Summary
Electrical injuries treated at a Canadian burn unit resulted in significant limb loss and morbidity, particularly in the upper extremities. Despite reconstructive microsurgery, persistent sensory deficits limit functional recovery and reemployment options for patients.
Area of Science:
- Trauma Surgery
- Burn Care
- Microsurgery
Background:
- The University of Alberta Hospital's Firefighters' Burn Treatment Unit has treated 1399 thermal injury inpatients over a decade.
- Electrical injuries constituted 5.3% of admissions (74 patients), predominantly affecting males (95.9%).
Observation:
- Electrical injuries, though smaller in Total Body Surface Area (% TBSA) and associated with shorter hospital stays and lower in-hospital mortality compared to other thermal injuries, led to significant morbidity.
- Work-related activities accounted for 74.3% of electrical injuries.
- 19 amputations were performed, with 12 in the upper extremity, often requiring reconstructive microsurgery.
Findings:
- Patients with electrical injuries, especially in the upper extremity, experienced delayed limb loss and substantial persistent sensory impairment post-reconstruction.
- Microsurgical reconstruction provided acceptable wound coverage but often resulted in poor sensory recovery, impacting functional outcomes and reemployment.
- The study highlights delayed tissue loss as a significant factor in morbidity following electrical injuries.
Implications:
- Further research into the cellular biology of delayed tissue loss after electrical injury is crucial.
- Understanding these mechanisms could reduce amputation rates and improve functional outcomes for burn patients.
- Targeted interventions are needed to mitigate long-term morbidity and enhance reemployment prospects for individuals with severe electrical burns.
