Background: High-voltage injuries pose severe risks, particularly among train surfers and occupational workers. This study compares current flow mechanisms and their association with cardiac failure and kidney function problems in these groups. Methods: A retrospective analysis of 102 patients treated for high-voltage injuries between 1994 and 2024 was conducted, including 32 train-surfing and 70 work-related cases. Demographics, current flow patterns, and complications were analyzed. Results: Train surfers, mostly young males (median age: 19 years), sustained more severe burns compared to older males with work-related injuries (median age: 34 years), with a %TBSA of 47.6% vs. 25.4% (p < 0.0001). Vertical electrical flow was predominant among train surfers (65.62%) and led to cardiac failure in 37.5% of cases. In contrast, diagonal flow was most common in work-related injuries (58.57%). Cardiac failure occurred in 21.57% of all patients, with vertical flow posing the highest risk (38.46%). Kidney failure affected 43.75% of train surfers and 21.43% of work-related cases, with dialysis required in 21.57% overall. Train surfers were more likely to require resuscitation (43.75% vs. 15.71%, p = 0.005), while ECG findings showed no significant differences (p = 0.325). Biomarker levels, such as CK, myoglobin, and troponin, were significantly higher in train surfers, reflecting greater muscle damage. Conclusions: Current flow mechanisms significantly influence cardiac and renal complications. Vertical flow, common in train surfers, is strongly associated with cardiac failure, while work-related injuries exhibit varied flow patterns. These findings highlight the need for targeted prevention strategies and public awareness.

Background: High-voltage injuries associated with train surfing are a distinct subset of electrical injuries, yet detailed analyses remain limited. This study retrospectively reviewed train-surfing injuries admitted between 1994 and 2024, comparing their characteristics and outcomes to work-related high-voltage injuries. Methods: Medical records of 102 patients admitted for high-voltage injuries were analyzed, including 32 train-surfing and 70 work-related cases. Demographics, injury patterns, and clinical outcomes were assessed. Results: Train surfers were predominantly young males (median age 19 years), while work-related injuries involved slightly older males (median age 34 years). Train surfers sustained more severe burns (%TBSA: 47.6% vs. 25.4%, p < 0.0001) and higher ABSI scores (6.7 vs. 5.3, p < 0.01). Vertical electrical flow was predominant in train surfing (65.6%), reflecting contact with overhead lines, while work-related injuries showed varied flow patterns, with diagonal flow being most frequent (58.6%). Train surfers had longer ICU stays (38.7 vs. 17.9 days, p < 0.001) and underwent more surgeries per patient (5.3 vs. 2.8, p < 0.01). Fasciotomy rates were significantly higher among train surfers (84.4% vs. 55.7%, p < 0.01), as were amputations (53.1% vs. 25.7%, p < 0.001). Mortality rates were similar in both groups (25%). Conclusions: Train-surfing injuries represent a distinct and highly severe subgroup of high-voltage trauma, marked by greater burn extent, predominantly vertical electrical flow due to contact with overhead lines, and significantly higher surgical complexity—including increased rates of fasciotomies and amputations. Despite comparable mortality, the clinical burden for train-surfing victims is substantially higher, reflected in longer ICU stays and more operations per patient. These findings underscore the urgent need for targeted prevention strategies addressing youth engagement in train surfing. Public health campaigns, railway infrastructure modifications (e.g., deterrent systems or physical barriers), and early educational interventions could play a critical role in reducing these preventable injuries. Furthermore, trauma centers should be prepared for the specific reconstructive and critical care demands posed by this high-risk group, emphasizing the importance of specialized multidisciplinary management protocols.

Background: High-voltage electrical injuries (HVEIs) represent a complex and life-threatening entity, frequently involving multi-organ damage. While traditionally linked to occupational hazards, train surfing—riding on moving trains—and train climbing—scaling stationary carriages—have emerged as increasingly common causes among adolescents. Popularized via social media, these behaviors expose individuals to the invisible danger of electric arcs from 15,000-volt railway lines, often resulting in extensive burns, cardiac complications, and severe trauma. This study presents a 30-year retrospective analysis comparing cardiac biomarkers and clinical outcomes in train-surfing injuries versus work-related HVEIs. Methods: All patients with confirmed high-voltage injury (≥1000 volts) admitted to a Level 1 burn center between 1994 and 2024 were retrospectively analyzed. Exclusion criteria comprised low-voltage trauma, suicide, incomplete records, and external treatment. Clinical and laboratory parameters—including total body surface area (TBSA), Abbreviated Burn Severity Index (ABSI), electrocardiogram (ECG) findings, intensive care unit (ICU) and hospital stay, mortality, and cardiac biomarkers (creatine kinase [CK], CK-MB, lactate dehydrogenase [LDH], aspartate transaminase [AST], troponin, and myoglobin)—were compared between the two cohorts. Results: Of 81 patients, 24 sustained train-surfing injuries and 57 were injured in occupational settings. Train surfers were significantly younger (mean 16.7 vs. 35.2 years, p = 0.008), presented with greater TBSA (49.9% vs. 17.9%, p = 0.008), higher ABSI scores (7.3 vs. 5.1, p = 0.008), longer ICU stays (53 vs. 17 days, p = 0.008), and higher mortality (20.8% vs. 3.5%). ECG abnormalities were observed in 51% of all cases, without significant group differences. However, all cardiac biomarkers were significantly elevated in train-surfing injuries at both 72 h and 10 days post-injury (p < 0.05), suggesting more pronounced cardiac and muscular damage. Conclusions: Train-surfing-related high-voltage injuries are associated with markedly more severe systemic and cardiac complications than occupational HVEIs. The significant biomarker elevation and critical care demands highlight the urgent need for targeted prevention, public awareness, and early cardiac monitoring in this high-risk adolescent population.

Background: Deep sternal wound infections (DSWIs) remain a serious complication after median sternotomy, often requiring complex wound management strategies. While modern approaches include vacuum-assisted closure (VAC) and plating techniques, the pedicled pectoralis major muscle flap (PMF) continues to play a pivotal role in surgical reconstruction, especially in cases with sternal destruction or osteomyelitis. Methods: In this retrospective single-centre analysis, 166 patients with DSWI following cardiac surgery were reviewed. Clinical data, comorbidities, laboratory parameters, and surgical management were evaluated. Logistic regression was performed to assess predictors for reinfection and need for reoperation. Results: Initial wound revision was most frequently performed using sternal rewiring (60.2%), followed by reconstruction with a pectoralis major flap (33.7%). Despite initial surgical treatment, 27.1% of patients developed post-revision wound healing disturbances, and 24.1% ultimately required a second surgical intervention. Among second-time procedures, VAC therapy (32.5%) and PMF reconstruction (20.0%) were the most common approaches. Reinfection was significantly associated with higher preoperative EuroSCOREs (p = 0.044), while initial rewiring carried a higher risk of treatment failure compared to the pectoralis major flap (p = 0.0024). Conclusions: In the setting of sternal destruction or osteomyelitis, the pectoralis major muscle flap remains a fast, effective, and robust solution. Despite its long-standing use, it continues to offer excellent vascularized coverage and infection control in complex DSWI cases.
