respiratory acidosis, psychomotor agitation, brain concussion and contusion, and acute bleeding. Anemia is the most common late complication. CONCLUSIONS: The prevention is still the best treatment, especially for true electrical burns. Working with the corporate that controls the production and transmission of the electrical power could further reduce the incidence of true electrical burns, while moving to more aggressive surgical approach to such burns might avoid long-term complications and degree of invalidity caused by them.
